Space Ghost Coast to Coast - Season 2 Episode 9
Urges

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.
