Heya. I know these summaries can get tedious so I'll get right to the point. This story follows Sans in his arrival into Academy City as a new student. All reasoning as to why will be explained later. His appearance… you'll see. As a fan of generic Sans not much will change on him. As for his route? He comes from… Genocide. A route where Chara, you, give up fighting Sans and he is left alone after you admit defeat. This story will NOT feature Chara nor Frisk as a main character. Nor Asgore/Flowey.

Railgun wise? To avoid possible spoilers, I'll avoid alluding to anything about Railgun in future episodes and start off before the Level Upper was introduced to the public. Note that things may not happen in the same order as they do in the show.

Thank you for reading and I hope you enjoy. Without further ado, I give you… Lost Element.

Chapter 1: Ariel Gaster

A cold breeze blew as yet another bone chilling snap filled the air. The bone projectile went directly through the child's insides and came out on the opposite sides. The smell of blood filled the air, a fitting setting for the blood curling screech that came out of the kid. However, Sans took no pleasure in this. He only readied himself for the world to go white and reset again.

And then it did.

As the white died down and the room came into focus again, all Sans could see was the same hallway he'd come to know as his own personal hell. Vibrant colors of orange and yellow soon to be covered only by the dust of battle and LOVE it had come to be. Looking his opponent in the eyes he could muster a chuckle at the desperation and rage he saw, "Heya. That face you're wearing… I can't even tell how many times I've killed you now. Twenty? Thirty? Who knows. All I know is tha-"

Chara slashed out at the skeleton in an attempt to achieve a surprise, only for the skeleton to teleport behind the demon and deliver a massive blow with a rather large Gaster Blaster. "...Is that I'm getting real tired." Frisk leapt back to their feet Hit Points restored and a demonic look to their face.

Sans sighed. "Have it your way kid…." He flicked up a field of bones that ripped apart the floor in a zigzag race to be the first to hit Chara. They jumped out of the way, using inhuman like strength to hold onto a nearby pillar and dodge his attacks. "Our reports showed a massive anomaly in the time space continuum. Timelines jumping left and right, stopping and starting…"

Several Gaster Blasters materialized from the air around the Demon with the desire to kill in an instant. Frisk barely had time to dodge before the skull's wicked jaw dislocated from the sides and the eyes began to flicker, letting out a deadly beam of light that vaporized the spot they were hanging and the pillars that stood behind it. "Until suddenly, everything ends."

Chara hit the floor on all fours, dust covered dagger in hand and breathing heavily. "Heh heh heh… that's your fault isn't it?" Charas eyes opened wide as six bones, as tall as the room itself, began making a path of carnage towards them. Weaving left and right they tried to dodge the bones, but every time one went by it just turned around and came right back in for another shot.

The skeleton's eye began to glow with a blue fury reserved for only the worst scum of the Underground as he raised his hand, molded like a finger gun, at Chara. "You can't understand how this feels!" he yelled, an enormous Gaster Blaster firing immediately at the child, striking them directly in the chest and sending them flying across the room, blood spraying everywhere. Charred bits of cloth hit the floor as Chara clutched the hole in their chest, the wound already healing but at the cost of Hit Points.

"Knowing that one day… without warning.." He readied another attack, but found that Chara had disappeared. There wasn't any smoke in the room nor was there any LOVE signatures in the room. "It's all going to be reset..?"

Sans looked around the destroyed judgement hall but found nothing. No major outcrops to hide behind. No cheap tactics to surprise him with. After a few moments of searching for where his opponent could have gone, he gave up. "huh. where'd the pipsqueak go?" he asked himself as made his way to Asgore's chamber, the dust finally setting to rest behind him in that forsaken hallway. It didn't make much sense to Sans that Frisk would leave the battle, no he would have sensed it and gave chase. Something was wrong… no, not wrong, Different. He hadn't seen this in one of his dreams before. This was new.

Pushing aside the grand door he entered the Royal Chamber, flowers lie happily in the ground awaiting their daily water. Sadly however, it seemed Asgore was nowhere to be found. So instead Sans made his way to the back room. Perhaps Asgore was waiting at the barrier preparing to absorb the souls as ordered by Alphys. He began walking through the grand golden arches into the darkness of the cave. It made him stop a moment to adjust his eyes, but overall there was still enough light from the surface to see.

