The Koopa Kids
Bowser's little kiddies get their respect thread.
The little chillens of King Koopa make their daddy proud...if they can get rid of two certain plumbers, that is.
Bowser/Koopa Jr.
Bowser Jr., known in Japan as Koopa Jr. (not to be confused with Baby Bowser in Super Mario World 2), is the child of Bowser that debuted in Super Mario Sunshine. He acts as the main antagonist of both Super Mario Sunshine (where he first appears as Shadow Mario) and New Super Mario Bros., with his father only playing a minor role in each.
His age is unknown, (though he is thought to presumably be somewhere between 4 and 10 years old), so whether or not his maturity is approptiate for his age is a mystery. He is the youngest of Bowser's children. He also possesses a cunning intelligence his father does not show, and is thought to be smarter than him as well. When ever he loses something, usually a fight or a competition, he either cries or throws a fit (however, he cries less often than he did in earlier games). Much about him remains a mystery, but the biggest of all are the identity of his mother and his relationship with the other seven Koopalings.
The 7 Koopalings
Koopaling is a generic title given to seven children of King Bowser who help him in various games. They first appeared in Super Mario Bros. 3 where the original seven were introduced. Each Koopaling was a boss at the end of one of the game’s seven kingdoms. Tare 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.
