Giant Isopods are a sapient alien race native to Jupiter's moon Europa. They are ocean-dwelling creatures with pale eyes and antennae, and have been described as looking like a gigantic pill-bug. Some of them have also been living on Earth in the deep ocean, where they sometimes abduct other creatures and bring them in their spaceships to Europa to be devoured by their Isopod brethren. When this plan fails, they usually order pizza instead.
