Cheese the Chao is a fictional character in the Sonic the Hedgehog video game series. He is the pet Chao of Cream the Rabbit and is often used as a method of attack by Cream in some games. Cheese is a neutral Chao with a red bow tie. Cheese measures 40 cm (1ft and 3in). It has the appearance of a Neutral Child Chao: It is light blue and has yellow accents at the tip of its head, hands, feet and tail, bulb-shaped head, dark blue eyes, a floating, yellow pom-pom ball hovering above the tip-top of its head that changes appearance corresponding to its emotions, two pink butterfly-like wings and a small circular tail. It is distinguishable from normal Neutral child Chao by his red / pink bow tie. (Its colour varies depending on the game played.) Its brother is Chocola Chao, who only appears in Sonic Heroes. He is also a Neutral Child Chao, but is chocolate brown where Cheese is light blue.
It is a Unique Chao in Sonic Chronicles: The Dark Brotherhood, and raises the entire team's luck when bonded to a character. Cheese is the only Chao in the game that can't be attained from an egg, and is also the only Chao that has significance in a side-quest. There is another obtainable Chao named Cheezlet that looks exactly like Cheese, but is smaller and has no bow tie.
Cheese is Cream's main form of attack - Cream launches Cheese as a 'homing missile' of sorts, as it homes in on and, in the Advance games, destroys an enemy, making it a valuable weapon. It is also shown to be able to create tornadoes in Sonic Battle.
Cheese also has the ability to change into a Chao version of Sonic, Knuckles, Tails, and Amy. This is only seen in Sonic Advance 3, and only Cheese has been shown to have this ability.
In Sonic Chronicles: The Dark Brotherhood, Cheese has the ability to greatly increase the luck of all team members during battle.
