Originating from the Milky Way Wishes storyline of Kirby Super Star/Super Star Ultra, Marx originally used Kirby in his plan to become powerful & the ultimate troublemaker, but after a few years, he's dealt away with his evil ways & become more of a local prankster. Doing practical jokes & being a general annoyance for some, but also being a friend to others! Though he can get cranky if he hasn't had his afternoon snack, similar to Kirby, just more aggressive.
