Undertale: Fay Route
Summary
Frisk had RESET so many times. Nothing changed. They just couldn't save everyone. After managing to rid themself of Chara's influence after going on a genocide run, Frisk wouldn't give up until they could save EVERYONE. So when a strange girl appears out of nowhere, it's obvious that Frisk would be cautious. But Fay gives the child no time to worry about such things, as she soon immersed herself into the human's adventure. Our little God 0 is in the world of Undertale, and it's troll time. Now, if only she could make puns...Rated 'C' for crack fiction... Rated 'M' for content... Enjoy the stupidity...

"... OH..."

"Fairy... What exactly-"

"ERROR! You have not yet met the criteria to be cleared for this information! All information is classified. Please see a supervisor if you have any questions... There are no supervisors..."

Fay answered almost robotically. It would have been funny if Sans weren't so suspicious of the girl. Said girl was now fidgeting under everyone's gaze and avoiding eye contact.

"Th-there are just some things you shouldn't know. Not yet at least... I will tell you eventually... But... It's still too early... Understand?"

Frisk was still grabbing at Fay's dress. They sighed and patted her hand in a show of comfort. Frisk couldn't tell if this girl was a genius, or an idiot. Maybe both? Is there a word for that? Oh, right, 'crazy'. As Fay continued to avert her eyes, Sans glowered at her. But he understood, sort of. Deciding that it was too much trouble, Sans huffed and relaxed a bit. He did not have the energy to deal with this.

"yeah, whatever Fairy... hey kid, did you see that weird outfit that my brother is wearing? we made it-"

Fay nodded, accepting Sans silent agreement. Stepping back, she let Sans talk to Frisk about Papyrus' outfit. She needed them to bond after all. After they finished, Frisk motioned for Fay to follow them. The two came across an ice cream vendor and ended up making his day. By buying half of his stock. Frisk offered one of the ice creams they had bought to Fay. She however declined the offer and told them to keep it. After walking for a while, Frisk and Fay once again found themselves in front of Pap and Sans.

"HUMAN!!! I HOPE YOU'RE READY FOR... SANS!! WHERE'S THE PUZZLE?"

"it's right there. on the ground. trust me. there's no way they can get past this one."

Looking down, Fay spotted a piece of paper. Frisk simply walked right past it, completely ignoring the thing. Fay however picked it up and folded it cleanly. Placing the word search in her pocket, Fay turned her attention back to the cast.

"SANS! THAT DIDN'T DO ANYTHING!"

"whoops."

The brothers started arguing about cross words and word searches. They couldn't decide which was more difficult, so they turned to the humans. Frisk agreed with Sans, saying the word search was easier. When everyone turned their attention to Fay, she smiled nervously and waved.

"WELL? WHAT ABOUT YOU TALL HUMAN?"

"Um... I've never actually played any of those before... So I have no idea..."

"WHAT? HUMAN! HOW COULD YOU HAVE NEVER PLAYED SUCH COMMON PUZZLES BEFORE?"

"Um... I'm a deprived child?"

"wow. what a puzzling problem, how dare your parents not let you play with cross words and word searches."

"INDEED!-"

Papyrus was about to continue questioning Fay when he suddenly stopped talking and his eyes bugged out... After suddenly appearing...

"OH MY GOD!"

In a fit of annoyance, Papyrus just stormed off, leaving Fay, Frisk, and Sans to themselves. The small group exchanged looks of humor and embarrassment before Fay let out a cough.

"Welp, we should get going... See ya!"

Tapping Frisk on the shoulder, Fay started walking off to get to the next puzzle. As much as she loved this, she doubted she could keep doing puzzles for the length of her stay in the underground. Not when she could just skip them... And how inconvenient was it for monsters who decided to travel? Even if you knew the puzzle by heart, it would get annoying having to solve it just to visit a friend. Fay was thinking this as she and Frisk passed a plate of frozen spaghetti and a useless microwave. Smirking at the sight, Fay wondered just how bad Pap's cooking really was. Not that Fay would ever know. She couldn't eat food. Maybe sweets, but monster food was surprisingly lacking in sugar. It was hard to explain, but Fay couldn't eat it. It was kinda like trying to make a carnivorous animal live off of grass... Poisonous grass...

Fay was brought out of her thoughts when Frisk once again pulled at her dress. Looking down at the human, Fay tilted her head, silently asking what was wrong. Frisk was silent a moment before finally finding the right words.

"Piggy back?"

Fay smirked. Not against the idea, Fay crouched down and showed her back to the human. Frisk delicately climbed into Fay and wrapped their litter arms around her neck. Straightening herself up, Fay shifted Frisk so she had a better hold on them. Smiling happily, Fay looked back at the child and let out a laugh.

"Getting lazy are we?"

Frisk shook their head 'no' and once again seemed to be struggling for words. Fay gave another laugh and waited for the human to gather their answer.

"Can't fight if not seen..."

"AH~ Smart. Well then, let us be off! Navigate the way little captain!"

Frisk let out a giggle and just pointed forwards, so Fay continued the way she was headed. She wouldn't get tired of carrying Frisk. She didn't need sleep, though that never stopped her before. Sleep was nice. Fay quickly solved the next two puzzles and managed to sneak herself and Frisk past the married dog couple. Humming to herself, Fay walked up to an unsuspecting Papyrus and tapped his shoulder. The poor skeleton jumped in surprise but quickly regained his composure.

