Threat Teir: High 5-A
Regretful Dust (Otherwise known as RT!Dust!Sans or The Regretful Murderer) is a version of Murder!Sans who beat his Frisk/Chara in the fight in the corridor but was not able to reset and traveled to other AU’s killing other Dusts/Murder’s and their Humans before finally settling down in a Undertale pacifist timeline acting as an unseen guardian angel for that timelines Frisk, Papyrus and Sans.
Backstory[]
(Warning: this backstory is VERY long but also VERY fleshed out, it’s a lot like a mini story)(Note from a Sansfan1563 who is 1 year older then when this page was made: This Warning made by an absolute Buffon aged like milk, but I will not remove it but instead commentate like this as I find it to be more funny.)
255 Genocides routes have passed, and just like the rest of them sans was struck down in the corridor. But this time something changed, right as sans was struck down he remembered EVERYTHING. All the genocides routes, all the times he tried to face the human and failed, all the times papyrus died. His mind could not handle the overflow of guilt negativity and regret breaking. Then Sans woke up in his bed at snowdin and decided why not fight fire with fire? Sans Went too his closet and got out a metal bat half the size of him and teleported into the ruins to start his OWN genocide route.
Unlike the Canon Dusttale Sans, this Genocide was much more thorough leaving only 1-5 monsters per area in the underground leaving his Frisk/Chara to have to scrape by and be even more thorough than him. Then Sans reached his encounter with papyrus, from one look at Sans Papyrus knew everything (kinda hard not too as he was covered in blood and dust along with his bat) Papyrus first tried to reason with sans and when that did not work, he ran into waterfall to escape him. Sans followed killing monsters while doing so allowing Papyrus to reach Undyne and together they decided to confront Sans and stop his massacre. When Sans found them Undyne yelled at Sans asking him to explain why he was doing this. Sans responded about what he learned about everything that had happened and how it would be better if he killed them instead of the human and once he got their soul reset the world like nothing had happened, Both Papyrus and Undyne did not like this idea. They got into a fight and 8 rounds in Sans caught Papyrus off guard decapitating him with a clean swing to the head with his bat, Papyrus said a few words before believing Sans could change, after that Sans went down to his knees and starting laughing manically and took a piece of Papyrus’ soul right after it shattered and stored it in a mini soul container he pulled out of his pocket to stop it from breaking completely stating that they would beat the human together and put the mini soul container back in his pocket. Seeing this reaction and action from Sans made Undyne freeze in fear and when Sans got up and was about to swing at her a knife fly by his head and into Undynes chest killing her instantly. The human had caught up and stole sans’ kill. Seeing this made Sans pretty mad and the first encounter with sans began, this fight was a lot harder for Frisk/Chara as they where only LV5 from how little EXP Sans left them while sans was LV9 and was attacking like a madman. 10 rounds had passed in the fight and Sans was struck with a ballet shoe and Sans made one final big attack and then fled killing more monsters while he went towards hotlands.
As you would expect Sans went straight towards Alphys and entered the true lab where Alphys tried to use the DT Extractor on him, Sans responded by throwing his bat straight into Alphys’ head killing her instantly. Then Sans got a bright idea, why not use the DT extractor to extract the DT from the amalgamates in order to get MORE DT, so he did just that, he then exited the lab and encountered Frisk/Chara yet again. Another fight ensues, Sans gets struck and flees while killing other monsters. From here the events in canon dusttale take place up until the corridor fight. Sans was MUCH more prepared being LV15 and much more determined then Frisk/Chara who was still stuck at LV5 after being starved of EXP. This time sans went full on psycho, fire engulfed the corridor, blasters, bones, Lasers, Pellets, Tridents flew around so fast it was hard to watch. Frisk/Chara died a total of 665 times, Frisk’s Will was broken they learned their lesson and wanted too reset while Chara wanted to kill Sans real bad. Chara attempted the fight one more time and made it too Sans’ final attack only too get crushed by his bat when she tried to get up close and personal, Chara gave up and Sans absorbed the soul. Sans was ecstatic he finally won and now he could res- *Error Filename:Reset is not responding* the reset button was not working, everything Sans had done, all the pain he caused, how he killed his closest friends, all of that for his plan to fail in the most unexpected way possible. Sans went to snowdin which was devoid of life and went to his secret laboratory and sat down. He thought and thunk to himself about everything and regret filled him, he wanted to go back but he could not, for once during this timeline Sans cried when he heard a voice, an oh so familiar voice.
