Bosses are distinctly more powerful and bigger in size than the regular playable characters. They have unique attacks and can only be defeated by depleting their stamina. There exists also minor battles with similarly powerful enemies but are to a lesser importance and defeating them does not mean the end of the game or level; this is called a mini-boss.
Some information regarding to Super Smash Flash 2 is still subjected to be changed.
Bosses and mini-bosses in Super Smash Flash
- Main article: Master Hand (Super Smash Flash)
Master Hand, as he is in the Super Smash Bros. series, is the final boss from Classic mode and Adventure mode in the original Super Smash Flash and is one of the only three bosses in said game. He is a hand-like entity described as the manifestation of the creative spirit and is considered the creator of the Super Smash Bros. world, this affirmation, however, is uncertain for the Super Smash Flash series given their fan-made status. Master Hand's stamina varies per difficulty and is always fought on Final Destination. Though Master Hand is big and getting hit by his incoming attacks is almost inevitable, pausing the game as he is attacking triggers a glitch that makes Master Hand's attack inoffensive.
- Main article: Crazy Hand (Super Smash Flash)
Crazy Hand is Master Hand's left counterpart and is also the final boss from Adventure Mode in SSF, where he fights alongside Master Hand after his stamina has depleted to the half and he is one of the three bosses in said game. As the inverse of Master Hand, he is described as the manifestation of the destructive spirit. It looks not so different to Master Hand, aside being the left hand, but it is evidently more erratic and moves a bit faster when attacking. Crazy Hand's attacks are also inevitable, but the exploiting same glitch specified above, means no harm to the player.
A giant Pokémon appears as a mini-boss which has to be faced at the end of stage 5: Pokémon Stadium from Adventure mode in SSF and it is one the three bosses and the only mini-boss in said game. It is an abnormally large Pokémon character whose attacks deal more damage, given the size of the hitbox is bigger than the regular sized Pokémon; but this also means it's hurtbox is bigger and it has no flinch resistance whatsoever. The Pokémon faced is determined by which playable Pokémon the player has available and is permanently replaced when a new character is unlocked. When there is no Pokémon character unlocked, then, the Giant Pokémon will be a Giant Pikachu, as it is the only starter Pokémon character; when Jigglypuff is unlocked, it will replaced Pikachu to become a Giant Jigglypuff; finally, when Mewtwo is unlocked, Jigglypuff gets replaced and the player permanently fight a Giant Mewtwo whenever the stage is replayed.
In Super Smash Flash 2
- Main article: Master Hand (Super Smash Flash 2)
Master Hand serves once again as the final boss of Classic mode in the reboot Super Smash Flash 2. Two Master Hands also appear as bosses in event #51, ?????. Coming with a new and updated custom design, his battle takes place in the new incarnation of Final Destination and his stamina varies per difficulty as well. Compared to his Super Smash Flash version, he has been given many more attacks.
- Main article: Mother Brain
Mother Brain is a recurring antagonist of the Metroid series and, in addition to appearing as an Assist Trophy in SSF2, is a boss fought in event #40, The Mother Brain. The fight takes place on Tourian, a stage exclusive to this event, where Mother Brain appears on the left side. She has 200 health points of stamina and summons Rinkas, small projectiles that deal weak damage and knockback. Additionally, her eye can rapidly flash colors for a few seconds and then fire the Laser Brain Attack, a large colorful beam that targets the player and deals strong damage and knockback.
On level 3 of Classic mode, a giant opponent is faced with the aid of two allies. As expected, it has a bigger hurtbox that makes it vulnerable to attacks but conversely its attacks deal more damage and knockback.
Metal character/Metal Bros.
- Main article: Metal Bros.
On level 9 of Classic mode, the penultimate level before Master Hand, the player faces a metallic character in Metal Cavern. This makes the opponent extremely resistant to knockback, but also very heavy, making them vulnerable to spikes. Reaching this level on Normal or lower difficulty, the metallic opponent is a randomly selected character from the roster. However, reaching this level on Hard or higher difficulty pitches the player against the Metal Bros.: Metal Mario and Metal Luigi. They are, as the name indicates, metallic versions of Mario and Luigi, respectively, and fight more aggressively than the random metal character, which inherently makes the match harder than the latter as the player has to face two opponents at once.
