Friday Night Funkin': Corruptionnote  is a web series/Game Mod of Friday Night Funkin' created by Phantom Fear. Told primarily as a series of sprite-swaps for the original game, it is one of the first Dark Fics to make rounds in the game's community.

Set in an alternate timeline that begins with a different ending to Week 5, rather than personally deal with Boyfriend and Girlfriend, Monster decides to aim higher by unleashing the titular corruption on the world. Taking the form of a black-and-pink tar-like substance that envelops the target before giving them claws and a Nightmare Face, Boyfriend and Girlfriend are first to be turned into monsters with the sole purpose of spreading the corruption even further.

With Monster's primordial evil rapidly spreading, the other characters are now forced to fight for their lives in a very real struggle against the once-pure duo - and while it may be possible to save them with The Power of Rock, it slowly becomes horribly apparent that the cost may be immense.

The playlist for the entire series can be found here. The mod is still being worked on, but a demo of Week 2 is currently available through this video, and a playable Week 6 is available here.

There is also a short, non-canonical animation made for Christmas 2021. A canonical animation called "Corruption" that serves as the opening for Week 8 and beyond in this mod was created in September 30, 2023.

Friday Night Funkin': Corruption contains examples of:

    Tropes A-H 
  • Adaptational Badass: In the original game, Daddy Dearest is the first enemy faced with some of the easiest songs; in Corruption, he is the final uncorrupted enemy faced with some of the hardest songs in the entire mod.
  • Adaptational Heroism:
    • Pico, the mercenary who was hired to kill Boyfriend in the original game, got corrupted trying to save him from his corruption.
    • Mommy Mearest, an Ax-Crazy lady who tried to kill Boyfriend, is pulling out all the stops to try save Pico during their Week.
    • Senpai's hardcoded desire to win is depicted as a savior complex instead of a Bitch in Sheep's Clothing persona; after realizing something's wrong, he holds the line thinking he can protect Girlfriend from Boyfriend, but becomes visibly forlorn once he realizes they're fighting together. Even after losing to Boyfriend a second time, he simply demands they exit the game and leave him alone, only fighting back once Boyfriend attempts to delete him.
    • Daddy Dearest, who was very adamant at keeping his daughter away from Boyfriend, now tries to stop him once and for all.
  • Adaptational Intelligence: Downplayed: while Boyfriend and Girlfriend are still Fearless Fools, the two take the situation at hand seriously and put actual thought into how to defeat Nexus Pico in Week 10, with Girlfriend theorizing that striking Pico will free him and Boyfriend distracting him to do so.
  • Adaptational Late Appearance: Daddy Dearest in Friday Night Funkin' was the first boss for Boyfriend to ever face in a genuine rap battle. For the Corruption mod, Daddy Dearest appears in Week 7, being the last surviving victim to be confronted by the Corruption.
  • Adaptational Location Change:
    • Week 4 in the original Friday Night Funkin' took place on a highway at sunset, while Week 4 in the mod takes place in an unknown, foggy area. Justified, as Corruption Week 4 takes place after the canon Week 4.
    • As for Week 11, the circumstances that lead to fighting Tankman take place on a highway rather than the desert like in the original game. Once Boyfriend successfully frees Pico from the Corruption, an army of Tankmen rush in to fight them.
  • Adaptational Seriousness:
    • In the original game, Skid and Pump are opponents that Boyfriend and Girlfriend rap in a spooky mansion just for fun, but the Corruption mod instead has Skid be forced in a dangerous situation where he has to rap against the corrupted victims.
    • The canon counterpart of Daddy Dearest is a Smug Smiler Jerkass that wants to stop Boyfriend from dating his daughter and tries many repeated attempts to stop him through overcomplicated schemes. In here, Daddy Dearest is a Perpetual Frowner that has crossed the Despair Event Horizon and is a much more difficult boss that directly faces down Evil Boyfriend and the horde of corrupted victims.
  • Adaptational Sympathy:
    • Canonically, Girlfriend's parents are bastards who only care about themselves and their daughter. While still true within the mod, Corruption forces them to deal with the consequences of their actions in the most horrific way possible, losing everything in the process. In particular, Daddy Dearest is genuinely distraught over how hellish the situation is, trying everything to stop Boyfriend, and is so devastated over his wife's corruption he rapidly corrupts after being forced to fight her.
    • Within Friday Night Funkin', Senpai is a vulgar Sore Loser and Spirit, while understandable, is still trying to steal the body of an innocent person. In Corruption, Senpai's fear and Spirit's anger over the situation are highlighted as Boyfriend destroys the game from the inside out and neither of them can do anything to stop it.
  • Adaptational Villainy:
    • Monster, while a Soft-Spoken Sadist who had a fascination with eating Boyfriend and Girlfriend, that was pretty much all he was. Here, he lets loose a virus with the potential to take everyone's free will.
    • Due to being the first ones corrupted, Boyfriend and Girlfriend fight to spread the corruption rather than prevent it. Subverted later when they get uncorrupted and immediately start trying to reverse the damage they caused while corrupted.
  • Adapted Out: Due to Corruption branching off during Week 5 and Tankman not being in the base game at the time, the canon Week 7 never happens, with Tankman getting corrupted off screen. While Boyfriend and Pico ultimately fight corrupted tankmen during Weeks 10 and 11, the circumstances are entirely different, and Tankman himself still doesn't make an appearance.
  • A God Am I: Many of the Tank Amalgam's lines come from the book of Revelation from the bible and they are used to reinforce his status as a high-ranking deity. By declaring himself as the Alpha and the Omega, Tankman is claiming himself as God, since those are one of the titles the latter is called. Furthermore, Tankman claims himself to own the keys of Hell and death.
  • A Handful for an Eye: Boyfriend uses his Impaled Hand to splash blood onto Evil Pico's face, giving time for him to punch the distracted Pico.
  • Alien Blood: If the bleeding wounds in Skid and Pico's sprites are any indication, Corruption shells bleed out pink blood.
  • All There in the Manual: The description for the "Evil Pico vs BF Final Battle" video explains the form Corrupted Pico takes during "Blood Moon", along with its name, Nexus.
  • Allegiance Affirmation: When initially introduced in Week 8's first song, "Tormentor", Soul Boyfriend is set up as the manifestation of The Corruption that's taken control of Boyfriend's body. "Neuroses" throws that into question, as Soul Boyfriend reminds Boyfriend to stay focused when he falters and that the corruption "isn't my doing". "Discharge" firmly establishes Soul Boyfriend as a distinct entity with Boyfriend's best interests in mind; performing a Dynamic Entry and tossing him a guitar, Soul BF pulls Boyfriend out of his funk and the two play one final duet, ultimately breaking him free from the corruption's control.
  • All for Nothing: The Freeze-Frame Bonus of Week 8 suggests that all of the corrupted individuals are technically dead, with the corruption propping up their bodies and minds. If true, this would render the entire week pointless, as their wouldn't be anyone to save even if Boyfriend broke free. The ending of Week 9 reveals that this was a lie, with Girlfriend being restored to her former self after Boyfriend defeats her.
  • Always a Bigger Fish: The Tank Amalgam is a huge threat that requires Boyfriend and Pico to work together to stand a chance against him. Despite their rapping and shooting, the duo are unable to dent Tankman by one bit, and the latter is only defeated by the Harvester intervening in the end of "Hivemind". Whether the Harvester is evil or not, they are still proven to be strong enough to overpower the Tankman that had worried Boyfriend, Girlfriend, and Pico.
  • Ambiguously Evil:
    • In Week 8, as the original Boyfriend gains the upper hand during "Neuroses", Soul Boyfriend says things like "Not again", "This isn't my doing" and "Focus on our battle", implying he may not be the true face of the Corruption and has been subjugated before. Ultimately, "Discharge" confirms that he's been benevolent from the start, as he helps Boyfriend break free of the Corruption. Soul himself lampshades his initial, seemingly evil status near the start of "MEMORY//LEAK".
    Soul Boyfriend: So much for making me the "bad guy".
    • In Week 11, an Original Character called the Harvester makes their official debut by watching over Boyfriend, Pico, and Girlfriend fight the Tank Amalgam. Near the end of Week 11's song, "Hivemind", the Harvester takes action by killing off the Tank Amalgam and extracting his souls from the deceased soldiers. Whether the Harvester is looking out for themselves or is assisting the protagonists is left unknown.
  • Ambiguous Situation:
    • It's left intentionally unclear how much of a victim's original self is sealed away while fully corrupted, likely as part of the indication that the corruption isn't incurable.
    • While trying to convince Boyfriend to give in, split second dialogue by the corruption in "Discharge" suggests corrupted individuals may not even be alive in the traditional sense anymore, but it's left unclear if it's telling the truth or not. The ending of Week 9 reveals it was all Corruption's bluffing, as Girlfriend is alive and well after being uncorrupted.
  • Anachronic Order: From the core game's perspective, the game's chronology goes from Week 5 to Week 3, then to Week 2, then to Week 4 and Week 6 simultaneously, then finally to Week 1, which is renamed Week 7.
  • And Then John Was a Zombie: For the surviving characters that tried to fight off the Corruption in the first five weeks, they all lose and succumb to The Virus with whatever resistance they tried being All for Nothing.
  • Animesque: The game gets its own anime-styled opening song, and the Harvester is voiced in full Japanese.
  • Anthropomorphic Personification: It is implied that Soul Boyfriend is the personification of Boyfriend's reckless courage and will to keep going, created by his mind in an effort to rouse him and break free from the corruption's control. Even after Boyfriend leaves his mind, Soul Boyfriend is still there to support and encourage him.
  • Anti-Frustration Features:
    • The two Difficulty Levels mentioned below are present to allow the player to ease their experience if need be.
    • Any weeks that are not implemented yet, but are still classed as finished are dubbed as "Watchable", and the difficulty option is changed to picking which part of that week you wish to view on YouTube. Likewise, any that are implemented are classed as "Playable".
    • During "Hivemind", control will switch at times to one of the duo of Boyfriend and Pico, and if they're both going at it in unison, the character you're not controlling in that moment will have their Botplay toggled on automatically to save you some extra notes.
  • Anti-Regeneration: "Estranged" has Evil Girlfriend drive Boyfriend into his insanity in order to corrupt him and Boyfriend's inability to focus on battling Girlfriend is represented by his health draining.
  • The Apocalypse Brings Out the Best in People: All of the game's rivals set aside their previous agendas to fight back the encroaching corruption.
  • Arc Villain: Although Evil Boyfriend is the villain with the most screen time in his goal to corrupt the characters, other corrupted characters get to have their own spotlight to corrupt their own victims.
    • Evil Pico is the Arc Villain for Week 4, as he meets Mommy Mearest and rap battles to corrupt her. After Evil Pico corrupts her, he is never seen again until "Deathmatch", where is he one of the corrupted victims that go against Daddy Dearest.
    • Before becoming the main villain of her own week, Evil Girlfriend only bops her head around as Evil Boyfriend corrupts his enemies. In Week 9, Evil Girlfriend takes the lead as the villain for Boyfriend to save from the Corruption. When Girlfriend is broken free out of her Corruption, she reunites with Boyfriend and assists him in fighting Evil Pico for Week 10.
    • Evil Pico returns again as an Arc Villain for Week 10, since he attempted to kill Girlfriend and Boyfriend in Daddy Dearest's stage. Evil Pico starts his week by standing Atop a Mountain of Corpses, before blowing it up to increases the intensity of his battle with Boyfriend. Upon being pushed into a corner, Evil Pico goes Nexus to gain better fighting abilities in killing Boyfriend, but ends up losing in the end.
  • Art Evolution: The story initially starts out as a basic sprite-swap that completely fills in Boyfriend and Girlfriend's sprites with solid black and simply adds in the face of the human head from "Winter Horrorland"; as the series progresses, more effort is put into adding extra details to the corrupted characters to make them stand out, in addition to the backgrounds going from edits of the original scenes to whole sale new ones. This is best showcased in "Allure", where the song begins with Girlfriend's original sprites before fading to reveal a new, more detailed design.
    • Phantom Fear has stated himself that the new designs introduced in the "Saving" portion of the mod will be ported over to the original "Evil" weeks for the mod's eventual release, possibly hinting at Evil Boyfriend himself getting a new design of his own.
  • Attack of the 50-Foot Whatever: Tank Amalgam, for more go see Always a Bigger Fish and Big Bad Wannabe.
  • Atop a Mountain of Corpses: Throughout the entirety of "Extractor", Evil Pico stands on the top of Tankmen corpses as he battles Boyfriend and Boyfriend. As "Extractor" nears its end, Evil Pico pulls out a grenade to blow up the corpses and raps Boyfriend more intensely.
  • Autobots, Rock Out!: "Discharge", the second to last song of Week 8, is an intense, high-energy rock track with heavy electric guitar that sets the stage for Boyfriend finally breaking free from the corruption. Humorously, the trope is Invoked by Soul Boyfriend, who throws Boyfriend an electric guitar and tells him to play; the song is mainly a duet between the two of them.
  • Back from the Dead: The dead Tankmen who had their bodies mutilated come back to life through the power of the Corruption and the undead army approach Girlfriend, Pico, and Boyfriend as a horde of zombies in "Brainstorm".
  • Back for the Finale: The fauxnale "Deathmatch" has Daddy Dearest face off against not only Boyfriend, but all of the corrupted characters save for Girlfriend, Senpai, and Spirit.
  • Badass Armfold: In Week 8, Soul Boyfriend's left pose has him confidently cross his arms.
  • The Bad Guy Wins: Each Week ends with the opponent being overwhelmed by the corruption, and Week 7's final video ends with Corrupted Boyfriend successfully corrupting Daddy Dearest, with the corruption soon after spreading to the rest of the world. Subverted with Week 8, which sees Boyfriend brake free from the corruption's grip.
  • Bad Moon Rising: Throughout "Extractor" and "Headshot", the moon slowly rises during both of the songs. In "Blood Moon" however, the moon glows once Evil Pico transforms into his Nexus form, signifying the battle becoming more dangerous for Boyfriend, later in "Hivemind" it glows again but with a reddish effect, possibly to represent Tank Amalgam's large threat towards BF and Pico.
  • Baritone of Strength:
    • Unlike in "Lament" and "Dusk", Daddy Dearest sings in a lower register during "Deathmatch" as he's fighting off Boyfriend.
    • In Boyfriend's mind during Week 8, Soul Boyfriend has a noticeably deeper voice than normal BF.
