Geeker, Becky and Noah go into hiding on Space Station Zebra, but Mister Moloch sends his most insidious operative, Larry the Virus. Larry is an intelligent mutant strain of the common cold who takes control the bodies of those he infects. GeeKeR alone is immune, and soon he finds himself attacked by everyone on the Space Station... including Becky and Noah.

GeeKeR starts emitting a hideous stench and can't stop. His smell draws an attack from Mister Moloch's goons, as well as the ire of Becky and Noah. Feeling rejected by his friends, GeeKeR runs away to the Wildlife Refuge, declaring that ""animals like stinky things."" But in the Refuge, GeeKeR faces a danger even greater than Mister Moloch: hordes of mutant wildlife led by the mighty Toxic Moose.

Geeker gets a pet alien worm. Becky can't stand worms, and convinces GeeKeR to set the worm free in the tunnels under the city. But neither of them realizes that this type of worm grows to fit whatever it is kept in; down in the tunnels it becomes enormous. Moloch harnesses the giant worm and uses it to track down GeeKeR. Soon, both GeeKeR and Noah are captured, and the only way Becky can save them is to overcome her revulsion and team up with the worm.

GeeKeR gets hold of a bunch of old comic books and decides that the best way for him to be accepted by normal people is to become a superhero. Donning a garish costume with huge inflatable muscles, he becomes GeeKMan, Champion of Justice. Unfortunately, "GeeKMan's" rather destructive heroics turn the people of Neo-Denaire against him. Soon, the whole city is out for his blood.

GeeKeR, Becky and Noah travel a hundred years into the future and discover that Mister Moloch has gained control of GeeKeR and used his powers to conquer the galaxy. Our trio find an extremely elderly Noah languishing in a cell, his mind addled by his long imprisonment. ""Old Noah"" gives them a few murky tips on how to foil Moloch's plan, and they return to the present to fight a seemingly doomed battle to change the course of future history and save the galaxy.
