Amy Rose
Cream, a prominent character in the series, has a Chao named Cheese as a partner. In a move to keep her image safe, she often uses him to attack enemies instead of doing so herself. Other notable Chao include Chaos, guardian of the Chao, who serves as an antagonist in "Sonic Adventure"; Omochao, a robotic Chao who appears in several games as a means of player tutorial; and Chocola, Cheese's twin whom Cream, Amy Rose, and Big the Cat search for over the course of "Sonic Heroes".