Sans looked up and saw a specter of Frisk, Sans quickly looked down in disgust but Frisk kept on trying to talk with Sans until Sans could do nothing but hear her out. Frisk showed regret for their and charas actions and wanted to try and make things right, pointing towards the machine, the broken and useless one. But what else was Sans able to do, he could not just sit around a mope so he tried fixing it and over a month of hard work and advice from Frisk they got the machine too work and they where suddenly transported out of their timeline and into a new AU. Frisk even though not having a body felt something strange occur to their and Sans’ soul and when looking deeper found out they gained a new power, the power to jump between AU’s, Timelines, and FUN Values. They then traveled into the door room with snowdin when Sans heard another voice arguing with Frisk’s Specter who was behind him, Sans turned around and Chara’s Specter was their arguing with Frisk on why they would help their captor and murderer whole Frisk was arguing back with statements on what both of them did to Sans and why they should atone for their actions. As they argued for hours Sans noticed something, the mini soul container he had in his pocket was glowing and twitching until suddenly a burst of magic energy followed by a VERY familiar voice telling both Frisk and Chara to stop came from the container and an image of a very annoyed looking Papyrus appeared, the image was still and then changed to a lecturing pose telling both of them that everyone in this room (except himself) did some very bad things and that he should be very mad at them for this, but instead he chose to believe and still does believe that they can change and become better people. The image then changed again to happy looking Papyrus with his arms outstretched saying that fighting would get them nowhere and they need to work together to make things right. The room went silent until Sans decided on a new goal and jumped to another AU, a DUST AU. Frisks Specter then asked what Sans was doing with Sans quickly responding that he was gonna stop others from making the same mistake as him, through any means necessary.
Sans entered a familiar corridor colored red to which Dustfell Sans entered looking very confused and then a very sudden Metal bat to the face with Sans saying again "through any means necessary" as he shifted his hood up and his MAD TIME eye started to glow. Sans had made his intentions clear, he was gonna kill or stop other versions of him that do a similar thing to what he did along with the human of the AU he was in. The Quartet jumped from AU to AU with Sans at first doing all the work, then Frisk started to help by either shielding sans with a Magic DT shield and convincing some Frisks/Charas of Genocide AU’s to change, Frisk then worked VERY hard to convince Chara to help sans in battle to which Chara reluctantly agreed too, Papyrus’ image would show up every know and then to either give moral support or to help Sans in battle. Then they reached a Undertale Pacifist timeline that was being attacked by a LV9999 Dust!Ink, Sans at this point killed so many other HIM’s he broke the LV Cap and reached LV500 and had not only a soul of determination but also a soul of Fear after finding and killing a Bete Noir of a Dust version of Glitchtale.
In this new Timeline Sans wandered around until he found a now tired Undertale Sans about to be struck down by Dust!Ink only to block the attack with his bat and upper swing the bat into Dust!Ink’s jaw sending him flying back. Dust!Ink quickly noticed the extreme amount of Power and DT coming from Sans and summoned multiple very powerful dust sans’ including a LV20 Fanon!DustDust with 7 human souls, an Ultra!Dust, DeltaDust, Phase 4 Dusttrust, Last Genocide Dust and HyperDust. Sans readied his bat and prepared for the fight of his life. Sans first engaged both the DustDust and Ultra!Dust killing them both in a single hit with his trusty bat. He was then punched in the ribs by Delta!Dust and they engaged in a duel which ended up with Delta!Dust dead and Last Genocide dust being knocked into phase 2 and 50ft away from the battle. With out of the Frey for a bit Sans went and attacked Dusttrust engaging in a conflict that lasted 7 rounds and ended with Dusttrust’s head being knocked off its neck killing him. At this point Dust!Ink started to get annoyed and struck sans with his broom while he was about to strike down Last Genocide Dust phase 2 shredding his HP to 1 and was about to finish Sans off when a burst of DT exploded out of Sans along with the specters of Frisk, Chara and a fully animated Papyrus blocked the attack as sans’ HP quickly went beyond his max and his LV flickered between LV666 and LV99999 until stopping on LV99999. Sans’ Determination gave him a temporary boost to his LV allowing him to quickly finish off Last Genocide dust phase 3 in a single hit and engaged with Dust!Ink in a duel quickly killing him off after 3 turns and turned to Hyperdust and then two tridents popped out of the ground, one went through Hyperdust’s chest with the other being impaled through sans’ chest. Hyperdust was killed and sans teleported away as this timelines Undertale cast watched shocked at what they just witnessed. Sans managed too recover thanks to his DT and help from Frisk, Chara and Papyrus. Sans then teleported on a roof of a building and watched this timelines frisk play with papyrus and for once in a very very long time, Sans made a genuine smile.
