Suggested by Sonic Crimson Dynamo is easily the most underrated villain in all of Marvel. I always thought he would have been the most popular Iron Man villain because of how similar the two characters are but it never happened. While Dynamo never got any kind of armor that could compete with Iron Man at his best, he still has a good amount of firepower. I believe Black Spider would very quickly be overwhelmed against such a powerful opponent and would ultimately have to accept defeat. Dynamo will blast away at the spider until he loses. Crimson Dynamo wins.
