"Dear 'boss' Monsters of the underground,

We cannot express our gratitude for the alliance and unity between monsters and humankind since the barrier from Mt. Ebott had been lifted. Your scientist, Dr. Alphys, has been more than willing to work with our best and brightest humans throughout earth for a once- in- a lifetime expedition to Mars and our two moons: Phobos and Deimos. Dr. Alphys and our top scientists worked together non- stop to research a new scientific breakthrough that would evolve the relations between humans and monsters. Politicians and scientists across the world looked on as Alphys excelled in her scientific fields, propelling our top scientists to unearth this new discovery.

In this, we are more than pleased to invite all of the 'boss' monsters to join this celebratory moment with the rest of the world leaders as we announce our newest breakthrough in physics and energy production. We feel as though the world leaders shall unite under science and technology, and our discovery shall solidify our union between humankind and monsters. Our company shall accommodate you with our finest space cruisers, a week's stay in our visitor facilities, and paid compensation throughout your travels.

It is a once- in- a- lifetime event for you and your people, and it is imperative that you all attend this event. Dr. Alphys has become a crown jewel in our scientific division and we are honored to have her work with us in our greatest achievement of both human and monsterkind.

With great regards,

Dr. Samuel Hayden,

Leader of the UAC Mars Facility"

"SPACE!" Papyrus shouted as he waited in line with Undyne, Sans, Toriel, and Frisk. "I CAN'T BELIEVE I AM GOING INTO SPACE!"

"Calm down, Papyrus!" Undyne shouted. "You're freaking the humans out over here!"

The line to the massive ship stretched to four football fields, despite multiple lines of people embarking onto the spaceship with bags and briefcases in hand. It was high noon, the weather was fair and the sky was clear with no clouds nearby. The massive ship itself sat in a plane of concrete, asphalt and steel, surrounded by tall grass and a massive hangar, housing state- of- the- art fighter jets, helicopters, and smaller space ships. This ship in which massive amounts of people were lining up to was shaped almost like an over-inflated football, with protruding dish-like appendages on the lower hull while the thrusters on the back were as massive as a three story house. Security guards surround the ship, vigilantly keeping watch over anything suspicious, all wearing black security armor and wielding high powered shotguns. Toriel looked on in awe at the massive ship and the humans guarding it.

"A lot has changed since we were underground." She said as she looked at Sans. "I cannot recall humans building something as large as this before."

"I guess not…" He said, shrugging, then looking at Frisk. "Though… space… have ya been to space, Frisk?"

"No… not really…" Frisk said, shaking his head. "I have only seen pictures of space when I was in science class."

Papyrus could barely hold in his excitement as he shifted left and right, almost like he could barely stand. The other humans looked at Papyrus, gawking at his excitement. Some children that were accompanying their parents chuckled, pointing at the large skeleton while the parents looked on at the weird couple. However, Papyrus was unfazed, eager to step into the ship and live out his own wildest dreams.

"I CAN'T WAIT!" Papyrus said as he looked up into the massive ship. "WE GET TO FLY INTO THE STARS! MAYBE EVEN VISIT OTHER WORLDS!"

"Speaking of other worlds…" Sans said, rubbing his skeletal chin. "Wonder how Alphys is doing on Mars. Seems like quite a damn step for a monster to travel through friggen space."

Undyne turned to Sans as she was done eyeing at the Security guards stationed at the checkpoints. She had talked with Alphys using a special cell phone the UAC developed to connect to the Mars station, millions of miles away. Even though Alphys assured Undyne that everything was going extremely well for her, the blue fish monster couldn't shake this doubt in her mind. The scientists talked about how Alphys constantly worries about oxygen leakage and suffocation, so she constantly wore an oxygen mask for the first few days of the ship. However, she was extremely glad that she'd get to reunite with Alphys after weeks up on Mars. Alphys herself even assured Undyne that she got used to the Martian and Phobos labs.

"She's doing fine, Sans." She said as the group moved up, getting closer to the space ship. "I have talked to her before we arrived. She's inviting us with the scientists to a party once we arrive on mars. Heh… she's probably having a blast right now."

"Shame that Asgore didn't come with us." Sans said, looking up at Toriel. "It would be fun seeing that big fuzzy guy in a space suit."

