kenjilee92 That was Kazuya's rage drive. He only has access to the move when he's on low health. Rage drives are essentially really op moves that are usually safe, do lots of damage or extend combos and can change the tide of a round. Kazuya's has the added benefit of transforming him into devil form which changes the attributes of his moves until the end of the round if the opponent doesn't die to it. An example of how devil mode changes his moves is the ewgf, the electric punch he's always throwing out changes from being a high hitting move to a mid hitting one and so the ducking that devil Jin is doing to avoid normal ewgf's becomes useless. He also gets wings and lasers and shit just like devil jin.
