Biography
"The line looks mostly intact, but it is impossible to get out there and make repairs while we're in the air."

- Galaga Guy

This S.H.I.E.L.D. Technician, when caught playing  on the job by Tony Stark, was only briefly deterred from his game because, after Stark left the bridge with Bruce Banner, he resumed playing.

During the Attack on the Helicarrier, he informed Maria Hill that the explosion caused by Hawkeye disabled one of the rotors of the Helicarrier but it was still intact.

He was one of the civilians who died when Thanos snapped his fingers killing half of all living creatures of the universe. He was close to beating his high score when he died.
