Michelle LaChance had a knack for computers, and liked the rush of being able to hack into any computer systems. She stayed undetected for some time, until she hacked her way into U.S. Army computers and discovered the Army's experimental nano-mite program. She was arrested by the Feds, but they realized they could make use of her skills and she began working for the government. Firewall was put on temporary assignment with the G.I. Joe team to help put a stop to Cobra's nano-mites.

Firewall continues to work for the team as a field agent.
