Ironman and Crimson Dynamo have been enemies for sometime now. They have fought plenty of times over the past and both keep upgrading. At first The Crimson dynamo was stronger, but over the years Ironman kept upgrading and The Crimson Dynamo was forgotten. When he came back in the latest tv show he was done all wrong. Now Ironman’s armor is so thick Human Torch’s fire can barely destroy him, let alone The Melter or Crimson Dynamo. Ironman wins.
