Hello this is my au it’s name undercharge
in this au at the beginning it started as how undertale backstory started until the war began ( with some differences like in the war their were some humans were killed bc of some monsters began fighting together but still the monsters lost the wars and most of them were frightened also sans and gaster relationship is friends ( so please I don’t want to see anyone saying gaster is sans father or his creator in this au also sans is as old as asgore and toriel so yes he fought along side gerson and gaster am gonna mention here that in this au papyrus is gaster brother who later after the accident has been adopted by sans as his new brother
Continuing the story of undercharge it’s all hardly stayed the same until Chara died bc after this incident the humans took it far to torture asriel infront of the monster kind ( asriel never defended himself bc he thought these humans could change until they killed him but his dust went to the underground ( they tortured him in the place frisk has fallen in not inside the barrier )) after asriel died the humans threw a lot of flammable objects and send on fire just to torture the monsters after this the humans continued laughing on the monsters not knowing the explosion they did would make them fall inside the Barrier and so these humans got into the mercy of asgore and toriel and weren’t affected by these flames and the humans got tortured until they died ( one was being killed by drowning other was being killed by asgore flames one was being cut in half and one is still alive but all of his limps is cut and he is only a head that lives in hotland to be a message so after this the second soul( the fallen human after Chara)has fallen into the underground asgore in a huge rage and anger killed the human and realized that as the new generation goes the monsters will grow softer and less ready if the human began a new war so he made a new rule that makes monsters kill each other to gather more lv and to be more ready mentally and physically for a new war against the humans the same happened toriel ran to the ruins ( in this au monster kill each other every 3 years to be stronger also when the main protagonist fall monsters were at 10lv also their were more fallen humans than the fallen humans in undertale bc asgore has been sicken at some point and sans alphys and some other scientist used the human souls to cure asgore at the same time some monsters tried to kill asgore while he was sickened but sans gerson and some other monsters who understood asgore decisions defended him and good for asgore they succeeded on curing and defending him until he retained his heath after this there was a explosion happened in the lab caused the monsters to be more dangerous and stronger than they were also monsters are evil and some suffer from some mental problems like as example papyrus suffer from DID(dissociative identity disorder) and undyne ( trauma)
am gonna explain some things about the characters here
Sans : right now is a mad illegal scientist after the new rule the job of royal scientist has slowly began to fade until the day asgore has been sickened( maybe poisoned) after that the job of royal scientist is just no longer a thing and sans began to do his experiment in his lab under his house also with his lv rising he slowly don’t feel regret ( not that he actually feels regret or remorse) with that in mind sans has killed multiple monsters at the same time experiment on some monsters after a year he had the idea of papyrus (7year old) is to good for this world so he thought he needed to step in and take care of that so he experimented on papyrus for 6years when papyrus became 13year old he planted to flee and leave this place he continued to fail bc sans before any experiment he beat papyrus to the point papyrus will only be able to hear and be so exhausted so papyrus won’t be able to fight back with that in mind 20 times papyrus trying to flee has been only successful failed until the 21 where sans has been distracted by a random monster who sans killed for absolutely no reason and at that moment papyrus has successfully got away and while he was running as far as possible papyrus stayed with undyne bc the two has suffered so much at a young age sans continued his experiment on multiple monsters and even child monsters from these experiments he actually gained so much abilities and so much magic that he became almost have infinite magic also he gained the power to keep his memory from the reset from these experiments he did on monsters children he always after experiments is successful he kills that monster he experimented on so they could not run away or even have the thought of leaving ( am gonna say what he got from these experiments later )
Undyne: her story she was abused by her father and mother mentally and physically sometimes her father attacks her mercilessly she lost her eye bc of her father after 10y she killed her father and mother infront of the king ( she planed to kill them but she didn’t expect it would be infront of the king) the king got impressed by how smart fast and strong she is bc she killed her father who was the previous royal guard ( she sneaked on him without even the king noticing) after this asgore took her and made her his own weapon a living weapon unstoppable killing machine still obtaining her job in the head of royal guards and trained under asgore hand etc but she is more aggressive and more heartless then any version of her also she likes villains more then heroes she act as the big sister to papyrus (in this au undyne don’t remember meeting alphys) she still got the dt from the dt experiment she can control her dt so much that her base is actually her undying form ( she has another form that is much stronger than her undying form but she still isn’t capable of mastering it but her dt in that form could almost overwhelm the protagonist dt )