"AH! HUMAN! I SEE YOU HAVE MADE IT PAST MY TRAP!"

Frisk nodded enthusiastically and mumbled something about eating the spaghetti. Papyrus' eye sockets grew in joy and he started smiling. He was almost crying from joy.

"REALLY?! WOWIE... NO ONE'S EVER ENJOYED MY COOKING BEFORE... WELL THEN!! FRET NOT HUMAN! I, MASTER CHEF PAPYRUS... WILL MAKE YOU ALL THE PASTA YOU COULD EVER WANT!"

After his little outburst, Papyrus started laughing and ran ahead. Fay was covering her mouth to keep from laughing and looked at Frisk from the corner of her eye. They seemed to be slightly sickened by the idea of eating the promised pasta, but kept silent none the less. Able to control herself now, Fay lowered her hand and continued on. Pap was waiting and explained the next puzzle to the two non-monsters. Again, Fay paid the conversation no mind. When Papyrus finally finished talking, Frisk pointed forward to the start the puzzle, but instead Fay backtracked a bit. Frisk pulled her clothes in confusion but Fay only winked in response. Walking up to a tree, Fay pulled a hidden switch and went back over to the puzzle. Stepping on the switch, all the circles turned green. Papyrus was rendered speechless and Frisk smacked their forehead. They had forgotten about that cheat. Papyrus finally found his voice and complimented them for solving the puzzle so quickly. And without his help too! Moving on, Fay walked past Sans and gave a wave in greeting, Frisk joining her in the action.

The next puzzle would have been challenging, if it actually worked. But after Pap gave a very long winded explanation of the complex puzzle, it turned out to be the easiest thing they came across. Unless you counted listening to that lengthy speech to be difficult, which Fay kind of did. Of course, once Pap saw the puzzle was broken, he sort of broke himself and just spun off. Not even bothering to hold back her laugh now, Fay burst into a fit of giggles.

"That was awesome. I wish I taped that. Youtube GOLD!"

Frisk just shook their head in amusement and the two went on, once again waving to Sans as they passed. This time he actually waved back, causing Fay to wave even more enthusiastically. Sans of course didn't match her enthusiasm and put his hands back in his pockets. Pouting a bit, Fay again shifted Frisk on her back and walked past another outpost. It would seem lesser dog was building a snow dog. Unable to help herself, Fay pet the guard dog and watched in amusement as its neck elongated. It now seemed to have been inspired and went off to make another snow dog. Pleased with herself, Fay skipped onwards with Frisk giggling on her back.

At the next puzzle, Fay grumbled. She couldn't exactly cheat her way out of this one. At least not while still coming off as human. Most humans couldn't jump the space between the cliff and the door. So with a sigh and almost practiced movements, Fay solved the puzzle on her first try. Though she was pouting and slouching the whole time. Stomping across the bridge, Fay ignored the slight look of amusement on Frisk's face. They were finally approaching the last FUCKING puzzle. Rolling her eyes, Fay looked to Frisk.

"Can we skip going to see Gyftrot? I just wanna get this over with."

Frisk looks at Fay and nods to her request. They too were getting rather tired, despite being carried pretty much the whole time. Frisk could only imagine how exhausted Fay was at this point. The two approached the bridge and quickly crossed, not really caring that the bridge was fake. As they neared the end, they could see Pap and Sans waiting for them. Stopping, Fay looked at the two skeletons and waited.

"HUMAN! THIS IS YOUR FINAL AND MOST DANGEROUS CHALLENGE! BEHOLD! THE GAUNTLET OF DEADLY TERROR!"

Papyrus flipped a switch on a remote and various weapons suspended over the bridge. Putting down Frisk, Fay stood in front of the child protectively and eyed the weapons in wonder. They had a fucking flame thrower! Marveling at the size of each trap, Fay didn't realize Papyrus was talking until the weapons were put away. Apparently, Pap didn't feel like using that particular puzzle. Which was good considering it wasn't a puzzle at all, but a death trap. Fortunately, Fay managed to keep from pointing this out. Papyrus walked off and the coast was clear. Looking back down at Frisk, Fay smiled and offered her hand. Frisk took it and the two finally crossed the bridge. Before entering the town of Snowdin, Fay looked to Sans.

"We could have been dead where we stood~ Heh! Knock knock!"

San's eyes narrowed, he felt he heard that saying before. Or perhaps said something similar? But when? Something was definitely up, and Sans wasn't going to look the other way this time. Despite being suspicious of the girl, Sans couldn't leave a knock knock joke unanswered. So with a wary huff, Sans played along.

"who's there?"

"DISHES!"

Again, if it was even possible, Sans' eyes widened. He knew this joke. He told this joke. In a place no one should have been. Sans knew this wasn't the woman behind the door. So how did little Fairy know this? Was it a coincidence?

"d-dishes who?"

"Dishes a BAD joke! Hehehehe~"

But Sans didn't laugh. He just stared at Fay in shock. It had to be a coincidence. But he knew better. He knew very well those didn't exist. Clenching his fists, Sans watched as Fay pouted and mumbled something that made him freeze. She then walked off with Frisk in tow. She was smiling, being completely harmless and innocent. She never even attacked a single monster. Yet she gave Sans the worst feeling. She only muttered a simple line, but it ran shivers down the skeleton's back. She said...

"Are you having a bad time?"

Sans almost didn't catch the fact that the kid had hit Fay in irritation and started to scold her. What did these humans know? Even the kid... He had to go check something. NOW...
