Before Frisk could hurt Monster Kid, her's and Chara's souls turned blue and were thrown away from Monster Kid. Frisk looked up and snarled at the sight of Sans standing infront of Monster Kid. Frisk laughed mockingly.
Frisk: Well, well, well. Look who finally showed up. Still afraid of Frisk?
Sans: I'm afraid that I have no fear. Expect of not being able to put you down Chara. Now get out of my future daughter in law, before I force you out.
Frisk stood up and cleaned the knife with a wipe of her sleeve. Sans' right eye turned blue and Megalovania started playing in the background.
Sans then used blue soul to slam Frisk into the ground. Frisk immediately jumped to avoid bones Sans summoned from the floor. He then blue souled her to the right and she was able to float through the gap in the wavy bones. She then jumped to avoid the Gaster Blasters Sans tried to use on her.
Sans: They say don't start with your strongest attack. Well I don't agree with that.
What followed was a battle, that had been fought many times over. Despite how well Monster Kid was doing against Frisk, Sans wasn't even able to land a hit. This was due to Chara using her memory to predict Sans attacks, since she had fought him in many genocide runs before this timeline. The only reason she struggled a bit with Monster Kid, was because she never fought him before. Because of this, not only could Sans not land a hit, but he was starting to get tired.
Sans: Okay, you clearly want to see my-
Frisk: Special attack? I've seen it hundreds of times and counting.
Sans: Well then, this turn will be the last one you survive, Chara.
Sans slammed Frisk to the ground with blue soul. Frisk then jumped to avoid the bones that spawned under her. Sans then used blue soul to throw her to the ceiling, but she jumped again to avoid the bones. He then slammed her to a cave wall and she jumped away from the bones. Sans slammed her to the ground again, but she jumped away from the bones. Sans then slammed her to the wall, and summoned bones from above and below her, but she was able to dodge them using a circle movement. He then slammed her into another wall and then sent her flying down a pathway, made out of bones. He then created a serpent type pattern made of bones, but Frisk was able to weave herself through it. He then summoned piles of three bones randomly in the ceiling or floor, but she was able to avoid them without much effort. He then summoned a pathway of bones that slowly closed on her, but she was able to slip through the crack. She landed on the end of the bone tunnel and jumped to avoid the bones that popped out of the end of the tunnel.
The cave then went dark and when the the lights turned back on Frisk did a little jump to avoid the bones beneath and above her. The lights vanished again and she found herself on the ceiling. She quickly jumped to the right to avoid the bones coming from the ceiling and left side. The lights vanished again and when they turned back on, Frisk was on the floor and she quickly jumped to the left to avoid the floor and right side bones. The lights turned off again and when they turned back on, Frisk found herself on the left wall, so she quickly jumped to avoid the bones coming from the left side. After she jumped, she quickly did run in a circle, as Sans summoned a wheel of Gaster Blasters around her a fired them. She was able to avoid the blasters and before Sans could slam her around, She threw her knife towards his chest. The knife then stabbed the ketchup bottle he hid under his hood.
Sans: Dang it, my ketchup.
Frisk: Finally, now die.
Frisk pulled the knife out of his ketchup. bottle, then swung her knife at Sans. Sans was too tired to try to dodge, so he waited for the knife to cut into him.
