Dolores Hayes is Radium's lover and assistant researcher for Dr. Rachel Links. Nicknamed “Dolly” by her lover, Dolores is a research and development assistant in BAHRAM’s Orbital Frame Project. Engaged to be married to Radium, Dolores shares his pro-Martian stance, which makes her and Links a prime target to be taken hostage by a UNSF force that manages to infiltrate the BAHRAM test center in an attempt to seize the Orbital Frame Idolo. Even though Radium arrives to rescue her, she suffers a few gunshot wounds in the crossfire, and later dies in the arms of her fiancé on board Idolo. Enraged and delusional, Radium takes Idolo out on a suicide attack on the remaining UNSF forces.
