Friend or Foe

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.
