Co-Op Event 21: The True All-Star Battle
The True All-Star Battle (ホントのオールスター戦, The REAL All-Star Battle) is the 21st and last co-op event match out of a total of 21 in Super Smash Bros. Brawl. In this event, the player has to KO the entire playable cast (minimum all 35 characters) in Brawl. The cast is fought in order of which Smash game they appeared in and whether or not they're secret. Samus or Zero Suit Samus will appear (they are still fought in the same order), Zelda or Sheik will be fought, and the Pokémon Trainer will only fight with one Pokémon. Both players have one stock and if one player gets KO'd, the other player can still continue until being KO'd or completing the event. As would be expected, the opponents are at a lower handicap than the players and are particularly vulnerable to attacks with high base knockback.
