"What do you care about some leggy dame in nylons? Or have I answered my own question?"
Ladies and Gentlemen, making her stage debut in the gallery: Zatanna, the Mistress of Magic!!
Born to the great Italian magician, Giovanni Zatara, Zatanna was a member of the Homo Magi, humans who were able to practice magic. Zatanna became quite the prodigy, and during her teenage years, even became a good friend of the young Bruce Wayne, who trained under Zatara in his path to become Batman.
After Giovanni's death, Zatanna became a talented stage magician in her own right, even reuniting with Bruce after he told her that he was Batman. Yet when the sorcerer, Felix Faust threatened to damn everyone's souls to Hell, Batman and Robin called upon Zatanna and Jason Blood, the Demon Etrigan, to gather a handful of supernatural heroes to stop the threat. Zatanna took charge of the team, along with her old love life, John Constantine, and after defeating Faust, formed the Justice League Dark. Though soon after many battles, Zatanna earned herself a spot in the Justice League proper!
For Zatanna's look, I wasn't going to go with her appearance from the upcoming Justice League Dark animated movie, since that's not how a lot of people remember how she looked. Though I did like the sleeveless look that iteration of her was presented in. So I decided to go with sleeveless stage magician look. I had to give her the top hat, collar and bowtie, along with the cuffs, gloves and corset, since that's how she appeared under her jacket in some images I saw of her.
