Chapter 1 : newer home with newer friends

after A beginning of a destroyer that denies death 
“Well this is the place” sans said 
“wowie it’s so empty. Too empty like there is nothing there ((except there’s strings way above us……wowie I wonder how long they are) papyrus thought), but that great new cuz that gives us a lot of space so let’s get working!” papyrus said
“I-i got t-the instruction manual” alphys said
”NYEH let get to work” papyrus said
everyone goes to do their thing while sans Look up to the strings at the sky than said “I’m keeping an eye on you strings”
than everyone started building a small village in the fatality void sans teleports back to his world getting some resources
”so we put grillbys there…..than we put muffet shop next to it…..alphys lab goes there & undyne is my neighbor Nyeh heh heh….sigh” papyrus said 
undyne became concern than ask “hmm what’s wrong paps?”
papyrus replied “nothing I kept remembering that doppelgänger sans a few hours ago. That can’t be him. Sans would never do this”
undyne said “he was like this because of his master…..look if it make you feel better I will crush those two punks!”
papyrus smiled than says “nyeh! heh! heh!”
(….I hope things goes well. I hope this void doesn’t do anything harmful) sans said in his thoughts
== 10 days later ==
it has been 10 days ever since horrible assault while everyone building their newer home but. Papyrus noticed a……red tentacle grabbing a hammer
((Hm? I could be wrong but non of the monsters I know has the magic to use tentacles) papyrus though) than he created a long bone & slowly walk the direction the tentacle go’s to
(papyrus though (holy crap this is kinda scary. This might be a freak or some kind of new species that live here. Alright here I go))
papyrus than jumping in front of the tentacle creature than said “nyeh! It is I. The great papyrus & if you don’t tell me what you’re going to do with that hammer. I wi-……” he relies that this mysterious figure is a skeleton child who has dark grey bones who has a face similar to sans
“nyeh another sans look like?! & he has tentacles on his back!. But mr tentacles what are you doing here” Said papyrus while looking surprised
“I’m not sans I have a name it’s c.o.d.e anyway I’m helping you build & trying to find my father” c.o.d.e said
papyrus replied “well i don’t know who your father is but I appreciate for you helping us” 
“your welcome also were you gonna hit me with that bone?” c.o.d.e said while smiling
Papyrus was shaken by the fact he could have hit a child with a bone.…again & said “umm in my defence. I thought you were a stealing from us” with a nervous smile with C.o.d.e looking at the hammer he just took
meanwhile with sans & his ghost buddies in the destroyed city. Most buildings are nearly destroyed while there are blood & dust on the streets 
”damn where is chara. We been looking for her- eh I mean. Them for days! Frisk are you sure chara is here with us?” Hank ask while picking some buildings
frisk said “ first chara is fine with all pronouns second if they aren’t here with us than where are they. Where would they go?”
While sans is next to the big crater that he made than he found toriels dusty clothes & he gets flashbacks on what horrible sans did. He clench his fist & while looking a bit angry than ask “so will my current strength be enough to beat horrible?” While looking at Hank with a serious face
Hank answered “you should test your power soon so we can see the results….but i can’t still believe it Mike is still alive & still wants to destroy humanity……..” 
“But what is his problem? Why do all of this? Just what is wrong with this Mike figure you keep on talking about? Did something happen to him? Like something terrible?” sans ask 
”i guess? When I first met him he was very angry. Not just at me but at every human in his sight“ Hank said 
sans was puzzled by this & said “hmmm. If that so then. The humans did something to him. Something that make Mike to caused this madness “ 
“Ok so after we deal with sans’s doppelgänger. We will try to save Mike!” frisk said 
Hank was shock ”hold up? Save Mike!? All he will do is continuing to kill more innocent lives!” he yells 
(…the kid still has that determination to save monsters. I mean it work once. Can it work again?) sans said in his thoughts 
”but we can’t kill him!. Look if human did something bad to him. That means deep down he is in pain!” frisk yell 
Hank yells back “look kid not everyone can change! He. Is. Long. Gone!!. I hope you realise that.” 
