Catman, Post-Crisis Thomas Blake. He is not Batman, he's something else, and something beautiful at that. The story told in Secret Six of how he was a washed-up copycat who managed to make the best of a second chance was fantastic. He overcame Bronze Tiger, gave Batman the most charming "Get over yourself" speech ever, and led a team of supervillains on epic quests.

The Court of Owls. They were Snyder's best creation, in my opinion. One of the best of the New 52 as a whole and best Bat-villains ever. Their advent gave us Calvin Rose, one of my favorite New-52ers. The fact of the matter is that The Court's operations could hold down their own book with the right writer.

This isn't definitive, just to give an idea. I'll add more, make edits later
