- Hiroji Kiyotake originally envisioned the favorite food of Wario as being crepes, but current official bios and various games have established his favorite food as being garlic (pictured).
- An in-game time unit in New Super Luigi U is 1 second, while in New Super Mario Bros. U, an in-game time unit lasts only 0.75 seconds.
- Super Smash Bros. Ultimate is the seventh Mario-related game to receive a PEGI 12+ rating in Europe, being preceded by the four prior Super Smash Bros. installments and the Virtual Console releases of Super Mario 64 DS and New Super Mario Bros.
- While Bowser is generally referred to as "Koopa" in Japan, there are occasions where his localized name is alluded to. For example, in the Japanese version of Mario Kart Wii, the Flame Runner is known as the Super Bowser. Because all regional releases of Super Mario Sunshine use the English voice acting, Peach calls Bowser Jr. "Bowser's son," and Bowser himself calls his family the "royal Koopa line," meaning that Koopa is also his surname in Japan. Bowser Koopa is rarely directly given as his full name, but it has occurred in some officially licensed material such as the White Knuckle Scorin' album comic, as well as certain cartoon episodes and comic issues.
