Colonel Perez is the commanding officer of the invasion group in Panama, fighting for the Gran Colombian Empire. His soldiers assaulted Maza's rebel hideout, and took Danny Green, Pablo, and several resistance fighters as prisoners, and executed a few of them, including Pablo. He was later captured during the invasion plot by Danny Green, Sasha Cooper, and Armando Maza, only to escape. He was going to warn his soldiers about the plot to sabotage the bridge when he ran across to join them, but was mistaken for a resistance fighter and shot. The advancing unit for the Gran Colombian Empire realized they shot Perez, shortly before the Fuel Truck armed with semtex riding behind him blew up, destroying the bridge and engulfing his body in flames.
