Premiering in "Green Lantern: New Guardians Annual" #1, Caul is a deep undercover Green Lantern operative that works in the Tenebrian Dominion. He unwillingly helps Carol Ferris and the New Guardians attempt to petition Lady Styx to send aid against the Third Army. For betraying them, the New Guardians leave Caul behind and he is forced to become part of a reality program called "The Hunted", stripped of his powers and with his discharged power ring embedded into his chest. Caul stars as part of an ensemble cast of spacebound DC characters, including the Blue Beetle and a new Captain K'rot, in the "Hunted" main feature of "Threshold". Caul received his Green Lantern power ring after he shot and killed its previous bearer, unsure himself why he was then chosen. Caul is able to save Sh'diki Borough on the planet Tolerance after it had been bottled by Brainiac. Caul is later informed that "The Hunted" has been cancelled and offered the lead role on a new show, "Team Cauldron", with the rest of his friends and "Hunted" competitors. Caul agrees to the role, having his power ring re-embedded into his chest. He is granted a meeting with Lady Styx to finalize his new role. However, as soon as Caul materializes at her base, he is killed by multiple gunshots, as planned by Colonel T'omas T'morra. In a glimmernet commercial, it is shown that T'morra replaces Caul in the proposed new show. However, Caul is shown alive later, along with Captain K'rot in tow, when the planet Telos manifests during the 2015 "Convergence" storyline, investigating it alongside Superman, Supergirl, Guy Gardner and the Red Lanterns.
