She is a loyal and long-time member of the Justice League of America, and often works alongside the most powerful magic users on Earth, including Doctor Fate, Madame Xanadu, and Captain Marvel.
Zatanna casts spells by speaking her magic incantations backwards. Her powers are virtually limitless, from summoning shackles to healing others to teleporting from place to place. However, Zatanna is wary of overusing her magic and limits herself to defensive and non-lethal spells.
Did you know a simple gag is enough to halt Zatanna's magic? If she can't speak, her magic doesn't work; that's if you can manage to get close enough to her.
