Oni

Oniis a secret character in the Street Fighter series, seemingly based on Akuma. A new variant of Shin Akuma is present in Super Street Fighter IV Arcade Edition. Known only as "Oni", this version of Akuma possesses longer white hair and darkened blue skin, with lumps on his forehead that appear to be the early stage of horns. Leaked images of upcoming DLC Achievements for the Xbox 360 version of Super Street Fighter IV indicate that he will take the form of a new secret boss in Arcade Mode, as well as being a playable character. This "ultimate" form allows Oni to use an air dash and grants him new attacks such as a forward teleport which slashes at the oppoent as Oni passes.

Oni appears to possess an air dash attack, the direction of which is determined by the punch button pressed. He also possesses a dashing slash which allows him to pass the opponent by, similar to his Ashura Senku. He also possesses a jumping smash attack which has been compared to Honda's Sumo Smash. It also appears that he no longer possesses his Hyakkishu attack.

His Super Combo, the Raging Demon, remains intact, but his Ultra Combos are new and appear to be based on Super Arts from Street Fighter III: 3rd Strike.
