From what I hear from many people in the forums, the top fun characters to use appear to be (no order):

* Superman
* Flash
* Sonya
* Catwoman
* Liu Kang
* Green Lantern
* Deathstroke
* Scorpion

I haven't played the game yet, but from what I've seen, some of those might also be my faves (plus Joker, Rayden, Kano and Baraka among a few others), specially Sonya, Catwoman and Flash, who look to play fantastic. Same with Liu Kang.

I use Liu Kang and Baraka

The 3 in my sig for competitive play. Everyone offline, for Arcade.

Green Lantern online. For some dumb reason last night I went up against that Ed guy, the number one player on Xbox Live. He royally handed me my ass with Scorpion.

Scorpion easy to use. He has an easy 4 or 5 hit combo, like flash. 1, 1, 3,3 or sumn like that.

And anyone who says flash is easy to use, buck that. Because when you got some one standing there blocking the hole game, you got no summon hellfire, you got 1 of 3 things with him. A jump kick in the air, or grab / close combat. Flash is great though for catching people who spam their specials. Scorpion it kinda sucks because of his spear, but just Sidestep that non-sense.

Joker is one of the main reasons, among others that I bought this game. So i wanna get good with him.

I'm serious though, this guy Ed(some number) is ranked number one, and for some reason I was paired up with him on Xbox last night. Don't know if he is still ranked number one but he was the best player in the United States at least.

The Man with the S on his chest.

so far my favorite character to use is captain marvel with kitana in a close second.

My favorite characters are:

1. Sub-Zero
2. Superman
3. Sonya
4. Scorpion
5. The Flash
6. Batman

Batman is my main guy to use.His combo's for me just seem easy and I like the way he moves and his special moves.

Batman! duh duh duh duh duh duh duh duh duh duh Batman! ( batman music)

No, but really, i don't think he is the best, but he is very fun to play.

My fav so far is the joker I was having a really good run with him Id beaten at least 15 sum people in a row using him and his been my fav so far I also like 2 use raiden 2 but suprisenly I havent played much with Sub-Zero.