Papyrus: he is the second hand of undyne they are like a brother and sister relationship also he returned to Snowden after 5 years to get his revenge on his torture the revenge ended in sans gained the advantage in experience and strength (bc of lv )papyrus has taken 5months of being tortured until he ran away again ( papyrus right hand has been cut bc of the torture sans did to him but don’t worry papyrus gained a mechanical arm instead of it (that mechanical arm can shoot beams also it can charge and if it’s charged 100% it does high damage it can destroy a village if it was 25% charged))he then tried to train and did something he wouldn’t forgive himself for and then after 10 years he returned to get his revenge unlike the first time in this time sans and papyrus were equals in everything this time they ended up injuring each other to the point they made a hole in each other chest and lost consciousness for 5minutes in high places (I almost said everything about him in me explaining sans sorry) but am gonna explain something about papyrus in this au papyrus have multiple personalities ( atk papyrus (marco) def papyrus (Steven) og papyrus (papyrus))
Papyrus: he is unaware of his different personalities he is a little kind close to his og papyrus but more aware of when he needs to be nice and when he doesn’t need to be
Marco: he is a heartless guy with no feel of remorse
He killed multiple monsters and was closest from his other personalities to defeat undyne also he killed monster kid bc he felt bored
Steven: he is the one who defend himself from any attack he got a compliment from undyne and asgore
Alphys: is hiding in the true lab so she won’t die from the other monsters and because even if she could fight she wouldn’t be able to get herself to kill anyone ( she still tries to create something you will know in another time)
Gaster : is a friend of sans and papyrus elder brother sadly he can’t do anything but see papyrus being experimented on by his best friend he is the one who made the explosion ( it was a failed experiment)
Asgore : he is the king of all monsters and the strongest monster in the underground and with most highest lv in them all also after asgore got sickened the Royal scientist used 4 human souls to cure him hoping he will wake up and understand his mistakes but unfortunately he only got stronger and more prideful and the monsters only lived worse after this decision and mostly the royal scientist who most of them died bc of the royal scientist are no longer a job and bc of it they are no longer protected from the other monsters asgore is the type of guy who don’t take any bullshit and is ready to sacrifice anything to get his revenge upon the humans also he loves to stay around his kingdom bc it’s help him calm down ( asgore is always being attacked by other monsters bc of his new rule ) but it’s always ends up bad for them also he loves torture the monsters who tries to attack him he hardly have a piece in his castle bc monsters on daily tries to kill him for his new rule also his ego also bc of things he did to them from making monsters kill each other to make them kill their own families and even sometimes kill their children the reason behind his anger and wrath is bc he lost the first war and that’s hurt his pride and the second is the humans torturing his son infront of him while he was powerless
Toriel: am just gonna say she just lost her mind after seeing her son dying infront of her also she happily tortured those who killed her son but not the others who had nothing with her son death and that’s why she left she never wanted to see her husband turn into something evil toriel is an evil mother and more like her horrortale version also she is kinda manipulative at the same time she suffers a lot by her guilt and remorse of killing other monsters and humans in her encounter instead of her helping you she tries to kill you ending up you run away from her in the ruins until you are close to the door which allows you to go outside of the ruins depending on which route you’re in your choice will change pacifist she will kill you before you even have the chance to mercy her also makes you return to the beginning of the ruins in the natural route in it you leave the ruins before she gets the chance to kill you in the genocide route you kill her when she thinks she killed you then you do a surprise attack it takes like 12death to kill her
Gerson : will am just gonna say he just couldn’t bear with it and decided to take the easiest way out :(
Funfact : all monsters has killed multiple humans but they crush those humans souls just because they want to disrespect those humans souls and
Monsters and their lv
Asgore:15lv
Sans:10lv
Papyrus:10lv

Mettaton:10lv
Most other monsters are 6-10lv
The routes
Pacifist route :
It’s just impossible- the main protagonists
They hardly made it out of the ruins and can’t make the monsters think of sparing them so the pacifist is just impossible
Natrual route:
It’s stop after Snowden as the choice u make would make a lot of differences between each natural route and another there’s infinite possibilities of it
Genocide route :
