GWAR: Rendezvous with Ragnarok (1997)

Just when you thought it was safe to get abducted by aliens, Slave Pit offers their take on the extraterrestrial phenomenon. Gwar celebrates the end of the world as the comet Ragnarok threatens to destroy the Earth. When Grey Aliens crash the party and artificially inseminate Slymenstra with Orderus' sperm, the resulting hybrid mutant space child attracts the attention of Gwar's ancient enemy, the giant robot Cardinal Syn and his Holy Warriors from Outer Space.
