Mode Change is a move available to Ryu in Marvel vs. Capcom. Because of this ability, he is often referred to as Complete Change Ryu by players.
DescriptionEditExecuted by performing a half-circle back motion and pressing any punch button, Ryu's moveset changes to that of the corresponding character at the use of one full Hyper Combo Gauge. If medium punch is pressed, his moveset changes to that of Ken's; if heavy punch is pressed, his moveset changes to Akuma's; and if light punch is pressed, he will change back to his normal moveset.
The currently active moveset is displayed by the color of his costume, with red signifying Ken, and black signifying Akuma. Interestingly, Ryu's costume while using Akuma's moveset is similar in appearance to Evil Ryu circa Street Fighter Alpha 3.
