Description[]
Thomas Jefferson Wilson, popularly known by the sobriquet "The Party Pooper," is a human infected with the Sanguine Festivus Virus who has freed himself from the mind control imposed by the virus. The exact cause of how he resisted the control is uncertain. The Party Pooper plays the role of a vigilante, mainly combating the Partygoers and the forces of Caius Taggert, his archenemy. Due to the virus in his body and his resistance to its control, he uses his superhuman abilities as an infected to help, guide, and encourage the wanderers he encounters on his path.
There are numerous reports of The Party Pooper saving and helping various wanderers in several dangerous levels of the backrooms. He is mainly described as a kind and humble individual. The reports range from The Party Pooper saving people from groups or hordes of entities like Smilers, Dullers, Hounds, Aranea Membri, Skin-Stealers, and Partygoers, among countless others he fights and eliminates on his way, to peacefully approaching communities in need of supplies, offering them his resources and providing information about nearby larger bases. Most of these reports occur in survival class levels 3 to 5, with only one report of a Party Pooper sighting in a class Deadzone Level, Level -250, where he was seen saving a group of wanderers from a 50-meter Predatory Pylon, killing it while wielding his axe. He is also said to be tough; in certain cases, wanderers have reported that The Party Pooper can heal quickly from severe injuries and even the loss of limbs in battle, guiding wanderers despite his injuries with a certain resilience to pain.
However, The Party Pooper only gained notoriety during the cataclysmic events of The Flicker, where the lack of supplies and the increase in the number of hostile entities left many wanderers and communities powerless and succumbing. Thanks to The Party Pooper's actions, certain groups and wanderers managed to survive, with numerous groups persisting due to the supplies provided by The Party Pooper and many survivors being saved from prevalent hostile entities and guided to safe bases by The Party Pooper. These actions had a significant impact on most wanderers during this event, as Party Pooper showed that even in pure darkness, it was still possible to find a light. He indirectly influenced thousands, or perhaps millions, of people not to give up and to remain in the fight for survival.
The Party Pooper seems to have a certain link with the members of the Party Crashers, who see him as an icon and draw inspiration from him in their fight against the Sanguine Festivus. The Party Pooper is involved in the armed conflicts and constant battles against the Partygoers during the Euphoric Wars and The Second Crash where he appeared to act together with the group. However, due to a lack of information about this period, the only relevant information about this possible alliance and connection between the two is the common actions taken by The Party Pooper. Most wanderers infected with the Sanguine Festivus virus, who can still be cured, are usually guided by The Party Pooper to Party Crashers bases. He often offers supplies and weapons he finds during his journey to the group’s outposts and communities. The direct relationship between the two remains a mystery, but it is presumed that The Party Pooper might be a member of the Party Crashers or at least a significant ally.
Some time ago, The Party Pooper was thought to be multiple different individuals due to the majority of sightings being very close to one another. However, after further research and investigation, it was discovered that all the reports were about a single person, Party Pooper, who was very quick in his rescues and assists due to a unique property of the virus. Similar to the Partygoers, The Party Pooper is capable of performing a unique no-clip called "Induced Quantum Tunneling." The virus enables the infected to not only perform no-clips but also to control their destination, allowing for effective no-clipping between levels and even passing through solid objects with greater ease.
Appearance[]
Having been infected by the Sanguine Festivus virus, The Party Pooper has yellowed skin and a deformed face. However, he hides his true appearance by wearing clothes that cover his entire body, such as a gray hoodie, hood, long pants, and his iconic melancholic mask—a faded blue mask with a sad face representing an emotion opposite to that of the revelers. The Party Pooper revealed that he chose to adopt the sad face as a way to repudiate the essence of the virus and also to embody the emotion that most frightens the revelers: sadness. Signs of wear, such as some tears and stitches in his clothes, may also be seen.
The Party Pooper revealed that his mask was initially improvised and did not have the sad face. It only acquired this face after his old friends were cruelly murdered and devoured by a group of Partygoers. Since then, Thomas Jefferson Wilson adopted the name Party Pooper and began to repudiate the Partygoers and their grotesque blood-soaked parties, becoming the exterminator of these macabre festivities and hiding everything that made him look like one of the infected, including his skin and face.
Behavior[]
The Party Pooper is a mysterious and intriguing figure, characterized primarily by his altruistic actions and silent presence. Many say that, for some reason, they feel more confident in The Party Pooper than in their own allies, even though he often appears as a silent man of few words. The Party Pooper himself has mentioned that he feels this aura of trust seems to be some kind of effect of the virus, as the Partygoers also seem to possess the same aura. The main goal of the Party Pooper appears to be the complete destruction of Level Fun and the Partygoers, along with their leader Caius Taggert, so that no one else suffers what he suffered in the past.
The Party Pooper is described as a lonesome and silent man by the majority of the wanderers he saves. Most of the encounters he has with hostile things conclude before the wanderers have a chance to speak with him. But when the Partygoers are the entity he is interacting with, his actions alter. The Party Pooper revealed that because he is infected, he is able to sense the presence of the Partygoers in the same way that they do. This keeps him from striking without warning because the virus sometimes allows the infected to evade or counterattack.