Near the end of the walkway was a single archway, but the entrance was blocked off by what seemed to be a cave in. Shrugging Sans just teleported behind the rocks. He had been there before after all, he knew the coordinates.

On the other side lie the whiteness of the barrier. "Still up I see. Huh, even with everyone dead it still stands strong, huh." He wasn't in the mood for any humor, but still felt it enough to talk to himself. "Wonder how long it'll take to stretch the old funny bone?"

"You've come to the wrong place."

Sans sat on the bus fingering the small pass in his hand. Hand. It had come to be a new feeling to him after the incident. Looking down at his left hand he traced the lines in his palm, eyeing the flesh with interest and curiosity. What had happened at the barrier that day was something he wouldn't forget. Something he'd have to remember for later. Something... Sans-sational.

"Your claims that you're actually a skeleton aren't strengthened by motions like staring at your hands, Arial." his guide told him, breaking him from his thoughts. Sans clenched his hand into a fist in response and smiled a big goofy grin at the name she called him. The name Arial was the name he had told them at first. Arial Gaster. Later when he had tried to clear up what his real name was, Sans, they only assigned it as his "codename". Annoying, but he was too lazy to try and fix it. It also seemed as if they refused to believe his story of being a skeleton and told him to stop pretending. He tried telling the truth...

Looking out of the bus window Sans watched trees and other scenery fly by. Shacks and roads seemed to be popular, but no other vehicles had crossed them since they left the capital. Instead people walked to their villages with pails of water and bags of rice. However, the bus brought no special attention it seemed. Closing his eyes as the sun met his gaze, he realized how fatigued he was and how much had actually happened since his last rest. His thoughts began to wander from place to place before finally neared a peaceful slumber.

"Not so fast there." His African American guide warned him before he could fall to rest, "You can sleep on the jet. We need to get your story straight first if you're going to make it through international customs." The black lady told him. He sighed, it wasn't the first time he had been told what to say in case he was questioned. Apparently waking up in a place known as Africa with American blood is cause enough for immediate relocation. Maybe a recap was in order.

After absorbing a Human Soul to escape the dead Underground, he had gained Humanity somehow. According to the locals the Now-Dead-Underground was located in a place called Africa, but the fact that he was white and had DNA lining up with a missing child from America seven years ago… well that was why he was on his way to the top research facility in the world.

"I am Ariel Gaster, an American student who lost all his memories and woke up in the diamond mines of Sierra Leone. All I want to do is get a proper education since that's all my parents left for me in their will. I am not to let them know about my 'dreams' of being a skeleton and wish to be treated normally, not as an Esper. I got it, I got it. I nose what I'm talking about." he chuckled. He had become notorious for puns like those. It was an amazing bonus being human that he had more body parts to make puns with. The woman only rolled her eyes in response, but seemed to agree he knew what to say.

The bus came to a stop and his guide stopped her questioning as well. "This is as far as the bus will take us. We will need you to telepo- I mean 'shortcut' us us to the airport." She told him, showing him a picture of an airport with the X and Y coordinates scripted below. Sans rolled his eyes but agreed as he opened a "Shortcut" to the location in the picture. One step closer to his destination. One step further from the Deadened Underground.

ATTENTION: Sans IS human now. The government knows ONLY about his ability to create "shortcuts" using x y coordinates. However, they know nothing of his: Short distance teleport, bone projectile, Gaster Blasters, gravity shift, Judgement eye, fragileness, combat manipulation, or Special Move: Megalovania. In the next chapter/ONE SHOT add on he will be in Academy City. This chapter was just set up sadly, but set up that needed to happen. You can expect a full out duel between our Electromaster and Skeleton in the future.

Catalog of Discovered Abilities:

Shortcut (Ability): Sans is able to teleport up to 500 Miles away if the known X and Y coordinates are present. However, without a picture of the location he cannot choose the altitude of his teleport. Without a picture he will ALWAYS land upon the highest land mass he can physically enter. (Ex. Rooftop) MUST be created in a shadow.
