What are Flying Wyverns?

Flying Wyverns (Japanese 飛竜種) are large, bipedal monsters that have two wings. These Wyverns are known as "True Wyverns". However, there are some Wyverns that are quadrupedal, operating their wingarms as forearms instead like Tigrex and Nargacuga. Some are flightless despite their classification as Flying Wyverns, like the Akantor and Ukanlos. These wyverns show their Wyvern ancestry by the small forewings on their two front limbs. Flying Wyverns make up a large majority of the monsters in the Monster Hunter franchise.

To attack enemies and prey, he will usually strike quickly from the sky like a hawk and sink his claws into their body, poisoning them. If that fails, he will use his powerful fireballs.
  • He is able to produce his powerful fiery breath by multiple organs, flame sacs. While spitting fireballs, he actually burns his own throat while doing so but, its throat is specialized to recover from the fire very quickly and some Rathalos have found other ways to use their fire like with powerful bites combined with the flames.
  • The Rathalos's eyesight is very good, rivaling some birds of prey.
  • Rathalos is one of the most common Flying Wyverns in the MH World. Part of the reason is that Rathalos will fly to far away areas during the breeding season in order to find a mate.

  • A few of them might have been mistaken for Silver Rathalos in the past.
  • Zerureusu only appears on the Tower when light shows up in the area. This has been happening since ancient times.
    • Most of this suggest to migrational behavior during certain times to some fans.

Espinas

  • Espinas is a Flying Wyvern mainly found living in the Great Forest.
  • In the Great Forest, it is known to the locals as the Lord of the Great Forest. The reason for this is because, in ancient times, Espinas reigned over the Great Forest, though it was only a Flying Wyvern. In those ancient times, Espinas fought and defeated an Elder Dragon that was trying to control of its home. This makes Espinas one of the few monsters equal to an Elder Dragon.
  • Espinas get the title, Thorn Wyvern, due to the many thorns found throughout their body.
  • Espinas are known to feed on slow-moving Herbivores, such as Mosswine and Aptonoth, and Neopterons.
  • Espinas are known to lay perfectly still while sleeping due to this being their hunting style. While sleeping, the green color gives it good camouflage in its environment, making it just mimic the background though not perfectly. If prey is close enough, they may or may not strike it. Compared to other Flying Wyvern species, the hunting style of Espinas isn't at all very aggressive.
  • Usually if attacked to a point where it wakes up, Espinas won't bother to attack the threat. The reason why is because of the thorny body. The thorns act as both a weapon and as an armor for Espinas, meaning Espinas have very good protection from attacks. These thorns also contain poison that is found throughout the Espinas' whole body. They use this to their advantage and usually wait for the threat to give up. Espinas will occasionally swing their tail, flap their wings, and bite at enemies to make them give up quicker.
  • If greatly damaged while the threat is attacking or if the threat truly is a danger, Espinas will become aggressive as a last resort. Blood veins will be seen on its body, making its armor softer but also allowing it to move faster. By making its armor softer, it makes so the armor doesn't inhibit its movements.
  • Espinas are able to breath poisonous fireballs at their enemies. These fireballs not only burn prey but, also poisons them. These poisons not only slowly kill prey but also can even paralysis prey. Even if a creature survives a blast from the fireball, the poisons will eventually spread throughout the body.
  • On an Espinas's scales are the scars of all its battles. The scales are far beyond any normal Flying Wyvern's scales.
  • The hardness of its shell is abnormal, it isn't easy to damage this shell without Espinas being angry.
  • The thorns are very tough and sharp. These thorns ooze poison when Espinas is angered. The miasma, from the thorns, is enough to stop someone from touching the thorns.
  • Its tail is tough to cut off! Even when cut off, the tail still oozes with poison.
  • A gem produced inside the Espinas is red, angry like Espinas.
  • HC Espinas are older Espinas with more defensive styles.

Zenith Espinas

  • Unlike other Espinas individuals, its horn and poison have heavily developed in nature over some years.
    • Noticeably, a thorn plant is also growing on this Zenith Espinas.
  • By heavily developing its horn more than other Espinas, Zenith Espinas is able to fight better in melee situations.
  • Unlike other Espinas individuals, it has a more deadly poison that kills prey at a quicker rate. This is due to Zenith Espinas having multiple venom glands that combine different types of poison together.
    • The poison of Zenith Espinas actually glows a vivid purple, as if it was a beautiful flower that won't harm anyone.
    • Normal antidotes can't even cure this poison.

  • Even if the spines of Zenith Espinas are gently touched, it'll still cut and fill the victim with glowing poison.
  • Zenith Espinas's shell combines strength and beauty. Strangely, it seems no poison is on it.
  • Zenith Espinas has Lethal Poison Sacs that accumulate various poisons. No studies have been done on these special sacs due to the poison produced by them being too lethal.
  • Occasionally, a Zenith Espinas will produce a large red gem in its body. This gem is identical to the monster's rage.
  • The bone marrow of Zenith Espinas circulates and releases poison throughout its body.
  • The poisonous tail of Zenith Espinas has very few poisons in it, meaning people can handle it with relative ease.
  • Zenith Espinas's needle wingtalons are scarlet in color. Due to poison flowing in these wing claws, most people hesitate to touch them.
  • Its heavy wings have a splendid appearance. When the Zenith Espinas is threatened, veins will be seen on the wings.
  • The venom gland of Zenith Espinas is the organ that produces the poison. Interestingly, when carved off, the organ will stop producing poison.
  • The horn and spines of Zenith Espinas are all connected to one of many of its poison sacs.
  • The extreme horn of Zenith Espinas has changed due to an unknown mutation. Thousands of venom glands connect to this singular horn and a large narrow cavity can be seen inside the horn. This how its poison has changed.

  • Meraginasu is completely blind. In order to see with it uses its powerful well-developed hearing to find prey. It will constantly listen to find prey while roaming around. When it identifies possible prey, it will turn to try to face it, gold markings will glow on its body, and it will relentlessly attack threats until their dead or can't hear them anymore.
    • Sonic Bombs don't affect it because they have a different sound frequency that doesn't bother Meraginasu.
  • Its roar can crack the ground around it easily.
  • The Darkness Element is Ice + Dragon and is used by Meraginasu. It uses this element for its shocking mind-blowing speed and to produce some of its attacks such as its roar, breath, and tornado.

  • Special crystals found inside Meraginasu might actually be the source of the Darkness Element in Meraginasu. These crystals completely engulf light and are apart of some of its organs.

Seregios

  • The Guild has known about Seregios's existence for a long time and according to them, Seregios doesn't live in the Old Desert/Dunes or any of the other environments they've been seen in. They come from a different land and in a sense can be considered an invasive species from a different land, much like Baruragaru.
    • It doesn't seem like the Seregios live in Deserts rather rocky, mountainous environments.
  • The Guild did let hunters hunt Seregios but they were very limited due to how rare these monsters were until they recently became a problem in the Old World. As of now most didn't even know about this monster, including many hunters.

On impact, these scales can leave complicated gouges in prey along with rocks. The wounds these scales leave behind are very painful and the pain from that injury can stay with prey for a long time.
  • The reason why the Seregios have recently appeared in so many areas is because of the Apex Seregios that kicked them out of their land. The Apex Seregios had been infected by the virus but was able to overcome it and became much dangerous from it. It had now used this new found strength to eliminate rivals of its own species more easily.
  • Its horn is described to be a very thick, sturdy blade.

