It's Onaga.

it's the dragon king im pretty sure in his origaln form

That is not the dragon king! Maybe it was an early rendering of him because it looks more like Shao Kahn IMO.

It looks like two Molochs, a Dragon King/Shao Kahn figure, and Nitara. WTF? Why them?

His ending says:

Once again, the threat to Earthrealm has been vanquished. The Deadly Alliance is no more. What dangers lie in the future, I can no longer foresee. Perhaps the Dragon King will, in fact, return. Perhaps the depths of the Netherealm will spew forth a legion of Oni. Even the Vampire people pose a threat to peace now that Outworld is in chaos. But one thing is certain... Earthrealm must be protected.

All of these are shown. The two Molochs are the Oni. That must be Onaga's original form.

It's the muscled out, amulet stealing, damashi avataring, wing wearing, outworld reppin, green scaling, hahah arcade laughing, kamidogu smashing, emperor of pimpin status ONAGA.

That's who that is.

ooooh. Wouldn't it be neat if Nitara was upgraded to a boss in the next MK? But she would be like an uber Nitara with boss-like moves. A female boss would rock. I don't think she has good special moves right now at all. And her design can be improved but she has a lot of potential with the vampire deal.

its onaga thats obvious. duh whyd u say this after deception lol.

Lmao, couldn't have said it better myself.

wow... i completely forgot bout this ending lol

i think it would be great if Nitara survived Armageddon... and does pose a threat to earthrealm... i think the Vampire race should be focused on a little more... maybe if she survives.. she could be a boss... that would be awesome! i can see her surviving, cause she is the only vampire we know of as of now... and she has great potential

In Raiden's ending although it is clear that on the left is Moloch and his brother look-a-like, at least another Oni, on the right is Nitara however the right center may not be Onaga. It is true that the Dragon King is mentioned, but for them to show what Onaga looked like even if it wasn't how he was going to look like in MKD is a bit lame IMO. Firstly, if that is Onaga in human form, then why did he look all dragon-like in MKD? Oh yea, he merged with Reptile. So then why does he look dragon-like in MKA? Reptile is no longer merged w/ him in MKA....hmmm?

Well my first reaction when seeing Raiden's ending was the the right center guy was the Vampire King. I hope that's who he is. But I guess we'll find out in MKA. Maybe they'll say why Onaga is still dragon-like or maybe his alt will be human like? We'll see. But I don't think it's confirmed that the guy in the right center is Onaga. And I hope it's not, because if he is in fact the Vampire King, then he looks badass.
