The Screamer

Unlike common Ex-Pop, the Screamer does not actively patrol the Trial Environments to kill Reagents. Instead, he involuntarily sleeps at random points during each Trial, either lying on the floor or standing still in a limp, semi-vegetative state while snoring. If Reagents wake him up by making too much noise while he is nearby or makes physical contact, the Screamer, true to his name, shrieks hysterically into his voice amplifier. Any Reagent that gets caught in the Screamer's sound radius experiences a disorientating fuzz in their vision and will cause them to clutch the side of their head, interrupting any action they were doing, along with hearing impairment and greatly reduced movement speed for several seconds. Additionally, his scream can also attract nearby Ex-Pop to their location. The Screamer then runs away from his spot in pain and fear to find a new location to sleep in, restarting his behavior.

Screamers are the result of research done by Nazi scientists during the Second World War. Screamers are produced by exposure to the Morphogenic Engine while screaming causing mutations to their vocal cords. Unlike most other Ex-Pop, the Screamers are not of Murkoff's creation at all but instead are the product of Operation Paperclip scientists who describe the Screamers as "always sleeping and never sleeping." Essentially, the Screamers are in a constant near vegetative state that resembles sleep when in actuality they are awake and aware of their surroundings. The Screamer is reclusive, skittish, and fearful. Unlike most of the other Ex-Pop, the Screamer shows no interest in harming the Reagents. Instead, he prefers to keep his distance from them, making him one of the only Ex-Pop to be fearful of the Reagents, rather than wanting to kill them.

Like many of the other Ex-Pop in the Trials who have been heavily tortured and experimented on, the Screamer's body is covered in rashes, cuts, and gashes. Some parts of his body are covered in tape or bandages. He is naked except for his high-waisted underpants. Additionally, there is a speaker device implanted on his chest, which is connected to the electronics in his mouth which resembles an oxygen mask. The wiring for the speaker device and oxygen mask have been inserted into a small scar slashed into the center of the Screamer's neck, presumably for further amplification of the Screamer's and additional modifications to his vocal chords. The Screamer's face is obscured by bandages over his right eye leaving him dependent on only his left eye to see. To protect the Screamer from his power, Murkoff has drilled protective headphones over his ears. When not woken up, he can be found sleeping in random places with his body twitching now and then.
