Masters absorbed the Orochi power in SNK VS Capcom:
Chaos, he became Violent Ken. This "evil" version of Ken was
inspired by Sennou Ken (which literally means 'brainwashed Ken' in Japanese),
who debuted in Street Fighter II: The Animated Movie where he is being
controlled by M.
Violent Ken uses purple flames in his Shoryuken, not unlike Akuma's.
