Is Batman a hero?
His fans would say yes. (His detractors might say no.)
Huntress is a hero. In Earth-2, Helena Wayne (the daughter of Batman and Catwoman) FIRST becomes Robin, then later Huntress, were she battles criminals. On New-Earth, Huntress also helps Batman fighting crime (she is a member of the Birds of Prey, which is a team of women, in Gotham City, the place where Batman is).
