Make way for the heir to the throne! Bowser Jr. first made his existence known during Mario’s vacation to Isle Delfino. Since then, he’s been a consistent thorn in the Mushroom Kingdom’s side, helping his dad with whatever plot he has cooked up. He fights entirely from within the Koopa Clown Car, which protects him a bit. If you manage to land a hit on Bowser Jr. himself, however, he’ll take more damage, so aim carefully!
