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, another wearing a fedora can be found sleeping in the Deep Woods section of the Wooded Kingdom, and another wearing aviator goggles can be found in the Metro Kingdom. Only the one in the Cascade Kingdom can be captured, and unlike the other captures, it can only be controlled for a limited time, due to Cappy requiring a lot of effort to keep such a large creature captured. Once the time expires, the T-Rex disappears and goes back to sleep at its original point.

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.
