TeaDaddy_ requested the idea of Error x Child <Random Sans AU> FLOOF

But I decided FGOD Error and Child!Horror and TimeKid!Sans

This may be really short, but I'm not sure. (Yes, We'll see the return of Mama Error but maybe prior to meeting the crew, or maybe in a different timeline.)

Error opened the portal by complete accident. He wanted to go literally anywhere but where he was. He didn't intend to stumble into another multiverse.

You probably want the whole story. It's rather simple.

Error was just minding his business in OuterTale, before Ink came, did the whole "I'm the creator and I WILL defeat you" spiel, which Error just kinda got ready for the beating, continuing to look at stars through the entire thing.

When Ink lunged forward, Error teleported away from his attack, landing a little ways away from the whole group, dodging away from the attacks and not fighting back. He was tired. And when Ink finally landed a purple chain paint on Error, that dropped him to his knees, where the rest then began to kick and beat Error.

He wanted to be anywhere but here. He didn't know where, but he didn't care.

Back to the present.

Error lands into an Anti-Void, but he can tell instantly it's not his anti-Void. He's in someone else's home. And he's uninvited.

Error sits down, sighing softly. He doesn't understand how he could access such a strange place.

"Oh, Hello newcomer." Error jumps, turning to face a Gaster he doesn't recognize.

"Uh...wh0 4r3 y0u?" (Uh...who are you?) The Gaster blinks, before smiling gently.

"Who I am does not concern you. These two young ones, however, do." The Gaster moves to the side, revealing a child-like Sans with a crack in his skull and a second child who looks unfamiliar. The cracked skull child notices Error and immediately runs over.

"EWWOW!!!" Error catches the child, hugging him close.

"H0rr0r. Nightm4r3 w45 w0rri3d 5ick whi13 y0u w3r3 mi55ing!" (Horror. Nightmare was worried sick while you were missing!) Horror drops his happy face, slowly saddening, nodding in acknowledgment.

"N0w, 3xp14in t0 m3 wh4t h4pp3n3d 4nd h0w y0u g0t h3r3." (Now, explain to me what happened and how you got here.) Horror nods, the second skeleton walking over. He looks like a kid Sans but with goggles on his head.

"W-well...I-i was a-alone and s-stumbled into a-an AU...t-turns out i-it was T-tk's AU. B-but Ink f-found me a-and tried t-to hurt m-me. TK c-called out a-and we l-landed here." Error nods, looking over TK, who meets his investigative gaze with a calm demeanor.

"Th4nk y0u. H0rr0r i5n't th3 m05t p0w3rfu1 0f th3 cr3w." (Thank you. Horror isn't the most powerful of the crew.) Error then looks at the Gaster.

"C4n w3 g0 h0m3 n0w?" (Can we go home now?)

"I suppose. Good Luck, Child of Change." Error raises a brow, but stands up, holding Horror. TK steps closer to Error and the Gaster opens a portal below them to Outertale.

"Hahah! You're back-" Ink is cut off as he looks at the situation. Error holding Horror like a mother would a child, and TK is hiding behind Error's legs. Error quietly looks at TK then at Ink, pushing the small child towards the creator as he opens a portal.

"H3r3'5 y0ur mi55ing br4t. I'11 t4k3 min3 h0m3, th3n w3 c4n c0ntinu3." (Here's your missing brat. I'll take mine home, then we can continue.) Error steps into the portal, not noticing the small follower he had as he walks towards the mansion to where Nightmare is losing his mind in the living room. The others are all hiding from the tentacles.

"4h3m." Nightmare looks at Error, and rushes over, removing Horror from Error to hug him close.

"I WAS SCARED! WHERE WERE YOU?!"

"4n0th3r mu1tiv3r53 which I 0n1y f0und by 4ccid3nt. N0 id34 h0w h3 g0t th3r3." (Another multiverse which I only found by accident. No idea how he got there.)

"I-i can explain." The two adults jump and Horror smiles.

"TK!" TK waves, smiling hesitantly at the two dark skeletons.

"When Ink attacked Horror, I quickly called a friend of mine, cause they come from a multiverse FULL of TKs, and that friend decided to pull the both of us there until someone from here came searching." TK gets a thoughtful look.

"I didn't think it'd be the Destroyer, but oh well." Error looks away from TK.

"If y0u th0ught Ink w0u1d g0 100king, I c4n 455ur3 y0u h3'd n3v3r h4v3 g0n3 100king. H3 d035n't c4r3 4b0ut 4ny0n3 th4t c4n't imm3di4t31y 53rvic3 hi5 n33d5. H3 pr0b4b1y 5pr34d 4 rum0r y0u di3d in th3 fight t0 du5t H0rr0r, in 53rvic3 t0 th3 gr34t3r g00d. Th4t t3nd5 t0 b3 hi5 M.0." (If you thought Ink would go looking, I can assure you he'd never have gone looking. He doesn't care about anyone that can't immediately service his needs. He probably spread a rumor you died in the fight to dust Horror, in service to the greater good.) TK looks at the ground, but Horror jumps free from Nightmare and hugs TK.

"It's okay tho! You d-don't need him! We're friends!" Horror smiles innocently, while TK looks at Horror sadly.

"So that's where he went." Everyone turns to see Blue standing in the doorway, Blue smiling 'innocently' yet sinfully. Blue kneels down with his arms open as Horror gasps, his single eyelight turning to a giant star as he runs into Blue's arms.

"UNCLE BLUE!!!" Blue stands, twirling around with Horror, hugging the child close.

"Hey TK. What's up?"

"Ink..he really wouldn't go searching for me if I were missing?" Blue sighs.

"TK. He wouldn't even go searching for me or Dream. He doesn't care if we go missing, because MIA or dead is better than us telling everyone his deal." TK tears up, and a black hand with red and yellow phalanges lands on TK's head, gently patting him. TK looks at the owner to find Error looking away from him, a soft blue blush covering his face.

"It'11 b3 0k4y. Inky'5 0v3rr4t3d 4nyw4y5." (It'll be okay. Inky's overrated anyways.) TK lets out a snrk, then a snort, then a giggle, finally releasing a full-blown laugh.

"O-okay, haha, yeah." Error gazes down at TK, kneeling beside the small one and looking at Nightmare.

~Bonus~

"No."

"Nighty!"

"Error! We've already adopted Dust, Horror, Killer, Cross, Epic, Fell, Razz, Black, Lust, Fresh, Geno, and Blue." Dust shrugs, ignoring what's going on. Horror doesn't care. Killer, Cross, and Epic all take offense to Night's words. Fell, Razz, and Black are in a three-way sparring match. Lust just shrugs, relaxing on the couch. Fresh chuckles, shaking his head and skating out. Geno sighs softly, smiling at Blue, who gets a dark happy look silently stabbing Nightmare in his daydream.

"P13453?!" (Please?!)

"We are NOT adopting TK as well!" Error juts out his bottom lip, wobbling it as tears form in his eyes.

*Nightmare feels his sins crawling on his back.

"F-FINE! WE'LL ADOPT TK TOO!" Error instantly smiles, not a trace of sadness as he hugs his new child happily.

"Y4y!!!: (Yay!!!)
