Cosmo is a former test animal of the Soviet Space Program. He was launched into Earth's orbit as part of an experiment but he drifted off into space during the 1960's, arriving in Knowhere and at some point being mutated, he eventually came to serve as the station's security chief.
Cosmo met a distraught Nova shortly after he witnessed Suspensor turn into a zombie. He tells Nova that he's on Knowhere, a city right inside the severed head of a giant Celestial. Beings from all over the universe come to Knowhere, waiting for the end of the universe. Right now, the city's population had to go into hiding right after the Luminals brought something in a big box. Worldmind then informs Nova that he had deciphered the writing on the wall, which is a countdown to a timer.
Suspensor attacks them and he is forced to kill her in self defense only to have her allies Cynosure, Crater and Discharge blame him for her death. Unable to fight the three aliens, as he retreats he makes a discovery of a talking dog. However, Cosmo gained Nova’s trust and friendship, and the two set out to find the fiend responsible for all the recent deaths on Knowhere.