Frisk became mad & then screams “what do you kno-“ 
“all right you 2. Calm down let’s focus on Horrible sans first then we can figure out what to do with Mike. But remember I’m still the judge…” sans said calmly than use blue magic to lift multiple destroyed buildings than teleport to Fatality void 
“I’m back” sans said while dropping the buildings 
c.o.d.e noticed & said “oh! Father is here” 
“oh hey san- wait what did you say?!” Papyrus said in shock 
sans confusingly said “did you call me father? I don’t even know who you are”
c.o.d.e who just smirked than says “HEH. You were little taller than me but after you came here you became tall as paps” this shock sans
sans “wha- you know that I been here!?!”
c.o.d.e explained “well after your appearance change this place copy your code & use it to create me so I could be your clone but I rather be your son” 
Papyrus said “hold on does that make me an uncle!?” 
sans was stunned than thinks “(jeez…. what did this place do to me)” than became calm than said “well uuuuh son what do you want” 
c.o.d.e said “to spent time with you father I can help build” 
sans reply “k you can help……. Son” 
c.o.d.e notice something “ ! This place has finished its coding come out guys” than 10 more people come out of the ground just to help with the building 
“this place have copied code of 41 beings here than created 10 more beings anyway back to work” c.o.d.e said than he use code manipulation to use the destroyed buildings code to turn into normal looking buildings 
sans said “i knew living this place was a bad idea oh well that impressive son! Keep up the good work”
papyrus run to the other people and said “hey everyone! I’m an uncle NOW! Nyeh heh heh!!!
sans said “heh at least pap is enjoying it”
== 3 months later ==
after 3 months with C.o.d.e help they were able to finish building their newer home
C.o.d.e Add a indestructible country wide floor on top of this white void’s ground then the builders add a large island size city & a big town on that same floor. while C.o.d.e add The Usual nature & mountain the stuff that the citizens used to see everyday back in their timeline. 
Now that indestructible country wide floor is inside of a dome that is the size of a planet & how the dome works is by mimicking on how time work on earth. It can turn to day & night in the inside while the outside the dome glows & glooms
meanwhile with the skeleton bros
“Finally we finish building our house sans” papyrus said
”heh yep it look just like the one in the underground except my son has his own room in there” sans said
“Let’s go inside so I can tell you more about Fatality Void” C.o.d.e. said
(to be honest I’m not fine fully. That doppelgänger & his actions keep being on my mind every minute) sans thoughts
The skeleton family walks to their house
”wow I feel nostalgia nice work paps &……my…son heh I’m still not used to having son” sans said
”it was a team effort sans since you stop being lazy anyways nephew tell us more about this void” papyrus said while smiling
(…it’s not like I can sleep in peace.) sans said in his thoughts
c.o.d.e explains the fatality void “to be honest I know a lot but not everything about it so what I know that this place exists for thousands of years and you got a less than a fraction of its power father but about the name I made it up I don’t know it’s true name” 
“but why me I just came here by accident” fatality sans said 
“because of that soul you absorb its connected to this place” c.o.d.e replied 
”about getting less than fraction I the great papyrus has noticed that all of humans & monsters in the fatality void has got less than fraction of its power 
“huh…your right paps not only I noticed i also feel it not only the people. But the building as well anyways I will ask Hank about my soul later. So how strong am I?” fatality sans said 
”well fatality void got an infinite supply of infinite power that beyond the concept of dimensionality & space-time” c.o.d.e said 
”wait so that mean everyone in here. Have that power” papyrus said while shock 
“Well yes but no you all don’t know how to use the full extent of the fatality void infinite power so right now everyone here with that power in its current state is just well 6 to 10 dimensional” c.o.d.e answer 
“So how powerful am I at currently” fatality sans ask 
“I scan you & according to my calculations your pretty powerful” c.o.d.e said 
“be more specific?” Fatality sans said 
“you’re strength durability & your power are 8D & your speed is massively faster than light” 
“wow….that……is…..insane wait if I’m this strong I might destroy that guy who destroy my world I just need to find him” Fatality sans said in a serious tone as his body start glitching 
“well good luck on that there in fact a multiverse containing an infinite amount of alternative universe’s that contain infinite timelines. That also includes the AU you came from” c.o.d.e said
fatality sans said “well damn. It gonna- ugh….I will be back”
c.o.d.e said “father? Where are you goin-” but sans teleported away already while leaving frisk & Hank behind
“Nyeh! What is that skeleton doing!?” Papyrus said
c.o.d.e replied “I don’t know uncle paps” 
papyrus said “hmmm oh well I will cook some spaghetti for him” 
“uncle last time you cook it went terribly wrong let me help you” c.o.de said as he follows paps to the kitchen 
Frisk ask “should we help?”
