Fatalities
The Point (Johnny Cage)
Nightmare pulls Soul Edge off his back and shoves it into Johnny's gut. Reaching around to his back, Nightmare pulls Johnny down the blade, bisecting his body. Johnny looks up as Nightmare grabs his head and squeezes it into a bloody explosion. He swings his blade to the side and Johnnys top falls to the ground.
Bloody Good Time (Raiden)
Nightmare swings Soul Edge and slices off Raidens knees. He swings again and slices off one arm before doing the same to the other. He sheathes the blade and starts punching Raiden in the face repeatedly, breaking his nose and blacking his eyes. The screen becomes tinted with blood until Nightmare ignites his demon hand before punching clean through Raidens chest before pulling out and kicking the body away.
X-Ray
Soul Wave (Kano)
Nightmare swings Soul Edge and slices across Kano's chest, breaking the ribs making them puncture the lungs beneath them. He cocks his fist back and punches Kano square in the jaw, breaking several teeth and cracking the skull. He kicks Kano to the ground and stabs down, destroying the stomach.
Victory Pose
Nightmare sets Soul Edge ablaze and stabs it into the ground. The fire spreads around him as he laughs like a mad man before staring at the screen.
Ending
Standing over Shinnok, Nightmare shatters the amulet that confine the Elder God. The final shard in it fused with the blade, and Nightmare transformed. All the souls absorbed by the amulet merged with, and Nightmare lost control. In a wild frenzy, Nightmare slaughtered anyone in his way. Inferno ruled this world through his vessel, and Siegfried was forever lost.
Sorry for the long wait. I've been busy with my life and other stories. For the next character, we do down into hell.
