Bosses are characters in the Super Smash Bros. series that appear when certain conditions are met. These conditions range from simply clearing stages with a certain difficulty and time, to playing certain Event Modes.
There are multiple battles in the Smash Bros. series that could be considered boss battles; however, actual bosses are usually unplayable by normal means, and most are much larger than the playable characters.
All of the bosses are beaten by depleting their stamina (with the exception of Giga Bowser). When a boss is beaten, they will usually disappear into the background or fall down on the ground.
In the first two installments of the series, boss characters were usable in normal play through hacks or the Debug menu. Starting from Brawl, the character IDs for the bosses have been removed, meaning they are unplayable in matches even with hacks, although certain other hacks allow the moves they perform to be controlled.

- Main article: Master Hand
The first “true” boss of the Super Smash Bros. series, Master Hand is the master of ceremonies for the series. He is meant to represent the hand of a child playing with his toys and staging story-less fights between his favorite Nintendo characters (the playable characters in the game are, according to the intro movie, no more than dolls made to look like Nintendo characters). He can also represent a god because of how he brought the fighters to life and made the stages. He first appeared in the introduction to the first Super Smash Bros., bringing the characters shown in the intro to life. He then appeared at the end of the 1P Game as the final boss. Going against usual Smash tradition, Master Hand has a certain amount of health that must be whittled down to 0%, as opposed to a percent that must be racked up, leading to a ring-out KO; this is due to Master Hand’s massive size, his ability to fly, and being unaffected by the knockback of attacks. Upon being defeated, Master Hand lets out a deep roar that resembles laughter, and flies off, writhing and exploding, into the distance.
Master Hand has appeared in every Smash Bros. game, reprising his role as the final boss in Classic Mode. Master Hand is fought on Final Destination, which is very similar to his original stage, Master Hand's Residence. He fights essentially the same way as he did in the original game, but with a few new attacks. Upon being defeated, he leaves the stage in the same way that he did in the original game. He can also be fought in Event Match #50, where you face off against him and Crazy Hand at the same time.
Master Hand also appears in the Game Boy Advance game, Kirby and the Amazing Mirror, in which he appears as a miniboss in multiple areas. Upon being defeated, Kirby can inhale him, like other minibosses, and gains the Smash ability, which is based on Kirby’s moveset in Melee. Master Hand, alongside Crazy Hand, also appears as the boss of the Candy Constellation. This is Crazy Hand’s only appearance in the game. The two, like in Melee, have attacks that they use in conjunction with each other. In this battle, neither can be inhaled; they both explode upon defeat.
He appears in Brawl's Boss Battles Mode as one of the game's ten bosses. In Super Smash Bros. for Nintendo 3DS/Wii U, when his health gets depleted by half on 5.6 or higher intensity, he will transform into Master Core. In Super Smash Bros. Ultimate, he makes his first official playable appearance in Adventure Mode: World of Light.
The strange, twisted brother of Master Hand, Crazy Hand is meant to represent the feeling of destroying one’s own creations, as opposed to Master Hand, who is meant to represent the opposite. He was introduced in Super Smash Bros. Melee as a secret boss who fights alongside Master Hand under specific conditions, namely that Classic Mode is cleared on Normal difficulty (or higher) in fewer than 18 minutes. (Crazy Hand will join Master Hand when Master Hand has half of his health left.) Crazy Hand also appears in Event 50: Final Destination Match, where he and Master Hand are fought on Final Destination with 300 health each.
When compared to Master Hand, Crazy Hand can be considered to be much more erratic (i.e. crazy). His idle pose is a strange, erratic movement, and he has multiple strange attacks that are unique to him. Many of his attacks also have side-effects, such as freezing and flowering. When Master Hand and Crazy Hand are fought together, they have several moves that they use in conjunction with each other, such as a high-powered clapping attack.
Crazy Hand has reappeared in every Smash Bros. game since, with new standards on how to fight him in Classic Mode. In Brawl, the player must reach the final level with a difficulty of Hard or higher in at 9 minutes or fewer. Master Hand and Crazy Hand will appear simultaneously at the beginning of the battle.
- Main article: Giga Bowser
Giga Bowser (known as Giga Koopa in Japan) is the secret final boss of Adventure Mode in Melee. As his name suggests, he is a large, powered-up version of Bowser. With a manic expression, a darker, more malevolent color scheme, and a hulking size, Giga Bowser is surely a boss to be remembered.
Upon clearing Adventure Mode in fewer than 18 minutes on Normal difficulty (or higher), Bowser’s trophy, previously thrown into a mysterious abyss below Final Destination, rises back up onto the stage, and is struck by a strange lightning, transforming it into Giga Bowser. During the battle with Giga Bowser, a distorted version of the Final Destination theme that cannot be found in the Sound Test plays. Many of Giga Bowser’s attacks are powered up versions of Bowser’s. His Down Smash attack has an icy effect, while his Forward smash has explosive properties and his Forward tilt has shadow-like effects. Unlike Bowser's, Giga Bowser's Fire Breath attack never diminishes.
In Super Smash Bros. Brawl and onward, Giga Bowser also makes a semi-playable appearance as Bowser's Final Smash, Giga Bowser. When used, Bowser temporarily transforms into Giga Bowser, who is essentially unchanged from Melee, keeping the elemental abilities of his attacks, as well as his massive size. Also, Giga Bowser does not flinch in Brawl. His Down Special, Giga Bowser Bomb, had a wind effect in Melee; this has been lost in Brawl.