  • Battle Aura: During "Discharge", Boyfriend manifests an ominous purple aura as the Corruption tries to threaten him into giving up. Soul Boyfriend responds with his own brilliant white aura.
  • Battle in the Center of the Mind: Week 8 has Boyfriend, deep inside his mind, fighting against the corruption inside his body to free himself once and for all.
  • Beat the Curse Out of Him: During "Blood Moon", Girlfriend suggests to Boyfriend that tiring out Pico and then attacking him directly could free him from the Corruption. She's right: a punch to the face causes the Corruption to splinter and break off like a shell, returning Pico to normal.
  • Being Watched: "Neuroses" has Soul Boyfriend advise Boyfriend to not focus on the fact that Evil Boyfriend has spotted them and looking directly through the static screen. Evil Boyfriend staring at Soul Boyfriend and Boyfriend's eventually results in the latter falling into a Heroic BSoD from the lack of confidence.
  • Better to Die than Be Killed: It is heavily implied Pico shot himself so the corruption couldn't use his body. Unfortunately for him, he lived.
  • Beware the Nice Ones: Senpai presents himself as a Nice Guy and Chick Magnet, but when presented with a pair that threaten both himself and the game he's in, he drops all pretense and hits Boyfriend with everything he has, which is quite a lot.
  • Beware the Silly Ones: Monster, while still a Laughably Evil lemon-headed Humanoid Abomination with a fascination with eating people, still managed to spread the titular corruption to most of the main characters of the original game via Boyfriend and Girlfriend.
  • Big Bad Wannabe: The threat the Tankman Amalgam poses to the protagonists is so great, that no matter what attacks are thrown, nothing seems to be affecting Tankman. Although Tankman is a formidable threat that might have beaten Boyfriend, Pico, and Girlfriend, he fails to compare to the powers of the Harvester. Once the Harvester steps into the battle from afar, Tankman is immediately defeated via explosion.
  • Bitch in Sheep's Clothing: In an act to fool Boyfriend that he won, Evil Girlfriend pretends to have been saved by him via illusion. In that illusion, Evil Girlfriend pretends to be grateful from having been "saved" of the Corruption, but as she lures Boyfriend to get closer, she reveals her true nature in an attempt to stab him by her black tentacles.
  • Black-and-White Morality: The victims who are forced to face off against the Corruption are always treated in a sympathetic manner in their attempts to fight back and stay alive. Mommy Mearest and Daddy Dearest who were initially villains in the original game are given an Adaptational Heroism and Adaptational Sympathy in battling the corrupted victims. The Corruption itself is malevolent force where it tries to have every character infected and locked within the depths of their mind, clearly cementing it as the main villain where every victim that not corrupted is fighting back for survival.
  • Black Blood: Boyfriend's bloody hand from having been shot by Evil Pico's bullet, Boyfriend's hand is shown to be bleeding Black Blood.
  • Blade Below the Shoulder: One of Nexus Pico's arms is a sharp crystal, which he uses to slash and stab at Boyfriend.
  • Blade Spam: Corrupted Pico uses his Blade Below the Shoulder to rapidly stab Boyfriend every time the beat of "Blood Moon" is dropping in a fast manner.
  • The Blank: Evil Boyfriend and Evil Girlfriend receive pixelated sprites in Week 6 where their faces completely disappear because of how they are corrupting the Hating Simulator game. Evil Boyfriend's Expressive Health Bar eventually loses a face once his body becomes too heavily corrupted to be stable.
  • Blank White Eyes: The end of "Headshot" and the beginning cutscene of "Blood Moon" begins with Pico's eyes becoming completely white in preparation to transform into the Nexus state.
  • Blue with Shock: If Boyfriend is feeling depressed and demotivated from rapping, he will slump down and feel blue from a lack of desire to combat the Corruption.
  • Body of Bodies: The Tank Amalgam is the result of an undead Tankmen horde jumping off the railings of a highway and merging themselves together to form one giant Tankman.
  • Bolivian Army Cliffhanger: Week 10 has Boyfriend, Pico, and Girlfriend be shaken from the undead Tankmen horde jumping around to form a large figure. As the figure slowly grows in size, the week ends with the announcement that the next opponent for the trio to face will be Tankman.
  • Boom, Headshot!:
    • Implied. Before Pico is corrupted by both Evil Girlfriend and Evil Boyfriend, there are implications that Pico shot himself in the head to stop the Corruption from using his body. Pico's attempt to shoot himself is made evident by how he point his gun into his head every time he uses his "left" animation during Week 4 and Week 7.
    • Subverted. Evil Pico tries to shoot Boyfriend in the head to finish him off, but fails because Boyfriend blocks the bullet with his hand.
  • Bottomless Magazines: Pico never runs out of bullets, whether it be from battling Boyfriend or the corrupted Tankman horde.
  • Brainwashed and Crazy: Subverted. The corruption was initially hinted to have mind-altering properties; Skid and Pico's body language while almost completely corrupted and Boyfriend's fight with Soul Boyfriend reveal that the corruption is instead its own "being", one that overtakes its victims and suppresses their conscious until it has total control.
  • Breaking Old Trends: The first five weeks of Friday Night Funkin': Corruption involves victims being targeted by the Corruption and whatever attempts they may try to fight back, the only outcome is that they always lose. The trend of having the victims lose is eventually broken once Boyfriend enters into the picture. Boyfriend is the first victim to successfully escape the Corruption and is given the main focus of saving others from the Corruption.
  • Broken Record: In contrast to the rest of the corrupted cast, Pico is only able to vocalize using lines from his songs from the original game, even if he's fighting another character in a new song.
  • Bullet Catch: In "Headshot", before Pico can shoot Boyfriend in the head, the latter is able to catch the speeding bullet with his hand, although the bullet does leave an open hole onto the hand.
  • The Cameo: Whitty prominently appears in the background of "Deathmatch" among the horde of corrupt individuals.
    • in the beginning cutscene of CHKDSK, Ross (one of the bullies from Spooky Month) appears for a few seconds before getting claimed by the Harvester.
  • Can Only Move the Eyes: Whenever a character has their body get heavily corrupted, the only body parts they can control are their eyes.
    • "Chiller" has Skid loses all control of his body and the Corruption forces him into an Involuntary Dance of having to do the Spooky Dance.
    • Pico's eye is the only body part he can control and express his emotions when the Corruption has taken almost full control over his own body.
  • Casual Danger Dialogue: During "Blood Moon", Girlfriend and Boyfriend briefly converse about tiring out Nexus Pico and then hitting him directly as Boyfriend is being attacked by him.
  • The Cavalry: A villainous example. After Daddy Dearest holds off the corruption for three songs straight, Pico, Skid, Pump, and Mommy Mearest all show up during "Deathmatch" to help Boyfriend corrupt him, and it's facing off against his corrupted wife that finally makes Daddy Dearest succumb.
  • Cavalry Betrayal: Mommy Mearest's henchmen, who were once her supportive backup dancers, betray her during her final fight against Evil Pico. In the Henchmen's corrupted state, they assist Evil Pico in ganging up against Mommy Mearest, which results in a Curb-Stomp Battle that she couldn't survive.
  • Cerebus Call-Back: In the original game, playing the tutorial on hard would end with a random string of voiceless notes, as a funny Easter Egg to screw with players. "Deathmatch" ends with a similar string of silent notes, as if corrupted Boyfriend is flaunting his victory over Daddy Dearest.
  • Cessation of Existence: Once Week 6's final song ends, Boyfriend gains admin control and deletes Senpai successfully, making him and Spirit the only characters to die rather than being corrupted like the others.
  • Character Blog: About a week after the release of the video for "Neuroses", a Twitter account was made for the opponent of Week 8, Soul Boyfriend, used to retweet fanart of the character and make humorous posts about guitars.
  • Chained by Fashion: In Weeks 4 and 10, Pico has a cross of chains bound to his chest. Word of God indicates that this is because Pico attacked a chain fence.invoked
  • Chekhov's Gunman: Mommy Mearest, who gets corrupted by Pico and disappears until "Deathmatch", where she is vital in corrupting her husband, allowing the corruption to spread across the entire world.
  • Christmas Episode: The aptly named "Christmas Special" is a short animation of skits based on each Week of the mod, given a Christmas and holiday coating.
  • Clothing Damage: The Corruption is not only capable of infecting the victim, but also their clothes as it spreads on their body.
  • Combat Pragmatist: Corrupted Pico tries to shoot Boyfriend in the head during "Extractor" when he realizes he's losing the battle. Emphasis on tries, since Boyfriend manages to actually catch the bullet in his hand. This still injures Boyfriend's hand, however.
  • Concert Climax: Daddy Dearest being the final victim for the Corruption to overpower takes place during the stage where he once battled Boyfriend. Daddy Dearest is faced off with dealing the entire army of corrupted victims and the event for his final battle is placed on his stage.
  • The Corruption: The titular corruption Monster unleashes is a tar-like substance that spreads across its victims, encasing them and taking control of their bodies. The fingers grow pink claws while the faces are replaced with wide-eye stares and Cheshire Cat Grins, also in pink.
  • Coup de Grâce Cutscene: The Tank Amalgam is only killed in a cutscene during the end of "Hivemind", when the Harvester intervenes in the song to do a Badass Finger Snap. Afterwards, a cutscene shows Tankman inflating, before exploding.
  • Covers Always Lie:
    • Downplayed. For "Deathmatch" the thumbnail and the title of the video says that it is a battle between Evil Boyfriend and Daddy Dearest. Although Evil Boyfriend is the main singer for Daddy Dearest to rap against, the thumbnail and title hides Evil Pico, Evil Skid and Pump, and Evil Mommy Mearest as supportive singers for Evil Boyfriend.
    • The thumbnails for Week 8 can give the impression that the opponent that Boyfriend is fighting is the Corruption, due to opponent's dark, colored body. It isn't until "Discharge" and "MEMORY//LEAK" to confirm that the figure is actually helping Boyfriend, despite the thumbnails making the figure look like a villain.
  • Creepy High-Pitched Voice: The Harvester, as shown in the cutscene before "Null and Void", turns out to have one of these.
  • Crocodile Tears: In Evil Girlfriend's illusion of pretending to have been broken free from the Corruption, she lets out fake tears to trick Boyfriend into thinking that he has saved her.
  • Cruel Mercy: Based on the Corruption's dialog in Week 8, it claims to have spared Boyfriend and wants him to remember their loyalty for each other. nevertheless, it is clear that the Corruption is only manipulating Boyfriend into giving up the desire to break free.
  • Cry Laughing: Played for Horror. "Chiller" has Skid's body be nearly corrupted and has him laugh in some sections of the song. While Skid's corruption laughs, his uncorrupted eye can only cry throughout the song.
  • Crystalline Creature: The Nexus state transforms corrupted victims into crystal versions of themselves as a way to have a hardened body for better fighting capabilities.
  • Curb-Stomp Battle:
    • Week 2 features Skid being forced to fight against Pump, Boyfriend, and Girlfriend. Considering that Skid is outnumbered and lacks any weapons or notable abilities to fight back, he is easily corrupted from being ganged up.
    • Throughout "Deathmatch", Daddy Dearest appears to be even with the Corruption, despite being forced to face an entire army of corrupted victims. However, once Mommy Mearest appears, he immediately becomes distraught over her corruption, which brings him to his Despair Event Horizon. With his resolve shattered, Daddy Dearest is quickly corrupted by Evil Boyfriend.
  • Curse Cut Short: During the final song of Week 8, Soul Boyfriend shouts "Now get out there and kick that guy's... ASS!", but Boyfriend regains consciousness right before he hears the "ass".
  • Dark Fic: Although Week 5 of the original game demonstrates a Vile Villain, Saccharine Show and Week 6 completely re-contextualizes the ongoing narrative in a much darker light, Corruption actively brings the undertones of both weeks into the forefront and throws the game's characters into a battle with genuine stakes and devastating consequences.
  • Dark Is Not Evil: While the shadowy Soul Boyfriend at first seems to be the darkness within Boyfriend's mind, and a force of the Corruption after his appearance in Week 6, Week 8's "Neuroses" has him reveal that none of this is his doing, while the following song, "Discharge", outright confirms that he has Boyfriend's best interests in mind, and assists him in breaking free of the Corruption's grip.
  • Dark Reprise:
    • "Sanguine South" is the first original remix to appear in the story, being a version of "South" that illustrates Skid and Pump's hopeless fight against the corruption.
    • The original "Senpai" is an upbeat track to lull the player into believing Week 6 was going to be a simple, fun romp; in contrast, the remix used for the mod is slower paced and contains heavy audio glitching, mostly from Boyfriend, playing into the horror aspects and how deranged Boyfriend has become.
    • The third song of Week 6, "Treacherous Thorns", is an even darker spin on an already foreboding track, showing that Senpai is done playing games and wants Boyfriend gone.
    • "Deathmatch", the climactic final song of Week 7, borrows motifs from several songs from the base game and "Chiller" from Corruption itself. Most notably, Corrupted Mommy Mearest sings the beatdrop from "MILF" as the final nail in the coffin against Daddy Dearest.
    • During "Discharge", the chorus of "Chiller" plays again as the Corruption loses its patience with Boyfriend and Soul Boyfriend, threatening the former.
    • At around the 1:50 mark of "Extractor", Boyfriend sings the instrumental of "Blammed" as a countermelody against the fully corrupted Pico.
  • Deadly Upgrade: The corruption can crystalize itself over its victim into its "Nexus" form; at the cost of sacrificing the vessel's ability to infect others, Nexus improves in both durability and offensive capability and changes the vessel's drive to infect into a drive to kill. However, the form does run on a time limit and causes the Corruption infecting the host to erode when it's nearing that limit, ironically making it easier to free someone from Corruption if they can endure the attacks.
  • Death by Adaptation: Downplayed. Friday Night Funkin' has its cast only battle Boyfriend and none of them truly die, except for a few characters. For this mod, the character aren't killed, but they are put into a state where their corrupted bodies consume them from ever being truly alive.
  • Death by Despair: In Daddy Dearest's furious state, he is capable of facing down Evil Pico, Boyfriend, and Skid and Pump, without showing any signs of rapid corruption. What truly causes Daddy Dearest to be defeated is when his own wife appears to cause him despair, resulting in his will completely dying. With no will to continue fighting, Daddy Dearest is easily corrupted by Evil Boyfriend with no difficulty.
  • Decoy Damsel: In "Dead Pixel" Senpai tries to save Girlfriend from Evil Boyfriend, but his attempts to save only save her turn out to be a horrible idea since Girlfriend and Boyfriend are actually working together to corrupt the Hating Simulator game.
