Bio: Countdown is a NASA astronaut and electronics engineer, as well as a ranking chess master. Countdown occasionally served with the G.I. Joe team onboard the space shuttle Defiant. He took part in the mission that launched a Joe vehicle into orbit, then dropped it into Trucial Abysmia on a rescue mission to save the group of Joes who survived an attack by Cobra in which a SAW Viper killed several others. Countdown, like most former Joes, is currently a reserve member of the team.
