Or superheroes that were filmed into a huge blockbuster movie adaptation.
For that matter, the only comic books are superhero comic books and possibly manga.
For Superman there's Lex Luthor and...uhhh, maybe Brainiac? (And, briefly in the 1990s, Doomsday.) General Zod (from the second movie), or rarely some other Phantom Zone villain, might get the odd mention.
Batman has The Joker, The Penguin, The Riddler, Catwoman, Mr. Freeze, Two-Face, and Poison Ivy. (The Scarecrow might get mentioned.) Before 1990, bet heavily on it being one of the first four.
The only Ninja Turtles characters you can count on most people knowing are either the ones who appeared in the movies (the Turtles themselves, Master Splinter, April O'Neil, The Shredder, Casey Jones, Baxter Stockman) or those who had prominent roles in the animated series (all of the above characters plus Krang, Bebop and Rocksteady). Only diehard fans remember the Triceratons, even though they featured prominently in the comics.
All of this is assuming people even realize the Turtles were originally comic book characters. People are likely only familiar with the cartoon versions and would be surprised how brutal the comics can be.
Dick Tracy villains: Big Boy Caprice (and just because he got an adaptational upgrade in the movie), Flattop, Pruneface, a handful of others (maybe The Brow and/or Littleface), and The Blank (who was not Breathless Mahoney in the original strip)
