Nintendo References/Cameos Found In The Super Mario Galaxy Movie
Sometimes movies like to borrow characters from other corners of their universe, and The Super Mario Galaxy Movie does exactly that—sprinkling familiar Nintendo faces throughout its galaxy-hopping adventure.
1. R.O.B. (NES)

When Peach and Toad visit the Gateway Galaxy looking for directions, they encounter R.O.B. manning an information booth.
He’s hilariously slow at delivering information, turning what should be a quick exchange into a frustrating waiting game that feels like watching a dial-up connection load in 2026.
But hey, he is STILL maybe our favourite robot!
Fun fact about R.O.B: The whole thing was a clever marketing move to get the NES into toy stores during a time when video game consoles were a tough sell, and honestly, R.O.B. deserves credit for helping save the industry even if he was kind of useless at his actual job.
2. Fox McCloud (Star Fox Series)

Fox McCloud shows up as a pilot hanging around the Gateway Galaxy, complete with his iconic Arwing parked nearby.
Not only that, but you’ll also get to catch quick glimpses of his whole crew during that flashback, that include Falco, Peppy, and Slippy!
More the merrier, we guess?
Fun fact about Fox McCloud: Fox McCloud first appeared in the 1993 Super NES game Star Fox, which was basically Nintendo showing off what their Super FX chip could do with early 3D graphics.
3. Baby Mario and Baby Luigi (Super Mario World 2: Yoshi’s Island)

We’ve said this, but we have to say it again. MAJOR SPOILERS AHEAD.
During a key moment aboard Bowser’s ship, Bowser Jr. whips out what looks suspiciously like a Super Scope and fires it at Mario and Luigi.
This incident transforms them into adorable, diaper-wearing babies, complete with those oversized caps that make them look even more Italian.
Seeing the brothers reduced to their infant selves feels like a loving nod to anyone who spent hours playing Yoshi’s Island back in the day.
Fun fact about Baby Mario and Baby Luigi: The infant brothers made their first appearance in Super Mario World 2: Yoshi’s Island in 1995, where the entire plot revolved around Yoshi carrying Baby Mario on his back to rescue Baby Luigi from Kamek.
4. Lumalee’s Dark Nature (The Super Mario Bros. Movie)

This might not be as impactful for those who have not watched the first Mario movie.
Basically, Lumalee is known for his dark humor. This time round, his sinister-funny nature feels even sharper
The movie gives you a bit more context for why this adorable blue star is so obsessed with oblivion.
The Lumas from Super Mario Galaxy actually sacrifice themselves by transforming into planets and supernovas, which explains why Lumalee treats death like an old friend rather than something to fear.
Fun fact about Lumalee: In the post-credits scene, Lumalee appears one last time to serenade the audience with a saxophone cover of the Super Mario Bros. theme.
5. T-Rex (Super Mario Odyssey)

The T-Rex in question appears during the same scene where Mario and Luigi are transformed into babies.
This particular T-Rex is pulled straight from Super Mario Odyssey, where Mario could actually possess the prehistoric predator using Cappy and stomp around, wreaking havoc.
Fun fact about the T-Rex: In the original game, the T-Rex was found sleeping in the Cascade Kingdom’s Fossil Falls, completely harmless until Mario decided to take it for a spin—though the movie version seems much less interested in napping.
6. Mr. Game & Watch (Smash Series)

During the final battle, you’ll catch Luigi grabbing Bowser Jr.’s Magic Paintbrush and frantically sketching something to help in the fight. It was such an awesome scene and made even better in IMAX!
What emerges is Mr. Game & Watch, that flat, featureless character who looks like he wandered out of a calculator display.
Luigi even apologizes for his terrible drawing skills, which is sweet, because honestly, that’s just what Mr. Game & Watch looks like.
Fun fact about Mr. Game & Watch: The iconic character actually predates Mario by about a year, originating from Nintendo’s handheld Game & Watch devices in the early 1980s, making him technically older than the plumber himself!
7. Princess Daisy (Super Mario Series)

The first incident hinting at Princess Daisy’s involvement in the movie is a sign in the background with Daisy’s signature yellow and teal flower emblem on it. You REALLY have to pay attention to notice it, though.
Her full appearance is then shown during the post-credit scene, where she is seen teaching a snatch thief monkey a lesson!
Fun fact about Princess Daisy: She made her debut in the 1989 Game Boy title Super Mario Land, where she was the damsel in distress instead of Peach—making her one of the franchise’s earliest leading ladies.
Well, this is all we could catch in terms of references and cameo appearances. Did you catch something that we didn’t? Let us know!
