Nope, it's not Onaga. It's a common Oni/demon from the Netherrealm, like that one attacking planes on Earthrealm on the 1st chapter (source: The Kombat Tether).

Besides, that guy could never be Onaga. He was obviously a demon, and not a dragon. I even thought it could be Shinnok's transformation (MKM:SZ), but it's not.

Well, I think Liu Kang's reveal was enough to know that he won't be any kind of secret boss or anything like that. I know we have no idea of his role, but I think Raiden, mentioning he and Kung Lao as sons figures, will team up with the two again. They are White Lotus, alongside Kung Jin.

Liu Kang should put his head down and be a little less arrogant (he has always been a little, though I love him) and recognize that, we may not know the solution, but Raiden took the best option. For being so irresponsible (ok, I understand the girl he was starting something died, and all of his friends, and etc.) he was left into Quan Chi's hands and probably gave us much trouble to win. He probably said "hey, Lord Raiden, you were right" and everything was cool.

So far, Onaga's participation as I said seems less possible, though the Kamidaggers are carrying the blood of the One Being, but the demon (revealed to be Havik) corrupted its purpose. Shinnok is still the safest option as main antagonist, following theory one.
