Boss Battles Mode
Boss Battles Mode (also called Boss Battles, Boss Mode, Bosses Mode, Boss Rush, or Boss Rush Mode) is an unlockable Stadium mode introduced in Super Smash Bros. Brawl that is very similar to All-Star Mode, except the player fights all the bosses rather than all the playable 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 defeated each boss other than Crazy Hand at least once.
The goal of Boss Battles Mode is to defeat every boss in the game with a single stock. When a player begins Boss Battles Mode, they are immediately dropped into combat against one of the nine bosses not including Tabuu. 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, which, like in All-Star Mode, recover the player's damage to 0% and do not reappear upon later visits to the rest area. This format continues until all bosses are defeated. The bosses are fought in random order, except for Tabuu who is always last.
This format is mostly the same as All-Star Mode. However, the player is not allowed to continue after being KO'd and using up their stock, as it is a Stadium game. The final three bosses before Tabuu move and attack at a faster rate (most noticeable with Rayquaza and Galleom), and bosses have more HP the later they appear. The player is treated to a picture of one of the bosses upon completing boss battles; this picture varies depending on the difficulty level chosen. Stickers cannot be used in Boss Battles.
Boss Battles also includes a co-op mode (a mode that a player can get a second player to help them with single player mode games), where both characters will have a single stock and there will be two extra Heart Containers for a total of 5. Both players must remain alive; if either player loses their stock, the game ends.
The battles in this mode include:
There are eight trophies obtained by completing Challenges and one unlockable character in Super Smash Bros. Brawl involving boss battles mode. None of these challenges can be broken by a Golden Hammer; except in PAL versions of the game (which can break open all challenges).
Changes from other modes
Several of the bosses are slightly altered from their appearances in other modes.
