FNAF and Undertale Crossover: Nightmares Within

Chapter 5: A TuToriel on possesion

You awoke to Frisk shaking you awake.

"Michael! Finally you wake up, I was getting worried you wouldn't wake up." Frisk said hugging you causing you to blush a little.

"Ok? How long was I-I asleep?" You asked nervously, hoping you weren't asleep for too long...

"2 Hours!" Frisk said surprising you.

"Wait what!? I was asleep for that long!? Wow, the Void really passes time does it?" I said, but realized I talked about the Void. How did I know that?

"Wait, you were in the Void!? Was Chara there? Was Gaster there? Was anyone else there?" Frisk started to ask lots of questions

"Wait, calm down! I-I was in the Void, but... I don't know about the V-Void. I don't know how I knew that. And yes, C-Chara was there, but Gaster wasn't. She s-said he had some things t-to do. And... Nightmare was there! And Chara is fighting him!" I explained to Frisk.

"Oh, ok. Well, we have to go. And explore the rest of the Underground!" You said in a happy voice. The Underground?

"O-Ok, but what about T-Toriel?" I said.

"Oh, we'll just ask her."

...

"I know what you're after, Toriel."

"What do you mean?" Toriel asked with fear.

"You want to keep them here. Raise them as your own, protect them from Asgore."

"What? I-I mean, I want to keep them but..."

"But you'll do whatever it takes to keep them here. Even if it means to kill them!"

Nightmare stays invisible as he laughed. Darkness filling the room.

"Now. Do you wish to suffer with Michael and Frisk? Or join me in catching them?"

Nightmare revealed himself causing Toriel to gasp. He held out a hand to her for a handshake.

"Now, which one will it be? With them? Or with me."

Toriel took some time to think. She took Nightmares hand. She felt an urge to kill. She had an urge to kill Michael and Frisk. She had her mind taken from her, and now she'll be this way until her death. But, one hit of any kind... Any damage of any number...

Will kill her!

...

You and Frisk were trying to find Toriel, but she was nowhere to be found. You checked the living room, the kitchen, her room, everyroom! But she was nowhere to be found, except the basement maybe?

"Maybe she's not here? How about we just leave." I said hoping she would agree, she did.

...

We stood there, in front of Toriel. She seems to be acting rather... strange. She then turned around. She had a stern look on her face, and her eyes... were red!

"Hello my Children. After keeping you here, I've decided... no children shall live here, ever. So instead..."

The area turns black as her hands light up with red fireballs.

"I'll kill you both instead!"

*Toriel blocks the way.

Music comes from... somewhere as Toriel starts throwing red fireballs. They're HUGE making it hard to dodge them.

Frisk decides to use spare, but Toriel didn't accept it. She just threw more fireballs at us.

"DIE!" She yelled throwing dozens of fireballs at us both. It was a storm of fireballs as the basement lit up. It was a living inferno down here as the flames burned everything it touched while Toriel was laughing like a maniac.

"Toriel! Wait! You're gonna kill yourself!" Frisk shouted but Toriel didn't listen.

This wasn't normal fire. It was a different type of fire. A fire that burned through anything and everything! Even metals!

We ran past her and through the doors as she tried to burn us.

"Hey! Where are you two going? The fun just started! Ahahahahahahahaha!" Toriel laughed as the fire attacked her, burning clothes and through her skin.

Her ear piercing screams rang out through the Ruins as her house and only her house burned down while everything remained.

We kept on running until we got to Snowdin. Flowey was no where to be seen.
