PatientlyDetermined!Sans

Sans has absorbed Gaster’s piecemental soul and gained all the DT from Alphys’s lab, the amalgamates, Flowey, and Undyne.
 * Appearance: Both of Sans’s eyes still glow blue, but in a fight his right eye socket has a pinpoint of red at all times, and his left eye will flash blue and red instead of blue and yellow when Sans is angry. His hoodie sleeves have dust permanently stuck to them, but his outfit is the same as P!Sans otherwise.
 * Powers: The same as P!Sans, but with a few additions. Sans lasts three and a half times as long as Classic!Sans in a fight, but still waits as long as P!Sans before falling asleep. Sans can now summon random red bones that do 40% more damage than his AT. He can also summon one right-red-eyed gaster blaster per fight that will do 100% more damage than Sans’s AT.
 * Other: Sans is still patient, but in a more calculating, cold-blooded sort of way. Sans no longer believes in consequences as long as he can kill Frisk, but still hates hurting Papyrus. Sans tells Papyrus that all the dust on him is from cleaning an attics to pay for his tab at Grillby’s and that all the monsters are playing a really hard game of hide and seek throughout the underground. Sans now hates Frisk and only wants them to die for good. He occasionally has episodes where he remembers Papyrus dying, but they don’t affect him while Sans is fighting Frisk. Sans still likes ketchup, but now avoids it because it reminds him of the DT that pours out of him when he dies.
