One of the sets of characters that I have always been interested in has been the Earth 3 set of Crime Syndicate villains. I always wondered what drove the Owlman character to adopt an owl as his symbol rather than a bat (which would seem naturally more dark and evil than an owl.) Now however after reading the Court of Owls storyline going on, it gives a bit more depth to that character's potential back story and position in his life.
I'm always excited to see these characters show up and have been hoping to see them eventually with this "new" bunch of characters and how they would all react. Now I'm especially excited to see the reaction between Batman and Owlman.
