SoulTale

SoulTale is an UnderTale Soulmates AU (Alternate Universe) created by Karameru01. 
This AU takes place in a world where the war between Humans and Monsters never happened. Instead, the two nations thrived together on the Surface, due to a significant factor that binds them together, Soulmates. 
== General Information ==
=== Soulmates ===
Soulmates are the significant other that individuals are assigned to once they’ve become of age. In this AU, the age is eighteen. The Soulmate of a person is someone that makes the user feel whole, or complete. Their significant other allows them to feel empathy and emotions, as well as being able to boost their abilities.
Once a person becomes of age, it is highly recommended; mandatory even, for them to find and make a connection with their Soulmate. People are able to locate their significant other(s) by measuring how much they are capable of feeling; if they’re far from them, they can’t feel emotions, if they’re near them, they can. This feature is only useful in this occasion.
Physical and mental distance happen to play a part to how empathic a person can be. If a person is very far away from their Soulmate, their emotions are nulled and can sometimes be nullified to the point of being emotionless. This concept applies to bad connections as well. However, if a person is physically close and/or shares a good bond with their Soulmate, their emotions are heightened, and are capable of sensing feelings. 
Due to the SOULs of Soulmates are bounded together by fate, their emotions and feelings are intertwined with one another. This allows a pair—or group—of Soulmates to essentially feel what their significant other is feeling, and may also be able to know what they’re thinking of; if they’re skilled enough. 
People are capable of having more than one soulmate; this is known as being polyamorous, however, this chance is rare. The person is also incapable of gaining a new Soulmate, even if their initial Soulmate were to be deceased, or were not favored by the said person. 
Unfortunately, it’s possible for people to not even have a Soulmate. Without a Soulmate, a person will never be able to feel anything. If one is unable to be with, or make a connection with their Soulmate, they’ll turn into an emotionless husk, void of any love. 
=== Other Changes ===

** Asgore is a florist instead of a King.
== Main Characters ==
=== Sans ===
Sans is a monster with the physiology of a short skeleton. Unfortunately, he was born without a Soulmate, and, therefore, is incapable of feeling emotions for anyone or anything. He is usually seen wearing a flat expression. He’s the main character or protagonist SoulTale.
In this Universe, Sans is an apathetic, blunt, and lonely monster that often isolates himself away from his family and friends; he isn’t even consider them his friends or family, as he’s unable to feel love towards them. He occasionally speaks in a monotone voice. Due to not having a Soulmate, he’s unable to feel fear, sadness, or even hatred for anyone. He’s given up on life at this point, and just stands idly; lazily around since he doesn’t have any sadness to end it all. 
=== Papyrus ===
Papyrus is the younger brother of Sans, as well as being the Soulmate of Mettaton. He’s a tall monster with the structure of a geometric skeleton. He’s a helpful side-protagonist of SoulTale.
Papyrus is a bright, cheerful, and energetic skeleton that is commonly friendly around anyone he comes across. He’s very altruistic and kind, but is also quite eccentric to a fault. He enjoys spending time with Mettaton and likes to solve puzzles. 
Due to Papyrus not knowing about Sans not having a Soulmate; he still believes that it’s just Sans being tired and lazy as always, Papyrus will constantly try and have Sans hang out with him and his friends.
=== Undyne ===
Undyne is one of the deuteragonists of SoulTale, along with being the Soulmate of Alphys. She’s an aquatic monster with the physiology of fish-like creature. 
Like her original counterpart, Undyne is undyingly passionate and confident, along with being very emotional and steadfast. She’s known to be the “cool sister” figure that most children would want to have. While she may be very confident, she can sometimes be a little nervous and awkward around Alphys. She loves and appreciates the latter very much, and enjoys watching anime with them. She’s also the one that taught Papyrus how to cook.
=== Alphys ===
Alphys is a yellow, reptilian monster that happens to be one of the deuteragonists of SoulTale. She’s also the Soulmate of Undyne.
Alphys is an introverted, awkward, and recluse individual that has a significant fondness for humans and anime. In contrast to her Soulmate, Undyne, Alphys is quite the pushover, and is a victim of low-self esteem. While she’s incredibly insecure and shy, she can be very compassionate, loving, and sometimes excitable when it comes to talking about her favorite things; anime and Undone for example.
=== Toriel ===
Toriel is one of the side-protagonists in SoulTale, as well as being the wife of Asgore, and the mother of Chara and Asriel. She is a monster with the physiology of a goat. 
Toriel, like her original counterpart, is a motherly monster who loves children and puns. She happens to be very over-protective of Character and Asriel, but only wants them to be safe. She’s also a “friend” (If sans even considers her as one) and is the only one that is aware of Sans’s predicament. She occasionally tries to help Sans with his non-existent emotions by giving him a hobby; such as teaching him puns. 
=== Asgore ===
Asgore is the husband of Toriel and the father of Chara and Asriel, along with being a side-protagonist of SoulTale. He’s a bulky monster with the physiology of a goat. 
Similar to Toriel, Asgore is a kind, compassionate, and caring monster that enjoys gardening, along with being somewhat shy and quiet. He loves his family a lot, and enjoys spending time with all of them. He’s also a friend of Papyrus. 
== Trivia ==
* This AU was inspired by a comic dub made by TehRogue, (https://youtu.be/yV36MXK0-uM).
* The AU was originally named LoveSickTale (based on Google definition) but it was later changed to SoulTale instead. 
** SoulTale (In its’ past name) was named after Sans’s fate of not having a Soulmate; Sans is missing a Soulmate, but not out of love. He misses his Soulmate because he can’t feel without them. 
*** The meaning of the old name means: “in love, or missing the person one loves, so much that one is unable to act normally.” Which could be a reference to Sans’s apathy.
* This AU is not to be confused as a “Yandere Stereotypical” type of AU, because unlike a Yandere AU, there is no obsession or anything in this one. This is a normal, Soulmate AU.
