   Summary

   Massacre sat up and rubbed at his sockets as he looked around, confused. The last thing he remembered was the fight he had been in before- he had been pushed int one of those inky portals and now he was... where was he? He stood and scratched at his neck a little as he felt the liquid hate begin to fill the back of his throat. He needed to stay calm otherwise it would get worse, but he couldn't help how he was feeling.

   Taking a deep breath, Massacre took stock of his situation, finding that he was in the garden of a castle- was he home? No...it looked way different to what home was. Before he knew it the liquid hate started spilling out of his mouth and he collapsed on the ground, coughing out what he could.

   Or: A fell version of Killer from another multiverse ends up in the regular Undertale multiverse and Nightmare and the gang take him in.
