Oni
By mastering the Satsui no Hado, the man has become consumed by it. His mind is gone, and his body has been transformed into something that is incapable of being called human. What was once the man's code of fighting only the strong has become a mad desire to destroy everything in his path. The Supreme Master of the Fist, Akuma, is no more. There is only Oni, a demon in the truest sense of the word.
In a nutshell
Oni is similar to Gouken in that his playstyle is unique from other Shoto characters. That, however, is where the similarities end. While Gouken is more suited to zoning other characters, Oni, being Akuma, is more flexible and has many rushdown and mixup tools at his disposal. He has no Ashura Warp or vortex to speak of, but his excellent normals and Demon Palm/Slash mixup more than make up for that. His ability to airdash also makes for some interesting setups, due to the fire portion of the dash being able to hit opponents. The key to success with Oni is learning which of his tools are best for certain situations.
