Spencer was a 23rd century human man who worked as a security guard in the extraterrestrial animal research department at Urey University on Earth in the 2260s.
History[]
In 2266, Clagg checked up on his fellow guard Spencer, who was guarding a newly-arrived bear-like vrell at the university. Spenser had whipped the animal, and Clagg warned him back. But the vrell attacked his abuser, and Clagg called Barbara McCoy's emergency number for assistance. When she arrived, Clagg reported that state security officers had surrounded the escaped animal at Galileo Tower. (TOS comic: "Furlough to Fury")
