An Anomaly in the Underground is a a crossover Fusion Fic of Iji and Undertale, taking the main character of the former game and putting her into the events of the latter. The fic was written by Zennistrad, who also wrote A Song of Silk and Saplings and My Little Planeswalker.After saving the world (or what's left of it) from the Komato Empire's planned Alpha Strike, Iji heads to the famous Lone Mountain, Mount Ebott, in hopes of using the peak as a vantage point for survivors. When taking shelter from the rain, she falls into the Underground — and what she finds there is stranger than anything she could have possibly expected.A sequel, titled Null Driver, takes place one year after the events of An Anomaly In The Underground and incorporates elements from Deltarune. As strange dreams of an alternate life continue to haunt Iji, a new darkness appears beneath Mount Ebott. Iji sets off investigate, only to be faced with a power that threatens to consume all of time and space.In addition to the above, there is also a series of Interquel one-shots, set on the surface after the events of An Anomaly in the Underground but before Null Driver, titled Alpha to Delta.

Virtual Soundtrack: Youtube links to various mood music are inserted throughout the fic. Much of it comes from Undertale and Iji, obviously, but there are occasional outliers.

The Worf Effect

comment
The Worf Effect: In Deltarune, Giga Queen is powerful enough that the heroes are only able to fight it on equal footing by summoning their own Humongous Mecha, and even then they still lose even when they win. Here, in one of the recurring dream sequences, we're able to see that Dess is strong enough to fight Giga Queen without a mech of her own and win.

Fan of the Past: Despite living in the twenty-second century, Iji knows weirdly a lot about twenty-first century popular culture. This includes recognizing the Show Within a Show Mew Mew Kissy Cutie on sight, and commenting on how bad the series is. Her Nanofield A.I., naturally, is the first to make fun of her for this.

Mythology Gag: One chapter features Momorin and Sue Sakamoto from Cave Story as cameo characters. Momorin being a botanist, and Sue having gotten in trouble for an unspecified "Spaghetti Incident", makes this a reference to one of the author's previous Undertale fics.

Crossover Relatives: An odd example, as while nobody from Iji is directly related to any characters in Undertale, a number of hints are given connecting Iji a character in Deltarune. Specifically, she's her own world's counterpart to Dess Holiday.

Accent Adaptation: An in-universe example. Vateilika has a noticable southern U.S. accent, even more so than in the original game. It's later explained that this was due to the English language training software assuming this was the equivalent to her own dialect of the Tasen language.

Asha is directly contrasted against Papyrus: both of them are glory seekers with notably inflated opinions of themselves who are nevertheless both able to back it up when the chips are down. The difference being, Papyrus is genuinely a Nice Guy who virtually everyone likes, and Asha is... the exact opposite of that.

comment
Upon seeing Iji in the True lab speaking to Chara and referring to them as her "best friend," Flowey immediately drops his usual sadistic attitude. When Iji sees him again, his mannerisms are uncharacteristically cold and measured, with none of the malicious gloating he's demonstrated up until that point. Once he appears as Asriel after absorbing everyone else's souls, he doesn't even bother transforming into his godly appearances at first, instead being ruthlessly dead-set on seeing Iji destroyed.

comment
Invincible Hero: Deconstructed — humans are already much, much stronger than monsters by default, but thanks to her nanofield Iji is so much stronger than monsters that she's practically a walking weapon of mass destruction to them. It takes a constant, conscious effort on her part to avoid killing people in the Underground by accident, and she's utterly terrified of herself as a result. That said, several monsters such as Sans as well as Papyrus and Mettaton's DELTA form are actually able to damage Iji through her nanofield, though it's made abundantly clear that monsters are not capable of this normally.

comment
At the end of Chapter 16, several voices appear in a Flashback belonging to an unknown trio of characters. While the voices are never identified, one of them briefly shouts "No—" before being cut off. Though out of context this sounds like someone shouting "no," it could just as easily have been someone shouting a name starts with the syllable "No."

The fight with Papyrus starts out with "Bonetrousle" as usual. When Papyrus stops holding back, the theme changes to "Big Boned Plus", the main boss theme of the expansion DLC to Skeleton Boomerang. The song is retitled "Live Alife," in reference to Megalovania being itself a Live A Live reference.

Boss Rush

comment
Iji plays an arcade game in Grillby's. She selects the hardest difficulty, "reallyjoel's dad," and quickly finds it unwinnable as it places her in a Boss Rush with every boss simultaneously, much like the "reallyjoel's dad" difficulty option in Hero Core. The exchange that follows also makes it a Continuity Nod to the unwinnable joke difficulty of the same name in Iji's own game.

