Cooper is an analyst for the SACT, first appearing working with Lt. Steel on a trap to catch Ryder. He later appears watching security at Area 51. It isn't until after Steel leaves SACT that he gets a major role, becoming one of Rozum's most trusted soldiers. He is sent to recruit Lucky Girl, who was currently battling Ryder. He later assists Lucky Girl in an attempt to catch Ryder, but her breaking from the plan causes him to abandon it.
He assists Rozum in excavating the ruins of a Forever Knight Castle, and finds the Forever Seer, who tells them of the Esoterica coming. He later fixes Paradox's time machine to send Rozum back, though it was against Cooper's advice. He holds Ryder off, and captures Spark Plug. He assists in the battle of Area 51.
Cooper is gone for the invasion on Area 51, having been sent undercover in the Esoterica. He convinces Ryder that they share the same enemy, and to go after them.
