Microwave Powers: Stratosfire was given the power to utilise microwave energy for a variety of effects. She can fly, project energy blasts, teleport herself and passengers, transform her body into microwaves, and absorb energy from elsewhere.
Sandy Vincent was a political science graduate who got a job as a secretary at Roxxon Oil alongside her college friend Babs Bendix, though neither felt fulfilled in their jobs. Sandy, however, was scouted by Roxxon's research department. They wanted to use technology to give her superpowers, and she agreed. However, they also implanted her with a device called the Zed Control that would enable them to eliminate her if she became a problem or outlived her usefulness.
Once given her abilities, Sandy became a super-agent for Roxxon, taking the name of Stratosfire. Publicly, she improved the company's public image by performing heroic acts, but secretly she used her powers to sabotage Roxxon's business rivals.
