If there's one kind of recolor that frequently pops up around Fantendo, it's
another fan-made koopaling the one that appears to be the long-lost brother of Mario and Luigi. They are often shameless Mario recolors, and are the Fantendo version of the "Sonic's long-lost brother", the most infamous kind of recolor OC. Despite this, fan-made Koopalings are even more frequent.
Every Mario recolor will be added here, whether they are actually related to Mario or not.
