Post your fatality ideas, only one condition: they can't be impossible
Remember Hsu Hao's backbreaker in wrestling fighting style? Well, this would be a great Fatality for Darrius (if the game were realistic )
He lifts the opponent over the head (still possible with a woman or Liu ) and then drops him on his knee, with which he gives an extra kick in the backbone. You can hear the spine snap and the body lies dead. Then, if really necessary, the body can still be dropped in spikes under the stage