  • When it does its electrical field, it uses its tail as support but as they get more experienced with their electrical powers, they will climb less and use their tail less often, unless they need it for stronger electrical attacks. These Khezu are the HC Khezu.
  • Khezu mostly prefer eating live prey. When they smell prey around, they will move quietly on ceilings or walls in order to ambush their prey. When its close to its prey, it will extend its neck out, grab it, and then swallow it whole.
  • Its neck is flexible from its skin.
  • Their salvia is acidic in nature but not as strong as a Deviljho's salvia, which melts through armor.
  • Despite being blind and using smell, they seem to have another way to see prey because, in experiments done by the Guild, the Khezu would actually smell the corpse of a Kelbi or larger herbivores and avoid it but would eat any small animal that was alive with them. It is believed that they may also use their electricity to sense heat in a way but, there are other different theories behind this.
  • Khezu breeds by paralyzing prey, usually a medium-sized creature like a Popo, laying the eggs on the still alive victim, and leaving them to hatch on their first meal. When the whelps reach a certain size, they'll move to tight places like crevices, or even the shed skin of a Kushala Daora, and wait for another potential victim to latch onto.
    • Occasionally, hunters are attacked by them while mining.
  • Interestingly, Khezu Whelps are a delicacy but adult Khezu aren't a delicacy.
  • When hunting wasn't truly common in the world, Khezu was only considered a myth. The only thing known about it in those old times was its strange appearance.
  • Its "tail" isn't exactly a tail, it is actually a mouth... It seems while the Khezu was a whelp, that "tail" was actually the mouth it used to feed on the blood of prey. As it continued growing, its real mouth further developed, allowing it to feed the way it does eventually.
    • This likely also applies to Gigginox.
    • Some grown teeth can be seen inside the "tail".
  • The reason Khezu has so much fat inside its body to protect itself from its own shocks. If it didn't have this fat, it would kill itself with its own shock.
  • Pale Extract is used for many different medicines.
  • When Khezu dies, Thunderbugs will actually feed on its electrical sac.
  • Some Khezu have been found to have hair on their belly.

Zenith Khezu

  • Zenith Khezu is a powerful Khezu individual that has heavily developed its head. It has heavily developed this part in order to capture prey more efficiently.
  • Zenith Khezu's skin is plump yet weird. Words can't describe how this skin feels like, though one touch and the handler doesn't want to let go of the material.
  • Its albino blood flows throughout its body. This blood is blue in color with a decent smell.
  • The insulting film of Zenith Khezu is under its skin. This material seems perfect for handling different types of electricity.
  • Zenith Khezu has tiny hairs growing all over its body. These hairs allow it to sense the vibrations of prey throughout its entire body.
  • Its Zenith Hide sparkles like a bright jewel. This hide has changed due to a stronger discharge, compared to a normal Khezu's hide.
  • Zenith Khezu rarely produces fluid in its body, which resembles a pearl. This fluid is a little thin.
  • This Khezu's stomach has never been looked at by researchers due to it being disgusting! Even for a normal stomach, Zenith Khezu's stomach is pretty big and full.
  • Zenith Khezu's wings are wonderfully soft yet fully-formed. Scars from previous fights can be seen on these wings, showing this Flying Wyvern's true strength.
  • The "sucker" is the name of a Khezu's tail. Though surprisingly soft and pleasant, the sucker allows Zenith Khezu to cling to ceilings with ease.
    • Some suckers have enhanced adsorption.
  • Zenith Khezu's head is an important piece needed for further research. Due to an increase in electrical power, this Khezu's head has changed greatly through mutation. The amount of electricity that Zenith Khezu can produce is beyond any normal Khezu.

Red Khezu

  • Red Khezu is normal while Khezu is a genetic defect.
  • Its neck can stretch much farther than the normal one and it has a lot more muscle in its body.
  • Red Khezu can be found living in the same areas as Khezu but, they are better adapted for colder environments, unlike Khezu.
  • Red Khezu skin is also soft but, is better known for the many colors in its wings.

Giggi and Gigginox

  • Gigginox evolved from the same ancestor as Khezu.
  • During the day, they sleep much longer than most other monsters in the area but, at night they become truly active. They will spend some time awake during the day but, if they instantly sense potential prey in the area, they will actively stalk it in the caves.
  • Despite their looks, they are quite intelligent compared to some other Flying Wyverns.
  • Their red underside has many hairs on them sort of like some geckos with their toes.
  • Just like Khezu, it produces a similar mucus-like substance on its body, though this substance isn't really produced while its calm, making it look dry. Its mainly produced when enraged.
  • If hunters are carrying a torch, the chances of a Gigginox attacking them increases.
  • Gigginox spits the globs of poison on the ground because if its able to get something to inhale enough of the poisonous gas, it will have a chance to kill it.
  • When enraged, it combines the toxins with the mucus, giving it a darker appearance.
  • Gigginox saves food in the caves. Gigginox may also leave behind corpses in caves to make it easier to catch prey.
  • The occasional outbreak of Gigginox is sometimes caused by one laying egg sacs like crazy or just by multiple Gigginox.
  • The moment the Giggi are born, they are on their own. Despite hundreds of them being born by one Gigginox only a handful of them will survive. While small, Giggis can produce their own poison but not as effectively as Gigginox. From this, they need to feed on the blood of other monsters not just to feed themselves but to also make their own poison. When they make it to a certain size, they will cocoon themselves by using a thread from their mouth to make a cocoon. These cocoons can often be seen in the caves of the Tundra.
  • The claws or talons of a Gigginox are used for magical properties.
  • Gigginox has short teeth and fangs much like Khezu, which are used to eat the frozen corpses.
  • Their poison sac is said to glow with a creepy eerie glow.

Baleful Gigginox

  • The Baleful Gigginox is a genetic mutation of Gigginox. It gets its electrical abilities from its and Khezu's ancestor.
  • Where their poison organ is supposed to be is now where their electrical organ is at.
  • Baleful Gigginox cannot reproduce or lay egg sacs full of Giggi from its genetic defect.
  • Unlike Gigginox, who saves prey, Baleful Gigginox actually actively hunt for prey, even outside caves.

Monoblos

  • Sightings of them are rare and their population is smaller than most other wyvern species, despite them being found in a lot of deserts.
    • The reason why Monoblos is solo only is because of their small numbers and to prevent hunters from overhunting them.
  • Monoblos are confirmed to be Herbivores like Diablos.
  • They are less aggressive than Diablos and even seem to be shy.
  • Their legs are very powerful and their speed is extremely fast. Also, while charging their horns are strong enough to pierce through rock.
  • While underground, they depend on hearing.
  • During breeding season, males flash their red colorful frills to both attract mates and to scare off rivals. Monoblos in-general uses the frill to scare off threats but if that doesn't work then they'll attack threats dead on.
  • From not having any breath based attacks they have better larger well-developed lungs, which help them to inhale deeper and produce their famous ear-splitting roars.

From sand covering Monoblos it doesn't show its true color, which is supposed to be red on some parts including its horn.

    • The HC Monoblos shows a Monoblos's true colors.
  • Monoblos like some animals may have multiple hearts. This is theorized by the Guild.
  • The sand makes its shell harder.

Shattered Monoblos

  • Shattered Monoblos is a special individual.
  • It is considered to be about as active as a normal Monoblos.