The Riverperson, with their usual cryptic mutterings, mentions something about a girl named "Nobody" singing from somewhere called "The Darkness Beyond Time." When Noelle appears, she introduces herself as 'nobody.' Readers who are familiar with Chrono Cross may also know that the "Darkness Beyond Time" is a name for the Void Between the Worlds where events and people that are erased from reality end up.

comment
Adaptation Personality Change: Chara, as a Virtual Ghost in Iji's nanofield, noticeably has much more agency and presence than they do in the Neutral and Pacifist routes of Undertale. Eventually justified, as Chara later comments, by the fact that went Iji much more out of her way to them as an equal from the start. This resulted in them much more quickly regaining their own sense of self than they would have with Frisk as their host.

Spared by the Adaptation: As with many Undertale alternate universe stories, Asriel is eventually able to be saved by giving him a nanofield, which can function as an artificial monster soul.

Bait-and-Switch: Asgore, just before fighting Iji, realizes that it would be impossible to defeat her under his own power... and then comments that he will therefore not be fighting using his own power. For a moment, it looks like he's going to absorb the six human souls to fight Iji... until he instead summons a suit of Powered Armor, reverse-engineered from Komato technology by W.D. Gaster.

Wham Episode
 An Anomaly In The Underground (Fanfic) / int_8e20979
comment
Wham Episode: The CORE segment drops several very important revelations at once. the CORE is built with Komato technology, not monster technology, and is connected to a mysterious realm called 'Sector Z.' Sector Z is either a Dark World from Deltarune, or is otherwise somehow related to the Dark Worlds. Several logs within Sector Z make mention of the Null Driver, a reality warping Komato superweapon that was likely involved in Sector Z's creation. Then there's the fact that Noelle is in Sector Z and may or may not have become a higher being who created the entire universe.

Ret-Gone: W.D. Gaster was removed from reality to a seemingly even greater extent than in Undertale, as nobody seems to even remember he existed. Alphys notes several times that whenever she even thinks about the last Royal Scientist, her head ends up hurting. Noelle and the entire Deltarune universe are implied to have been removed from the timeline through some unknown means, though most likely involving the Null Driver.

Foreshadowing
 An Anomaly In The Underground (Fanfic) / int_9d12bbc1
comment
Foreshadowing: There are several early hints that point to the appearance of Noelle and the Deltarune universe in the CORE. Early in Snowdin, Iji asks Papyrus why he and his brother are named after fonts. Papyrus, being... Papyrus, misinterprets "font" to mean "fountain," then offhandedly mentions that his favorite fountains are made of dark chocolate. He then asks Sans if there are any monsters named after dark chocolate fountains. After meeting Gyftrot, Iji recalls a game she used to play with her family during Christmas, called 'pin the nose on Rudolph.' Her imagination then immediately jumps to 'a family of reindeer-people' in the vein of the Underground's Funny Animal population. Instead of Christmas, residents of Snowdin town celebrate a generic winter holiday called Holiday. Among these Holiday traditions is a decorative angel figure called... the Holiday Angel. Guess what Noelle's last name is. At the end of Chapter 16, several voices appear in a Flashback belonging to an unknown trio of characters. While the voices are never identified, one of them briefly shouts "No—" before being cut off. Though out of context this sounds like someone shouting "no," it could just as easily have been someone shouting a name starts with the syllable "No." The very next chapter, Gerson details a Creation Myth about an Angel that shaped the universe from primordial darkness. When Noelle finally appears, she's a seemingly ageless being with a very angel-like appearance. The Riverperson, with their usual cryptic mutterings, mentions something about a girl named "Nobody" singing from somewhere called "The Darkness Beyond Time." When Noelle appears, she introduces herself as 'nobody.' Readers who are familiar with Chrono Cross may also know that the "Darkness Beyond Time" is a name for the Void Between the Worlds where events and people that are erased from reality end up. The CORE being made from Komato technology is also hinted at prior to its reveal. Iji's Nanofield A.I. mentions offhandedly that Sans and Papyrus use magic with very similar properties to Komato nanotechnology, which is why said magic is able to hurt her through her nanofield. Given Sans's implied connection to W.D. Gaster in Undertale, this is the first hint that Gaster was doing something with nanofield technology. When Iji is traversing Hotland, she sees the CORE in the distance and notes that its "bright green exterior" and "very blocky and intricately mechanical design" are... something, and increasingly notes how familiar it looks every time she sees it. Observant readers who've played through Undertale might realize that the CORE's exterior in the original game was not green. However, Komato starships very much are. When observing Iji's nanofield through her cameras' Soul Scanner function, Alphys notes that it's fused with Iji's soul in a way very similar to how a Boss Monster soul would theoretically look after being absorbed by a human. This comparison turns out to be entirely apt, when she learns that a nanofield is actually an artificial monster soul. During his Quiz Show, when Mettaton asks what the name of the previous Royal Scientist was, one of the answers is "Dr. Varsilon." This name doesn't seem to be important, especially compared to the very noticeable "[DATA EXPUNGED]" option that hints at W.D. Gaster, until Sector Z's logbooks reveal that Varsilon was the head of Komato Imperial Research, and was responsible for creating the original Null Driver.

