Error teleported inside an old, abandoned timeline, and walked through the judgement hall.
''heh. this place again. except... plain, vanilla and boring.'' Error told himself.
as he strolled, he felt something behind him. there it was. a human soul, ready to be taken. it seemed to look a bit like Frisk's, except from this timeline.
''perfect... just what i needed. i could really use this.'' Error smirked.
but then, he felt someone shortcut. it was his past self, Geno, alongside Hardtale Sans, a Sans who had a black crack on his skull, an orange flashing fire eye, and a red jacket with a grey hoodie.
''what do you think your doing?'' Geno asked, preparing a blaster.
''taking this soul as a way to power up Nightmare. your welcome, dickhead.'' Error said, circling around a blue soul strong on his finger.
''your not taking it anywhere, bastard.'' Hard!Sans grunted.
''cliche dialogue. when will the writing industry come up with supirior, fresh, and original dialogue? we're running out.'' Error frowned. ''regardless, it's time i be the one to put you in your places!''
Error then formed some strings into a whip, crackling the air. it kept missing Geno, who left a gaster blaster in his place, which shot onto Error.
Error recovered quickly. he teleported behind Hard!Sans, who filled up his fist with fire. he tried to punch Error, who dodged the attack. however, when Error tried to counter attack by making it rained stringed bone drills onto Hard!Sans, the latter turned, teleported, then he threw a knife. Error grabbed it, but then Hard!Sans threw feiry orange bones at Error, scorching him in the process.
shit.... i have to be on my toes... Error thought to himself.
the fight dragged on, with Error trying to use his soul strings to tie them both. but when he got one, the other always knocked him down to get the other out.
eventually, Error lunged angrily at HardTale Sans, but then time was stopped. Hard! Sans had done it himself. he then surrounded Error with red knives, then he clicked his fingers, and the knives slashed through Error.
''grrr.... i'll deal with you two soon... if this is it will be, dealing with you anomalies.... then fine. just you wait...'' Error grumbled as he escaped, beaten and sore.
as he tumbled out of the hall, Error then peeked at his hand. he still had the soul, to his surprise. how the fuck did he still have it? did he absorb it? regardless, he teleported away.
''crap.... he took the soul i thought giving him the shittiest beating would get him to drop it'' Hardtale!Sans drooped his face.
''it is okay, friend. one enhanced Sans will not be able to defeat to defeat all the people gathered in the OMEGA timeline combined.'' Geno put his hand on Hardtale's shoulder.
''you are right. but we still can't let him get away with this'' Hard!Sans spoke.
meanwhile
Dust pondered to himself. as he did, he felt Horror walk up behind him.
''um, Dust? buddy, you good? you seem lost in thought.'' Horror said. ''want a head dog?''. then he lifted up a head dog from his jacket pocket.
''nah, i'm good. tell me Horror, have you ever thought about betraying Nightmare because you realized what an egotistical megalomaniac he is?'' Dust asked.
''um, no? i havn't even thought of that'' was Horror's response. ''wait, are you the spy?''
''yep. it's me. see, Nightmare's been an insufferable bitch. i'm planning on ditching him. dosn't matter when, or where, or how. i just do. and i want you to join.'' Dust expressed.
''i see....... but... why? your abandoning the boss because of his tyranny? what the fuck?'' Horror was confused.
''i know it sounds crazy, but we must. he could sacrifice us any moment'' Dust said. ''now, i only have one question.... you with me?''
''okay, i guess....'' Horror said, shaking Dust's hand. Phantom Papyrus appeared behind Dust, pointing to Nightmare entering the room.
''the absolute fuck, you two?!'' Nightmare yelled. ''traitors!''
''hey, he started it'' Horror pointing to Dust, who then pointed to himself, knowing it was impossible to shift the blame from him.
''WHAT DO YOU TWO THINK YOUR DOING?! YOU TWO ARE FIRED!'' Nightmare angrily yelled. ''such a shame two, i was gonna give you the soul to power you two via extract-''
''we'll just take it by force.'' Dust smirked. Phantom Papyrus then grabbed the soul from Nightmare [yes, the same soul from earlier in the chapter].
''NO! god damn!'' Nightmare shook his fists and tentacles. he threw black spikes at Horror, who used his axe to block all of them. Dust used a trident to whack away two of the tentacles.
''hey what's going on-'' Killer asked, walking alongside Insanity Sans. the two were tired.
''.....um, boss? what's going on?'' Killer asked.
''your pesky teammate was the spy, and Horror is joining him'' Nightmare grumbled. ''now don't just stand there! attack, do fucking anything then just sit there!''
Killer nodded, throwing a few black knives, while Insanity threw his Papyrus head. both attacks missed, then Horror lept into the air, slicing Killer with his axe, who blocked it. Dust then used purple flames to attack insanity, who then ground pounded the floor. Dust was then saved by Phantom Papyrus, who grabbed him, then one two three'd Insanity.
Horror and Killer kept fighting, with Horror using a giant gaster blaster to block Killer's goop blaster. eventually, they both became tired. but Horror pulled out his secret weapon: a head dog. he ate it, healing him for some bizarre reason.
''plot convenience? really?'' Nightmare had the most annoyed expression.
''yep. it has to happen so the plot can move forward.'' Horror did a derp uwu cute face.
''shut up.'' Insanity said, throwing the Papyrus head forward. however Dust teleported himself and Horror out of the castle.
''well, that was a waste of the boss's leadership'' Insanity said.
''shut up, Insanity. you don't have a fucking in this'' Nightmare dingus slapped him.
''hey, i'm not the one who raped my captor with big tits'' Insanity backchatted.
[fun facts i thought i'd say quick:
1. yes, i will add Underlust. it's not that cursed. it's just....... weird. i mean, it's the sex au, but it's not that bad when you consider how the monsters in that au became fucking horny]
2. Dust leaving the villains sans was always intended to happen in this story
3. yes, Nightmare did rape Chara while she was captive, because he thought it would hurt Frisk far more, and to leave her to be forced to give up her soul.
4. this Horror sans has not yet met Aliza.]
