i think that is a pretty good idea except i would rather her just be in the game and she should be

Yeh the real joker beats Heath Ledger anyday

Final members of the MK cast:
Reptile-I like the guy. Granted, I hope to God he's not in his ninja form, but I'd be a little ticked if he doesn't show up. The MK roster seems a little light on the number of villains, so he'd fit in.
Baraka-Again, I think we could use a few more villains on the roster. He's not as interesting to me as Reptile; but I wouldn't mind him.
Raiden-To give Captain Marvel a possible run for his money. Also, he's 20x more Iconic than Jax.
Kintaro-Sub boss for the MK side.
Shao Kahn-Let's face it, would the MK portion of the Final team up be anyone else from the MK2-3 era?

Final members of the DC Cast:
Wonder Woman-Third part of the DCU's Big Three. Would be a natural opposite number to Kitana. I hope they differentiate her, Cap Marvel, and Supes a lot.
Deathstroke-Definitely a skilled fighter, with plenty of ordinance and raw power. DC also needs more villains, and the Terminator would be a good fit.
Doctor Fate or Zatanna-I'd like to see one of them, just to bulk up the magical roster for the DC side. I agree there should be a few more female characters, but hearing backwards speech over and over would annoy, so I'm leaning towards Fate.
Lex Luthor-In powered armour of course.
Mongul or Solomon Grundy- In my opinion DC needs a powerhouse villain besides the Boss character. I would probobly prefer Grundy, just because I like him more, and another genius Alien Overlord wouldn't mesh well with my next pick.
Darkseid-My pick for the final Boss.

Longshots I don't expect to see:
Zod/Bizarro/Black Adam/Zoom/Anyone else who's an evil opposite of someone already on the roster. Maybe as an alternate...

Parallax:Would make sense for a Merged Final boss. But let's face it Parallax isn't exactly a well-known villain.

Guys I don't want:
Doomsday-Just a lame gimmick to boost sales of Supes in the 1990s. Should've just killed Supes and never showed his bony protrusions ever again.
Lobo-An over-the-top parody of violent characters who became popular due to his violent nature. Irony does not a good character make.
Any more Bat-villains-Batman has the greatest rogues gallery of any comic character (barring possibly Spidey's). But two's enough for this game (I'd say more than enough).
Superboy/ Supergirl/ Power Girl/ Superdog/ Supercat/ Superhorse/ Supermonkey/ Robin/ Nightwing/ Batgirl/ Wondergirl/ Captain Marvel Junior/ Mary Marvel/ Any other sidekicks. Too similar to the hero they help.

I think that Kung lao may be in as well...or maybe raiden!

If they don't put Raiden in they'll see the community doing fatalities on them
Same goes for Reptile

my inclusions would be

scorpion

sub zero

mileena

sektor

ermac

baraka

shao kahn

smoke

blaze

raiden

MK:
Scorpion
Sub-zero
Sonya Blade
Shang Tsung
Liu Kang
Kung Lao
Mileena
Noob
Smoke
Baraka

DC:
Superman
Batman
Joker
Dash
Cat Women
Spidy
Hulk
Dr. Doom

haha the last three were not dc lol
i liked the mk side alot!
i dont really know any dc people i have always favored marvel

That's A Good Roster You Have Here,But Why Don't You Add Onaga Or A Boss Character The It Will Be Awesome.

Why Do You Start Each Word With A Capital Letter? It Is Weird...
Anyway I still just want Brainiac in the game ... It that too much to ask?

Actually,There Are Going To Be Only 20 Characters,This Is Not Fair At All !
I Thought There Would Be 40-50,Well 6 Characters Are Left Now So We Have To Wait.

Well duh, since they are crossing over with the comics. Besides, beating up a ledger look alike would seem in bad taste.

Poison Ivy would so awesome! Unique and the powers she could have. would be very cool

I doubt there's going to be any more Batman characters though.

Heroes
Martian Manhunter
Red Tornado
Doctor Fate
Hawkgirl
Zatanna

Villains
Darkseid or Doomsday
Sinestro
Bizarro
Deathstroke
Poison Ivy
Harley Quinn

Brainiac would be cool, but dude the words starting with a capitial letter deal you do it 2 lol.

Not every word :o
I guess?

As of this point, Kotaku's DC character description list has been 100% accurate:

Prototypical Super Hero: Superman
Speedster: Flash
Mystical Super Hero: Captain Marvel
Amazon Queen: Wonder Woman
Sexy Villainness: Catwoman
Crazy Villain: The Joker
Masked Vigilante: Batman
Military Superhero: Green Lantern
Ninja Villain: Deathstroke

All that's left is the archvillain, and the epic villain.

I think the final two DC characters will be Lex Luthor (archvillain) and Doomsday (epic villain).

On the MK side, we've got:

Jax
Kano
Kitana
Liu Kang
Raiden
Scorpion
Shang Tsung
Sonya Blade
Sub-Zero

Goro should definitely be there, and the final slot will either be Reptile or Cage I'm sure.

And of course, the merged boss should be Shao Kahn / Darkseid.

Ha ha. Well I was right so far about the MK side being the cast of MK1 plus a few from MK2. The original magnificent seven + Reptile, Goro, and Shang Tsung are the MOST iconic after all. Shao Khan, KItana, and Jax are also the only non-mk1 characters to appear in the first MK movie, which while not 100% canon accurate, was certainly iconic-chars only. Kano HAD to make it he is one of the original bad guys and he's a hardcore badass. Now I need Cage. I have to punch Superman in the nuts, he's had it coming a LONG time. I love Reptile but although he was the original secret character, he might not make it but here's hoping. They should definitely release Mileena as one of the first DLC because the game really needs more female fighters to balance it out. She's only slightly less iconic than Kitana but with Kitana in we need Mileena at the very least as DLC. Here's Hoping.

MORTAL KOMBAT

1. Sub-Zero (+)
2. Scorpion (+)
3. Raiden (+)
4. Sonya (+)
5. Johnny Cage (?)
6. Kano (+)
7. Liu Kang (+)
8. Reptile (?)
9. Shang Tsung (+)
10. Shao Kahn (?)
11. Kitana (+)
12. Noob Saibot (?)

So it down to the final four

1. Johnny Cage
2. Reptile
3. Noob Saibot
4. Shao Kahn

Ok, guys, this is what I think the finalized roster to MK vs. DCU is gonna be, based both on confirmed characters, and my own hunchs.

-Mortal Kombat-
Liu Kang
Scorpion
Sub-Zero
Sonya
Kitana
Shang Tsung
Jax
Raiden
Kano
Johnny Cage
Mileena

-DC Universe-
Superman
Batman
Wonder Woman
Flash
Green Lantern
Captain Marvel
Catwoman
Joker
Deathstroke
Lex Luthor
Circe

I just figure it'd be a toss-up, but who knows? If we HAD two bosses for each side, I'd have Shao Kahn for MK, Darkseid for DC.

Bryon

mk needs a couple of more girls, as of now theres not enough, but yeah thy need more, frost and jade, or jade and khameleon

For DC side, what do you guys think of Lady Shiva? I'm not sure if most of you know her but I think she will be perfect for the game. She's a martial arts grandmaster/sensei and an assassin-for-hire. She's also trained Batman once. You can read more about her here: Lady Shiva

She'd be awesome and hey if Deathstroke and Captain Marvel made it in.

i think it is very likly that mileena and retile will make it. they have to have more villians and i dont think they are only going to have two girls on each side. i beleive that at least one of these two are going to make it :)
