When using the Punch, Chaos 0's hand lets out a long ranged punch to strike its foes.
In gameplay, this technique is used during the Chaos 0 boss battle. This is the first move Chaos will using during the fight. When Chaos 0 is about to use it, its hand will glow. The Punch itself is a straight punch that can easily be avoided by moving to the side. Afterward, Chaos will stand still, leaving itself open for an attack. If hit by this attack, the player will take damage.
The Flagpole Punch (ポールの上からのパンチ Pōru no Ue kara no Panchi?) is a variant of the Punch. Outside of Chaos standing on top a flag pole, the Punch itself has the same properties as before. Chaos will only utilize this move when it has one hit point remaining.