Sans Personality[]
Sans during his Genocide route was no different from any other dust, but when his reset failed he became more remorseful and moped around a lot and fully regretted his actions. During his Dust Purge he was a combination of him during his Genocide route, normal sans fighting Frisk/Chara on the Genocide route and him during his remorseful phase having a mix mash of emotions all the time. Currently now Sans acts a lot like Sans but is more secluded and hangs in the shadows watching over the timelines Frisk, Papyrus and Sans making sure they live their best life while protecting them from danger (in secret of course).
Sans Appearance[]
Sans wears his usual attire, a blue hoodie (hood down), black shorts with white stripes and pink slippers. Has purple and red eyes (like most dusts) and usually Carries a Metal Bat made of a steel and titanium alloy that’s half his size and also has a mini soul container that has a piece of Papyrus’ soul in his pocket. Overtime his bones, clothes and bat has become covered and stained with both blood and dust but sans makes sure the mini soul container is always clean.

DETERMINATION[]
When sans’ HP drops to 1, 0 or below, Sans has a very good chance of getting back up with his hp healing to max and going 25% more than his make and making his LV SKYROCKET temporarily giving him increased stats. If taken down in this state sans will dust as normal, but if the DT wears off sans will return to normal with his hp staying the same and the DT will have to regenerate for 1 month until this can happen again.
Sans Weaknesses[]
Minor Insanity[]
Sans’ mind is not the same after his genocide route and journey causing him to become mad/insane though it is a lot better than Murder!Sans’ mental state. This causes him to sometimes not think clearly, have a clouded mind and/or act on instinct rather than thought.
His Past[]
Sans does not like to think about his genocide route and the pain he caused so if you lower his mental guards enough you can hit him where it hurts and either cause him to become demoralized or cause him to go into a blind rage making him REALLY want too kill you.
Sans Relationships[]
Frisk and Chara (Good Friend): during his genocide route and for a bit after sans hated Frisk and Chara with a passion blaming them for having to make him resort to the measures he took. But after Frisk showed remorse and helped sans escape his timeline he started to ease up more too frisk but it took him MUCH longer and some convincing from Papyrus in order for him to ease up too Chara as well.
Papyrus (Brother/Killer): Sans cares a lot for papyrus, during his genocide route it was his death that completely broke him and he could not bear the thought of him not being by his side so he took a piece of his soul in order to be with papyrus forever. It took sans by surprise however when papyrus found a way to project images of himself, his voice and summon attacks, it really helped sans in the mental state and allowed him to confront his emotions and past better.
Undertale Sans (Protects/Friend): Sans watches over Undertale Sans making sure he is safe and ok while remaining undetected but he did not remain infected by him for long. Undertale Sans confronted Sans one day with sans trying to dodge many questions until an image of Papyrus appeared an urged sans to tell the truth. Undertale Sans was glad that Sans told the truth but does not really trust him near his papyrus and frisk fearing He will kill them even though he saved them all before from Dust!Ink but has eased up to him a bit overtime. Sans also secretly envies Undertale Sans on how good his life is compared to his own.
Undertale Frisk (Protects): Sans keeps a close eye on Undertale frisk making sure she is safe and does not get into any antics, though he is fairly certain frisk either knows he exists or feels his presence as whenever he is near her frisk sometimes looks around like she feels she is being watched.
Undertale Papyrus (Protects): Sans watches over Undertale Papyrus making sure he stays safe and happy in his life on the surface, sometimes Undertale Papyrus will leave extra spaghetti someone plans to eat on an open window still to help it cool down which Sans will eat, Undertale Papyrus is still confused on how it goes missing while Undertale Sans knows.