  • Defeat Equals Explosion: Once Harvester snaps their finger, the Tank Amalgam is signaled into being defeated by inflating himself to explode.
  • Deliberately Monochrome:
    • The normally colorful arrows are all rendered gray with black splotches, as if the corruption has even managed to affect the UI.
    • Over the course of Week 6, the bright and colorful school grounds become darker and duller, until the only colors remaining are those of the characters.
  • Demoted to Extra: In the original game, Monster is an antagonist that personally battles Boyfriend and Girlfriend in "Monster" and "Winter Horrorland". However, in the Corruption mod, Monster only appears in the background of Week 2 and while he is implied to be the creator of the Corruption, Monster is never faced off.
  • Dented Iron: Downplayed. Boyfriend's battle against Evil Pico leaves him with a visible scar of where the bullet wound got through. While it does knock out Boyfriend for a bit, he is able to get back up to continue fighting, despite the injury that has been sustained.
  • Despair Event Horizon:
    • During "Roots", Spirit at first looks horrifyingly confident as he stares down Evil Boyfriend with the plan to bring him down, alongside the game. As the song nears its end however, Spirit returns back to his original Friday Night Funkin' sprite, showing his realization that Boyfriend has him outmatched.
    • Daddy Dearest is composed yet distraught for the first two songs in Week 7. "Deathmatch" sees him furiously fighting back against the Corruption's onslaught, determined to finally put an end to it, but being forced to fight against his corrupted wife instantly causes whatever willpower he had to fade. Evil Boyfriend soon returns to finish off Daddy Dearest, with the latter no longer fighting back.
    • During "Estranged", the corruption fooling Boyfriend into believing it instantly reserved his progress on uncorrupting Girlfriend causes him to spiral, cementaned by his health rapidly draining during this section. It takes Soul Boyfriend briefly returning to assist him for him to snap out of it.
  • Difficulty Levels: Compared to base FNF, this mod contains two of these:
    • "SAFE", which has the normal damage values for missing notes and allows Ghost Tapping to be of use.
    • "CANON", which has dynamic and more punishing damage for misses and turns off Ghost Tapping.
  • Disguised Horror Story: Week 6 initially begins like canon, complete with an apparently uncorrupted Boyfriend and Girlfriend. Then Boyfriend's text box is replaced with code commands of him trying to take admin control, and the song, Boyfriend, Girlfriend, and even the Background Freaks start heavily glitching out.
  • Disney Death: Boyfriend appears to have been shot dead by Evil Pico during "Headshot". The Corruption releases an Evil Laugh at Boyfriend's seeming death, only for him to get back up and reveal that only his hand was injured.
  • Don't Celebrate Just Yet: About halfway in "Headshot", Boyfriend celebrates his victory by posing with his hand, but by not focusing his attention on Evil Pico, Boyfriend is nearly shot in the head. Boyfriend luckily survives via using his hand to block the bullet that was about to reach his head.
  • Double-Meaning Title:
    • The mod's version of "South" is titled "Sanguine South" — the usual definition of "Sanguine" is "optimistic or positive, especially in an apparently bad or difficult situation", fitting for Skid and Pump's usual attitude. However, an archaic definition for the word is "bloodthirsty", an obvious reference to the Corruption's desire to further spread itself by any means necessary.
    • The second-to-last song of Week 8 is called "Discharge". "Discharge" can mean "to release an electric charge", referencing the electric guitars used throughout the song. It can also mean "to tell someone officially that they can leave", a nod to Soul Boyfriend snapping Boyfriend out of his delirium and helping him escape his own head.
    • The name of Week 9's first song is "Allure", meaning "the quality of being powerfully and mysteriously attractive or fascinating", an apt description for Girlfriend. It's also a homophone for "a lure", referencing Corrupted Girlfriend fooling Boyfriend into coming closer so she can attack him.
  • Downer Ending: Each week up to Week 7 ends with Corrupted Boyfriend's opponent being corrupted, or in Senpai and Spirit's case, outright dead. The final video for Week 7 then ends with the entire world being corrupted. Week 8 is the first week to break this trend, instead ending with Boyfriend freeing himself of the Corruption with Soul Boyfriend's help.
  • Dramatic Shattering: At the end of "Discharge", the bleak Mental World that Boyfriend has fallen into shatters apart like glass. Then Soul Boyfriend smashes his guitar onto the floor of the Womb Level from the first two songs, leaving them both in a White Void Room.
  • Duel Boss:
    • Downplayed. Week 3 and Week 6, Evil Boyfriend and Evil Girlfriend are paired up together to corrupt the opponents they are faced with. This is downplayed with the fact that Evil Boyfriend takes the lead in fighting his opponents, while Evil Girlfriend is on her speakers to bop her head.
    • "Treacherous Thorns" has Senpai and Spirit both altering the background of the Hating Simulator so they would both be able to work together in deleting Evil Boyfriend from their game world.
  • Early-Bird Cameo: Before the Harvester makes their official debut in "Hivemind", they made a brief appearance in "Headshot" to watch over Evil Pico and Boyfriend battle each other. As "Headshot" nears its end, Harvester flies out of the battle and eventually makes another, but official debut in "Hivemind, where they are given an animated cutscene to introduce themselves.
  • Early-Installment Weirdness: Due to the idea of a full-ass mod coming later, Week 5 is a simple sprite-swap without any real meaning, and thus lacks much of the details that appear in later weeks.
  • Earn Your Happy Ending: The first five weeks result in the Corruption completely overpowering the world, but a ray of hope happens with Boyfriend taking action to battle the Corruption.
    • Boyfriend's constant struggling inside his Corruption is put to an end with him working together alongside Soul Boyfriend to overpower the Corruption trapping them inside their mind. Soul Boyfriend and Boyfriend emerge triumphant in winning, making this event as the first time a victim overpowers the Corruption.
  • Empty Shell: Victims of the corruption have no genuine emotions or drive, only a simple-minded desire to spread it further. Week 8 implies that the victim is rendered dormant in their own mind until they awaken.
  • The End of the World as We Know It: After the defeat of Daddy Dearest from the Corruption, rather than his defeat say that he was "overpowered by Corruption", it instead says that the "world was overpowered by Corruption", thereby confirming that there are no more survivors to hunt down. Luckily, this ending is defied, once Soul Boyfriend and Boyfriend work together to overpower the Corruption that is trapping them inside their minds. Once they succeed in breaking free, Boyfriend works towards the goal of saving everyone that has been corrupted.
  • Energy Ball: The Nexus form of Evil Pico allows him to create dark, red balls of energy that are used to blast Boyfriend to death.
  • "Eureka!" Moment: In "Blood Moon", Boyfriend swinging his bloodied hand around gives him an idea on how he can utilize his bloodied hand to combat Evil Pico. As the song nears its end, Boyfriend commits to his plan by using his bloody hand to splash Evil Pico's eyes with some blood before punching Evil Pico in the face, allowing Pico to break free from the Corruption.
  • "Everybody Dies" Ending: The first five weeks of the Corruption results in everybody losing to the virus with Senpai and Spirit being killed off inside their game console, with the other survivors being completely corrupted. Even Daddy Dearest's Last Stand to fight the entire army of corrupted victims, ultimately results in his corruption, leading to the entire cast of characters to be overpowered by the Corruption. This ending is soon defied when Soul Boyfriend makes his entrance to free Boyfriend from his Corruption, leading to a story where he confronts corrupted victims to save them.
  • Evil Knockoff: The binary code next to Glitch Boyfriend in the image file for his portrait in the options menu translates to "You are a mere copy of me. An inspiration.", which implies that Glitch Boyfriend is not the same entity as Soul Boyfriend, but is instead an evil clone version of him born of the Corruption to take on Senpai and Spirit and stop them from intervening, explaining why Glitch Boyfriend does not have a tail like Soul Boyfriend does.
  • Evil Laugh: During "Headshot", The corruption forces Pico to shoot Boyfriend and laughs at Boyfriend's apparent death, until the latter gets back up to continue fighting again.
  • Evil Sounds Deep:
    • Corrupted Boyfriend speaks using a tone and voice effect that more closely resembles Pico's, sounding deeper and like it's been processed through a radio. This is most noticeable in less hectic songs like "Senpai (Glitch Remix)", where Boyfriend is noticeably off-pitch while Senpai is relatively the same.
    • Corrupted Skid and Pump's vocals in "Deathmatch" are audibly deeper in pitch compared to both their vanilla songs and the songs from Corruption Week 2.
  • Expressive Health Bar:
    • A character that is facing off corrupted opponents and is losing the opponents would result in their health bar being drained. A character having their health bar drained shows their expressions in reaction of their body being corrupted.
    • Averted. Soul Boyfriend's expression remains happy even when he is being overpowered by Boyfriend. This could have been a foreshadowing that Soul Boyfriend is not an enemy.
    • Evil Boyfriend's damaged health bar icon has his eyes be completely blacked out from being unable to keep up against his opponents.
  • Exotic Eye Designs:
    • While corrupted, Skid's eyes become bright pink Xs.
    • After getting corrupted completely, spirals swirl out of Pico's pupils to the edges of his eyes.
  • Eye Scream: After Boyfriend tries and fails to delete him, Senpai's eyes disappear from his face, as if they'd been gouged out. This does not deter him in the slightest - if anything, it just pisses him off further.
  • Eye Colour Change: A victim will have their eyes changed into a pink colour as part of their transformation into their corrupted selves.
  • Eyeless Face: The eyes of Evil Boyfriend disappear whenever his health icon is losing. When a game over happens for him, his entire face cracks and his eyes disappear.
  • Face Death with Despair:
    • For Skid, he doesn't get a chance to fight back at his corrupted opponents and is easily corrupted in the span of three songs. While getting corrupted, Skid is constantly crying as his main expression, and continues to do so even when he isn't able to control his own body.
    • In Daddy Dearest's final moments, his resolve and anger to completely fight the Corruption is destroyed from having to see his corrupted wife, resulting in a defeat where he has no will to continue fighting back.
  • The Faceless:
    • The Henchmen in "Schizophrenzy" only appear as Sinister Silhouettes throughout the entire song, which blocks their faces from ever being seen. The only part of face that can be seen is that their eyes are constantly glowing.
    • Evil Girlfriend's face in Week 6 gets blocked by a black screen and in her dialog box, a photorealistic eye can be seen replacing her face.
  • Face of an Angel, Mind of a Demon: The first song of Week 6 has Boyfriend and Girlfriend appear in a somewhat friendly manner in their pixelated forms. Senpai casually communicates with them, until they start to say glitched texts and their bodies start to deform. Senpai tries to save Girlfriend from Boyfriend's creepy glitching, but once it turns out that they are both endangering his game, Senpai and Spirit are forced to use their full powers in their attempts to fight them off.
  • Falling into His Arms: At the end of Week 9, Girlfriend, freed from the perch the Corruption put her on, falls to the ground, and Boyfriend quickly dives to catch her. He succeeds and Girlfriend gives him a thumbs up once she comes to.
  • Faux Affably Evil: Evil Girlfriend speaks politely in all of her songs, as she lures Boyfriend in a false sense of security and to drive his mind into insanity through her illusions. Her false tone of sophistication becomes apparent in "Estrange", as it is her desperate attempt to keep Boyfriend from winning.
  • Fearless Fool: After being trapped inside his own body and mysteriously woken up inside his own mind to fight against the corruption itself, and almost the entire cast visibly worried and suffering as they struggle, Boyfriend is the first character in the entire series to not give a single fuck, having a smug grin for the entirety of "Tormentor" and only being briefly startled by waking up. This is Played With as the series goes on, revealing that Boyfriend has genuinely been emotionally affected by what he's gone through and has a real fear he'll be unable to make things right, but powers through anyway with the hope that everyone can still be saved.
  • Feet-First Introduction: An animated scene that introduces the Harvester in "Hivemind" starts off by the latter stepping their foot onto the group. After making the step, the Harvester's face is shown and they are intrigued over watching Boyfriend, Pico, and Girlfriend fight the Tank Amalgam.
  • Fist of Rage: "Lament" and "Dusk" have Daddy Dearest clench one of his fist angrily as he battles Evil Boyfriend, despite the sadness and anger locked up within him.
  • Flunky Boss: Downplayed. While the other corrupted opponents that Daddy Dearest faces in "Deathmatch" can be considered bosses, Evil Boyfriend is clearly the lead of the song and is using the other corrupted opponents as his minions for reinforcement.
  • Forced to Watch: The eyes are always the last part of a victim's original self to go once the corruption overruns them, forcing them to watch as the rest of their body is transformed into an evil facsimile.
  • Foreshadowing:
    • In the original finale video for Week 3, the song was a mashup of "M.I.L.F." and "Blammed", initially odd considering "MILF" is one of Mommy Mearest's songs and that it is the only mashup in the mod's OST... until you get to Week 4, which has a fully corrupted Pico face off against her.
    • When Boyfriend initially tries to gain admin privileges in Week 6, the current admin is listed as a series of question marks. When Boyfriend attempts to delete Senpai during "Treacherous Thorns", his request is rejected, with the error textbox revealing that the current admin is Senpai himself.
    • Corrupted Boyfriend's appearance in Week 6 deviates significantly from his usual purple-and pink silhouette design; instead, his body is pitch-black, with a single glowing white eye and Jagged Mouth. It isn't until "Tormentor" in Week 8 that this is revealed to be an actual entity separate from Corrupted Boyfriend, with the cutscene leading up to final song "MEMORY//LEAK" revealing that he's a figment in Boyfriend's mind.
      Soul Boyfriend: "I'm not even real, you know?"
  • Foregone Victory: With Evil Boyfriend and Evil Girlfriend as the main protagonists of the story, the victims they face have no seemingly good chance in defeating them, as their opponents are usually on the losing side. The situation eventually changes in Week 8, when Boyfriend is Promoted to Playable in his fight against the Corruption. With Soul Boyfriend's help, he is able to break out from the Corruption and rescue Girlfriend.
  • The Fourth Wall Will Not Protect You:
    • Evil Boyfriend extends a claw towards the camera whenever he misses or otherwise gestures in his idle animations. Though it's obvious he's reaching for the player, it's not made clear why as part of the ongoing Ambiguous Situation regarding the self-control of victims.
    • Week 8 has Evil Boyfriend claw at the screen from having to watch its body uncorrupt itself from the power of Soul Boyfriend and Boyfriend singing together.
      • Evil Boyfriend looks directly at the screen with his Glowing Eyes of Doom to demotivate Boyfriend to stop resisting in "Neuroses".
