Archangel, or Warren Worthington III, is one of those comic book characters who has gone through a lot of changes over the years. His original power was just having huge feathered wings and being able to fly. Which seems pretty good until 47,000 other mutants all come along with better powers than you. Some bad guy tore up his wings and in a convoluted series of events he ended up with razor-sharp metal ones instead. He complained about it a lot, but deep down I think even he knew they were a vast improvement.
