History
While serving prison time for a crime he didn't commit, former gang member Carl Lucas volunteered for an experiment that gave him enhanced strength and unbreakable skin. He promptly used his new abilities to escape prison, returning to his boyhood streets of Harlem.
Rather than returning to crime, he took the name Luke Cage and became a mercenary "hero for hire," using his powers to help anyone who could afford his asking price. More recently he has served with distinction on the New Avengers.[1]