Toriel chuckled a bit but shook her head as she walked up to the checkpoint, closing into the entrance to the ship. She wanted the entire group to partake in this trip, but she knew Asgore had political work that required his undivided attention. Things would get awkward for the two goat monsters to be in space, anyway. It was best that Asgore remained on earth to continue easing relations between humans and monsters.

"It's probably best that he didn't come." She said. "I don't think the 'king' would do a good job if he were to be absent for a week."

"We'll give Asgore a gift from Mars!" Frisk said, looking up at Toriel with a smile. "Maybe some pictures, too!"

Soon, the guards looked at the monsters, gawking at them a bit under their large helmets, but then giving out their hands, wanting the group to show their tickets. She and the rest of the gang dug into their pockets and brought out tickets, which was a microchip-like card that the guards had scanned. The cards themselves were quite bulky, with readers on the front and the bottom of the key-card. However, they are able to fit inside pants pockets. After giving the group the green light, they stepped onto the ship, when papyrus was busy touching the hull. Undyne grumbled a bit.

"PAPYRUS!" She yelled. "Let's go! We can't hold up that long line!"

"Oh!" Papyrus said, nervously as he stood still for a moment. "Sorry about that! I was just admiring the steel of this ship! Quite marvelous, I might add!"

"Hurry up, Paps." Sans said, looking at Papyrus. "Don't you want to see the stars when this ship launches?"

Papyrus gasped a bit and ran with Sans to find their respected rooms. Toriel walked with Frisk up the platforms to find an elaborate area filled with shops, rooms and people flowing in and out of them. This area of the ship spanned for twelve stories, consisting of many bridges, walkways, and platforms for people to travel around. Scientists, Soldiers, and civilians all were moving to and fro, almost like a busy cityscape. Toriel could only look at it in awe, as it reminded her of the MTT hotel that was next to the core of the underground.

"Wow… I never knew they have this inside their space ship…" She said, smiling a bit. "Though, we should find our rooms. We can start exploring later."

Undyne grinned and crossed her arms, looking at Toriel and Frisk.

"You two go on ahead." She said, then walking towards the shops on the lower floors. "I'm going to see if they sell any anime so I can get something for Alphys!"

"Take care, Undyne!" Frisk said with a smile. "We'll meet you back in our rooms!"

Undyne winked and waved at the two as she walked off, looking for an anime store in the ship. Toriel then lead Frisk to a series of staircases and hallways, both of them eyeing at Soldiers and scientists conversing with one another, venturing to the specific rooms displayed on their keycards. S-24 was their respected room which was far from the other rooms they went by.

"Well then!" Toriel said cheerfully as she looked at Frisk. "Let us see what the UAC has in store for us! It's almost like when I showed you your room back in the ruins of the underground! Feels quite exciting, I'd say!"

"Yeah!" Frisk said with excitement as well. "I can't wait!"

As Toriel swiped the keycard and opened the door, they were greeted to a large, lavish room with couches, tables, a miniature bar, a large telescreen, multiple bedrooms, and a large window with telescopes before it. Both Frisk and Toriel were amazed at the room. Marble tiles laid across the floors with beautiful and elaborate rugs covering the living area to bring an inviting presence within the suite. Gold railings decorated the staircase, leading up to other rooms with beds. To Toriel, this was MUCH larger than her house in the ruins.

"Oh my…" She said as she walked up and touched the soft, red, velvet couches. "I didn't know the UAC were that generous… this is amazing!"

"They even have a fishtank!" Frisk said, looking at the aquarium with a lot of elaborate species of fish. "I wonder where are Sans and Papyrus?"

Both Toriel and Frisk jumped when they heard the trombone playing. They both turned to see Sans shrugging while holding his trombone up.

"Hey Tori… frisk." He said with a wink. "I guess you two were fetching for a bone?"

Toriel and Frisk chuckled a bit and saw Papyrus in the distance, holding a cart full of dishes.

"If you don't mind me asking… where did Papyrus run off to?" She said.

Papyrus then held out plates of spaghetti and set them on the tables nearby, winking at the rest of the gang.

