After an accident that left her left arm burnt, Maya Hansen approached Tony Stark about working on nanotechnology to regrow injuries. Liking the sound of it, Tony funded "Project Extremis" and took part in the design process. The initial tests of Extremis proved to be effective, and Maya began adapting it. With Tony's permission, she turned it into "the key to super soldiers", which became a success.
