The Flame Shield was an orb-like shield of fire that was contained inside a red, see-through capsule.
It appeared to be either made by or worked on by Hope Kintobor. After Dr. Eggman invaded Central City looking for his traitorous lackey, Snively, Hope was seen working on the Flame Shield in an attempt to be of aid to G.U.N., which was fighting back against the Eggman Empire's assault. After Snively appeared before Hope and almost recruited her, she realized he was still evil, and so she activated the Flame Shield by breaking the capsule with her hand, resulting in the shield covering her body. It protected her from the device that he threw at her, and after he ran away, it was still active. The shield was no longer activated by the time E-123 Omega approached her to comfort her; however, it was seen activated while he was walking towards her. (SU: #38)
