At the dedication ceremony for a new courthouse built in honor of our heroes, 13 year-old Earl Sump, bespectacled and dressed in a homemade superhero suit, captures two pick-pockets in the crowd. His reward- a day spent at Monitor with his idols, the Defenders of the Earth. Immediately Earl's overzealous nature endangers our heroes --he almost causes the Defender ship to crash, and when the Defenders fly out to a distant planet to investigate some strange behavior, Earl stows away, his antics on board causing Flash's ship to run aground and nearly be destroyed. Back on Monitor Earl locks Jedda in a storage compartment and hijacks a ship which he pilots to Ice Station Earth. Unintentionally he rewires Octon, turning the evil computer into his amicable sidekick, and brings him back to Monitor. Earl then plans a day of celebration in his honor, inviting all of Central City to take part. This all invokes the wrath of Ming, who invades the party. Earl unintentionally turns Octon back into his old self, and it looks as if Ming will destroy the residents of Central City, however the Defenders arrive in the nick of time to drive Ming away and save the populace.
