MK1 - nobody, just the endurance fights.
MK2 - Mileena! ARGH! He uppercuts me without even ducking, she just hits me up!
MK3 - No one in particular, but they get harder as you go up the building. Usually Kabal or Kano give me trouble.

MK1-None
MK2-Mileena or Baraka
MK3-Sub Zero(if he is at top)

MK2= Smoke
UMK3= CPU on very hard

MKDA = Shang Tsung

In MK2 as weird as it is a good Reptile player will always gice me trouble, same thing for a very good Jax or Liu Kang player. Kitana and Mileena doesn't give me a lot of trouble anymore and I often beat them because I know who to pick against them and how to fight.

In MK1, Raiden give me trouble, particularly if it is Danadbad Raiden...

In UMK3 I don't like to face human smoke, ermac and Nightwolf

MK2: Baraka
MK3U: Jade
MK4: Jarek
MKDA: Kano

MK1 ~ Sonya

MK2 ~ Maybe Baraka (i havent played it for 9 years)

MK3 ~ Sheeva can be tough

MKT ~ Ermac, he always kicks my ass, and I have to break out robo-smoke. Jade and Noob Saibot just get really annoying 2 play against...

MK4 ~ Jax (he gives me problems in all the games)

MKDA ~ Kitana!! She always kicks my ass, Raiden too...

mk1-raiden
mk2-baraka
mk3-sheeva,nightwolf and jade
mk4-no1
mkda-scorpion

UMK3- Jade

MK:2 Sub-Zero
MK:3 Shang Tsung

UMK3 - Jade
She was BRRRRRRRRRRROKEN
that invisible/cant touch me shit is serious annoying

UMK3-Jade
that invisible thing was extremely annoying.

Stop doing that.
Next time you thieve my thoughts before i post them, i'm sending you "thret mails".

Other charcters that i found hard to beat:
Noob/Smoke in MKII
Reptile in MK
Sonya in any MK game (not sure why)
Tanya in MK4 (again, i'm not sure why)

The only fighter I ever had problems beating for a long time was Jade in MK3-MKT. Every time you would try to attack her, she would turn that stupid shield on, and sometimes she turned it on and it seemed to never stop. Then I found a way to finally beat the shield, but Jade from MK3-MKT for me.

YUP YUP YUP!! SOOO true!!! She always blinks when u use a fireball and don't even think ablout getting close because either she kicks with that glowing green kick or just combos the SHIT outta u with those goddamn 999999 hits kombos she has!
IN Mk2 Scorp was hard if u got him farther up Mk3- No one was esppecially hard... Mk4-Again... no one really sticked out MKDA- NITARA!!! I HATE YOU!!!!! Also Jax pissed me off cheesing me to death with his "Oh... yeahhh!'

Lui Kang!!! I can't jump at him cuz he shoots an air fireball! If I throw a projectile at the ##### he shoots a low fireball! If I run he shoots a normal fireball! If I manage to get close he does the damn 8-hit combo on me!