    • In the Week 6 demo, attempting to play through the week again after completing it will cause your game to crash, as Senpai has been deleted and thus can no longer be fought. Starting the game back up after this will result in Corrupted Boyfriend requesting access to your computer. If you allow this, a .zip file titled 'BF_SOUL' will automatically be downloaded to your computer...containing a desktop pet of Glitch Boyfriend as he appears in "Roots".
  • Freeze-Frame Bonus:
    • In Week 8, the messages from the Corruption during "Discharge" briefly flicker into additional words that cause them to take on a much darker implication:
    How long has it been? Days? Weeks? Months? Years?
    Who are you waiting for? You don't even know.
    Let us take over. STOP RESISTING.
    We'll make you feel alive AGAIN.
    I WON'T ALLOW IT! YOU WILL STAY HERE!
    Don't forget. I spared you. Your loyalty.
    You will never see them again. They are dead - gone.
    You will regret this betrayal. YOU WILL DIE BY MY HANDS.
    • Once Boyfriend gets back up from Pico's gunshot during the song, "Headshot", a mysterious figure can be seen on top of a building in the background. Once the song ends, the mysterious figure shows its set of wings and flies away.
    • "Estranged" has written words on the wall that tells Boyfriend to give up fighting and it describes a plan to harvest a lot of souls.
    • Before starting "Headshot", dialogue can be seen that describes the Corruption's desire to prepare the harvesting of the souls of the victims that have been claimed.
  • Free-Range Children: Deconstructed; in their home series, Skid and Pump are two young children who go wherever they please with no adult supervision, and any threat they face is subdued by dumb luck. This ends up biting the two when the corruption begins to spread, as they're far from home with no one to protect them and no way to defend themselves.
  • From Bad to Worse: Typically, when a character is confronted by the Corruption, the infection that the character receives rapidly get worse over the course of their week. At the start of a week, characters will usually be fine but worried about the threat they are facing. For the second song, a tint of the Corruption can be seen spreading on the body of the victim. At the last song of the week, the victim has already lost the battle and can no longer resist the Corruption for any longer.
  • Futile Hand Reach: In Week 8, after Soul Boyfriend disappears at the end of "Neuroses", Boyfriend reaches out to where Soul was, and is met with silence. When Soul Boyfriend returns in "Discharge", Boyfriend reaches out again, only to met with a guitar to the face.
  • Game Face: In "Deathmatch", Daddy Dearest is grimacing with his his sharp teeth and Glowing Eyes of Doom on full display. Once he faces off against Mommy Mearest, he loses it and goes back to the sad look he has in "Lament" and "Dusk".
  • Gameplay and Story Integration: Deliberate Integration at the end of Week 6, where Senpai is permanently deleted by Corrupted Boyfriend. The game reflects this on the week selection screen, where his name and the footage of his week are replaced with 'NULL' and a permanent static screen, respectively. Furthermore, attempting to play the week again will crash the game.
  • Get A Hold Of Yourself Man: Soul Boyfriend reappears at the start of "Discharge" to toss a guitar at Boyfriend, breaking him out of his funk and inviting him to duet.
  • Giggling Villain: Throughout "Estrange", Evil Girlfriend is constantly giggling from dominating Boyfriend in their rap battle. As she causes him to go into a temporary Sanity Slippage, she giggles in his potential defeat. While she does eventually get overpowered by him later in the song, Evil Girlfriend giggles one more time in preparation for one more song.
  • Glass Cannon: The corruption can crystalize itself over a victim, greatly increasing its physical strength at the cost of losing its corruption ability and generally being far more fragile. Corrupted Pico uses this techiquie as a last ditch stand against Boyfriend.
  • Glowing Eyes of Doom:
    • In Week 4's third song, Pico's eyes have a white glow to them, and the now corrupted backup dancers are all black with shining white eyes.
    • During Week 6, the corruption showing through Boyfriend is all black, save for his shining white eyes and grin. This same appearance shows up during Week 8 in all its HD glory.
    • Boyfriend's eyes gain a white glow similar to Pico's while facing Daddy Dearest.
    • When he briefly appears during "Deathmatch", Skid has white glowing dots in the center of his eyes, simulating pupils.
    • Girlfriend's new sprites in "Allure" feature glowing white pupils, solely focused on Boyfriend.
    • The Nexus form of Evil Pico has his eyes turn into the Glowing Eyes of Doom. The eyes loses its pink colors and it becomes completely white, showcasing Evil Pico's desire to kill Boyfriend, rather than to corrupt him.
  • Glitch Entity: Spirit, Evil Girlfriend, and Evil Boyfriend are all entities that do not belong to the Hating Simulator game.
    • Spirit makes his appearance in "Treacherous Thorns" via glitching his way into teaming up with Senpai. Spirit's teamwork with Senpai allows them to gain a better advantage in fighting off Evil Girlfriend and Evil Boyfriend.
    • Evil Boyfriend has himself be turned into a Glitch Entity by having his soul be directly transferred into the game, resulting in its would being corrupted. Having his soul be transferred allows Evil Boyfriend to replace his seemingly friendly sprite into a dark, malevolent being with the goal of killing Senpai and Spirit.
    • As shown in "Null and Void", Senpai himself has become this with the destruction of the Hating Simulator. "Null Senpai" is little more than an Ominous Visual Glitch that occasionally reforms into a version of himself covered in rainbow-colored pixels. And he still has Spirit inside him.
  • Go Mad from the Isolation: Downplayed. Boyfriend loses the hope to hold onto his will to fight off the Corruption in his body, because of Soul Boyfriend's absence to bring out his confidence. Once Soul Boyfriend returns in "Discharge", Boyfriend regains to will rap again and reject the Corruption from his body.
  • Good is Not Nice: While Soul Boyfriend is ultimately on Boyfriend's side and plays a vital role in helping him break free of the Corruption, his methods tend to be rude and aggressive. Notably, he roars at Boyfriend to forcibly wake him up at the beginning of the week, constantly taunts and belittles him throughout "Tormentor" and the first half of "Neuroses", and even flings a guitar at his head to snap him to attention when he returns for "Discharge". At the end of "MEMORY//LEAK", he decides to uppercut Boyfriend in order to knock him back to reality.
  • Greater-Scope Villain: While the Boyfriend is the main threat to the rest of the characters, Monster is the one who initially released the virus and corrupted Boyfriend and Girlfriend in the first place. He can also be seen watching through the window when lightning flashes during Week 2.
  • Gotta Get Your Head Together:
    • "Tormentor" has Evil Boyfriend hold his head together with his hands from having to feel the pain of Soul Boyfriend and Boyfriend working together to break free from the Corruption.
    • During the first half of "Estranged", Boyfriend holds his head together to keep his focus on saving Girlfriend from the corruption, even though she is driving him mad with the corruption.
  • Guns Are Useless: To Boyfriend and the horde of dead Tankmen, Pico's Uzi guns are able to hurt them and he is confident over blasting his enemies. For the Tank Amalgam, Pico is worried over the height of his enemy and whatever shots he fires, they do nothing to hurt Tankman.
  • Guns Akimbo: Evil Pico's appearance in Week 10 has him gain another Uzi compared to when he only had one Uzi in the previous weeks.
  • Gun Twirling: Pico spins his Uzi guns in the air while he continuously battles the undead Tankmen that are approaching him, Boyfriend, and Girlfriend.
  • Hand Behind Head: Boyfriend puts his hand behind his hand, once he approaches "Girlfriend" in "Allure". As he nervously walks towards her with the belief that she has been saved, "Girlfriend" takes the opportunity to try and stab him, which Boyfriend barely avoids.
  • Happy Ending Override: Implied. Considering that Boyfriend remembered a Precious Photo of the Dearest family smiling happily together alongside with Pico, and Skid and Pump, they may have all befriended each other in the past, until The Corruption ruined everything.
  • Healing Factor: Although characters are capable of healing themselves from the corruption or save victims from the corruption, Daddy Dearest proves himself to be self-sufficient at healing himself. Even faced with Evil Boyfriend and a horde of corrupted victims, Daddy Dearest is able to constantly heal himself from the corruption whenever it infects his body, but can only fail from meeting his wife, causing him to go over the Despair Event Horizon.
  • Heart Beats out of Chest: The Nexus form of Evil Pico has his heart be exposed outside of his chest and is seen beating.
  • Heartbeat Soundtrack: The Sequel Hook for "Deathmatch" and the intro for "Tormentor" both have the sound of a beating heart. The heart could signify Boyfriend being given focus as the main character to escape the Corruption holding his body.
  • The Heavy: Although Monster is implied to be the creator of the Corruption virus, as it originated from his "Winter Horrorland" song, he only makes a minor appearance in Week 2. Evil Boyfriend on the other hand is one of the victims that the Corruption had claimed and is given lots of focus on his goal of corrupting a majority of the FNF casts.
  • Helpful Hallucination: Soul Boyfriend implies before "MEMORY//LEAK" that he's not real, but just a part of Boyfriend's mind. Despite this, he plays a huge part of freeing Boyfriend from the Corruption, even if he's quite rough around the edges.
  • Hero Antagonist: With Evil Boyfriend as the Villain Protagonist that seeks to corrupt all of the FNF cast, the remaining victims act antagonistic towards all of the Corruption in an effort to save everyone that the virus has infected. The trope is eventually inverted into the Hero Protagonist, once Boyfriend is Promoted to Playable in his journey to break free out of his Corruption.
  • Heroic BSoD: Boyfriend goes through a traumatic event from the Corruption taking away Soul Boyfriend in "Neuroses", leaving himself all alone. In the moments where Boyfriend is alone, he loses the determination to break free from the Corruption, until he is able to call Soul Boyfriend to return for a second time.
  • Heroic Second Wind:
    • After losing confidence and weakly clinging to what remains of himself, Soul Boyfriend reappears and snaps Boyfriend out of his funk, setting the stage for the two fighting against the corruption together and, for the first time in the series, succeeding.
    • In "Estranged", Boyfriend begins to spiral when it seems like the corruption instantly reverses the progress he made with uncorrupting Girlfriend, going so far down even his healthbar begins to rapidly drain. Soul Boyfriend then appears behind Boyfriend, giving him the push to realize it's another illusion before going right back to giving it his all.
  • Hidden Agenda Villain: The closest the Harvester comes to being a villain is when they kill off the Tank Amalgam and soon afterwards, extracting his souls from dying. Other than a texts on the wall, the Harvester's motives to collecting souls are left unknown.
  • Hidden Eyes:
    • Once Evil Girlfriend starts to glitch in Week 6, her facial portrait shows that only one of her eyes can be seen through her blank face. The only eye showing appears to be a photorealistic image from the result of the Hating Simulator being destroyed,
    • Evil Girlfriend's illusion in "Allure" briefly hides her eyes, as she prepares to lure Boyfriend into a false sense of security.
  • Homage: In Week 8, "Discharge" serves as an extended love letter to Guitar Hero (specifically Guitar Hero III), being a heavy metal song that has several parts of its chart done in an odd number of keys rather than the standard four of FNF and changes the UI to resemble that of the game series during those sections. It also borrows the main guitar solo portion from "Through the Fire and Flames," Guitar Hero III's most iconic song, at one point.
  • Hope Crusher: Corrupted Mommy Mearest ends up being this to Daddy Dearest. Although Daddy Dearest is able to resist Corrupted Boyfriend, Pico, and Skid and Pump, he loses the will to continue fighting once he sees his corrupted wife. Daddy Dearest's grief distracts him from the battle, eventually allowing Evil Boyfriend to corrupt him.
  • Hope Spot:
    • The second song of Week 3 sees Boyfriend breaking through his corruption and singing alongside Pico in an effort to free themselves completely. In the final song of Week 3, Boyfriend has not only been reconsumed, but Pico's own corruption has worsened, and he loses himself completely after the song finishes.
    • The second song of Week 4 shows that while Mommy Mearest has now been corrupted by Pico, Pico himself has managed to peek through his corruption enough to show an uncorrupted eye, hinting that he's still Fighting from the Inside, only for him to revert back to being fully corrupted on the final song as Mommy Mearest is taken over herself.
      "He's still in there, somewhere..."
    • Both the second and third song of Week 7 showcase Daddy Dearest managing to resist and push back the corruption while having to deal with every single corrupted cast member one by one in the third song. He manages to do well against Boyfriend, Pico as well as Skid and Pump until he ends up facing his now corrupted wife, causing his will to keep going fade as the corruption finally and quickly manages to take over.
    • In the middle of the first song of Week 9, Girlfriend is seemingly freed of the corruption. Boyfriend begins to happily approach her, but it's quickly revealed to be a ploy by the corruption, one that Boyfriend catches wind of before Girlfriend is able to harm him.
  • Horned Humanoid: Soul Boyfriend's powered up form gives him white horns on the top of his head as he battles Boyfriend in "Neuroses".
  • Horrible Judge of Character: When the Harvester appears to Boyfriend in the cutscene before "Null and Void", Boyfriend's first instinct is to happily shake the Monster Clown's hand.
  • Hour of Power: The Nexus form provides the corrupted victims greater physical abilities to kill its enemies. One major drawback the Nexus state has is when used for prolonged periods, it can result in the transformation cracking, making the state only useful for ending a battle as quick as possible.

    Tropes I-W 
  • I Cannot Self-Terminate: Skid has a bloodied handprint on his right temple in "Chiller", while the corrupted Pico has blood splatters on his face and points his gun towards his head instead of the ground in his animation for hitting a right-facing note; both suggest that they tried to self-mutilate or take their own lives to stop their bodies from being used, but somehow failed.
  • I'm a Humanitarian: At the start of Day 2 of the Null fight we see Evil Skid eating up Lila (AKA his mom).
  • Immediate Sequel: At Week 8, Boyfriend after breaking free from the Corruption is forced to face off Evil Girlfriend right away for Week 9. Although Boyfriend succeeds in saving Girlfriend, he is immediately confronted by Pico, resulting in another fight happening. In Boyfriend's journey to stop the Corruption, the weeks take place immediately right after he fights off against a corrupted victim.
  • The Immune:
    • Zig Zagged. Senpai and Spirit is completely immune to Evil Boyfriend's corruption, as the former is shown to not be getting corrupted throughout the progressing songs that Evil Boyfriend is singing. Although immune to the Corruption, Senpai and Spirit require their cybernetic world protected in order to continue surviving. Rather than to have both of them be corrupted, Evil Boyfriend instead deletes them from existence.
