Nintendo legend Shigeru Miyamoto has suggested that the Mario Galaxy Movie backstory will officially become canon for future video game releases. Speaking ahead of the film's belated launch in Japan, Miyamoto addressed whether the movie's revelations regarding Princess Peach would be carried forward into upcoming titles.

The New Lore: Peach and Rosalina’s Connection

The film introduces a significant shift in the established lore, providing answers to long-standing fan theories. The Mario Galaxy Movie backstory reveals that Princess Peach and Rosallyna are actually biological sisters.

According to the movie's plot, several key details have been established:

  • Both sisters were originally born from stardust.
  • The siblings were separated at a young age for Peach's safety.
  • Peach was sent to live in the Mushroom Kingdom, where she was raised by the Toads.
  • Following her upbringing, she eventually ascended to the position of Queen.

While fans have debated these cosmic origins for years, this film marks the first time Nintendo has explicitly defined such a deep history for the character.

Implementing the Mario Galaxy Movie Backstory in Future Games

For decades, Miyamoto has been hesitant to implement strict narratives, fearing that too many "character settings" would limit creativity. In an interview with the Japanese website Nintendo Dream Web, he explained that having fixed histories can become a constraint on development.

"Because we don't know what kind of game we'll make next, having too many character settings can become a constraint," Miyamoto explained (via machine translation). He noted that while he is comfortable being bound by gameplay mechanics, he has avoided creating stories to prevent being "bound" by them in the future.

However, with the Mario Galaxy Movie backstory now finalized for the big screen, Miyamoto's stance is shifting. He expressed a desire to expand on these characters using the new foundation.

"That's why, until we made this movie, we hadn't decided on the characters' origins, but now that we've made the movie, it's become fun to expand on the characters in various ways," Miyamoto stated. "Therefore, we want to adhere as much as possible to the settings created in the movie in future games."

A Legacy of Secret Lore

This transition into deeper lore is a major departure from Nintendo's traditional approach. Earlier this month, Miyamoto admitted he had long held a "vague idea" regarding the true relationship between Peach and Rosalina, even though the original Super Mario Galaxy kept their connection ambiguous.

The history of the franchise is also marked by unexpected storytelling. The plot for the original Super Mario Galaxy was famously developed in secret by veteran director Yoshiaki Koizumi, who wrote the game's narrative during late-night sessions while other developers were away. Now, thanks to the film, that era of ambiguity may finally be coming to an end.
