Released in France on April 1, 2026, Super Mario Galaxy, the movie leaves many spectators with stars in their eyes… and some questions about its very dense ending. Between Bowser becoming a skeleton, Peach and Harmony revealed as sisters and a massive tease of future films Nintendodifficult to assemble everything hot.
Warning: full spoilers. Here we return to the last act, the Peach/Harmonie arc, the fate of Bowser and the two post-credits scenes, to explain what this conclusion prepares for the next chapter of the Mario universe in cinema.
Super Mario Galaxy the Movie: What Really Happens in the Finale?
The climax takes place on Bowser Jr.’s dump planet, transformed into a gigantic trap like Mario Maker. Mario, Peach, Luigi, Yoshi, Toad and Fox McCloud progress through a level full of traps until Bowser falls into the lava. He then returns to Dry Bowsersuper-powerful skeleton version, that Luigi, Yoshi and a cameo of Mr Game & Watch eventually disintegrate.
At the same time, Peach reaches Harmony’s cell, exhausted by the Boomsday weapon which siphons her energy. By joining their hands, the two princesses unleash the “power of the cosmos” and break the prison. Flashbacks confirm that they are sisters, born from stardust, hunted as children by a never-identified hunter, likely future big bad. Mario, doped with the Red Star, crosses a dragon of paint to extract Bowser Jr. and return him to his father, initiating a reconciliation.
Peach, Harmonie and the Bowsers: what the ending changes for the Mario universe
The film finally canonizes an old fan theory: Peach and Harmony are linked well beyond the games’ simple visual nod Super Mario Galaxy. Here, they literally become guardians of the cosmos, capable of powering a weapon as well as saving galaxies. Peach is no longer just sovereign of the Mushroom Kingdom, she must deal with a cosmic destiny shared with her sister.
On the Mushroom Kingdom side, the castle torn down by Bowser leaves a gaping crater. A final SNES pixel-art montage shows its reconstruction, before Mario plants the flag at the top with a Cape Feather that evokes Super Mario World. The circle is complete: return to a reassuring “level 1-1”, but in a world where Bowser and Bowser Jr. have initiated a form of redemption and where the universe has expanded to include galaxies.
Two post-credits scenes from Super Mario Galaxy: towards a Nintendo Cinematic Universe?
Yes, there are two post-credits scenes. The first, in mid-credits, takes place on an icy planet serving as a prison. Fox McCloudaccompanied by a Toad, announces that he is entering his system after Peach repairs his ship. We then discover Bowser Jr. locked up with Dry Bowser’s head, watched by Lumaleewho became a mocking guard. Given the insistence of actor Glen Powell and the green light from Shigeru Miyamoto reported by the press, this is clearly not a simple cameo but an obvious springboard for a film Star Fox.
The second scene, at the very end, takes place in a hub of the Gateway Galaxy. A thief Ukiki is stopped dead by a gloved hand: the camera reveals the princess Daisymodernized look, silent but ultra confident. Her presence teases both a future romance with Luigi and the opening towards Sarasalandwhich fits with the idea of a third film closer to Super Mario Land. By combining Fox, Daisy and the confirmation of the Peach/Harmonie link, this ending clearly lays the foundations of a true shared universe Nintendobefore a possible crossover type Super Smash Bros..
