Violent Ken is an alternate evil form of Ken Masters, which mistakenly absorbed the Orochi power and thus became uncontrollable due to the Riot of Blood. He has red-glowing eyes, white hair and a more aggressive fighting stance. Reflecting his mid-boss status, he is very strong and fast, possessing the same moves as the regular Ken with the addition of a teleport-dash which allows him to dodge incoming attacks and move fast across the arena.
- Violent Ken was inspired by the Sennou Ken (Brainwashed Ken) from Street Fighter II: The Animated Movie, where Ken is brainwashed by M. Bison.
- The official artwork for the game shows Violent Ken sporting an afro, which is never seen on his in-game sprites and portraits.
