GlitchDust's alternative

Split paths

"Hey Alph, what is it?"

Alphys then spoke out.

"Sans, it i-is r-ready. The p-portal to t-travel Alternate Universe, o-or just AU."

Sans nodded as he spoke out.

"Ya, I am coming. just need to grab some few stuffs, ok."

Alphys response with a "yes" as an agreement before Sans hang up his phone and puts it away. He turns as looks at Paps as he spoke out.

"Hey Paps, I'll be going now. Just gonna grad the device I been making for this moment, ok?"

Phantom-Paps nodded as he disappears. Sans then teleports to his house and enters his room. Once there, he goes towards his desk and grab his device. He then changes his old clothes to his new ones that Paps had given him on last Christmas. The jacket is the same as his old one, just darker blue compared to each other. His sweatshirt is dark gray than his original one. His shorts are longer than his original one. He puts them on as he spoke out to himself.

"Welp, these new clothes look great to me. Especially when Paps give me these on Christmas. Now, on to Alphys."

And with that, he is gone.

Alphys's house

Sans entered the front door and knock it. Papyrus and Undyne opened the door to see who it is. Once they saw Sans, they let him enter to the house to see the others. Asriel and Chara are in the sides of the room talking, Alphys is working the finishing touches, and Toriel and Asgore are their just bringing food for everyone. Sans is speaking to his brother Papyrus and talking about something. Paps then spoke out.

"SANS, ARE YOU SURE THIS IS OK FOR YOU? I MEAN, ABOUT THE PAST."

Sans nodded as he spoke out.

"I am ok, I just need to do this to protect you and everyone. Besides, by studying the AU, we can learn our world and maybe have a chance to bring back Frisk."

Paps nodded as he agrees on this. Truth be told, back years ago, A sans name Insanity came and tried to reck havoc to this AU. Luckily, Sans, Asriel, and Chara came along with the rest of the group who is in the room. due to because it is the middle of summer vacation where they came to Hawaii. This is well, brutal to say the least. During the fight, Sans's DT had grown to the point he manages to gain a new button. It is called the Reboot, and it appears in the middle of the fight. When Sans notice it, he was confused about it. After the battle, he examines it before taking a test-drive. When he presses it, suddenly all the internal system of his world reset. Causing everyone to remember not just Frisk, but also some previous timelines that came before. But not the ones that Sans committed his genocide. Sans was forced to explain what happened and how he stops the constant genocide that Frisk and Chara did. By either defeating Hate or convince Frisk to turn back, even it the way it did is a little extreme. He also explains why he look so different compared to his old self. Everyone's expression is mixed to say the least. At least eventually everyone, especially Undyne, that Sans was forced to do this and just doing it in response to this whole mess. Undyne even called Sans a strong individual by not just his strength, but his will and mind because he had power through it all even after going mad. He also explains Killer and Horror that their boss wants him and either takes him by force or by trying to destroy everything. He even mentions about Killer's past and how instead of Killing monsters just to stop it, he did it just to feel something new. Needless to say, Undyne and Chara were disgusted on that action. And combined with Insanity and what happened to him and the head of Papyrus, they concluded what the boss is not good in any means.

And right now, Gaster appears and looks at his two sons as he spoke out to them.

"Well, Sans is right in that we need to do this in order to have a better chance of fighting back these visitors after what they tried to do to Sans. I am not please that this happens to him even after it's been years. I'll likely have to analyze what is happening. Sans are you sure that you can do this alone. You could bring Asriel and Chara with you.