    • Downplayed. Daddy Dearest is not completely immune to the Corruption, but he has a powerful Healing Factor that allows him to greatly resist any form of corruption on his body.
    • Implied. For Boyfriend, rather than have his body be corrupted by Evil Girlfriend, he appears to be somewhat fine in battling her, except for his nervousness. Even when he starts to lose his mind from the corruption, nothing from his body shows that he is being corrupted, which could implicate that Boyfriend is gaining resistance, as shown from how he is able to see through Evil Girlfriend's illusions.
  • Immune to Bullets: As a undead Tankmen army, they are not able to withstand Pico's bullets and have to merge themselves together as the Tank Amalgam to stand a chance. As a singular giant Tankman, he can tank all of Pico's bullets and Boyfriend's supporting raps do nothing in hurting Tankman.
  • Impaled Palm: To protect himself from getting shot in the head by Evil Pico, Boyfriend quickly moves his hand to have it take the brunt of the bullet that almost hit his head. While Boyfriend does succeed in surviving the gunshot, it leaves a hole on the palm and is shown to be leaking Black Blood.
  • Imposter Forgot One Detail: When Girlfriend becomes "uncorrupted" in "Allure", she's noticeably wearing her usual outfit instead of her Christmas attire. Boyfriend realizes this as he gets closer, and quickly moves out of the way before she can harm him.
  • Instant Waking Skills: Soul Boyfriend loudly awakens Boyfriend by screaming at him to wake up. Upon Boyfriend being awoken from his sleep, he is completely prepared to rap battle his way to escape the Corruption. When Boyfriend wakes up for having gained control of his body back, he quickly captures his microphone and celebrates his victory.
  • Interface Screw:
    • In the guitar sections from "Discharge", your notes change into those of Guitar Hero and you lose the right receptor. Not like there are any right notes to hit in these sections, anyway.
    • In "MEMORY//LEAK", your streamline is split into two, with the left and down notes on the left side and the up and right notes on the right. Your receptors also become invisible.
    • In "Null and Void", Null Senpai gets the worst of it in the game so far — he can move your receptors all around the screen and even between the foreground and background, changing the directions where the notes come in from, and more.
  • Interface Spoiler: The portion of the videos showcasing the stages always end in asking the viewer to subscribe for the next video, with the second video of each Week using "final battle": if the second video instead uses "next battle", it's a sign there's something else going on.
    • In the second "Pico vs Mom" video, this was because the following video was a momentary perspective shift depicting Boyfriend's first match against Senpai, with the final "Pico vs Mom" video being released the week after.
    • In the second "Boyfriend vs Senpai" video, this is because Senpai has four songs, not three - the third video is instead the one to use "final battle".
  • In the Style of: "Dead Pixel" is "Roses" in the style of the soundtrack for the Friday Night Funkin': Neo mod, being made by the same composer.
  • Involuntary Dance: Throughout "Spookeez" and "Sanguine South", Skid primarily clings onto Evil Pump, as they both rap against Evil Boyfriend. However, during "Chiller" when Skid is heavily corrupted, his body forces him to do the Spooky Dance out of his will.
  • It Can Think:
    • During "Discharge", the Corruption starts speaking, threatening Boyfriend into succumbing to its influence once again. As he and Soul Boyfriend continue through the song, it gets more and more desperate.
    • During Week 9's "Allure", Corrupted Girlfriend actively sets up a trap for Boyfriend: she uses an illusion to trick him into thinking that she's been freed from the Corruption, then encourages him to come closer so that she can impale him with her Tendrils of Darkness. When Boyfriend narrowly evades the attack, she chuckles faintly.
  • I Will Find You: At the start of "Discharge", Boyfriend sings all alone to call out for Soul Boyfriend to return and motivate him to continue rapping. By singing all alone, the Corruption questions Boyfriend on who he is waiting for and is commenting how futile it is to keep trying. Eventually, Boyfriend succeeds in calling Soul Boyfriend when the latter shatters the environment.
  • Jitter Cam: The camera shakes every time the Nexus form of Evil Pico unleashes a slash attack that can slice the air. The attack is so strong that Boyfriend has to focus on dodging it and the camera reacts by shaking wildly.
  • Karma Houdini Warranty: The first five weeks portray Evil Boyfriend as an invincible corrupted victim that is constantly overpowering his opponents. No matter what the survivors do, Evil Boyfriend always emerges victorious, until he leads the world into being overpowered by the Corruption. The Corruption of Evil Boyfriend finally gets his well-deserved defeat, once Soul Boyfriend and the real Boyfriend are awakened to take control of their own body.
  • Killed Off for Real: While the corruption is ridiculously hard to get rid of, it isn't incurable, meaning the characters affected could theoretically be freed from it. Senpai however is deleted, with the game in shambles and his code unrecoverable, making him and Spirit the only characters in the mod to outright die.
    • In the cutscene preceding "CHKDSK", it's revealed that Lila is a goner too, having been killed by her own son and her flesh bitten into.
  • Leitmotif: With the exception of "Strength of Will" and "MEMORY//LEAK", all of the songs in Soul Boyfriend's week, and "Estranged" in Week 9, feature Saster's, one of the mod’s composers, personal leitmotif.
  • Killer Finale: Week 3, 2, 4, 6, and 7 all have the common theme of the surviving victim lose to the Corruption by the last song of their respective weeks.
    • For Pico, he appears to be doing well in uncorrupting Boyfriend in the second song, until the last song comes and reveals that Pico's Corruption has gotten a lot worse. Along with Boyfriend becoming fully corrupted again, Pico is guaranteed to lose in the end of his week.
    • Skid never really had a chance to combat the Corruption in his week, as he was completely outnumbered by three corrupted enemies and can only rely on Evil Pump to help him sing. Throughout the course of the week 2, Skid's Corruption only grows worse and by "Chiller", Skid is almost fully corrupted and has lost control over his own body.
    • Though Mommy Mearest got slightly corrupted in "M.I.L.K.", she at least barely uncorrupted an eye of Pico and appears to be doing well in rap battling him. However, once "Schizophrenzy" comes in, Mommy Mearest gets over half of her body corrupted, corrupted versions of her Henchmen come to haunt her, and her attempts to save Pico have all been in vain.
    • Senpai and Spirit both lose to Evil Boyfriend in "Root", since the latter corrupts the game so badly that he ends up gaining admin controls. Once Evil Boyfriend becomes an admin, he chooses to have Senpai and Spirit deleted by the end of their week.
    • At first, Daddy Dearest does well in handling Evil Boyfriend and all of his corrupted allies in the first half of "Deathmatch". Nonetheless, Daddy Dearest's efforts are still All for Nothing, as Evil Mommy Mearest is what causes his will to wear down, which gives Evil Boyfriend the chance to beat him.
  • Last Stand: Daddy Dearest acts as the last obstacle for the corruption to confront and infect. He ends up being the World's Strongest Man that forces the entire corruption army to face him down and is able to last very well, until having to meet his wife. As Daddy Dearest is quickly getting corrupted, he continues to rap against Boyfriend, until the song ends, revealing that the entire world was corrupted.
  • Last Villain Stand: For the Corruption to use its Nexus form, it needs to pushed into a corner where the chances of victory is unlikely. For this reason, the Corruption has Pico use the Nexus form against Boyfriend, believing him to be too dangerous to continue living or corrupting.
  • Late-Arrival Spoiler: Before getting onto the Corruption series, you might notice images of Boyfriend fighting off corrupted victims in the thumbnail, spoiling his escape from the Corruption and him reclaiming the role as the Hero Protagonist.
  • Light Is Good: The shining light that Boyfriend and Soul Boyfriend are creating in "Discharge" is beneficial for allowing Boyfriend the chance to shatter the darkness that the Corruption created inside his mind.
  • Light Is Not Good: Evil Boyfriend and Evil Girlfriend inside the Hating Simulator game looks bright and colorful in their pixelated state. Senpai tries to give them a proper greeting, but despite Boyfriend and Girlfriend's friendly-looking appearance, they are clearly dangerous entities that seek to harm Senpai and Spirit based on the dialog box.
  • Lightning Reveal: When lightning flashes in the window during Week 2, Monster's silhouette appears, revealing he's watching Boyfriend fight Skid and Pump.
  • Lonely Piano Piece: In Week 8's soundtrack, the intro to "Discharge" is in fact a separate song on the OST named "Strength of Will", a brief segment consisting of a lone, hollow-sounding synth keyboard to represent Boyfriend's struggle to keep going.
  • Loud of War: The survivors and the Corruption all use music as the main means of combating each other. The Corruption spread via singing to the victims, while the victims sing back to survive and potentially free the ones that are trapped inside the Corruption.
  • Loving a Shadow: One of Evil Girlfriend's lines in "Estrange" has her say "that's the you I want to see" to Boyfriend. Her desire to corrupt him may be related towards her twisted love for Evil Boyfriend.
  • Made of Evil: Implied. Whenever the Corruption infects a victim, the victim is always forced to spread it to other characters. Characters who have been completely corrupted lose all control over their bodies, allowing the Corruption to take full control of it. As shown in Soul Boyfriend's week, Boyfriend is locked deep within his mind and is constantly being suppressed to not break free.
  • Made of Iron: Downplayed. Even when Boyfriend is shot in the hand by Pico's gun, the former is still able to continue the fight, although the bullet does drain Boyfriend's health bar.
  • Major Injury Underreaction:
    • Double Subverted. The beginning cutscene for "Treacherous Thorns" begins with Senpai acting nervous and demanding both Evil Boyfriend and Evil Girlfriend to leave his game. However, when Evil Boyfriend rips off Senpai's eyes, the latter loses his composure and isn't actually bothered from having his eyes removed. What deleting Senpai's eyes instead does is that he fights even harder to kill Evil Boyfriend.
    • Downplayed. Around halfway in "Headshot", Evil Pico shoots Boyfriend's head, giving the impression that Boyfriend had died. Luckily for Boyfriend, he catches the bullet with his hand, but not without sustaining some serious damage. Despite the pain, Boyfriend is still capable of letting out a confident smile to continue fighting. Even when Boyfriend shakes his bloodied hand, he ends up enduring the pain to blind Evil Pico in the eye and defeat him.
  • Marathon Level:
    • "Discharge", the third song of week 8, is over five minutes long, much longer than any song in the base game or in the mod itself.
    • "Estranged" is a little under five minutes long, longer than any song in the base game and second-longest in the mod next to "Discharge": the song is primarily composed of quick back and forths or out and out duets between Boyfriend and Corrupted Girlfriend, leaving little breathing room for the player.
  • Mass "Oh, Crap!": Boyfriend, Pico, and Girlfriend all become nervous by the end of "Brainstorm" and at the start of "Hivemind" over the Tank Amalgam forming behind them.
  • Meaningful Background Event: After Boyfriend gets back up in "Extractor", a shadowed figure can be seen standing on a building in the background. At the song's end, the figure leaps off the building.
  • Meaningful Echo: During "Brainstorm", Boyfriend and Girlfriend happily cheer on Pico by shouting "Go Pico!", similar to how Pico hyped himself in Week 3 of the base game by singing "Go Pico".
  • Men Ac T Women Are: For the cast composing the main protagonists, Boyfriend and Pico are on the front lines in fighting off the Tank Amalgam in "Hivemind". Girlfriend, meanwhile, the sole female of the group is only bopping her head and cheering them from behind.
  • Mickey Mousing:
    • While not initially noticeable, Corrupted Girlfriend twitches her head to the song every other beat.
    • Corrupted Pico attacking Boyfriend in "Blood Moon" is timed to beats in the music.
  • Mind-Reformat Death: Like in canon, Daddy Dearest trapped Spirit into the Hating Simulator years before the events of the mod, turning him into data and locking him behind Senpai's code. When Boyfriend gets into the game, he attempts to corrupt said code, then tries to delete Senpai outright when he resists. Senpai and Spirit fight back but ultimately lose, and Boyfriend deletes their data before breaking the game entirely.
  • Moment Killer: Once Boyfriend saves Girlfriend from her corruption, they both hug themselves to recover from their battle. Their heartwarming love is ultimately cut short once Evil Pico shoots the stage in his attempt to kill them.
  • Monochromatic Eyes:
    • The eyes of Soul Boyfriend are left completely blank when confronting and rap battling Boyfriend.
    • Evil Pico's eyes become completely blank when he activates his Nexus form to better combat Boyfriend as a last resort.
  • Monster Clown: The Harvester, an Original Character who appears in Week 11 to "play a game" with Boyfriend — and by "play a game", they mean sending him back into the broken Hating Simulator to battle with Null Senpai.
  • Mood Whiplash:
    • Week 6 begins with the usual dialogue for Boyfriend and Senpai, until Boyfriend says a code command that clips out of the text box.
    Senpai: Ah, a new fair maiden has come in search for true love!
    Boyfriend: Beep bo bop
    Senpai: A serenade between gentlemen shall decide where her beautiful heart shall reside.
    Boyfriend: void StartTransferal(Soulbf_soul){ switch (admin) { case"user": admin == "???"} GrantOwnership(admin) Console.Write("You are next.")
    Senpai: ...
    • The 2021 "Christmas Special" is a series of skits juxtaposing the dark nature of the mod with the usual holiday events one would expect from Christmas, with things like Daddy Dearest dejectedly sitting by the fire with a mug before being enraged at the corrupted Boyfriend, Pico, and Skid and Pump breaking into his house, or Skid and Pump about to give each other presents and Skid fearfully hiding behind his once Pump gets corrupted.
  • Mook Chivalry: "Deathmatch" has Evil Boyfriend, Evil Pico, Evil Skid and Pump, and Evil Mommy Mearest attack Daddy Dearest one at a time despite having an entire army to sing at the same time.
  • My God, What Have I Done?: When Pico partially breaks free of the Corruption's hold on him in "Extractor", his uncorrupted eye has a clear look of horror after realizing he shot Boyfriend, while the rest of his corrupted self laughs.
  • My Name Is ???: The title name for Week 8 is written in three question marks, probably to hide the true nature of Soul Boyfriend or the Corruption inside the depths of Boyfriend's mind.
  • Mysterious Watcher: After Boyfriend gets up from Evil Pico's shot in "Head Shot", a Mysterious Watcher appears in the background to watch Boyfriend and Evil Pico fight. The figure eventually leaves when "Head Shot" nears its end.
  • Near-Villain Victory: The Corruption succeeds in overpowering the entire world in infecting all of the remaining victims throughout its 5 weeks of rampage. Week 8 is where the Corruption starts to deal with a serious loss, as Boyfriend becomes conscious inside of its own mind and begins to start breaking free, leading into a storyline where he saves the corrupted victims.
