Sans "Sans Gaming" Undertale is the main protagonist of G-Force 2, The post Made-In-Heaven version of Jotaro Kujo and the designated pilot of Evangelion Unit-01. Much of the story of G-Force 2 centers around San's personal struggles, both with piloting Eva and with his relationships with others.
He is the son of "deceased" Gehirn bioengineer Freddy FatBear and Nerv Commander Brian Griffin. After Brian's apparent death, he was abandoned by his father and lived for 11 years with his brother Papyrus Undertale until he was summoned to pilot Eva-01 against the impending Negro threat. He initially lives with Coconut Fred although they are later joined by Fat Mama.
Like all other members of the Undertale family, Sans has a small cock-shaped birthmark on the rear of his left asscheek, close to his anus; and has tattooed on top of his left forearm an image of his bent penis superimposed with a downward-pointing dagger, to signify the events of volume 8 when his genitals were stabbed with a dagger. He is also a browno and wears a blue hawaiian shirt and a gay ass apron to distract from this.
Sans is a damaged but compassionate individual. The death of his mother, and especially his abandonment by his father have left Sans with difficulties in his relationship with others, (especially Fat Mama) and with himself. This trauma eventually leads to him developing his stand "Despacito". As of Season 4, he has learned to be at peace with himself and now lives in a quiet village in Detroit with his pet dog, Daddy Yankee.
