    He doesn’t have a doctorate but Joker is stated to be an expert chemist almost on par with Scarecrow, just different focuses.

    Ra’s Al Ghul is 600 years old, a master of multiple martial arts and languages, has first-hand knowledge of all kinds of history, and is the leader of the League of Shadows.

    And I’d be willing to throw most supernatural villains in the list too.

      It’s not the intelligence I find as interesting as the formal education prior to villainy.

        Tom Elliot was one of Bruce’s childhood friends, but always kind of a psychopath. He set up his parents murder, and then used his inheritance to go to medical school and become a master surgeon.
