Word.

Lets what i can conjure up:

Ermac:
Head- Should be a solid metal Mask of a Face with his Green "Hado" Energy shining through the eye sockets.
Body- A Battle Mage type uniform

Goro:
Shokan Royal Battle Gear (Helmet, Chest Piece, Gauntlets, Grieves & Pauldrons)

Kano:
Head- A cybernetic Eye patch (so he can still emit laser shots)
Body- A sleeveless biker vest, Armored undershirt, Cargo Pants w/ Knee Pads already attached to the pants. (knives on Boots and Grenades on Belt)

I actually really want to see Cassie in an outfit like Lana Kane's in Archer.......

Cassie: MMA gear.

Sub-Zero: Same as costume in issue 1 of the comics.

Scorpion: Non-demonic Hanzo look (similar to the one we see in the comic).

Kano: Bald, MK1 style.

D'Vorah: Kreeya style outfit from Conquest.

Ermac: I want that concept art for him that was 'leaked' a few months back.

Raiden: Dark Raiden. Too easy

Sonya: Bridgette Wilson skin (or just the outfit), her MK3 design, and her MK:DA General alt, a variation of it with short-sleeved military shirt and a skirt, and a musketeer attire (not a skimpy one, though I wouldn't mind).

Ashrah: a white nun robe, a fully white Sheik-like attire (Sheik from the Zelda games, I mean) with bandages on her arms and legs and an hood but no mask. The second suggestion might work for Kitana and/or Mileena too, with some tweaks.

Sareena: What the female Cenobite from the first two Hellraiser movies wore. I wouldn't mind her being bald, either, or an hairstyle similar to Zorg's from the Fifth Element (with the white streak, of course). This whole design would work for Jataaka and Kia too.

Stryker: Original chubby MK3 self, MKA alt with some changes, an unbuttoned and short-sleeved police shirt, shorts, and police boots, a Miami Vice-styled unbuttoned suit with nothing underneath the vest, a dark-blue police uniform, and leather getup based on the first Mad Max movie.

Nightwolf: Tribal (Wears nothing but a featherly hat, Native American thong, and sandals), dance regalia, buckskin dress.

Smoke: human and wearing his MKD alt's outfit and a ninja mask instead of the cyborg helmet.

Sindel: a fur coat and a dress worn underneath.

Ferra/Torr: Outfits based on the similar duo from Mad Max 3, a Tasia one for Ferra and a Tremor one for Torr. Both characters' alts should be individually selectable, allowing for combinations.

maybe give kitana a plaid flannel shirt and some hoop earrings.

I like samurai raiden with his hat on his back.

Torr needs a carrot top skin, turn ferra into Gilbert Godfrey

Li Mei: Street fighter (if you know what I mean), and Oriental Kimono.

Sonya: Military camo attire, or a camo tanktop for her upper body and military pants.

Jade or Kitana: Cave woman, clad in leopard skin, and with a wooden lance instead of a staff (for Kitana's mourning variant).

Jax: High-top hair that resembles a brush.

Johnny: Here's Johnny! As well as a superhero-themed outfit with the letter C as a logo, and for a third alt, a white robe with longer hair.

I just want this

I want a "Kasual" costume for Cassie. Something similar to what she wore in the comics, the only thing I would add is "CAGE" stamped across the back of her shorts.

Human Sektor and Cyrax: Predator-like design where they're almost completely naked, wearing nothing but the cyborg helmet and armored shoulder pads, wrist gauntlets, armored thong with the cyborg belt (from their MK3 designs) and metallic boots.

Johnny: Shaved head ,white skeleton makeup all over his body, the rest painted in black, a black speedo with white skeleton crotch imagery, a red headband and his shades, as always.

Kobra: Goofy cobra suit (and if he got the Kalo sticks back, they'd look like cobra snakes), and Sonya's MK1 outfit.

Cassie needs dominatrix alt. as does Ferra

Has there even been such a thing as a SECRET alternate?

Kenshi: original red-black outfit
-Classic samurai look
-Alternate PSP Mortal Kombat 9 outfit
-Neo-like outfit
-Upper body naked

Raiden: Long Grey Hair Deception costume

Sub-Zero: Unmasked Version

Johnny Cage: MK1 "Bloodsport" outfit

Reptile: Human form (allways prefered the Lizard in disguise concept)

-D ́vora: Long Raincoat concept as seen in the last trailer

Prior to seeing Mileena's outfit in the comic, I would of said the same. But I honestly think the comic tops this one.

Flesh pits Mileena?

I would want Scorpion to wear Hayate's shozuko from Dead or Alive, the red one specifically. I think it looks amazing. Anything similar to that would be great. Maybe just black.

I remember there was concept art for Scorpion where he had on a black ninja garb but the yellow color was demon blood splattered all over the outfit. Let's see that!

After watching Once Upon A Time yesterday, I totally want a Cruella Deville alt for either Sindel or Sareena. It's a pity neither are that likely to end up in the game (as playable characters, anyway).

Meat.
