A Smash Ball is an item that can be found in the Super Smash Bros. franchise. It is one of the most powerful items.
Smash Balls are rainbow-coloured orbs. They closely resemble the Super Smash Bros. franchise's logo. When someone breaks their outer crust, the Smash Balls shatter. The person who opened them will gain a powerful Final Smash. There is also a fake variation whose powerful energy rushes outward in a Supernova-esque explosion when it is broken.
Smash Balls first appear in Super Smash Bros. Brawl. They float around the stage randomly, but can suffer knockback. When their outer layer is broken, the Smash Ball's opener will start to glow rainbow and can unleash a powerful Final Smash.
