In one stage he is seen piloting a mechanical version of Kracko, and in another, he controls Yadogaine: A giant, mechanical beetle in Jam Jungle. Doc doesn't seem to have any physical powers and only attacks with machines. Doc features in the sub-game Treasure Shot. Doc makes a minor appearance in Kirby Mass Attack. He appears in Daroach's Airship after beating Dedede Resort.
