Dr. Hans Halvorsen
A giant asteroid is heading toward Earth so some astronauts disembark from a nearby space station to blow it up. The mission is successful, and they return to the station unknowingly bringing back a gooey green substance that mutates into one-eyed tentacled monsters that feed off electricity. Soon the station is crawling with them, and people are being zapped left and right!
South Pole Base Personnel
In 1980, a giant planetoid named Gorath is discovered to be on a collision course with Earth. Even though it is smaller than Earth, its mass is huge enough to crush the Earth and destroy it. A mission sent to observe Gorath is destroyed after all the orbiting ships are drawn into the planetoid. A later mission is sent to observe and the crew barely leaves before suffering the same fate. However Astronaut Tatsuo Kanai is left in a catatonic state due to his near death experience. The Earth's scientists then come up with a desperate plan to build giant rockets at the South Pole to move Earth out of Gorath's path before it is too late.
