By: KaeKaitlinLudwig Von was suppose to be, then Roy. I'm pretty sure Bowser Jr. Is the youngest though. I mean, it makes sense- Bowser Jr. Didn't Exist back when the Koopa Kids first came out. And Ludwig does definently seem to be the oldest- but, one that confuses me that can change everything---- Bowser Jr.'s the only one that actually has his horns.
Who's the oldest: Ludwig, Bowser Jr., or NETHER???