In situations where The Party Pooper is heavily outnumbered, usually when surrounded by Partygoers or near a Level Fun entrance, if he finds himself only near groups of Partygoers, he will opt to leave unnoticed. However, in ambush situations, he will choose to protect the wanderers he is with, prioritizing their safety and, based on the actions of the Partygoers, counterattack effectively. This is due to the Partygoers' tendency to hunt and attack the weakest people first, which allows The Party Pooper to predict their movements and use this to eliminate them effectively.
When there are only a few Partygoers or just one nearby, he will opt to deceive it in order to attack it unexpectedly. He will start with common conversations among the infected, trying to gain the Partygoer's trust. Thanks to the virus in The Party Pooper's body, the Partygoer may end up believing he is an ally. However, in situations where the Partygoer realizes he is an enemy, it will aggressively attack The Party Pooper, who responds quickly by decapitating it with his axe. Normally, The Party Pooper chooses to deceive them so that they cannot attract the attention of other Partygoers through the virus.
Weapons:[]
The Party Pooper is consistently observed wielding an axe, which, according to him, is a mystical, blessed object that chose him during the events of The Second Crash and saved him from a direct ambush by Caius Taggert. The Party Pooper named the weapon the “Glorious Axe”, claiming to perceive a radiant, glorious aura emanating from it.
The axe’s primary ability is the capacity to cut through any surface—solid or non-solid—extending even to the air itself. This cutting ability prevents the affected material from recombining or restoring its original form. Even when applied to liquid substances, the separated portions are unable to merge again. This property enables the Party Pooper to inflict fatal damage on entities with advanced regenerative properties, as such entities are destroyed instantly, disintegrating or evaporating upon being struck.
Based on a series of diverse experimental assessments, it has been demonstrated that the Glorious Axe is not only capable of penetrating any surface but also possesses the ability to “erase” any biological entity struck by it. When the axe severs part of a living organism, the affected area disintegrates entirely, preventing any form of reconnection or regeneration, regardless of its biological or metaphysical nature.
This phenomenon is observed in combat scenarios involving the Party Pooper and the Partygoers. Unlike the Party Crashers, who incapacitate Partygoers for extended periods using Fire Salt—reducing them to skeletal remains from which they eventually regenerate—the Party Pooper’s use of the axe results in permanent termination. Decapitation by the Glorious Axe completely severs the metaphysical connection that sustains the Partygoers’ life functions, effectively “shutting down” the mechanism that allows them to persist without a head.
Evidence suggests that this property operates through the erasure of non-conscious components of the targeted organism. When the axe severs a limb, the removed section is annihilated at an unidentifiable, submolecular level, leaving no detectable residue. This hypothesis is further supported by the observation that total disintegration occurs exclusively during decapitation. The prevailing theory proposes that both the head and the body are rendered “non-conscious” immediately upon sudden death, causing the complete erasure of both components from existence.
The axe is also indestructible. Tests authorized by the Party Pooper were conducted to attempt its destruction, but all efforts failed. Experiments including disintegration, crushing, compression, and corruption attempts demonstrated the weapon’s exceptional resilience. Furthermore, the axe can only be moved or lifted by the Party Pooper himself. Experimental attempts to weigh the weapon resulted in either implausible readings or mechanical failure of the scales.
Another documented ability of the axe—referred to as its “glorious aura” due to its mystical nature—is the seemingly anomalous capacity for the Party Pooper to survive catastrophic or inescapable events. Based on certain studies, this aura has been hypothesized to act as a localized probabilistic distortion field, wherein the surrounding area is spontaneously reorganized to ensure Party Pooper’s survival, typically through random accidents or unforeseen occurrences.
Interview[]
The interview took place during a meeting between a group from M.E.G and Thomas Jefferson Wilson (The Party Pooper) at Level 52. The group quickly asked if they could conduct an interview with him, and Party Pooper accepted.
<start audio transcription>
Dr. Ekaterina (Interviewer): Hello Mr. Thomas Jefferson Wilson, or should I call you Party Pooper? We are grateful that you accepted our interview.
Thomas Jefferson Wilson (Interviewee): At your service. By the way, you can call me Jeff. I think it's simpler and easier to refer to me that way.
Dr. Ekaterina: What did you do before you fell into the Backrooms?
Thomas Jefferson Wilson: Let's say I was just a rebellious teenager who enjoyed graffiti and skateboarding. Nothing more, not a very sociable person, nor someone who stood out in anything—just a simple and normal teenager.
Dr. Ekaterina: What led you to contract the Sanguine Festivus Virus?
