I disagree with having Atrocitus. It is like having Two-Face as a main villain on Arrow. The only relation to Supergirl he has is the fact that she joined the Red Lanterns ONE time. Best choice they could choose is Brainiac. After all, one of the cities of Krypton was taken by Brainiac. They could definetly do an emotional story for Supergirl out of that.

Other than that, the other characters are good choices. Batwoman is who i want the most. I NEED Maggie with Batwoman.
