Is Ares generally considered Wonder Woman's main rival/#1 villain?
Like how the Joker is that to Batman or Lex Luthor is that to Superman? I'll be the first to admit that I'm not as familiar with the Wonder Woman mythos as I think I am with the other two. Based on what I saw on the old Superfriends cartoon, I was led to believe that Cheetah was the #1 Wonder Woman villain. Plus, I don't think that the old Lynda Carter TV series used that many members of Wonder Woman's rogues gallery from the comics.
