I think some of the best heroes are those that we classify as "anti-heroes". Those who get caught up for one reason or another. Those who walk that fine line between justice and crime with a dark past. My top 10 (have a lot of free time today):
1.Batman...No powers. Basically it all started from revenge (The murder of his parents). The most feared man in the DC universe. Entrusted by Superman to be the one to put him down if he ever goes rogue.
2.Spawn...Received his powers from hell and is basically caught in the war between heaven and hell. Kicks alot of demon a** and he just doesn't give a s**t. Uses his powers or guns as he was a commando in life.
3.Daredevil..No powers.. Blind, with heightened senses. Been know to go a little too far.
4.Ghost Rider...Received his powers from Hell and now fights for redemption.
5.Spiderman.....Border-line anti-hero...Gifted but flawed with tremedous person problems. Does it out of sense of responsiblity
6. Cyclops...Mutant outlaw with woman problems (too many different ones), and cool red glasses. One of the 12 most powerful mutants.
7.Wolverine...Mutant who Kicks a** and always goes too far.......
8. Catwoman....Yes Catwoman. Was a member of the JLA on Batman's (just one of his many girls)request. True "anti-hero". Save the poor and rob from the rich. Dark past, plus one of the sexiest (drawn that way) characters in comics.
9. WonderWoman...Recently became a "anti-hero" after showing a "whatever" it takes attitude recently and killing a major DC villian. A Top 5 character in total strength in DC Universe, plus she is always drawn with a nice rack.....
10. Deadpool...Anti-hero..Bad-a** mercenary. Cross between Wolverine and Spiderman. Only power is healing factor like Wolverine.
Honorable Mention: Moonknight (marvel's version of Batman, not as cool, but he goes too far)
The Huntress (one of Batman's girls. Sexy, violent and she always goes too far). Green Lantern, Hal Jordan (was good, turned bad, but saved the world and is good again, plus he kicked Superman's ass). Emma Frost, The White Queen (Former villian now an XMEN. Likes to F**k with men's minds. One of the sexiest outfits in comics. Recently seen in Cyclops' bed)
