Most of the time, Chopper is a toddler-sized human/reindeer hybrid, but his Devil Fruit abilit allow him to change his appearance depending the situation. Chopper's left antler is braced at base by a metal plate because it was broken du his search for the Amiudake when he was young He usually wears a large pale red/pink fuzzy top hat with a sideways medical cross (given to him Hiluluk) and a maroon pair of shorts. He also sometimes wears a blue backpack that has the same sideways medical cross as his hat. He also has a remarkable blue nose.
After the two-year timeskip, Chopper wears a new blue cap that has ring of dots around the circle, while the cap has buckles hanging from it. He wears this over his old pink hat. He also wears a white and yellow vertical-striped tank top and a orange pair of shorts.
Despite his involvement with his fellow crew members in Enies Lobby and defeating Kumadori of the CP9, Chopper is mistaken for a pet due to his normal size and appearance. Therefore, he is not considered much of a threat to the World Government, and was given a measly 50 bounty.
Chopper's dream is to become a great doctor that can cure any disease, much like his father figure Dr. Hiluluk's ambition, as well as to travel across the world, exploring with his friends, and expanding his horizons.
Chopper's hybrid (half-man, half-reindeer) form has a lighter fur tone compared to two years ago, and in his animal form he appears as a fully grown reindeer. Another change is that he is wearing some kind of helmet over his hat, giving him the appearance of wearing an oversized baseball cap. He developed a new form named Kung Fu Point, and has reinforced his Horn Point, his Guard Point has grown dramatically in size and his Heavy Point has a greater amount of muscles and fur. All of his 7 transformation points have been renewed and reinforced and he is able to freely transform into 6 of them without a Rumble Ball, requiring it only for the Monster Point form. He now has full control over his Monster Point, although he can only be in that state for three minutes before his body becomes weak for a couple hours as a side effect.
