Before we go any further, it should be noted that there will *Major Spoilers* for the Dead Space Remake, primarily about Doctor Challus Mercer.

Who Is Challus Mercer in Dead Space Remake? Answered

Mercer is a scientist at the USG Ishimura and a member of the Church of Unitology, a cult-like group that believes that alien anatomy is the key to humanity’s evolution and salvation. Like the original Dead Space, Challus is one of the main antagonists who consistently tries to stop Isaac Clarke by prohibiting him from entering certain areas and unleashing his monstrous creations, such as the Hunter.

Based on record logs and interactions throughout the storyline, Doctor Challus Mercer has little regard for humans, especially with his brutal experiments on multiple individuals aboard the Ishimura. Yet, on the other hand, he is fascinated with the Necromoprhs, corpses mutated from the sinister object known as the “Marker.”

Why Is Mercer Sabotaging the Ishimura in Dead Space Remake?

Once Mercer witnessed the relatively invincible strength of the Necromorphs in the Dead Space Remake, he became obsessed with them. He wanted to enhance their abilities by performing tests on crew members, ultimately multiplying their numbers even more. As a result, those who were infected by the Marker and experimented on by the doctor would savagely sabotage the ship.

Challus didn’t care about the casualties or the state of the Ishimura; he only wanted to fulfill his mission as Unitologist. You can also consider how the Marker’s harmful effects made him go insane, along with signs of dementia.

Why Does Mercer Want to Trigger a Convergence in Dead Space Remake?

In the eyes of the Church of Unitology, the Convergence event is the final step to humanity’s evolution that will make them whole. Therefore, since Mercer is a dedicated believer in this cause, he will do anything to trigger this catastrophic occurrence, despite the eradication of humanity. To him, the Necromorph transformation is the beginning, and the Convergence will finally give the people the salvation he is seeking.