Hank answered “I never cook before & I’m sure that neither do you. So I guess no”
=== Few hours later ===
sans teleports back to the fatality void outside of newer home he said “damn this soul is forcing me to kill but I feel like those are just glitches in the multiverse I can’t tell I’m doing good or bad……….I have seen a hundred AUs. A lot of those glitches. A lot of alternate versions of me. I should give myself a new name for no confusion how about fatality error sans…..that might do cuz i keep glitching & I have a fatality soul also I’m kinda lazy at naming but should I tell them about my killing. Nah I’m too lazy to spill the beans (teleports back to his house) 
the skeleton family are having dinner 
apparently C.o.d.e teach papyrus how to cook a very good & healthy chicken 
“Wowie this taste delicious we did good my little nephew” said papyrus 
C.o.d.e Smile than look at sans & said “how is the chicken father” 
sans than pat C.o.d.e’s heads than said “i love it. You 2 did great” 
meanwhile outside of the skeleton house 
Frisk & Hank have an conversation or you could say that this is an argument 
Frisk said “dude I help the entire race of monster in that mountain! What difference about 1 person!?” 
Hank said “last time I met this “1” person. He show me that he can handle or even beat me! & What part of “my fatality soul transcend the capabilities of your determination” did you not understand!?” 
Frisk argues “well how did you know about that information!? Maybe you’re underestimating me!” 
Hank said “……underestimating? My father hades told me to never underestimate people & he the same guy that create the first fatality soul that ever exist…..He knows everything about The fatality soul……(inhale than exhale) you know it’s getting dark. So let get back to the house ” 
Frisk said “ok we will discuss this later……” 
The 2 ghost human go through the walls of the house than rest inside sans’s soul 
=== later that night ===
Sans was walking into the old city that is once from his old timeline but that was once destroyed city is fixed as if nothing happened. In this beautiful day outside. He was Being relaxed by the singing birds & the blooming flowers than sans saw a bench & tried to sleep on it but after 30 seconds when he opened his eyes. He saw the city being in ruins. The sky was red & blood & dust is everywhere 
when he gets off the bench he saw something terrifying next to his feet. It was toriel head on floor sans back away for a bit but than he felt a presence behind him 
“turn around & shake my hand” the mystery figure said with a deep sinister voice 
when sans turn around suddenly he got punched through the chest than gets lifted up. The person he saw was horrible sans who was taller than him & have the top part of his skull destroyed. Horrible sans looking at fatality sans with a sinister grin than grabs his face than crushing it like it’s nothing 
than sans suddenly woke up with a cold sweat & was breathing heavily than said “holy shit. That was a bad dream” than look at chest with serious look “I need to be stronger” he said than slowly went back to sleep 
== (10 hours later) ==
fatality error sans was chilling on his old couch. But is bothered by that nightmare he had & he was thinking about horrible sans & his actions until fatality error sans has remembered the reset button so he tries to summoning it. It took a few seconds but he did it but unfortunately the damage on the reset button is still there 
“damn that guy was right the button is destroy I guess I can’t reset anymore” 
“that doesn’t matter anyways the horrible damage that he caused our AU was so bad that not even the reset button can fix” Hank said
“Damn…I’m gonna give him the biggest bad time ever wait I gotta ask you something where did your soul come from Hank” fatality error sans ask 
“well I inherited it from my father. Hades other than that idk but I think this soul’s power come from this place” Hank replied 
“Hades…. Couldn’t your grandparents come up a nicer name for your dad? Well My……..son did tell me that fatality void had existed for thousands of years” fatality error sans said 
“Ugh I’m kinda getting sick of waiting when will horrible sans yet? Or batter yet why don’t we find him” Hank complain
“How can we find HIM when we don’t where HE is. Just why do you want him for* fatality error sans said