    • The Corruption itself nearly succeeds in overpowering Boyfriend's will to break free, but loses when Soul Boyfriend reminds Boyfriend to continue fighting for his friends. The reminder brings out Boyfriend's confidence again and wins in taking control of his body back.
  • Neck Snap: Corrupted Girlfriend bends her head enough to crack her neck before "Allure" begins proper while screaming in agony.
  • Nerves of Steel:
    • Pico and Mommy Mearest approach the corruption head-on and calmly persevere even as it latches onto them. It's implied that keeping a cool head actually slows down the conversion process, as Pico stays half corrupted for two songs while the scared out of his wits Skid goes from uncorrupted to fully corrupted over the course of three.
    • Daddy Dearest remains composed if distraught throughout most of Week 7, in turn keeping the corruption near completely at bay; it is only when he is confronted by the corrupted Mommy Mearest that his resolve breaks, and he is swiftly taken over.
  • Neutral Female: Throughout Week 3, 2, and 6, Evil Girlfriend mainly sits on her speaker and lets Boyfriend do the fighting when it comes to corrupting their victims. Evil Girlfriend's status as a Neutral Female is subverted since she is the first opponent Boyfriend faces once he is freed from his own corruption. Once Girlfriend is freed from her own corruption, she strategizes with Boyfriend on taking down Evil Pico's Nexus form during "Blood Moon".
  • Nice Mean And In Between: The main protagonists of this mod have their niceness and meanness vary for different characters. Boyfriend is the nicest in the group for never holding out grudges and dedicating his life into freeing people out of the Corruption. Pico is the meanest for punching Boyfriend in revenge, despite the latter saving him from the Corruption. Girlfriend is in-between, as she only becomes violent over seeing Boyfriend get hurt.
  • No Body Left Behind: Zig-Zagged: As a group of undead Tankmen, their dead bodies are shown to pile up into a mountain of corpses if nothing is done to them. However, after they all merge themselves to become Tank Amalgam, they die in a explosion to eradicates whatever piece of their body.
  • "No More Holding Back" Speech: The end of "Dusk" has Daddy Dearest announce to Evil Boyfriend of no longer wanting to go easy on him.
  • No Mouth: Corrupted Pico's Nexus form has him lose his Scary Teeth, implying that he lost the ability to corrupt others.
  • Non-Lethal K.O.: In "Blood Moon", Evil Pico gets punched in the face by Boyfriend and is successfully freed from the Corruption. Pico is briefly knocked out from the punch, but is able to get back up and fight the horde of Tankmen.
  • No-Sell: After Senpai tells them to leave, Boyfriend attempts to delete his data, only to find that Senpai has administrator privileges — he denies the request and is incredibly pissed off at the attempt.
  • Nothing Is Scarier: The week selection screen includes footage previewing the gameplay of each week...except for Week 8, which is simply titled '???' and shows Corrupted Boyfriend slouching listlessly as in the cutscene before "Tormentor". The soundtrack also fades out to little more than a mechanical ticking sound, a pounding heartbeat, and echoing ambiance to add to the ominous atmosphere.
  • Not Me This Time: Implied by Soul Boyfriend during the second phase of his battle with Boyfriend, as he states that 'this isn't my doing', referring to the corruption encroaching on the battle. This is one of the first hints that he isn't part of the corruption and is on Boyfriend's side.
  • Not Quite Dead: Boyfriend and Soul Boyfriend appear to be doing well in breaking free from the Corruption, because it isn't being an active threat towards them. The situation quickly becomes worse once Evil Boyfriend stares at them and Boyfriend slowly starts to lose his focus.
  • Not So Invincible After All: The Corruption proves itself to be an incredibly powerful force that manages to successfully wipe out the entire FNF cast. Even when Daddy Dearest unleashes his full power, he ultimately succumbs to it from his broken resolve of having to face his own wife. After the defeat of Daddy Dearest, the corruption proves itself to be Not So Invincible After All once Boyfriend and Soul Boyfriend are able to break out from their own corruption. Afterwards, Boyfriend is able to successfully free Girlfriend and Pico in their fights.
  • Master of Illusion: Week 9 reveals that like Monster, the Corruption is able to create illusions to fool its victims, shown with corrupted Girlfriend nearly duping Boyfriend into thinking he uncorrupted her.
  • Oh, Crap!: After "MEMORY//LEAK", Boyfriend has a wide-eyed panicked expression on his face, similar to when he woke up at the start of Week 8, as Soul Boyfriend prepares to punch him out of his mindscape.
    • On the while Girlfriend is Searching Boyfriend unaware of the fact that BF is in the now-glitched up Hating Simulator fighting Null Senpai, she does a big one as she looks terrified by seeing her corrupted mother coming towards her.
  • Ominous Cube: Harvester has a floating black cube on top of their hand and it reacts with Tron Lines from having absorbed white particles from the death of the Tank Amalgam.
  • Ominous Fog: "Extractor" has the highway be covered in fog to give off a creepy atmosphere for Boyfriend's battle against Evil Pico.
  • Ominous Obsidian Ooze: The corruption is a dark purple substance that spreads across its victims; upon encasing them completely, it takes them over and uses their bodies to further spread itself. Those consumed are given a Healing Factor and are capable of supernatural feats their normal selves would never be able to do.
  • Ominous Visual Glitch:
    • Due to taking place within the Hating Simulator videogame, Week 6 features heavy use of visual and audio glitching; for the first song, it's to contrast the normal bright nature of the dating sim with the corruption, with everything going screwy as corrupted Boyfriend messes with the game. The corruption itself is presented as black pixels glitching over and covering the character sprites.
    • "Extractor" has its musical beats be in sync whenever a glitch occurs in Evil Pico's battle against Boyfriend. The glitching of the song is accompanied by fog clouding the battlefield to demonstrate the mysterious atmosphere.
  • One-Man Army: While Daddy Dearest also acts as the World's Strongest Man, he is also capable of facing down an entire army of corrupted victims by himself, without showing signs of rapid corruption on his body. In the end, the only reason he loses is when his hope breaks from seeing his corrupted wife.
  • One-Winged Angel:
    • In its final stand to keep Boyfriend from uncorrupting her, the Corruption tosses aside Girlfriend's speakers and props her up with wings and tendons made from corruption ooze. Girlfriend's voice also heightens in pitch, sounding similar to her mother.
    • Pico nearly breaks free from the Corruption's grip at the start of "Blood Moon"; its hold deepens to stop him, and the result becomes an entirely new form taking cues from Soul Boyfriend, with a sleek purple body and crystals covering his hands, one of which is formed into a spear.
  • O.O.C. Is Serious Business: A firmly established fact of the series is that fully corrupted individuals are driven to further spread the Corruption to anyone they can find. Corrupted Girlfriend's attempt to skewer Boyfriend in "Allure" implies that the Corruption no longer has any intent to corrupt him, but rather wants him dead outright to prevent him from fixing everything. When Boyfriend sees through the Corruption's illusions and frees Girlfriend, it sends Corrupted Pico in to finish the job.
  • Ornamental Weapon: In Week 3, despite Pico holding an Uzi in his hand that can be useful in his fight against Evil Girlfriend and Evil Boyfriend, Pico never bothers trying to shoot them with the weapon. Even in Week 4, Evil Pico still doesn't use his gun to hurt Mommy Mearest and instead only focuses on rapping to corrupt her. This is averted in Week 10, as Evil Pico succeeds in nearly killing Boyfriend by attempting to shoot his head. Once freed Pico is freed from the Corruption, he actively uses his guns and puts them to good use in fighting the undead Tankmen horde.
  • Original Character:
    • Week 8 introduces a character that wasn't introduced in the original Friday Night Funkin', and the character called "Soul Boyfriend" is a seemingly malicious entity that trying to suppress Boyfriend's will to combat the Corruption. However, "Neuroses", "Discharge", and "MEMORY//LEAK", reveal that Soul Boyfriend is a Helpful Hallucination that is actively assisting Boyfriend in escaping the Corruption.
    • another Original Character introduced to this mod that wasn't in the original game is called the Harvester. They make their official appearance in Week 11 to watch over the ensuing battle between the Tank Amalgam against Boyfriend, Pico, and Girlfriend. By the end of "Hivemind", the Harvester kills Tankman with a Badass Finger Snap, but the reasons for doing so are unknown.
  • Other Me Annoys Me: Hidden binary can be found in the Week 6 demo that translates to Soul Boyfriend calling the copy of him that appears in "Roots" little more than just that, further confirming he's on the side of good.
  • Outside-Context Problem: In a flip of the original Week 6, Senpai and Spirit are completely blindsided by the corrupted Boyfriend and Girlfriend, having no context on the two or what's been going on outside the game, only that they have malicious intent and their mere presence is destroying the Hating Simulator.
  • Painting the Medium:
  • Partial Transformation: Usually in the second song of a week, a victim fighting against the Corruption will have a part of their body partially corrupted before it completely spreads in the third song of the week.
  • Perpetual Frowner: Daddy Dearest is constantly frowning in his battle against Evil Boyfriend, signifying his lack of hope from having lost everyone he loved and rage against the corruption.
  • Perpetual Smiler:
    • Alongside with having a Slasher Smile, all corrupted victims are smiling in a malicious way as they rap to corrupt more victims.
    • Soul Boyfriend is constantly smiling in his rap battle against Boyfriend, as if he wants Boyfriend to be encouraged to continue fighting back.
  • Please, Don't Leave Me: By the end of "Neuroses", Soul Boyfriend leaves and Boyfriend is left all alone of his own corrupted mind. Without Soul Boyfriend to sing and backup his confidence, Boyfriend waves in despair to try bringing back Soul Boyfriend. Luckily by "Discharge", Boyfriend's singing and refusal to give into the Corruption is able to bring back Soul Boyfriend.
  • "Pop!" Goes the Human: The Tank Amalgam's body swells up from a finger snap of the Harvester commanding him to die. As Tankman continues to swell, bright lights begin penetrating his body, before exploding into oblivion.
  • Power at a Price: The Corruption's Nexus form can make its victims gain the offensive abilities to fight others, but the Corruption will lose its abilities to corrupt others. Not to mention, the Nexus form is a transformation that is not sustainable, because of its heavy energy usage for it to be maintained.
  • Power Glows:
    • Soul Boyfriend shows himself to be getting stronger in some parts of "Neuroses" during the moments where he glows white strips around his body.
    • Inverted. A purple aura surrounds Boyfriend in "Discharge", as a way to weaken his will to fight back for control over his own body. Boyfriend regains his confidence when the purple glow goes away and a Precious Photo of his friends appears.
  • Power of Friendship: As Boyfriend slowly loses his hope at breaking free from his corruption, a Precious Photo appears in front of him and it cheers him up to continue fighting. In the precious photo, Boyfriend sees Girlfriend, Daddy Dearest, Mommy Mearest, Pico, Skid, Pump, which encourages him to continue fighting for their safety.
  • The Power of Rock:
    • Winning a music battle against a corrupted character uncorrupts them, at least partially; in contrast, losing a battle against a corrupted character will cause the loser to corrupt or speed up their conversion if they already are corrupting.
    • "Discharge" is a more literal variant, as Boyfriend and Soul Boyfriend duet on both vocals and electric guitars throughout the heavy metal song until doing so causes the realm from Week 8 to completely and utterly collapse.
  • Power Floats: In the final song of Week 6, Corrupted Boyfriend has entered the game completely and is hovering off the ground to signify his own power and the otherworldly nature of the corruption. Soul Boyfriend also floats in Week 8, more noticeable due to BF still being on the ground.
  • Precious Photo: In Week 8, Soul Boyfriend telling Boyfriend to remember his friends is accompanied by a photo of Girlfriend's parents, Girlfriend, Pico, and the Spooky Boys smiling for the camera, implying the main cast set aside their differences and learned to get along before the Corruption took it all away.
  • Pre-Explosion Glow:
    • For how Girlfriend and Pico were freed out of their Corruption, a glowing white light appears on their corrupted bodies, before the Corruption is shattered into pieces which frees them.
    • As the Tank Amalgam is inflating in size from the Harvester doing a Badass Finger Snap, Tankman gains glowing lights penetrating his body. Eventually, the penetrating lights causes Tankman to explode.
  • Prehensile Tail: In Boyfriend's mind, Soul Boyfriend has a devil-style tail that he uses to hold his microphone in his left and down poses.
  • Promoted to Playable:
    • In Week 4, the player takes control of corrupted Pico in order to battle against and corrupt Mommy Mearest.
    • In the final battle for Week 7 against Daddy Dearest, the player shifts in control for the corrupted Boyfriend, Pico, Pump and Skid, and Mommy Mearest.
    • After spending the entire game playing as corrupted characters, Week 8 sees the player taking control of an uncorrupted Boyfriend to do rap battle with Soul Boyfriend, and ultimately teaming up with him against the Corruption itself in the week's finale.
    • Throughout Week 10, Boyfriend spends a majority rap battling Evil Pico, until having successfully freed the latter from The Corruption. With Pico freed from his corruption, he takes the final song, "Brainstorm", as the main lead in fighting the undead horde of Tankmen.
  • Psychosomatic Superpower Outage: Depending on Daddy Dearest's mood, his powers can fluctuate from either his depression of having his loved ones be taken away and his anger towards the corruption. In his enraged state, his powers reaches its peak, allowing him to battle an entire army of corrupted victims, while not showing any signs of fatigue. The only reason he loses in the fight is because of his powers being suppressed from having witnessed his corrupted wife, resulting in his Despair Event Horizon.
  • Purple Is Powerful: Zig Zagged. The Corruption makes Pico go One-Winged Angel to increase the chances of defeating Boyfriend. In the Corruption's transformed state, it results in Pico becoming a crystalized purple version of himself. The transformed state of the Corruption is called the "Nexus" form and it causes the host to become more powerful, but at the cost of losing the ability to corrupt others. The Harvester, however, primarily dresses in purple and is capable of blowing up the Tank Amalgam in one Badass Fingersnap.
  • Psycho Pink: Downplayed. The pink tints on corrupted victims only cover a small portion of their body, but it does contribute to show their feral behavior to corrupt more characters.
  • Psychotic Smirk: As Evil Girlfriend lures Boyfriend into dropping his guard, via illusion of pretending to be saved, she lets out a small, malicious smile in preparation of stabbing him with her Tendrils of Darkness.
