I'd go with Thanos, he's way cooler than Darkseid!

And Black Panther would be really cool, too. I'm kinda missing that book!
Another one I'd like 2 see would be Captain Marvel (that makes 2!)

, who is about to be cancelled 2!

I sense a pattern! Nah, he'd likely be bored to death in the empty DC "Universe". Space, that is!
