Fritz & Jeremy (Emesis Blu)

Jeremy was the Scout for Builder's League United (BLU). He is first introduced when he shows up to Fritz's office for a check-up. Jeremy tells Fritz he has been having nightmares recently and feels as though he's being watched. Fritz assures Jeremy that he's just being paranoid and gives him a bottle of Valium to take. Jeremy is a kind hearted young man who has no malice in him at all. But he is shown to be willing steal from others, as he did take a VHS tape from Fritz Ludwig. Jeremy has an incredibly keen sense of balance, as well as relatively soft skin that moves smoothly. Both of his eyes are bright blue. He often wears his classic baseball cap, paired with a blue tee-shirt and denim-colored pants. He has a black bag strapped to his back, the dark gray strap goes over his tee, wrapping from his shoulder to his waist. He wears crew socks under comfortable sneakers. He wears yellow headphones with a mic attached underneath his hat.

Jeremy worked for BLU until he was laid off. Halloween night of 1968 he went to visit his friend Doctor Fritz Ludwig asking him if he ever had bad dreams.

-The Undertaker is one of the two overarching antagonists (alongside Jules Archibald) of the 2023 YouTube psychological horror movie, Emesis Blue.

He is an enigmatic figure appearing as a former Medic submerged in shadows and donning a plague doctor mask, now associated with the Conagher Brothers and their team of mutated, renegade mercenaries. Despite not having a major physical role, he is responsible for luring all of the main protagonists into the Slaughterhouse, where they would learn the truth about the Gravel Wars conflict and the nature of the Respawn Machine.

He also frequently appears as a visual hallucination to Dr. Fritz Ludwig and is an apparent representation of the darker parts of his personality, which could potentially mean that these two are one and the same.

In the film, he's first seen in one of Fritz's nightmares, where the latter experiences brief glimpses into the future and culminates with the Undertaker reaching his hand out to him in his own office. Fritz is awakened by Jeremy before the nightmare continued however.

The Undertaker also serves as the hand-off for the briefcase Stalingrad was commanded to send to the Slaughterhouse. When he dies at the hands of Jacques Murnau's personal assistant, Jane Doe, Jane is ordered to go back to his boss's car to get the camera so they could get at least get a picture of the body. It is then when the Undertaker attacks, pointing a gun to Jacques's face as a distraction to pick up the Intel and leave the area. Jane, however, takes a picture of him driving off in his black hearse.

It's implied that he also took a major role in the death of Jeremy's mother and her son's kidnapping, whistling the tune of "In the Hall of the Mountain King", a feat that would be impossible for the Butcher to accomplish given their burnt vocal chords. He might also be the one to hold her severed head to further scare Scout.

In a later hallucination, Fritz sees a disfigured version of himself committing the murder; and later in the film, he mimics the severed head trick, which could confirm he took a role in it.

One of the most popular theories regarding the Undertaker is his relation with Fritz Ludwig, most specifically, how they could be one and the same.

There are several clues, ones more explicit than others, that support this theory.

For starters, the movie has made it clear that, whenever Fritz is subconscious, he can go on murderous rampages described as him looking like he was in drugs and becoming strong enough to be able to stab a police officer with his own sidegun. Fritz also seems to actively fight off and even communicate to this "split-personality" of his through the mirror, with him hallucinating the split personality physically retaliating by coming out of the mirror. Jane and Cyclops even describe him as a "sleeper agent" for the Conaghers when they initially distrusted him.

He's also seen playing chess with Dr. Ludwig in Soldier's flashback. Chess was earlier portrayed as a reference to the BLUs and the Conagher Mercenaries, which signifies that Ludwig is literally playing for both sides and trying to outsmart and win against himself. Not only does this portray how he's a key element in both storylines, but also his inner conflict.

The Undertaker can also briefly be seen in one of Ludwig's visions, sitting in a funeral, with Ludwig in the casket, which implies that this is his funeral. This vision later comes true in the final chapter of Emesis Blue, Blood Brothers, where Ludwig hides in Jules Archibald's casket to surprise-kill Jacques. It is also in this chapter where Ludwig fully embraces his darker, murderous side, and goes on a murderous rampage before escaping town. This could be interpreted as Ludwig's personality dying (with his physical body dying shortly after).

Fritz Ludwig was a Medic working for BLU during the Gravel Wars. He first approached by his friend Jeremy who asks if he can be given a checkup because he had a dream that all his teeth fell out. Fritz resembles the BLU Medic in every way when alive, but after respawning in Jules Archibald's coffin he is gaunt, under weight and pale. Unlike his inspiration, Fritz Ludwig is more serious and sane and is seemingly more qualified to work as a medical professional. Before his second resurrection, he is a kind and companionate man who does what he can to help others. After his second resurrection however, he becomes a mute killing machine, with intent to finish Mann.co and leave with the briefcase. Seeming to still show an occasional trace of mercy or recognition, yet becoming much more hostile than his original self.

The Two-faced Medic is a minor antagonist in the 2023 YouTube psychological horror SFM movie, Emesis Blue. He was a RED Medic until he was resurrected as an undead. The Two-Faced Medic was the Medic who brought back Stalingrad from Death but was killed himself. Later he tried to kill Fritz Ludwig but Fritz Stunned him with a broken medigun. However Stalingrad broke into the room that Fritz was in and picked up the Two-faced Medic and crushed his skull. Before his Resurrection, he seemed like a normal Medic who was interested in playing god. After he respawns he acts more like a zombie, like The Jaunts. He has a RED Medic's outfit and as his name suggests, he has Two-faces. there is stitching in the middle of his face.
