Kid Koopa

Kid Koopa was the comboy-themed alter ego employed by King Koopa in The Super Mario Bros. Super Show! episode "Butch Mario & the Luigi Kid". It was also the first alter ego of King Koopa's to be used on the show. The name was only ever mentioned onscreen one time, by Sheriff Mouser.

History
Prior to the events of "Butch Mario & the Luigi Kid", King Koopa took on the alter ego of Kid Koopa, prior to kidnapping Princess Toadstool and hiding her in a mine in the Wild West.

Kid Koopa demanded for Mouser to capture Mario, Luigi and Toad. Although he didn't capture them, Sheriff Mouser and a group of Snifits did lure the trio into a trap of Kid Koopa's, actually a sheriff's office disguised as an Italian restaurant. Posing as a chef, Kid Koopa locked Mario, Luigi and Toad in the jail cell and left them there.

Thanks to Toad, Mario's group managed to escape from the jail cell, and headed to the mine where Princess Toadstool was being held captive. Kid Koopa and his Koopa Troopas followed them there, where he challenged Mario to a quick-draw duel with handheld Piranha Plants. Mario dodged the fireball, used his Piranha Plant to distract the Koopa Pack, and ventured into the mine, where he and his friends found Princess Toadstool. However, they also accidentally fell down a mine shaft and Kid Koopa mocked them for their clumsiness. Mario and Luigi got out of the shaft by rerouting water from a nearby pipe, which also sent Kid Koopa and his Koopa Troopas flying out of the mine.

Appearance
As Kid Koopa, King Koopa sported a cowboy hat, trousers, cowboy boots, and a holster on his belt, which housed a small fireball-spitting Piranha Plant that he could use in place of a gun. King Koopa reused this same apppearance in two more western-themed episodes, "The Great Gold Coin Rush" and "The Provolone Ranger", under the names of "Claim Jump Koopa" and "Billy the Koopa" respectively.
