Under Infusion Tale- (An Undertale Fanfiction Novel)

Chapter 21: Fighting To The End

Red. Purple. Orange. Yellow. Green. Sans looked at all the colors in Frisk's hair. Her skin was different shades, glowing from one to the other. So overloaded with power, power shoved into her, against her will. Even blue was in it, but it wasn't his blue power. His 1% was gone like the wind. They had enough power jammed into her to completely erase his. The only faint detection there was ever his power with her, was the magic forever sealed in her marrow. Even the tips of her hair were now missing it's natural blue.

Sans noticed all the humans standing around, but he could sense clearly, they weren't people. They were monsters, and not from the Underground.

He didn't care about who they were, how they got there, or if they were responsible for the barrier or not! All he knew is that each and every one of them that hurt her, and that tore him away from him, was about to die. They just weren't aware of it yet.

"Death. Sentence. Written." Undyne was beside him with her spear. With Sans ring still connected to Frisk, they had managed to teleport out of the barrier. "They stole your wife and took what was left of yours inside of her."

Sans just stared at her. Bone marrow wasn't enough to be married. He had already reduced her down to 1% for evolution. No one toppled marriage. It took a lot of force, and a lot of monsters to do that. But by letting her have only 1% he just guaranteed it.

Technically, by modern day standards and contracts, he was married, and her only husband. But by monster tradition? By the classic ways of an acceptable marriage? Letting Asriel keep his energy was one thing, it was all about the wife's energy, and what was inside of her.

And. Breaking that. From him. Stealing that from her, and flooding her with their own powers?

"Who's the little guy and the fish?" The one in charge said. He sent a ball of energy Sans' way. Sans not only dodged it, but used the opportunity to pick up Frisk.

"Nimble little thing, aren't you?"

Frisk finally felt something in her that wasn't pain. She tried to concentrate on it, like it was hope. Faith. Like it could save her. Just hold onto it. Whatever that is, hold onto it. She tried to bend her fingers to cling onto her hope, but her body was swayed away so fast. Yet, her hope was still there. All she could hear was static and screaming in her ears from her soul, but she knew with hope, if she could just concentrate, she could make it through it.

Then, she heard different screams. Screams that didn't sound human, and the feeling of the warm hope increased into something she recognized. Sans. Impossible. They raised the barrier, it couldn't be. But, she knew that feeling. That warm, safe feeling. She could now feel her sense of touch coming back. Bone, she felt Sans' strong bone. "I'm still me," she breathed as she felt his bone. Her fingers could curl now. "I'm still me. I'm still me."

"Here comes another barrage, Sans, hold onto the Punk tighter!"

Sans dodged another attack. He calculated the degrees he would need to set up his ultimate weapons again, but first he sent out a fleet of spinning bones back out, and dodged a right attack while Undyne sent out her own strong spear attack, hitting several monsters, several times at once. If they had been real human bodies, that battle would have been over.

He couldn't just teleport away with Undyne. They held power in Frisk's soul, and it was too strong for him to vanquish. He had to vanquish the sources to free her. All eight of her new husbands.

With Undyne's assist, he would do just that, or die trying. Over, over, over, over, over, there! He sent a tunnel of bones swirling through them all, Undyne combined her spear attack, hitting the targets several times over, and then Sans set out five of his ultimate weapons.
