Zuko ( Avatar: The Last Airbender )

Zuko is one of the first enemies that you'll meet first, at the very beginning. He's a firebender, and the son of Firelord Ozai and princess Ursa. Zuko has a sister who is very cruel and was the nearest to kill the avatar.

Three years later, after his mother dissappeared, Zuko's uncle allows a thirteen year old Zuko to enter a war meeting. Zuko, upon hearing of a general's plan to sacrifice novice troops in battle, speaks out in protest. Ozai demands Zuko duel in an Agni Kai, but when the duel begins, he finds himself dueling not the general, but Ozai himself. Zuko surrenders, unable to duel his own father. Ozai, seeing this as weakness and disrespect, scars Zuko, strips him of his birthright, and exiles him, under orders not to return unless he captured the Avatar.

After 3 years chasing the avatar, his father sends his sister Azula to kill him, but he managed to escape with uncle. He later betrayed his uncle, against his own will, in order to "kill" the avatar. After returing back home, his father welcomed him home, But he still knew the avatar was alive. Zuko appears as the enemy in both Avatar games. In the second you'll have to fight both Zuko and Azula. He has a bad character, i know that. But interesting too. In the third game, i think he will be your ally.