In Super Smash Bros. Ultimate, he is still Bowser's Final Smash. However, it has been completely revamped into Stage Wide type where he delivers a powerful punch, KOing any opponents who have high enough damage. He also appears as a boss in Classic Mode for Mario and Captain Falcon, and one of the bosses in Adventure Mode: World of Light, serving as a member of Galeem's army.
- Main article: Petey Piranha
Petey Piranha (known as Boss Pakkun in Japan) is the first revealed boss character in Brawl, and the first “true” boss to come from another series of games, as opposed to being unique to Smash. He appears as a boss in The Subspace Emissary, holding cages that contain Princess Zelda and Princess Peach. He uses both these cages, as well as his own abilities, to attack Kirby. The cage that Kirby attacks will break when Petey is defeated and explodes and the princess contained therein will be freed; The other princess is turned into a trophy, and subsequently taken, by Wario. Petey Piranha has been in Mario Kart Double Dash and Super Mario Sunshine.
- Main article: Rayquaza
Rayquaza (known as Rekkuza in Japan) is the first Pokémon creature to be a boss in adventure mode of Super Smash Bros. Brawl. In the Subspace Emissary, it first appears in the jungle after Diddy Kong goes to investigate a crashed Arwing. It comes out of the water and destroys the Arwing with an energy ball and then kidnaps Diddy. As it goes back in the water, Fox McCloud comes out and attacks the aggressive beast, causing it to lose its grip on Diddy Kong. The Pokémon attacks Fox with energy, but Fox reflects the attack back at the monstrous dragon, sending it tumbling back into the water. After this, Diddy Kong and Fox fight it. Its attacks are loosely based off the Pokémon games, and it has an exceedingly large amount of health.
Rayquaza reappears as a stage hazard on the Kalos Pokémon League stage.
- Main article: Porky Minch
As one of the bosses of the Subspace Emissary and a high-ranked member of the Subspace Army, a general if you will, Porky Minch sends Primids to divert Lucas and sends in his giant statue, The Pig King Statue, which soon hunts Lucas down. This statue is indestructible, so Lucas has no choice but to run; the giant statue destroys giant containers, barrels, enemies and even metallic buildings. Lucas finally comes to a giant marsh which seems to save him—the statue sinks, but it soon respawns.
Lucas then stumbles, and just as the giant statue is about to crush him, someone uses a PK Thunder which causes the statue to tip over, and Ness appears. The statue once again recovers and flies into the air, this time to crush Ness. However, he uses a PK Flash and the statue explodes, revealing Porky Minch himself inside (in his bed-mecha from Mother 3). A battle then ensues. He attacks by running around and by using a variety of lasers, but he is eventually taken down. Porky is brought back by Tabuu to distract the heroes in The Great Maze.
- Main article: Galleom
Galleom is a large transforming robot found in the desert by Marth, Ike, and Meta Knight. Galleom's initial form is a large armored tank equipped with ramming spikes and missiles. But when confronted by the three swordsman, it transformed into an immense purple robot. In this form, he attacks with his large fists, missiles, and tries to crush the protagonists with his sheer bulk. The mechanoid is finally defeated, but not destroyed. He leaps off a cliff and falls through the ground into a tunnel system. There, he confronts Lucas and the Pokémon Trainer, although much weaker this time. After he is defeated a second time, he grabs the two companions and blasts into the sky, revealing a Subspace Bomb concealed in his head. Lucas uses PK Thunder to separate Galleom's arm from his body, releasing the two boys. Galleom is finally destroyed by the detonation of the Subspace Bomb. He is later brought back by Tabuu to confront the heroes yet again in The Great Maze.
In Super Smash Bros. Ultimate, Galleom reappears as a boss in Classic Mode for Dark Pit, Snake, R.O.B., Wolf, King K. Rool, and Min Min, and as one of the bosses in Adventure Mode: World of Light, serving as a member of Galeem's army.
Ridley is the boss of the Subspace Emissary in Brawl who fights Samus and Pikachu after scratching Samus's power suit against the wall. Pikachu frees Samus with a Thunder. The pair then fights Ridley, eventually defeating him.
Ridley reappears in his cybernetic form known as Meta Ridley and chases R.O.B., Olimar, Pikachu, Samus, Captain Falcon, Donkey Kong, and Diddy Kong in the Falcon Flyer. They battle him atop of the Flyer, defeating him and sending his body crashing back into the factory's vents, just as the whole island is destroyed.
Both Ridley forms are reincarnated by Tabuu as enemies in his Great Maze.
- Main article: Duon
Duon is an immense, double-sided robot fought on the Battleship Halberd. Duon is created when Snake, Lucario, and Meta Knight destroy the Mr. Game and Watch clones that are maintaining the bridge. As aforementioned, Duon has two different sides: one is a bright blue and specializes at melee attacks and the other is pink and possesses long-range attacks. The blue side has two drill-like appendages and a large blade on its head. It can also fire explosive mines from its shoulders. The pink side can fire several energy blasts from its arm cannons in quick succession. It also fires three blue energy blasts from its head cannon and launches missiles from its shoulders. The beast can also leap into the air to try to crush the heroes and can spin around to cause damage. Upon its defeat, Duon melts into a puddle of shadow bugs and reveals the trophy of Mr. Game and Watch. Duon will attempt to stop the heroes again in The Great Maze.
