ALL of them!.. No seriously.

Catwoman for sure

Well, since my two faves are Nightwing and Catwoman, it will probably be those, but it depends on the character gameplay. ^^
One of the other characters might surprise me.

Aquaman .....when he's confirmed.

Catwoman will be my main as she was in MKDC.

Confirmed:
1. Bane
2. Green Arrow
3. Deathstroke

Unconfirmed:
1. Gorilla Grodd
2. Martian Manhunter
3. Swamp Thing

Of the confirmed:

1) Harley (New gameplay makes her look exciting)
2) Catwoman
3) Nightwing
4) Green Arrow

Non-confirmed

1) Raven
2) Aquaman

It depends on a lot of factors. Aquaman and (If he's in) Blue Beetle are major candidates for being my main. I'd say the runner-ups are Shazam and (if she's in) Raven. Despite all the shit I talk about Lantern's costume, he's also very high on my list of potential-mains.

Despite Blue Beetle being in my signature, I don't favor him more or less than Aquaman. I just figured since Aquaman is a guarantee, I want to endorse a character who isn't already a lock for the roster. However, if both characters end up being bandwagon characters because of their tier, that's a huge a strike in my book. I would hate for those two to be the Sonya and Kabal of this game.

Ultimately, it all comes down to style, presentation, concept, and tier.

Superman.

Superman no matter what.

Else:
- Wonder Woman
- Catwoman

Unconfirmed:
- Swamp Thing
- Aquaman
- Animal Man

Am I the only one who's going to main Grundy? Certainly looks that way.

I don't use grapplers in fighting games... (Astaroth is the only exception.)

I'll give all the characters a go and once i got a feel of them i'll see who i have the most fun playing as and focus on said character. I'm excited to see who that might end up being.

That's very true. Hal Jordan being my favorite DC character, I haven't seen any gameplay of him. While in MK9 Baraka is my favorite and he plays like crap (Still use him occasionally though). I mained Kano. It still worked out because I love Kano and I dug his design.

We'll have to see though. I'm sure Jordan won't play too sloppy. (Watch him be the Kung Lao of Injustice -_-). Oh, and I forgot about Sinestro. If he's in it, I'll see what I can do with him. If one Lantern doesn't work out, I'll always turn to another. Except Zilius Zox...

Neither do I. (Can't stand Zangief in SF) But Grundy just looks fun. The way he just slams opponents over and over again. As of right now, he's the only character I have any interest in.

Most likely I wont end up maining Superman because that's how it usually ends up happening.

The whole time before MK9 came out, I thought I was gonna main Noob and Shang Tsung, got the game, and realized I was terrible with them.

Besides Wonder Woman, obviously:

PRIMARY HOPEFULS
1. Harley Quinn
2. Catwoman
3. Bane
4. Green Lantern (but I shall view him as John Stewart!)

SECONDARY HOPEFULS
1. Green Arrow
2. Solomon Grundy
3. Nightwing
4. Cyborg

IF THEY MAKE IT IN
1. Sinestro
2. Poison Ivy
3. Aquaman
4. Ra's Al Ghul (I think that's how you spell it)

I kinda feel the same about Bane. I never liked him as a character, or grapplers in general, but he looks pretty fun to play, so I'm going to try him out. That Drop kick and that anti-air grab looks so godlike.

I'd say these will probably be in my top 5 (of those currently confirmed).

1. Captain Marvel
2. Flash
3. Joker
4. Luthor
5. Nightwing

def interested in Cyborg

Superman so I can punch every character in the game to space and back to earth lol now that's gonna be hilarious

Also this game better not be region locked on PS3 like MK2011 was. Fuck that!

I wanted so much to main Shang Tsung in MK9. I just can't wrap my head around him.

I like Grundy and Bane. I also hate grapplers so it depends how difficult it is to initiate grabs during combat. Otherwise their pressure based offense seems right up my alley.

Batman is also high on my list. He just seems overall(so far) to be the most well rounded character.

Captain Marvel was a blast in MKvsDC, so if he's half as fun here, I'll probably use him a lot.

Swamp Thing is the character I want most in this game, so I would absolutely put a lot of effort in to him.(here's hoping it doestn't turn out like Shang Tsung)

I'm planning to master Deathstroke but mostly use him on just serious matches or when i start losing.
But for most of the time, I'll probably be casually using Harley Quinn, mostly because of the recent Battle Arena video. Solomon Grundy has also intrigued me so I'll be trying to figure him out, as well as Green Arrow, Batman, and Catwoman. I wanna see the rest of the characters in action before I make up my mind though... But I do know I will be maining Slade for sure.
