Mickey is one of the slaves that Pixie has working in the disc mines.
Season 1[]
Mickey was best friends with Ed and was in on the plan to escape captivity using an excavated iron bird until the Clays catch him and punish him. They continue to use him as an example when things go wrong, publicly beating him to scare the other slaves.
When the Searchers arrive at the excavation site, Genki steps in to save Mickey, and they drive the Clays away. Mickey encourages the slaves to escape and they make a run for it, but in the process he uses himself as a decoy and gets recaptured. Pixie has him tied to a post and set out in plain sight to bait the Searchers into revealing themselves. After Pixie knocks Genki and Mocchi over a cliff, they climb out of the chasm to find Mickey nearly dead. They nurse him back to health, and he gives them directions to Pixie's Castle.
Season 2[]
Mickey can be seen again at the end of the season, fighting the Baddies by air in a fleet of excavated Iron Birds, alongside his best friend and other former North Town captives.
