Aang, from "Avatar: The Last Airbender." Aang is always optimistic and cheerful, but he is not perfect and, like all pre-teens, does suffer from confusion and romantic desires. He gets scared and feels overwhelmed by the task he has been assigned, and has even tried to run away from his problems. This is not your standard overly-macho hero. This is your average kid who's been given super-powers and told to beat up the baddest man around.
