This is a pretty sick and "twisted" fatality idea from yours truly...
Kabal takes his hooksword (only 1, not both), from the hook shaped part of the sword, Kabal stabs the opponent through his mouth and out from the back side of their head comes out the hooksword. The opponent screams in pain, holds his head as he falls to the floor on his knees, Kabal grabs the hooksword on each side with each arm, and he twists the head all the way (a 360 degree turn).. as the neck snaps, Kabal pulls the head right off!!! KABAL WINS! FATALITY..
