Batman and Deapool are awesome. But my vote is currently stuck between Spider-man and Hellboy.
Spider-man would probably be my overall favourite, as i grew up with him, and he has the traits of a character people can relate to, has had some brilliant stories, some of the best villians and two and a half of the best Movies.
Hellboy is my current favourite, because he is just a breath of fresh air. He has the dark surroundings and mystery of his orgins, gets a lot of action and takes no crap from anyone. i love how he is just expressionless at most of the weird junk that gets throw at him, and his use of the word 'crap' and 'sonnova' is wellplaced and hilarious.
My top five are currently:
1.Spider-man
2.Hellboy
3.Batman
4.Deadpool (thought Technically an anti hero)
5.Rorschach
Least Favourite:
Superman - agreed, too much power and not enough personality.
Jean Grey - Whine Whine Whine Wimper...
and thats all i can think of...
