She was definitely a favorite of mine from the great All Star Squadron series. Great character with great powers.
A couple more pages from All-Star Squadron #5 (January 1982):
One of my favorites from that era! I'm a sucker for a character with a cool visual, and a fiery one who isn't totally obscured by her flames (like the Human Torch over at Marvel) is a great one. (And it's a pleasant surprise how much better the male Firebrand's costume looked on her, with a few tweaks.)
One of my favorites from the All Star Squadron! I wish she were still appearing in stories. Miss many of those characters.
