So I just got this plot bubble and HAD to write it! So no, this story is finished, but I wanted to add this additional ending. (I think I've listened to one song too much... 0.0)

Chara reeled back, knife in hand. She kept swinging at the chubby skeleton, now aware of the presence of the two other souls. Like times previous, Sans kept dodging out of the way. He launched rows of razor sharp bones at her, which she dodged with ease.

"You can do it Sans," Papyrus exclaimed.

Sans paused for a moment. "seems like they're rooting for me."

Chara frowned. "You souls are irritating me!" She swung again. Yet again, Sans launched rows of bones at her.

Gaster looked to the ground. "It's almost time," he muttered.

"Time for what," Papyrus asked. Gaster pulled Papyrus into a hug. "Dad?"

"My son, oh my sweet son... Sans... you know what happens, right?"

Papyrus froze. "No. H-He's doing so well! He's not being lazy!"

Sans was still fighting. Beads of sweat formed on his forehead. "alright. survive THIS and i'll show you my special attack," he threatened.

Chara smirked and got in a defensive position.

Sans began his final assault. He sent rows of bones at the child, which she dodged with ease. He flung her into various walls, trying to kill her as he caused jagged bones to shoot towards her. She got a couple of scratches, but was otherwise fine.

"You can do it," Papyrus shouted. Gaster's grip tightened.

It was the final stretch. Sans began to summon gaster blasters, all directed at her. She ran around, always narrowly avoiding the blasts. In a final and desperate attempt, Sans threw her against the walls, hoping to kill her, but failing.

He panted. "alright... it's time... for my special attack," he wheezed.

"I already know what it is! You'll just sit there, and hope I give up," Chara sneered.

Sans' smile drooped. "i know. but... what else can i do?"

Papyrus' eyes widened. "No. Sans you have to fight back!"

"He won't. He's too tired to do that."

Papyrus' heart broke. He frowned at the child. He tried to materialize a bone, but failed.

"You can't do magic and have it work for this world."

Sans' eyes began to close. The beads of sweat began to disappear. Papyrus rushed to Sans' aid.

"the heart seems like it's worried for me." He closed his eye sockets. "heh. sorry heart, whether you're dad or someone else, it doesn't matter does it? I still couldn't beat that brat and now..."

"Sans," Papyrus cried.

"y'know, i never thought that sleeping would be how i died."

He began to snore.

Chara began to sneak up on Sans. Her footsteps were silenced by her careful footwork. She was close. She reeled her arm back and swung.

"No! I can't lose Sans," Papyrus exclaimed. He dove towards the knife. He felt a strange feeling welling up in him. Pain flared in his ribs. "Ack!" He looked down.

He was wearing a long red cape, much longer than his old one. He wore his familiar red boots, but the surface looked like a Gaster Blaster and bones lined the sides. Finally, his chestplate was pure white, except for a red heart in the middle.

"papyrus," Sans asked. His voice was a whimper. "what happened?"

Chara stumbled back. "You! Y-You're supposed be dead!" She held her knife with a death grip.

"Yes, I suppose I am, but I have someone I need to protect," Papyrus exclaimed.

She looked him over. "Papyrus, attack thirty, defense thirty. He reformed himself through some unknown method to protect his brother. Who could forget him?" Chara frowned. "No! You're not supposed to be here! You died in Snowdin," she snarled.

"Maybe I did, but Sans is my brother! I couldn't just stand by and watch you kill him!"

"How are you even here," Chara demanded.

Papyrus chuckled. "It's a little bit funny, actually. I thought you killed me, after I offered you a genuine Papyrus hug. Suddenly, I awoke in this strange room with no windows and doors. It was... a bit scary, even for someone as great as me." He rubbed the back of his neck. "But I found someone there. He had this vial in his hands." He held up his hands. "He held the vial kind of weirdly because he had these holes in the middle of his hands."

Sans' eyes widened. "wait! repeat that last part!"

"He had holes in his hands, Sans. Through Determination, I Papyrus, am back from that place, back from death too!" He glared at the child. "Chara, you thought that Sans was bad. You killed my friend in front of me. You nearly did the same with Sans." He summoned a bone. His eyes flared with orange flames. "You won't get mercy, Chara!"

Papyrus waved his hand. Chara's soul turned blue, causing gravity to shift for her. Several large Gaster Blasters appeared in the air above her. "Behold. My special attack!"

Chara frowned. "I can just move awa-," she started. She tried to move away, but Papyrus summoned lines of bones to block her path.

"Goodbye Chara!" The blasters fired. Chara fell to the ground. Her soul floated above her. Papyrus grabbed the soul before it split into pieces. He felt power surging through him. Papyrus turned to Sans. "I-I tried to help you and Undyne before but," Papyrus started. Sans suddenly hugged him.

"i love you. i didn't think that you would come back," he muttered.

Papyrus closed his eyes. "I love you too." He knew what he had to do. He began to walk to Asgore's throne room. "Come on Sans. We can finally get to the surface." He smiled.

Sans grinned. "let's go then."

The duo walked to the throne room.

Asgore walked towards them. "Sans, did you defeat the menace that this flower was talking about?"

Sans glared at the flower before sighing. "no. but my bro did. he took her soul and now we can finally be free."

"I see!" Asgore turned towards Papyrus. "I assume that you are Papyrus. It is nice to see that you are well!" Asgore frowned at the ground. "Tell me, how many casualties were there?"

"their LOVE was 19," Sans muttered.

"I see. So most of them perished. Papyrus, go ahead and do what you have to do."

Papyrus frowned. "No. There has to be a way that everyone can come too!" He felt a surge of power flow through him. Words appeared before him.

"Would you like to perform a True Reset?"

"Yes No"

Papyrus' hand reached towards the "Yes" button. "Goodbye everyone."

"papyrus wait!"

The world grew dark. The environment swirled around Sans and Papyrus.

"you reset the world."

Okay. I got this little plot bubble for this story. Another ending, if you will. Since Papyrus reset, Chara has no memories of what happened. Sans only will be able to recall bits and pieces.

Take this if you will. My original idea was closer to this than what happened in actuality.

The song I've played too much of is Battle Against a True Hero and Megalovania. :P

Hope you enjoyed this! Bye now, for real this time! :P
