(He has no AU like puppet sans, he's mainly just a joke because he's not an actual character, yet) you can be the other versions of sans like error, bill sans, error 404, ink, VHS, puppet, dust, and whoever. he is very dangerous though.

(you are normal or whoever you want to be) After you killed all of sansfield's friends, he is going to avenge them by killing you or shipping you to a permanent place. He has 3 forms, his third form is the most dangerous and almost impossible to counter. (you can either kill him or spare him I recommend kill).

His job is to kill certain people that had been fired from the secret-club of the garren-kindergarden.{you just got fired from the kindergarten, and now he's after you, what will you do?.
