Wings of Icarus
From the Super Mario Wiki
Wings of Icarus is Pit's up special move in Super Smash Bros. Brawl. It is most likely a reference to both the Wings of Pegasus, one of the Three Sacred Treasures from the original Kid Icarus, and the Angel's Feather, an item from the same game that gives Pit temporary flight. When used, Pit's wings turn blue, and the player is able to fly freely for a limited time. The move gives Pit extra height when used from on the ground, also pushing away nearby opponents and items.
