In one world, this plan worked...and a single human would decide the fate of Chara and the monsters underground. Mercy, or Genocide?

However, in this world, this plan was stopped. Asgore will never declare war. Others do not fall for a long time... and a young woman will be followed by a SPARTAN super-soldier...

"So...Six human souls?" Asriel asked Chara, slightly upset at what his adopted sister would put herself through.

"With my soul, and the six other souls, we could break the barrier and free everyone!" Chara said. While she hated seeing her brother and best friend in pain, it had to be done. "We know that buttercups are poisonous, it will be a way for you to obtain my soul without killing me!"

"ABSOLUTELY NOT!" A horrified voice called out from the doorway, and Toriel stood there, plate of butterscotch-cinnamon pie dropping from her hands. She ran over and stared into Chara's brown eyes. "My child, do not even THINK of doing such a thing!"

"Mom...it is the only way of freeing everyone." Chara said, starting to tear up herself as Toriel started crying.

"You are our young angel, Chara. You are too precious to lose!" Toriel said, hugging her close, "I know the humans up there made you try to kill yourself...but you landed into our care! Gorey and I will NOT lose our daughter! Even at the cost of our freedom...we love you too much!"

"Mom!" Chara cried into Toriel's shoulder as Asriel hugged her from behind.

"Maybe...it's for the best if we move away from the barrier." Toriel said, looking up to Asgore who was coming into the room.

"I think you're right Tori." Asgore said, leaning down to comfort his crying family.

"It's so cold!" Chara said, holding her arms across her chest as the family shuffled through the snow.

"What do ya mean by that, Chara? It's nice!" Asriel said, flopping down to make a snow angel.

"I'm not covered in fur." Chara spat back, before sneezing loudly.

"So, Gorey, where is our guide? The one you said would show us around?" Toriel said, as Asgore looked around him.

"He said he would be right here." Asgore said, with Toriel narrowing her eyes at her.

"Heya." A voice said behind them, making the adults and Chara turn around with Asriel sitting up. Behind them stood a skeleton around Chara's age in a blue hoodie, black and white shorts, and pink slippers. White pupils stood out in his eye sockets, shining in joy. "So, I wasn't expecting to guide literal Royalty, but I guess I'll make do. I'm Sans. Sans the skeleton!"

"Greetings Sans, My name is Toriel. This is my husband Asgore, and our children Chara and Asriel." Sans tilted his head to get a better view of the children.

"Huh. I guess the rumors of the Royal family adopting a human were true!" Sans said, winking an eye socket at Chara. "Eh, follow me. I'll show you around Snowdin Town." With that, he started walking forward and lead the family past a sign saying "Welcome to Snowdin Town".

"Sans! Where have you been?!" A voice slightly younger than Chara said, as a small skeleton in an orange shirt and blue shorts with a red scarf and boots ran forward.

"Hey Papyrus, just showing the newcomers around town. I told you about that bro!" Sans said, a wide toothy grin seemingly stretching wider at the sight of his brother.

"You said you were going to help me with designing puzzles! That way I can be in the Royal Guard when I get older! Nyeh heh heh!" Papyrus whined.

"Hey bro, look who I'm showing around town." Sans said, winking towards the Royal family as Toriel covered her mouth to stifle her giggles at the excitable skeleton kid.

Papyrus stared at Sans, before sighing and looking behind his older brother. "OH MY GOD! THAT'S THE ROYAL FAMILY!"

"I know bro...As you see I'm getting a TON of work done...a Skele-TON." Sans said, making Toriel and Chara laugh at the horrible pun while Asriel and Asgore cringed slightly.

"SANS!" Papyrus shouted, embarrassed at the pun Sans made in front of Royalty.

"Come on, you're smiling bro." Sans said, pointing at Papyrus.

"I am...and I hate it." Papyrus huffed, crossing his arms.

"Why don't you ask dad for help while I'm busy? He IS the Royal Scientist after all!" Sans said, and Papyrus had this hyped look on his face before running off, scarf trailing in the wind behind him.

"Yeah...so you all met my little brother, Papyrus. He's excitable, so he has trouble making friends...but all the same, he's the thing I hold most precious so far in this world. His personality makes it...hard for him to make friends." Sans said, starting to walk along the path, "So he one day hopes to make a lot of friends by joining the Royal Guard. He means well, and he's not dangerous at all, even if he tries to be."

