However, as the popularity of Avatar: The Last Airbender illustrates, that’s not the case. Take Aang for instance: the fate of the world may rest on his shoulders and he might have all four elemental powers, but he's still a normal kid with struggles of his own. He's conflicted as he tries to reconcile his age with his responsibility, his values to his duty, his identity as a 12-year-old air nomad to his identity as the Avatar. Because internal conflict tends to deal with universal themes and emotions experienced by all people, it's a powerful tool for making your protagonist feel real.
