Psycho Power

Psycho Power (サイコパワー, Saiko Pawaa) is the name of a power that is utilized by combatants in the Street Fighter series.

Description
Often termed as an evil, negative or psychotic energy, Psycho Power is most notably exploited by its best known user, M. Bison, who utilizes the Psycho Drive to channel it. Psycho Power has been described as the corrupted negative energy of Soul Power, a power demonstrated by Rose; this may be true, consdering Rose is the formation of Bison's expelled "positive" energy.

Through its use, Bison has gained a considerable amount of strength, including the ability to float, teleport, and control minds, as seen with The Dolls. He can also regenerate via Psycho Drive. However, the power can exceed the limits of Bison's body, as seen during the events of Street Fighter Alpha 3; the type of body he possesses also determine the "ceiling" of his power level. While he does not necessarily need the Psycho Drive to use Psycho Power (as it was destroyed before the events of Street Fighter II), he is considerably much stronger with it.

When dealing with Ryu in Street Fighter Alpha 3, Bison calls the power within Ryu "the ultimate form of Psycho Power"; though he does not further explain the connection between the two (if any), it may explain his desire to capture Ryu.

An alternate form of Bison that uses Psycho Power to its fullest extent appears in the non-canon Street Fighter EX 2; his abilities are significantly enhanced in this form, and he also demonstrates the ability to create duplicates of himself, as shown in his use of the Psycho Cannon in said game.