White Monoblos

  • The White Monoblos is a subspecies of Monoblos.
  • The White Monoblos population is a lot lower than the normal Monoblos species.
  • They are a lot more aggressive than a normal Monoblos.
  • White Monoblos kill a few hunters every year though the reason why is because of its armor. Its armor is praised by hunters everywhere since hunters can truly be called a hero from hunting it.

Diablos

  • Diablos numbers are much higher than Monoblos numbers. It's even comparable to most other Flying Wyvern species.
  • Female Diablos grow larger than male Diablos.
  • Diablos are extremely territorial and can cause a lot damage. They have even been reported to attack whole groups of hunters and destroy barriers that were made. This aggression can even go to their own species, including with their own mate or young but this is most commonly seen by males protecting their turf.
  • One swipe of their tail is much stronger than a Steel Hammer.
  • Diablos have better-adapted hearing but their vision is poor.
  • The black smoke that comes out of their mouth seems to be a gas from one of their organs.
  • Diablos Hearts are in high demand like Monoblos Hearts for food.

Crimson Diablos

  • In a particular small region, it is said that a strange mutation of Diablos was born. This particular Diablos had a crimson-colored shell, was larger, and was far more aggressive than any normal individual.
  • This Diablos was originally only a rumor at the time but, later other regions actually reported Diablos similar to this. These other Diablos looked the same as a normal individual, however, they had one horn and were known to be quite berserk in nature. Due to this berserk nature, these individuals would violently fight threats or rivals until stained with the blood of foes, turning them crimson in color.
    • There were also sightings of one these Crimson Diablos in different regions of the Desert, though this one was said to be bulkier and still roams the endless sands to this day.
  • These Diablos can be best said to be rogue.

Massacre Demon Diablos

  • Massacre Demon Diablos is a special individual of Diablos.
  • Unlike normal Diablos, Massacre Demon Diablos's body is covered in bluish blood and one of its horns have developed strangely due to certain factors.
    • When enraged, the red veins will appear on its body.
  • Like Diablos, this Deviant is highly aggressive. However, a Massacre Demon Diablos is described to be quite rogue or brutal when it encounters a threat, especially if it is a hunter. When it sees a hunter, Massacre Demon Diablos instinctively sees them as a threat and attacks in an instant. This individual will go out of its ways to make sure that threat doesn't return alive.
    • Massacre Demon Diablos horn was cut off by a hunter while it was still young. This is the reason why it hates hunters and sees them as a threat instinctively.
    • This is the reason why the Wycademy gave it the additional name, Massacre Demon.
  • When greatly enraged, Massacre Demon Diablos's secreted body fluids will begin to evaporate due to its intense body temperature, causing a sort of steam to spread off its body.
    • This state is called its Massacre Charging State.
  • The evaporation of the body fluids causes a steam explosion, which can easily push off hunters that are near it or dare to attack it.
  • Once in this mode, Massacre Demon Diablos will only want to attack one particular hunter, while it ignores the others on the team.
  • It becomes weaker to attacks in its second Rage Mode.
  • A Diablos can regrow its horns. Though it can regrow its horns, the shape they will take is random and usually won't be the same shape as they were before.
  • According to an interview, Massacre Demon Diablos is supposed to be the leader of the Deviants and strongest one in the game.

Black Diablos

  • The Black Diablos's color is a warning color to other species yet a signal to male Diablos.
  • They aren't very caring like Nono Orugaron and the Rathian towards their mates.
  • They stick to territory more often than usual as they wait for the males to come looking for them.

Varusaburosu

  • In ancient times, a huge long drought struck the desert, causing many oases in the desert to dry up completely. Due to this long drought, Varusaburosu's ancestor moved to harsher volcanic regions and evolved to fit with this harsh environment. The reason why Varusaburosu's species stayed in the Volcano is because of a particular cactus found only in the Volcano.
  • Varusaburosu gets the title, Flame Horn Wyvern, due to fire coming from its horns.
    • Fire comes from its tail and horns due to a flammable gas that it produces inside its body, which ignites when exposed to air.
  • Varusaburosu have an obsession over the cactus. This obsession makes Varusaburosu super aggressive causing it to relentlessly attack foes that are holding the cactus. The reason for this obsession is because the cactus will dramatically increase the physical strength of Varusaburosu and without the cactus being eaten its very own flames will slowly disappear, making it a lot weaker.
    • When eaten, Varusaburosu’s fire will turn purple. This shows the cactus has increased its strength.
  • The cactus is covered in many thorns. These thorns don’t bother Varusaburosu but the thorns can cut into other creatures quite easily.
  • Varusaburosu's carapace has high heat and is said to be deformed along with blackened by the heat.
  • The shell of this Varusaburosu is hotter, better quality, and harder. The chance of this shell going bad is pretty much impossible.
  • Varusaburosu's tusk is sharp and has some weight to it.
    • Some tusks are thicker and sharper. These can't be processed until cooled, do to the tusk being hot to the touch with your bare hands.
  • Just by drooling blood on the ground, it will leave behind smoke on the ground.
  • Some of the finest blood from a Varusaburosu, it will ignite the moment it comes in contact with hot air
  • The rare gem produced inside Varusaburosu's body has a chance of exploding, leaving behind quite a shock.
  • Their tail has a very distinctive appearance. From the tail of Varusaburosu, a flammable gas is produced inside the tail.
  • Varusaburosu's horns are said to have gotten harder from its constant digging through the hard earth.
    • The harder horns are used for decorations.

Basarios

  • Basarios is the juvenile form of Gravios.
  • It gets its title, Rock Wyvern, do to it being as stiff as a rock.
  • Basarios hides underground for camouflage. Hiding helps it hide from predators and allows it to ambush prey. Basarios are known to feed on Nepteron and other small prey.
  • Their shell is inferior to a Gravios’ shell due to their shell still being underdeveloped. Despite this, their shell is still very powerful.
  • Inside a Basarios’ stomach is a special bacteria that processes ore in the stomach, allowing Basarios to get nutrients from the ore. This bacteria also helps develop more powerful armor for the growing Basarios.
    • Sometimes eating ore just doesn’t give them the nutrients they need so they feed on live prey for proper nutrition occasionally.
  • Basarios are mostly found living in volcanic regions though can also be found living in swamps and forest areas.
    • Commonly, Basarios are found to have some volcanic properties on their shell.
    • Occasionally, some Basarios are burnt badly by lava causing them to be charred black in color. This color is known to follow them for their whole life.
  • To kill prey and protect themselves, Basarios will use a powerful toxin released as a gas onto the ground.
  • Basarios usually can’t breathe beams of fire so instead just expel fire or spit hot flames. Some more powerful Basarios are able to breath beams more often than others, suggesting that they are older.
  • Often ore can be found on a Basarios’ head and tail.
  • If their shell is destroyed, hunters may be able to find ore hidden under the rocky shell.
  • Basarios Tears are faintly pink gems found near the tear ducts of a Basarios.
  • Basarios are targeted by many poachers.
  • HC Basarios are said to be special individuals.
    • Rarer individuals even are able to send rocks filled with poison gas around them as a trap against threats.

Crystal Basarios

  • Crystal Basarios is a special individual that has been sighted in the Dark Veil Forest.

