Final Bison is similar to regular M. Bison in terms of appearance. The most noticeable difference is the he emits far more of his purple Aura.
He is playable only in the console versions of Alpha 3, however, like Shin Akuma, he does not have his own slot on the character select screen and instead can be chosen by choosing regular M. Bison with the select button.
In Street Fighter V, M. Bison's has a Final Bison alternate costume, depicting him completely consumed by Psycho Power.
In Street Fighter Alpha 3, the player will face against Final Bison in the end of the single-player mode (except when playing as Bison himself, Balrog, Juni, or Juli, in which case Ryu will be the last opponent and Evil Ryu who fights Shin Akuma instead). Final Bison differs from the regular version of M. Bison, in which he uses a fighting style similar to X-ism dubbed Shadaloo-ism (or S-ism).
He has all of the special moves his regular self uses during S-ism, with more powerful basic moves and a new Super Combo dubbed the Final Psycho Crusher (instead of the Knee Press Nightmare his regular self uses during S-ism mode), which fills the whole screen with a devastating streak of blue flames. It is also much faster and stronger than its normal counterpart, cannot be blocked in the air, and inflicts severe block damage; it is the most powerful move in the game.
In the arcade version, the player is not allowed to continue after losing a match against Final Bison; instead, the game will play a bad ending. He also has a different theme song compared to his regular counterpart dubbed "Brave or Grave".
