Boss Battles Mode

Boss Battles Mode is a Unlockable Stadium mode introduced in Super Smash Bros. Brawl, which is very similar to All-Star Mode, except you fight all bosses rather than all characters. Boss Battles Mode is unlocked after the player completes both Classic Mode and 'The Subspace Emissary' for the first time, or in other words, has faced each boss other than Crazy Hand at least once.

Gameplay
The goal of Boss Battles Mode is to defeat every boss in the game with a single stock, or two characters in its co-op mode. When a player begins Boss Battles mode, they are immediately dropped into combat against one of the ten bosses. Once a boss is defeated, the player is brought to the rest area. The rest area displays all defeated bosses as trophies, a screen that displays the face of next boss to be fought, and has three heart containers, or five in co-op mode, which, like in All-Star, do not reappear even upon later visits to the rest area. This format continues until all bosses are defeated. This format is the same as All-Star Mode. However, the player is not allowed to continue after losing their stock, as it is a stadium mode. The battles occur in random order, except for the battle with Tabuu which always occurs last. Each boss has their own Stamina Bar as one would normally fight them in the Subspace Emissary, including both of the Hands. The player is treated with a picture of one of the bosses upon completing Boss Battles: this picture varies depending on the difficulty level chosen. You may use stickers in Boss Battles.

The battles in this mode include:


 * Master Hand
 * Crazy Hand
 * Petey Piranha
 * Rayquaza
 * Porky
 * Galleom
 * Ridley
 * Duon
 * Meta Ridley
 * Tabuu

Tips
You're facing 10 bosses instead of one, and have 1 life instead of 4, so you can't give a frenzy of attacks at once. Wait for the gaps between attacks, then strike briefly, then prepare to evade the next attack. Strike a single multiple hit quick attack, then retreat to shoot projectiles if possible while evading the bosses' moves. You are given ten bosses to fight, and only 3 Heart Containers. Logically, it is best to use each one after every third Boss, when you are given a Trophy. But some bosses are hard to face with high damage, such as Duon or Porky, so use them when you feel you will be unable to beat the Boss otherwise. Moves like Rock Smash, Hammer, Yoshi's and Toon Link's Dairs and Bowser's Forward smash inflict tons of damage. Use them, as long as they don't make you vulnerable. Kill moves like Rest and Warlock Punch work well, but use them only if you know they will defeat the boss in that hit. Kill move lag will almost surely leave you open to an attack. The less time it takes to defeat a boss, the less chance there is you'll receive damage. The best moves to use are usually those that can score multiple hits. Fox, Ness, and Lucas are effective against Duon and Meta Ridley in that they have reflectors or absorbers. Pikachu is effective against any boss that takes to the air, as he can use Thunder to attack from the sky. Marth is effective against many bosses in that his Counter inflicts massive damage, as does Ike's. Some attacks like Knee Smash have very limited range and are hard to use in normal brawls. For bosses, though, it is very easy, in that you can simply be touching any part of the boss, which easily take up a quarter of the stage, to inflict damage. Even if it's on Easy mode, dodge as many attacks of bosses as possible. Some attacks of the bosses give you hints of what kind of attack it will be, and others come very quick. So dodge your way to attack without being wide open to be attacked at.
 * Play Conservative.

 * Easy ways to beat it on Intense
 * Play it on Co-op with another skilled player, and both use Charizard. Then use Rock Smash constantly on bosses, avoiding Tabuu's Off Waves with Pokemon Change or, if skilled enough, by rolling or sidestepping.
 * Play as Meta Knight and continuously spam Nair.
 * Play as Lucario and use Heart Containers only when reaching 250%+
 * Play as Ness or Lucas in order to heal with Master Hand's or Duon's energy blasts.

Boss changes from other modes
Several of the bosses are slightly altered from their appearances in other modes.
 * Crazy Hand is a boss itself, rather than together with Master Hand.
 * Master Hand and Crazy Hand have Stamina Bars like other bosses, rather than the usual HP shown at the bottom.
 * Galleom will be fought randomly in one of his two stages.
 * There is no time limit to fight Meta Ridley.
 * On Easy, Normal and Hard modes, Tabuu's Off Waves do not instantly kill a player who comes in contact with them.
 * In lower difficulties, all the bosses' speed, attack power and health are greatly decreased.
 * Petey Piranha's cages are empty, as when he is faced in The Great Maze stage of The Subspace Emissary.
 * The individual boss themes are replaced with generic music, Boss Battle, except for Master Hand, Crazy Hand and Tabuu. They use the music Final Destination (Melee), Giga Bowser (Melee), and Boss Battle Song 2, respectively.
 * Stickers can be used, although they only appear in The Subspace Emissary. However, if the player has equipped any stickers to a character, that character's bonuses, resistances, and attack boosts will still be intact.
 * Items do not appear.
 * Each time you defeat three bosses you earn a rare trophy.

Trivia

 * After you beat a boss, if you jump off the edge and go below the lower or side blast line, you will not be KO'ed.
