Punch Attack

The Punch Attack, also simply known as Punch, is one of the signature moves of Knuckles the Echidna. It first appeared in Sonic Adventure and has since then been one of Knuckles basic moves in all the major games in the Sonic series where Knuckles is playable. It is a basic triple punch combo Knuckles delivers to his opponents.

Usage
When using the Punch Attack, Knuckles must stand firmly on the ground. He then punches his opponent in front of him with his fists up to three times in a successive combo attack. This is done in gameplay by pressing the Action Button three times in succession. The performance of the combo slightly differs from each game. It usually follows a quick one-two jab, followed by a third, more powerful strike.
