This page describes Giga Bowser in general and his appearance in Melee and Ultimate. For his appearance as Bowser's Final Smash, see Giga Bowser (Final Smash).

Giga Bowser (Giga Koopa (ギガクッパ Giga Kūppā)?) is a gargantuan version of Bowser, making his debut as the main antagonist of the Adventure Mode in Super Smash Bros. Melee. He also appears as Bowser's Final Smash in Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS and Wii U, and Super Smash Bros. Ultimate.

In Melee, he appears as a boss. To fight him, Adventure Mode must be cleared on Normal or higher in 18 minutes or less. He will appear after Bowser is defeated. Defeating him without using a continue rewards you with the Giga Bowser trophy. He also appears in Event 51: The Showdown with Mewtwo and Ganondorf by his side. He can be controlled by using an Action Replay for the Gamecube or using a mod hack for Switch.

In Super Smash Bros. Ultimate

World of Light

In World of Light, he appears as a boss under Galeem's service. His respective sub-world is the Molten Fortress, which is based off Bowser's Castle. Defeating him is required to unlock Bowser for play in the mode. He will later be fought again during the Final Battle when you hit his orb in the Boss Rush section. He retains all of his playable counterpart's attacks while he is fought.

Classic Mode

In Classic Mode, Giga Bowser is the boss for Mario and Captain Falcon. When he is in his first phase, he fights like his normal counterpart does, but after he is knocked off screen, he transforms into his Giga form (his true form) and continues the battle. In this form, he fights like he does in Adventure Mode.

As a Final Smash

Main article: Giga Bowser (Final Smash)

In Brawl, 3DS and Wii U, and Ultimate, Bowser turns into this form by using his Final Smash, Giga Bowser. Here, he is noticeably much larger, scarier-looking and more devastatingly powerful. He appears on the stage for about 12 seconds.

Differences between Bowser and Giga Bowser

  • Approximately 1.6 times larger
  • Invincible flame breath that also droops lava (Melee only)
  • More height gained from Whirling Fortress
  • Whirling Fortress grants 26 Invincibility Frames and pseudo Invincibility Frames after the 26, due to the enormous hitbox
  • Cannot be grabbed
  • Inability to be knocked back (Brawl only)

Special Attributes

Trophy Description (Melee)

To unlock this trophy, one must defeat Giga Bowser in Adventure Mode without continuing.


The Giga Bowser Trophy

An even more imposing figure than the original King of the Koopas, Giga Bowser is roughly twice the size of his scaly, fire-breathing, spike-studded, Super Smash Bros. Melee counterpart. Predictable, this monstrous creature's offensive and defensive powers are a grade higher than those of regular Bowser. Good luck defeating this colossus!

2D Giga Bowser

Giga Bowser in the Game and Watch stage in Melee.

  • Giga Bowser is the only boss in any Smash game to have a damage meter as opposed to Hit Points. This means that simply attacking him isn't enough to KO him, he must instead be knocked off the stage.
  • In Melee, if a CPU Giga Bowser captures an opponent with Koopa Klaw, he can bite his opponent, but no damage will be inflicted.
  • There is some irony in the Giga Bowser trophy description in Melee, as it wishes good luck in defeating Giga Bowser, even though defeating him is one of the requirements for unlocking the trophy.
  • In Smash 4, Giga Bowser's dash and forward smash animations have been reverted to their Brawl counterparts, as Bowser received new animations between the two games.
  • Among the subtle differences between Bowser and Giga Bowser is their eyes - Bowser's eyes make him look like he's concentrating, while Giga Bowser's eyes are manic-looking and somewhat bloodshot.
  • Giga Bowser is one of four bosses who can grab and throw players, the others being Master Hand, Crazy Hand, and Tabuu.
  • Giga Bowser's stance on his Melee trophy is similar to Mario's in Brawl.
  • Strangely, if the player views the narrator voice tracks under Melee's sound test in English, Giga Bowser's Japanese name "Giga Koopa" is announced as one of the numbered tracks. Additionally, if the player listens to this track while the language is set to Japanese, the announcer will refer to him as "Giga Bowser".
  • In Melee, when a CPU Giga Bowser lands or does his Giga Bowser Bomb, the player's controller will start to shake.
  • The word "Giga" in Giga Bowser is often parodied with a dinosaur's name "Giga" in Giganotosaurus (a meat-eating dinosaur larger than Tyrannosaurus Rex). Giga Bowser is a parody of "Giganotosaurus".
  • If by chance Giga Bowser gets shrunken by a Poison Mushroom, he would still be slightly larger than a normal-sized Bowser.
  • If Giga Bowser is defeated in All star mode, he can't continue even if he has enough coins but may fall down as a Mario Trophy.
  • Giga Bowser's model will become disfigured if he appears in Flat Zone.
  • There is a glitch where on a custom stage he may get stuck in a wall. This makes Giga Bowser unable to move.
  • Another glitch is where Giga Bowser gets KO'd in a stamina match and can play with 0 health. This glitch is called the Undead Glitch. It works with Wario Man too.
  • If a Barrel Cannon is thrown at Giga Bowser, he will only repeatedly take damage from it until it falls off the stage or disappears since he is too big to be grabbed.
  • In Super Smash Bros. Ultimate, the boss version of Giga Bowser is actually a regular fighter, but his portrait will not appear in-game and the game will crash if he wins a match as there no audio file of the announcer saying "Giga Bowser".
