Favorite Female:
Miss Fortune
Favorite Inhuman:
Nocturne
Miss Fortune's character, as cliche as it is being a bombshell femme fatale, is still a great example of a strong woman because she dealt with a traumatic event and didn't let it hold her down. She instead let it be inspiration for becoming one of the most feared and respected bounty hunters in a city where the laws are less than enforced.
Nocturne I love because he's a lot like Freddy Krueger if he were restrained. His abilities of fear are used much the same way while he knows that, if given the chance, he could dig into your mind and find whatever you fear no matter how much you've hidden it.
The reason I don't include any male champions is because I don't have any favorites there. There's a few whose stories are okay and there's a few I'm willing to play, but none of them as characters really spoke to me.
