I was gonna do DC’s JLA member Ice, but then I remembered that she’s really, really boring.
So I looked around a bit. There aren’t very many cool female characters whose name start with “I”. Irma Geddon from Top 10 was the only good choice until I remembered this chick.
That’s right! It’s Wu Ao-Shi, the Iron Fist of 1545 AD! Also known as The Pirate Queen of Pinghai Bay. Thanks, Matt Fraction, for making an awesome character whose title starts with “I”.
