The Dragon fatality comes back in MK4/G and is much, MUCH more violent. Not only does it bite the opponent, but it swings them around then brutally slams them to the ground.
The Hat Tear has to be one of the most gory fatalities in MK history. Very few rival how amazingly violent that one is...
Johnny has three fatalities, but two are pretty much the same. The fatality not show has Johnny knocking multiple heads off the opponent(a tribute to the bug in part one that allows you to do this)
Reptile's Friendship is exactly like the other ninja's, thus just watch Scorpion's and imagine it's "Buy a Reptile Doll" rather than Scorpion Doll.
Fatality - Atomic Snowball
Fatality - Ice Shatter
Friendship - Sub-Zero Doll
Fatality - Kintaro
Fatality - Inner-explosion
Fatality - Soul Suck
Friendship - Rainbow
Fatality - Deadly Kiss
Fatality - Fan Chop
Friendship - Cake!
Fatality - Arm Rip
Fatality - Head Smash
Friendship - Paper Dolls
Sub-Zero's Friendship is exactly like the other ninja's, thus just watch Scorpion's and imagine it's "Buy a Sub-Zero Doll" rather than Scorpion Doll.
Shang Tsung's nut-crunch pose is the best of the lot, absolutely hilarious. He's also the hardest character to perform the move on.
Kitana can be an absolute bitch with the right player. For instance: If you can catch someone in the corner you can perform quite a few devastating combos with her "fan lift" move.
Taking the Arm Rip fatality a step further, in MK4/G Quan Chi rips opponent's legs off...then proceeds to beat them with it.
Fatality - Sai Stabs
Fatality - Bone Storm
Friendship - Flower Drop
Fatality - Blade Chop
Fatality - Impale
Friendship - Present
Fatality - Toasty
Fatality - Spear Rip
Friendship - Scorpion Doll
Fatality - Exploding Uppercut
Fatality - Electrocution
Friendship - Kid Thunder
In the arcade version, you could perform the Sai Stabs fatality from behind the opponent, resulting in Mileena ripping up their back and ass. It was pretty funny.
A lot of people ask if my girlfriend's cat is really named "Baraka", and if so, was he named after this character. He is really named Baraka, but not after MK's angry nomad...he's named after the poet "Amiri Baraka".
Note: Scorpion has a third fatality that is very similar to the Toasty, but can be performed anywhere on the screen.
In the Genesis version of MK2, someone at Probe had the great idea of putting one of the employees in a special fatality. Called "Fergality", it was a monument to Probe's ever-disgraceful use of resources.
Kombat Tomb Spikes
The Dead Pool
The Pit II
Babality
Holding "Down" on the controller after sending someone into the spikes will make their body slide off of them, falling to the ground.
In the arcade and SNES conversions of MK2, holding "Down" and "LP" after knocking an opponent into the Dead Pool resulted in the skeleton saying "Aw Boy".
The Pit has shown up in every MK game except MK: DA.
The Babality is exactly the same for every character, it just results in a slightly different picture.
