undertale:corrupted underground!(sans)

Description: sans used to be a humerus skeleton,he made puns that annoyed many and made some laugh sometimes,nowadays,he welcomes the days with a less "humerus" tone,many years have come and gone scince frisk left and the underground has become cold as hope for freedom dimishes,now he has to take the job of a royal guardsman in order to help papyrus go about his day to day life.his scar that goes up his right eye was caused due to alphys injecting DT into his eye causing his eyes to permaintly glow red and blue,he makes barely any puns anymore and the side effects of the injection removed his emotions and feelings so he would not feel guilt for killing humans that fall down and exit the ruins into snowdin,he cares about papyrus deeply and tries his best to prevent papyrus from caring about humans and brutally punishing him if he tries to help any humans,so the releationship of papyrus and sans is teneuius at best,he currantly works with alpheys on a new device that will hopefully open a hole in the barrier allowing monsterkind to escape the underground,due to the DT injection,he can now do 7 damage with hes KR and can use red and blue bones and hes gaster blaster deal more damage,and they look more menacing and more dangerus,with large horns and sharp jaws and glowing red and blow eyes,despite the fact he feels nothing,he can still made to feel again by someone who can reason with sans bring him to his senses......if there is any hope for him left in this dark,twisted underground,and one more thing,he is also a royal scianest as well*