Ruby Basarios

  • Ruby Basarios are a subspecies of Basarios for right now.
    • From Ruby Basarios being recently discovered, the Guild doesn't know much about them.
  • Their title, Peach Rock Wyvern, comes from their appearance.
  • Due to the crystals on Ruby Basarios’ back, it has better camouflage than Basarios and an extra weapon. It will shake the crystals off its body to deal damage to any nearby threats for defense.
  • Ruby Basarios are rare to find so the Guild is always looking for new specimens and reports on them.
  • Ruby Basarios’ ecology is pretty much the same as Basarios’s, however, the Guild’s main question is if it keeps the crystals as it gets older or loses them.

Sandstone Basarios

  • Recently, the Hunter's Guild has received reports of Basarios in the Thunderous Sands. After much investigating, Sandstone Basarios was discovered by them as a Lone Species.
  • Its appearance has changed due to it feeding on sandstone, giving it the title Sand Rock Wyvern.
  • Sandstone Basarios is indeed the same species as Basarios, it just moved to the Thunderous Sands for unknown reasons. Though it is the same species as Basarios, some scholars still believe it is another species.
  • From its change in climate, the bacteria it once produced is gone for the most part. It now can't produce any fire-based attacks, however, this has been replaced with it producing and breathing sand at foes. It can even still produce poisonous and coma-inducing gases.

Gravios

  • Gravios is the adult form of Basarios.
  • Gravios gets the title, Armor Wyvern, from its stone-like shell that sometimes contains ore.
    • They are also sometimes called Armored Champions and Stalwarts of the Volcano.
  • Gravios is the largest and heaviest Flying Wyvern.
  • The Gravios’ shell has become harder due to its growth. This new shell also allows them more mobility, unlike Basarios.
  • Despite the harder shell of Gravios, its shell can be destroyed.
  • Gravios are known for being highly territorial. They will do all they can to eliminate a threat, no matter how powerful it is.
  • The wings of Gravios have started to degenerate though they are still able to fly for short burst.
  • Inside a Gravios’s stomach is a special bacteria that processes ore in the stomach, allowing Gravios to get nutrients from the ore. Gravios have a strong taste for explosive ores. These explosive ores help allow it to breathe beams.
    • Despite being fully grown, Gravios sometimes can’t get all their nutrition from the ores alone so occasionally they must hunt.
  • From its giant size and armor, Gravios are able to resist the intense heat from the lava. Its body can even contain lava for short periods without the armor covering its body. This allows Gravios to swim in lava to travel far distances.
  • Gravios’s major organs are in the center of its body so it can’t take up to much heat.
  • It has a high thermal energy in its body from feeding on explosive ore. They hold large amounts of this energy in order to save it whenever they decide to leave to other areas so Gravios can defend themselves.
  • Periodically, Gravios release hot gas from their body in order to cool down.
  • When feeding Gravios are known to unleash a white gas that puts potential predators to sleep.
  • The beams of Gravios can easily go through even the toughest of rocks.
    • Its suggested that Gravios may use it as a tool in some way as well.
  • Gravios can vary on how they use their beams but most commonly a Gravios uses it as a weapon.
  • Despite their huge size, Gravios have one major predator. This predator is the rare Akantor.
  • The wings and meat of Gravios is food to many different regions.
  • Gravios and Diablos share the same ancestor.
    • The direct ancestor to Gravios is Gureadomosu.
  • The cortex of a Gravios is also known as Mediastinum.
  • The robust crown of some Gravios are already weapon-worthy.

Black Gravios

  • Black Gravios isn’t a Subspecies of Gravios. Black Gravios are black in color due to them being burnt up by lava while they were still Basarios combined with large amounts of heat.
  • From being black in color, they absorb more heat and hold large amounts of heat inside their body, which is why they breathe their beams and release gas more often.
  • From the more heat a Black Gravios has absorbed, its shell is much stronger and sturdier than a basic Gravios shell.
    • This shell can even resist some ice element and dragon element attacks.
  • The HC Gravios and HC Black Gravios seem to be older individuals that have farther changed.
  • Even red-hot magma can’t damage this stout shell of some Black Gravios.
  • Scalp of the Black Gravios looks like a terrifying black mask.
  • Black Gravios crown is cranial plating capable of withstanding powerful blasts of breath.
  • Some marrow from Black Gravios ignites instantly upon air contact and requires extremely fast processing technology. The blood in the marrow can even melt rocks.

Gureadomosu

  • In ancient times, Gureadomosu lived in the many oases in the desert for water due to their semiaquatic behavior. Though in those times a huge long drought struck the desert, causing many oases in the desert to dry up completely. Due to this long drought, most Gureadomosu left the desert and moved to new lands in search for a water source. Some Gureadomosu, however, moved to the underground lakes in the desert and began almost exclusively living in them. However, recently water has begun to decrease in these underground lakes, causing some Gureadomosu to move to the surface in search of a new water source. Nobody knew about their existence until recently.
    • The Gureadomosu that went to new lands eventually became the Armored Wyvern', Gravios.
  • Due to Gureadomosu being a very ancient species, the Guild wanted hunters to capture specimens so they could study them. However, traps were found to not work on them. Despite this Gureadomosu are allowed to be hunted due to them affecting the desert’s ecosystem in a very major way.
  • Moss has been found to be growing on their shell plus their shells look brittle from the conditions they live in. The moss gives Gureadomosu better camouflage, helping it mimic the rocks in the caves.
  • The tubes found throughout parts of their body are used for capturing and sucking up large amounts of water inside their body. Gureadomosu store vast amounts of water inside their body so they can survive in the hot desert during long droughts or when a water source they live in dries out. However, the tubes are also used to shoot out vast amounts of water when trying to protect themselves from threats. When angered, these wyverns will send water in all their tubes in preparation to fight off its predator. The force of the water can even injure monsters like Plesioth with ease.
  • Gureadomosu are said to use most of their water at close range to protect themselves, giving them the title, Water Fortress Wyvern.
  • The more water a Gureadomosu uses, the more powerful its attacks.
  • Gureadomosu are actually able to swim in water.
  • Gureadomosu make up for their huge bulk by using their tail to shoot water out like a jet to move.
  • A Gureadomosu’s shell is covered with moss and has tubes that send water throughout its body. Some shells are finely grown or developed.
  • Its skin has good water retention and strength. In some cases, the skin is leather-like and with a single squeeze water comes out!
  • Moss found on Gureadomosu only gathers and grows in clean water. This moss is known to only grow on Gureadomosu.
    • Its suggested that this moss and Gureadomosu have a symbiotic relationship.
  • A special gem formed inside Gureadomosu only comes from monsters that have lived in ancient times. It is enough to feel the very beginnings of life.
  • The tubes are flexible. By stretching the tubes it aids in discharging water plus adjusting the very water pressure.
  • The tail has a very specific shape. It allows it to propel itself like a jet. From moss covering the tail, it is needed to process and carefully removed.
  • Their water sac is water that is ready to drink! The water has somehow been purified inside Gureadomosu’s body but how is a mystery.
  • The surface of the wings is cool. The wings have weight to them do to due to all the moisture inside the wings.

