SanessBadTomTime

I think sans is just as weak as the game says, but he uses Inventions invented by him and Gaster before the whole Gaster Incident. They were specifically designed by Gaster and Sans for use against any genocidal human that came through the underground. His telekinesis is yet another magical device. It could possibly be the supposed glove on his left hand. It seems to attach to your soul to manipulate your position. The Telekinesis is controlled by Sans's Patience and Justice. Patience as in his Patience that even though you're surviving, he will still keep attacking, and Justice, the will to destroy the monster in the genocide route you are.