  • Quaking with Fear:
    • The final song of Week 3 has Pico constantly shake his corrupted hand that is holding his Uzi. Pico's constant trembling of his hand showcases his desperation and fear of how the Corruption is getting close to overpowering him.
    • As Boyfriend finally breaks out of his corruption, he celebrates his victory, but it comes to a sudden halt from seeing Evil Girlfriend. Seeing her corrupted causes Boyfriend to shake in fear for the incoming battle he has to get ready.
  • Rage Breaking Point:
    • Senpai loses his cool and becomes much more serious in killing both Girlfriend and Boyfriend when the latter tries to have him get deleted. Boyfriend having failed to delete Senpai, Senpai only gets irritated from how his eyes were removed, causing him to rap more intensely.
    • Although "Lament" and "Dusk" clearly show Daddy Dearest in his distraught and angered state, he mainly acts composed in battling Boyfriend. Daddy Dearest truly reaches his Rage Breaking Point in "Deathmatch" when he stops holding back and opts to go using his full powers.
    • The Corruption itself goes through a Villainous Breakdown to constantly fill Boyfriend's head with lies to shatter his will to break free. The Corruption desperately forces thoughts on how Boyfriend's friends are dead and how they are bounded together by their loyalty.
  • "Ray of Hope" Ending: In the aftermath of Daddy Dearest's defeat to the Corruption, the Corruption of Evil Boyfriend is shown to be cracking, implying that there is still a chance for Boyfriend to come back.
  • Razor Wind: One of Evil Pico's attacks in his Nexus form is to unleash powerful slashes that can slice the wind at incredible speeds to hurt Boyfriend.
  • Recycled Soundtrack:
    • Week 3 and the first song of Week 2 consist of fan Friday Night Funkin' remixes that were created separately from and are completely unrelated to the mod, repurposed to fit the context. Following the first song of Week 2, Phantom Fear brought on musicians to create new music specifically for the mod, starting with "Sanguine South".
    • "Yandere Attack" is an existing song from Etherflux's BOSSFIGHT album, remixed by the original composers and with Boyfriend and corrupted Girlfriend singing over it.
  • Red and Black and Evil All Over: Victims of the Corruption have their bodies covered in a black substance and are laced with pink spots. The appearance of the Corruption makes its victims become mindless with the only goal of wanting to spread it to other characters.
  • Red Eyes, Take Warning: While Daddy Dearest has bright red eyes by default, both he and his character icon repeatedly shift between them being visible or not during "Lament", "Dusk" and "Deathmatch".
  • Red Filter of Doom: A red filter appears in the entirety of "Headshot", showing Boyfriend's battle against Evil Pico is becoming more dangerous and intense compared to the previous song.
  • Red Sky, Take Warning:
    • "Sky" is subjective in this case, but as Boyfriend's Battle in the Center of the Mind intensifies during "Neuroses", the dark greyish-purple of his Mental World starts to glow red. This happens again when the Corruption attempts to reassert itself in "Discharge", with the addition of the ground taking on a cracked, volcanic appearance.
    • "Blood Moon", fitting its name, sees the sky turn a bright red after the corrupted Pico takes his new form. When Pico is freed, the sky returns to normal.
  • Removing the Head or Destroying the Brain:
    • Implied. In "Yandere Attack", Boyfriend tries to uncorrupt Girlfriend throughout the song. By the end of the song, the only part of the Corruption left is attached to her head, and when that's gone, she is freed from it for good.
    • At the end of "Blood Moon", Boyfriend decks Pico square in the face, causing the Corruption to completely break off after its otherwise indestructible death grip on Pico's body.
  • Rescue Hug: After Boyfriend successfully frees Girlfriend from the Corruption, they both share a hug with each other to celebrate their victory, but it quickly gets interrupted with Evil Pico shooting the stage.
  • Rewatch Bonus: Viewing Week 8 for the first time without any context can give the impression that Soul Boyfriend is the Corruption that is holding back Boyfriend from escaping. However, after viewing "Discharge" and "MEMORY//LEAK", the two songs reveal that Soul Boyfriend is actually supporting Boyfriend in escaping the Corruption by acting as The Rival. Rewatching "Tormentor" and "Neuroses" confirms that Soul Boyfriend's dialog is to enforce Boyfriend's confidence to rap harder.
  • The Rival: Invoked; Soul Boyfriend acts as Boyfriend's opponent, but not for any malicious reasons. His ultimate goal is to challenge Boyfriend in a way that reignites his will to keep moving in spite of The Corruption so they can escape together.
  • Rockers Smash Guitars: At the end of "Discharge", after the bleak landscape shatters away to reveal the setting of the previous two songs, Soul Boyfriend and Boyfriend smash their guitars into the ground, breaking everything entirely.
  • Rotten Rock & Roll:
    • Week 8's first three songs are all rock tracks, featuring heavy amounts of electric guitar in their instrumentation. The week's opponent, Soul Boyfriend, even manifests an electric guitar to perform the guitar solos in "Neuroses" and "Discharge" In-Universe. The 'rotten' part is ultimately subverted, however: while Soul Boyfriend initially appears malevolent, he turns out to be anything but, helping Boyfriend break free from the Corruption through a guitar duet.
    • Week 9's "Allure" shifts to electric guitar-centric instrumentation similar to Week 8's songs midway through. This is a straighter use of the trope: unlike Soul Boyfriend, Corrupted Girlfriend is definitely ill-intentioned, attempting to straight-up kill Boyfriend rather than just corrupt him again.
  • Rule of Three: For a victim to get corrupted, it usually takes three songs for them to be completely consumed by the Corruption. The first song mostly features the victim in their worried state and are usually in their normal state. The second song has the Corruption partially spread onto the victims body, before the third song nearly consumes them.
  • Rhymes on a Dime: Unique to this mod's interpretation of Senpai is that he rhymes every other sentence: in addition to his base game dialog rhyming "decide" and "reside", his dialog in "Dead Pixel" has him rhyme "distance" with "mistress" while threatening Boyfriend. Him abruptly dropping this quirk in "Treacherous Thorns" is a tip off that Spirit has taken control of him.
  • Sanity Slippage: During the first half of "Estrange", Boyfriend slowly loses the will to fight and eventually his sanity to save Girlfriend. With Evil Girlfriend creating illusions of his inability to save her, Boyfriend quickly becomes a Stepford Smiler as an attempt to reinforce his hopes, despite having his energy being drained by her. Luckily, he rises up from his Sanity Slippage with Soul Boyfriend's return to back up his hopes, giving Boyfriend the ability to see through the Corruption's illusions.
  • Scary Teeth: The mouths of corrupted characters resemble Monster's: numerous rectangular (or triangular for Girlfriend's parents) teeth put in the general pattern of a constant grin. The exceptions to this are Pump and Skid, who instead have rows of white, shark-like teeth and a Jagged Mouth, respectively.
  • Security Cling: In "Spookeez" and "Sanguine South", Skid holds tightly onto Evil Pump, as they rap in battling against Evil Boyfriend. However, once the corruption has greatly infected Skid, he is unable to grasp his hands onto Pump and is forced to do the Spooky Dance, until being corrupted fully.
  • Sequel Hook:
    • Before "Deathmatch", every video that was not the final video of each week always ended with "The battle isn't over yet! Subscribe for Part (insert number here)!"
    • The final scene of Week 10 is the hordes of corrupted Tankmen jumping off the bridge and seemingly forming together. (probably into a Body of Bodies) In the final Week 10 video, this is followed by "Next time... Tankman".
  • Series Fauxnale: "Deathmatch" was heavily teased to be the final song of the mod by the creators... until The Stinger, which was followed by the start of Week 8.
  • Shout-Out:
    • After Week 10's final song "Brainstorm" was released on YouTube, the song's composer Leebert would confirm in the comment section that he incorporated motifs from Terraria Calamity into the instrumental.
    • When Boyfriend is sent back into the broken remains of the Hating Simulator during "Null and Void", the sequence is quite visually similar to when the heroes of Deltarune enter the Dark World in Chapter 2.
  • Shows Damage: The Nexus form of Evil Pico is shown to be tiring out by his sprite changing throughout "Blood Moon". The Nexus form tires out the longer it is used against Boyfriend and the damage being shown is the result of Pico's body cracking from the energy strain.
  • Silence Is Golden: Zig-zagged: the story is majorly told via the stage and characters physically changing over the course of the Week, but like the original game, Week 6 has text cutscenes alongside the aforementioned stage evolution; occasionally, characters will also "speak" via lines of text showing up during the songs themselves, like the end of "Dusk" or during parts of Week 8, and Soul Boyfriend's lines in "Discharge" are outright voiced, as is Girlfriend's attempt to seduce Boyfriend in "Allure" and "Estranged" and her taunting of him in the latter.
  • Singing Voice Dissonance: Whenever a victim of the Corruption has their face corrupted, their voice becomes distorted when they sing their notes. The dissonance in the victims voice may be the result of the Corruption covering their mouths.
  • Single-Stroke Battle: As "Blood Moon" nears its end, Evil Pico prepares to unleash a powerful Blade Spam, but Boyfriend is able to counterattack Evil Pico's attack with his blood, before delivering a powerful punch that frees Pico from the Corruption.
  • Sinister Silhouettes:
    • The Henchmen in "Schizophrenzy" have their entire bodies completely shadowed in the background, only allowing their Glowing Eyes of Doom to be seen. Besides the eyes of the Henchmen, their bodies are completely darkened and they dance in an almost static way as they assist Evil Pico in corrupting Mommy Mearest.
    • As Evil Girlfriend grows out her Tendrils of Darkness, her entire body is completely darkened from the transformation until it is complete.
  • Skyward Scream: Corrupted Pico starts the song, "Blood Moon", by screaming loudly at the sky. His scream is so strong that it changes the entire atmosphere into purple.
  • Slasher Smile:
    • All of the major corrupted characters sport a wide grin showing all their teeth: in particular, Pump's shark grin is on full display for all of his animations, making him look gleefully unhinged.
    • Spirit has a large teeth-baring smile during "Treacherous Thorns" and "Roots".
    • Corrupted Boyfriend's expression alternates between an even wider smile and an agonized expression during "Tormentor" in Week 8.
  • Slow Transformation: Downplayed. Whenever a victim is in the process of having their body corrupted, it usually takes an entire week for them to completely lose to the Corruption. A usual week has three songs for a victim to sing, while their entire body is slowly being covered up by the Corruption.
  • Small Role, Big Impact: Although Mommy Mearest only appears in one segment in "Deathmatch", she is the necessary component for the Corruption to truly overpower Daddy Dearest's will. Her appearance is what destroys Daddy Dearest's anger and it what allows his corruption.
  • Snowy Screen of Death: Week 8 has provides a static screen in Boyfriend's mind and the corrupted body of Boyfriend inside the static screen is the one that is experiencing its corruption slowly fading away from Boyfriend and Soul Boyfriend's efforts to break free.
  • Sole Survivor: Through four weeks of rampage, the Corruption has succeeded in corrupting Pico, Skid and Pump, Mommy Mearest, and killed Senpai and Spirit. The only survivor that remains is Daddy Dearest hiding inside his stage, yet despite his best efforts to fight the Corruption, he ultimately succumbs to it, just like the other victims. However, this trope is defied once Boyfriend escapes his corruption, leading to his story of saving the corrupted victims.
  • Speaking Simlish: Subverted. Inside the game console, Boyfriend initially interacts with Senpai through "beeping and bopping" in his words. However, Boyfriend's casual way of speaking quickly ends up being the language of codes through the process of inserting his soul inside the game.
  • Speed Echoes:
    • At some point during "Headshot", Evil Pico raps so fast that it creates multiple images of him.
    • Once Evil Pico transforms into his Nexus form, speed trails of his own character follow behind him, signifying his increased speed in order to be more combative.
  • Spikes of Villainy: Evil Pico's Nexus form makes his body even spikier that before, signifying him as a much more dangerous threat because of his better combat abilities.
  • Staring Down Cthulhu: Besides Girlfriend, Pico and Boyfriend are prepared to look into the eyes of the Tankman Amalgam to stare him down in "Hivemind". Boyfriend always has a smug smile on his face to look at Tankman and Pico is blasting as many bullets as he can to hurt Tankman.
  • Stealing the Credit: Boyfriend, Pico, and Girlfriend all believe that they were responsible in having killed the Tank Amalgam by the end of "Hivemind", since they were the only ones present. However, unbeknownst to them, the Harvester who is looking from afar is the one that actually killed Tankman with a snap of a finger.
  • Stealth Mentor: Soul Boyfriend is portrayed as an antagonist that is constantly judging Boyfriend's ability to rap and is given the impression of being the actual Corruption in "Tormentor". While Soul Boyfriend is eventually revealed to be Good All Along, he still remains an antagonistic rival to continue pushing Boyfriend into escaping the Corruption.
  • The Stinger:
    • Before the final video for Week 7 premiered, it was teased as the final battle of the whole mod, even ending with the words "The world was overpowered by Corruption", until the very end where the words "Next time..." appear and Soul Boyfriend appears, grinning at the camera. The video ends with the words "Subscribe for the next part!"
    • After Boyfriend's Battle in the Center of the Mind during "Tormentor", the video cuts to the outside world, the camera focusing on a rather cracked-looking Corrupted Boyfriend. The last shot of the video is of Corrupted Boyfriend, still cracked, looking at the camera... with part of his head uncorrupted.
    • At the end of the Null Senpai Video there are two, the first is the infamous moment when Senpai dies and Spirit shows up but it's glitched up, and the second is when GF searches BF but gets taken by surprise by Mommy Mearest.
  • Sudden Gameplay Change: Parts of "Discharge" are charted in 3K (omitting the right arrow) and play the song's strings rather than vocals, with the UI changing to resemble Guitar Hero.
  • Suddenly Shouting: The first note that comes out of Evil Pico's Nexus form is that he is Suddenly Shouting, resulting in the entire atmosphere turning purple.
  • Suddenly Voiced:
    • Soul Boyfriend begins speaking actual lines during "Discharge" and "MEMORY//LEAK", courtesy of one of the mod's composers, Saster.
    • Girlfriend speaks during the illusion midway through "Allure" and in parts of "Estranged" courtesy of one of the mod's directors, PincerProd.
    • The Harvester gets a voiced cutscene in full Japanese before "Null and Void".
    "So you're the one I was told about... I have heard a lot about you... AND I DON'T LIKE IT. I know! Let's play a game!" (JP: 「君が噂の・・・君の事をよく聞いているよ。まったく気に入らないけどね。わかってるさ!ゲームをしよう!」)
  • Sudden Soundtrack Stop: Downplayed. The soundtrack theme for Week 8 is present, but unlike the previous weeks before it where the music is a Dark Reprise of the original Friday Night Funkin', Week 8's theme is the sound of a ticking clock.
