Glorzo

The Glorzo were an alien race of parasites that inhabited an asteroid.

Biology
The Glorzo were cyclopic and four tentacled molluscans. They attached themselves onto a host, wrapping around their heads and taking control. Their life cycle was short-lived, around thirty minutes, as they only existed to spread their kind to potential hosts. Their host would eventually develop a single egg which birth from the host, instantly killing them and continuing the cycle. They were very sensitive to the sounds of a harmonics which could cause their hosts bellies to explode.

Culture
Originally a primitive culture that existed only to infect more hosts. After Rick Snaches, Morty Smith and Summer Smith discovered their asteroid, all save the latter were infected by the parasites. Summer seemingly survived being a host as she had a tooth pick in her mouth that punctured and killed any parasite that attempted to take control of her head. The Glorzo that controlled Rick and Morty believed her to be a god and started worshiping her. After learning of the sorry existence of their kind, Summer suggested a new way of life for them. With her help, and Rick's spaceship and technology the Glorzo built a city using survivors from shipwrecks and constructed a peaceful society. They were about to launch their first spacecraft to the stars, however after Summer's brother and grandfather freed themselves, they mistook it for a weapon and violently obliterated the civilization.
