Last Corridor

- Frisk walks down the last corridor and meets Sans.

Sans: Well hello!

Sans: I have a question for you how to tell you?

Sans: Do you even think that even the worst person can change?

Sans: Can they become someone better if they try?

- Frisk takes one step forward.

Sans: So, here's a better question.

Sans: Do you want killer time?

Sans: 'Cause if you step forward.

Sans: You definitely won't like what happens next.

- Frisk takes one step forward.

Sans: Sorry lady, that's why I never keep my promise!

Sans: You know, I understand that you were trying to protect yourself, but killing those who did not even try to attack you was too cruel, you just have to burn in hell.

- Frisk makes a dash, but Sans uses a portal in which Frisk moves to another place Sans uses Gaster's blasters and sharp bones, aiming at Frisk, he shoots at Frisk, Frisk dodges all attacks.

Sans: It's good for the first time!

- Sans uses the portal, Frisk understands and stops, but Sans's fist went through the portal because it was a simple portal, this throws Frisk far away.

Sans: Now you know my trump card between a simple portal and a portal that violates the laws of physics with its movement.

- Sans is preparing the dark magic of chaos, the shadows began to pursue Frisk, sharp shadow spikes came out of them, Frisk began to run away, Sans did not allow this by firing from gaster blasters, Frisk used spells to turn off the magic of the gaster blaster, and in response Frisk shoots at Sans from spells that created a big explosion, Sans moves with the help of shadows and moves away from this attack.

Sans: Timeline has the law of inverse cubes.

Sans: Some atoms become unstable, become radioactive, while others become stable.

- With the help of the soul power, Frisk regenerates, but Sans's karma is very strong, it was called True Karma, the poison effect that ignores absolutely all immortality.

- Sans uses Chaos of Light, he uses a flash to blind Frisk and throws light attacks that also blind her, however Frisk is not lost with spells, she creates a protective barrier when she was able to see that she teleported to Sans with spells, she swung Sans expected this and dodged, but Frisk was able to scratch, he slowly regenerated, he realized that the sword was not simple, and that if he was cut in two, he would die.

Sans: Type 1, type 2A, type 2B, SO(32), E8 × E8 and Supergravity, It's all in the alternate universe.

- Sans waved his hand, in hand a sphere that created an explosion that pushed Frisk away, then he prepares the bones by throwing them, they also explode.

- Frisk dodges and realizing that he will not dodge all attacks, he decides to use a powerful slash that destroyed all attacks.

Sans: The world or, more simply, the parallel universe has strings that can predict the motion of the space-time string.

- Sans reverses gravity, directing gravity upward while the bones gain kinetic energy to make the attack faster and stronger, and starts firing them at Frisk.

- Frisk creates a barrier with spells, Sans's attacks cannot destroy the barrier.

Sans: Chaosworld, or rather the multiverse, which we call chaosverse, chaosworld contains all conceivable ideas, theorems of cosmology and mathematics, including such things as inaccessible infinities, Platonic forms and CU, it contains everything.

- The strings patience fall out of Sans' hands like a 404 error. Frisk is immune to manipulation. Sans can just grab her for a while or slow down her speed. Sans also prepares ice bones and ice gaster blasters, he starts firing them at Frisk.

- Frisk dodged the attacks and cut all the string, she remembered all the attacks, Frisk was able to approach Sans and hit, but Sans dodged Frisk's attacks again, then she attacks Sans again, but now Sans kicks in the stomach and then makes an ax kick on the head, leading the upper body. Sans knows all the techniques of fighting techniques, knows how to work on his body and move correctly.

Sans: Our strength is enough to shake the world!

- Sans uses fire bones and gaster blasters and fires at Frisk, then prepares gaster blasters that fire explosive beams.

- Frisk dodges, but now she uses 5% strength, she can use her sword to do a slash attack, one attack is directed towards Sans, Sans used the green platform as a shield.

Sans: Alternate universes jump left and right, stopping and continuing. And then it all ends abruptly.

- Sans prepares light gaster blasters and dark gaster blasters, light gaster blasters blinded the enemy when firing, so when they started shooting at Frisk, she blinded Frisk, but Frisk received resistance from this and the blindness did not affect her so much, she dodged from all attacks, but received little damage.

