When performing Chaos Impact, Chaos jumps into the air and then strikes the ground with a punch on the way down, inflicting a large shock that triggers an earthquake to trip its opponents. In gameplay, using Chaos Impact unleashes tremors throughout the area that affects the opposing opponents no matter where they are, causing them to trip and be left dazed for a few seconds. If performed while climbing, the opponents will be knocked off the walls. However, if it is performed while the opponents are gliding or in the middle of a jump, it will have no effect.
Chaos Impact can only be performed by playing as Chaos in the game's two-player mode. To use it, the player must press / on the ground after collecting twenty Rings. To use it again, the player has to collect another twenty Rings.
