Tirraukronus is a large Brute Wyvern resembling a Tyrannosaurus.However, it has several differences, the most obvious one being the large crown-like crest on the top of its head. This crest is a shiny, metallic gold, and gives it an air of majesty. It is notable for its deep purple scutes and carapace, which have crimson accents on the tips and edges. It also has a band of crimson feathers on its neck which stretches across its back, giving it the illusion of a cape. Its tail has numerous ridges on its length, and ends in a small golden club that resembles the head of a scepter. Tirraukronus also has a different posture from most Brute Wyverns, taking regal, measured strides rather than lumbering.


Tirraukronus have an amazingly strong bite force, eclipsing even that of Deviljho's. This bite can crush carapaces and bone like mere sheets of paper, and its roar is comparable in volume and power to that of a Brute Tigrex's. Tirraukronus is also capable of breathing out mysterious crimson flames that contain the Dragon element,.


High Rank

Tyrant's Roar: Upon seeing a hunter, Tirraukronus will raise its head to the sky and roar extremely loudly. This roar deals damage to hunters that are too close and requires HG Earplugs to block.

Stomp: Tirraukronus raisesa foot, looks below it, and stomps down.

Stun Roar: In a manner similar to Brute Tigrex, Tirraukronus bends down in front of a hunter and roars loudly. This roar does not require Earplugs, but it inflicts Stun.

Triple Bite: Tirraukronus bites forward three times.

Advancing Bite: The monster winds up, then bites down while stepping forward.

Crushing Fang: Tirraukronus winds up before stepping forward, delivering a massive bite.

Jaw Lift: The monster sticks its lower jaw into the ground, then rushes forward while charging.

Forward Bite: The monster bites forward. Has medium damage and range.

Side Bite: A single weak bite to the side. Doesn't do much damage, but comes out very quickly.

Head Swing: The Brute Wyvern takes a step forward before lifting its head into the air diagonally, sending anyone in its way flying forward. This attack can cause Stun instantly if a hunter is hit by it and flies into a wall.

Hip Smash: Tirraukronus performs a hipcheck similar to Deviljho's. This can be followed by a Charge or a Stomp.

Charge: The monster sprints at a hunter at a surprisingly fast pace. Can be used either as an attack or as a way to close distance.

Tail Sweep: Tirraukronus sweeps its tail across the ground in a semicircle.

Enraged Only

Brute King's Rage: Upon entering rage mode, Tirraukronus will do something strange. Its face and jaws will begin to turn a bloody red, and flames of Dragon energy will begin to leak out of its mouth. It will then roar extremely loudly as it did at the beginning of the hunt, but this roar will now have a black coloration like Kushala's black wind barrier. This roar inflicts Dragonblight.

Draconic Residue: In Rage Mode, all of its roaring and biting attacks will inflict Dragonblight.

Draconic Flames: Tirraukronus breathes out a medium-sized cone of draconic energy that resembles a flamethrower. Causes Dragonblight.

Draconic Flame Sweep: The monster sweeps its flame breath in an arc that resembles Deviljho's breath attack. Causes Dragonblight.

Double Crushing Fang: The monster uses its Crushing Fang attack, then follows up with another one with almost no windup.

Scepter Swing: In a manner similar to Anjanath, the monster looks behind it and swings its tail behind it twice in an arc.


On Your Knees!: Tirraukronus's most powerful attack. To start it, it will suck in a large amount of air, like Brute Tigrex. It then releases all of the air in a massive roar that not only deals damage, but forces hunters to their knees so that they are forced to endure the whole attack.

Serve Me Or Die!: If a smaller monster is in the area, it will perform this attack. Tirraukronus will walk up to the smaller monster and roar in their face, terrifying them. There are two ways this attack can go from here.

  • If the monster chooses to "serve" Tirraukronus, they will submit to the Brute Wyvern out of fear. They will then cooperate with it to attack a hunter, and become more aggressive.
  • If not, Tirraukronus will descend upon the monster and attack it, killing it quickly. It then devours the monster's corpse to regain some of its health and stamina.

Enraged Only

Fit For A King!: Similar to Deviljho, the Tirrankronus pins a hunter under its foot and begins to bite at them.

