Bowser Jr. is the youngest son of Bowser that first appeared in Super Mario Sunshine and is the most mischief causing of the Koopalings(even though he is not really considered a Koopaling). He wears a bandana around his neck which lets him transform into Shadow Mario. He helps to capture the princess and gives Mario and Luigi trouble. He is an antagonist alongside Bowser.
Since Bowser Jr. takes after his dad, he can also command the Koopa Troop. He also rides a mini version of his dad's Koopa Car and battles Mario in it. In Super Mario Sunshine, he believes that Princess Peach is his mother and that Mario is a ruthless villain that takes her away. Since Bowser told him that wasn't true at the end of the game, it's unknown who really is his mother.
Bowser Jr. also appears as a earnable sticker available in Super Smash Bros. Brawl.
Bowser Jr. appears in Super Smash Bros Wii U as a playable character. He can be customized to be the Koopalings.