Gurenzeburu

  • Gurenzeburu has adapted to living in the high stormy mountains of the Highland.
  • They get the title, Barbarian Wyvern, from how aggressive they are though they aren't as aggressive as people think. Gurenzeburu usually doesn't try to hunt the herbivores but instead coexist with them and even have a relationship with them. Gurenzeburu prefer to feed on plants, certain ores, and insects in the Highland. These herbivores even actually depend on Gurenzeburu for protection. Gurenzeburu rarely try to pounce and kill herbivores such as Erupe and Burukku but will pounce forward at any threats to try to intimidate them. They also do it because its a habit of theirs.
  • Gurenzeburu are quite calm while in their territory, undisturbed, but can turn quite aggressive the instant they spot a threat or rival in their territory.
  • From eating special ores, it gains a cover of quartz-like mineral which reinforces its shell, horn, the tip of its wings, and grows multiple thorns on its tail tip. This basically makes it a living weapon as all of these parts are used in battle and it can even be said that it uses its whole body to fight. Combined with their strength, they can easily knock down stone pillars with their horn, their wings can stir up winds, and even can be used for powerful body slams. From this, it is recommended not to use Pitfall Traps against them from them being able to still attack, even while in the trap. At long distances, Gurenzeburu will breathe water in a few different forms at foes.
  • From these ores being on its body, those parts actually are like Lightning Rods though Gurenzeburus aren't really damaged by lightning strikes. Smarter, stronger Gurenzeburu can use this to their advantage and toss them around the area making traps for threats, using the thorns both defensively and offensively.
  • During storms, Gurenzeburu becomes a lot more aggressive than usual and they can also tell how violent a storm is just by looking up at it. Some seemingly older Gurenzeburu have actually learnt how to use water in more unique ways, even somehow using water in their physical attacks during heavy storms.
  • Lusters can be found on the scale of Gurenzeburu and you get water from them.
  • Its claws are very dense, making them much heavier than they look.
  • Its wings can cut up threats with ease.
  • The tail of a Gurenzeburu is very tough to cut off due to many muscle fibers in the tail.

Berukyurosu

  • Its title, Dancing Thunder Wyvern, is from how it moves in the sky as if it was dancing with grace.
  • Berukyurosu is one of the most feared monsters in the Gorge, powerful enough to be compared to some Elder Dragons.
  • There is corrosive fluids that travel through their whole body. These fluids contain ore and minerals in them and this is how Berukyurosu is able to produce high amounts of electricity through its whole body. Even small amounts of dust in the air around can conduct larger amounts of electricity around it for certain attacks like its Rage Mode Pound.
  • Berukyurosu hunt down their prey by discharging electricity.
  • Berukyurosu can actually burn themselves with their discharges but their parts have adapted to withstand this. Their bone marrow can withstand high amounts of electricity and it produces more blood than any other wyvern in them. Their fat helps them protect their vital organs from shocks. The scales and mane are able to withstand being burnt by the pluses of electricity and good at charging electricity. Despite this their internal organs are quite fragile.
    • Once one these organs are unable to produce lightning anymore, they will cause Berukyurosu to lose control of that organ and cause that organ to burn Berukyurosu.
    • In some cases, Berykyurosu will actually kill itself to avoid being captured and from it losing control of its organs.
  • Despite being colorful, its colors are used for camouflage and to make it look like some of the plants in the Gorge.
  • Its unknown if the eyes are immune to the shocks are not but they aren't really affected by Flashbombs like other Flying Wyverns.
  • Their fingers are used like a whip and the claws on them are used to rip apart objects.
  • When their mane turns red, this indicates that larger amounts of electricity are flowing through their body at a more rapid and violent pace.
  • They are considered to be the most intelligent wyverns thus far from their many battle styles with certain hunters. Each one of them fights differently and older Berus have made up many new tricks.
    • It has even been rumored that there is still more about these wyverns we don't know.
  • Its tail acts like a rudder while flying.

Doragyurosu

  • For some unknown reason, some Berukyurosu actually learn how to use an element known as Dark Thunder. These Berukyurosu mutate and change into Doragyurosu.
  • They have many of the same elements as the normal ones but with a few minor differences like color, spending more time on land, and more. The main difference is the element it uses. Unlike normal Berukyurosu, it somehow found a way to control and manipulate the Dragon Element by changing from the Thunder Element. It's been suggested that the environment may have played a role in its mutation.
  • Despite spending more time on land, Doragyurosu actually is still a very good flyer and its wing are even believed to be stronger than Berukyurosu's, suggested from how they can pull rocks out of the ground.
  • Doragyurosu is said to have several different stages of power.
  • HC Doragyurosu have control of their organs in their body and choose which will be doing what.
  • Phantom Doragyurosu are so rare that they are considered to be just stories or ghosts. It's said to be the Red Rajangs equal and to be more powerful than a lot of Elder Dragons from its destructive power.
  • The strongest of them all, the Supremacy Dorsagyurosu, is the rarest of them all. It is said to be able to burn the Great Forest Peak to a crisp and to have many mysteries behind it.
  • Its scale hold in heat.
  • Crystals have been found inside Doragyurosu's body from the compressed energy.

Zenaserisu

  • Zenaserisu is the predator that has been preying on the defenseless creatures of the Painted Waterfall as of late.
  • Covering Zenaserisu's body, tentacles, and tail are these long Condensed Blades used for ripping the earth apart.
  • The Condensed Blades allow it to fire water at foes in all directions.
  • Its wing's tentacles can rip out giant boulders easily, along with pull in prey.
  • Its hunting ban has been lifted for G-rank.

Anorupatisu

  • Anorupatisu is a Flying Wyvern discovered in the Polar Sea.
  • It gets the title, Violent Saw Dragon, from its aggressive temper and its long saw-like horn.
  • In the Polar Sea, Anorupatisu is called the Emperor of the Polar Sea due to it being the top predator of the area. Able to hunt from land, air, and sea.
  • Anorupatisu needs to eat a large amount of prey in order to control its body temperature and survive the cold.
  • Anorupatisu recognizes any monster in the area as a potential meal, possibly even other Anorupatisu.
  • It is believed to be one of the fastest Flying Wyverns found so far and its flying rivals Berukyurosu and the Rathalos.
  • Anorupatisu are usually covered with scars of previous battles or hunts, showing they have an aggressive life.
  • The vapor known to come out of Anorupatisu is cooled by the cold air in the area. This vapor is used to produce icicles that will rain down with some of its attacks.
  • Recent studies show they may have special organs that produce the Dragon Element, that they use when they feel that their life is in danger and when they may die.
  • Anorupatisu are well known for attacking Pokaradon and occasionally Giaorugu.
  • An Anorupatisu's eye is a brilliant crimson, despite its name. Since it looks like a Sea Ruby in the Polar Sea, it is the Ruby of Ice and Snow.
  • The wing membrane is used as an abrasive and has a rasp surface.
  • The tail is also able to crack ice with a single swing.
  • An Anorupatisu's fang has the strength to chew through solid ice.
  • Its horn's shape is popular among hunters!
  • Anorupatisu's carapace is jagged in shape so it can cut through the ice easily.