My God, What Have I Done?
 An Anomaly In The Underground (Fanfic) / int_a1b141f4
comment
My God, What Have I Done?: Iji has a minor one after being startled by a Froggit and killing it in a single shotgun blast, realizing just how effortless it was, and then learning not long after that Froggits are fully sapient individuals. Unlike the Tasen and the Komato, Iji quickly puts together that most monsters are not even remotely a threat to her, and that any act of "self-defense" against them could never be anything but murder. After Iji accidentally kills Toriel, the sheer grief and anguish causes her to trigger her first reset, without even realizing it at first.

Or Was It a Dream?: It's unclear just how "real" the dreams that Iji has of the Deltarune world are, but the lines between them are increasingly blurred when "Violet Hearn" (who is clearly Yukari Yakumo) seems to forcibly drag Iji into her alternate dream world as Dess, explicitly referring to Iji and Dess as one and the same.

Idiosyncratic Episode Naming
 An Anomaly In The Underground (Fanfic) / int_ac4ac8e5
comment
Idiosyncratic Episode Naming: With the exception of the prologue and epilogue chapters, all chapters of each Act are named after a song from a single indie game's OST. The chapters that end each act have compound titles consisting of two songs, seperated by a slash. The exception is the end chapter of Act 6, which uses a song that already has a two-part name. Act 1, the Ruins, has chapters named after songs from the Iji OST. Act 2/Snowdin has chapters named after the Shovel Knight OST. Act 3, Waterfall, uses the Hollow Knight OST for its chapter titles. Act 4, which covers the first half of Hotland, uses song titles from the Cave Story OST. Act Δ4, the CORE and Sector Z, uses song titles from Deltarune Chapter 2. Act 5, New Home, names its chapters after the Everhood OST. Act 6, which covers both post-pacifist and the True Lab, has chapters named after the Yume Nikki OST. Uniquely, the chapter titles in Act 6 are all in the untranslated Japanese. Act 7, the True Pacifist ending, uses songs from the Undertale OST. The final chapter, not counting the epilogue, is fittingly titled "Hopes and Dreams / SAVE the World."

Sheathe Your Sword: Toriel, assuming Iji is a soldier in a potentially genocidal human campaign against monsters, tries to forcibly stop her from exiting the Ruins. Iji learns the hard way after killing Toriel and resetting that trying to subdue her through violent means won't work. The eventual solution she finds is simply to drop her weapon.

Toriel, normally kind and doting to a fault, freaks out when she sees Iji is both an adult and carrying a lethal weapon, instantly jumping to the conclusion that Iji is a soldier who has come to finish what humans started against monsters thousands of years ago. She spends the entirety of Iji's journey through the Ruins running away from her, and when finally confronted threatens to kill Iji just to stop her from threatening the rest of the Underground's population. During Iji's second, post-reset run through the Ruins, we can see that Toriel is so spooked that she's considering leaving the Ruins to warn Asgore.

Shout-Out
 An Anomaly In The Underground (Fanfic) / int_c75df49a
comment
Shout-Out: Every character's Dark World outfit thus far resembles a character from another franchise: Dess's Dark World outfit is based mostly on Aqua, with some additional inspiration from Lady Iceheart. As in An Anomaly in the Underground, Iji's outfit is based on Adwoa of MURI. Asriel's Dark World outfit is based on the traditional White Mage garb of Final Fantasy, but with the red and white colors reversed. Chara's Dark World outfit is taken directly from the Blue Mage of Final Fantasy V.

Mirror Self: In one chapter, Alphys works together with a calm, soft-spoken human scientist named Nodens, and her extremely muscular, confident, and simile-speaking Large Ham girlfriend Gamra. The two are rounded out by Calibri, a jaded, cynical, heavily Brooklyn-accented man who carries skull-themed ballpoint pen. The three are effectively opposites to Undyne, Alphys, and Papyrus, respectively.

