Only a few months remain until The Super Mario Galaxy Movie's theatrical release, and its plot may have accidentally leaked. This Nintendo Illumination feature will have Mario (Chris Pratt and the gang go beyond the Mushroom Kingdom as Bowser Jr. (Benny Safdie) sets out to rescue his father, Bowser (Jack Black). But according to this leaked plot, there could be more to this rescue mission.

The Super Mario Galaxy Movie is based on the Super Mario Galaxy video game series, released in 2007. The film features the return of the first film's original cast members, like Chris Pratt's Mario, Jack Black's Bowser, Anya Taylor-Joy's Princess Peach, and Charlie Day's Luigi, but it also introduces new characters, like Princess Rosalina, played by Brie Larson, and Bowser Jr., voiced by Benny Safdie. Nintendo and Illumination have released a handful of teasers and trailers, showcasing the Mario cinematic universe expanding with new locations and creatures, as well as some returning faces like Yoshi. But according to this latest plot, another iconic Mario character could be making its cinematic debut.

According to Polygon, the London-based cinema chain Everyman released a now-edited description for the Super Mario Galaxy Movie. It teased that Bowser Jr. has an ally in this latest feature, and that their goal is "world domination." This character has never been shown in any of The Super Mario Galaxy Movie's promotional material to date, and its voice actor has yet to be revealed. As of writing, the plot description in question has been wiped, but this is what it said on the website beforehand:

"After defeating Bowser and saving Brooklyn, Mario faces Wario and Bowser Jr.'s evil alliance. Now, alongside his friends and Yoshi, he must stop their plans for world domination."

Wario's appearance has yet to be fully confirmed. However, back in 2023, Black pitched in an interview that he wants Pedro Pascal to voice the popular character and be the villain in the sequel. He said:

“You know, what if there is a more powerful, more evil villain? Then I may need to be turned to help Mario and the rest to defend our universe against some other unseen force of evil. Are you thinking what I’m thinking? Wario! Pedro Pascal is Wario.”

Who is Wario in 'The Super Mario Bros.' Franchise?

Wario is a character in Nintendo's Mario franchise, who made his debut in 1992 in the Game Boy game Super Mario Land 2: 6 Golden Coins. The character is known for his yellow outfit with purple overalls, with a hat with the letter "W" on it, and is seen as either an anti-hero or an antagonist in the franchise. Just like Mario, Charles Martinet voiced the character from 1993 to 2023. Alongside his Mario appearance, Wario has appeared in other games, including the Wario Land titles, the Super Smash Bros franchise, and Yoshi's Island DS, just to name a few. Just like Mario has Luigi, Wario has his own parter in crime with Waluigi, though the appearance of either of them in the new film remains to be seen.
