HEROINE HEADCOUNT: THE RIDER OF THE PAINTED STALLION

Of all the live-action heroines I'll touch on here, this character from the 1937 serial THE PAINTED STALLION may be the most obscure.

She's a woman of mystery for most of the serial: garbed in war-chief regalia as she rides around the range on her piebald mount, fighting bad guys with her sole weapons, arrows that make a weird whistling sound, though they're otherwise just normal arrows. In the serial's final chapter, it's revealed that "the Rider" (Julia Thayer)-- who is never given any other name-- is probably a white woman taken in by a Native American tribe, and thus is no more a genuine "Indian" than Elizabeth Warren.
