One of the most entertaining comics in the DC New 52 is Worlds’ Finest. It’s a comic about superhero BFFs. Also it is a fish out of water story. The women are trying to find their way in the world as the readers are. On the “regular” Earth the ladies are Power Girl and Huntress, but in the Zero Issue, we get to see them in their Earth 2 roles of Robin and Supergirl. Should be interesting!
DC Comics says: “It’s the origin of Supergirl and Robin on Earth 2! How did their first mission on that world affect their situation as Power Girl and Huntress today? “