“I want only 1 thing from him I just need to know if Mike is behind this” Hank said while frustrated
“ok what is with you & Mike. Who even is he? You make it sound like he is a bad person” fatality error sans ask
“Mike IS a terrible person. I was there when he attack me and my family’s village” Hank answered 
“Look I will judge his actions when I meet him. But shouldn’t he have a chance to be redeemable-” fatality error sans said calmly
“That ancient Asshole doesn’t deserve a second chances!” Hank yell 
than frisk came out of nowhere & they where shock & said “hey! I know he a bad person right now but that doesn’t mean he shouldn’t get a Second chance”
“ok ya know let’s be chill about this. Just need to focus on Horrible sans first” fatality error sans said
“Yeah where did he come from? ” frisk responded 
Fatality Error Sans said “well he did say that he was from an alternate universe & my son did say that there was a multiverse” 
“Wait how old is Mike again” frisk said 
“well you (softly point at Hank) mentioned Mike existed before the war between humans and monsters & that happened many years ago” Fatality Error Sans said
“& so far monsters can’t live for that long. So either he is very old man or he’s passed away” Frisk said while confused
“But Mike is not a normal Monster. He was able to take on more than ten humans ” Hank said
“look even if we find horrible sans. There’s a chance that we can not win. I just learn how to use my new power. I need more experience. Plus if Mike is still there he might be absolutely powerful” Fatality Error Sans said
Hank said “good point. Mike madness would make himself stronger after he learn that he is on par with me”
Fatality Error Sans answer “damn we need to prepare but how?” 
than C.o.d.e teleport here when he heard the conversation than he said “hmmm I got options for you father” 
“heh attaboy tell me those options pls” Fatality Error Sans said
“well tell me what abilities you got. Maybe you can ask other to help to you ” C.o.d.e said 
Fatality Error Sans replied “hmmm. Ok son. You see my Bones & blasters got some new tricks that I haven’t been familiar with & I got an infinite amount of red & blue strings, I got this sword & a broken reset button” 
“You can ask muffet & undyne for help. you can train with them so you can experience the potential of your abilities” C.o.d.e said 
“ok thanks ki- wait how old are you” Fatality Error Sans ask 
“father this will shock you I’m in fact 0 years old I’m just smart for my age” C.o.d.e said 
Fatality Error Sans was surprised than said “….woah that very Very young but why do you look like your 5 years old” he ask 
“i can change my height & size father” C.o.d.e answer
“okay kiddo I got to get going & also you can call me dad” than Fatality Error sans teleport
“ok…..dad” C.o.d.e said after smiles
Fatality Error Sans teleported in front of a place called spider-grills. A restaurant with fast food & pastry. He open the door than goes in.
grillby was surprised who came in “well look who came in”
”heh heya guys” Fatality Error Sans said
“Hi sans” a group of monsters & humans said
Fatality Error Sans ask “so grillby a week ago, you & muffet decided to work together to make a perfect restaurant. So I gotta ask. Has she been ‘bugging’ ya lately”
a group of monsters chuckle when sans made that pun while muffet was annoyed by it than said “spiders are arachnid. Bone head”
grillby said “she was at first but we were able to get along. We even created something new on the menu called a fries donut”
Fatality Error Sans said “heh that’s nice. Can I get just fries & ketchup”
muffet said “sure only 9999 gold”
grillby said “muffet-“
”Ahuhuhu just kidding” muffet said
grillby said “sigh anyways you two give sans his fries & ketchup”
“Hmm?” Sans said than he noticed 2 skeletons 1 with a missing jaw & the other with a 1 red arm. Sans said “wait are those one of those people C.o.d.e created a few months ago
grillby said “well yes. When me and muffet met those 2. They asked us to give them a job. So we did & than we saw that they are pretty good at being waiters. But sans I got to ask, what is with you in these past few months? You haven’t visited me for 3 weeks & for these past few months those guard dogs & spiders told me & muffet that you look stressed sometimes & your brother papyrus told me you have been having nightmares most of time when you sleep. Are you okay?”
