Subspace (Part I)
Subspace (Part I) (亜空間, Subspace) is the 29th stage that appears in the Subspace Emissary. The player initially takes control of King Dedede, Ness, or Luigi. As the player travels through the Subspace, they will collect trophies of many of the other characters that were made into trophies by Tabuu.
As Ganondorf hails Master Hand, he realizes that Tabuu is controlling Master Hand with the mysterious Chains of Light, stabbed into all five knuckles and in the middle of the back of the hand, and rushes at him using Dark Dive, but Tabuu smashes him back effortlessly. As Ganondorf falls, he breaks the Chains of Light and frees Master Hand, who rushes at Tabuu. Unfortunately, sheer rage was not enough and Tabuu smashed Master Hand effortlessly.
Meanwhile, the heroes (except Wolf, Sonic, Jigglypuff, Toon Link, King Dedede, Ness, and Luigi) infiltrate the Subspace area, anxiously waiting to storm into it. They rush into a scene in which Tabuu uses his Off Waves to turn the heroes into trophies. As the camera scrolls around, everyone is in trophy form.
Back at King Dedede's castle, Luigi, Ness, and King Dedede are stuck in trophy form. King Dedede's brooches, however, revive Luigi and Ness. After being released from trophy form, they decide to save Dedede and the three heroes set off to find the rest of the gang. After the heroes have rescued Mario, Pit, Marth, Ike, Lucas, the Pokémon Trainer, Captain Falcon, Donkey Kong, Diddy Kong, Olimar, Samus, Pikachu, Fox, Falco & Mr. Game & Watch, they are just about to enter the Great Maze until King Dedede notices Bowser's trophy. He revives him, and then the two kings fight as the other two heroes in the back anxiously watch. After Bowser's been defeated and turned back into trophy form, King Dedede walks up to the trophy again and revives him once again. Only this time, King Dedede smacks Bowser in the nose, which angers him. But Dedede points to the defeated Master Hand, which upsets Bowser when he notices, as Bowser was the only one truly loyal to Master Hand, then Bowser finally realizes what's really going on, and then King Dedede recruits him to his team to enter the Great Maze and find Tabuu.
All the characters that Luigi, Ness and King Dedede recovered in the level return to the team. Bowser also joins the team after the battle with King Dedede, as he realizes Tabuu is the true enemy.
