Man, I liked your write up and all but you wound me. I only got this game AFTER they added Zatanna in since she's my favorite DC character. Fuck Darkseid, Zatanna is where it is at. Zatanna has helped out the Justice League several times and if she wanted she could literally be the strongest one. Her power is magic. Literally. She can do pretty much anything because she has the power of magic. The trick is she has to say all her spells backwards (which is why her movelist has her moves backwards) and her crippling weakness is that she can be defeated simply by covering her mouth. People like to harp on Superman for being perfect or whatever but Zatanna literally has the power to do anything she fuckin wants so long as she speaks backwards. But as per comics her powers are determined by the writer at the time but just know that Zatanna fuckin' rules and if she were more popular she'd be the magical Superman.
The DC universe should always ask if a problem in a comic could be solved faster with input from Zatanna and the answer will always be yes.
Zatanna was added as DLC because she was the most desired, as per a poll of popular requests compiled and organized by Ed Boon. I'm happy she made it, as I was one of those yapping at Boon to include her as a download.
