Chopper Tony Tony

Tony Tony Chopper is a main character in ONE PIECE, a reindeer who serves as the Straw Hat Pirates' doctor. After eating the Hito Hito no Mi, or Human-Human Fruit, he gained the ability to speak, think, and transform toward human form. Chopper is childlike and trusting but also a loyal companion with a serious interest in medicine. Past mistreatment left him wary of humans, though life with the crew gives him people to admire and imitate as he tries to define who he is.
