- Season 2 (24)
A strange cloud incapacitates most of Alpha. Commanding a skeleton crew, Tony sends Eagle 6 to investigate the cloud. The ship returns well past the point where it should have run out of fuel. It lands, without it's crew, manned only by a huge creature that begins to destroy the base. A voice from the cloud announces that the creature has been sent to take the life support core. Lasers, poison, and electricity have no effect, but somehow they must stop this monster before it reaches the Life Support section, and deprives Alpha of it's most essential component.
