Gon (Everybody just underestimates him since they always say Killua is stronger, and that he has a long way to go)
I don't think there is any main character that is underrated.
People either think he's awesome, or sympathize with him and want him to be better than the guys that are better than him.
No one ever completely ignores the main character.

Since this is like the 100th time he was mentioned in this topic, I think we can take him off the list.
Enel had an amazing design, especially with the earlobes. Everything else about him as boring as shit, though.
Maybe, but I liked the God Complex alot more than the "Cool collected calculating" villain. and for some reason, electricity control has always been a favorite super power of mine.
I was sold based on Enel based off the fact that he was designed after Eminem alone. Everything else was just icing to me. But still, Croc and the pimpcoat are still my number one.
I always thought that was a grasping fans conclusion after reading "he likes eminem" and seeing enel with his blonde sideburns.
IIRC, his first manga coloration had him with blue or pink hair or something. THe blonde was the animes doing.
