Star Punch is Little Mac's Final Smash in Super Smash Bros. Global Apocalypse. It is the signature move of Little Mac in the Punch-Out!! series. Once Little Mac obtains the Smash Ball, he will rush forward a bit, delivering an incredibly powerful punch that delivers 50% and knocks almost any opponent off stage, releasing stars in the process. When he punches the victim(s), he will do in in slow-motion and then he will fire them off stage. It works similarly to Marth's Critical Hit, only Little Mac doesn't move that much forward.
