Well
Sindel's Banshee Scream to me
If you notice, the victim look to the part of the body that been ripped.

Baraka had a nice one, so did Kenshi's sword kill

my 2nd fav would have to be ermac's 2nd its bad ass!

I think both of Mileena's are great, especially the chompy-chomp. Other good ones are both of Sindel's, Sub-Zero's frozen head rip, Kabal's twirl, Jade's torso slice, Ermac's telekinetic slam and Li Mei's fist explosion.
I was unimpressed by both of Raiden's, Dairou's and Hotaru's.

Kabal's second fatality.

Without a doubt my fav fatality is sub-zero's second fatality. I luv the way the opponent begs for their life and tries getting away.

My favorites are sub-zero's second one(it is lovely how he tortures them), Jade's first one, and Kenshi's sword one(they're both very stylish).
I'm always pissed that Raiden get's shitty fatalities. He has the whole electricity thing they could toy with.
I mean, if they want to do an electrocution fatality, why don't they make it a bit flashy, instead of the opponent just exploding? They could have Raiden calmly walk up to the opponent, and grab them by the face and lift the up in the air in front of him. He could then proceed to electrocute them. The opponent would then begin smoking, and eventually burst into flames from the heat as their skin blackens. He could then nonchalantly toss them off to the side and stare off like nothing happened.
Another One: Raiden takes out his staff and throws it at the opponent. It plows into their abdomen, and sticks(does not go all the way through). The opponent plops down on to the ground, clutching at the staff, and screaming at the sky in pain. Raiden then snaps his fingers, and a massive lightning bolt strikes the staff and turns his opponent to ash.
VARIANT: Raiden throws his staff at the opponent, but they catch instead. Raiden doesn't care, he careless says "You fool" and waves his arm, and a lightning bolt strikes the staff and kills the opponent.
Raiden definitely needs help in fatality department...they always ignore him. Maybe now with his dark side he'll get some cool ones next time around.

Definately Havik's second. Took me a while to figure out that he ate the arms. He's that fast.

noob-smokes 2nd fatality
its amusing

Kenshi's stab and slice! The way their body falls in half is so cool...
for Hara-kiri, Li Mei's decapitation is my fave.

Sub-Zero's baseball pitch fatality and Bo' Rai Cho's fart fatality. Both are funny, but both also seem like they'd be pretty deadly if it were to really happen.

Baraka's slice and dice & kira's torso throw

#5) Bo Rai CHo's fart
4) Mileena's head rip
3) Sub Zero's leg breaker
2) Subby's baseball pitch
1) Kabal's Spin (I'm Biased )

Without a doubt that would be sub's second fatality...

I totally agree. It's such an awesome fatality. The begging for their lives really adds to it.

5. Hotaru's Ragdoll Slam
4. Li Mei's Head Kick
3. Kabal's Kick 'N Slice
2. Kira's Pinned Torso Rip
1. Sub-Zero's Leg Shatter 'N Stomp

1. Mileena Sai Fatal AND Head Bite
2. Liu Kang's Possession
3. Jade's Head Impale
4. Sub Zero's Shatter
5. Li Mei's Head Kick
6. Ermac's Slam
7. Tanya's Kobu Jutsu Fatal
8. Hotaru's Slam
***They are not in order... well except the first
