For fighter info, see Bowser Jr. (SSBWU/3DS) and Bowser Jr. (SSBU).

The Koopalings (also known as the Koopa Kids) are the seven siblings who serve among the highest officers in Bowser's army. They appeared in many Mario games as end-of-world bosses, but have been featured less in recent years. In more recent games they often work alongside Bowser Jr. They made their first appearance as playable characters in Mario Kart 8.

In Super Smash Bros. Melee

Although the the Koopalings do not have a physical presence in Super Smash Bros. Melee, are mentioned in Bowser’s Trophy description.

Bowser has a long history of kidnapping Princess Peach to lure his nemesis, Mario, into traps. He leads an enormous group of mischievous creatures, not the least of which are his seven children. With outrageous strength, flammable breath, and more spikes than you can shake a Star Rod at, Bowser is a constant threat.”

In Super Smash Bros. Brawl

The Koopalings themselves are not mentioned but Ludwig does appear as a sticker.

Trophy Info



The leader of the Koopalings, with aggressive tendencies to match. He's easily recognized by his tall, blue hair. In New Super Mario Bros. Wii, he makes his appearance in World 1. You might think he's tough, with his blue fireballs and shell spins, but his patterns are actually pretty easy to read.

Morton Jr.


The biggest of the Koopalings. Morton stands out due to the three strands of hair on his head and...oh, the big star on his face. He's more brawn than brains, and in New Super Mario Bros. 2, he appears in World 4, where he'll stay glued to the spot until you attack him. Maybe he just can't be bothered to move!

Wendy O.


Of all the Koopalings, Wendy's the only girl. She's bold, bossy, big headed, and sees Peach and Daisy as her rivals. Despite her tomboyish nature, she's not afraid to show off her feminine side with a pink bow and heels. In New Super Mario Bros. U, she shows off her graceful ice-skating skills with a spin or two.



One of the Koopalings. Iggy wears black-rimmed glasses, has hair that's sort of pineapplish, and is known for being a bit of a prankster. He talks in a cutesy way but laughs like a maniac. Also, he seems to like taming Chain Chomps, and in New Super Mario Bros. 2, he gets a rampaging Chain Chomp to help him take on Mario.



This heavy guy is one of the Koopalings and likes throwing his weight around. His pink sunglasses might not make him seem evil, but the speed he can go from slacker to soldier certainly does. In Super Mario Bros. 3, he causes earthquakes to stop Mario in his tracks, all while attacking with blasts of magic. Nasty stuff!



The smallest and nimblest of the Koopalings, Lemmy is a little rascal with a wacky, childlike look on his face. In New Super Mario Bros. U, he's the boss of World 1 and rides a giant ball while his colorful Mohawk sways in the breeze. Don't underestimate him, though—his ball attacks are trickier than they look!

Ludwig von


The cleverest of the Koopalings, easily recognized by his big tufts of hair. He's got a mature air about him, but he likes to show off and can sound a bit pompous. In New Super Mario Bros. Wii, he's the boss of World 7 and torments Mario by firing homing magic blasts and floating too high in the air to be jumped on.

In Super Smash Bros. Ultimate

As playable characters

The Koopalings again all appear as Bowser Jr.'s alternate costumes.
