– Frisk to the armored guard
Xénotale is an Undertale AU created by Zeno Dreemurr on September 22, 2018 that shows the fear that monsters can have or give as well as any action has consequences. The AU is mainly shared by scriptural stories. Some Undertale events are rewritten by the creator, though the story is close to the Undertale one. It is an AU that also partially rewrites some aspects of the lore of Undertale, and adds its own lore, characters and locations into it.
Characters[]
Undertale Characters[]
Frisk[]
Main article: Frisk
Frisk is the 8th human to fall into the Underground. As soon as she fell, she began to hear a voice. She lost consciousness and wanted to scare all the monsters, and when she gets tired of scaring them or cannot, she kills them. In the pacifist route, she is controlled by Chara, and in a eidocide route, she wants to kill everybody to punish Chara, who controlled her in the pacifist route.
She is very arrogant and seem to always has been, and hates disobedience, often screaming at Chara or The Voice if they don't obey her, mostly asking them to don't talk or, to The Voice, to give her the solutions to the puzzles. However, she can also like people, as her love for Papyrus grows during her journey into Snowdin. She also is patient enough to fish until she gets something, and kind to vendors. She doesn't hide how much she likes Papyrus, and is frank when she speaks. Due to her new ability, she loves to use it and complains if she can't use it or if she hasn't used it for hours only, killing people in the first case. She tends to underestimate monsters, but recognizes when they are strong. She can be interested in stories that happen in the Underground. She accepts advice when people argues about them and follows them sometimes. She doesn't care about how the monsters fell, and mocks human and monsters for various reasons.
She looks like Classic!Frisk but she has no shorts. Her eyes are red with red outlines around them and are open. Her eidocide appearance is slightly different because she uses a bloody true axe.
In the current published material, Frisk fells in the Underground and meets Chara and The Voice. She traverses the Underground with them and plays a game where she scares monsters or kills them if she's unable to do so. She traverses the ruins, where she meets Toriel and kills her to escape it. She also goes through Snowdin, where Papyrus rules and eventually survives to his traps, kills the armored guard and becomes a great friend of Papyrus's. She also goes through Waterfall, where she kills Undyne, the captain of the royal guard. The difficult part for her is where she is in Hotland and dies to Alphys's trap multiple times, even if she has Gaster as an ally. Fearing the CORE, Gaster forces Frisk to fight Aster and she survives to the fight, going to the CORE. There, she falls in the oblivion prison but escapes and kills Mettaton. She ends up in New Home where she fights Asgore and Flowey to end up getting back the surface.. Her first appearance is in the first episode.
In Xéno!Papyrus's journey, she is killed by Papyrus while doing her eidocide. Not long after her death, she finds herself in the loading screen to continue and kill Papyrus. Though, Papyrus comes and the possibilities disappear. There, she fights Papyrus again and dies again.
She is the protagonist of Xéno!Frisk's arrival as well, in which she discovers the Multiverse after a neutral ending. In this story, she joins Zeno's organization in exchange of being freed from Chara. She then does missions under Zeno's orders with helps from The Voice and from Error404's minions.
Chara[]
Main article: Chara
Chara is the first human to fall into the Underground. She also had the determination and heard The Voice. Because of this, Asgore killed her several times but one day, she died without being able to use her determination to resurrect. Her soul was then destroyed by Asriel. Later, when Frisk fell, she resurrected in Frisk's mind with a ghost of her soul. In the pacifist route, she controls Frisk and make her do the pacifist route. In the eidocide route, she sacrifices herself -even if it's pointless- to try to keep Flowey alive. She knows and hates that The Voice made Frisk lost her mind.
Before she heard The Voice, she was jovial and happy with her family, but after she heard it for the first time, she became a bit crazy and scared of Asgore back then, she liked to go in the wishing room with Asriel. When she resurrected inside Frisk's mind, she began to have bad memories and, because of seeing Frisk half manipulated by The Voice, started to hate Frisk and be afraid of her. She also seems to enjoy the times Frisk dies and hates the scare act. Like Frisk, she wants to know how to solve the puzzles. Upon seeing lovers, she shows herself caring a lot about them and finds them cute. She dislikes narcissism, and since only Frisk and The Voice can hear her, she doesn't hesitate to tell them what she thinks. She sometimes congratulate Frisk for what she does, or even agree with her rarely.
