A massive species with four powerful arms, the average Petromand(Petrosapien + Tetramand) is 11 to 13 feet tall with a red thick diamond like skin. Built for battle, Petromands can take huge amounts of punishment as well as they can dish it out.
Their diamond-hard bodies make these fearsome warriors incredibly tough. Shards of the razor-sharp crystals jut out at numerous odd angles from their heads and bodies, discouraging physical contact, and also act as powerful weapons that can turn a car into confetti in a matter of seconds.
Diamondarms is also the name Simien gave to Allen's Petromand form, who is exactly the same form as this one.
