Dark Pit (USBIV)

Dark Pit is an unlockable playable character in Ultra Smash Bros. IV and makes his second appearance in the series since Smash 4. He was confirmed at March 2015, the month that Kid Icarus: Uprising was released alongside with Pit, Palutena and Medusa, the newcomer. In the Kid Icarus series, Dark Pit is known to be a doppelganger of Pit in Kid Icarus. Basically, Dark Pit's costume origin was Pit's dark costume in Brawl.
Dark Pit is known to be a half semi-clone of Pit. Comparing to these two, their moveset are almost identical. The major changes is based on knockback, power and combo-potential. Dark Pit is a great surviver at high percantage. His knockback attacks are stronger than Pit, including the amount of damage and power. His problem is his combo potential that is not good as Pit.
Dark Pit's voiceclips are reused from Smash 4, voiced by Antony Del Rio, who also voices Pit. Unlike Pit, Del Rio speaks more rougher and darker due to his personality.
Dark Pit ranks the 71th place of the 103rd in the tier list, putting him at the mid tier classement (C+) behind Melia and after Olimar. This is a marginal rise for Dark Pit being a mid tier character in Smash 4, tied with Pit and risen a few stairs above in the tier list. This is also the first time that Dark Pit gets separated from even places of Pit.
