These black-shelled Diablos are actually female Diablos in heat. The color signals their aggressiveness and heightened hostility to other creatures in their habitat.
- MHW Description

Black Diablos are female Flying Wyverns and a Subspecies of Diablos introduced in Monster Hunter G.


The designation as a subspecies is somewhat of a misnomer, as Black Diablos are simply female Diablos in heat. Their shell turns black during mating season to warn other monsters of their heightened aggression and hostility. It is not possible for a Black Diablos to be male.


Highly aggressive, even for such a large wyvern. Diablos are considered one of the most aggressive creatures in the Desert. Using the sand as cover, Diablos can launch devastating ambushes on intruders approaching their territory. Black Diablos behave like a normal Diablos while fighting. She is a highly territorial wyvern, and will attack members of their own species if they enter her territory, and they will also attack other monsters like the Tigrex should they approach.


Commonly found in Deserts. Black Diablos are well suited to arid climates, but her ability to tunnel in sand may limit her to deserts only. However in Monster Hunter 3 Ultimate, she can be found at the Deserted Island during times of extreme heat and drought in the Sandy Plains.

Hard Core (HC) Black Diablos

FrontierGen-HC Black Diablos Render 001.png

SR17+ required to hunt.

Unusual possibly mutated Black Diablos with bright blue eyes, purple flesh and mouth, more spikes all over its body and tail, large veins on wings, one horn very much larger than the other and increased muscle mass.

She has increased aggression, speed and strength able to make quakes that require Quake Resistance+2 skills just from her digging normally. This leaves many hunters instantly defenseless towards her digging attacks.

Her new attacks are fast and deadly including a new charge that is not horns to the ground first and unpredictable where it suddenly runs towards a target homing at high speed then hops landing horns first sticking them in the ground as it slides and then lifts its head and up very fast. This move is actually performed so fast it gives little time for hunters to use recovery items.

She has new behaviors when she charges normally as well such as ending her charge with a tail spin then double tail slam. Or a new tail attack shared with HC Monoblos where it slams her tail and uses its own tail weight to slides herself in the direction of her tail twice.

Another attack Shared with HC Monoblos is where the monster slams her chin on the ground making a strong quake requiring Quake Resistance+2 skills to ignore hoping to catch prey unable to move she instantly raises her head upward while sliding forward hitting all who was stunned by the quake.

Digging speed is increased to instant it digs into the ground it may begin chasing. And using a Sonic Bomb on the monster will instantly cause it to get enraged making sonic Bombs useless during its anger.

She is at SR100, one of the fastest of Diablos variations going at possible double speed in rage and repeating its already fast new charge attack and increased speed digging leaving very little time for hunters to use recovery items in the same room of the monster if faced alone.


General Notes

  • Throwing a Sonic Bomb while the Black Diablos is underground will trap it in the sand for a few seconds. However, this doesn't work when the creature is in Rage Mode.
  • Black Diablos' roar requires HG Earplugs to block.

Monster Hunter Freedom

  • Before it was confirmed in later sequels that Black Diablos are female Diablos in heat, in the description of the "Diablo Helm U" from Freedom 1 it refers to Black Diablos as a male.
    • "The black shell of Diablos. An honor worn only by those who have slayed him."

Monster Hunter Portable 3rd

  • Black Diablos returns, and can be fought in High-rank quests.
    • Black Diablos' attacks are the same as the common Diablos in the same game, but it catapults itself out of the ground more often than its ordinary counterpart.
    • Interestingly, some brown markings are visible on Black Diablos in P3rd, further supporting the idea that Black Diablos is a usual member of its species with color changes due to hormones.

Monster Hunter 3 Ultimate

  • Black Diablos can be hunted in the Moga Woods at night.
  • At G-rank Black Diablos can dig behind the hunter, using its tremors to stun them, before catapulting out of the ground at extreme speed.

Monster Hunter 4 Ultimate

  • Black Diablos's back can be broken.
  • After the underground launching attack, Black Diablos can do a 180 degree and charges at the hunter.
  • It can become infected by the Frenzy Virus.

Monster Hunter: World

  • Black Diablos has a new aimed charge that inflicts Stun on hit.
  • Black Diablos can have Turf Wars with Rathian, Pink Rathian, and regular Diablos. It wins against the first two and the latter's winner is randomly decided.
    • While the regular Diablos gets a Turf War with the update added Deviljho, Black Diablos cannot enter a Turf War with it.

Monster Hunter World: Iceborne

  • Black Diablos gains a new rapid charge which is signaled by a roar that can only be blocked with the skill Guard Up and a new combo that will make her dig underground after a charge repeatedly.
  • The monster now has turf war with Savage Deviljho, Fulgur Anjanath and Glavenus.

Monster Hunter Frontier

  • Black Diablos can be kept as a pet. Along with eating cacti, it is known to love eating Yale Nuts found in the Gorge and Tower, along with the rare Dosubisukasu flower (also from the Tower).