"I got you all spaghetti, for we are about to embark on an adventure of a lifetime!" Papyrus said, posing dramatically with his scarf blowing in the draft for some reason. "I, the great Papyrus shall provide you with the food necessary to carry out our journey to other worlds!"

Sans shrugged and looked at Toriel.

"Looks like we're in for the long haul." He said. "Though, let's eat. I don't want to have Papyrus's 'great' creations run cold."

Suddenly, Undyne crashed into the room with piles of gifts and presents scattered all over the floor. A lot of the group was surprised that she was able to lift all of these, let alone make it through the doorway.

"Well?!" She said, stumbling and spilling some anime DVD's. "Are you going to help me bring these in?!"

Sans sat in front of the large window as the ship was in mid- flight. Stars filled the entire window, littering the darkened room with the beauty of the never-ending universe. It was like heaven for Sans, feeling completely at peace as clusters and stars filled the entire window. His boney fingers touched the window, looking on into the distance. However… despite all of this beauty… a feeling of dread washed over him. It felt like something incredibly sinister was among him and they were foolishly heading towards this danger.

"I'm… thinking way too hard on this…" Sans said to himself as he looked back at the group, sleeping soundly. "I should sleep anyway…"

Somehow, though… he couldn't… something dreadful in his gut was twisting inside him. It wasn't Papyrus's cooking that made him feel uneasy… but it was something else. Sans then quietly left the room… traveling through less crowded corridors to find this source of dread. Something has a lot of EXP and LV… The sheer determination and power beats at his mind. It couldn't be Chara... since there was no way even killing ALL of the monsters would garner such massive EXP and LV. With sweat dripping from his skull, he looked around, scanning his surroundings, following the massive power of determination.

"Where are you, 'human'?" He thought to himself. "I have some unfinished business..."

As he made it into the military wing, he could see soldiers stationed in every corner of alleyways and stairwells. Scanning his eyes at the soldiers, he could get a good grasp on how much EXP and LV they have. Given that they're soldiers, they are quite high. However, he couldn't really put anything past them. These soldiers follow orders, much like what Undyne does following Asgore's orders. Besides, he knew fully well that humans fight other humans for different reasons, so he doesn't mind too much, just as long as they don't cause a massive genocide. What his mind is really on… is one specific individual.

Target: The Doom Slayer

ATK: 99999 DEF: 99999 EXP: 99999 LV: 99999

"How the hell could a human have THAT much EXP and LV?" He thought to himself as he walked down the military wing, leading up to some narrow corridors. "This guy… makes Chara look like a saint…"

Sans NEVER met ANY human like this before… and a thought of meeting him or her sends shivers down his skeletal spine. It was like the Human had been killing things like it's been getting out of style. One would question how many has this human killed, exactly… but Sans knew for certain that this one had killed too many to even fathom. As he went down further to see where this human may be hiding, he was hindered by one massive door with a neon sign above it reading,

"RESTRICTED AREA: AUTHORIZED PERSONNEL ONLY."

Soon, some of the guards saw Sans nearing an extremely classified area of the ship, which caused two of them to walk right in front of sans, gripping their rifles tightly. Both of them seemed to have brown, buzzcut hair, wearing black security armor. Both rifles that the security guards were holding were high powered plasma rifles able to cut through solid metal. However, Sans checked the EXP and LV of the two guards… hopefully they won't try anything rash. Clearly, their EXP and LV pales in comparison to what's behind that door.

"Hey, bonehead." One said. "What the hell do you think you're doing here? This place is for authorized UAC personnel only."

"Just admiring that red sign…" Sans says, pointing at the neon sign above the door. "It takes up a lot of my time… wanna see it with me?"

Both of the guards gawked a bit but then shook their heads. As they shouldered their rifles, one specific individual walked in between the guards. This person had green armor, a bald, shaven head and some badges that were fastened on his chest… signaling that he was an officer. He went in between the guards and raised one of his hands at the two.

"At ease, gentlemen…" He said, seeing the guards separate and walk away. "Sorry about that, Sans. They take their jobs a bit too seriously."

"I think these guys just need a bit of a nap." Sans said, shrugging and winking at the officer. "They seem to be workin to the bone."

