This is Ienzo, one of the main villians in KH:Keyblade War. Not Technically the true Ienzo, the youngest apprentice to Ansem the Wise. He was originally Kurai, a close friend of Kibou's. He turned to the darkness and became the heartless he is today. the heartless next to him is his true form as a heartless. It took me a while to get his look as a heartless right. Enjoy.
