Koopaling (Ko Kuppa) is the generic title given to the seven children of King Bowser who help him in various games. They first appeared in Super Mario Bros. 3. Each Koopaling was a boss at the end of one of the game’s seven kingdoms. The Koopalings are also world bosses in Super Mario World, Mario is Missing!, Yoshi's Safari, and Hotel Mario. In Mario & Luigi: Superstar Saga, however, they are mini-bosses in Bowser's Castle. They are made up of Larry Koopa, Morton Koopa Jr., Wendy O. Koopa, Iggy Koopa, Roy Koopa, Lemmy Koopa , and Ludwig von Koopa, from youngest to oldest. Most of the Koopalings have wild punk hairstyles and are named after musicians. It is said that each Koopaling was personally designed by a different member of the production staff of Super Mario Bros. 3, which Shigeru Miyamoto explains is a way to honor the creators of the games personally. An eighth Koopaling, named Bowser Jr., is introduced in Super Mario Sunshine, but he has yet to be shown with his siblings.
In The Adventures of Super Mario Bros. 3 by DiC Animation, the original seven Koopalings are given different names based on their given personalities. They are called Cheatsy Koopa, Big Mouth Koopa, Kootie Pie Koopa, Hop Koopa, Bully Koopa, Hip Koopa, and Kooky von Koopa. Aside from their names and personalities, they look slightly different and serve Bowser differently, compared to their video game counterparts. Instead of acting as minions, they act directly as his children, and do things such as seek his attention, and even plot against him. They also appear in the Mario anime, Nintendo Adventure Books, and comic books.
While Bowser Jr. is also a child of Bowser, he is not considered a Koopaling, as he is never seen with his siblings.
