Riku

Riku is Sora's friend and former antagonist in KH. He ended up getting possessed by Xehanort after succumbing to darkness, but managed to break free from his spell and was able to take on the powers of darkness for good purposes. Chernabog and his son plan to drag Riku back into Darkness in order to provide Mirage with her own son to watch over. ( no picture please).
