A bit of blood flows down though his mouth. (Phase 2) There's no difference in his appearance except that he has a red slash in his torso showing that Frisk attacked them. (Phase 1) Nothing differs Sans here from his Original Counterpart except for his dialogue. He then trusts Frisk to do the right as they turn to their Save Point. Touched, Sans does not kill them and instead claims that he is proud of them. When Sans offers Frisk mercy, Frisk will spare him out of remorse. Sans then looks like he's about to stop smiling for once, but turns to dust and ashes before he could do so. As he looks like he hopes for the better to come, Frisk manages to hit him a second time. Eventually, Sans finally runs out of magic. Not only that, but he then blindly attacks as a maniac, hoping to put an end to things once and for all. He allows that certain someone to take over, disfiguring his face and forming a crack by the right side of his head to his eye. Sans soon gets tired again from attacking and blocking, falling to the ground, waiting to die, but when he is attacked, he takes no damage. Refusing to let this second chance go to waste, he summons a small bone to use as a shield against your attacks, his eyes become hollow circles and he begins the second part of the fight. Sans then becomes confused as to why he hasn't yet turned to dust, checking his hp to see he has a small fraction of health left, allowing him to stay alive. He then begins to explain why he acts so lazy and is so nihilistic, it's due to the fact that the anomaly would just erase it all in the end, so there was no real point to ever giving anything a real effort. If you choose to fight, Sans will get hit, falling to the ground as he begins to bleed from the scar. With no other choice, Sans fights them, now no longer holding anything back, using every one of his abilities to its fullest, including his new orange bones, but in the end, he becomes tired from dodging, giving Frisk the choice to give mercy. Now fully convinced, Sans readies himself to confront Frisk after being taught a new ability, it being orange attacksĪfter killing everyone, Frisk is confronted by Sans in the Last Corridor, Sans tells them everything he is aware of and tries to guilt-trip them, but sadly fails. Skeptical at first, Sans refused to believe so Gaster then resurfaced past Genocide timelines throughout Sans' mind. Sans recognized who this was while he was informed of Frisk's intentions to forever use monsters as their puppets and slaughter them. On the 30th Genocide Run, Sans was napping at his sentry station, as usual, when a figure appeared throughout his fantasies.