Off With Their Head!: The Tirrankronus bites downward quickly and powerfully, attempting to catch a hunter in its jaws. If it suceeds, it will lift the hunter up and bite them a few times before spitting them down to the ground below. This attack can result in an OHKO if the hunter has low defense.

Biting Combo: The monster bites forward twice, then performs a semicircular tail spin.

Dragonfire: Tirraukronus breathes out a large blast of draconic energy that causes Dragonblight.

Habitat Range

Due to its adaptability, Tirraukronus can live almost anywhere. They have been seen inhabiting a variety of places, including arctic regions like the Frozen Cliffs and tropical areas like the Verdant Jungle.

Ecological Niche

Tirraukronus's size and power are more than enough to establish it as an apex predator wherever it decides to settle. The only monsters powerful enough to challenge it are other Tirraukronus, monsters on par with Elder Dragons such as the rare Deviljho and Rajang, and Elder Dragons themselves. They are known to regularly get into fights with creatures as large and ferocious as they are, such as the horned Behemoth Cerambus, the firebreathing Flying Wyvern Rathalos, and the armored Brute Wyvern Duramboros. These battles are partly because the local monsters aim to protect their territory, and partly because they want to avoid becoming food themselves: unlike Deviljho, the Tirraukronus prefers to eat larger, more well-armored prey. It can most often be found eating large Behemoths such as Cerambus, Brascieos, Mallearmus, and Tarrustah. They will also eat Carapaceons such as Daimyo Hermitaur and large predatory monsters, and occasionally eat members of their own species.

Biological Adaptations

Tirraukronus's main adaptations for survival are located in and on its head. Inside their mouths are large, jagged teeth designed to crush the hard shells and bones of prey. Their jaws have large muscles, giving them an extremely strong bite. Added plating around the jaws increases its already formidable bite force and protects its teeth from damage. They also have large lungs and broad chests which amplify their roars, a clubbed tail that can be used to bludgeon prey from a distance, and long legs that enable them to chase prey down over vast distances, but their most dangerous ability is their breath. When enraged they can breathe out mysterious crimson flames imbued with the Dragon element. In this state, they also become stronger, faster, and more aggressive, although their resistance to both normal and elemental damage declines.


Though not as voracious as Deviljho, Tirraukronus is still a highly aggressive and extremely dangerous apex predator. Not much is known about how they interact with each other or how they raise young, but it is believed that they are cannibalistic due to bite marks found on Tirraukronus carcasses that match the jaws of another Tirraukronus.

A Variant of Tirraukronus appearing in Monster Hunter Venture.


Tirraukronus by Nrex117 A fearsome Brute Wyvern with bone-crushing jaws and a powerful roar. Tirraukronus establishes itself as an apex predator wherever it goes, be it a scorching volcano or a frigid tundra. It competes with its distant relative, the Deviljho, for food and territory; and can be just as destructive to the ecosystem.

Tyrant's Arrival


  • When enraged, its face and jaws will turn blood red, and draconic flames will seep from its mouth.
  • When fatigued, it will begin to drool and its head will droop.
  • To recover stamina, Tirraukronus will either eat a carcass or kill an herbivore.
  • Tirraukronus's roar requires HG Earplugs to block.
  • Tirraukronus has a variant known as the Brutal Tirraukronus.
  • Tirraukronus's head can be wounded twice, its chest can be scarred, its back can be wounded, and its tail can be severed.


  • This monster was made to be a rival to Deviljho.
    • The two monsters are also made to represent two "halves" of Tyrannosaurus: Deviljho represents its raw aggression and savage hunger, while Tirraukronus represents its brutal power and image as a ruler.
  • Tirraukronus's name is derived from Tiran, the Russian word for tyrant; Paura, the Italian word for fear; Krone, the German word for crown; and Tyrannosaurus.
    • This is because Russia, Italy, and Germany were all ruled by tyrannical dictators in World War II.
  • Despite being a relative of Anjanath, it was actually conceptualized before Anjanath's reveal. It was retroactively decided to be related to the Anjanath because of their visual similarity.
