Crash was identified by several unique distinguishing features that were the result of serving onboard the Dutchman. He had tendrils sprouting from one eye socket, and mandibles in place of a mouth. His right leg had been fused with a tentacle. He wielded a snaut of a sawfish as a sword and was known to wield a pulley in combat. Crash also had tube worms hanging like a Rastafarian hairdo.
After Davy Jones was killed, he along with other crewmembers returned to their human form.
