Xero
A DC Comics superhero and antihero series about a technologically enhanced covert operative whose work forces him to confront his conscience.
Last updated August 21, 2026
Overview
Xero, also styled as Xerø, is a fictional superhero and antihero published by DC Comics. The character first appeared in the self-titled comic Xero #1 in May 1997. The series was created by writer Christopher Priest and artist ChrisCross and was designed as a relatively self-contained property rather than a conventional extension of DC Comics' wider superhero continuity. The central character is Coltrane "Trane" Walker, an African-American professional basketball player who maintains a secret life as a technologically enhanced operative. Under the codename Xero, he acts as a highly capable "closer" for espionage operations. His assignments involve resolving sensitive situations and, in some cases, eliminating witnesses. To protect his identity and operate in environments where his real appearance would be unexpected, Walker uses technology and disguise to present himself as a masked, blond white man. This premise gives the series an unusual identity-focused angle. Xero is not simply a costumed hero responding to conventional supervillain threats; he is an operative whose professional role involves morally compromising violence. The narrative follows his gradual development of a conscience and the conflict between his capabilities, his assignments, and his emerging resistance to the consequences of his work. DC Comics published twelve issues of Xero across 1997 and 1998. Although the title was intended to continue, sales were weak and DC cancelled the series. Christopher Priest brought the story to a conclusion in the final issue rather than leaving the published run entirely unresolved. The character had limited interaction with the broader DC Universe. Doctor Polaris appeared during the Genesis crossover event, but Xero did not become a recurring participant in other DC titles. The property also had an unusual rights structure. Although the characters appearing in the book were owned by DC Comics, Priest co-owned the copyright in the stories and artwork. This creator-involved ownership arrangement distinguished Xero from many standard publisher-owned DC series. Following the cancellation of its original run, the title remained a niche work associated with Priest's comics bibliography rather than an active, regularly published DC franchise.
History
Xero was created by writer Christopher Priest and artist ChrisCross for DC Comics. The character first appeared in Xero #1, published in May 1997. The series presented Coltrane "Trane" Walker, an African-American professional basketball player who secretly worked as a technologically enhanced covert operative. Using the codename Xero, Walker served as a "closer" in espionage operations, a role that could include tying up loose ends and killing witnesses. His field identity involved a masked disguise in which he appeared as a blond white man. The title's principal dramatic concern was Walker's moral development. Rather than depicting an uncomplicated heroic figure, the series placed its protagonist in the position of an operative whose technical abilities and professional obligations were connected to ethically troubling missions. The story explored his growing conscience and the tension between his public identity, his concealed profession, and the violence carried out under the Xero persona. DC published twelve issues during 1997 and 1998. The title was initially intended to continue, but weak sales led to its cancellation. Priest concluded the narrative in the final issue, allowing the published series to reach an endpoint despite its short run. Xero remained comparatively separate from the established DC Universe. Doctor Polaris made a guest appearance in the Genesis crossover event, but Xero did not appear in other DC comic books as a continuing crossover character. The series also had an atypical ownership arrangement. The characters featured in the book belonged to DC Comics, while Priest co-owned the copyright in the stories and artwork. This partial creator ownership gave the title a different legal and creative profile from a wholly publisher-controlled DC property. After the 1997–1998 run ended, Xero remained primarily known as a limited DC Comics series and as an early work in Christopher Priest's comics career.
