Oni is basically if the last of Akuma's mind and soul were 100% consumed by the Satsui no Hado. Akuma's never reached that state in the entirety of the series from Alpha to the III series.

The form's a What-If? that the developers thought would make a cool playable character and that's about all Oni amounts to.
