Batman (Arkham Knight 1989)
Created by Bob Kane and Bill Finger in 1939, Bruce Wayne is a billionaire businessman, playboy and philanthropist, and witnessing the murder of his parents as a child has traveled the world, trying to understand the criminal mind. He trained all kinds of martial arts and combat techniques, seeking physical and intellectual perfection. He created a uniform based on something that frightened him as a child: bats. He wanted the bad guys to share the same fear. And so he began to fight crime.
Unlike many other superheroes, Batman has no superhuman power, using only intellect, investigative skills, technology, and a well-prepared physicist in his war on crime.
