A small portion of the Koopa Troop, after their defeat at the hands of the Smithy Gang
The Koopa Troop (named as such in Super Mario RPG: Legend of the Seven Stars and Bowser's bio in Fortune Street), also known as the Turtle Tribe (in the Super Mario Bros. instruction booklet as well as Mario's data for Super Smash Bros.), Turtle Empire (also in the Super Mario Bros. instruction booklet), Bowser Baddies (in Mario & Luigi: Superstar Saga), the Koopa clan (in the Paper Mario series and Bowser's description in Mario Super Sluggers) or simply the Koopa is a group led by King Bowser. The Koopa Troop has taken over the Mushroom Kingdom multiple times and has even attempted to take over the Mushroom World, Dinosaur Land, and the Mushroom Universe. According to Kammy Koopa in Paper Mario, the motive for the clan is to have revenge against all who have treated Koopa Troopas poorly, though many their goals are based entirely on Bowser's own interests. Despite the name Koopa in the troop's name, the troop also contains enemies that aren't Koopas.
The force of the Koopa Troop differs from game to game. Koopa Troopas are the most common and Magikoopas, Hammer Bros. and Koopatrols are among their elites.
During Super Mario RPG: Legend of the Seven Stars, Mario eventually joins the Koopa Troop. When Bowser joined Mario's Party at Booster Tower, he makes Mario, Mallow and Geno honorary members.
In Mario & Luigi: Bowser's Inside Story, the Koopa Troop is shown to be split into different divisions (the Goomba corps, the Shy Guy corps, the Koopa unit, the Bob-omb squad and the Magikoopa corps), as evidenced when Fawful shows Bowser his captured soldiers. As Bowser rescues his soldiers, he is able to use them as attacks, for example, using a squadron of Shy Guys to sling Bowser forward to the enemy.
In The Super Mario Bros. Super Show!, the enemies under the command of King Koopa are often referred to by the Koopa Pack and on one occasion, Koopa Troopers and Team Koopa, though in later episodes of The Super Mario Bros. Super Show!, the name Koopa Pack seemed to be used interchangeably between generic minions of King Koopa and a core group consisting of King Koopa, Mouser, Tryclyde, and a Koopa Troopa.
