There are thousands of reasons why some heroes catch on with the public and some simply do not. In the comics, Nightcrawler was one of the most popular "B" list characters ever, yet in the second X-Men movie he was poorly received. The same thing happened when Ben Affleck put on the Daredevil costume years ago to the dismay of most Marvel fans.

Yet the Vision can come alive in the second Avengers movie, amid an entirely new storyline, and fans love the guy. Nobody even objected to the fact that they killed off Jarvis, and then had the actor who was the voice of Jarvis play the Vision, which means the original Jarvis from Iron Man will probably never return.

Fans are fickle, so there may be a dozen reasons why these heroes have been so incredibly underrated over the years. In this list we take a look at whom these underrated characters are, and why they may be a bit overlooked.
