Superheroics isn't the only thing heroes are all about. They have day jobs, too. Not everyone is like Batman, who's a multi-millionaire from birth. Superman, as Clark Kent, has to make ends meet as a reporter. And there are some heroes whose day jobs are as unpopular as the lawyer job. There are a few of them, and while they battle it out in the streets, they also battle in out in courtrooms to keep the crooks locked up. Come to think of it, with how small the list is, we probably need more superhero lawyers - although some say there are perhaps too many lawyers in the U.S. already.
The most well-known superhero lawyer is of course Matt Murdock, a.k.a. Daredevil. Blinded but gaining radar sense because of an accident involving an AIM truck releasing radioactive materials, Matt aced law school and became a hard-driving attorney. He also had detective skills, and as a lawyer, represents fellow heroes and helps them out in legal matters.
