Rex

A Rex is an enemy that first appeared in Super Mario World. It is a deep-blue dinosaur-like creature with wings that can't fly.

Games

Super Mario World

In Super Mario World, it was one of the first enemies encountered. It takes two stomps to defeat it. The first stomp will make it shorter and faster, and the second stomp will defeat it.

Mario & Luigi: Superstar Saga

In Mario & Luigi: Superstar Saga, they are found on Hoohoo Mountain with Beanies and Dry Bones. A jump will decrease its height, and a second will decrease it even more, making it easier to dodge.

Super Princess Peach

In Super Princess Peach, they created their first appearance in Fury Volcano. Rex will be flipped over if Peach stomps on it twice. Swinging Perry at one will take it outright. They had their own sub-species called Sad Rex.
