Flame Tigrex is like its adaptive relative but with cooled lava covering its face and claws. Unlike Tigrex, Flame Tigrex has red eyes and red stripes instead of both being blue.
Flame Tigrex has the same move sets as its relatives Tigrex. However, unlike its relative, Flame Tigrex is capable of breathing a fire beam that can cause the cooled lava on its head to heat up. Unfortunately, Flame Tigrex must cool down from doing this attack which can leave it open for hunters to attack it.
Flame Tigrex can roar like an enraged Brute Tigrex, when either in its Rage Mode or not.
Like Grimclaw Tigrex, Flame Tigrex will sometimes slam its claws on the ground to make shockwaves.
Flame Tigrex only lives in the Ghost Rune Volcanoes.
