Koopa Troop

The Koopa Troop is a collection of forces under the command of King Bowser Koopa that serve as the main antagonists of the Mario series. The main foot soldiers of army appear to be Goombas and Koopa Troopas, though other elite ranks also exist, such as Hammer Bros, Koopatrols, and Magikoopas.

Super Mario Bros.
In Super Mario Bros., the Koopa Troop are stated in the official manual to be a clan of turtle sorcerers known for practicing "black magic". In the game, their army invades the Mushroom Kingdom and turns its inhabits into blocks with their magic. They also kidnap Princess Peach, as she is the only one who can reverse their spells. However, they are foiled by Mario and Luigi, who attacked Bowser's castle in World 8 and saved the princess, saving the land from Bowser's control.

Super Mario Bros. 3
Bowser and his seven children lead the Koopa Troop into battle in another attack on the Mushroom Kingdom. This time, the Koopa Troop transformed the local kings into various animals to prevent them from fighting back. The Koopalings, commanders of the Koopa Troop then brought in an airship fleet to stop Mario and Luigi.

Super Mario World
After their defeat from Super Mario Bros. 3, Koopa Troop established a base, as well as a series of castles across Dinosaur Land. The Koopa Troop also captured the island's Yoshi population, with the exception of one.

Super Mario 64
Bowser's next attack was Princess Peach's Castle. Koopa Troop captured Princess Peach as well as several Toads and sealed them inside the castle walls. Bowser set up a series of locked doors that would prevent Mario/Luigi from challenging him directly. Mario/Luigi and Bowser dueled three times before the Koopa Troop surrendered.

Paper Mario
Koopa Troop attacked Princess Peach's castle once again, this time from below. Bowser's castle lifted into the sky where it couldn't be accessed easily. Prior to the game, Koopa Troop attacked the Star Spirits and imprisoned them in cards that were entrusted into the newly hired commanders of the Koopa Troop.

Paper Mario: The Thousand-Year Door
Koopa Troop played a minor role than the previous game. Bowser leads his forces to Rogueport after hearing from Kammy Koopa that someone kidnapped Princess Peach and Mario is collecting mysterious objects known as the Crystal Stars. During the visit to Twilight Town, Bowser and Kammy Koopa assembled the Koopa Troop to do battle against Lord Crump and his horde of X-Nauts. However, the confrontation ended after Bowser accidentally set off a Superbombomb knocking away both sides. As of Chapter 6, members of the Koopa Troop such as Magikoopas and Hammer Bros. can be found in Rogueport Sewers replacing the weaker Goomba species down there.

Mario & Luigi: Superstar Saga
Bowser this time assembled Koopa Troop to head to the Beanbean Kingdom along with Mario to get back Peach's voice. Bowser's troop doesn't assemble at first and even thinks that Luigi wanted to join the Koopa Troop. Luigi at first tried to get away but Bowser caught him and forced him onto his Koopa Cruiser. At one point, Bowser's body was taken over by Cackletta and the newly formed Bowletta took control of the Koopa Troop. Her reign will eventually end after Mario and Luigi defeat Cackletta for good. In this game, Koopa Troop are referred to as the Koopa Baddies by Bowser.