"He looks like a wonderful child, so cheerful." Toriel said, as Chara cautiously moved closer to the strange skeleton guiding them by holding onto her mom's hand.

"Yeah. He got beat up by some bullies the other day, and yet tried to defeat them by 'being nice'...I sometimes wish I could see the world through his eyes." Sans said with his eye sockets turning dark, before the white pupil reappeared, before turning to make eye contact with Chara. She stared at Sans, before he grinned even wider. "Hey, but if you to hear more jokes, I jot some real RIB ticklers!"

Chara and Toriel snorted while Asgore and Asriel shook their heads in exasperation.

"Are you sure this would work?" Toriel and Asgore asked.

"(By my calculations, monsters last centuries due to how much magic makes up their bodies. Humans have very little magic, making their lifespans shorter.)" W.D Gaster, Royal Scientist and father to Sans and Papyrus said as he stared at the teenage Chara, with a teenage Sans and Papyrus in the room. The skeleton brothers had gotten close to the Dreemurr family, to the point where Chara suddenly asked Sans to be her boyfriend.

This of course shocked the older sibling, as he hadn't thought of himself as 'dating material'. Still he accepted and this led to Papyrus getting a best friend in Asriel, becoming as close as brothers...even bonding in their annoyance at Sans' constant puns!

"(However, I do believe I can develop something to extend her lifespan...but it will draw a lot of magic from you two to sustain her. Is that alright?)" He asked, and Toriel grasped Asgore's hand.

"We will do whatever it takes." Asgore said. Gaster gave a widened grin with his cracked skull and immediately started sketching something on a piece of paper, obviously working on designing something.

Chara grasped Sans' hand as he looked down. "Hey, it's going to be alright!" She said, "W.D. Gaster is the Royal Scientist for a reason."

Sans sighed, "I know...but I can't help but worry for some reason."

As Gaster walked down a hallway to his lab with the design in his hand, he stopped to grab one other object...

A single, potted, golden flower...

Centuries Later...October 20th, 2552.

The Dreemur family walked along the ruins the two adults had moved out of years ago. This was a visit to reminisce and take a break from the cold Snowdin.

"Things sure are different." Sans said, walking alongside an adult Chara, who now had red eyes like Toriel and Asgore and a more prominent blush on her cheeks, "Dad falling into a machine, and my bro being in a part of the Royal Guard. Though the last part is to be expected."

"Naturally!" Papyrus explained, wearing his "Battle Body" with the Delta Rune on the left side, "As the bodyguard of the fluffy prince Asriel, I am NATURALLY part of the Royal Guard!" An adult Asriel rolled his eyes next to him.

"I don't have the heart to tell him that being the Royal Guard of Asriel isn't the kind of Royal Guard he was trying to get into." Sans whispered to Chara, who giggled slightly. This time, unlike the few others, they came across a strange sight.

(Halo Remix- When the World Ends by Spartan239 www. youtube watch?v=q6FLD-oyoDo )

7 Adult humans, wearing green body armor and helmets over green, black, and white camouflage clothing laid dead on the ground by the golden flowers, bodies and armor hit with scorches from some kind of weapon. MA5C Assault Rifles and magnum pistols laid on the ground by the bodies. In front of their eyes, over the bodies, floated 7 "hearts" making up their souls. There were two orange hearts, two light blue hearts, two purple hearts, and a blue heart. Asgore reached out and absorbed the Dark Blue soul, getting dark lines going down his cheeks and a trident marking on each hand. He floated upwards, the six other souls following him, and lashed at the barrier with all seven human souls, and a portion of his own. The seven souls flew into the barrier, and Asgore lost his form, reverting to normal and landing on the golden flower bed. The barrier cracked.

At this commotion, monsters started flocking to the ruins. First it was Undyne, the new Royal Scientist Alphys, and the Royal Guards 01 and 02, and the "Dog team" composed of Dogamy, Doggarisa, Lesser Dog, Greater Dog, and Doggo. Soon, more monsters approached the cracking barrier and to their eyes, watched it shatter like glass. When that happened, an earthquake shook the entire mountain, causing parts of the ruins to fall over or collapse.

"I can't believe it...we're free!" Undyne said, tapping a body of a soldier with the butt of an energy spear. There were whispers and mutters among the monsters as Chara, Asriel, and Sans started climbing up the ledge before Alphys pressed a button and a stairway to the top appeared from the wall of the chasm, making the trio look very embarrassed.

