Hi everyone! This is something that many a person have done, but I will have my own twists. Also, I'm debating giving sans shotguns, like reapers from overwatch. No? Yes? Maybe? Stay to the plot you game ruining idiot? Please tell me. Right away I'm expecting lots of no, but I'm hoping that I will get proved wrong! The shotguns wont make sans overpowered anyway, and he needs a long ranged attack other than bones. He will get to tired to fast if all he can use is magic on waves upon waves of Grimm. Imagine him using his bone attacks times twenty because of all the Grimm! He will get tired twenty times faster, and it will be really easy for a Grimm to take him from behind without a backup weapon. Also, I don't own Overwatch (Need this one because I mentioned reaper, not beacause there will be overwatch characters in this story), RWBY, or Undertale, nor do I own any characters from them. Oh, yeah, and bold italic is the scary voice sans uses while saying things like "Youd be dead where you stand". Oh, and if the name sans has no caps, its on purpose. You know what I mean. Got it?Well, bye!

Sans was finally free. Free from what? Life. Frisk, no, Chara had killed him. Its the normal "human falls down a hole a gets possesed by a vengeful demon" story. And they had killed everyone. Even him. He was dead. Or dying. He could faintly see the outline of papyrus in front of him. His brother spoke

"Sans, I... I was told you would be leaving. Leaving me. Even in death. You... you have somewhere to go. Somewhere where you can make a difference. So this is my finial goodbye. Sans... I'm sorry. For everything. Pestering you about the puzzles, always trying to get you to clean your room... It was tiring. But you put up with me for so long, taking care of me.. my death was not your fault. It was theirs" He said, looking back at frisk-chara-demon-thing.

"I'm... so sorry. And sans, someone told me. About the... What did he call them? Alternate universes? Yes. Alternate universes. Ones where we were friends with the human. Frisk was her name in the other timelines, correct?" He didn't wait for a response.

"I just want you to know... you were the best brother ever, sans." And as he faded away, sans realized why he had felt that something was wrong. For the first time ever... Papyrus wasn't yelling.

At first when sans woke up, he didn't remember anything. Nothing. His mind was an empty void, filled with whispers of past memorys, taken, and erased. But then it flooded back. The kid, the underground, being a skeleton... Papyrus. A small tear formed in his eye, and rolled down his cheek... wait, cheek! He doesn't have cheeks. He looked at his arms, legs, hands, feet... all covered in skin and muscle. He got up off the ground where he lay, surrounded by luscious green trees. Trees? The underground had trees, but not like this! Was he... on the surface? Looking around him answered his question. Mostly the sky part though. That was the real obvious one. He started walking, enjoying the feeling of actual shoes on his feet. After about a mile, he found a clear pool, the water as smooth as glass. He looked down to the water, and stared at his reflexion. He was a teenager, with pale white skin, blue eyes, and long white hair. He was wearing his signature hoodie and shorts. But before he could leave, he heard a growl behind him. He turned around, and saw a huge black monster, with white bone armour, and glowing red eyes. It had big claws, and looked like a bear. How does he know what a bear is? He's a scientist that can see glimpses of other universes. Of course he knows what a bear is! He didn't want to kill this bear thing, but it seemed to want to kill him. A lot. He tried to scan the creatures soul, but he couldn't find one. The power was working, but no soul was coming up. Then a shocking realization crashed down on him. This creature, whatever it was... didn't have a soul. But it was still alive. And charging at him. He activated his power, and teleported away. He summoned some bones, and threw them at the beast. A few missed, but three stabbed in to the creatures side. It staggered to the side, and sans threw another bone at its head. It bounced of the bony armour, and did nothing.

"Looks like your gonna have a bad time." Sans muttered under his breath.

He summoned ten more bones, and launched them at the beast. They penetrated its back, stomach, and sides. It staggered to the ground, and faded away. Sans walked away, more alert now that he knew that their were those... things. He walked for what seemed like hours, before coming to the end of the forest. He could see a city in the distance, and decided to go to it. He put his hands in his pockets, his usual stance. But in his pocket, he felt something. There was a leather pouch, filled with coins. Next to it was a note. It read:

Hello, sans. Welcome to the world of remnant. In this world, there are creatures called Grimm. And, they are called monsters. But, they have no soul...

The note went on to explain everything about this world. (I'm not gonna write an entire chapter worth of remnant info.)

"Huh." Sans said out loud.

He then set off to the city in the distance. Once he got there, it was night. He went to something called a dust shop. Inside, there was the store clerk, and one kid wearing red, and reading a weapon magazine. He went to the actual dust part of the dust shop. Their was dust of every color. As he was looking, a bunch of men barged in.

"Do you know how hard it is to find a dust shop open this late?" The first one said.

He then commanded the others to get the dust they came over to sans.

"Move it, kid." One of them said.

Sans simply raised an eyebrow, and looked at them. He turned back to what he was doing.

"Hey, punk, get out of the way, or your gonna regret it!" Another one said.

Sans just ignored them.

"Alright, thats it, take this!" The second one yelled, swinging a fist at sans. But then, their vision flashed black... sans wasn't there. The men looked around wildly.

"Whats taking so long!" the first one yelled from the counter.

"The- their was this kid, but he disappeared!" One yelled.

"Ugh, your useless!" The first one yelled from the counter, walking over to the others. He looked at them skeptically.

"A disappearing boy." He said, disbelievingly.

"Yup, that's me!" Sans yelled from his positing on top of one of the shelves.

"What!" The first one yelled, turning to sans. He stared at him, dumbfounded.

"Now... leave." Sans said, ending with his scary voice. They all looked at him in shock, before a smile formed on the first ones lips.

"You really think you can beat me? Come and try." The first one said. He then shot a bullet out of the end of his cane, and smoke erupted everywhere. Sans could just barely hear someone saying

"Get the dust and go".

Sans already hated these guys. He Shut his eyes and teleported outside. Suddenly, one of the men crashed through a window, followed by the red girl. Oh, yeah, and she was carrying a giant scythe. Important detail. She jumped back in to the building, now smoke free. Sans followed her, choosing to teleport instead of walking. As he got in, he could see the men fleeing up a fire escape. The red girl saw to, and they both followed the man. Sans teleported to the top of the ladder, while red girl climbed. At the top, they saw the first man trying to get in an aircraft. He turned around, and threw a red dust crystal at their feet. But as he went to shoot it, someone came rushing in, and put up a purple barrier around them. The woman that saved them started shooting purple bolts of... something at the ship. The man ran back inside, and out came a woman who's face was covered in shadow, came out. She summoned some fire, and shot it at the other woman who saved them. The woman who saved them just shot more purple at the fire, breaking it in to little pieces. But the fire reformed, and the one who saved them just barely jumped out of the way. Red girl decided to help, and her scythe turned into a sniper rifle; she then shot lots of bullets at the ship and fire girl, but fire girl just destroyed them. Sans decided to help to, and threw some bones at the ship. Fire girl stopped them all, even though they were going fast. Fire girl seemed to hear something, and ran back in to the ship, the door closing behind her. Then the ship flew away. The woman turned to us.

"So. It looks like we have a lot to talk about."

Hi! In the future it will be more comedy. This is not a feels story! Just so you know.
