Archangel

Angel is a hero from the popular X-Men franchise, produced by Marvel Comics - he is a mutant named after his bird-like wings that are powerful enough to give him flight and he has a nature that is as kind and heroic as his namesake, ready to protect others from harm despite his rather difficult experiences in life.

Angel was temporarily transformed into the villainous Archangel by the X-Men's archenemy, Apocalypse, and fought against his former team-mates as a Horseman - however this was neither permanent nor by choice and Angel has since become a hero again and freed himself from Apocalypse's control.
