"So he left that job for the Koopalings. They are a group of high-ranking leaders in the Koopa Troop- and they all happen to be siblings. So teamwork comes easily to them."
- Paper Mario: Wonder World
The Koopalings were mistaken to be Bowser's kids but in a 2012 interview withgame Imformer and Shigeru Myamoto, Shigiru said "Our current story is that the koopalings are not Bowser's kids. Bowser Jr is Bowser's only biological son and we don't know who the mother is." It turns out that the koopalings were adopted by Bowser when they were really young and their real biological father is Bowser's cousin Fredrick Von Koopa and their mother was Gwendolyn Koopa. Their parent's died before their eggs hatched in the Small Koopia and Dark Land Vs the Constitutional Empire of United Creatures War. They think that Bowser is their biological father since he never told them who their real parents were. They were born in this order: Ludwig, Roy, Lemmy, Iggy, Wendy, Morton, and Larry.
They help their Step Dad in his plots, like helping their dad in releasing Paragoombas to eat all the food in the Mushroom Kingdom, messing with the seven continents , making the Mushroom Kingdom float , and [[http://www.mariowiki.com/Toddler_Terrors_of_Time_Travel%7Ctrying to clog up the warp pipe that Mario and Luigi used to get to the Mushroom Kingdom.
There were originally only seven Koopalings (eight if Bowser Jr. is counted), but eventually Bowser ended up adopting more. The following is a list of them from oldest to youngest:
The oldest of the fano Koopalings. Den ran away from his father to the Ocean Lands after he lost a battle. He seems to have a dislike for his adopted dad Bowser.
Ludwig is the oldest and most skilled of the Koopalings. He is an inventor and used to be the leader.
The second oldest of the fanon Koopalings. Troopa wears a spiked shell and a mask, and has a special wand that shoots Koopa shells. He is more quiet than the others, mostly not talking to any of them except Ludwig and Bowser Jr.
A red shelled Koopalings with a decent amount of hair. He is shown to have a huge love of food.
The second oldest of the canon Koopalings. Roy is shown to be a bit of a bully towards his siblings, and being the meaner and tougher one of the group. He usually wears shades.
Despite his wacky attitude and size, Lemmy is actually the third oldest of the canon Koopalings. He is never seen anywhere without his ball, and has a special wand made to shoot out balls. He is said to want to join the circus.
A Koopaling from another dimension. Aiva is immature yet smart.
The middle of the canon Koopalings. Iggy is the most psychotic of the group, shown to scream and yell a lot. He is Lemmys twin brother, but only because they used to look alike. He owns a pet Chain Chomp.
The third youngest of the canon Koopalings and the only canon female. Wendy is seen to have a love for ice skating and rings, as two of her boss battles have included this.
One of younger Koopalings, Abel is one of the 7 Deadly elementals. He is very powerful and can jump really high.
Despite his large size, Morton is the second youngest of the canon Koopalings. E is shown to have a big mouth in the DIC cartoons, and has the ability to ground pound.
Almost the youngest Koopalping. Marco has a good relationship with Iggy, and always wears his backpack over his shell. He has a pet Renzor named Bam Bam.
The youngest of the canon Koopalings. Larry doesn't seem to have any special abilities besides his wand, she'll, and jumping abilities; however, he has recently been classified as the leader of the Koopalings.
The Koopalings appear in Paper Mario: Wonder World as boss characters.
The canon Koopalings have been confirmed to appear in Super Mario Moose, along with their new sibling Troopa. At the moment it is unknown which Koopaling will be the boss of each world.
The original Koopalings will appear in Bowser's Story in the Koopaling Adventure DLC pack. All 7 of them will be playable heros.
