Christopher Kent (Lor-Zod) is a fictional character, a Kryptonian in the , who first appeared in Action Comics #844 (2006), the first part of the Action Comics story arc "Superman: Last Son". Created by Richard Donner, Geoff Johns and Adam Kubert, he is the biological son of General Zod and Ursa, and the foster son of Clark Kent (Superman) and his wife Lois Lane. Recently, this character had assumed the role of Nightwing after abnormal spurts of aging due to his birth in the Phantom Zone. Due to the resetting of all Superman related characters, Chris does not exist following Flashpoint.

When a spacecraft fell towards Metropolis, it was diverted to a relatively safe landing by Superman. After its landing, Superman was very surprised to discover a young boy inside. Echoing his own arrival in his youth years before, Superman saw that the boy was completely unharmed. The Kryptonian writings on his ship stated that his Kryptonian name was "Lor-Zod," which was later confirmed in Action Comics #851. He was taken to the east coast lab of the Department of Metahuman Affairs (under supervision of Sarge Steel) for observation.

The boy exhibited superhuman strength and could only speak Kryptonese. He did not know his name or where he came from. As with Supergirl, Superman instinctively knew the boy was Kryptonian before the tests were completed. After he was confirmed as a Kryptonian, he was immediately taken to the Department of Metahuman Affairs headquarters in Washington, D.C. without Superman's knowledge. He removed the boy from their custody, and decided, with Lois Lane, to raise the boy. Clark then contacted Batman, who used his resources to create the identity Christopher Kent.

Chris remained in the custody of Lois and Clark as their foster son. He attended the Ellsworth School, an elite private school, where he had some trouble concealing his powers, particularly during P.E. To aid him, Superman worked with Batman to develop an implant, concealed within a wristwatch, that used red sun radiation to block Chris' powers while in school until he learned how to control them. While the watch was being created, Chris made friends with Tim Drake, the current Robin, who treated him like a younger brother and offered to show him some gymnastics. 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. Clark reassured the young boy that he wouldn't be sent away, and that they would find a way to cope with his growing powers.

Nightwing (Chris Kent) has not been a contender in any CBUB matches.