Battle Theme Music
 An Anomaly In The Underground (Fanfic) / int_e08fcc99
comment
Battle Theme Music: Most of Iji's fights with major Undertale characters have those characters' signature battle theme playing (see Virtual Soundtrack below). However, there are exceptions. Iji's first fight with Toriel which ends with Toriel's death, followed by an accidental reset plays "Mother Knows Best", a fan-made remix of "Heartache" by Moonster, for a hypothetical fight against Toriel in a Genocide Run. The track is renamed "Last Stand" in the music indicator, pointing at Toriel very wrongfully assuming that Iji is a soldier come to finish the genocide that humans started against monsters six thousand years ago. The second fight with Toriel, where she is on much friendlier terms with Iji, has "Heartache" as usual. Iji's fight with Sans plays "Megalovania," as one might expect. When she finally manages to turn the tables, the music changes to iFlicky's remix of "Last Battle" from Cave Story, retitled "Kill Me/Kill You". The fight with Papyrus starts out with "Bonetrousle" as usual. When Papyrus stops holding back, the theme changes to "Big Boned Plus", the main boss theme of the expansion DLC to Skeleton Boomerang. The song is retitled "Live Alife," in reference to Megalovania being itself a Live A Live reference. Notably, Iji's fight against Undyne doesn't have "Spear of Justice" as the battle theme, instead playing "Seven Four" from the Iji soundtrack. Even more notably, this is the only song with a green music indicator, exactly the same green as Iji's shirt. The implication is that the song is Iji's battle theme music, not Undyne's. When Iji encounters a Komato Sentinel Proxima in the CORE, the theme that plays during her fight is "Critical Juncture", the main boss theme of Cosmic Star Heroine. Iji's fight against Mettaton DELTA has a remix of Power of NEO, also by Moonster. This time, it's renamed "HENSHIN!! Power of Change, DELTA!!!" Iji's fight against Asgore doesn't have the song of the same name as the battle theme music. Instead, the theme for the fight against Asgore is "Tor" The first phase of the fight against Asriel uses Reconciliation from Everhood. It isn't until Iji gets her Heroic Second Wind that "Hopes and Dreams" starts playing.

comment
Undyne directly contrasts how Iji sees herself. Like Undyne, Iji is a highly skilled martial artist and an extreme Determinator, and both of them are noted for playing the piano. However, their attitudes towards fighting and killing are almost diametrically opposite. Undyne is almost unshakably confident in her own abilities (until she suddenly isn't), will stop at nothing to kill Iji, and will twist herself in knots to convince herself that this is the right thing to do. Meanwhile, Iji is terrified of her own strength and has to try as hard as she can not to kill anyone in the Underground, knowing full well that she would never be able justify it to herself if she did.

O.O.C. Is Serious Business
 An Anomaly In The Underground (Fanfic) / int_e83f211c
comment
O.O.C. Is Serious Business: Iji's terrifying raw strength means that a few characters react very differently to her than to an ordinary human child. Toriel, normally kind and doting to a fault, freaks out when she sees Iji is both an adult and carrying a lethal weapon, instantly jumping to the conclusion that Iji is a soldier who has come to finish what humans started against monsters thousands of years ago. She spends the entirety of Iji's journey through the Ruins running away from her, and when finally confronted threatens to kill Iji just to stop her from threatening the rest of the Underground's population. During Iji's second, post-reset run through the Ruins, we can see that Toriel is so spooked that she's considering leaving the Ruins to warn Asgore. In his original game, Sans doesn't bother trying to stop the player-character until they start going out of their way end the entire world, seeing it as pointless otherwise since that the timeline can just reset anyway. Here, he immediately tries to kill Iji as soon as she exits the Ruins, hammering home the fact that Iji is that much more dangerous than any other human that's ever lived. Several other characters, as well as Sans himself, note that he's not normally one to be that motivated. After suffering an absolutely humiliating but non-lethal defeat at Iji's hands, Undyne breaks down sobbing when she realizes just how powerless she is, and retreats to her house to quietly sulk. Papyrus takes notice of Undyne's sudden depression, noting that she's "much less shouty than usual." Upon seeing Iji in the True lab speaking to Chara and referring to them as her "best friend," Flowey immediately drops his usual sadistic attitude. When Iji sees him again, his mannerisms are uncharacteristically cold and measured, with none of the malicious gloating he's demonstrated up until that point. Once he appears as Asriel after absorbing everyone else's souls, he doesn't even bother transforming into his godly appearances at first, instead being ruthlessly dead-set on seeing Iji destroyed.

Running Gag: Iji's Nanofield A.I. saying "data not found" whenever asked to explain how they know something they logically shouldn't, typically something that hints at them having been Chara in a past life. Iji gets one herself after emerging from Sector Z, and Alphys asks her just what the hell happened. Iji getting pranked by Sans, and then immediately reloading a save in order to avoid it.

Instead of Christmas, residents of Snowdin town celebrate a generic winter holiday called Holiday. Among these Holiday traditions is a decorative angel figure called... the Holiday Angel. Guess what Noelle's last name is.

Death Seeker: It's very strongly implied that Toriel is this, when she challenges Iji to kill her and take her soul. It becomes clear later on that she blames herself for the deaths of the six human children.
