[1] The character's reappearance in the 2000s rebranded him as a violent and unhinged backup personality of Batman, but the alien version has been revealed to still exist in the main continuity.

The story reveals that the "Zur-En-Arrh" persona is a backup personality created by Bruce Wayne in the event he was ever mentally compromised.

The Zur-En-Arrh personality is shown to be more violent and unhinged than Batman's normal persona and is dressed in a costume out of red, yellow, and purple rags referencing the one worn by Tlano.

In 2022, when Chip Zdarsky took over as the new Batman writer, he reintroduced the Zur-En-Arrh persona as having created Failsafe, a robot who serves as a contingency plan should Bruce fall from grace.

[5] Bruce's struggle with Zur and the consequences of its violent, unflinching methods remained a prominent storyline throughout Zdarsky's run.

The two Batmen join forces to defeat giant invading robots piloted by an unidentified alien race.

[9] During his travels during the "Dawn of DC" initiative, Bruce meets Daniel Captio where he learns how to create multiple personas.

[10] Batman created Zur-En-Arrh when a villain named Professor Achilles Milo poisoned his mind, and caused him to experience his fears.

While traveling throughout the Multiverse and meets multiple alternate versions of himself, which causes his mind to fracture and his Zur-En-Arrh personality to infect the other Batmen.

Regardless, Failsafe announces himself in Gotham and Damian Wayne joins with him in his crusade against crime, while Jason, Tim Drake, Dick Grayson, Barbara Gordon, Cassandra Cain, Duke Thomas, and Stephanie Brown try to find where Bruce is.

[19] Zur warns Amanda Waller to stay out of his way, and confronts Daniel Captio on letting Bruce escape.

In the modern continuity, the crazed Bruce Wayne comments that, despite the ostentatiousness of the costume, Robin had dressed this way for years, implying that it reflects the "total confidence" of the Zur-En-Arrh Batman in his ability to attract the attention of his enemies whereas the Earth Batman dresses in dark colors to attack his foes in the shadows.

This may or may not reflect a continuity between the two stories, as Grant Morrison has made efforts to treat Batman's entire publication history as his backstory.

[24] This version is the protector of Gothtropolis, works as a reporter at the Solar Cycle newspaper, is assisted by a robot butler called Alpha-Red, is an associate of Chancellor Gor-Zonn and Vilsi Vaylar, and is an enemy of Rohtul.

Depending on the viewer's choices, if Batman sacrifices himself to save Jason Todd, he will be resurrected by Talia al Ghul via a Lazarus Pit.
