Super Mario Bros. 3
The Koopalings debuted in Super Mario Bros. 3, where they took over the 7 kingdoms of Mushroom Land, invading it at full force with Bowser's troops. They transformed their rulers into animals (or in later versions, different versions of Mario characters). Each Koopaling was on their airship waiting patiently for Mario to arrive. Unsurprisingly, Mario defeated Bowser's seven minions, and learns that Bowser kidnapped Princess Peach, and the Koopalings were used to distract Mario.
Super Mario World
This time Bowser and his Koopalings invaded Dinosaur Land, the place where Yoshi's species live peacefully. Bowser gave a portion of earth to each Koopaling. The Yoshis were no match for the Koopalings, as they easily sealed them in eggs, and some even turned into babies, and spread them around the land, being most prominent in Star Road. At the same time, Mario, Luigi and Princess Peach wanted to go for vacations to Dinosaur Land, and as they arrived, Mario and Luigi found out about the Super Leaf, a new power-up, and they used it and flew around a portion of Yoshi's Island. but when they returned, they noticed that Peach was kidnapped by Bowser, who by coincidence was in Dinosaur Land aswell. The Mario Bros. then go for a new adventure, where they defeated Bowser's seven commanders, and defeated Bowser himself. The seven Koopalings were defeated for good, as they suffered horrible demise.
Mario & Luigi: Superstar Saga
A long time later, after countless events in the Mushroom and Beanbean Kingdom, Bowletta and Fawful decide to go back to Dark Land and takes Bowser's flying fortress. She started attacking the Beanbean Kingdom, and the Mario Bros. arrived into the fortress, known as Bowser Castle. Bowletta, who was ready to destroy the Mario Bros., called the seven Koopalings. The Mario Bros. though, defeated the Seven Koopalings all over again. Three of them (Roy, Wendy and Larry) has a time bomb. If a certain number of turns passed, the Mario Bros. would die instantly. For unknown reasons, the Koopalings had no dialogue, and acted like regular monsters.
Additionally, the seven original Koopalings were set to appear in Super Princess Peach but were cut from the final game for unknown reasons.
The names of the Koopalings in The Adventures of Super Mario Bros. 3 and Super Mario World, two television shows, were changed. This was because the cartoon was in development before the game was officially released worldwide. The names for them were Cheatsy (Larry), Big Mouth (Morton), Kootie Pie (Wendy), Hop (Iggy), Bully (Roy), Hip (Lemmy), and Kooky (Ludwig). All Koopalings appeared in "Crimes R Us" and "7 Continents for 7 Koopas".
