A number of huge discoveries about Nintendo games have leaked as of late, including plans for a scrapped Pokemon MMO (on the Game Boy Advance, no less!) and a prototype of Yoshi’s Island. Today, though, the holy grail of Mario may have been discovered: Luigi was originally planned for Super Mario 64.
Word of a multiplayer mode being planned for the game has been known for years (and Luigi truthers have existed for just as long — “L Is Real 2401” may as well be the Mario 64 equivalent of QAnon), but proof has never existed until today, when a source code leak showed textures and code references to everyone’s (second) favorite plumber.

This is a pretty crazy discovery, as while it’s been speculated forever that Luigi was probably at least up for inclusion in the Mario franchise’s 3D debut, proof has not been found. Thanks to these massive Nintendo source code dumps, however, we can finally see what could have been.
While Luigi did not appear in the release version of Super Mario 64, he made his first appearance in the 3D era in Mario Kart 64.
