Look you dumb fukks the iron man villains can't be too powerful otherwise you would have to involve shield and the other avengers. If the mandarin was too powerful and have supernatural powers then it would need to be an avengers movie. Starks enemies will be somewhat domestic. You can't give iron man the same villain you would give the hulk or Thor.
Yes you can, it just depends on which villain it is. Many of their villains cross over as it is. Stark is a genius, so if a Villain is thrown at him that he can't beat in a straight up fight with his standard armor the screenwriters can show him using his intelligence to get the win.
