Mobambi

Mobambi (モバンビー) is a character that appears in the third movie, probably the most annoying anime character you'll come across in your life. He is a young boy who is the sole human resident of the animal-inhabited Crown Island. His father, a zoologist, was killed by a pirate (later revealed to be Count Butler) and he was washed ashore where the animal king, Kirin Lion, took him in and raise Mobambi like his own son. Mobambi regrads Kirin Lion as a father figure. His best friend is Bellamy.

Years later, Kirin Lion had passed on and Mobambi believes Chopper, who fell from a cliff, to be their new animal king, thinking he fell from the heavens. Even though it is eventually revealed that Chopper was not to be the king, Mobambi tries to help him regardless, even when the other animals abandon Chopper. It is through this act that he is dubbed the new animal king of Crown Island when Butler is defeated.
