2x9 - Space Ghost Coast to Coast

Zorak feels the urge to return to his home planet for "Mantis Mating Season", but is reluctant when he finds out he will die if he mates with a female. Michael Sweet persuades Zorak to make the attempt anyway. Zorak later returns, having been saved by a male Mantis in drag who was part of a resistance movement against the Mantis mating ritual.
