but to those who want a quick answer: in Super Mario Bros: The Lost Levels (aka the Japanese version of Mario Bros 2) there is a thing called brother byte" to determine the current brother the player is playing as. There are two valid brothers: Mario (0) and Luigi (1), and 254 invalid ones. Out of them, only three have the closest thing to names that are not glitched: Iolui (Brother 4), Uigiy (Brother 72) and Ariol (Brother 140).

I thought it would be cool to make models out of them cuz why the heck not? :3
