Crex is one of the supporting antagonists in the 2002 animated Disney film, Treasure Planet.
He is an alien pirate in John Silver's crew who seems to be an orange anthropomorphic anglerfish with a "T-Rex" complexion. He was involved in the raid on the Benbow Inn, being one of the first two pirates (the other being Verne) to storm inside before Silver entered himself. It is unknown what had happened to Crex in the film, as his last appearance was sleeping at a campsite where he, Silver, and several of the other pirates were sleeping.
- "Come on."
- His name is based the name "Rex" from the largest carnivorous dinosaur, Tyrannosaurus Rex.
