Angel

Angel, also known as Warren Worthington III, is a young multi-millionaire who has a hard time adjusting to his mutation. He decided to become a lone vigilante, donning a costume and mask to perform heroic deeds in New York City, but stopped after his actions garnered negative attention from Magneto. Though he ultimately does not join the X-Men, he becomes allies with them. Eventually, Angel joins the X-Men in their concerted assault against Apocalypse, and in Xavier's glimpse of the future in the final episode, he's shown alongside the other X-Men. Angel's mutation is a pair of huge white wings that allow him to fly.
