About these Brawl Stars moves: Brawl Stars uses on-screen game controls rather than fighting-game command strings. The entries below preserve the searchable move and ability names while showing each brawler's Main Attack, Super, Gadgets, Star Powers, Hypercharges, Buffies and Gears. Buffies are additional upgrades; choose the appropriate Gadget and Star Power rather than treating both options as active together.
