A: This might seem like a strange answer, because the character is not that well known, but I would say the Horned King in The Black Cauldron. For years before that film came out, many Disney animated villains tended to be funny villains; one would tend to laugh at Captain Hook or Cruella De Vil or Madam Mim or Prince John or Madame Medusa. The Horned King was the first in ages who was truly evil.
