15. Iron Monger (Iron Man)
The Iron Monger armour was worn by Obadiah Stane - Tony Stark's former mentor and a friend of his Father Howard's - who turned on Tony in order to gain control of Stark Industries. The armoured suit in question utilised Stark's own technology, but improved on it to make it stronger and was much bulkier than the sleek design of Iron Man's suits. It possessed vast super-strength and durability, flight capabilities and weapons that included a minigun, a rocket launcher and a shoulder-mounted missile - all of which could be aimed at a potential target using a highly sophisticated targeting system. Its only downfall in a fight against Iron Man was its lack of a way to deal with freezing up, which Tony Stark used to his advantage by drawing Stane high up in to the sky where the temperature dropped dramatically.
