Roxxon eventually re-integrates Dearborn's energy form, intending to use him against "Stratosfire", a former female Roxxon employee with abilities almost identical to those of Sunturion. Originally the corporate symbol for Roxxon (as Iron Man is for Stark International), Stratosfire turns against the company when a close friend is murdered for speaking with Tony Stark (Iron Man's alter ego). Sunturion locates Stratosfire and activates her "Zed Control": a Roxxon-implanted self-destruct device that dissipates Stratosfire's microwave energies and reverts Dearborn to his human form.
