Executed by charging backward, then pressing forward and kick, M. Bison performs a forward somersault with his legs outstretched, kicking the opponent up to twice and aiming to land on the opponent's knees. However, in all of his appearances, a contridicting knockdown effect occurs on hit. The distance and speed at which it travels depends on the strength of the kick.
The EX Special version introduced in Street Fighter IV has a much faster startup and goes farther; its second kick hits twice and knocks the opponent even further away. In Street Fighter X Tekken, M. Bison instead performs a variant of the Knee Press Nightmare. Similarly in Street Fighter V the EX version will perform an attack similar to the Knee Press Nightmare from the Capcom vs. SNK series where Bison kicks his opponent twice before pushing off with both feet and slamming his foe to the ground.
The move is generally unsafe on block, as it may leave Bison open. However, when properly spaced to land only one hit, they can be quite safe and useful in pindown strategies. They also are quite useful for scoring knockdowns if the opponent tries to counter standing kicks or do low attacks, and has some (limited) use as an anti-air.
