So I was browsing through concept art for previous MK games and noticed there's quite a few things that wound up on the cutting room floor that seemed like character concepts worth exploring, and many things introduced in lore that have never been further explored. Wanted to make a thread so people can get a look at would-be MK characters that may actually give clues as to what sort of folks might be introduced in MKX.

Tiamat

A burly reptilian humanoid that was conceptual during Deadly Alliance. I wanted to bring Tiamat up first because his concept seems to have some hints towards being in MKX. As some of you may recall from this thread, supposedly a reptilian character is being developed for the game that may or may not be Reptile himself. If Reptile is not in the game, or perhaps is back to his human guise, it may be possible that Tiamat or a similar likeness will be represented in some form.

Baphomet

Another Deadly Alliance junker that is a goat-headed demon. There is currently no character like Baphomet in MK and with Drahmin being thrown onto the "do not reuse" pile (along with possibly Moloch), another Oni representation may take their place.

Hachiman

Hachiman is another Deadly Alliance reject that has not had his assets reused elsewhere. He is a kendo practitioner but little was developed beyond his appearance.

Zebron

By now most people know about Zebron. He was originally sketched out as a joke, but he was apparently considered to be implemented as a joke character at one point briefly.

Original Blaze

The original concept for Blaze gave us a fire-man who was a lot more... detailed than the original version from Deadly Alliance and wields dual hatchets.

Original Kintaro

The original concept for Kintaro was as a karate tiger-man. While Kintaro is indeed a tiger-themed Shokan, a tiger humanoid is a different beast (literally) altogether.

Tengu ninja

The Tengu clan of ninja and its leader, Wu Lae, were introduced during the Konquest mode of Armageddon. By all accounts they should still exist in the MK universe in the rebooted timeline, but it remains to be seen if they'll ever be referenced again

Unnamed Sorceress

A female combatant that uses tassels as weapons. In the second concept piece with various other drawings, her hair is spiked up and she has long, sharp fingers.

The undead general

A scrapped armored warrior concept from Deception. This is likely a concept that has already been cannibalized for its assets to be used on other characters.

Evil Sumo

The evil sumo concept is interesting because despite it being such an early concept, it has never been reused in any form for any subsequent game in the series. There is still no sumo wrestler or super heavyweight human in MK.

Unnamed male vampire

This unnamed male counterpart to Nitara got as far as having an untextured model completed of him before ultimately being scrapped. Nitara also had a concept with much smaller wings that would probably be less cumbersome if she were to be reintroduced.

Belokk

Will never appear in MK. Eurocom's creation that is forever in rights limbo.

Ruutuu

Ruutuu is an evil spirit that is portrayed as an all-black figure during the Challenge Tower in MK9. Absolutely nothing is known about this character besides that he has been haunting Nightwolf's tribe for a long time.

Oh, one more thing I found.

There is this Aztec warrior that was a concept during Deadly Alliance. Given that we have been introduced to Kotal Khan, NRS is at least looking at old concepts to reuse for new characters.
