I don't know that I ever would have devoted a post just to BULLETGIRL, as she was the somewhat mediocre sidekick to BULLETMAN, who was no great shakes either, albeit more popular than a lot of Golden Age heroes.
Like most sidekicks, Bulletgirl got clobbered a lot, but she does have some decent scenes slugging it out with villains.
And here she is teamed with Mary Marvel in a 1970s story by Don Newton.
