(Iron Man: Well, if you say it's more advanced, then by all means I guess I'll just surrender my- TANK MISSILE!) Careful, man! That's a brand new suit here!
Who: Obidiah Stane/Iron Monger
Source: How Iron Man Should Have Ended
Note: In the fight between Iron Man and Iron Monger, Obidiah launches upward with his rocket boots after announcing he had upgraded the original Iron Man suit, despite the slow take-off speed. He then says to Tony that he is certain his suit is far more advanced. Snidely, Tony fires a missile straight at the Iron Monger suit, blowing it up. While discussing it with Superman and Batman at the "Super Cafe" he stated that his reasons for killing Obidiah were the fact that Stane tried to kill Tony twice, and by throwing a villain in jail, all that results in is them breaking out and swearing revenge.
