(AN: Heya guys; first time writing an Undertale fic a.k.a first time something not Homestuck. I really wanted to make something like this, even if it's a little OOC, because I absolutely love the ending. To my long time followers, I'm working on my other stories as we speak. I've hit some writer's block, and I figured if I worked on something else, I'd think a bit clearer. Anyhow, I'll stop talking and let the story roll! -John).

Chara walked down the hallway, smiling as the light cast their shadow. This was the funnest part: the beginning.
Grinning as wide as they could, they greeted the skeleton before he could even appear. "Greetings Sans."

Sans stepped out from behind a pillar, his smile matching Chara's, his eyes just as empty. "Heya." He paused, staring coldly at Chara. He knew what was going on. "That expression you'r-"

Chara interrupted him, of course. "Come now Sans, are you truly going to repeat yourself this much?" Tilting their head, they went on to say, "Wouldn't it be much more fun to say something new to see what I'll say in response?"

Sans chuckled. "Heh, screw you kid." His stare remained unbroken.

They kept smiling. "How long have we been playing together Sans? Weeks?" They took a step closer, trying to intimidate the skeleton. "Months?" His smile somehow grew more menacing as he walked closer still. "Years?" His red eyes gleaming with delight as he saw a bead of sweat go down Sans' head.

"What can I say? I don't have anywhere better to be." He shifted his gaze directly into Chara's eyes. "You must not either." His sockets devoid of any light.

Chara began to tut. "Tsk tsk tsk. I may have killed you countless of times, but you see, I have not yet won with you." They took out their knife, turning it in the light. "I want you to lose."

Sans expression didn't change, but Chara knew him well enough to know he was confused. "I want you to sit there and let me kill you. While I find the fact that you believe you can stop me to be utterly entertaining," They paused, their focus drawn to the knife. "I have a persistent feeling that you will stop me in every timeline."

"If I can make one of you abandon that utterly pointless hope, that is when I will let you die."

Sans looked at his killer before responding, "Wow... You really are a freak, aren't you?"

Chara's smile faltered a bit as they sighed. "While killing you is fun, I've heard everything you have to say. Every move you can do. Perhaps I'm not making this very clear." Chara's eyes erupted into their cherry red glow. "You were never in control in the first place. Do you think you can stop me?"

"I will let you die, Sans. Then you can return back to some timeline until, well, I do not want it to exist anymore."
Chara moved right in front of Sans, a slight nervous expression broke through his emotionless face. "Do you not miss your brother? Do you not miss the voice behind the door?" Chara raised their knife. "I can give them back to you, I promise." They grinned smugly as the knife reached it's apex height.

Sans stood there. Everything they said was right. He did miss Papyrus and the old lady. Maybe this what the anomaly wanted. Maybe it'd stop if he just gave up.

The knife struck it's target.

"Sans! Wake up you LazyBones!" He heard.

Yawning, he replied, "Sorry Bro, had to take a nap before I went back to sleep."

Opening his eyes, he saw his lil' bro, with that slash through his body. "Sans, now is not the time for japes! You cannot give up so easily!"

Sans looked around. This had to be a dream. It was their living room, just like it was suppose to be. Except Papyrus still looked pretty dead.

"Pap, what's going on?" Sans asked his brother.

Papyrus put his hands on his hips, exclaiming, "You know what is up, brother! You gave up without even trying."

Sans shook his head. "I tried for everyone Bro."

Papyrus took one of his hands and placed it on Sans. "Sans, you know that I am very great, correct?" He went on before Sans could answer. "And if I am very great, that must mean you have greatness within you too! Granted, not as much, but if you dig a little deeper and try a little harder, I know you can do it!"

Sans looked at his deceased brother. "I just missed how everything was Pap."

Papyrus grinned. "If you ever miss me, just remember that I'm always right here." He touched Sans' chest.

"I uhh, don't think you can fit in there bro."

Papyrus face contorted at his brother's joke. "Sans! You know what I mean! I'm in your metaphorical heart!"

Sans chuckled. "Heh, you still laughed."

"That is not the point Sans!" Papyrus exclaimed.

Sans pulled his brother in for a hug. "I missed you big guy."

Hugging his brother, Papyrus said, "Sans... You can do it! I believe in you!" Taking a step back, he told him, "And if I believe in you, that means you cannot give up!"

Sans nodded, everything around him beginning to fade away. "Don't worry Pap, I'll make you proud."

Before darkness overtook Sans' vision, he heard, "You already have Sans!"

Chara made their way to the end of the hallway when they felt themselves become weaker. It was barely noticeable, but it was there all the same. Looking inside themselves, they saw they were one exp point less than a second ago.

Turning around, they saw Sans' dust shaping back into him. Enraged, Chara ran back, knife in hand, ready to strike.
Slashing, the knife had hit the skeleton again, as hard as Chara could swing. They broke out into maniacal laughter. "I already beat you! This time I will save over your death! You will never come back!"

-Hit-!
CRITICAL STRIKE
9999999 DAMAGE

Chara saw that the knife had indeed hit Sans.

He was holding it.

*Sans remembers what he is fighting for.

His smile covered his entire face, leaving Chara confused and irritated.

"Why won't you die?!" Chara tried to pull back the knife, back Sans refused.

"Heya kid." His voice echoing throughout the hallway.

Sans' body had completely transformed. His blue left eye had been joined with an orange right one. The fluffy slippers were gone, replaced with boots much like Papyrus'. Even his robe took on Papyrus' color scheme. His eye sockets were ever so slitted downwards, giving him a menacing look.

"I might be a pushover, but if you thought I'd just let you win,"

Chara looked behind him and saw blue, orange, and white gasterblasters descend from the ceiling. All of them over triple their original size.

"Then you're in for a worse time than you thought." Sans broke Chara's knife as he crushed it with his hand.

Chara had never really felt emotions, nor did they now. But, there was one thing in the back of their mind, one primal instinct not even they could escape.

Fear.

Being lifted up, Sans threw them straight into a pillar.

"Come on kid, loosen up."

Sans had combined both orange and blue bones to his attacked, repeatably hitting Chara, only knowing the pattern from before.

"After all, the birds are singing, the flowers are blooming,"

Sans had taken away the platforms, forcing Chara to crawl through the bone pit.

"And on days like this, kids like you,"

Chara was able to punch Sans; he didn't move.
He didn't have to.

Sans picked Chara up, bringing them as close as possible to him face. Chara couldn't feel their arms and legs; not even their eyes were allow free to move. Sans positioned Chara inches from his face.

"Should be burning in hell."

Sans throw Chara back, unleashing an unavoidable blast from the gasterblasters.

Chara, you cannot give up!
Stay determined!

Chara walked down the hallway, frowning as they slunk with the shadows. At least they knew what not to say this time wh-
Sans hadn't changed back to his normal form.

Chara's eyes grew; they searched their inventory to find that the knife was still gone.

Sans saw the kid and smiled. "Heya kid." Studying them, he said, "Hmm... That expression you're wearing..."

Summoning the gasterblasters and bones again, he went on to say, "That's the expression of someone who knows they went too far and can't take it back."

He grinned as Chara realized that there was no going back.

"Let's just get to the point."
