UNDERTALE: LAST CORRIDOR

Your footsteps echoed through the eerily silent Space Corridor, the bright glow of the stars above you shining down on you from the place where the ceiling is missing, revealing the stars above.

The dark blue pillars that were supposed to support the ceiling slightly floated above ground, as a bright blue mist seemed to seemingly come out of nowhere above the air.

You had killed every monster in this AU, and now...it was time for Outertale Sans to go. You spotted Outertale Sans at the end of the corridor, floating slightly above the ground with his hands in his pockets, that usual grin on his face, even if you knew he was anything but happy at what you had done to his people.

"so...you finally made it, eh?"

Outertale Sans's laidback voice echoed through the silent corridor, as he stopped floating, his feet landing back down onto the ground but his hands remained in his pockets.

"well...i must say i didn't expect much else from ya. the second you left the ruins, and i saw all that dust on you...i already knew you were just a dirty murderer."

Outertale Sans said, his tone growing more serious as his oval-shaped pupils dissapeared, leaving just empty, dark blue sockets.

"...let's just get to the point."

Outertale Sans, his pupils not yet returning as he stared at you, awaiting your first attack.

It was now, or never. Either you kill him, get to king Asgore and kill him too and end this world as a whole, or he successfully makes you stop coming back from the dead and saves the entire world.

...You have only one objective. Drain his stamina until he falls asleep or just can't use anymore attacks or dodge any attacks from you, and finish him off with a single attack.

Good luck =)