sans had a flashback of him getting punch through the chest by horrible sans when he was fatality sans & remembering the time when horrible sans kills toriel than said “…………I got a lot on my mind.…………”
the skeleton with the red arm places the fries & ketchup right in front of sans
sans said “thanks waiter”
the skeleton with the red arm said “no problem & just call me causality” than he walks away
sans said “so grills I’m not here just for food. I’m here to ask muffet to spar with me along with undyne”
muffet was surprised by this than ask “wait you want to fight me & undyne! But………why?”
sans said “well I need to experience the length of my powers & abilities. Also I can do this” than he use his blue strings to create a spider web
muffet said “wow when can you do that?”
sans said “when me & my family finished our house I discovered I have blue & red strings. So I want to learn how to used them”
muffet smile than said “hmmmm ok I will help you”
grillby intervene the conversation & Said “hold on sans can I join?”
sans “um why?”
grillby put one of his hand on sans than used his other to point at sans so hard that a sudden gust of wind came out. Everyone in the restaurant felt it & grillby Said “so if I beat you. You can finally pay your tab after all those years”
muffet Looks at grillby confused & said “did you have to be dramatic about that?”
grillby put his hands down & said “well my 6 armed partner. Sans haven’t pay his tab for as long I can remember. He has to pay it one way or another”
sans smiles said “ok you got a deal grills. So 1v3 lets go to undyne house. I know a shortcut”
muffet said to the 2 skeletons “hey you 2 can you take care of the restaurant”
causality smiles & said “yes ma’am”
sans teleported along with grillby & muffet to undyne house this house look similar to the one in the underground & it seem to be 10 meters away from sans & papyrus house than sans ring the doorbell next to the door. But nobody came although the group saw a sign on the left that says training zone while pointing at a pathway that seem to lead to the entrance of the training zone
“Weren’t there supposed to be a dummy there?” Frisk said while being invisible to grillby & muffet
grillby said “undyne must be at this training zone” than the group turn left & walk forward than turn right & walk forward again
they walk for 5 minutes straight until they at the entrance of the training zone and it is behind undyne’s house
sans, grillby & muffet are surprised on what they see. The training zone is the same length as a small city & it’s appearance seem to be similar to the place where undyne & other specific monster live in a place called waterfall 
there are walls that are the same colour as waterfall, there are echo flowers, waterfalls & a dumpster that seem to have trash’s & has 5 dummies & one of them seem to be angry although there could be more of them hidden
muffet said “wow did undyne build all this on he-“ than someone crash into the ground. The dust cleared & it seem that there 2 people fighting in a big Crater it appears to be. Undyne & papyrus
”wowie undyne! You’re certainly stronger than I remember a week ago” Said papyrus
”you too paps you would be piles of bones when I slam you into the ground!” Said undyne
Papyrus notice sans, grillby & muffet &said “Oh hey sans, hey grillby, hey muffet”
but than undyne grab his 2 of his shoulders than said “hey paps you forgot something. DON’T LET YOUR GUARD DOWN!!” Then undyne launch herself & papyrus up into the air then she turn papyrus upside down then intensely slam papyrus into the ground. The training zone was shaking by the impact 
papyrus was in the ground. Only showing his ankles than he was able get out from the ground by doing a black flip than said “hey undyne let hold our little spar. Because it appeared my brother & those 2 seem to visit us”
grillby was trying to process on what he just saw “papyrus ya okay? You got slam into that ground pretty hard”
muffet was shaking by undyne powerful strength & thinks (she kinda scare me now)
sans was surprised by this. He knew papyrus train with undyne most of the Time but paps never said it was this intense 
Undyne said & ask “what ups bonehead mini- oh I kept forgetting that you became taller, i was always used to you being short. So what are you doing here?”
