Psycho Crusher

From the Street Fighter Wiki

Psycho Crusher is M. Bison's signature attack in all of his apperances in the Street Fighter series of game and comics/mangas. M. Bison charges his right hand with psycho power, then surrounds himself with psycho energy while charging at his opponents, similar to a torpedo, which he resembles. This attack is initiated by walking backwards for 2 seconds, then forward and any punch. There is a super special version of this move which does a great deal of damage. There is also an ultra special version where Bison disappears and comes from off-screen and the entire screen is completly covered with psycho energy. It does a large amount of damage (more than half of your health is depleted.) In some of the mangas, Psycho Crusher is a "one-hit kill." Psycho Crusher is an equivalent of an output of 40 grams of Psycho energy.
