~Percy~

Despite the jarring situation, Percy was… excited.

At first, Percy was terrified, as any normal child should be. He would've had a panic attack if he didn't have his notebook. A lot of people didn't know about his… conditions. They always thought it was weird how he was so attached to his notes. They didn't understand that without them… Percy just couldn't budge. Lonely. Afraid. They were his only coping method. And the more afraid he felt, the more excessively he took notes.

Percy couldn't stand the thought of having a breakdown in front of his friends. People glowering over him, prodding him like an insect.

But now, the kids had motivation. They were trying to stop the Fallen Angel - who wasn't much of an angel after all. Percy suggested they get research about the Angel - and Faye seemed to know a place.

She'd heard about it while she was working at the snail farm. It was some junk sale run by an old monster. The monster who ran it supposedly knew a lot about history. Percy just couldn't stop twitching. Research and anime made him so giddy.

Faye had overheard some of their conversation, so she knew what was going on. Percy enjoyed Faye's company, even though he found her kind of weird sometimes. But she was quiet, and he respected that.

"We're gonna get 'em." Clover muttered darkly.

The kids were following Frisk. They were going to a store surrounded by a wooden border.

Percy gazed at Clover, clutching his precious notebook. She was pretty scary, but… so pretty. Wait what?

Percy scrapped his doodle of Clover from his book. He eyed her brother Cody next to her. Percy respected Cody, too. He was nice. And he respected Percy's boundaries. Percy liked anyone that respected his boundaries.

"How long is this research crap gonna take?" Brayden asked, pouting.

Percy didn't like Brayden at all when they first met. He was loud, annoying, didn't give a dang about personal space and made Percy feel weird about his formerly long-ish hair and anime/manga obsession.

But above all, he had been ruining Percy's friendship with Melody - his only friend. The bitterness still lingered.

"We can't just run into battle, Brayden." Melody snorted.

Percy and Melody had known each other since forever; they were practically family. They'd been through a lot together, and not just in the Underground. As long as Melody was there… Percy felt optimistic about the future.

"Let's just go in, y'all." Clover said. The children entered the store.

Percy stood next to Frisk. He had been a little unsure about them until he found out why they were here. They were here to save the world. Percy now had a lot more respect for them. He still thought they were kind of weird, though. There was this feeling that'd been surrounding them…

"Woah there!" a voice called out. "I've got some neak junk for sale."

It belonged to a tortoise monster with a white beard, wrinkled skin and an adventurer's hat. He was holding a microscope.

"Whoa!" Brayden exclaimed. "It's a turtle!"

"Tortoise." Percy corrected.

"Whatever," Brayden waved a hand.

Clover turned to the tortoise monster.

"Tell us everythin' you know about the Fallen Child, turtle." she said, giving the tortoise the Fallen Child poster.

"Tortoise." Percy corrected. He had his pen and paper ready.

"Shut up, Perce," Clover mumbled.

Percy felt a pain in his heart. He nearly fell over.

"Clover!" Melody scolded, grabbing onto her best friend.

"You'll find my name's Gerson," the tortoise chuckled. He eyed the poster. "Well well well. I don't find it surprising you seven wanna know about the only other fallen human! How'd you seven fall down 'ere, anyway?"

Faye began, "Well-"

"Not now," Clover interrupted. She banged her fist on her palm. "Speak, Gerson."

"Clover, this isn't an interrogation," Melody scoffed.

"This was YOUR idea!" Clover grumbled. She'd dropped her mock-cowboy accent. Percy had a feeling she was very serious.

"Clover," Cody crossed his arms. "Chill out, okay? How many times do I have to tell you that yelling's not going to help?"

Clover muttered a curse under her breath. Percy eyed Frisk. They looked… thoughtful.

"Well, if you kids are done arguing…" Gerson took a deep breath. "I'll tell you what I know. This human fell down a while ago. They lived with the royals, I believe. They loved monsters. They loved us so much they got their SOUL absorbed by another monster and went to the surface to find SOULs to break the barrier. But their plan failed. They came back Underground to die. But before they died, they promised they'd come to life again someday and free us all."

"But they ain't doin that…" Clover grumbled.

"And we already know all that crap!" Brayden complained.

"They became bad," Frisk spoke up. "Isn't it because of their hatred of humanity? They turned on us."

Percy grimaced. He had taken as many notes as he could. But he wanted to find out everything about the Fallen Angel. He would be able to defeat them.

"I've got no idea, kiddo," Gerson chuckled. "Everything about that human is a complete mystery. Wa ha ha!"

