Cyber Akuma is the final boss of Marvel Superheroes versus Street Fighter and is a unique transformation of the Street Fight villain known as Akuma, after being chosen by the Marvel supervillain known as Apocalypse to serve as the final obstacle for the heroes of both worlds.

As the name implies Cyber Akuma is a frightening prospect, the power of Akuma enhanced by Apocalypse's stolen Celestial technology into a force capable of taking on Marvel's greatest heroes as well as most of the Street Fighter cast, acting as the Horseman of Death.
