Starfire is rescued by a young radioactive soldier named Red Star, who hides away in a battle shelter to prevent his power from harming others. When the rest of the Titans arrive, however, they find out the creature is derived from his power. Red Star joins the Titans in defeating the radioactive creature, but the battle causes a change in him. Red Star asks Starfire to send him into space, where he releases his power. Red Star is now a Titan.
