T-Rex

The T-Rex is an enemy from Super Mario Odyssey that can be controlled by Cappy. It is based off of the real, and extinct.

One T-Rex can be found in the Cascade Kingdom, while another wearing a fedora can be found sleeping in the Deep Woods section of the Wooded Kingdom.

According to Kenta Motokura, the director of Super Mario Odyssey, the T-Rex's realistic design was influenced by Super Mario World, another game where Mario is alongside dinosaurs. The development team wanted to include a dinosaur never seen in a Mario game before in hopes of surprising the player, causing the developers to steer away from the more cartoonish and caricatured dinosaur designs used in Super Mario World.
