He's easy for the beginners. He'll start off with a taunt. Usually taunts glow yellow so they can give stars for the all-powerful Star Punch, so punch wherever is punchable. Punch his head to get a star. Glass Joe has only one part of his body blocked, so when his gloves are at his body, punch the head and when the gloves are at the head, punch the body. Otherwise, just dodge then attack. Glass Joe has a One-Hit Knock-Out spot. He'll step back and cheer for France and then step back into position. The time to hit him is when he steps back in his the spot, so be ready to time your attack.
