I always loved Scorpion's alternate costume from Deception. It was like an updated version of his MK4 outfit

Sub-Zero MKD armor and MK3 maskless scar Kuai Liang.

Right on man, Reptile's MK4 costume is the one I want to return the most. I've mentioned it a few times in different threads over the last few months. I think his look in that game was a perfect intermediate between his human ninja palate swap and the full on lizard from MKDA.

Another costume that I want to see return is a very controversial one; Sub-Zero's Shredder costume from MKD. It seems that the majority of people on this site don't like it, but I always loved that look. Something about the helmet just screamed "Grandmaster of the Lin Kuei."

Bald kano from mk 3

NOT MK1-MK3 Ninja Retros.

Alright if they're bonus costumes in-game or a cheap-ass pack WITH the vita exclusives..fine. But if it's DLC again it's just as bad as as releasing the same DLC character as DLC again in MKX. Plus what would you even alter about it for the different variations?

Anywho I'll stick to confirmed characters and heavily hinted ones:

Scorpion: MK:DA Alternate Costume.
Sub-Zero: Cyber-Zero, Shredder-Zero.
Raiden: Dark Raiden.
Kano: MK:DA Alternate Costume.
Goro: Kintaro.
Quan-Chi: MK9/MK:DA. He's only got 2 major looks really.
Sonya Blade: MK4 Sonya.
Kenshi: MK9.
Johnny Cage: MK4/MK:DA Alternate.
Shinnok: Armageddon Alternate.
Reptile: MK: SM (With the 2P Human Look), MK:DA Alternate

Kenshi MKDA, Reiko alt. Armageddon (a revamp of his MK4 look), Dark Raiden, Scorpion MKD, and I may be forgetting others.

Goro's MK4 design, and his armored alt from MKD with much more detail. The props from Motaro's MKA alt would also suit Goro nicely.

Kano's MK1 and 3 outfits, and as someone already said, Kano should be bald for the latter. Completely hairless, even.

Quan Chi's first outfit.
Both of Sub-Zero's MKD designs.

Monster's design for Scorpion. If he didn't return as his own character, of course.

For the 5 returnees

Kano: MK1 or MK3
Quan Chi: MK4
Sub-Zero: MKDA main or alt
Scorpion: MK4 (skull)
Raiden: MK1

None. No retro costumes, all new. Wouldn't mind an unmasked one for SZ based on his MK3 design

Subs MKDA main would fit this game perfectly, as to characters got older.

I doubt several of the characters i'll mention will be in the game, but if they are I want these costumes:

Kung Lao MKDA primary. It was one of my favourites redesign from that era, it's a shame it wasnt his alt in MK9. Oh, and that version of his classic costume was also better.

MKD Sub-Zero.

MKDA alt scorpion

MKA alt Shinnok (the one with the blue coat). I hate all his other looks, but that one is simply amazing.

MK4 reptile alt. Ninja costume, reptile skin. Also classic human reptile.

MKII Baraka. More than a costume, this is about his physical appearance, I don't know how to describe it, but he was more... Slender? I always thought that was the most frightening look he's had.

MK3 nightwolf

Zombie Liu :P

MKDA raiden

MKD Sub-Zero's main is a total disaster. Doesn't really fit into MK. The TMNT designers/creator's should sue, lol.

With the joke aside, the answer is no.

I'm all for classic costumes, they have always been my favorite, although I will admit Scorpion and Sub-Zero's new costumes are probably my favorite looks for so far (Excluding their MK1 and MK2 costumes)

Shinnok's primary and alternate from mka. But more updated and sleek.

Well Mileena's MK Deception look made it into MK9 as her alternate, so anything is possible.

I'd personally like:

Subzero - MK Deception ice dragon armor (primary)
Reptile - MK Shaolin Monks (his best costume ever)
Scorpion - Injustice costume as a bonus would be great
Baraka - MK Deception primary costume
Shang Tsung - classic MKII look

I know everyone likes Ermac's MK2011 alternate but the one from Deception/Armageddon is his best design ever, hands down.

MK4 Reptile would be nice to see.

If Fujin is in the game I would love to see his MK4 or MKA alt included. Would be nice to see Johnny have his classic look back as well.

Lets see here

Kano- Bald & his MK I Classic attire/MK:DA Alt.
Raiden- His MK I
Quan Chi- His MK4 attire
Scorpion- Was a fan of his MK3 look. Also his Injustice look was badass
SubZero- I would give his "Shredder" attire another shot. With Next Gen it could look a lot better

MKDA Reptile and MKSM reptile.

Injustice Scorpion

1) Scorpion wasn't in MK3. You meant UMK3. Why do people get mixed up with those two?

2) No, just no! Subs MKD alt would be better.

You know i never thought that many people like Reptiles MKDA look. I wasn't a fan of it. but i realized it was that horrible fighting style the "Crab" that just made me not like Reptile or anything about him in that Game

I really wish Raiden's MKDA alt was in this game, but because it isn't, I'll be happy with his MKDA primary and/or his MKD alt.

I also like Fujin's MKA primary.