It goes so different than how it happens in undertale only with some similarities monsters is so hard to kill with their high lv and stats while at the same time they are more experienced and capable of doing so much damage in so little time making it harder to fight them also most of them have developed their own strategies in fighting and bc of monster kid has been killed by papyrus so the reason why undyne goes to her undieing form is bc of wanting to revenge her brother and monsters have more phases like toriel have 2 phases first plays as her fighting with her intentions to kill in most painful way she could also her fight keeps getting harder and harder until you get to half her health where her second phase begins by her surrounding herself by her flames creating an immune big avatar that makes any attack gets close/ in it melt until it’s disappear toriel can stay in this form for like 5 days ( without fighting or melting attacks) but with fighting and melting attacks she can stay in this form for like 20hour to kill toriel you need to overwhelm toriel by attacking unstopping to make her lose her magic faster after you kill her you got 10lv after killing toriel , papyrus have 3phases every personality of him have it’s own phase and it change how long his phases is taking , sans he have like 3 phases the first plays of harder then but close to any hard mode sans fight after damaging him enough he goes to his second phase where the main protagonist cut his arms and part of his head then he began to used some new tricks and attack he gotten it from the experiments like giant bone arms and laser from his mouth and some other attacks and undyne have 2 phases first is her without her undieing form bc of the lv and high stats it takes more than 4 hits to turn her to her undieing form (ur lv is 34lv) after she turns to her undieing form (phase2) also her attack change every time you die and mettaton have 1phase but it’s super long
After ten genocides routes
Then the redemption route is unlocked where all monsters began to remember all the resets and then ( until u go to the judgment hall the it’s just like any genocide only the monsters become more aggressive and they take more time to be killed and you don’t fight toriel papyrus and undyne) after you get to the judgment hall you then see a small goat who you realize he absorbed a human soul (light blue soul)
After you get him to low hp and it’s just the last it appears that ur attack just has been blocked by asgore then you got attacked by toriel flames and sans shooting at u with his gaster blaster and then got attacked by papyrus slapping the shit out of the main protagonist to then undyne throw her spears at you then the hell gate has been opened to get your soul
After 35 death each of them is more painful than the one before it
You called for help and human souls has answered your call just for the monsters to absorb the human souls and then you realized that monsters has made an injection that makes the humans unable to take control of the monsters while being absorbed
After this each of the these monsters has obtained a specific soul
Papyrus absorbed the kindness soul
Asgore absorbed the bravery soul
Sans absorbed the soul purple soul
Toriel absorbed the soul of dark blue
Undyne used the dt and absorbed the soul of justic
After another 50 death
You have heard a sound of someone using the dt star then you realize it’s the first fallen human and they don’t seem happy to see you
Chara became more look like freak then a human
After being killed 5 times
they decided to kill you once and for all which they ultimately managed to do it after that the survival monsters began to party and they killed another 7 humans and stayed in the underground so monsters would have the time to fix their mistakes still they aren’t that good bc if they could do it again they would with no hesitation but still they have forgiven each other and then they have broken the barrier also am gonna mention monsters each monster have 4souls in the end of this route
Asriel: have a mechanical soul which was powered by light blue soul
Chara: in this route have a mechanical soul which was made by alphys and that mechanical soul have a dt experiment
————————————————————————
Not a route that is main in the undercharge canon timeline but it’s still their and still achievable
Sinful sin route
In this route sans just want to try something new so he killed everyone and absorbed the human souls and then he began traveling in the aus until he got face to face with error404 404 though maybe this skeleton be a potential threat so 404 decided to take things into his own hands in the end 404 killed undercharge sans ( or that what he thought bc undercharge outsmarted 404 to make undercharge go to his fatal error form) after that incident sans got revived as he died in the save causing him to go to his fatal form then fatal undercharge sans decided to take his revenge on 404 which was successfully done unknowingly fatal undercharge is now in an infinite loop of him killing 404 and being killed by an unknown creature
Biggest sin
In this route papyrus has just had enough of monsters bs and decided to just kill everyone in his way after achieving his goals and got the 7 human souls he got his consequences after a while being stuck in the anti void he became his error version
False king route
In this route asgore decided to just get away of his mistakes causing him killing everyone in the underground and absorbing the human souls and killing all humans
False queen route
In this route toriel decided to just lose it all and killing everyone in the ruins and move on to kill everyone in the underground and after killing asgore and absorbed the human souls she just trys to justify her actions to herself which causes her lose what is left of her sanity and move on to kill every human monster or anything move
The rise of the villain route
In this route undyne decided to avenge papyrus which causing her to have more lv which makes her lose her sanity which causes her killing everyone in Snowden after that she no longer knows who is with her or against her so she just killed them all
There is like infinite timelines with infinite possibilities