Sans said “well me & my pals were here because I need experience in my capabilities & limits. So this might be a little shocking to you but I want you, my bro & those 2 business partners to fight me all at the same time”
undyne look at sans surprised, sans never ask this at all
Meanwhile
The ghost of Hank & frisk at the entrance of The training zone. Having the same conversation they had yesterday 
“Ok you said let talk about this later yesterday right? Just Look just how bad Mike is? What makes him irredeemable” frisk argues
Hank looks at frisk with a disappointment than said “look kid I met him way before the war between humans & monsters even happened & he fucking suck. He can literally punch through your chest like it’s nothing. He did terrible things that I see no monster ever did. So trying to save him will give you nothing but a painful death”
Frisk look at Hank with a serious look than said “people who have hurt you can be forgiven if they are willing to change”
Hank closes his hands angrily & said “Mike is not one of them”
Back to undyne after hearing sans request. She was surprised & confused
“Wait for real? You want 4 of us to fight you well.” Undyne said than summoned a spear & point it at sans
”I knew you became less lazy but I didn’t think you would ask something like that. You really change sans. Now ENGUARD!” She said & yells when undyne slam her spear on the ground so hard that the wind pushed sans 30 meter away from her & the rest
muffet was shock & said ”wait we are doing this now!?”
grillby summon some fireballs ”it appears so. Let see if we can keep up”
Undyne point at sans than said “I hope we don’t accidentally kill you tho since you have 1hp”
”heh. You should know. I USED TO have 1hp” sans said as he smash his head on a rock & the rock did nothing. Undyne smirked
”so sans. Get ready to feel the justice from the leader of the royal guards!” Undyne said than fired a spear at sans
Sans than blocks the spear with a wall of bones but the spear pierced through the bone wall. Sans go dodge the spear in 2 Second but undyne grab him in 1 second than she launched into the air than slam in the ground creating a crater. Both of them jump out of the hole
“Hey bonehead! Did ya feel any pain from that!” Undyne shouted!
Sans just does his usual smile & said “a little bit although by your expression. What you did just now was just a taste of your power”
“I’m not standing around anymore. I’m getting him to pay his tab” grillby said as he created fireballs around him
”nyeh heh heh I can’t wait for my brother to feel the great wrath of the newly improved, great papyrus!” papyrus said as his created bone swords on his hands
”Ahuhuhu I’m just gonna take his wallet” muffet said as she using her webs
Sans just chuckles than he open his eyes while missing their pupils & said “come. Let’s have a bad time”
Papyrus pointed his sword at sans than sans’ soul turned orange than he got automatically thrown at undyne, she tried to punch sans but he dodged it & use blue magic to throw undyne at bone wall than dodges a bunch of fireball & block papyrus’s swords with a bone
“Nyeh heh heh, sorry brother but this is what you get for not picking up your sock” papyrus said as he kick sans in the face, sans tried to use blue magic on paps but he nullified it
Sans was shock “Wha-“ 
“I was working on a technique, prettty great right?” Said papyrus 
sans remarks “yep pretty co-“ but he noticed grillby charging a attack than he shoots a laser beam made out of fire, sans counter it with a fatality blaster, the 2 beams clash & caused an explosion than muffet use her webs to throw a bunch of boulders at sans, he dodged with ease & fires a barrage of bones at muffet
than a lot of skyscrapers size bones came out of the ground, sans was caught off guard by this as he landed on one of the huge bones undyne came & punch sans so hard that he went through 4 giant bones
“Damn they’re good, I can’t win like this gotta use some of my new abilities” sans said as he saw undyne shoot a barrage of spears at him & sans lifted his hand than created a magic shield to block the spears, undyne smiles than fires a big spear at sans
”heh” sans said as he removed his shield than he erase the big spear out of existence, undyne was surprised while sans used his blue strings to grab undyne & slam her into one of the giant bones
sans look at his hand as he was amazed by this & said “heh, I see this new world has created a new version of me & with that freak out there, I can’t afford to stay lazy anymore”
more coming soon
