Once they are defeated, the Spirits are freed, and they return to their original worlds. In the final battle, the fighters contend against all six bosses once more, before battling Galeem and Dharkon simultaneously, while they also fight each other. After this, the Hands will help, and if the armies are still balanced, the player will temporarily control Master Hand to battle an army of puppet fighters. If the fighters maintain balance between the armies, they will battle Master Hand and Palutena (sent by Galeem) as well as Crazy Hand and Bayonetta (sent by Dharkon). If the fighters defeat too many of Galeem's Spirits and not enough of Dharkon's, or if they only fight Galeem, Dharkon will swallow the world with darkness. If the fighters defeat too many of Dharkon's Spirits and not enough of Galeem's, or if they only fight Dharkon, Galeem will consume the world with light. From here, the fighters must battle both the forces of Galeem and the forces of Dharkon. However, Galeem reappears with an army of Spirits. They then battle and defeat Dharkon, sending him into retreat. The fighters defeat Ganon, Marx, and Dracula, the three bosses of Dharkon.

Their victory is short-lived, however, as Dharkon and his army of Crazy Hands arrive, taking control of the remaining Spirits and fighters. They defeat a Master Hand before battling and defeating Galeem. The fighters defeat Giga Bowser, Galleom, and Rathalos, the three bosses powering Galeem's shield. Kirby appears in the large world, where he starts to battle Spirits to help him while also rescuing other fighters. The captured fighters are used to make puppet clones.

The beams are then shown hitting various non-playable characters, turning them into Spirits. Kirby uses the Warp Star's power to temporarily enter another plane of existance to avoid the beams. Galeem's rays of light consume almost all the fighters one by one except for Kirby, who flies on his Warp Star. After some dialogue between fighters, Galeem absorbs all the Master Hands and sends out massive beams of light, which Shulk forsees but is unable to stop in time. The fighters are shown facing Galeem, a large celestial being with an army of Master Hands. The mode starts with every character in the base game standing on a cliff similar to the one in Super Smash Bros. Zelda, Marth, and Pit preparing to battle Galeem.
