Cotton Candy Eater -> Tony Tony Chopper's storyChopper was originally a reindeer with the slight oddity of a blue nose
which caused other reindeer to treat him as an outcast
However, when the young reindeer ate the Hito Hito no Mi,
he was even more ostracized from his herd
Unfortunately for Chopper, his attempts at communicating with the humans on Drum Island proved disastrous, he was shot by villagers who mistook him for the Abominable Snowman.
Luckily, though, he was rescued by the quack Dr. Hiruluk who named him and took him in as his friend and 'assistant.' Although his deeds were of dubious medical value, Dr. Hiruluk became Chopper's role-model. Hiruluk taught Chopper his philosophy on life and his strong faith in the Jolly Roger as a symbol of strength against all odds.
Chopper, naturally distrustful of humans, was not pleased, especially given Luffy and Sanji's desire to cook and eat him. Chopper was originally abandoned by his family for being different, and being with humans was the same. Chopper's first friends (other than the people who raised him) were the Straw Hats, which opened him up to the world.
Chopper is naive and highly timid often acting as a child because he doesn't know any better. Chopper is more or less on a journey to define himself, seeing almost anyone on his team as a role model and in some cases, imitate their behavior, especially Usopp.
When Chopper recognizes someone needs medical attention he often will start to panic and scream for a doctor, just to realize that he is one. He would rather run and hide then fight, but becomes more courageous when others are there to support him.
Another one of Chopper's habits is his reverse cartoon peek, where he stands behind a wall or a doorway and peeks at people, trying not to be seen by them. Unfortunately he's not hiding his body behind the wall, as a result his body is visible and only one half of his face is hidden.
He is an upright friend and companion who will try anything to overcome a task given by his team. He still has a feeling of distrust for humans for his youth and will often outright insult and claim that compliments don't make him happy to a human who compliments him while obviously being happy about it (he starts to smile and also dances a little).
