In-Game Information

MH4U-Molten Tigrex Icon

A rare Tigrex variant theorized to exsist after the discovery of claw marks and prints far larger than those of an ordinary Tigrex. With no confirmed first-hand sightings, its exsistence remains a matter of debate among hunters.


  • Order: Saurischia
  • Suborder: Wyvern Feet
  • Family: Rex

Molten Tigrex is a quadrupedal Flying Wyvern. It is a subspecies of Tigrex and the last living trace of an ancient species of Tigrex that went extinct. Now only their genes stand with these lost behemoths.

Habitat Range

So far this species of wyvern has only been seen inhabiting the Tower Summit located within the Great Forest.

Ecological Niche

Like its two relatives these wyverns are top predators in their environment. Species such as Aptonoth and other herbivores are common prey for the wyverns. While powerful the Molten Tigrex competes with other deadly predators such as Silver RathalosBerukyurosuMi Ru and Kushala Daora in the ruins of the Tower. But with its large size, strength, and devastating Blast Ailment at its side these wyverns can easily fight on par with the other predators in its environment.

Biological Adaptations

Due to the large amounts of oxygen in the Great Forest, Molten Tigrex are able to grow bigger than their relatives from a gene mutation caused by their environment. The Molten Tigrex has many of the same attributes of its relatives (powerful jaws, claws, etc.), but differs from them in that it is capable of using the powerful blast ailment. This ability is due to dead crimson scales that explode when covering an opponent, much like the scales of Teostra. The claws of these Tigrex are also capable of acting as flints to ignite the explosive powder even when charging at an enemy. This is due to the claws being metallic in nature. These Tigrex are also the largest of the species, which makes them slightly less agile than their relatives but more powerful when attacking. However, Molten Tigrex have a unique ability to make up for their lack of agility. When farther angered beyond usual, Molten Tigrex's muscles will be somewhat exposed from its shell and skin. It is able to spread scales more often and even move at very rapid speeds with immense power behind its attacks. This, however, makes Molten Tigrex weaker to attacks.


Molten Tigrex are highly aggressive predators that will relentlessly attack enemies whether they be other monsters or hunters. In fact this creature is so deadly and powerful that few hunters are allowed to even hunt it.
