Mr Doll isn’t a very powerful villain. In fact, I doubt very many people have even heard of the guy. He can use dolls to inflict pain on his opponents, but that isn’t as good as having a super powered suit to take care of all opponents. Ironman is fast enough to easily take care of Mr Doll without having to worry about the doll. A quick Unibeam will take this guy out for the count. Ironman could win in at least 50 different ways. Ironman wins.
