Teknoman

The Earth is invaded by hordes of monstrous Spidercrabs under the control of the Venomoid warlord, Darkon. His first target is the Space-Ring, a huge orbital space station surrounding the Earth. Suddenly, an armored figure appears -- the Teknoman, Blade -- who attempts to stop the attack, but is confronted by Daggar, one of the mutant Teknomen under Darkon's control. In the ensuing battle, Blade is badly wounded and sent plummeting toward the planet below, where his explosive impact creates a gigantic crater. The Space Knights, Ringo and Star, are sent to investigate and are amazed when the injured Blade emerges from the crater. They take him back to their base and nurse him back to health. They have no clue as to Blade's identity or where he came from, and neither does Blade, who can remember only two things: his name is Blade and he must stop the aliens from conquering Earth.

The "Blue Earth" is damaged and is forced to make an emergency landing on the Space-Ring. Ringo questions Blade about his ability to transform, but Blade claims he still can't remember anything. Ringo suspects Blade is hiding something and is determined to find out what.

In an attempt to place Blade under his command, General Galt orders an armed take-over of the Space Knight Command Center. But his plan is foiled by the intervention of the President of the Terran Planetary Council. Meanwhile, a section of the Space-Ring has become detached from the station and is falling toward Earth.

The Space Knights are sent into action against the aliens. The mission is a success, but Blade's energy is almost totally depleted and he is left drifting helplessly in space. Ringo thinks that he and Star should head for Earth while they still can, but Star insists that they go back and save Blade.

Blade tells Tina he now realizes that if he remains in his Teknoman guise for longer than thirty minutes, the Teknoman side of his being will take over. He will lose his "soul" and become a slave of the Venomoid Warlord Darkon. He makes Tina promise to have Ringo blast him out of the sky before that can happen.

The Space Knights receive a distress call from the Space-Ring, supposedly from survivors of the previous attack. Blade and the Space Knights are sent to rescue them, but it turns out there are no survivors.
