4. Daredevil
Matt Murdoch is an attorney-at-law who was blinded as a youth in an accident involving some bio-waste. As a result of this disability, he honed his remaining senses to the extent that he had a "sonar-sense", which allowed him to perceive his surroundings (I was going to rule him out of this list on the basis that it could be considered a superpower, but then I remembered a very inspiring real world video that I'd seen of a young blind boy who could do exactly the same thing - for example, by clicking his tongue, he was able to identify the whereabouts of a basketball hoop and could score baskets as a result). After the accident, Murdoch made a silent promise with his father to "stick up for the long shots". His father was then killed soon after and at that moment he vowed to seek justice. At night, Matt becomes Daredevil, and takes justice into his hands. He was a skilled martial artist who also used his trusty billy club to take down criminals - including the sharpshooting Bullseye and the towering and formidable businessman and crime lord the Kingpin.