Clover looked thoughtful. "They must've tried to hide themselves and all their info…"

"Exactly," Frisk nodded.

"What a freaking COWARD!" Brayden yelled, stamping the ground.

Percy took more notes. This was looking very, very interesting…

"They're not a coward," Gerson said, looking confused. "They're the opposite! A hero. I dunno what you kids are talking about."

"They've tricked everyone." Melody scoffed in disgust.

"Thank you for your help, Mr. Gerson," Cody said politely. He held out some gold. "And I'll take some of those crab apples, please."

The kids left the store. They were headed right. Percy walked next to Frisk.

"I have lots of questions, much like our accomplices," Percy said, holding out his notebook.

"Fire," Frisk told him.

"Why didn't the first human destroy the world when they were alive and instead waited for us?" Percy asked.

"... they need DETERMINATION," Frisk said. "The power to live, the power to continue onward despite everything else."

"DETERMINATION is a powerful force," Percy noted. "But how exactly does it work?" He paused. "How do you plan on stopping the Fallen Angel?"

"Determination," Frisk replied. "We'll turn it against them."

"I see," Percy replied. "They will rise when we get past ASGORE. They will try to take our determination. But we won't let them. Instead, we'll use our determination…" He paused, gazing over his notebook. "We'll use our determination to erase them from every timeline. They will no longer exist."

"Whoa," Frisk raised their brow. "You've really been thinking about this, huh?"

Percy stared at them. "Is my plan possible?"

Frisk made a face. Then they nodded.

"Confusing, but as long as we have more determination, we should be good," Frisk told him.

The two continued walking, finding some more signs.

"Hurt, beaten, and fearful for our lives, we surrendered to the humans," Percy read a sign on the wall. He opened his notebook. He had different sections for all the many things in the Underground. "Seven of their greatest magicians sealed us underground with a magic spell. Anything can enter through the seal, but only beings with a powerful SOUL can leave."

"Like us?" Cody asked.

"Exactly," Percy replied. "We are incredibly powerful."

They kids crossed some waterfalls. Beside them were echo flowers, glowing in dark patches.

Percy read some more signs. "There is only one way to reverse this spell. If a huge spell, equivalent to seven human SOULs, attacks the barrier… it will be destroyed." He almost made a face. "The Fallen Angel must know about this. Seven is some kind of sacred number. They want to use our seven SOULs to destroy the world."

"Seven's a lucky number." Clover commented.

"Your name is Clover," Percy replied. "And four-leaf clovers are said to be lucky. So… maybe you are lucky too."

"Aww, thanks pardner." Clover said, giving Percy a noogie. He held onto his glasses.

She touched me...

"WATER!" Brayden yelled. He was swimming in some water connected to a waterfall. Little shiny sparks were flying around his head.

"We are not having another water fight!" Melody yelled, crossing her arms.

Percy walked through the water and approached another sign. He adjusted his glasses. They were hard to read.

"But this cursed place has no entrances or exits," he read. "There is no way a human could come here. We will remain trapped down here forever."

"But humans came anyway." Faye commented, biting her lip.

"So they did," Percy said. He observed his pen. It was purple, his favourite colour. "We should call Papyrus. It's unlikely, but he may know something about the Fallen Angel."

"Sounds good!" Frisk nodded.

"How many freaking people do we have to talk to?!" Brayden whined.

Percy was fascinated by Sans and Papyrus. They were living skeletons for goodness' sake. He wanted to know everything about them, but Sans didn't answer any of his questions and Papyrus didn't really understand. So Percy was ticked off. He hoped Papyrus would answer his Chara questions.

Before anyone could call anyone, however, the kids found themselves in combat with Special Enemy Temmie. She was a cat-like creature with a mop of black hair, the most fabulous face you will ever see ever, and dog-ears.

"Is she a cat?" Brayden asked. Or a dog?"

"I dunno what she is." Clover commented, raising her brow.

"I think she's adorable…" Faye commented, smiling.

Cody nodded in agreement.

"awwAwa cute!" Temmie exclaimed in the worst grammar Percy had ever seen. "(pets u all)" She extended a long white paw.

Frisk began sniffling and took a few steps back. "Allergies…"

"Hi, Temmie!" Faye waved at Temmie.

"Hello!" Cody greeted, sounding cheerful.

"HEY!" Brayden yelled, waving.

"That's not how you greet people, Brayden!" Melody exclaimed, glaring at him.

"hOI!" Temmie squealed. "i'm TEMMIE!"

