"Superhero Alter Egos" on Jeopardy!

This week the Jeopardy! game show had a category about comic book characters, but the contestants did not do very well in it. One player did answer correctly that Bruce Banner is The Hulk but nobody knew the superhero identity of Oliver Queen or Barbara Gordon or Ben Grimm. Isn't that a shame?

I believe that Christine Valada would have known all of those clues (and many more).
