- "They will find us. They will devour us. We will be made whole."
- —The Cult Leader's dying words
Dead Space 3: Awakened
After the death of Jacob Danik and the destruction of the Tau Volantis Brethren Moon, the Unitologists are seemingly contacted by the Brethren Moons and ordered a massive recall of the survivors on Tau Volantis to the CMS Terra Nova. There, a group of Unitologists splintered off to form a new Church, made not of "brick and mortar, but of flesh and blood" and the Moons are coming and are "hungry". One anonymous individual became the leader and prophet of this new Unitologist cult. He and the other survivors began to ritualistically mutilate themselves, sawing off body parts as offerings to the approaching Moons.
When Isaac and Carver arrived on the Terra Nova, they experienced several hallucinations in which they saw the prophet carving off a man's hands, presumably Randall Carr and several more times throughout the ship. The prophet seemed to act as the voice of the Moons, taunting Isaac in several severe hallucinations, causing the engineer to begin doubting whether he and Carver should return home or not which resulted in them arguing.
During several of these hallucinations, the prophet displayed several supernatural abilities ranging from immunity to physical harm and teleportation. After Isaac and Carver retrieved the ShockPoint Drive, Isaac made a break for the reactor of the Terra Nova to destroy it, convinced that it was the only way to protect Earth from the Moons. The prophet appeared once more in a final hallucination where Isaac and Carver discovered that the man could be harmed if they destroy one of the Markers within the hallucination.
After destroying three Markers and shooting the Cult Leader, their connection to the Moons was broken, though he warned Isaac and Carver that their chance to warn the Earth has come and gone. When the hallucination ended, Isaac and Carver stood victorious over the defeated and the wounded prophet would continue to rant and rave. Wounded he declared that the Moons would still find Earth. Isaac could either execute the Cult Leader or let him live, but his words still came to pass. If the player spared the prophet, his fate was unknown as the ship made its way back to Earth.
Once the fight was over, the Cult Leader would kneel dying in front of Isaac and Carver. The player(s) could kill him with a single shot or leave him be and proceed with the mission.
Choosing either to kill or spare him rewarded the players with two mutually exclusive achievements/trophies, "Heretic" if the Cult Leader was to be killed and "True Believer" for the opposite.
- In Dead Space Martyr, it was hypothesised that the Markers only show visions of dead people, yet the prophet is clearly alive, in person, in a vision. A plausible explanation is that the Brethren Moons, in tandem with the prophet's assault, have somehow "boosted" the magnitude of Isaac and Carver's dementia, thus giving them a devastating mental disadvantage over the sole attacker. The Cult Leader was able to seemingly use Isaac's and Carver's dementia to his advantage by dodging their attacks and stunning them with Stasis.
- In the IGN.com developer commentary interview, when Isaac approaches the scene of the cult leader standing over a kneeling man, IGN commentator Casey Lynch asks "is that indeed Randall Carr right there?" to which Producer Shereif Fattouh says yes. This has caused many to mistakenly believe that Randall Carr was the cult leader. However, text logs throughout the ship suggest that Carr was not the cult leader but the man kneeling before him.
- As the prophet, he acts in a very similar manner to Pyramid Head from the Konami game series Silent Hill. First, he is a fairly slow and lumbering enemy that uses a large knife. Second, he cannot be killed (though will react to the player's attempts to harm him) and cannot be slowed down further until his final boss fight, making his encounters more about avoiding him outright and running than attempting to fight back. Lastly, he seems to be the product of the player's inner demons and dementia, especially when hallucinations become part of his fighting style.
- It seems the first step of joining the Cult is to saw off one's hand, yet the Cult Leader seems to be the only member who still had both of his hands intact. This is most likely in order to perform the physical task of sawing every newcomer's hands off.
- Although his behavior during battles was similar to Nicole's at the end of Dead Space 2, making physical contact with the Cult Leader would not result in the player's death as it did with her. Just like the hallucination of Nicole, The Cult leader also will taunt Isaac and Carver by making sinister laughs.
- Despite having no official name in the DLC, the Brethren Moons refer to the cult leader as "the prophet" (a person who speaks for God or a deity), in this case, the Brethren Moons themselves.
- If Isaac or Carver was finished off by the prophet's attack (Usually with his blade), the Cult Leader would saw through Isaac (Or Carver's) neck violently. While Isaac's or Carver's neck was sawed through, almost to the point of falling off, the prophet threw Isaac's or Carver's body aside, tearing their heads off in the process.