"We'll check out the surface before everyone emerges. We don't want to make a bad impression on our new neighbors!" Asgore said cheerfully to the gathered monsters.

"I can't believe I will finally meet the sun!" Papyrus said, shivering in excitement. As the group of monster moved up the stairs, nothing could prepare them for what they saw.

Clouds of dust clouded the sky. Gigantic purple and white spaceships with ovular fronts, rounded midsections, and an ovular back end with glowing blue engines in the back end struck at the city near Mt. Ebott with plasma lasers from the midsections. There were 6 foot tall creatures with leathery skin wearing tanks connected to gas masks with a purple pistol-like object with a glowing green section in the front (Plasma Pistol).

6 1/2 foot creatures with a long, birdlike body, toothy beaks, tufts of feathers at the top of their heads, and a blue energy shield in their left hands with a purple round device with pink crystals sticking out of it (Needler).

7-9 foot long creatures with leathery skin and fur with orange eyes wore gray, gold, or blue armor and were ape-like in appearance. Some held handgun-like objects with two sharp blades beneath them (Spiker), others held a rounded weapon with a short nozzle and a large curved blade on the bottom (Brute Shot), other had two red ovular structures parallel to each other (Brute Plasma Rifle), and another held gigantic hammers with a small blade on an end (Gravity Hammer).

"Sans...are any of those...humans?" Papyrus asked.

"No bro." Sans said, teleporting in front of Chara. A larger creature turned around and fired at Sans with the Brute Plasma Rifle, only for Sans to block the blasts by making bones protrude from the ground, "Whatever they are, they're obviously not friendly."

"Look up!" Undyne shouted, throwing energy spears at something. The group of monsters looked up to see one of the large purple ships over their position, midsection starting to glow red.

"I hate to say this after being freed, but maybe we should go back underground..." Asgore said, blasting at it with fire magic. Both the spears and fire were deflected by a blue energy field around the ship. A gray ship with two protruding engines and a crocodile-like snout flew down from orbit and started firing at it with glowing rounds from the front of it, causing the ground to shake with each shot.

"Move! Sans shouted, and everyone felt dizzy as the world spun around them. They reappeared at the doorway to the ruins with Sans unconscious.

"SANS!" Chara shouted, running to his side as she checked over him, "He's exhausted, he used too much energy teleporting everyone." She said, as Toriel knelt down to heal him.

"Is everyone accounted for?" Asgore asked, and the Royal Guard did a quick check to ensure everyone was there.

"Was it the humans?" Grillby asked quietly, seeing his favorite customer unconscious.

"No." Asgore said, "There were...other things attacking the humans, and then attacked us." This statement made the gathered monsters mutter.

Sans let out a groan as he sat up and looked around groggily. "Those things...I've never seen such high Levels of Violence!" He said, making Chara look at him in shock.

"They were level 20?" She asked.

"That was the lowest level...I saw ones over 100." Sans said, making Toriel bring her hands over her mouth as she gasped.

"So you Judged them?" Asgore said, "Did you get anything else besides the Level of Violence?"

"They are an alien alliance known as the Covenant. The large ones are Jiralhanae, the bird-like ones are Kig-Yar, and the ones with gas masks are Unggoy. Their goal will end up in the extermination of all life in this galaxy...and they were planning to betray another allied species known as Sangheili." Sans said, eye sockets dark.

"Those terrible creatures." Toriel said, staring at the still visible spaceship from the hole in Mt. Ebott. Then, it fired, a red hot plasma beam carving through the staircase like a knife through hot butter and shaking the ground upon impact.

"Run!" Undyne ordered, and the monsters ran into the Ruins as pillars in the front collapsed. Once inside, no one spoke. A bunny in a red shirt and blue jeans sighed sadly as she peered at the ruined staircase to the surface.

"We were free...than those things chased us back down..." She said sadly.

Unbeknownst to the monsters, a single golden flower sprouted from the ground with a sinister toothy grin with black eyes and white pupils by the ruined stairway.

October 20, 2558

"So you know the plan?" A gruff voice echoed through her ears. Frisk was young, a 15 year old orphan from the attack on 2552 who was scrounging around to care for her little 7 year old sister Lily. She knocked a can across the floor as she fled from the warehouse she was volunteering in for money. She didn't dare look back.

What she heard was dangerous, and others had been killed by that gang for lesser reasons.

