John Doe. He was Jane Doe's husband. Before becoming a Killer, he worked at Roblox Headquarters (HQ). He handled desk work and was a cheerful person who made everyone around him laugh. He had great relationships with his colleagues. He loved Jane Doe deeply. He often told his coworkers, "Jane is the greatest treasure of my life." One day, John was assigned to test some old, decommissioned code. However, that old code was still 'alive'. During the test, an error occurred, and corrupted data began to fuse with John's body. This resulted in his current form. He was then sent to the world of Forsaken by the Specter and reported missing on March 18th. Now, he encounters his once-beloved wife, Jane Doe. However, John has been manipulated by the Specter into becoming a Killer—a mere "program designed only to eliminate survivors." The Specter has altered John's vision. When John looks at Jane's face, it appears as if it has been blacked out, looking like "pitch-black noise." He cannot even recognize her name. The Jane that John sees now is simply a target to be eliminated. Additionally, John's ability allows him to erode everything he touches with black mold, possessing a destructive power that pollutes the world. He leaves a trail of contamination like footprints. He can set this contamination as traps. He can summon spikes from the ground. He also has the ability to visualize the location of Survivors.
