Cheese the Chao
Cheese(チーズ, Chīzu?) is a neutral, sky-blue Chao with a red bowtie. Although Cheese's origins is never clearly mentioned, Sonic Heroes does reveal it has a sibling name Chocola the Chao. Cheese is also the best friend of Cream the Rabbit; whom he is always seen with. The most distinct aspect about Cheese is its ability to effectively damage foes when Cream uses him as her method of attacking. In Sonic Advance 3, Cheese displays the ability to transform into a Chao variant of Sonic, Tails, Amy, and Knuckles when the relevant character uses the tag-team action. His offensive capabilities continues to be a prominent factor in Cream's move-set in the following games. Although it only says, "Chao!", Cream can understand and translate what Cheese is saying. Since it is constantly by Cream's side, Cheese also first debuted in Sonic Advance 2. In Sonic Chronicles: The Dark Brotherhood, Cheese also increases the Luck of all team members.