"Heh, I guess they were… but they have a job to do anyway…" The officer said, holding out his hand. "My name is Sergeant Marcus Kelly. I oversee the UAC security on Mars."

"Nice to meet ya, Kelly." He said, taking his hand, then emitting a long fart sound, winking at the officer. "You seem to be holdin' this place up pretty well."

Sergeant Kelly then raised an eyebrow and looked at Sans, already pulling out a whoopee cushion and showing it in front of the officer. Sans then shrugged and winked at Kelly.

"Whoopee cushion in the hand trick." Sans said as he threw it aside. "Gets em' everytime…"

Seargent Kelly chuckled at Sans's joke as it did lighten the situation a bit. Sure, he had to take his job seriously, but Sans's personality was enough that he would let things slide… for now.

"I guess you got lost, taking a tour of the military wing?" He said. "The ship is quite big to get used to for now… but I think you will like our Mars and Phobos facilities."

"Meh… I'll find my way around…" He said, turning around and preparing to leave. "I keep an eyesocket around for any maps I find, anyway."

"Amusing…" Kelly said, rolling his eyes. "Just don't go wandering around places like these. The UAC doesn't really like security breaches."

Sans turns and looks back at Kelly with blackened eyes. His pupils disappeared, though still retaining that wide, skeletal grin. He may seem like a cute skeleton, but his expression seemed cold and foreboding. This threw Kelly by surprise, since he was getting used to the happy and prank- loving monster.

"I don't know what the UAC is hidin'…" He said, darkly. "But they better throw that thing out of the airlock. The sooner, the better."

"I'm afraid I can't do that, Sans…" Kelly said, eyeing at Sans coldly. "I'm under direct orders from the UAC to deliver all top secret objectives safely to mars... you could complain that to the UAC when we get there."

Sans paused for a moment and closed his eyes, not saying anything as he turned around and walked all the way back to his own room. He knew something was up and he would have to find a way to persuade them. Kelly didn't keep his eyes off of Sans until he left the military wing, knowing that Sans will do something to anger the UAC. As Sans walked through the hallway, he had eyed a shady looking man sitting alone on the bench between two stateroom doors. The man seemed to wear a black hooded poncho and seemed to be elderly, with cybernetics implanted in one of his temples. The hood covered most of his face, which gave Sans a foreboding feeling in his soul.

"Evil will rise…" The man said. "The Devil… was a murderer from the beginning, not holding to the truth… for there is no truth in him…"

Sans only darkened his eyes, stopping for a few moments and looking down. The feeling of dread intensifies as he could not fathom what he's stepping into. Even though he doesn't know what's going on, he felt like he has to know every detail. However, with the UAC constantly hiding everything, to the creepy vibes he is getting on this trip, he knows that the humans were hiding something… maybe something extremely sinister. Whatever it is, he couldn't rest until he finds it. Walking briskly towards his own room, he sat down on the bed, unable to sleep and continuously pondering. He has to know the human behind the massive EXP and LV.

"Come on, Alphys!" One scientist said, wearing a white lab coat, thick glasses and sporting a black, oiled hair. "I'm getting the popcorn ready! Let's watch another episode!"

Alphys was in another room, adjacent to the relaxation quarters of the Mars lab. Flourescent lights hang on the ceilings in each room with white paneled walls decorating the place. The commons is clean, organized and decorated with books, potted plants, DVD's and telescreens displaying either Mars weather patterns, oxygen levels, or just TV news. Alphys's own room had a bunk bed, with a large computer on top of a small desk, littered with anime DVD's, figurines, and ramen bowls. Alphys herself was just typing out a couple of messages to her friend, Undyne as she looked back out of the room.

"Just a minute!" She said. "I just gotta finish a few things first!"

"Well, don't keep us waiting!" A female scientist said in the distance. "I got the DVD ready! Mew mew ain't going to kiss some cuties without you around, girlfriend!"

Alphys giggled a bit as he walked out of her room, ready to watch anime with her two human friends. She looked at the male scientist with glasses… Dr. Jonathan Willits. He was one of the first humans she has met on Mars and he could remember Alphys being a great lab partner. The female scientist, whom sports brown braided hair, fair skin and blue eyes was none other than Dr. Andrea Tallman. She too was assigned to work with Dr. Alphys and they grew to like her extremely friendly personality. Even though Alphys was incredibly shy towards the two scientists, they knew deep down that she needed a friend, especially when being separated from her loved ones, Billions of miles away.

