Sans is sorta officially the easiest boss in the game. He dies in one hit, but yes he does dodge. The only reason he is so tough is because of the player in the genocide route. His sheer will to kill you, and his karmic retribution is all because of your actions. In a way, you're fighting yourself. You made him so strong. I also believe that Papyrus CAN do the same things as Sans can based off of this dialogue after you spare him and abort your genocide route. 'You would surely have been blasted to...' Blasted, implicating he does indeed have gaster blasters. He is waay too nice to use them though. I am not sure about Papyrus having Karmic Retribution though.. Basically, his stats show he is indeed the easiest boss in the game, but his fight is all a result of your actions.

At least that's what I thought when I played through the game. Correct me if I'm wrong.
