When the Defenders receive an invitation to pit Dynak-X against a chess-playing computer, they little suspect that it is part of Ming’s plot to implant an electronic maggot into Dynak’s circuits in order to turn her against them and ultimately give Ming access to the world’s weapon’s systems. When Mandrake learns of the maggot’s existence, he shrinks Rick, LJ, Jedda and Kisa (Jedda’s panther friend) to microscopic size (using Rick’s new Microniser ray rather than magic) so they can get inside Dynak and track the creature down.
