In The Super Mario Bros. Super Show!, King Koopa would often take on various aliases and costumes and try to in act a dastardly plot of some sort, most commonly trying to conquer a kingdom or steal an ancient treasure and/or artifact; aiding Koopa in these plots were his Koopa Pack and also a sidekick of sorts, most commonly Mouser. In several episodes, King Koopa would capture Princess Toadstool and attempt to blackmail her into giving him the Mushroom Kingdom, although some other episodes implied he already had some measure of control over the kingdom.
Super Mario Generations
King Koopa will return as a secondary antagonist, Bowser being the main one. Like in the show, he will be once again voiced by Harvey Atkin.