After a few blocks of running, she came to a ran-down apartment, and ran up the stairs. She paused and saw her little sister sleeping on the only, ratty mattress in a threadbare blanket, her brown hair ruffled from turning in her sleep, a tattered teddy bear clutched in her arms. She quickly grabbed a backpack and threw their few clothes into it, before throwing their crackers , bread, and peanut butter into it and throwing it on her back. She picked up a little metal device and pressed it, a holographic screen of Frisk holding a one-year old Lily smiling with their parents at a beach popped up. Still glancing at the happy photo, she went to work writing down everything she heard before tucking the note into her left pocket.

Frisk smiled wistfully before turning the photo off and shoving it into her right pocket. She then picked up her little sister and wrapped her in the blanket and walked downstairs to the doorway, looking either way before running down a few blocks to a tall building with an eagle, wings spread, standing on a globe with the words "United Nations Space Command" on it. She nudged the door open with her back and cautiously moved inside; making sure not to let Lily hit anything. A woman in a business suit sat at a desk, as soldiers stood watching her.

Frisk was fearful at their gazes covered by orange glass, but the thought of getting that dangerous gang off the streets filled her with determination!

The woman looked down, eyes softening at the sight of the two kids.

"Hello little ones! Where are your parents?" She asked, and Frisk looked away.

"...They're dead..." She said, refusing to make eye contact.

"Oh I am SO SORRY!" The woman said, standing up from the desk to move around to Frisk and bent over to hug her. "But...something tells me that this is serious."

"I...I overheard some plans from the Epsilon (1) Gang when I was volunteering at a warehouse." Frisk said, making the woman gasp one of the soldiers to step behind her.

"Excuse me...did you say...The Epsilon Gang? The people wanted for Grand Theft Auto, Massacre, and armed robberies?" The soldier said with a firm, angry voice.

Frisk made a nod of confirmation, making the soldier reach up and touch a button on his helmet.

"Commander. We need a 10-59. Civilian lead of the possible Epsilon Gang. 10-35. Possible chance to 10-91?" He said, making Frisk confused at the terms.

(If you don't know, look them up here mistupid military/radiocode. htm )

There was a couple minutes of silence before a weary voice replied "Granted. Sending Spartan Headhunter Andrew."

"A Spartan..." The man whispered, and Frisk perked up. She had heard the rumors of the Spartans during the Human-Covenant War...who hadn't?! EVERYONE knew how Spartan Master Chief Petty-Officer Sierra One One Seven was pretty much a one-man army that got through impossible to survive missions.

"Any chance she was followed? There's suspicious vehicle activity outside the station." Another soldier said, and Frisk gasped.

"My sister! They may hurt my sister!" Frisk said, handing her sister over to the soldier behind her.

"Relax. We're on it." Another said, moving over to her.

"NO! I CAN'T LET THEM HURT MY SISTER!" Frisk shouted, pulling the crumpled note out of her pocket and handing it to the soldier, "Get this information to the authorities, quick! I wrote down everything I heard." When the soldier looked down at the note, she took off; running out of the door.

"It's her!" She heard the voice from the warehouse shout, and she ran harder than she ever did before, heading to a place she knew people never moved to in fear of the legends...Mt. Ebott.

A tall man about 6' 10" in height with short cropped brown hair stood on a circular device as robotic arms lifted armor over is legs, feet, waist, chest, shoulders, arms, and hands. He stepped off the machine and grabbed a helmet with a visor that looked dark gray. Snapping the helmet over his head, the visor lit up in the yellow Saturnine color. The Sage Green and Cyan Blue Mjolnir Gen 2 Wrath Anhur armor clunked heavily against the ground.

"So what's the mission?" A tenor, slightly growling voice said to a man as he faced the screen in front of him. The Spartan picked up a magnum that was painted a sand brown color with the logo and letters of the UNSC on it before it magnetically attached to his right thigh.

"As of 1400 hours, this civilian overheard plans of the dangerous Epsilon gang." The man said, as a picture of Frisk from their security cameras came on the screen. "Upon realizing that she may have been followed, this Frisk, no family name known, left a note detailing what she heard with a soldier and fled toward Mt. Ebott. We have Wasps following from the air, but we can't send large ground forces after her without alerting the gang and forcing them back underground."

Spartan Andrew nodded and pulled up a MA5D COG Assault Rifle painted green with the eyes and teeth of the "Sharktooth grin" famously painted on the spitfire planes of World War 2.

