Who is your favorite Superhero or Supervillain ever?

Now, I have to admit, I don’t know a ton about superheros and supervillains. That’s probably part of the reason why, instead of hiring me, the science museum has elected to hire QuizzoMan. But I do have a few favorites. I am particularly fond of the Brown Hornet and the Riddler, especially when the Riddler was on the Batman show in the 1960s. That Riddler was awesome.