Thomas Jefferson Wilson: Well, the year was 1968. I was very young at the time, around 17 or 18 years old. I had a group of friends called "The Comrades." We lived in the Marshall David Campus on Level 52. I was very innocent, always wanting to help everyone I met along the way. And then we encountered a poor man asking for supplies and a safe place to spend the night. My friends were suspicious, but I naively accepted. That's when the man revealed himself as a disguised Partygoer and attacked me and my friends. Not knowing what to do, I quickly tried to defend my friends using a baseball bat as an improvised weapon. I even managed to scare off the Partygoer, but he had seriously injured me. The friends I tried to protect showed indifference and closed the door on me. I was isolated, abandoned, and rejected. I fled to another room on the campus, where I faced death alone. But by luck—or perhaps misfortune—the Partygoer's bite infected me with the Sanguine Festivus Virus, and I managed to survive.
Dr. Ekaterina: I understand, truly a sad story. Could you tell us what made you become the famous Party Pooper and start practicing altruistic acts?
Thomas Jefferson Wilson: Well, following the events I described, after contracting the virus, I noticed the yellowish hue of my skin and, upon seeing my reflection in a nearby window, I saw a horrible sight—my deformed face. I swear I cried a lot at that moment, but I didn't let it shake me. I wanted to apologize for letting the Partygoer into the base, so I gathered some items I found in the campus rooms and created a makeshift costume and mask. Initially, the mask didn't have the melancholy symbol. Then I set off to reconcile with my friends. When I returned to the base, I saw the most traumatizing scene of my life—a group of about six to seven Partygoers voraciously devouring my friends. One of them turned to me; it was the same one who had deceived us. He then uttered the following words, "Hey you there, looks like you've also been blessed by the liberation of the virus. Join our fun party, brother." I was paralyzed, not knowing what to do. Consumed by growing fury, I charged at all those damned creatures, annihilating them one by one with my bare hands...
Dr. Ekaterina: Wow.
Thomas Jefferson Wilson: It was on that day, July 8, 1968... on that exact day that I completely repudiated this virus... those damned Partygoers... and once and for all... I began to call myself "Party Pooper," a symbol for the end of all the bloody parties thrown by these monsters. I became their opposite. I drew a sad mouth on my mask to be their antithesis and to spoil all their carnages they call parties.
Dr. Ekaterina: You mentioned being 18 years old in 1968 but you don't look old at all, could this be an effect of the virus on your body?
Thomas Jefferson Wilson: As incredible as it may seem, I may be old in age, but I literally feel like I'm in my prime.
Dr. Ekaterina: I see... Could you explain how you found your typical axe?
Thomas Jefferson Wilson: I feel like the axe found me... as if I was chosen by it... but I think that would be too long a story to tell in this interview.
Dr. Ekaterina: In some reports, it is said that you tend to use firearms instead of your axe. Could you explain the reasons behind these decisions?
Thomas Jefferson Wilson: I kind of only use my axe when I think it's necessary to use it. I also only use it when dealing with entities that can regenerate quickly or can dodge bullets. An example would be the Partygoers who, in addition to their regeneration thanks to the virus, can dodge bullets.
Dr. Ekaterina: What is your relationship with the Party Crashers?
Thomas Jefferson Wilson: I would say I'm a great ally of theirs. After proclaiming myself Party Pooper, I helped them in The Great Crash that took place on Level 52.
Dr. Ekaterina: What is your relationship with Caius Taggert, the leader of the Partygoers?
Thomas Jefferson Wilson: I swear that someday I will kill that bastard who commands these monsters. But even after many attempts, he remains undefeated, immensely stronger than I am... not even my axe can cause him significant damage. That guy is more than a monster, and even if it takes me decades, someday I will manage to end him and his cursed parties.
Dr. Ekaterina: There are reports of people seeing you entering Level Fun. Are these reports true?
Thomas Jefferson Wilson: Yes, almost all reports about me are true. Well, I often go to Level Fun, sometimes consciously, sometimes unconsciously. Some days I go just to eliminate all the Partygoers near the entrances. Level Fun tends to create deliberate entrances on certain levels where there are Partygoers. But sometimes, just being near an entrance, I feel an uncontrollable urge to enter. And I say more: Level Fun is undoubtedly the most terrifyingly welcoming level I've ever been to. I think it must stem from a property of the level, but when I enter it, I feel safe and welcomed in a way that even scares me. The rooms and corridors are also highly confusing and illogical, as if the level has a non-Euclidean logic, which makes the exit more difficult, as the only exit doors are the entrance doors themselves...
Dr. Ekaterina: Indeed, due to the numerous dangers cited, it is difficult even for M.E.G. members to conduct in-depth research on Level Fun. Many members of the Party Crashers seem to possess deep information about Level Fun. Are you an informant for them?
Thomas Jefferson Wilson: I wouldn't say informant, but yes, I do provide information about the level to the Party Crashers, and I have helped them enter the level safely. But that's because they are my allies in the fight against Caius Taggert.
Dr. Ekaterina: Good information. Thank you very much for coming, Mr. Jeff, and thank you for the information provided. We hope to see you on more days like this.
Thomas Jefferson Wilson: At your service. Now I'll head off on another expedition to Level Fun to prevent more Partygoers from spreading among the levels.
