Mary Walker aka Typhoid Mary from Marvel Comics. This is based on her redesign from the Bendis/Maleev run.

Triggers: typhoidmary, red hair, long hair, facepaint, jacket, harness, pants, asymmetrical clothes, tattoo, fishnets

You can also use short hair and headband for an alternate look. The facepaint doesn't seem to work very well on this one, unfortunately.
