Ludwig

Ludwig Von "Butt" Koopa is the oldest Koopaling, and one of the secondary antagonists of The Koopa Kids!. He knows only two words, the words are his name, Ludwig and his commonly said phrase; butt. He has yellow skin, blue hair, one tooth, and Ludwig's gray wand (with a blue crystal on it).

However, since The Koopa Kids! episode isn't canon anymore and is instead remade with The Koopalings! He isn't Bowser Junior's Biological Siblings and is instead a Clone from a Clone Machine.
