   Summary

   Tony Stark was just doing his best to do the right thing.
   It isn't his fault that his new teammates had no idea that he was actually happily married to the world's most badass wizard.

   Harry Potter-Stark is really tired of people trying to take advantage of his husband and will happily put them in their place if necessary. Being Heroes will not save anyone from Harry's wrath if they mess with Tony.
