Gargantus - An outer space robot who appeared in the form of a. Now if they bring in like Dreadknight, Blizzard, the Beatle - who WAS also a Stark employee - and a spider-man villan as well. Firepower - Suited villain who initially defeats Iron Man in the Armor Wars storyline. Whiplash could be goofy or cool, depending which route they go, but eh not my fave of his rogues gallery. Heck even his daughter created a lot of mayhem in the superhero community. So Hammer would be cool - since he employed A LOT of supervillans and the like over the years. Now, from what I recall Justin Hammer was also a big time Stark rival - basically MORE of an enemy than Stane ever was - even though Stane broke the original SI and made a LOT of trouble - including selling off armor secrets to others which led to Tony and the 'Armor Wars'. If done today the 'original' Black Widow look would be more Spanx and a dress than spandex) Titanium Man was another Russian invention too, but with a more aggressive mission, make Iron Man look weak and beat him. (Originally she was just a sultry spy chick in an evening gown playing cat and mouse games with Tony Stark not a spandex clad femme fatalle. Which also led into Black Widow being given her costume and additional gimmicks. That immediately led into the Black Widow and one of her thugs taking the armor and capturing Vankov, and Vankov died while taking down the thug. Crimson Dynamo came first, as a Russian scientist who created his own suit of 'mighty electrically powered armor!' who eventually defected to the USA after realizing his Russian 'superiors' were going to sell him out. Well as I recall most of the early Iron Man stories from both Tales of Suspense (the title he debuted in) and Iron Man featured most of these names being dropped.
