Video showing all off-guard/betrayal kills in Undertale. These are kills where attacking a monster at its most vulnerable moment will kill it in one hit. Experimental quality. 0:00 Toriel's kill. |--| 3:15 Papyrus. 9:18 Shyren (despite the low damage, this actually is a special kill, normally it'd only do about 50 damage and it wouldn't kill). 10:21Royal Guards. 12:58 Muffet. 14:23 Sans, who does this to YOU.
