I find that wierd. Everyone, even I play better with robo-smoke than human smoke.

I rarely play as Noob in trilogy, you don't even have to be good to to win with him. There are many ways you can play him, I deffinitely don't do the best job compared to his potential but I never lost with him.

I can play everyone though.

MK1

1st. Sonya - Loved all the special moves!

I don't use anyone else in MK1.

MKII

1st. Mileena - Holy crap! The bitch is fast!
2nd. Kitana - I love the fan wave and it was nice having a move I was already used to using (Square Wave Punch)

MK3

1st. Sonya - More special moves! Kick ass combos
2nd. Sindel - The scream is brilliant!
3rd. Sheeva - Love the combos, love the ground stomp, kick ass fireball.

UMK3

1st. Sonya - See above.
2nd. Mileena - Not her best performance but still just as fun to use.
3rd. Sindel - See above.
4th. Sheeva - See above
5th. Jade - I was glad to be able to play as her. She had great specials and staff combos.
6. Kitana - Not her best performance but still up there.

MKT

1st. Sonya
2nd. Mileena
3rd. Sindel
4th. Sheeva
5th. Jade
6. Kitana

MK4

1st. Sonya - My favourite Sonya appearence she had yet even more specials.
2nd. Tanya - One hell of a kick ass bitch. I love the specials! Korkskrew Kick rules!

MKG

1st. Sonya - See above
2nd. Mileena - Mileena was really really fast. Her Tele-Kick was instant!
3rd. Tanya - See above
4th. Kitana - Same as in MKT but with MK4s excellent speed.

MKDA

1st. Sonya - Oh...my...God!!!!!!! :-O!!!!!
2nd. Kitana - She may have been low tier but she was fun to use and so graceful! I <3 Eagle Claw
3rd. Nitara - Fuckin crazy Neijin. Love the styles and specials.
4th. Frost - It was nice to play as an ice warrior only with better agility.
5th. Li Mei - I loved her specials and I love Baji Quan.

MKD

1st. Mileena - She was so much fun to use. I really liked her here.
2nd. Sindel - I don't use throws anyway so that hers is useless doesn't matter. The Kwan Dao is an animal if you know how to use it.
3rd. Tanya - Zi Ran Men is excellent and she kept all her specials!
4th. Ashrah - Great moves, love Bagua.
5th. Jade - She's really powerful. Quite slow but great to use.
6th. Kira - Nice to have Kenpo back. And Xing Yi. I love both.
7th. Li Mei - I miss Baji Quan but I like the Kunlun Dao

MKSM

1st. Kitana - She's got great combos and I love her specials in full 3D.

I don't use any of the others.

As you can see Sonya and Mileena have always been my favourite characters to use. Mileena's speed has always been useful in MK and Sonya's fury and range of specials has put her on top in every one of her appearences.

Sweet lists so far.

...awkward...

Female character exclusive usage, sounds like a guy who plays at the Break on 2D nights, heh.

Lol, the male characters in MK just...suck..

There are a few I like. Reptile, Baraka, blahblah but really they suck imo.

BAHHHH, Male Ninja's>Female Ninja's

maybe in mk3/umk3/mktril. but the rest (mks)the female hookers> the male hookers.

Even then its debatable.

Top tiers:

MK1: Sonya, Johnny Cage
MKII: Mileena, Jax
MK3: Sub-zero, Kabal
UMK3: Kabal, Human Smoke, Kung Lao
MKT: Noob, Rain, MKII, Kung Lao, Kabal, Human Smoke
MK4: Tanya
MKG: Kitana, Sektor
MKDA: Scorpion last I heard, no idea now
MKD: Bo Rai Cho, Dairou? I dunno, I really just don't care.

debatable
