Mario.exe is obviously based on the art of Super Horror Mario and apparently on Coolrash's Mario.exe due to the poisonous mushrooms in its mechanics. Horror has no backstory, as it was only created to be a piece of art, while the mod, it is made clear, is a demonic entity. Although it is popularly called Mario.exe, its real name seems to be Horror Mario (name given by its creator) since it is always called that way. The original artist of Mario.exe(Shadow-Shana) is OK with their art being used, as long as credit is given. Horror Mario is portrayed in the mod as Mario.exe being a demonic entity residing in a cartridge. Mario.exe is the main antagonist of the Friday Night Funkin' mod, Mario's Madness.
