Nightingale is incredibly strong. We’re talking Thor levels of strength here (I was going to say Superman but…not quite) but she doesn’t use her strength to pound bad guys faces into the ground. No, Nightingale is the medic to the superhuman community who want to keep their secret identities…well…secret…She even makes house/rooftop calls. The strength comes in handy if any of the bad guys (who she also treats…for a price) try to mess with her.
[EDIT] Now that I’m looking at a larger image of this character, I gotta say, the shading kinda sucks. I’ll probably go back and edit at some point. Must try harder.
