W.D Gaster

W.D Gaster can still be found in the secret room in Snowdin. But the chances would be turned into 0 out of 500,600,005. W.D Gaster would use Gaster Hands in your battle against him but would strangely not use his Gaster Blaster. If you spare him he'll Gaster Blaster you but if you kill him directly you get the attack Gaster Blaster ( Prototype. ). If you use it against Sans in the end of the Genocide Run he would block every shot but in the end of the battle you'll still get to beat him.
