Cheese (Sonic X)

Cheese is a Chao owned by Cream the Rabbit, hailing with her to Earth from an unnamed planet in a parallel dimension, where they travel in the Blue Typhoon in Season 3. He always follows Cream and the only word he can say is Chao.

Cheese is depicted as being strong for his small size; for example, he can hold relatively heavy objects like baseballs bats. Also, he can perform a powerful punching attack with Cream which can defeat some robots.

History
Cheese once became Cream's friend, and they partnered up with Sonic, Tails, Amy and Knuckles. Once they were kidnapped by Doctor Eggman in Chaos Control Freaks and Sonic tried to rescue them, only to have Chaos Control activate, sending them to Earth, and scatter the Chaos Emeralds across the planet. They were then imprisoned by G.U.N., but were rescued by Sonic and Tails.

After all of them joining up (with the exception of Knuckles, who went solo in Missile Wrist Rampage), they help battle Doctor Eggman whenever he caused trouble and havoc to the world and live with Christopher Thorndyke and the Thorndyke family. At the end of Season 2, Cheese and Cream go home, and later help Sonic, Cosmo and the rest of the gang battle the Metarex in Season 3. After Cosmo sacrifices herself, they fail to see Chris go home and declare war on Eggman.

Trivia

 * In the Japanese version of episode 39, during the actual end credits (they play during the episode as well) Cheese replaces Amy in the Hikaru Michi ending. During the episode as the credits are shown while Team Chaotix were recaping Sonic X, the ending song begins then it skips to Cheese.