"S-sorry about that." Alphys said, stuttering a bit. "I just had to s-send a message to Undyne… that's all."

"Don't worry about it, Alphys!" Jonathan said, holding up a bucket of popcorn. "Got the popcorn ready! Let's watch some anime!"

"First, let me boot up the DVD player!" Andrea said, getting close to the telescreen and dusted the DVD player. "Good thing the UAC allows antiquated technology… we would have to watch sound of music for the thousandth time…"

Andrea wasn't kidding around. The UAC has a very strict policy for what could enter or exit the Mars facility. Very few movies could even be allowed to be played on the telescreen… however, serials and import movies seems to be okay in the eyes of the UAC. As the DVD player booted up, Alphys squealed in delight when the next episode of Mew Mew kissie Cutie appeared on the screen. Her fellow scientists chuckled a bit.

"So… did you get any calls from Undyne, yet?" Andrea said. "We already have everything set up for the party in a few days."

"Oh yeah!" Alphys said, looking at Andrea. "Undyne sent me a message from her phone! They're on their way over here!"

"Great!" Jonathan said, as the show began to start. "I can't wait to meet them!"

All of them hushed as the next episode of Mew Mew kissie cutie started. The scientists paid their undivided attention to the anime, since it literally beats watching restricted flicks. Silently enjoying the anime, Alphys barely held her excitement as she talked continuously about the plot of Mew Mew Kissie Cutie and how much better it was than mew mew kissie cutie 2.

"I mean… this version of Mew Mew has so much character to it!" Alphys said. "Don't you guys agree?"

"Well, yeah… sure." Jonathan said smiling at Alphys. "Though, let's watch this episode first."

Alphys chuckled a bit, but then frowned, feeling a bit anxious to tell her friends over what she was working on Phobos. It seems as though she desperately wants to tell them the potential dangers of mars. Unfortunately… she could eye the cameras all over the living quarters. The cameras zoomed into her harshly, constantly on watch for any sign of disobedience. He sighed and continue watching the anime, at least keeping her mind off of her being watched by the UAC. As the show ended, the two scientists turned to Alphys.

"So, are you guys ready to turn in your uh… research notes to the UAC?" Alphys said. "Dr. Olivia Pierce has been… well… bugging us about it quite a lot lately."

"Oh yeah, don't worry about it, Alphys." He said. "That cyborg will get all of our findings soon."

"Look on the bright side…" Andrea said, shrugging. "At least we will get massive amounts of fame and fortune after this discovery!"

"Yeah…" Alphys said, looking down. "Of course… Let's just hope that the other monsters appreciate the party."

"Of course they will!" Andrea said, setting her hand on Alphys's shoulder. "We got the food and drinks ready! I'll be getting some guys to cook some spaghetti for all of us!"

"Look… Alphys…" Jonathan said. "Everything will be fine! What's the worst that could happen, really?"

Alphys sighed and smiled, shaking her head. All she could think about was the party. She wanted to give her fellow monsters a good impression, since she hasn't seen her friends in months. It was her chance to finally give them a good impression after months of absence.

"Stomach aches from the spaghetti?" She said with a chuckle.

The two scientists chuckled heartedly.

"Maybe!" Jonathan said. "From the looks of it, Papyrus and undyne would set the kitchen on fire just by walking in there!"

"Oh… I will cook something…" Alphys said, chuckling. "Some ramen won't hurt at all!"

Alphys stretched and yawned a bit, rubbing her glasses and stretching her tail. After the show, she needed to get some sleep. Tomorrow will seem like an even busier day. As they all got up, Alphys walked into her room. Already, she frowned, looking unsure about tomorrow. Her "discovery" didn't seem to sit too well with her, but she is confident that she will impress both humans and monsters with her inventing prowess. However… something sinister was sitting in her mind… she laid in bed, but she couldn't sleep. She internally wanted to warn her friends… but somehow… UAC won't let her.
