The lore: Its a Dusttale/Dustdust timeline and Sans killed everyone but upon getting to last corridor, he noticed that the human never came and they never did for a 100 years... Until another human fell down to the underground and well.. The undergroud is empty and only Sans, Napstablook, and the Amalgamates are left. Sans encounters you at snowdin and at the last corridor gives you a choice to either let sans kill you or stay here. Sans has 25 LOVE The reason why Papyrus looks like that is becuase hes a hallucination but Sans forgot how Papyrus looked like and thats the reason why Papyrus looks like that here are the endings: Pacifist: you spare sans at snowdin and decides to stay in the undergroud with no way out waiting for another human. Pacifist(alt): sans kills you (gameover) True Pacifist: sans kills you and gets out of the barrier Genocide(spare during fight): you fight sans at snowdin and during the fight at the last corridor you spare sans and sans kills you and gets out of the underground and destroys Humanity Genocide: you kills sans at last corridor and resets the timeline and brings everyone back. Btw Mad MEGALOVANIA plays only at Genocide Last corridor. The AU is called DustDust: faded memory.
To him, they are monsters. To us, they are just products of code. I will be real here, most of us does the genocide because we know its existence and consequences yet we done it so we can discover another part of their code.
Well he is trapped in the underground for years so maybe that's why he missed everyone. Or *regret* it. I'm still confused why this half meter sized skeleton managed to live for decades 💀
Sans but papyrus is dead, so he’s sad and he kills all of the monsters for EXP, and also it’s happening in outer space, and everyone is edgy, and the characters are swapped, and also he can destroy or create anything he wants because error and ink
