Zatanna Zatara is a figure of the DC Comics universe. She is a powerful sorceress and works as a stage magician as her cover. She calls forth her magic powers by saying her desired effect backwards.
Injustice: Gods Among Us
Zatanna is a DLC character for the Netherrealm Studios fighting game Injustice: Gods Among Us. She was specifically included due to popular request from fans, and in fact won a supposedly informal poll game designer Ed Boon ran on Twitter. Her special attacks are all magic-based, with names that are spelled backwards, as per her abilities in the comics.
Zatanna's character-specific power is an alternate fighting form in which she dons a top hat and wields a magic wand.
