The Psycho Vanish is one of M. Bison's special attacks. It was introduced in the SNK vs. Capcom series, appearing in Capcom vs. SNK and Capcom vs. SNK 2. Its last appearance was in Capcom Fighting Evolution.
When activating a Custom Combo in A-Groove, Bison is able to carry the opponent to the corner and spam this move for maximum damage. Many have dubbed this "Painting the Fence."
