Big Grunt

Following the horror of the trials created by Doctor Easterman, Reagents will meet deadly obstacles and challenges to gain freedom. In every program, Big Grunts will be deployed to hunt down every single person until none of them survive, thus failing the trial. They are tasked with a simple job, taking pride in every step of defending their home from the "commies".

Before Project LATHE phase one, it was unknown which facility they originated from. However, their facility is still connected with Los Alamos, possibly involved with Wernicke as well. They were subjected to growth hormone therapy and military-purpose limb-extension surgeries when they were in their early 20s. The experiments heavily injured and deformed their face, but at the same time, they were given extraordinary strength compared to other Ex-Pop. Unlike General Ex-Pop, they are more important for the project and taken care of with caution. Due to their abilities, they are conditioned through psychology more than physically, being compared to the "staked elephant". That being said, there are still limits to controlling their behavior, especially when it comes to violence and perversion of their actions. Heavy chemical and physical restraints are being used whenever Murkoff personnel need to maintain or transport them into another facility.

They have an extremely childish cognitive framework, believing in some fairy tales like Santa and Tooth Fairy, which is useful in their obedience conditioning. They often call their "Daddy" in their dialogues, possibly referring to Easterman, whenever they get hurt by the Reagents or are angry that they can't reach them. It was noted that Murkoff personnel need to be very careful maintaining their body, especially when it comes to the groin area - Big Grunts are easily aroused and difficult to disengage. Big Grunts are naïve, brutal, simple-minded, and sometimes flirtatious with the Reagents. They are also the most lustful compared to other Ex-Pop (except Coyle) and easily turned on. As they are the most dangerous and strongest Ex-Pop, Murkoff personnel are warned to avoid making them accidentally aroused.

They are conditioned to be obedient psychologically, as well as obsessed with making Dr. Easterman happy and satisfied. Some of the Big Grunts also take pride in their job hunting down the Reagents, confident that they are doing the job greatly and not wanting to let the scientist watch them struggle.

The brown-haired and naked Big Grunts have the similar personality; they are tough, proud of their job, and believe Murkoff is treating them fairly despite the scars on their body. They are also proven to be proud of their pain resilience and express no resentment towards Murkoff in comparison to the female Big grunts. One of the personalities speaks with a snarl while the other voice type speaks slowly in a deep tone with a notable southern drawl. The two female Big Grunts shared a similar personality while still differing from the male Big Grunts. They make less flirting remarks than the male large grunts, expressing their fear and disdain of Murkoff's treatment, but also having more playful personality than the male big grunts. For example, inviting the Reagents to play with them in order to coax them out of their hiding place. Aside from their larger size, they share the same torture-induced rashes and bloodied wounds, just as any other Ex-Pop, due to being subjected to the same twisted experiments from the Murkoff Corporation's experiments and abuse.

There are four Big Grunts known in the Sinyala Facility. Danny has shoulder-length brown hair, green eyes with one being scarred and cloudy, thick reddish lips, hairy arms and chest, as well as a beard. He has a chest brace wrapping around his body, with the pieces drilled into his ribs and backbones. He wears metal braces on his left arm and leg (similar to Nick Tremblay) with a medical tube filled with blood tied around. He has an abnormally large torso, with a bandage wrapped around his burnt left arm and right leg. He wears a pair of mismatched-length blue pants with two belts holding it.

Darrel has no hair, is completely naked and has blue eyes. He has several metallic poles emerging from his skull. He shares a similar body model and left arm surgery device with the brown-haired Big Grunt, although he is thinner, has a longer face shape, and a paler skin tone.

Lorraine has a black skin tone, 4C afro hair type, bandages wrapping around her face to cover her face scars and deformity, one eye is covered, with teeth showing as she has no lips. She is half naked wearing a ragged dress with her right breast showing, although sometimes she appears fully naked in the trial. She wears a right arm brace, with a heavily torn but still functioning left leg prosthetic. Her amputated leg also appears to be rotting with the flesh starting to fall apart beneath the prosthetic. She wears a brace on her chest wrapping her body around her back, similar to the brown-haired Big Grunt. Her left arm also appears to be bleeding and starting to rot, thus being wrapped with bandages.

Belle wears prosthetic face pieces, just like Gooseberry, however they are porcelain and only cover her lips and upper brow bone. She also has a noticeably large portion of her skull missing, causing her head to be indented. She is bald, with only a few strands of her hair left on her scalp. Wires, braces, and stitches decorate her pale white body in irregular places. She has a long stitch across her lower stomach and lacks one of her breasts, with her nipples being cut off completely. She has long sharp nails, and her hands are particularly bloody. Unlike other Big Grunts, she has a straight back thanks to the brace drilled from her backbones to her lower skull part. She is completely naked, with her lower hair covering her genitalia. Her eyes are reddening, with one nearly completely closed making her rely on her left eye.
