The Super Mario Galaxy Movie (2026): Ending Explained

The film picks up almost exactly where the first one left off, with Mario and Luigi finding the dinosaur-like Yoshi (voiced by Donald Glover), who was teased in the first movie's post-credits scene. Rosalina's Lumas end up working with Team Mario after the Arwing belonging to Fox McCloud (voiced by Glen Powell) is damaged. Bowser Jr. wants to siphon off Rosalina's magic to power a world-ending cannon on his personal Death-Star-like base, Planet Bowser, a junk planet. Bowser, meanwhile, struggles with Luigi's efforts to rehabilitate him, even helping Mario at points and trying to move past his anger issues. After being rescued from an unnamed planet by the Lumas, Mario, Peach, Luigi, Fox, Yoshi, and Toad head to Bowser Jr.'s Junk Planet to rescue Rosalina. A distraction lets Mario, Luigi, Peach, and Yoshi sneak into Bowser Jr.'s fortress. Before they can enter, Peach and Mario spring a trap that resembles a Mario Maker level. Peach slips away from the main fight to reach Rosalina but can't break her out of her cell on her own. Along the way, the film reveals that Peach is Rosalina's long-lost sister.

Once Peach and Rosalina are reunited, their shared power shatters Bowser Jr.'s base and turns his constructed world into one of natural beauty, a payoff for the film's sibling reveal. The world-ending cannon is destroyed along with the base, and the threat is over.

The emotional counterpoint is Bowser. Mario, who has mistrusted him throughout, ends up seeing him with more humanity, and at one point equips a Red Star power-up out of pity for Bowser's longing for a family. Even so, the film ends with Bowser and Bowser Jr. behind bars.

The final beats are celebratory. The whole community rallies to rebuild the castle from the ground up, and Mario grabs a Cape Feather and glides to the top of the new flagpole, planting a Peach flag in a nod to the way players finish a stage in the games. It formally closes the story and sets up a peaceful new era.

One loose thread the film leaves unexplained is the relationship between Peach and Rosalina afterward. A generous reading is that Rosalina had kept her distance to keep Peach safe, but by the end they have no problem being close.
