In episode 1, Captain Green and Crewman Red are sent to investigate the mysterious disappearance of patrol ships in a region of space supposedly secured from the killbot menace. They approach a rogue planetoid, unaware of the massive killbot cell concealed underground. Powerful electromagnets force their rocket to a crash landing, and after exploring the surface of the planet in search of human life signs (and running into some of the indegenous wildlife) they find a survivor, Captian Lester, from one of the missing patrols, and escape with him back to homeworld.

Unfortunately for the rocketmen, the killbots have implanted a homing beacon in Captain Lester (let's not speculate on exactly how THAT was accomplished... rather unpleasant though, I imagine). Tracking the homing becon, the killbots engage massive planet mover engines and set course for the rocketmen homeworld, using their planet as a space ship.

A battle group is sent to the killbot planet to deal with the killbot menace. Expecting a typically easy victory, the rocketmen are however suprised and outnumbered on the battlefield, and the killbot planet moves ever closer to homeworld, unimpeded.

The rocketmen mount a last line defence of homeworld, while Captain Green and Crewman Red are sent on a secret mission to eliminate the killbot leader, Evilbot, who is overseeing the invasion from his command UFO. Luckily, our heroes are successful in defeating Evilbot, and stop the killbot invasion in time to prevent complete annihilation.

In episode 2, as the killbot planet orbiting homeworld is being destroyed, the nefarious Dr. Moncale seizes his opportunity to scrounge some deactivated killbots floating amongst the space debris. Reprogramming the killbots to obey his commands, he goes to a remote mining colony planet to kidnap colonists and convert them into a cyborg army, hoping to take over homeworld for himself.

Dr. Monacle's efforts do not go unnoticed, however, and Captain Green and Crewman Red are sent to the mining colony to investigate the mysterious killbot attacks. They stumble upon Dr. Monacle's secret hideout, but are easily captured by one of the Killbots.

Dr. Monacle leaves our heroes in a very precarious trap: just as they are about to be vapourized by a powerful laser ray, our heroes appear in a time cube machine to free themselves from the trap. Imparting some wise, time traveller, advice on how to defeat Dr. Monacle, the time travelling duo go back in time to deliver Kung FU and Juggling books to themselves in the past.

Using their new found expertise in the martial arts (and juggling), the rocketmen easily defeat dr monacle's cyborg army. Unfortunately, Dr. Monacle escapes at the last moment.