"Your job is to ensure the witnesses safety. We know the gang is chasing after her. Each member has a death sentence waiting for them so if possible, you are authorized to eliminate them. That is why we're sending you, a Spartan of the Headhunter division." The man said, as the Spartan rested the COG Assault Rifle on his back, where it magnetically locked in place.

"So basically, I'm a babysitter." He said, standing up, "But don't worry. The girl will be safe. I will eliminate all hostiles."

He stepped out of the office to see a soldier holding Lily, and paused momentarily to stare at the young child, the engraved Death's Head staring sightless at the kid. "So that's why she fled." He muttered quietly, running out the door as thrusters activated on the back of his armor and sent him running forward about 45 miles per hour.

(OST: Slingshot by Trocadero. Red Vs Blue Season 14 www. youtube watch?v=AHfuMHUBp14 )

After nearly an hour, he stopped in the forest, watching Frisk stop and pant for breath. Frisk jerked her head upwards as she heard a branch snap and headed further up Mt. Ebott.

"Dang that kid can run." A man said as he emerged from the vegetation. 4 other men and 3 women emerged from the vegetation with a variety of weapons across their clothing.

"My it's a family reunion...and I'm the party crasher." Andrew said, making the gang members look at the Spartan.

"It's eight on one. Do you think you can beat us?" The first man said.

"...I'll take those odds." Andrew said. His heart thumped loudly and the world seemed to slow down as he entered what was known as 'Spartan Time'.

A man grabbed a large hunting knife strapped to his leg and the Spartan was on him in a second with a quick blast of the back thrusters. He grabbed the gang member's hand and spun, lashing out with a kick that shattered the pistol of a woman nearby when his armored foot made contact with it. The man was pulled off his feet with the spin and then the Spartan swung his arm down, sending him crashing to the ground. Andrew turned the man's hand and pulled the knife out of the man's grip, only to slam the blade into his throat.

"I'll even make it fair...I won't use my guns." Andew said, making a 'bring it' motion with his left hand. A woman pulled a magnum out and fired at him, only for a glowing yellow energy to flare up around his armor as the bullets dropped off the armor's chest-plate; completely flattened. He charged forward and punched into the gun-woman's stomach and forced her to drop the magnum and he grabbed it and fired it once into the head of it's owner before throwing it into the face of another man and kicked the man with steel-shattering force in his left leg before jumping up and landing a punch with the same force into his skull.

"Down to five...still feel confident?" Andrew asked, heart thumping loudly in his ears. A nearby man grabbed a large machete he had and hefted it above his head, "Huh. You're making it too easy!" Andrew said, thrusting forward and sliding down with his leg out as he knocked the man off his feet and jumped up to grab the hand with the machete and swung it down into the man's chest.

The woman whose gun he shattered ran forward with a knife and the Spartan almost sighed at the predictability and grabbed her hand and stuck her own knife into her cheek and then punched it into her skull. As she dropped he charged forward and punched another man into a tree with steel-shattering force and activated his thrusters, grabbing the man and throwing him down to the ground. He jumped forward and smashed a knee into another man's chest and grabbed a knife strapped to his leg and threw it into the back of the last woman's leg. He kicked that man in the head and thrusted over to the woman, picking her up before throwing her head-first into the ground.

Seeing the last two men he seriously injured, he grabbed the kukiri knife strapped to his left chest and walked forward, stomping on the chest of the man he threw into the tree before walking forward to the man he kneed in the chest.

"No hard feelings." Andrew said, stabbing the kukiri into his throat before pulling it back, flicking off the excess blood before cleaning it on the man's jacket. Once it was clean, he re-sheathed the knife.

He took out a flare from his pouch on his left leg. "All threats neutralized...and that girl is still running. Better let the guys in the air know where the bodies are." With that, he lit the flare, throwing it near the bodies and watched the red smoke from it billow into the air before moving forward after Frisk.

He entered the mountain which had a gouge carved into it from a Covenant Plasma strike and saw the moved vines before walking to the hole, seeing the ruined stairway and utter darkness in the hole. He knew what happened...

Frisk fell into the hole.

"So this is the rumored entrance to the underground?" Andrew said, peering into it, "Old legends aren't going to make me fail my mission." He growled out, jumping down and activating multiple thrusters on his suit, slowing his fall as to not crush Frisk and move out of the way should she be right below him.

Spartan Headhunter 249008-0418AP was primed for duty.
