Cosmo The Spacedog

Cosmo was formerly a test animal for the Soviet Space Program (СССР). He was launched into Earth's orbit as part of an experiment, but his spacecraft drifted out of orbit during the 1960's, eventually sending him to Knowhere. At some point during spacial drift, cosmic rays mutated him, giving him his psionic powers. Thereafter, he became the station's Chief of Security for Knowhere.
