A fan theory and running headcanon that Nintendo's Luigi is transgender, built out of his many cross-dressing and fem-coded moments across Mario games.

Where did Trans Luigi come from?

It started on January 4, 2019 when a ResetEra thread flagged that Nintendo's New Super Mario Bros. U Deluxe website added 'Sorry Luigi, only Toadette can use this item!' to the Super Crown description.

What does Trans Luigi mean?

Fans read Nintendo's 'Sorry Luigi!' line, plus older moments like Luigi dressing as Peach in Superstar Saga, as a cheeky nod that Luigi had wanted to transition.

How do you use Trans Luigi?

People typically post Nintendo screenshots of Luigi in fem contexts, often paired with trans pride flag edits of the character, as affectionate queer headcanon rather than an argument.

Is Trans Luigi still popular?

The 2019 Super Crown moment is where it took off, and the theory still circulates in queer gaming communities as a go-to Luigi headcanon, though some fans argued the canon examples only prove cross-dressing.

Trans Luigi is a fan theory that Nintendo's Luigi is transgender, kicked off in January 2019 after an official New Super Mario Bros. U Deluxe item description added a cheeky 'Sorry Luigi!' note about the gender-swapping Super Crown. Fans on ResetEra and Twitter treated it as low-key canon and started compiling decades of Luigi cross-dressing moments as evidence, turning a one-line joke into a running headcanon that still circulates in queer gaming spaces.

Overview

Trans Luigi reads Luigi's long and oddly specific history of fem-coded moments as evidence that Nintendo's second-string plumber had quietly wanted to transition all along. The joke works on two levels at once, as earnest queer headcanon and as a shitpost at Nintendo's expense for writing a line that fans could flip into an outing1. Posters stacked up canon receipts: Luigi dressed as Peach to trick Bowletta in Mario & Luigi: Superstar Saga, Luigi as the Queen piece in Mario Chess, and a comic panel where he admits he likes wearing Peach's clothes2.

The format is usually a text post or thread pointing at one of those Nintendo screenshots, often paired with trans pride flag fan art of Luigi. User @kob_critic's drawing of Luigi against a trans lesbian pride flag was one of the first images attached to the theory5. The tone is affectionate and tongue-in-cheek rather than argumentative, which is part of why it stuck around in queer gaming circles well after the original Super Crown discourse faded.

The spark was a single line of Nintendo copy. On January 4, 2019, ResetEra member JB2448 opened a thread titled 'It's canon that only Toadette can use the Super Crown,' posting a screenshot from the official New Super Mario Bros. U Deluxe site where the Super Crown item description ended with 'Sorry Luigi, only Toadette can use this item!'5. The Super Crown had already been the trigger for the Bowsette craze months earlier, so fans read Nintendo's aside as a direct nod to Luigi having tried the gender-swapping power-up off-camera.

Nintendo made the game and wrote the line; the Trans Luigi meme itself grew out of the fan response to that line, not from any single creator. Earliest viral posts came from Twitter users like @joffeorama within hours of the ResetEra thread1.

How It Spread

The joke moved from ResetEra to Twitter the same day. @joffeorama posted a run of tweets arguing Nintendo had 'low-key' dropped that 'Luigi wants to transition,' which got the framing in front of a much larger audience1. @kob_critic followed with fan art of Luigi in front of a trans lesbian pride flag, giving the theory its first widely shared image5.

Over the next few days the receipts thread took over. User @TheTasteOfALiar compiled Luigi's gender-fluid Nintendo moments into a single viral post, listing the Superstar Saga Peach disguise, the Mario Chess Queen piece, and the comic still of Luigi praising Peach's wardrobe2. Daily Dot's writeup tied the theory to the older Mama Luigi bit from the DIC Super Mario World cartoon, lengthening the canon list even further5.

Not every Luigi fan was sold. Accounts including @Sc0lipede and @MegaLegoLuigiEX pushed back that cross-dressing in a Mario game is not the same thing as being trans, and the back-and-forth became part of the meme's shape3 4. The theory still circulates in trans gaming spaces as a go-to headcanon whenever Luigi comes up.
