Vigilante

A complex character who bypasses traditional legal authority to enact self-appointed justice, driven by an absolute desire to redress personal or social wrongs.

The thrill of seeing justice delivered outside the system, the moral ambiguity of a flawed hero fighting for what they believe is right, and the tension of operating in the shadows against powerful forces.