She looks like Classic!Chara, but because of Asgore attacks in the past, she has scars everywhere on her body. At the end of the eidocide route, she has been gashed.
In the current published material, Chara meets Frisk and The Voice when the former fell. Though she is mostly a voice in his head, she is also a secondary character of a point of view, which describes what happens to Frisk when she can't, or when she has some private discussions with The Voice. During the story, she mainly criticizes Frisk for her actions, but learns the story of the Underground since her death, which is told during episode 49. When Frisk gets back to the surface, The Voice said she would be with Frisk forever. She eventually gets proposed by The Voice to control Frisk's body, and accepts, which allows her to Reset and start a pacifist run. Her first appearance is in the first episode.
She has a minor role in Xéno!Frisk's arrival, in which she is freed from Frisk's body and gets her own body back, only for Frisk to bring her in her bedroom. In the end, Zeno frees Chara from Frisk's bedroom and brings her in the Void of the specific timeline she is in, where she gets her own house.
Flowey[]
Main article: Flowey
One day, Alphys did experiments on the determination on the last golden flower of the Underground. Asgore thought injecting too much determination into this flower would make it melt like monsters. Instead, Flowey was born with the power of determination, but he heard The Voice and began to be afraid of them. He squatted at Alphys's lab in secret, but she found and turned him later. He sought asylum several times but in vain, so he tried to kill her, but she survived. He ended up being his main test subject, but during an experiment, everything went wrong. It turned out that humans too could only contain a limited amount of determination and Flowey absorbed more than that amount. He recovered his power to manipulate the save file but some of his parts melted anyway. He met Frisk soon after and lost his power again. He started to be afraid of her and then disappeared. During the neutral route, he spies Frisk, but after her fight against Asgore, he fights her, the fight having five phases. During the eidocide route, he's the last one killed by Frisk.
He's a flower who hates the power of the determination and The Voice. He is also afraid of them, Alphys and Frisk. He's nice with everybody except very rare times when he's naughty. He doesn't hesitate to fight if it's necessary and, so, fight Frisk in his normal form in the first phase of his fight.
Because of Alphys's experimentations with DT, some petals and one of his eyes melted. He's closer to the ground than Classic.
In the current published material, he is scared by Frisk since the beginning, but spies her during almost all of the neutral route. Though he mainly does that, he also helps monsters on situations related to her, such as Monster Kid or Gaster. At the end, he absorbs the six human souls to fight Frisk, and though they accept to help him, he fails against Frisk and Zeno. His first appearance is in the first episode.
He is killed by Celerity in Xénotale: Celerity so only the members of the organization are in the timeline.
Toriel[]
Main article: Toriel
Toriel was the former queen of the Underground and the mother of Asriel. During her reign, she welcomed Chara, who became a little crazy because of The Voice. Asgore started to kill Chara several times, and when Toriel discovered that, she divorced Asgore and took Asriel with her. Asriel died the next day.
Later in the ruins, she saw Flowey with the same symptoms as Chara. She inquired with Napstablook about this. She often spoke to Sans via the ruins door but one day she came out of the ruins and met him. From there, she began to come out of the ruins often to see Sans. But even later, she met Frisk and noticed that she scared everyone and wanted to stop her.
She wears a short dress with short sleeves and the delta rune symbol. Her eye is constantly burning. When she is angry or she is fighting she's completely on fire.
In the current published material, she receives and initiates Frisk normally, but when she understood Frisk had the same symptoms as Chara, she left her and sent Napstablook spy her. It's said in her diary that she thinks that Frisk is dangerous and said to Sans that he can use every method to stop Frisk, and that she doesn't mind if Frisk dies. She kills Frisk one time, but died on her second fight. Frisk also notices she can't be scared during the first fight against her. Her first appearance is in the second episode.

