[Discussion] Useless Question: What do you think is the second most important character in Batman Mythology?

I think it's kind of obvious that Gordon and Catwoman aren't as important as the other three, but I thought it would be interesting to mention them since Selina is Bruce's main romantic interest and Gordon plays an important role in many Batman stories.
