The Garbageman had dreams of his own kingdom. He chose to make his home on an island used as a landfill. For subjects, he kidnapped homeless people and forced them to work as his slaves. When he kidnapped The Professor, he attracted the Turtles' attention. Ultimately, they put an end to his plans. He was knocked into Hudson Bay; the Turtles, under the impression that his size limited his ability to swim, dived into the water to rescue the Garbageman. However, when they reached the bottom, his chair was empty.
The Garbageman later appeared in his own underwater city, Donatello and Michelangelo, riding in the Shell Sub, encounter Garbageman's realm of refuse. The two Turtles are captured and held prisoner in Junklantis, where they discover that the shipwrecks to which have birth to the city were caused by The Garbageman himself. Don and Mike escape in the Shell Sub and destroy Junklantis, but are chased by The Garbageman in his own submarine. They defeat The Garbageman and his sub falls into a crevasse in the ocean floor., which was made from wrecked ships.
Garbageman was slated to appear in the Lost Season episode, "Nightmares Recycled". The plot was supposed to resolve around the revelation that The Garbageman and Hun were born as conjoined twins, separated at birth by a seedy, back-alley surgeon; the baby that would later become Garbageman was thrown in the trash, whereas Hun was kept and raised.Peter Laird stated that it would have also been the episode where Garbageman died, by being tossed into a vat of acid. This was deemed by the powers-that-be at 4Kids as inappropriate for children's programming, and thus, the episode was scrapped before being completed.
