There are some incredible female superheroes at Marvel, DC, and beyond. Marvel has quite a few great choices, which include the Scarlet Witch, who has exploded in popularity in recent years in the MCU, as well as characters like Black Widow, Captain Marvel, and Storm. Over at DC, Black Canary, Supergirl, and Batgirl are all great characters, but DC's best female hero is likely to be at the top of everyone's lists, as Wonder Woman is the most iconic female superhero ever. From the Invincible franchise, I think Atom Eve ranks higher than many Marvel & DC heroines.
