Jade- She should teleport behind her opponent first and shove her Bo inside his butt. Next, she lifts him up and slams him to the ground several times with her staff while he is impaled. Then, with one last slam, the victim splatters into pieces. Kind of like how Ermac's Telekinetic Slam ended up.
Mileena- First, she uses her sais to impale the opponent's eyes. The enemy screams after that while she kicks him to the ground. Her foe is still alive struggling with the pain and blindness. Then from there, Mileena unmasks herself and crawls up to him so she can eat him up from between the legs, to the abdomen (ripping out the guts), to the chest (ripping out the heart and lungs), to the neck, and then to the face. At the end, she rips out the head and shows it to the audience while the sais are gauged in the eyes.
Sindel- She screams at the opponent first, making some of his body parts, skin, and clothes tear off. Then she uses her hair to whip the body, splattering the remains all over the camera.
Sonya- First, she does her classic Kiss of Death, burning the opponent. Then as the victim burns, Sonya does her Ring Toss, making him blow up into pieces.
Kitana- First, she throws multiple fans at the opponent's entire mid-section (vertically). Then as the fans keep spinning, the victim gets split vertically in half and the fans fly off the screen one by one.
Johnny Cage- First, he does his Nut Punch fatality from MKSM, destroying the opponent's lower parts of the body. Then, he walks up to the enemy's upper body and crushes the head of the victim with one foot stomp.
Kano- First, he rips out the opponent's heart. Next, he pushes the body to the ground as he crushes the heart with his hands. Then, he uses his eye laser to dismember the dead body.
Kung Lao- First, he slices off the opponent's arms with his hat. Then, he slices the victim's body vertically in half.
Baraka- First, he slices the opponent's belly, making him/her scream. Next, Baraka uses one blade to impale the enemy at the chest and the other blade to impale the enemy at the groin. Then, he lifts up the victim over his head, and spreads his arms, ripping him/her in half while the guts are hanging down the Tarkatan's face. Lastly, Baraka eats up the guts that are by his face and continues to raise the 2 body parts up in the air with his blades like props.
Smoke- He makes a smoke screen all over the place first. Next, the players can only see the smoke while they hear the opponent gag, puke, and scream in pain while sounds of dismemberment can also be heard. Then, once the smoke screen clears, pieces of the victim's body are all over the ground while Smoke does his victory pose.
Sheeva- She gradually rips out the victim's skin one by one in a very painful, brutal way.
Jax- First, he rips off the opponent's arms. Then, he smahes the head with his two hands in a clapping motion. (A combination of his MK2 fatalities.)