Tigrex

  • A Tigrex's top speed is about 50km per hour or more.
  • Tigrex is most well-known for its roar, which isn't high pitched, but has a high volume that can destroy objects or dramatically push back objects. From this roar, it has been called the Roaring Wyvern.
  • Tigrex mainly live in the Deserts and Sandy Plains but have been seen in the Snowy Mountains, Tundra, and Frozen Seaway. They go to these areas to feed on the Popos, their favorite meal, from finding food in some of the areas they live in being difficult.
    • Tigrex could also be found living in some unusual areas.
  • They like areas with many different cliffs and height differences to attack prey.
  • Tigrex will relentlessly stalk their prey and will even track one particular target out of many others of the same species. They can sometimes be greedy and eat more than one prey item.
  • Tigrex like chasing down their prey before leaping on their prey and ripping it apart.
  • Tigrex don't have a territory and just wander from place to place while looking for prey. From this, the Guild keeps tabs on many Tigrex to see where their at and where they are possibly going. Sometimes the Tigrex might enter a monsters territory for both protection and food.
  • Most other Flying Wyverns fear Tigrex.
  • When enraged, its body becomes weaker to attacks and more bound to injuries.
  • The HC Tigrex is an old male Tigrex with some battle scars and larger horns to show his dominance.

Zenith Tigrex

  • After a long period of time, this Tigrex's claws have become more vicious.
  • Zenith Tigrex is an unrelenting force. Once it smells the blood of prey, it'll enter into a Feeding Frenzy and chase down that particular prey item only.
    • If a hunter has a Bleedblight, it'll enter Rage Mode and go crazy trying to pin down that hunter before feeding on them violently. Zenith Tigrex will only target hunters with the status effect.
  • This Tigrex's roar can actually destroy the ground under it, literally.
  • Its front limbs have vicious claws that have developed in savage fashion. It also has spiky protrusions all over its front limbs. Both these protrusions and claws can make a prey item bleed to death.
  • Zenith Tigrex has an attack similar to Akantor's Wind Tunnel, where it roars at foes in front of it and slowly turns as well.
  • Zenith Tigrex can send waves of the earth at foes with its front limb, along with a powerful gust of wind.
  • Much like Grimclaw Tigrex, Zenith Tigrex is known for slamming its claws into the ground, leaving behind mass destruction.

Grimclaw Tigrex

  • Grimclaw Tigrex is a Tigrex that claws and wings have developed more than usual.
  • The reason why its claws and wings are blue in color is because of blood vessels passing through its skin. This has helped its claws develop irregularly, severely changing them, making them harder and more savage.
    • These claws are known to soften when it is enraged.
    • Its tail and a part of its head are a blue color from this as well.
  • From it having these irregular claws, Grimclaw Tigrex is able to use its claws more often while attacking. This even allows it to destroy the ground in a destructive fashion or even throw massive snowballs.
  • Grimclaw Tigrex have been found to have roars that rival a Brute Tigrex's roar or even a Molten Tigrex's roar.
  • The scales of Grimclaw Tigrex have hardened greatly and are quite thick.
  • On the shell of Grimclaw Tigrex, blue blood vessels can still be seen pulsing like it wasn't dead.
  • The claws are full of bleeding from their harshness alone.

Brute Tigrex

  • The Brute Tigrex is a variant of Tigrex.
  • It is confirmed that this altered coloration is the result of extreme heat from volcanic ash and other such impurities that fuse with the Tigrex's shell. The presence of this ash seems to make its shell-less effective at insulating heat
  • They will attack the normal Tigrex with no warning.
  • This Tigrex burns energy faster than the normal species from its higher metabolism and it can't really tolerate the cold from this though it still seems to have some resistance against the cold of the desert at night.
  • Its roars are far stronger than the normal Tigrex's and even more destructive. Its roar can even kill prey at close range, not leaving a single mark on prey.
  • It is said to also have become darker from eating certain types of prey.
  • Its teeth, claws, wings, tail, head, and legs are stronger than Tigrex's.

Flame Tigrex

  • Originally scholars believed that Flame Tigrex was just a special Tigrex individual that used lava to armor its head and limbs, but this was proven false once they saw the charred remains of a hunter’s armor.
  • Though Flame Tigrex doesn’t have any fire sacs, it has a powerful ability known as Wyvern Breath. This attack allows Flame Tigrex to burn foes with a deadly roar that pushes volcanic ash at foes, as well as pushes them back with immense force.

Molten Tigrex

  • The Molten Tigrex is a subspecies of Tigrex.
  • It is said to have huge claws that far exceed the normal Tigrex species.
  • It was theorized to exist after the discovery of claw marks and prints far larger than those of an ordinary Tigrex. With no confirmed first-hand sightings, its existence remains a matter of debate among hunters.
  • Due to the Tower being surrounded by the Great Forest and due to the Great Forest having large amounts of oxygen, Molten Tigrex grew bigger than its relatives. It's said that Molten Tigrex has some type of gene mutation due to this environment.
  • In the Great Forest in ancient times, another primitive Tigrex Species, larger than even Molten Tigrex, lived there and it had a gene that allowed it to grow this big. This gene has evolved with Molten Tigrex. Now Molten Tigrex is the last trace of these behemoths.
  • The identity of the weird dust is stratum corneum, or in other words, dead skin due to its metabolism. Molten Tigrex's claws are metallic in nature and can ignite small bits of the scales with each footstep while charging.
  • From cracks in its shell and skin, hunters can see some of its muscles while in its 2nd Rage Mode.
  • The Molten Tigrex is larger than Tigrex and the Brute Tigrex but from its bulk, it isn't as fast or agile as the other two.
  • Only a hand-full of hunters are even allowed to hunt the Tigrex Rare Species and its numbers are small too.
  • They have red scales that explode when ignited.
  • Its roars are said to be stronger than the Brute Tigrex and even able to shake the ground.
  • Its secondary Rage Mode is known to the Guild as its Detonation State. This state is indicated by it having more blood vessels appearing on its body but on some unusual areas to ensure it can keep battling and fighting enraged beyond its normal limits. In this state, its explosive scales is released more frequently, its speed increases, and its strength increases. It also seemingly becomes smarter. The only two downsides to this state is that it can't stay in this state for long and it loses large amounts of energy in this making it weak to attacks and, extremely tired.
  • Its claws are used to ignite the explosive scales.

Diorekkusu

  • Diorekkusu is a Flying Wyvern Species that has evolved electrical abilities for both hunting and for protection.
  • It is a Tigrex Species but unlike other known Tigrex Species, its scales are extremely soft. It overall is a Tigrex through and through from its characteristics.
  • To protect its soft scales, it uses magnetism to make itself an armor out of ore. From high amounts of electricity coming from Diorekkusu's body, the ore armor will become blue in color. *The ore will fall off when impacted by attacks.
  • Diorekkusu also use magnetism to increase the power of attacks and to increase its speed with certain attacks. With older Diorekkusu, they will use it to change their environment for a short period of time and use it to their advantage to take down prey.
  • Its ecology is similar to Tigrex's though quite different.
  • Its roars are powerful but combined with electricity, they become twice as deadly.
  • Most electricity flows greatly through its head, legs, wings, and tail. When charging from any of these parts, its armor around that area becomes weaker to attack while charging up. Some of those parts will also change color when it uses charged attacks plus it's believed to have organs in those parts that help it produce lightning.
  • Diorekkusu is described to be as fast as lightning. Before running, it will pick up electricity in its legs in order to run fast.
  • Diorekkusu is considered to be one of the most dangerous Tigrex Species and Flying Wyvern Species around.
    • It is even said to have killed a few hunters.
  • Its bone marrow is charged with lightning and its tail charged as well, even after being cut off.
  • Its scales are always charged.
  • A Diorekkusu's shell can absorb large amounts of lightning.
  • Even with armor on its body, it doesn't lose its speed.
  • Diorekkusu is gray in color and is blue with its armor.

