Dark Pit

Dark Pit is a clone of Pit created after the destruction of the Mirror of Truth, in the events of Kid Icarus: Uprising. He serves as the game's anti-hero, being somewhat of a rival to Pit, and his personality is more serious and aggressive. His appearance is identical to Pit's, except with the dark coloring to his clothing, wings and hair. His character is probably based off the "fallen angel" coloration of Pit found in Super Smash Bros. Brawl, as both Kid Icarus: Uprising and Super Smash Bros. Brawl were made by Sora Ltd.

Dark Pit makes an appearance as an unlockable fighter in Super Smash Bros. for Nintendo 3DS / Wii U. His inclusion in the game was first hinted in the animated segment of the Palutena reveal trailer, where he flies onto the stage for a brief few seconds.

Trivia

 * Dark Pit is the only new fighter in Super Smash Bros for Nintendo 3DS/Wii U who didn't have a trailer that revealed him. However, at the end of Palutena's trailer, he is seen.
