I think Sonya should rip out the victims intestines and wrap them around their throat and squeeze so hard that the head is ripped from the body. Imapale the head on a stake and just for old times sake, give the decapitated head a kiss on the cheek as the body falls to the ground in a pool of grossness. Blech!

As for Kitana, she could do a decapitation thing too but use her fans to shred the bejesus out of the victims body. mm, tasty!
