When performing the Double Punch, Chaos 2 stretches its arms forward for a devastating attack. While the move is being performed, its fists glow.
In gameplay, the Double Punch is used during the Chaos 2 boss battle. The move can extend out into the air and hit Knuckles the Echidna even while Gliding, making caution a must. After using this move, Chaos 2 will remain in place for some time, giving the player an opening to attack it.
