Sadly, Outer Sans sacrificed him self for classic and died in the hands of killer in the movie Underverse.
Outertale Sans is similar to classic Sans, the Supporting Character in Undertale.
Sans wears a hoodie that has fluff inside it everywhere, with two yellow stripes and yellow sleeves, and he wears fluffy slippers with stars.
Sans also has a supporting, caring personality. In Outertale, Sans cares for his love of Frisk much when Frisk supports mercy.
However, when Frisk does a Genocide Run, Sans' personality changes. He becomes concealed. Like Undertale Sans, he judges the player very harshly.
Sans also likes puns and tells them so much to the point that it annoys his younger brother, Papyrus.
Outertale Sans is also sometimes depicted as a bit shy.
Sans is proud of them for not killing anyone and will try to help Frisk SPARE Asgore. Eventually, Sans shows Frisk the timeline jump machine and tells them about Gaster.
G E N O C I D E
Just like in the Undertale Genocide route, Sans hates them for killing everyone (especially his brother).
W. D. Gaster
Sans has some connection with W.D. Gaster. He is the only one who remembers him and his brother Papyrus now, he was Asgore's scientist.... Sans played W.D. Gaster in his own creation to protect his brother and that's how they grew up on Stardin.
