Daredevil: Young Matt Murdock was blinded by chemicals as a child but the chemicals that took his sight also enhanced his remaining senses. Able to hear a heartbeat from a mile away, now he practices law by day and fights crime by night.

Punisher: Dispensing his own brand of vigilante justice, Frank Castle is often at odds with costumed heroes, and even tried to eliminate Spider-Man in the early days of his career. Most of them steer clear of this ex-soldier for their own safety.