Napstablook[]
Main article: Napstablook
After Flowey arrived in the ruins, Toriel quickly noticed that he had the same symptoms as Chara in the past. She then asked Napstablook, who would be discreet, to spy Flowey and report back the information he got to her daily. He accepted. Since then he has been spying Flowey and reporting to Toriel every day. He can resign at any moment.
Since he works for Toriel he's in fire and he looks demoniac.

His only appearance is in the third episode.
Sans[]
Main article: Sans
Sans is a skeleton who lives with his brother and obeys to the strict rules of his brother. Because of one of them, he no longer drinks ketchup.

In the eidocide route, when he saw his brother -who was stronger than him- being killed by Frisk, he decided to train in order to defeat her. Zeno trained him. Though he died thousands of times during the training, Zeno revived him. Zeno eventually made him stronger after the training. Between the first and the second phase of the fight, an energy made it more powerful. Nevertheless, he ended up dying at once attack, doing infinite damage.
He is very afraid of his brother and of a part of the royal guard, however, he trusts Snowdin monsters. He tries to do a lot of things to kill his brother, like using people, but just wants to protect monsters from threats, but makes sure his plans go well. He dislikes being tortured and tries to save it from it, but accepts it when its unavoidable. However, he considers himself to have his priorities straight, and prefers to go warn Asgore and judge Frisk at the cost of being tortured more. To make sure Papyrus doesn't understand what he prepares, he helps him sometimes. He doesn't think Frisk can survive through Papyrus traps, but look at her in case she would. He shows to be way more afraid of Alphys than of Frisk, though the latter is a human that is far less predictable. He is good at analyzing, not hesitating to state that Frisk has done good, though he knows it was unintentional.
In the neutral and pacifist routes, he has the same appearance as Classic except his glowing eye only is yellow. In the second phase of his eidocide fight, a red energy envelopes him. He has a gash like the gash at the end of Classic!Sans's eidocide fight. In this phase his glowing eye is red.

In Xéno!Papyrus's journey, after Papyrus's disappearance, he takes Frisk's soul. When Papyrus comes back, he doesn't hesitate to confront himself to him, being confident thanks to the power of the human soul. However, during this fight, he ends up being killed by Papyrus.

He is a basic Snowdin inhabitant, but he doesn't understand many things, such as Papyrus's laws or the hate that monsters devote to Papyrus, who, as a royal guard, protects them. However, he hates the other royal guards, who torture him for Papyrus, who doesn't have the time. Even with that, he doesn't really understand what is happening. Monster Kid studies the story of the Underground, and when he encounters Frisk, who saves him from the royal guards, he follows her throughout the entire Waterfall arc. During this arc, he tells to Frisk the story of the royal guard. Frisk finds him annoying, say that he's pestering her but also say that what he's telling about is interesting, and Chara uses this information during the pacifist route.

Celerity asks him where Papyrus is, and Monster Kid answers that Papyrus has disappeared because he has something to do since Sans is dead.
Undyne[]
Many years after Asriel's death, Undyne became the head of the Royal Guard. Asgore told to her what he did et why he did all that, so, she discovered the power of the determination. However, she didn't know if she'll help him or sent him in jail. She decided that she'll decide about that when she'll have a human soul. After that, she encountered Zeno. She thought he was a human and fought him. She lost the fight, but didn't die. After that, Zeno became the threat of the Underground. She was afraid that he can try to ruin the plan to free the monsters from the Underground, so she began to recruit any monster that wanted to be. She also recruited Papyrus, who, because of his power, became the second of the royal guard. He wasn't as powerful as Undyne, but rally many royal guards to his causes, enough to dismiss Undyne from her role of head of the royal guard. Since that, she work on her side until she encounter Frisk.
She is afraid of Zeno and Papyrus, and is hesitating often about what his the right choice about Asgore. She is also feared about Papyrus becoming the head of the royal guards. She hates the power of the determination in bad hands. When Frisk fights her, she can't escape the fight, because the exit was blocked by Zeno. That means to spare her, she has to use the scare act.
In the current published material, she hunts Frisk down for being a human, while fighting the evil royal guards all along, because they try to kill her.

