Zachary Zatara
Zachary Zatara was the teenage nephew of sorcerer John Zatara. As a result of his lineage as well as a sudden influx of magical energy in the world, John developed mystical abilities such as summoning objects and changing the forms of other items. Like his uncle and cousin, Zatanna, Zachary's power was dependent upon speaking command words backwards. Zachary Zatara joined up with the California-based incarnation of the Teen Titans and developed a friendship with Kid Devil.

Zatanna
Zatanna is the first name of Zatanna Zatara, a costumed adventurer and magician. She is the daugther of John Zatara and the Homo-Maji woman, Sindella. Zatanna has the ability to cast magical effects, including affecting probability, controlling weather and the transmogrification of solid matter by speaking her commands backwards. Like her father, Zatanna never bothered maintaining a secret identity, preferring instead to trick the general public into thinking that she was nothing more than a very talented stage magician. Zatanna was a member of the original Justice League of America, during which time, she embarked upon an extended search for her mother, who had gone missing. She remained with the group throughout its initial duration, including the Detroit years. Zatanna was an associate of the JLA incarnation of the League and became a member of the Sentinels of Magic.

Zatara
Zatara was the surname and theatrical name of John Giovanni Zatara. Zatara was a mystic who could effect matter and probability by speaking lines of command backwards. Zatara did not maintain a secret identity as such, though the general populace regarded him as little more than a stage magician. John married a member of the Homo-Maji race named Sindella, and through her, gave birth to a daugther, Zatanna. Zatanna followed in her father's footsteps, both as a stage magician as well as an adventurer. John Zatara joined with other powerful mystics to stop the Great Evil Beast, which represented the darkness that existed before creation. Along with Sargon the Sorcerer, John Zatara perished during this event. Since then, John Zatara's spirit has been condemned to the afterlife.

Zuggernaut
The Zuggernaut was an alien being that came to Earth and landed in Russia. It bonded its form to that of a criminal named Matvei Rodor, whereupon it evolved into a tall creature with an elongated cranium, a tough carapace and sharp claws. Guided by Rodor's emotions, the Zuggernaut attacked one of his rivals in Moscow named Soliony. The Zuggernaut fought up against Firestorm, who at this point in time was the merged essence of Ronnie Raymond and Mikhail Arkadin. Firestorm managed to drive the creature away and save Soliony. The Zuggernaut made a second attempt on Soliony's life, but this time it was repulsed by the superhero team, Soyuz.
