IT'S ALL THE HUMANS FAULT...

Sans, going on a rampage through the entire Underground to get more LV and EXP than the human after remembering all the RESETS, he encountered his brother, Papyrus.

Since he didn't manage to kill Toriel in the Ruins because of the human getting to her first, he was forced to kill his brother as compensation.

But, in the middle of it all, his brother Papyrus fought back, critically injuring Sans, as Sans soon after turned to dust, and died.

Papyrus, now remembering all the RESETS, and getting the LV from Sans's previous genocide in the Ruins and some parts of Snowdin...he needed to finish Sans's goal...kill the human once and for all.

And now...currently...here you are...You, aka the human, standing infront of the extremely LV'd up Papyrus, or, as he is now called: Dustbelief Papyrus.

He stands infront of you, neon orange bone swords in both hands, as a slightly crazed grin is on his face.

"LET'S START THE SHOW, HUMAN..."

Dustbelief Papyrus said to you, the grin not fading from his face, as he prepared to fight you, and finish you off once and for all, since his brother Sans couldn't finish doing so...