Alphys created Flowey in the past. Flowey was so scared of The Voice that he was squatting at Alphys's lab, but Alphys turned him constantly. When he wanted it to not happen again, he destroyed Alphys's soul. In order to survive, she then took pieces of the six human souls guarded by Asgore and quickly created an artificial soul with them, which gave her determination and its powers. She became obsessed because of these powers and of The Voice, but when she lost them, she wanted to find them and went crazy. She is constantly trying to trap Frisk using Mettaton or normal traps.
Alphys is a cruel person, wants absolutely to have the power of the determination, even if she has to kill many monsters for that. However, she can have a good side, still helping Mettaton for his shows, and can just show herself being passionated by science. She is also stated to be extremely strong, capable of killing Toriel or burn her laboratory in a single attack[1][2] and kill Papyrus in two attacks, due to her melange soul[1]
When Flowey attacked her, he drilled a hole in the middle of her body. After that, she replaced her past soul with a new soul. Her soul is a soul with a giant hole in the middle but with pieces of the six human souls guarded but Asgore turned towards the exterior. Because of her experimentations on determination, a part of her head has melted.
In the current published material, she doesn't do many things besides forcing Mettaton to get Frisk's human souls and helping him with his shows, but her traps kill Frisk a lot of times. She also runs the oblivion prison, where she brings every person who enters the CORE, including Frisk. That causes her to fight Gaster, who wants to free Frisk from it, though they both come back at her laboratory. She eventually returns to her laboratory, seeing the fight between Frisk and Mettaton, more worried about Phobos. Her first appearance is in the twenty-seventh episode.
In the seventh bonus, while she is fighting Gaster, she is interrupted by Phobos, who reveals his plans to her. That causes her to go back to her laboratory.
Gaster[]
Gaster went away from the void helped by Zeno. He then helped Alphys during his experiments as a scientist. One day, there was an accident and some determination melted a part of his skull. He helps Frisk pass Alphys's traps in the neutral and pacifist routes. However, Gaster merges with Sans after having fought and beaten Muffet, and fights Frisk afterwards. During the eidocide route, he seems absent, but before the Last Corridor, he fights Frisk, which can make her unlock the True Axe.
He looks like the Undertale Mystery Man but more solid. Because of Alphys's liquid determination tubes and a lack of attention, a part of his skull melted.
In the current published material, The Voice tells a written story about him. In this story, it is written that Gaster is the one who caused the war between the humans and the monsters by killing a human for one of his experiments. It is also written that he is the one who discovered how to destroy the barrier. A bit later, it is told that he has been thrown in a part of the CORE so he could die or be imprisoned, then that everything has been done so he could be forgotten. He appears later, as one of Alphys's helpers, though he decided to help Frisk to survive, by updating her phone but also by telling her how to survive to Alphys's traps, by training her to fight or by freeing her from the oblivion prison, which causes him to fight Alphys. Though she is strong, he survives and goes back to Alphys's lab with her. His first appearance is in the twenty-seventh episode.
In the seventh bonus, while he is fighting Alphys, he believes he can't beat her. However, Phobos interrupts their fight to reveals his plans to them.
Mettaton[]
Mettaton is a ghost inside of a robot body created by Alphys. In the past, both were good friends, even before the robot body had been created. Eventually, something happened and Alphys forced Mettaton to help her, at the point where he is considered by Gaster as "Alphys's slave".
Not much is known about how Mettaton was like before he was imprisoned in his robot body, but something sure is that he desperately wants freedom since then. Besides that, he still dreams to become a star, though he knows that it will be difficult. He gretaly considers what the spectators of his shows want, and wants to content them. Though he knows about the existence of timelines, he prefers that the spectators do not know about it, but likes to trick people into saying it, and even saying a lot of things for his shows.
Under his normal robot form, he looks like a box with two arms, two legs and two wheels for moving. His main color is yellow, which is caused by Alphys's electrical magic. Inside his body is also electrical magic from Alphys, invisible from outside. The main reason for that is to trap the ghost inside the body. His Mettaton EX 2.0 form is different. He is much more anthropomorphic, though is main color is still yellow. Under this form, as he sacrifices some part of the body to heal, he can be seen armless, or even armless and legless.
In the current published material, Alphys calls her to kill Frisk. However, his attacks are unefficient, so Gaster comes with the idea of letting Frisk go for a time. During the time he doesn't appear, he prepares his shows with Alphys's help, and Frisk goes through three of these before she goes to the CORE. When she fights him in the CORE, he uses his new update, the Mettaton 2.0 form, but he fails to get her soul. His first appearance is in the twenty-seventh episode.

