"Nope! I know who I know... and who I don't know. And I DON'T know her."
Around September 2019, he escaped from the colonies by participating in a Moonbus hijacking and found employment as a chef at the White Dragon. He later was one of the perpetrators of an animal murder case at Runciter's.
Ray McCoy's investigation
Ray McCoy's investigation at Runciter's revealed clues indicating two suspects, one large and hobbling suspect and the other with a long, almost graceful gait (Zuben and Clovis, respectively). Other clues found near Lucy Devlin's desk revealed a receipt from Howie Lee's restaurant, prompting McCoy to take his investigation to Chinatown.
When McCoy arrived at Howie Lee's, Lee told him that Zuben was a new chef that had only worked for him for a couple of months. McCoy went out back to interrogate Zuben about Lucy, and the latter ended up attempting to escape. Before he fled, he dumped soup on McCoy in an attempt to slow him down.
After chasing Zuben through a back alley into an abandoned warehouse, McCoy reached a locked door. Zuben dropped from the ceiling and approached McCoy with a butcher's knife.
When McCoy returned to his apartment, Zuben ambushed him.
After retiring Zuben, McCoy picked up Zuben's war photo from his corpse.
Zuben is a confirmed replicant in all scenarios. In game, the only other "replicant for certain" is his boss, Clovis.
