Countless deaths and many save later; Frisk was finally getting the edge, forcing Sans onto the backfoot. But right when the human was about to deliver the final blow, a savior dropped from the skies. Snatching him away from such fate and bringing him across spacetime into a new world. A new life. However, he is not alone, as the threat of humans arrives in this foreign land as well. Their blade thirsting for blood.

With nothing to his name and bringing along the scarf to remember his brother by, how will Sans go about in this alien world?

An Undertale/Mlp crossover takes place in the Genocide route of the game. Spoilers for The Undertale Game.