Sans: Yes, you know that, I didn't even have to say it, but the difference is that the ability works in alternate universes, in timelines, it does not affect.

- Sans creates clones, some of them are illusions, they create a sphere from the ball due to different elements of nature and run to Frisk. Frisk fights off other attacks, one clone ran up to Frisk but it was an illusion and another clone was able to deal damage, this time she was focused and was able to destroy the clones, well, she was seriously injured.

Sans: You know, maybe you will give up, let the world start over, but with a happy ending, we can forget everything, just give up and start the world over.

- Frisk continued to fight, but Sans dodged and teleported away from Frisk using the portal.

Sans: You decided to continue the fight, you yourself know what will happen next.

- Sans is preparing lines of determination, they are able to remove from the code, if the enemy had immunity, she could erase everything that allowed her to ignore durability, but Frisk had immunity to deleting the code and erasing, so the lines could only be cut.

- Frisk cut a few strings with his sword, but some of the strings get hit. Frisk uses spells, she teleports to Sans and cuts all the strings, then attacks Sans, Sans reacted and pulled out the ninjato sword, her name is "last light" Sans blocks with the sword and pushes Frisk further.

Sans: Not only you have a weapon!

- Sans readies the gaster blaster and fires at Frisk, but now she releases a sphere that explodes differently, some of them shoot in a volley like bullets.

- Frisk dodges without problems, she approaches Sans again, Sans repels the attack with his sword, but Frisk hits Sans 2 times and he defends himself with his sword, then beat the sword to the other side, and used dark magic, Sans's sword went through Frisk's sword, Frisk reacted and dodged backwards.

Sans: Did you know that the last corridor is in present time? so you can determine the speed, we are much faster than space and time.

- Sans started using lightning magic, he used lightning bones and lightning gaster blasters. Frisk repelled attacks, they were not dangerous, but now Sans uses sonic abilities, bones emit sound waves when hit, and gasterblasters stun Frisk when they hit, Frisk was able to survive all the attacks.

Sans: I don't know about you, but I have limitless stamina, I will never get tired!

- Sans prepares bone bombs, they do not explode, but a lot of bones fly out of them. Frisk uses 30% of his strength and makes a circular barrier so that no bones can hit her.

Sans: I have a form, it is called the butterfly form, believe me, in this form I am able to bring down all the worlds.

- Sans prepares gaster blasters, they begin to gain more energy and self-destruct, Frisk runs away from these gaster blasters, but she took one and threw it at Sans with great force, Sans escaped from the explosion using the portal.

Sans: Butterfly shape, i transcend all concepts of time-space, including transfinite numbers.

Sans' eyes started flashing orange and blue, the orange and blue bones turned purple, this did not let Frisk know about the attack, they closed the wall and started attacking Frisk, Frisk memorized all 30 of Sans's eye blinks and did not take any damage.

Sans: In the form of a butterfly, I break all the speed formulas.

- Sans changes the appearance of Frisk, now she sees everything the other way around, but she is used to this Sans attack with a gaster blaster and bones, she dodged them all.

Sans: If I consume the fountain and 10 souls, I can destroy the Chaos World.

- Sans prepares poison bones and gaster blasters and then uses strings to throw blasters that try to bite Frisk, Frisk dodged but took damage, and the gaster blasters managed to bite through, she destroyed them.

Sans: Your aura is filled with a demon, don't tell me how I know that. I just can see aura and energy.

- Sans prepares the bones, which come back like a boomerang. Frisk was aware of these attacks and they were easy to dodge.

Sans: Our fight can't go on forever!

- Sans throws Frisk with telekinesis, then shoots Frisk with a Dream Sans-like bow, Frisk destroys him with a slash attack, then Sans prepares a beam from his hand, which took away a lot of Frisk's health.

Sans: Get ready because I will use 5% of that power. I can foresee all your moves and you want to see a bad ending? Although you probably won't be interested!

- Sans throws the dice, he foresaw all the movements of Frisk, but Frisk has a very strong reaction, she barely dodged, got big injuries!

Sans: It's time to end this fight, otherwise your death won't bring the others back.

- Sans opens a portal and leaves this room. Tired Frisk moves on.
