He can also apparently skip time/space during his attacks... Sans also isn't added to your kill count, but defeating him auto lvs you up to lv 20 (even if you hacked the game and your lv was lower than 19 when you faced him).

After Sans is defeated, when you face Asgore, the Mercy button is missing...
