Psycho Power

"Fear and respect... the supreme energy that is Psycho Power!"

- M. Bison in Street Fighter Alpha 3

Psycho Power (サイコパワー, Saiko Pawaa) is the name of a spiritual energy 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 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 by throwing away all the goodness, compassion, and humanity from his soul, Bison has gained a considerable amount of power. This enegy also grants him the ability to float, teleport, and control the minds of other beings, as seen with The Dolls. He can also regenerate via the Psycho Drive, and create a wormhole, as seen during Guile's rival battle in the Arcade Mode of Super Street Fighter IV. However, Psycho Power can exceed the limits of his 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, explaining his desire to capture Ryu. 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 more powerful with its use.

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 powers (if any), It is most likely that the Satsui no Hado is clearly another motivator for Bison to capture him (possibly possession his body).

An alternate form of Bison that uses the "maximum" Psycho Power 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.

Trivia

 * Gill's Psycho Headbutt shares the same naming scheme, though there is no evidence to suggest that it is nothing more than a coincidental occurrence.
 * Psycho Power is also the name given to SNK character Athena Asamiya's psychic abilities. This is referenced in SNK vs. Capcom: The Match of the Millennium, where Athena tells M. Bison that "Psycho Power's not for evil!" after she defeats him.
