Intelligence Summary
- Discover the reveals in The Super Mario Galaxy Movie about Princess Peach's past and her relationship with Rosalina.
Introduction
The recently released film, The Super Mario Galaxy Movie, has delivered major revelations about Princess Peach's backstory. Shigeru Miyamoto, Nintendo's legendary creator, recently confirmed that this new information will be treated as canon in future Nintendo games.
The reveal about Peach's backstory
In The Super Mario Galaxy Movie, it is revealed that Princess Peach and Rosalina are sisters, both born from stardust. The story says the sisters were separated at a young age, with Peach being sent to the Mushroom Kingdom for her safety. There, the Toads became her protectors and eventually made her their queen.
The connection between Peach and Rosalina has been a subject of speculation since the release of Super Mario Galaxy nearly two decades ago. Confirming that relationship in the film has delighted many fans who have long wondered about their family ties.
Miyamoto's view on canon and character development
In a recent interview, Shigeru Miyamoto said he wants the backstories established in the film to be integrated into other games in the future. He explained that before the film, he had always been hesitant to lock in strict backstories for characters, because he feared it would limit creativity when making new games. Miyamoto said: "Because we don't know what kind of game we'll make next, too many character settings can become an obstacle."
With the film, Miyamoto now has the opportunity to further develop the characters and their stories. He is excited about the possibilities these canonical changes bring and how they can add depth to these beloved characters.
