I have mastered all the characters if you are talking about combos and stuff like that,I completed konquest in a week that's not too bad,and I know all the combos from my head.

I have only mastered CyraX and Frost. I have mastered their special moves, combos, and always do their fatality with no problem

I literally own the computer or human with Sub-zero or Nitara.

i have mastered everyone but i am extremely good with scorpion, raiden, kung lao, quan chi, shang tsung, sub zero and kano and kenshi.

I've only mastered Scorpion. I haven't waisted my time trying to master others little by little, instead i master 1 charector to know all i can and all that there is to know.

Its not all about how good you are with your character, but how badly your opponent has mastered his. I win on other's mistakes.

I've mastered everybody, but characters that i'm INSANELY good with are Scorpion, Subzero, Kenshi, and Nitara.

BTW, i'm horribly cheap with Drahmin.

I'm really good with Shang Tsung, Hsu Hao, and Scorpion. I think the difficulty levels set on the characters are way off on some of them. Like, Shang should be a 1 or 2 and Sonya should be like a 3...

Heh, kinda funny how people are listing off a lot of top tier characters and saying they've "mastered" them. I suspect this is because of the easier wins people gain with the likes of Scorpion and Shang Tsung.

Anyway, the concept of mastering characters in MK:DA is kinda shallow. Just memorizing and abusing their 3 most powerful combos, follwed by throwing down a memorized fatality is pretty much it...eh nevermind.
But if i was to choose a character, i might go with Kung Lao...but i'm really not sure i have at all, because i didn't stick with the game long enough to know, i guess.

"Its not all about how good you are with your character, but how badly your opponent has mastered his. I win on other's mistakes." Yup, thats pretty much it Bleize.

Also, when u say "Master", i hope u mean in a way that you know every attack and counter attack, with all the combos, knowing how to do them and exactly how to time them, and most importantly, knowing everything so good, in a way, you hunger for more moves, combos, etc. because that is how i feel with Scorpion. i feel as if he has no moves at all and that i have to combine and invent some of my own combos. That is what i define "master" as. But of course i am very familier with Kung Lao, Sub zero, raiden, Cyrax, and Reptile.

i also believe that your skill level will be the same with any character. Because there is a fighting style of your own that seperates you from other players. for example: 2 scorpions will fight against each other, but the player with better skill will win.

and the last thing, belive it or not, every player, i believe is balanced. Everyone is equally set to win and loose. (strengths, weaknesses) Mortal Kombat is, and truelly will be, the best fighting legacy of all time.
