The Super Mario Galaxy Movie’s final scenes may be laying the groundwork for a significant Nintendo crossover event. The film expands the scope of the animated Nintendo universe, moving beyond the settings of the previous movie – the Mushroom Kingdom and Brooklyn – and venturing into the cosmos.

Fox McCloud's Role and the Multiverse

During their journey, Mario and his friends encounter Fox McCloud, a refugee from another dimension. Introduced while Princess Peach and Toad search for a pilot in the Gateway Galaxy, Fox explains he was sent to the Mario universe through a wormhole and has been working as a pilot to survive.

A Dimension-Hopping Engine

Fox assists Mario and his friends in saving Princess Rosalina, and as a reward, Rosalina equips his Arwing with an interdimensional engine. This allows him to return home, but more importantly, provides a means to traverse different realities. He now possesses the ability to travel across the Nintendo multiverse and encounter various characters.

Fox and his team could potentially become a peacekeeping force, aiding heroes like Samus in future films. This provides a natural way to introduce the concept of alternate realities, allowing future Nintendo adaptations to exist within a shared universe or in separate timelines.

Rosalina's Powers and a Potential 'Nintendo Avengers'

Rosalina’s involvement in enhancing Fox’s Arwing suggests she also possesses the power to travel between dimensions. This could serve as a convenient plot device for opening up new realities within the Nintendo films.

Fox’s adventures could attract the attention of powerful villains like Tabuu, the main antagonist from Super Smash Bros. Brawl’s campaign. This could necessitate Fox recruiting a team of heroes, potentially leading to a large-scale crossover film similar to Avengers: Endgame, uniting characters from the Mario, Donkey Kong, and Pikmin universes, among others.

Despite Nintendo representatives downplaying the possibility of crossover movies, The Super Mario Galaxy Movie establishes the necessary elements to make such an event feasible. It may only be a matter of time before Nintendo’s film adaptations bring all their heroes together for a monumental crossover.
