Cerbs was an alien with a rocky, golem-like appearance. He was a soldier in the Earth Alliance.
By 3009, during the Cyberon War, Cerbs was the security chief on the Alliance vessel called the Oblivion Spark, which made him the third-highest-ranking officer on the ship. He was fiercely loyal to Captain Ross and followed him on his exploration of a transport vessel in the Jathar Expanse. Like the others, he was nearly converted into a Cyberon himself after the scouting party were ambushed, but managed to fight off the process after Ross overpowered the will of the Cyberon Commander.
