You have no idea who that is do you? Wait, check that. You have no clue how the Iron Man comics ARE do you? The whole point in the comics is Tony Stark trying to right the wrongs of his family and people that hate him try to take his technology to beat him. Jesus fucking Christ do some damn research before making a stupid comment like this.
The guy with the "glowey circle energy thing" as you said is Ivan Vanko aka Whiplash. Ivan Vanko is the son of Anton Vanko (in the movie)... in the comics, Anton is the Crimson Dynamo who outside of maybe The Mandarin is one of Iron Man's primary antagonist. Think, Magneto essentially. Mickey Rourke is playing Ivan which is fucking badass and Whiplash is fucking insane in the comics with what he does.
