Have they figured out what Quan Chi is yet? Is Quan Chi a native to the Netherrealm, an Oni? Or was Quan Chi human once?
Quan Chi has always been an Oni, dweller of the Netherrealm, according to canon.
I always have the impression that he LOOKED different, maybe like a common Oni (Moloch, other Oni's on MK and MK:SM) but was intelligent enough to develop his physical appearance and be stronger. That's just an impression I always had about him.
Anyway, Quan Chi was the guy who helped Shinnok kick Lucifer's ass. If we consider Taven, VERY OLD, knew Shinnok as an Elder God and at the same time he knew Shao Kahn as Emperor of Outworld, it means, after Onaga (who is pretty damn ultra VERY VERY OLDER), and all of that was before the God Wars, Quan Chi is also very old.
That's enough time to become one of the most powerful sorcerers of all.
And if we start asking in uroboros way, like "so, where did the Oni came from?", we must remember Lucifer was lord of hell, maybe he had some way to do it (really don't wanna imagine).
I keep hearing Lucifer being canon in MK. When was this? I find it kind of odd.
I believe in MKD's Konquest mode, somewhere it says Quan Chi started off as an Oni. Then eventually formed in to the being he is now. The backstories seem to shift sometimes so I don't know much of that is true.
I've never heard that and I've played both the Deception konquest mode, as well as the Armageddon one. Maybe it was somewhere in Deception? Could you help?
Also, it depends a lot on who says it. Most residents of the Netherrealm said things, but they have absolutely no clue about the truth. NRS could give Quan Chi ANY possible backstory without contradicting anything. Some dialogue in Deception's konquest mode was just for fun, like Shao Kahn saying "Go tell Reiko that I know he's wearing my helmet behind my back!" )
As for Lucifer....... I don't know where that backstory of Shinnok started, but in no bio or ending of Shinnok in any game, is Lucifer mentioned.
Edit: Looking online, I found that he is mentioned in a ?guide book? for MK Mythologies in which they spell Raiden as Rayden and also said Sub-Zero was born in America, the oldest of three children, which included a brother and sister.
Hardly canon, unless Frost is actually his long lost sis'
"Quan Chi? Yes, I knew Quan Chi before he became a sorcerer. He was not much different from me then."