Pariapuria

  • Pariapuria are a Flying Wyvern with a primitive skeleton structure.
  • Despite its look Pariapuria is much heavier and slower than other Flying Wyverns. However, it takes advantage of its weight and uses it to perform strong attacks.
  • From its heavyweight Pariapuria prefer to stay on the ground rather than fly.
  • Strangely, Pariapuria's tail is similar to an ancient fish's tail and even has webbing between its feet.
  • Originally, there was a theory by the Guild that Pariapuria was still evolving to become a water monster that would eventually live completely in the water. This theory, however, has been debunked because Pariapuria rarely goes in the water though it still seems to go in the water to some extent.
  • All over Pariapuria's body is mucus. This mucus is slippery and repels adhesives.
    • From how slippery the mucus is Pariapuria can actually slip right out of Pitfall Traps easily.
    • This mucus can make crops grow endlessly.
  • Pariapuria are most well-known for their seemingly bottomless appetites. With a large number of sharp teeth, Pariapuria can actually rip apart large prey very easily. Pariapuria doesn't even really chew its prey and just swallows it up without a second thought. Pariapuria even swallows up things while just charging at foes. From this behavior, the Guild is also known for calling Pariapuria the Swallowing Wyvern.
    • Hunters may use its appetite against it.
  • Between its throat is an organ that stores some of the things it has swallowed temporarily for later. Its stomach does eventually inflate when it has eaten more than it can take in.
  • An inflated Pariapuria is vulnerable and sluggish. To get out of this vulnerable state it will vomit up whatever is inside its stomach to become both lighter and faster.
  • A Pariapuria's digestive juices is able to digest at a fast, violent rate with a foul smell. These juices even remain active after the Pariapuria has died and begins to digest the Pariapuria's body from the inside.
  • Parts of all sorts of creatures have been found inside its stomach from Rathian to Rajang parts along with ore and wood.
  • Its skin has moisture stick to it and a unique feel to it.
  • Pariapuria teeth have a foul smell, showing their bad hygiene.
  • Their fins are slimy.
  • Cartilage from a Pariapuria has good elasticity and resistant to degradation.
  • A Pariapuria's liver is small. It is a strong organ that continues to operate without any poisons inside of it. The poisons of prey are vomited out of its body.
  • Supremacy Pariapuria is a Pariapuria that has aged very little compared to a HC Pariapuria.

Dyuragaua

  • Dyuragaua is based on a Japanese Fox Spirit, Kitsune. Its face resembles one and is very fox-like in appearance.
  • They weren't seen very much due to them being very wary of people though they were finally confirmed after a long time.
  • Dyuragaua are very aggressive and extremely ferocious. They have even been seen attacking Berukyurosu.
  • Most of them have been seen in the Towers though some rarely actually have been found living in the Gorge and Highlands. This suggests that they can fly great distances to other areas.
    • There are no sightings of them in colder areas.
  • At first glance, it looks like they don't have wings but they actually have wings though they rarely fly.
  • Dyuragaua has some of the coldest ice breath and
    • Its stronger and colder with older individuals.
  • Dyuragaua has a Sleep Sac leading to its tail. Dyuragaua has pores releasing it only in Rage Mode.

  • A few Dyuragaua have faced-off against Mi-Rus.
  • The horns on them are extremely cold to the touch.
  • Its tail has multiple barbs on them and isn't filled with a toxic venom.

Mi Ru

  • They are rarer than Dyuragaura and were treated as an unconfirmed monster from lack of sightings previously but it was recently confirmed to be similar Dyuragaura and in the Rex Family. It also, later on, got known as the Black Fox Wyvern and G-Rank Unknown though later on it soon got an actual name, Mi Ru.
  • It has similar fluids to that of Akura Vashimu and Akura Jebia crystals and is used similarly to them but also differently. The crystals reduce the stamina of prey and will explode after a set amount of time.
  • The fire it breaths is strongly similar to the UNKNOWN(Black Flying Wyvern).
  • Mi Ru changes into its different forms by muscle contraction, changing of crystals, and changing the body. It changes to its different forms to face of against different threats that require different approaches. When it changes, its color changes, roar, eyes etc. all change.
  • Mi Ru's ecology is very mysterious compared to most other wyverns but it still isn't as mysterious as the UNKNOWN (Black Flying Wyvern).
  • Limited number of hunters are able to actually hunt Mi Ru from how dangerous and rare it is.
  • Its scales are smooth and are at their best at night. They disappear into the darkness of night.
  • The horns are filled with the crystal fluids.
  • Their sharp hairs are like needles and protect it from attacks on the back or from above.

  • From the crystal's fluids flowing through its body, Mi Ru actually can fight off many poisons such as Paralysis quite quickly.
  • Mi Ru's blood contains unknown components different from other monsters that seem to allow it to change into its many different forms.
  • Mi Ru is also based on Kitsune but is based of a shape-shifting spirit version of those fox spirits.

Nargacuga

  • Nargacuga has many unusual traits not usually found on a Flying Wyvern.
  • Before it was discovered by the Guild, it was seen in a few areas in the past and was only treated as a rumor. It was called Nargacuga in those areas so the Guild just went with that name.
  • The Nargacuga are aggressive and cunning.
  • Their wing blades and claws can cut through Pitfall Traps with ease.
  • A Nargacuga's speed and agility is far better than your basic Fanged Beast.
  • The reason why they don't have a shell is because, with these hairs, their a lot more agile, and don't have to worry about being slowed down by their shell like some other Wyverns.
  • Nothing really compares to their overwhelming speed and agility but most likely other Flying Wyverns.
  • Nargacuga ambush prey by hiding in the shadows or in trees at night before attacking. They've even attacked Guild Knights before and nearly killed them all. They prefer attacking their prey from their blind spots to catch them off guard.
  • Even if the first blow doesn't kill the prey, it will constantly attack its prey until its dead.
  • They have very good hearing, listening for the slightest sound.
  • Nargacuga can't fly very well so they actually glide. The wings, however, are used as a tool to cut down trees and foliage in its way.
  • The Nargacuga's main weapon is its tail. The tail is half of its length and strong enough to break the bone of large monsters in some cases.
  • When its eyes glow red, its blood vessels and a kind of mimicry.
  • While enraged, it really doesn't think very well and loses focus while attacking.
  • Turns out in old times, the people that lived in the Great Forest depended on Nargacuga materials for some of their needs. Their armor was called Hunters of the Night and sometimes People of the Great Forest. Without them, the Guild wouldn't have ever discovered Nargacuga.

Frontier Series

  • In Mezeporta, Nargacuga has always appeared as a shadow or mirage, making it difficult to actually identify it.
  • The Nargacuga discovered in the Mezeporta district are something different.
    • It seems these Nargacuga are special individuals or a potential subspecies from the ones we've seen in the Main Series.
  • Unlike its cousin, this Nargacuga has poisonous spines on its tail.
  • Similar to Silverwind Nargacuga, the Nargacuga can send waves of wind. Unlike White Gale Nargacuga, this Nargacuga is able to do it with its wing blades.
  • By spinning around at high speeds, this Nargacuga can knock up dirt and use the dirt like a smoke screen before ambushing prey.

