Rex

Rex is a recurring enemy in the ' series that first appeared in '.

Character description
Rexes are dinosaur-like dragons who mainly inhabit Dinosaur Land. They are indigo-to-violet with a nasal horn, fangs, and small dragon wings, though they are flightless. They also wear big red shoes, similar to Yoshi. A recurring trait with all Rexes is their compressible bodies, as their stature becomes flatter when jumped upon. Due to this, it generally takes two normal jumps instead of one to defeat a Rex, though it can otherwise be defeated in one hit through other means of attacking it.

In A Super Mario World
A Rex appears in the McLeodGaming cartoon A Super Mario World, where it briefly appears in the first episode as one of the monsters that Mario fights with the Master Sword. It briefly walks across the ground before being crushed by six Green Koopa Paratroopas who had been sliced with the Master Sword, killing it.
