MKD - Bo Rai Cho
MKA - Kreate A Fighter

MK(2011) - Liu Kang

I know it's a bit weird to list the KAF for MKA... but honestly I hated playing MKA with anyone but my KAFs. I loved MKD so much but what they did in MKA fucked up all the characters I was good at and I was (and still am) very unwilling to try and figure out how to play as anybody.

Now to me, MAIN means your ONE PRIMARY character. But if we're all listing secondaries then here's that list too.

MK1 - Sonya
MK2 - Mileena
UMK3/MK3/MKT - Sub-Zero (unmasked)
MK4/G - Reiko
MKDA - Quan Chi
MKD - Ashrah
MKA - Kreate A Fighter..........
MKvsDC - Liu Kang
MK(2011) - Ermac

Please note, that these are not necessarily my personal favorite characters. They're just the ones I happen to best at game play wise.

MK: Kano.
MK2: Jax.
MK Trilogy: Kano.
MK Gold: Jarek.
MK Deadly Alliance: Frost & Kano.
MK Unchained: Frost & Darrius.
MK Armageddon: Frost, Daegon, Moloch, Kano, Darrius & KAK Ruby.
MK vs DC Universe: Kano & Shazam.
MK 2011: Kano & Freddy Krueger.

If my memory serves me correct:

MK1: Sub-Zero
MK2: Sub-Zero
MK3: Stryker
UMK3: Stryker
MKT: Stryker
MK4: Liu Kang
MKDA: Scorpion
MKD: Scorpion
MKSM: Baraka
MKA: Scorpion
MKvsDC: Deathstroke
MK9: Scorpion

I dont think main means just one. I have multiple mains in each game and then my secondarys are chars i like but dont use very often or use just for fun. Anyways...

MK1- Sub Zero, Rayden
MK2- Liu Kang, Reptile, Sub Zero
MK3- Sub Zero, Sektor, Liu Kang, Kano, Nightwolf
UMK3- Reptile, Sub Zero, Sektor, Liu Kang, Kano, Nightwolf
MKDA- Reptile, Sub Zero, Mavado, Scorpion
MKD- Liu Kang, Sub Zero, Noob/Smoke, Ermac, Jade, Tanya
MKA- Liu Kang, Noob, Ermac, Sektor, Mavado, Tanya
MKvsDC- Liu Kang, Baraka
MK9- Reptile, Liu Kang, Sonya, Sektor, Cyrax

I havent really played MKT or MK4/G but once each but ive stuck with some of the same chars almost always. First off i dont like liu in mk1 but he became fav of mine since mk2. Raiden i dont play with in any mk game except mk1 kinda like how i dont really use scorpion except in mkda. MKvsDC i only had for two weeks. In that time i mained liu and played 200 matches online with him, then was learning baraka to main as well. And sub zero you may notice i mained up till mka because i dont like him or reppy in mka, and i still havent liked sub since. Subby looks awesome in mkx though so i hope ill enjoy playing with him. And yeah i dont know why but ive noticed i seem to main more chars than most other ppl.... Like with mk9 most ppl dont know more than 3 chars really good, whereas i truly play with 5 mains on a reg basis.

I never really got into the game play of MK until MK9 so I never really had a main until then. Although Ermac was my favorite whenever he was playable.

MK9: Cyrax, Sektor, Johnny Cage, Jax

I learned to play like half the cast but I was best with the above.

MK9: Mileena

Yup.

I started with MK2; here we go:

MK2: Mileena, Baraka, Cage
MK3: Sonya , Kano
UMK3: Sonya, Kano, Mileena
MKT: Sonya, Cage, Kano

MK4: Sonya (HAGA-GAAH! GETOUTTAMYFACE! VOLTAKIII! FUCKOFF!), Tanya (just cuz she fucks over Liu Kang), Fujin
(Although I'd often pick Reptile, even not being any good, just for a chance to see dat Head-Eat fatality tho. Also, can I just admit real quick, that sudden HISS/GROWL thing he did in the intro, used to creep me the flying fuck out? Like, seriously, I couldn't watch that. Little me wuss scurred).

MKDA: Sonya, Cage, Cyrax
MKD: Mileena, Jade, Havik
MKA: Sonya, Shao Khan (lol)
MKvsDC: Sonya, Joker
MK9: Sonya, Kano, Mileena

MKX: Your mom.


I always have the primary go-to-, first-pick main, and 1-2 other characters that I strive to be just as good with, for the sake of not being TOO predictable (read:boring) of an opponent. Not ashamed of my pattern, though. To this day, hearing the ominous select-screen voice shout "Sonya" is like a secretion of endorphins to my brain.