Silverwind Nargacuga

  • Silverwind Nargacuga are said to kill, without even touching their own shadow. They do this by shock waves, powerful winds, that can leave complicated cuts in prey. These cuts make prey bleed.
    • This is how Silverwind Nargacuga gets its title.
  • The spikes it flings from its tail is said to actually have more impact, increasing the chances of it not missing a target.
  • Interestingly, Silverwind Nargacuga has been reported since MHFU and MH3U.
  • On certain portions of Silverwind Nargacuga's body, it has grown white hair and scales.
  • Its white hairs and scales are light in weight, allowing them to move freely. From this, it allows Silverwind Nargacuga to strike prey with powerful waves of wind.
  • Compared to normal Nargacuga, Silverwind Nargacuga prefer to attack their prey from a distance.

Green Nargacuga

  • The Green Nargacuga is a subspecies.
  • They are larger than normal Nargacuga and a lot more agile than them.

  • It is unknown how its tailspin is able to knock prey out cold.
  • It mostly hunts during the day and hunts less at night.

Lucent Nargacuga

  • Lucent Nargacuga is able to disappear from both the moon and some help from the fog.
  • Its been confirmed that the Lucent Nargacuga can be found in the Great Forest just like the normal one.
  • The poison it uses is very toxic and it's unknown how it produces it, though it seems its poison is stored in its spikes.
  • Its tail is a lot stronger than the other two.
  • The scales, fangs, spikes, wing blades, and tails of all three are different in terms of power, coloration, and a whole lot more.

Barioth

  • Barioth has pretty high intelligence even by Wyvern standards.
  • Barioth prefer eating the internal organs of prey.
  • Male Barioth use their tusks as a display to females during mating season. The longer the tusks and the better they look, the higher chance of getting with a female. Males will actually invade the territory of females in order to mate with them, though its dangerous due to the female might actually not wanting anything to do with them. Females hide in a hidden place while pregnant and will give birth to 2-3 cubs. She leaves them in caves to help keep them safe from danger such as the elements.
  • The shell on them is very flexible yet still hard at the same time.
  • Their fur is a lot softer than a Nargacuga's fur.
  • Both it and Nargacuga are close relatives.
  • The way it produces its icy breath is interesting. A liquid in its body spat out when it sucks in air. When combined with moisture it forms a ice block. It spirals from the contraction from its lungs and ice sac, making its huge tornado breath.
  • The barbs on their wings are used as weapons while attacking with its wings.
  • Its flying abilities are far better than most other Flying Wyverns and even come close to the Raths.
  • Their shell is light and shockingly soft.

  • Sand Barioth are well-known for making huge sand storms in the Sandy Plains.
  • Very strong Sand Barioth are known to produce smaller tornadoes used to blind and kill prey while also for defense.
  • As most of you know, the Sand Barioth covers its face with blood, which seems to be used to cool the Sand Barioth down.
  • Their sacs to produce the tornadoes is different from their icy cousin's.
  • They make the giant tornadoes from lack of walls to jump off in the Sandy Plains.

Hyujikiki

  • It hasn't been confirmed if Hyujikiki is closely related to Barioth and Nargacuga but, it's very likely from its characteristics.
  • There are very few sightings of Hyujikiki though, they have been seen in the Desert and Highland.
  • This monster was put into G-Rank due to it not being known very-well and its now being researched.
    • It was also put into this rank from it being very hostile, cunning, and unpredictable.
  • The needles on its body are made by fats and oils in its body that make them.
  • It attacks enemies and prey with these needles to kill them.
  • Hyujikiki will sometimes coil themselves and harden their needles to protect themselves.
  • It has evolved these needles to counter the attacks from certain predators like Poborubarumu.
  • The needles may turn red due to blood flow.
  • When it truly feels that it may die, it will begin to produce a special toxic venom in its barbs that cause various different effects to hunters such as Paralysis, Sleep, and Poison.

    • The other two are Akantor, the Black God, and Odibatorasu, the Sand God.
  • It was going to be an Elder Dragon at first from its power being beyond any normal wyvern but was put into the Flying Wyvern from it fitting better with them.
  • Ukanlos causes massive avalanches by accident from eating the ice and snow in the area.
  • Ukanlos can be found living within the Snowy Mountains.
  • Its unknown how much damage it can do but its believed to be very destructive though it is feared that it'll pair up with Akantor and go on a rampage.

  • Odibatorasu exact size is unknown but its believed to be equal or greater than Akantor and Ukanlos.
  • They spend most of their time under the sand. From this, sightings of them are rare and they were at a time considered as a near myth.
  • It uses the sand around it to see and to get an understanding of what is going on in its environment, suggesting that they may not have good eyesight.

  • Its roars and some of its more powerful attacks cause sand waves to fly towards hunters.
  • The weight of its scales can withstand the pressure from the sand around it.
  • Its horn is seen as a symbol of anger.
  • Its claws are evolved for it to swim through sand, destroy rocks and boulders, and to swing waves of sand at threats.

Poborubarumu

  • Poborubarumu's ancestors first lived and flew in the skies of the Highland during ancient times. Due to the competition from other Flying Wyverns that began to appear in the Highland during their time, Poborubarumu were outcompeted by other Flying Wyverns and their numbers began to decrease drastically. They were in a losing war for survival to a point where they were at the brink of going extinction. Some Poborubarumu split apart from their flying relatives in the middle of those ancient times becoming the Poborubarumu we see now while their flying relatives went extinct from being outcompeted by other Flying Wyverns.
  • When the Guild was getting ready to investigate the Sky Corridor, reports of a new monster began to surface around the Highland. The monster was described to be quite big and to be making a lot of strange sounds up in the Highland. The monster was soon named by the Guild as Poborubarumu.
  • Poborubarumu gets the title, Creation Sound Wyvern , from the strange sounds it can play with its special organs. These organs are found on its head, tail, and wings and each one helps plays a song. The head produces the sound by breathing in air and breathing out air through a hole above its head, producing strange sounds from it. The wings produce sound by vibrations through opening and closing them. Usually under the Poborubarumu's tail is a large hollow parasite. Both Poborubarumu and this hollow parasite have a symbiotic relationship with each other. The parasite is used like a drum by Poborubarumu as both as a weapon and as a tool.
  • The sounds Poborubarumu plays can confuse hunters and make hunters lose their mind by just hearing the sounds. These sounds can also somehow accelerate the healing of injuries for the Poborubarumu while also making their attacks and their body stronger, even doing the same to nearby hunters. This all seems to be done by bubbling water it uses to repair some injuries in a matter of seconds. While using the water, its slimy body fluids will change the color of the water into a variety of different colors.
  • Poborubarumu are powerful omnivores that will eat anything that they can fit into their huge mouths. Most of the time, smaller monsters will leave an area altogether to avoid being eaten by a Poborubarumu or will leave due to its horrible sounds.
    • Hunters mostly get requests to hunt them down due to its horrible music.
  • Poborubarumu are hostile Flying Wyverns that will fight with other large monsters like Gurenzeburu and Hyukiki to keep their territory or to gain better territories. Some monsters have even evolved ways to protect themselves from such attacks. Hyujikiki, for example, have specifically evolved their spines to protect themselves from attacks from Poborubarumu.
  • Inside their mouth are many rows of sharp teeth used for tearing apart prey. When an old tooth falls out their mouth, another one is waiting behind it to replace it.
  • Their bone marrow is strong yet also edible.
  • Their skin is good at holding warmth, has slimy body fluids on it, and has good durability.
  • Poborubarumu wings are similar to chords on an instrument.
