Twelve character battle

A 12 character battle (often abbreviated to 12cb) is an arbitrary gamemode mostly played in the original Super Smash Bros. in which both players have access to every character in the roster once and battle until their last character.

12 character battles generally last 50-90 minutes

Ruleset

This is the most popular ruleset as popularized by Isai:

• First character is blind picked for both players
• Each character has 5 stocks
• Loser of each game picks next stage
• If loser changes stage, winner is given a chance to switch to any remaining character(s)

Trivia

• Many players prefer 12 character battles to main vs main battles as they believe it is a more accurate representation of who the better player is, based on their character versatility and matchup knowledge.
