Figured I'd give you some insight on Dark Pit. Dark Pit is a clone of, you guessed it, Pit. His weapon of choice is the Silver Bow, which doubles as a dual-bladed weapon. He's a wild card; one game he's independent and works alone, the next game (Smash 4) he's working for the Forces of Nature.
He can also be qualified as a Blood Knight; he fights for the sake of fighting, and enjoys it.
