The Revenant Rex is a rare variant carnivore found in corrupted zones. It is carried by Tusoteuthis, enabling unique aerial transport strategies in combat zones. This creature is primarily used in offensive operations due to its high damage output and structural destruction capability.
It cannot be tamed or bred, existing solely as a hostile encounter.
