Tony Tony Chopper. The adorable, gullible, hilarious, and amazing (emergency food supply) monster-doctor of the StrawHat' crew. His dream is to become a great doctor, able to cure any disease. Carrying the knowledge of the great Dr. Kureha, and the dream of his father-figure, Dr. Hiluluk, Chopper travels the Grand Line to not only accomplish his dream, but also to help Luffy and the others accomplish theirs.
He's on his way to becoming the greatest doctor, but right now, he's also the proud "monster" of the StrawHat crew. He's one cool reindeer.
....and that doesn't make him happy, you bastards~!! XD
