Yotun initially escaped from the Off-world colonies in 2017. Sometime after arriving in Los Angeles, Yotun sought assistance from Mr. Malcolm to escape, he learned that Malcolm had actually sold him out to the Los Angeles Police Department Blade Runner Unit. Blade Runner Ash accepted the assignment, confronting Yotun at Malcolm's shop. Yotun managed to kill Malcolm and throw his body onto Ash, allowing him to disarm her and escape, telling her she would never see him again.
Yotun, a Nexus-6, managed to extend his lifespan by accepting lifespan donations from fellow replicants, managing to survive well into 2029. He amassed a group of replicant followers who established a base inside a waste treatment plant hidden by a massive garbage heap.
In 2029, Ash pursued a replicant who said "Yotun redeems" before jumping to his death. This prompted Ash to rediscover Yotun's files. Learning of Ash pursuing him once more, Yotun tasked Lelia with finding the Blade Runner.
Yotun and Kalia later observed tanks containing replicants, comparing his own legacy – one of redemption – to Eldon Tyrell's – one of profit. As Yotun grew exhausted, Kalia suggested he receive a rejuvenation. After receiving such from Ducasse, Lelia informed Yotun that she had found Ash, to which Yotun requests she bring the Blade Runner to him.
Yotun and his followers later arrived at an airship, where a soiree was to be held by the Los Angeles elite, celebrating the Sepulveda Sea Wall construction progress. After eliminating the front security, the group gained access by using Hyman Bask's eye, procured by Ducasse.
Upon gaining control of the airship, Yotun held the city's elite – including Mayor Chen – hostage, pointing out what he saw as their hypocrisies and demanding control of the Sepulveda Sea Wall, which he claimed to have been built by replicant hands, arranged by himself. He then detonated explosives planted upon the wall and left the airship. Upon destroying it as well, he remarked "Los Angeles is dead. Long live Los Angeles."
During their return, Yotun commented on the city's inhabitants, wondering if they were even aware of how much their lives would now change. His thoughts were interrupted by a pair of police spinners who attempted to stop the group, but Yotun managed to disable one and hijack the other.
Yotun flew back toward the base, finding Ash climbing through the heaps of garbage. As Ash attempted to find a weapon, she was disabled by her spine, allowing Yotun to capture her. He took her back to the base, where he summoned a group of replicants she had once retired to show themselves to her. In what he saw as an act of mercy for retiring these replicants, he had Ash placed inside a replicant tank, promising "new life" and hoped it would bring her clarity.
Yotun was then brought to Silka, Dyson, and Farhad, a group of replicants who claimed to have turned on their leader Freysa, who they had brought as a hostage. This, in addition to having shut down power to five sectors, was their way of showing support for Yotun's cause. However, Yotun was skeptical of them, believing that this was perhaps a ploy to rescue Ash, who was Freysa's lover. Nevertheless, Yotun decided to play along, but brought Freysa with him for an important mission.
He took Freysa to the LAPD headquarters, where the group had begun their attack. Freysa attempted to convince him it was a suicide mission, but Yotun insisted that the police were no match for the liberated replicants and that this uprising was Eldon Tyrell's true legacy. Once the police began retreating to ground level, Yotun reminded Freysa of her rescue Mesa Echo Erebus, revealing himself to be one of her rescuers. Her referred to their re-encounter as a miracle and insisted that she belonged with his group.