A four-legged being with Temmie's face on it attacked the kids. Despite Frisk's allergies, the kids managed to get away scot free.

The children came to an area that was completely black, aside from a glowing path. There were glowing pillars with plants on top. It was even prettier than the other places. Squeaky mushrooms were alighting the paths. Percy realized this was all a puzzle. He got very giddy.

On the way, they ran into Moldsmal and Moldbygg. Percy could relate to Moldbygg on a personal level. He hated it when people entered his personal space. The children also dialed Papyrus.

"WHAT? MUSHROOMS?" he asked. "CAN YOU EAT THEM?!"

"I've heard eating wild mushrooms is dangerous." Cody commented, tapping his chin.

"It is," Percy replied. "Wild mushrooms tend to be toxic."

"WHAT?!" Papyrus asked, sounding astonished. "ARE YOU SURE YOU CAN'T EAT THEM?!"

"Nope." Percy replied.

"Pretty weird lookin' anyway…" Clover said, eyeing the mushrooms. She shook her head. "Papyrus. We gotta ask ya somethin'. D'ya know anything about the Fallen Angel?"

"AN ANGEL FELL DOWN?" Papyrus asked. "WHERE?"

"I was expecting an answer like that," Melody snorted.

"HOLD ON!" Papyrus yelled. "I THINK UNDYNE SAID SOMETHING ABOUT A FALLEN ANGEL!"

"What did she say, Papyrus?" Cody asked, looking excited. Everyone was staring at the phone.

"SHE SAID SHE WAS GOING TO HELP THE ANGEL RISE OR SOMETHING LIKE THAT," Papyrus responded. "BY HUNTING DOWN ALL OF YOU! NYEH! HOW ADORABLE! UNDYNE WANTS TO SAVE AN ANGEL!" He laughed nervously. "EVEN IF IT MEANS HUNTING DOWN ALL OF YOU…" He paused. "WELL, ENJOY THE MUSHROOMS!" He hung up.

"So we need to speak to Undyne next." Clover said, folding her arms.

"YEAH! WE GET TO FIGHT UNDYNE!" Brayden cheered. Everyone stared at him. "WHAT! I WANNA KICK HER FISHY BUTT!"

Percy was nervous. Undyne had done some real damage. She was dangerous, and Percy didn't like the odds. Then again, Frisk was on his side, and there was no one tougher than them.

"What the heck is this?!" Brayden asked.

The kids had entered a blue village full of Temmies. Percy had seen weirder anime, but somehow he was still surprised. Temmies were hanging around on the floor, being cute. Faye and Cody were cooing over them. They got to pat a few of them. Clover and Frisk went to the 'tem shop'.

"hOI!" Percy read the sign with no enthusiasm. "welcom to… TEM VILLAGE!"

"This is the weirdest place I've ever been to," Melody scoffed. She gazed at Percy. "I thought that manga you showed me, JoJo's Bizarre Adventure or whatever it's called was weird. But this?"

"JoJo is still weirder, honestly," Percy admitted.

"Okay, these guys are kind of cute…" Brayden said, grinning at the Temmies. He made a face. "I'm GONNA PICK ONE UP!"

"awwU!" the tem exclaimed in Brayden's arms. "humans… such a… CUTE!" She made a face. "bUT this one smells like sweatsss! tem no like SWEattss!"

She jumped out of his hands with a look of disgust.

"Wh…" Brayden sat there for a few moments. "I'M NOT SWEATY!"

"Yes, you are," Melody replied, crossing her arms.

"Am not!" Brayden yelled, storming over to her.

"Are too." Melody replied, glaring at him.

"Am NOT!" Brayden yelled, looking ticked off.

"Are too!" Melody said, narrowing her eyes.

"Guys!" Cody ran over, holding a Temmie. "Don't fight! It doesn't matter anyway."

"Oh, OF COURSE they love YOU, Cody!" Brayden grumbled. "Everyone loves you!"

"Maybe they'd like you too if you didn't yell so much," Cody mumbled, turning away.

Percy left them alone and went to see what was happening with Frisk and Clover. He passed Faye on the way. She was telling stories about human life to a bunch of Temmies. She waved at him. He nodded back. Then he entered the Tem Shop. However, Frisk and Clover were just leaving.

They had a ton of money and something called 'temy ARMOUR!' with them.

"What's all that?" Percy asked, raising his brow.

"We did some bargainin'," Clover answered. "We bought some… 'Temmie Armour'… it's really strong, supposedly. It was also stupid expensive."

