The Zatanna DLC for Injustice: Gods Among Us is out today, and so is this video telling us the abbreviated version of her long-ish history.
If you're a comics reader maybe you'll take a moment to join us in pitying whoever had to try to cobble together this 'history' of a character whose entire life got retconned a couple of years back. If not, please watch the video and pretend you never read that last sentence.
