All-Star Mode

In Super Smash Bros. Melee, All-Star Mode is an unlockable 1-player mode which pits the player up against every character in the game. The battles consist of a set amount of randomly picked characters teamed against the player, and the last fight is always against a team of 25 Mr. Game & Watches.

However, the player does not automatically regain health in between battles, with only way to heal being one of three Heart Containers available in between matches. These Heart Containers, unlike normal containers, heal the player up to 999% (restoring the player to 0%) instead of only healing 100% damage. However, if the player enters the portal while damage is being healed, then the damage will not heal any further, and the next match will start with the same amount of damage the player had when he or she entered the portal. The player can also absorb damage with Ness' PK Magnet and create food with Mr. Game & Watch's Judge. The player can also collect random trophies that sometimes appear after they finish a battle against another character or a team.

In order to unlock All-Star mode, one must unlock every character.

Super Smash Bros. Brawl
All Star Mode has returned in Brawl, and again needs to be unlocked. And its mostly the same except for a few details. You still get 3 Heart containers, random Trophies, and fight through every character in the game. You still only have 1 life, and you do not regain health between matches without a Heart container.

However, instead of the matches having a progressively large enemy team, the opponents are based by series. The highest count of enemies on the stage at a time is two. When a series has more than two opponents a new fighter will appear a few seconds after you KO one of the opponents. This means that stages for Kid Icarus, Ice Climbers, and  Pikmin will be easier than Mario , Legend of Zelda, and  Pokemon. In the case of Pokemon, there are a total of six opponent, as the Pokemon Trainer will send out each Pokemon separately.
