1 on 1, no prep time, fight to the death, Iron Man has morals on and Killer Frost is blood lusted.
Fight takes place in a relatively crowded Central Park. Iron Man can not harm any citizens on purpose and must try and protect them while battling Killer Frost.
Who would win and why?
p.s. sorry if this battle is a mismatch, I don't really know that much about Killer Frost
