15. Iron Man

When Tony Stark has a Hulk on his team, he can rain down a ton of damage from the skies. Otherwise, he still does that but it’s a lot less impressive. Iron Man can be a real pest in the right hands, but his air-based playstyle leaves him more static than you might think. A good hitscan hero can ground him pretty easily and even in the best circumstances, he often has to choose between damage output and the slightest mobility. It makes him a well-balanced hero in the grand scheme of things, but it also means that one of the smartest men in the Marvel universe is constantly leaving himself open to anti-air fire.