"If we're gonna fight the Fallen Angel, we'll need it," Frisk said. "Also, remember the Dog Residue?"

"Oh, yes," Percy said, frowning. "The little white dog took the artifact then gave some to us. I remember."

"Yeah," Clover said, frowning. "Frisk filled up their inventory with it and sold a bunch to the tems. I helped out a little. We made a ton of money."

"I see," Percy said. "You have great business accruement."

"Listen, when you need money, you gotta go and get it," Frisk shrugged.

"Let's get outta here," Clover said, making a face. "We've gotta go fight Undyne, right? And also, this place gives me the creeps."

The three kids walked over to the others... but something funny had happened.

Faye was hugging an angry and very confused Brayden. Melody was protecting her face from Braydens hands. Cody was sitting on the ground, smiling nervously. They were covered in Temmies. It was like a cloud made of Temmie madness.

"You leave for three seconds and that happens." Percy mumbled.

"What in tarnation is going on?" Clover asked, staring at the four.

Frisk started to giggle, before bursting out in laughter.

Clover raised her brow. Brayden started laughing as well. So did Cody. Clover joined in, snortling. Faye giggled into her hand. Some of the tems started as well. Percy and Melody stared at each other, the latter sighing.

The kids left Temmie Village. They left the glowing mushroom area and headed right. They came to another dark room full of crystals. It was even prettier.

"Without candles or magic to guide them, the monsters used crystals to navigate." Percy read a sign. He was liking all this lore.

"What's this?" Frisk touched a blue lantern.

The path lit up. Everyone gasped.

"That's so cool!" Cody admired.

"Even though it's still so dark." Melody grumbled, observing the environment.

The kids continued, encountering a few more monsters, including one called Woshua. Woshua gave the children another clean.

"HA! NOW I'M DEFINITELY NOT SWEATY!" Brayden yelled, blowing a raspberry at Melody.

"You'll get sweaty again sooner or later." she replied.

After the battle concluded, the kids kept following the path. Since Frisk knew the way, it was very quick. The children came to a very dark area with only a mere waterfall. They trudged through the water. Brayden splashed everyone again. Percy stepped away. Doing fun activities like water-fights stressed him out.

Luckily, it was too dark so no one knew what they were doing. They got to the end of the room, where there was an echo flower.

"I don't have any good feelings 'bout this." Clover commented, furrowing her brow.

Brayden held up his fists. "Hmm…"

"I hope it's not the Fallen Angel." Melody commented, making a face.

"Fallen Angel won't come until we get to ASGORE, right?" Faye asked, staring at Percy.

"Correct," he replied.

"Guys, don't worry, it'll be fine," Frisk waved their hands. "We just have to…"

"Behind you." the echo flower spoke.

Undyne was there, a mad glare in her eyes. She stepped forward, her heavy armour crashing against the ground.

"YEAH!" Brayden cheered. "LET'S FIGHT, FISH-"

"Watch out!" Frisk dragged him out of the way of her spear.

"Seven." Undyne spat. "Seven human souls. Seven human souls… with the power of seven human souls, the Fallen Angel will rise. With that power, the Fallen Angel will shatter the barrier. They will finally take back the Surface from humanity… and give them back the pain and suffering we have endured."

"That's not their plan." Clover interrupted, crossing her arms.

"Yeah, they wanna kill everyone!" Brayden added.

"They're terrible." Melody agreed.

"They will destroy every timeline in existence." Percy said, clutching his notebook.

"SHUT UP!" Undyne yelled, sounding enraged. "You humans don't understand anything!"

"You're the one who doesn't understand anything, you idiot!" Melody crossed her arms.

"YEAH, MELODY!" Brayden cheered. "SHOW HER WHO'S BOSS!"

"Uh, guys!" Cody squeaked.

Undyne was gripping a glowing spear. She was aiming it at the kids.

"I'll show you who's boss!" she yelled, racing forward with her spear.

"Brace y'allselves." Clover said, grabbing her pistol.

However, Monster Kid got in the way. It turns out they were hiding in some sea grass.

"Yo!" they squeaked. "You guys did it! Undyne is RIGHT in front of you! You've got front row seats to her fight!" They looked around. They sounded confused. "... wait. Who's she fighting?" Undyne grabbed Monster Kid's cheek and dragged them away. "H-hey! You aren't gonna tell my parents about this, are you?"

The human kids looked at each other.

"Well… that was interesting." Cody chuckled anxiously.

"I think we're in for a bad time." Faye mumbled, looking down.
