Zachary Zatara
Zachary Zatara is a fictional character in the DC Universe. Zachary is a descendant of the Homo Magi just like his cousin Zatanna and uncle John Zatara. He first appeared in "Teen Titans (vol. 3)" # 34, and was created by Geoff Johns and Tony Daniel.
Zatanna
Zatanna has had various romantic relationships with fellow DC characters, including John Constantine (with whom she practiced tantra) and Doctor Thirteen. Zatanna had a flirtational relationship with her fellow Justice Leaguer Barry Allen / The Flash shortly after the death of his wife Iris. She has a strong friendship with Batman due to their shared (retconned) pasts. In "Detective Comics" #843 and #844, Zatanna and Bruce briefly discuss the possibility of having a more meaningful relationship. Both later concede that Bruce is too devoted to his cause as Batman to give her the relationship she wishes for, but the pair reaffirm their bond as close friends.
