Jack (Mass Effect 2). I had a Praha PG with her face. Torque had her head shaved and her body full of black marks [marks of a god, long story about vampires and blah blah blah] so Jack came to my mind when I was looking for her avatar.
Source unknown to me please send credits info to Optimystique1 thanks.
Mass Effect 3 - Jack Cosplay by *Aicosu on deviantART - I hate when I see a costume that look amazing, ...but then don't recognize what it is from...cause I probably shouldn't wear it then... :(
