Spitfire had often complained that having a power based around creating flame meant you faced two kinds of opponents. There were the people who burned, who were the majority. Civilians fell into this category. Unless the person with the power was amoral, which Spitfire wasn’t, this actually wound up being a detriment, because of the easy possibility of life altering injuries, death and scars. The kind of thing that brought heroes down on the villain’s head in full force. The second group was the foes who didn’t burn. People in armored suits with enough covering, people with forcefields, people with foreign materials either forming or surrounding their bodies, the list wound up being fairly long.
