Agnaktor is a Leviathan introduced in Monster Hunter 3.

Physiology

Agnaktor is in many ways similar to Lagiacrus; both are quadrupedal Leviathans of similar size and body shape. It is noted for its remarkable ability to swim through lava and tunnel through solid volcanic rock (though the rock becomes far more liquid if you go a short distance down). Its body is covered in a lava-like armor which hardens when cooled and softens when heated. It has a drill-like beak which is lined with rows of needle-like teeth. 

The Agnaktor closely resembles the Uroktor in essentially every way; the only real differences are the size of the Agnaktor and its ability to get magma to stick to its body. Even the ability to fire blasts of fire are present on both, though the Agnaktor is capable of unleashing a coherent beam. 

Abilities

Its fighting style is similar to that of other Leviathans. It can charge at a hunter and "swim" straight through solid rock in order to smash into them and produce a powerful orange beam, highly reminiscent of the one produced by Gravios. Its skin is coated in lava armor that is usually orange-red, indicating that it is heated and vulnerable, but if it goes too long without using its fire beam or being physically exposed to heat, the armor will cool, and become black and hard. In areas with physical ceilings, it may tunnel through the roof as well as the ground.

Behavior

Agnaktor are quite aggressive, challenging all others that encroach on its habitat, due to the fact that it has no natural predators at an adult age. The only threat that it encounters is if a monster challenges it for territory or food.

Habitat

Agnaktor is found exclusively in the Volcanoes and Volcanic Hollow of the Old World. It is highly adapted to life there, and is at home among the lava pits and rocky slopes. It does not stray from magma- and lava-filled areas.

Flash Bomb ★★☆ If a flash bomb is thrown in Agnaktor's face during its 360 fire beam, it will become stunned and will crawl out of the ground.
Sonic Bomb ★★☆ Works only when Agnaktor is burrowing through rock. Doesn't work when he's in Rage.
Dung Bomb ★★☆ Works just as well as on most monsters
Meat x ☆☆☆ Agnaktors, despite eating Rhenoplos, will ignore meat put on the ground.

Monster Hunter Portable 3rd
別名“炎戈竜”。硬い嘴と強靭な筋力を使って岩盤を突き破り、地中から地上、さらには天井までをも縦横無尽に行き交う。全身にまとう硬化した溶岩は非常に硬いが、地中に潜った際の熱や、火属性、爆発による攻撃などで赤く変化し、柔らかくなるようだ。
Monster Hunter 3 Ultimate
Also known as fire-pike wyverns, Agnaktor use their tough beaks and great strength to burrow through rock. However, their hardened-lava armor becomes soft when they burrow underground or are attacked with fire or explosives.
Threat Level (危険度): ★★★★★
Monster Hunter Generations
Also known as fire-pike wyverns, Agnaktor use their tough beaks and great strength to burrow effortlessy through rock, and can even burrow into ceilings. Their hardened-lava armor becomes even harder when cooled forming an almost impenetrable armor.
Threat Level (危険度): ★★★★★
Monster Hunter Stories
Agnaktor use their tough beaks and powerful muscles to burrow into rock, moving freely through the earth.
Monster Hunter Stories 2: Wings of Ruin
Agnaktor use their tough beaks and powerful muscles to burrow through rock, moving freely through the earth. Their tough armor is actually made of molten magma, which coats their bodies and adheres to them as it cools down.

Notes

General Notes

  • The English name Agnaktor is a direct transliteration of the Japanese name Agunakotoru (アグナコトル), which likely derives from Agni (Hindu god of fire) and coatl (Nahuatl for "serpent").
  • When low on stamina, Agnaktor will fail to produce its Heat Beam.
    • It will either sleep or prey on a Rhenoplos in order to regain stamina.
  • Sonic Bombs will trap Agnaktor, much like Monoblos and Diablos. Tossing a Sonic Bomb instantly after it has successfully burrowed into the ground will trap it. Also, like the Monoblos and Diablos, it is immune to this effect during Rage Mode.
  • When a certain part of the Agnaktor is wounded, and the lava broken off, that part will not cause weapons to bounce as much, even if the Agnaktor's other body parts have hardened.
  • If a Flash Bomb is thrown in Agnaktor's face during its 360 fire beam, it will become stunned and will crawl out of the ground.
  • Agnaktor, and its subspecies, have the largest amount of body parts that can be broken. These include their beaks, chests,  fins, four legs (each one can be broken individually), and their tails (Broken, not severed). This adds up to eight total body parts broken, not including a severed tail.
  • Hitting Agnaktor with a fire-elemental weapon or projectile will make its hardened armor soften up.
  • Agnaktor's roar requires Earplugs to block.
  • Some of Agnaktor's physical attacks resemble those of fellow Leviathan Lagiacrus, such as the slide, tail spin, hip check, double bite, and body slam.
  • Agnaktor was voted 92nd place in the Hunters' Choice for Top Monster during Monster Hunter's 20th Anniversary.[1]

Monster Hunter 3

  • Any form of explosive damage (from Barrel Bombs to Gunlance shells/Wyvern's Fire) will heat up Agnaktor's hardened parts, making them soft again.
  • Agnaktor receives no damage from the Dragon element when armored, but it becomes its main weakness when its armor has been destroyed.
  • High-rank Agnaktor gains a sweeping heat beam while on land, but Agnaktor only sweeps it to right, making its left flank a relatively safe area.
  • While Agnaktor is underground and a large monster roars, it will affect the Agnaktor the same as a Sonic Bomb.

  • Monster Hunter 3 Ultimate

  • Agnaktor also has a new attack where it will do a singular break thrust into the ground.
  • At G-rank Agnaktor gains a new move in which it will do a singular thrust into the ground and then do two more singular thrusts while moving slowly to the right or left.

  • Monster Hunter Stories 2

  • Agnaktor can be fought, but cannot be a Monstie.
  • Agnaktor is a Speed type monster, starting all combat without lava.
    • Agnaktors turn to Power attacks when covered in lava, and Technical attacks when enraged.
  • Agnaktor has no part weaknesses until Molten Uppercut/Molten Cross is used, softening their body with lava. Unbroken parts will fully regain part health as well.
    • Small globs of lava show on their face in this state, but not the rest of the body unlike previous appearances.
