Under Char Aznable's command, he and his colleagues, Kohm, Crown, and others, challenge the SCV-70 White Base just before it enters the Earth's atmosphere. When they were unable to approach the White Base due to its heavy fire, Char gave them a stern rebuke, telling them to approach and strike. Later, when in combat with the Gundam, J.Q. approached the Gundam when it ran out of bazooka ammunition. When he attacked to strike with the butt of his Zaku machine gun, he was hit by the Gundam's head-mounted Vulcans at close range. J.Q. begged Char for help, but was killed in action when his Zaku exploded.
