Matrum uses its four massive arms to pummel prey into submission before devouring them. It actively refuses to eat anything it hasn't properly punched beforehand, even a treat from its Trainer.

Thanks to its gargantuan jaws, which could shred thick metal plates as if they were paper, it was invincible in the ancient world it once inhabited. It is impossible to defend against punches and chops doled out by its four arms.