He appears in Xénotale: Celerity, in which he is introduced during the Outertale meeting. He tries to help during the meeting, though he doesn't succeed like every other person in it. He reappears in the Doodle Sphere, hearing The Voice. Him and The Voice share the control of his body and words. He helps The Voice sending their message by lack of choice and begs to be authorized to leave the protectors. He eventually leaves, never to be seen again in Xénotale.
The Voice[]
Main article: The Voice
The Voice is the entity that follows and speaks to all beings that control the power of determination (in the order Chara, Flowey, Alphys, Flowey again and finally Frisk). They were created by Zeno and are under his command. They gave power Frisk and control to Chara, but in Frisk's case, she became more arrogant and insane than before, even though these gifts are not needed for The Voice to control Frisk and Chara. The Voice criticizes Frisk every time she decides to scare or kill a monster in the neutral route. They are also a herald for Zeno's minions because they tell them his orders. They are most likely impossible to kill.
Because of that, The Voice has no real personality. Their name is "The Voice" because they're just a voice, and they don't have a material form.
In the current published material, after giving power to Frisk, they help Frisk to understand how the underground work and give her the solution to some puzzles. They also say to Chara that they have a work that is "exhausting" and "exasperating". Within the Snowdin Arc, they show to Frisk and Chara that they have a lot of knowledge about the Underground. They explain to frisk what a dimensional box is, then advise her sometimes. They explain to Frisk and Chara what the Loading Screen is while they are in it, and, during the revenge against the armored guard, they tell Frisk to act like if she was surprised of some events she knew about. When Zeno is talking to Frisk, they don't say anything. They incite Frisk to go behind the Waterfall she finds weird. At one point, she tells Frisk and Chara the story about Gaster not only the first time the texts about it appear, but also the second time. After her fight against mad Dummy, they tell Frisk where she should go. The second time Zeno appears, they don't talk and apologizes about it again. Later, when Frisk returns to the Surface, they rarely talk until the moment they propose to Chara to control Frisk's body. They give Chara the control over Frisk's body when she accepts, and becomes active in Frisk's mind once again. Their first appearance is in the first episode.
They make a brief appearance in Xénotale: Celerity, where they make the Multiverse panic by talking with or controlling beings with determination, which make them become an enemy of the protectors. This event is stated by Zeno to be a diversion though.
In Xéno!Papyrus's journey, they control Papyrus to makes him use the "escape" possibility, then disappear. Opposite reveals that The Voice attacks people who have determination in the Multiverse. Not long afterwards, Papyrus tells Ink!Sans and Opposite!Sans what he knows about The Voice. In Zeno's HQ, Papyrus learns that The Voice is a member of Zeno's organization. Some time later, The Voice helps Papyrus to succeed in his mission.
In Xéno!Frisk's arrival, they just slightly help Xéno!Frisk.

In the eidocide timelines, the human kills the monsters for their own pleasure, doesn't show any form of empathy towards them, and has a violent behavior.

Basements of the Underground[]
Main article: Basements of the Underground

The basements of the Underground are where most of the dead monsters, turned into dust, are found. Frisk can also find some heal items like dog residues or false heal items like empty ketchup bottles or full ketchup bottles in this place. She can also find a room used as a torture chamber in these basements. This room is used by Papyrus in the neutral route to torture Sans if he's spared by Frisk.

Nobody can enter without having Zeno's permission beforehand.
The headquarters contain a main room that is the room people are when they enter in the headquarters first, a dining room and an informative room, where all of the members of the organization reunite to have explanations on their missions or on situations.

If someone is unauthorized to enter, the person can't see the bedroom. The owners of the bedroom can customize theirs.

- The Voice has stated that the fireproof knife should be more powerful than them, though it isn't the case, and that why it is like that wasn't discovered yet.
- The ballerine shoes are replaced by the fighting shoes. Those can be equiped while another weapon already is, and, after Frisk attacks with them, she can attack with the other weapon on the same turn.

- Frisk gets the real knife and the heart locket in the neutral route.
- A new type of attacks, yellow attacks are added. Instead of using them to attack normally, those who use it attack while the yellow attacks create very little projectiles that take the shape these have to attack the opponent of their user.

Trivia[]
- The Voice was inspired by Sky/The Virus from Freaktale.[4]
- Frisk is LOVE 22 at the end of the eidocide route.[2]
- Asriel has the equivalent of fourteen human souls during his fight in the pacifist route.[2]
- In her Undying form, Undyne isn't more powerful than her Undertale counterpart.
- One of Asgore's themes, Der Schlächter, means the killer in German.
- The title of the sixth arc of the neutral route of Xénotale references a character from another AU.[5]
- Like Undyne and Sans, Toriel, Papyrus, Monster Kid, Alphys, Gaster, Mettaton and Asgore have real fights during the eidocide route.
- According to the author, the idea comes from Freaktale.[4]
- Zeno comes from Undertale: The Ultimate Timeline, and his story was written in late 2017.
- Xénotale was taken over when the author wanted to redo an AU because he loved Freaktale. However, it's when one of his friends announced she'll publish her AU that he published Xénotale.
- The author of the AU created Celerity!Sans some weeks after having published Xénotale.
- The name of the AU went from the greek word ξένος (xenos), which means strange.
- The author hates when someone forgets the accent mark on the first "e" of Xénotale.
