In the episode "Never Koop a Koopa" from the animated series "The Adventures of Super Mario Bros. 3", King Koopa wears a red cape towards the end of the episode, giving him a passing resemblance to King K. Rool. However, this is purely coincidental, as King K. Rool debuted four years after this episode aired in 1990, and in early concept art from around this time K. Rool looked much different. Incidentally, the cartoon version of King Koopa shares K. Rool's similar habit of wearing thematic costumes, and Bowser and his Koopa Troop would take up the Kremlings' usual role of stealing Donkey Kong's banana hoard during the Subspace Emissary story mode in Super Smash Bros. Brawl.
