Premiere Episode. After stealing GeeKeR from Dr. Maston, GeeKeR's self-destruct mode initiates, a feature Dr. Maston put in to keep GeeKeR from falling into the wrong hands. Becky and Noah have no choice but to seek Maston's help in this matter. Can Becky and Noah defuse GeeKeR before he makes like a bomb and goes BOOM!?

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.

When Geeker morphs into a dinosaur and finds himself unable to change back, Noah must hide him in Dinopolis, the hidden city of the Dinosaurs where no human is allowed. But this brings the wrath of Mister Moloch down on Dinos everywhere, and soon Noah must choose between protecting his friend and saving his people.

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.

Doctor Maston finally succeeds in creating another artificial human, GKR 23. GKR 23, equipped with a computer brain, is even more powerful than GeeKeR. 23 soon breaks free of Mister Moloch's control and sets out to destroy all humanity so that he can repopulate the earth with superior, artificial beings like himself. Now it is up to Geeker to defeat the virtually indestructible 23.

GeeKeR experiences love at last, falling hard for Sirena, a bizarre, tentacled alien woman. Becky is suspicious; it seems as if this alien has some strange power over men. But even when it becomes obvious that Sirena is working for Mister Moloch, GeeKeR refuses to abandon his ""true love"" and walks willingly into Moloch's clutches. Can GeeKeR break the chains of love and do the right thing?

A strange monster is wreaking havoc on the city of Neo-Denaire. Becky and Noah are shocked to discover the the ""monster"" is actually a sleep-walking GeeKeR. Noah learns the cause of GeeKeR's Jekyll-and-Hyde transformations; a signal beamed at GeeKeR from an orbiting satellite. But GeeKeR is forced to stay awake to avoid becoming a monster, and his sleep deprivation-induced hallucinations cause no end of trouble for our trio.

Mister Moloch sets hundreds of ravenous, mechanical Cyberplants loose on Neo-Denaire, programming them to capture GeeKeR and his friends. When Becky and Noah are captured, the fuzz-brained GeeKeR must prove that he can be independent and track them down all by himself. GeeKeR's attempts at sleuthing are ridiculous in the extreme, and matters are complicated when the Cyberplants get out of control and start wrecking the whole city.

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.

Doctor Maston implants a tracer in Noah so that Mister Moloch can track him and capture GeeKeR. But the tracer affects Noah's brain, causing him to gradually revert to savagery. Noah soon goes off on a berserk rampage, and Becky and GeeKeR have to track him down. But when they find him, they discover that the nine-foot dino would just as soon chow down on friends as strangers.

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.
