T-Rexaur possesses incredible Strength and is easily the strongest monster in the Balamb area. It is weak against Ice and the command ability Doom works as well. T-Rexaur is susceptible to Sleep and Blind. At higher levels T-Rexaur gains a special bite attack on characters if they use magic on it. If the player successfully uses the Devour command on a T-Rexaur of Level 40 or above, the devourer's Strength stat will be raised by one.
