The character first appeared in Action Comics #844 (December 2006) and was created by Richard Donner, Geoff Johns, and Adam Kubert.
An adaptation of the villainous Lor-Zod appears in the animated series Young Justice, voiced by Phil Morris.
Another interpretation of the character appears in the animated film Justice League: Gods and Monsters, voiced by Benjamin Bratt.
He first appeared in Action Comics #844 (December 2006), in the story arc Superman: Last Son, and was created by Richard Donner, Geoff Johns, and Adam Kubert.
A new version of Lor-Zod was introduced in 2017 during DC Rebirth in the Action Comics series during the "Revenge" storyline, this time as a villain.
To aid him, Superman worked with Batman to develop an implant, concealed within a wristwatch, that used red sun radiation to block Chris' powers until he learned how to control them.
While the watch was being created, Chris befriended Tim Drake, the current Robin, who treated him like a younger brother and offered to show him some gymnastics.
[4] Eventually, the wristwatch failed, due to it being calibrated on the metabolism of an adult Kryptonian, and the built-up energies exploded, wrecking Clark and Lois' apartment.
[7] Superman escaped with Mon-El's aid, and then sought an alliance with Luthor to defeat Zod, who had captured a large portion of Earth's superhero population.
Afterward, Mon-El, asked by Superman to look for the child in the Zone, reported that he was unsuccessful so far although he knows that Zod does not have him, but vowed to continue searching.
Since the belligerent government of Alura and Zod had tarnished all Kryptonians' reputations on Earth, Chris and Thara decided to act as a new Nightwing and Flamebird duo (since Dick Grayson, the previous Nightwing, became the new Batman), at first with simple cloth masks, then with fake power suits, to obscure the origins of their powers.
[11] After a brutal attack by Ursa, Thara is left gravely wounded by a Kryptonite knife and Chris is forced to bring her to Lois for medical assistance.
The four battle, with Chris and Thara quickly gaining the upper hand; however their fight is interrupted by Codename: Assassin and what seems to be a gang of "ogres".
[14] After the two receive a hero's thank you from a crowd in Hollywood, Thara notices that one of the girls gave her phone number to Chris.
[20] Jax-Ur's theft of Chris' DNA and its purpose is soon revealed as he unleashes a replica of the Kryptonian deity Rao to trample and rampage across Earth.
While he is there he can only observe as Thara, Lois, and other heroes battle against Rao but fail to inflict any actual damage, only Wonder Woman managing to hold her own.
Now a fully fledged avatar of the Nightwing entity, Chris is able to fight Jax-Ur (revealed to be the Kryptonian deity the Builder as well) along with Flamebird on even terms.
Once the Rao crises is dealt with both Thara and Chris regroup with the other heroes; they kiss and flee to avoid any more hostilities with the locals.
[21] During the War of the Supermen event, the solar system's sun was turned red by the combined efforts of General Lane and Lex Luthor.
He, his father and the Eradicator eventually come into conflict with Green Lanterns Kyle Rayner, Mogo, Guy Gardner, and Hal Jordan.
A son of General Zod appears in Justice League: Gods and Monsters, voiced by Benjamin Bratt.
He later becomes his universe's version of Superman and the leader of the Justice League, but faces opposition due to his brutal methods.
While foiling Will Magnus's plot to subjugate the world using nanites and learning his father was responsible for Krypton's destruction, Guerra realizes the consequences of his brutality, earns back public favor, and considers using less lethal methods.
