A mortal man that replaced every part of his body with a mechanical part (wonders of steam technology as he puts it), Scrapperton is a kindly-seeming robo-man. However, he changes when he obtained a strange gear staff called Mr. Cogsmith, whom he can sync his mind with. The end of his debut episode reveals that the staff is actually the Skeleton King's staff, implying that the staff corrupted him, as it's the staff
that told him to build the mecha realm and possibly to collect Shuggazoom. He collects mostly useless junk, but his collecting habits can get in the way of his mind. He lured the Monkeys to his lair by
capturing Sparx, and soon stole all of their hands and hand attachments.