  • Summon Backup Dancers: Played for Drama; due to the much more serious tone, Mommy Mearest's backup dancers normally present during Week 4 are absent for the first two songs. They suddenly appear during the final song, corrupted and motionless save for the occasional twitch. Unlike other corrupted characters, their eyes are a bright, glowing white; as Pico's eyes are also glowing when they weren't before, it's implied he somehow called them over, as if to mock Mommy Mearest.
  • Super-Persistent Predator: Corrupted characters will do anything they can in order to spread the corruption onto others. In particular, Boyfriend forced himself and Girlfriend into Senpai's Dating Sim simply so they could corrupt it.
  • Super-Reflexes:
    • Before getting stabbed by Evil Girlfriend's Tendrils of Darkness, Boyfriend quickly reacts before he is hit, allowing him to continue fighting her, although it does cause him to get nervous from the betrayal.
    • Boyfriend showcases his Super-Reflexes on his ability to dodge the attacks of Evil Pico's Nexus form. While the form grants Evil Pico lots of combat abilities, Boyfriend successfully dodges all of them and wins the battle by directly punching Pico in the face.
  • Sweat Drop: Surviving characters that are feeling nervous or desperate in fighting off their corrupted opponents will let out a small Sweat Drop on one side of their face.
  • Take My Hand!: During "Yandere Attack", Boyfriend attempts to grab Girlfriend's uncorrupted hand before going back to singing. Towards the song's end, when the corruption has been reduced to her head and parts of her hair, Girlfriend reaches out to Boyfriend, revealing she's regaining control of herself. Boyfriend moves to grab her hand, leading into the final part of the song.
  • Taking You with Me: When Spirit realizes Boyfriend has screwed with the game so much it's going break no matter what they do, he attempts to take Boyfriend down with him, and fails.
  • Tareme Eyes:
    • Boyfriend's usual Tsurime Eyes will become droopy if he is feeling depressed or nervous about having to fight off the Corruption.
  • Tears of Blood: Corrupted characters cry pink, and any normal tears that roll over corruption will turn pink, as shown with Skid.
  • Tears of Fear: Throughout Week 2, Skid is constantly crying from the fear of having his entire body corrupted from facing off against his opponents. His cries continues even when he is forced to do the Spooky Dance under the control of the corruption.
  • Tendrils of Darkness: Corrupted Girlfriend manifests four black tentacles around her speakers midway through "Allure". She puts them to use later in the song by attempting to skewer Boyfriend with them.
  • Transformation Horror: The Corruption spreading towards the body of its victims causes them to either cry in pain or be worried as to what their body is slowly transforming. In Skid's case as an example, he is constantly crying from the Corruption rapidly spreading and once it nearly corrupts him, he ends up losing almost all control of his body and is forced to dance in his last moments.
  • Transformation Sequence: Before starting "Blood Moon", Evil Pico grows crystal spikes out of his own body and changes his colors into purple. The transformation allows Evil Pico to reach the Nexus state, a state where he has better attack abilities despite lacking the ability to corrupt others.
  • Tron Lines: The Ominous Cube that floats around the Harvester's hand temporarily gains glowing lines from having absorbed the energy particles coming off the Tank Amalgam's death.
  • Tsurime Eyes:
    • Soul Boyfriend's eyes are always slanted and sharp, giving the appearance that he is confident in his goal to push Boyfriend into gaining the will to overpower the Corruption.
    • Boyfriend himself will have slanted eyes whenever he is feeling optimistic and prepared to confront the Corruption.
  • Twitchy Eye: During Week 10, Corrupted Pico's left eye twitches in his idle pose, most likely either an outside indicator of the Corruption's effect on Pico's Schizophrenia or the Corruption displaying it's anger at Boyfriend's stubborn refusal to give up.
  • Two-Faced: A partially or heavily corrupted victim will show their corrupted face, as well as their uncorrupted face that is being slowly consumed by the Corruption.
  • Two Guys and a Girl: Boyfriend and Pico serve as the two guys for forming up one of the main characters. Girlfriend is the only girl between them that fills up the female section of the trope.
  • Two Lines, No Waiting:
    • The first video of Week 6 was uploaded before the final video of Week 4; within the context of the narrative, Pico is fighting his final bout against Mommy Mearest whilst Boyfriend is infiltrating the Hating Simulator videogame to have a match against Senpai.
    • The Stinger of Week 11's "Null and Void" appear to set this up again. With Harvester successfully teleporting Boyfriend back into the Hating Simulator to battle with Null Senpai and Spirit, Girlfriend is now vulnerable to attack from the corrupted Mommy Mearest...
  • Unkempt Beauty: After Girlfriend is thrown into the road and is knocked out unconscious during the aftermath of Week 9, she still remains beautiful in her unconscious state, despite having some dirty markings.
  • Unseen Evil: Although Monster is heavily implied to be the creator of the Corruption, since the virus is based off his "Winter Horrorland" song, he never directly appears onscreen to confront his victims. The closest he gets to confronting his victims is when lightning flashes reveal his silhouette in Week 2, as a way to corrupt Skid.
  • Unwitting Instigator of Doom: Girlfriend's parents fighting Boyfriend during Week 5 sets the stage for Monster's takeover and the events of the mod, as not only does it give him the opportunity to nab Boyfriend and Girlfriend and corrupt them, but also gives him a mall full of unsuspecting people as a perfect ground zero to release the virus.
  • Vampire Refugee: Week 3 sees a half-corrupted Pico fighting against the fully-corrupted Boyfriend. While he puts up a good fight, Pico succumbs shortly after losing his third song.
  • Versus Character Splash: Each Corruption video Phantom Fear uploads on his channel showcases a surviving character on one side, while the other side shows the corrupted victim. On the middle of the the thumbnail, a "VS" sign is added to indicate that both the characters will be fighting for either survival or for the Corruption to spread.
  • Victim of the Week: Week 3, 2, 4, 6, and 7 all have different characters be put into situations where they have to fight for their lives against their corrupted opponents. However, every week always results in a Downer Ending, as the Corruption always succeeds in claiming the lives of its victims.
  • Victory Fakeout:
    • About halfway through "Allure", Boyfriend appears to have saved Girlfriend from her corruption and she asked him to approach her, so they could celebrate their victory. However, it turns out to be a ploy of the Corruption in an attempt to stab Boyfriend, while his guard is down.
    • In the second half of "Headshot", Boyfriend celebrates his victory in the middle of battle against Evil Pico, believing to have won, but is quickly shot in return. Boyfriend appears to have been Boom, Headshot!, but he is luckily able to Bullet Catch with his hand.
  • Villain Protagonist: Corrupted Boyfriend is the main villain of the narrative, with him being the playable character in almost all of the weeks aside from Week 4, where the player takes control of Corrupted Pico, and the final video for Week 7 where the player swaps controls between almost the entire corrupted cast. Subverted for Week 8, which instead has the player control Boyfriend while facing off against Soul Boyfriend, and eventually teaming up with them against the Corruption.
  • Villainous Breakdown:
    • During "Discharge", the Corruption starts talking to Boyfriend in an effort to keep him under its control. Its messages get increasingly menacing as the song goes on, and by the end, it's outright sending him death threats.
  • Villainous RRoD: The Corruption's Nexus form offers a large power boost at the cost of the form erroding over time, potentionally allowing whoever it's affecting to be freed should someone get a clear shot in. It also seems to cause a toll on the body itself, as Corrupted Pico takes noticable breaks between each burst of attacks.
  • Violence is the Only Option: Corrupted Pico opts using his Nexus form to kill Boyfriend rather than corrupt the latter, due to Boyfriend being Too Powerful to Live to choose re-corrupting him.
    Corruption: You will regret this betrayal. YOU WILL DIE BY MY HANDS.
    • After the events of Week 8, the Corruption stops trying to break Boyfriend and starts actively trying to kill him. It starts by trying to use illusions to fake him out, but by the end of Week 9, it's sending Pico in to try and shoot him and the newly uncorrupted Girlfriend.
  • Volcanic Veins: Soul Boyfriend has white glowing lines on his body in "Neuroses", whenever he is being temporarily powered up during his rap battle with Boyfriend.
  • V-Sign:
    • Boyfriend holds out a V-Sign as he holds his microphone in triumph from having overpowered the Corruption taking hold of his body.
    • Boyfriend lets out another V-Sign during the midst of battle against Evil Pico and celebrates his supposed victory over dominating Evil Pico in the fight. Boyfriend's decision to celebrate turns out to be a bad idea, as Evil Pico takes the opportunity to have Boyfriend shot while off guard.
  • Walking Spoiler:
    • The existence of Soul Boyfriend and his appearance in Week 8 is what changes the tides in allowing Boyfriend to overcome the Corruption that is trapping them. Soul Boyfriend initially gives the impression as the villainous figure that is supposedly corruption Boyfriend, but the reveal that he is an ally is a major spoiler that shows that Boyfriend is not alone in fighting the Corruption.
    • The mysterious Monster Clown, Harvester, appears starting in Week 11, seemingly as a mischievous villain who wants to separate the party and render Girlfriend vulnerable to a corrupted Mommy Mearest.
  • What Happened to the Mouse?: Throughout the mod, Girlfriend is in the background twitching along to the beat. She abruptly disappears during the final song of Week 6, and her unexplained absence continues into Week 7. She is also mysteriously absent from the Christmas special despite it covering Weeks where she was present. She finally shows up in The Stinger for "MEMORY//LEAK"'s video, and serves as the rival for the entirety of Week 9.
  • What If?: The entire story asks what if the severed head in "Winter Horrorland" wasn't just for show, and answers that hypothetical scenario with a full-blown Zombie Apocalypse.
  • Where It All Began: "Deathmatch", the Series Fauxnale of the Corruption mod takes place in the very first week where Boyfriend fought Daddy Dearest. The entire battle is located inside Daddy Dearest's concert and all of the corrupted victims arrive in the stage by shattering its background wall, forcing Daddy Dearest to fight every victim that has fallen in battle.
  • White Void Room: As "Discharge" nears its end, Soul Boyfriend and Boyfriend's intense music they had created was so strong that it shattered the bleak Mental World of the Corruption. With the mental world dramatically shattering from the two's singing, it results in the background becoming a White Void Room. In the white void, there is nothing left for the Corruption, so Soul Boyfriend and Boyfriend both use their guitars to smash whatever is left of the white void.
  • The Whole World Is Watching: The video for "Dusk" ends with a text box stating "Everyone is watching us". In the following video for "Deathmatch", there's a giant hole in the wall showing hordes of corrupted people watching Daddy Dearest fight Boyfriend. The end of the video sees the entire world corrupted after Daddy Dearest succumbs.
  • Wingding Eyes:
    • Averted. Unlike in the original game, the character icons on the health bar keep the character's eyes as they are and simply show the corruption spreading when the icon nears the edge. The exception is the first fight against Mommy Mearest, whose lose icon still depicts her snarling with X's for eyes.
    • Skid's corruption plays the trope for horror. His lose icon for "Sanguine South" has the corrupted side of his face with a pink X for an eye: come the third song, and it's revealed to not be a stylistic choice, but rather his eye has literally turned into an X.
    • In a comedic example, when Soul Boyfriend chucks a guitar at Boyfriend during "Discharge", Boyfriend's right eye briefly turns into an X and a triangle before returning to normal. Boyfriend's right eye once again turns into an X during "MEMORY//LEAK", when Soul Boyfriend literally punches him out of his mindscape and back into conscious control of his body.
    • When Boyfriend pulls out the wrapped guitar during the Christmas special, his eyes turn into white stars.
  • World's Strongest Man: Alongside with being a One-Man Army, Daddy Dearest is the only character in the Corruption Mod to be capable of facing down an entire army of corrupted victims. Even when facing an entire infected army, he shows no signs of being rapidly corrupted and is actively resisting every attack that is thrown at him, except for Mommy Mearest's arrival.
  • You Are Not Alone: In times when Boyfriend is not feeling well on his goal to fight back the Corruption, he has Soul Boyfriend to cheer him on to carry on the fight.
    • At "Neuroses", Boyfriend is left completely alone to confront the Corruption, as Soul Boyfriend ends up disappearing in the end of the song. Not having Soul Boyfriend to support him, Boyfriend loses the will to fight and can only call on him to return. Luckily in "Discharge", Soul Boyfriend does return and this time, he gives Boyfriend a guitar to better combat the Corruption. The moment the Corruption tries to demotivate Boyfriend with lies, the latter's remembrance of his friends through a Precious Photo is what pushes him forward to overpower the Corruption.
    • By the first half of "Estrange", Boyfriend goes through a Sanity Slippage from Evil Girlfriend's illusions and nearly gives up trying to fight her. Fortunately, through Soul Boyfriend's silhouette appearance in the middle of the song, the latter is able to restore Boyfriend's confidence to fight forward. Afterwards, Boyfriend starts to overpower Evil Girlfriend and pushing her to become more desperate.
  • You Can't Thwart Stage One:
    • The Corruption begins its terror once it infects Boyfriend and Girlfriend to continue its spread. Pico acts as the first line of defense in attempt to stop the two, but fails trying to do so, as Pico winning would stop the entire Corruption story from ever happening.
    • Inverted. Once the Corruption succeeds in infecting everyone, the whole world is doomed, until Boyfriend is wakened by Soul Boyfriend. Despite the Corruption's attempts to overpower the two, they both end up breaking free from its grasps, leading to Boyfriend's journey to free everyone from the Corruption.
  • Your Soul Is Mine!: Boyfriend's battle between Evil Girlfriend and Evil Pico reveals sentences being written on the Corruption's main goal of wanting to harvest lots of souls.
  • Zerg Rush:
    • What gets Mommy Mearest overpowered by the Corruption is when her corrupted backup dancers surround the battlefield between her and Evil Pico. Being completely trapped by the corrupted victims, Mommy Mearest lacks the strength to keep up on her survival and to save Pico.
    • Daddy Dearest in "Deathmatch" is confronted by an huge horde of corrupted victims that appear in the background and is faced with having to sing along the corrupted FNF cast.

Boyfriend Glitches Out

Week 6 of the Corruption mod takes full advantage of the in-universe videogame setting, featuring a heavy use of glitching to hammer in how "other" Boyfriend and Girlfriend have become and how they do not at all belong.

How well does it match the trope?
