LMAO.
Basically, the entire point of the 3DMK games was that Onaga, the Dragon King, the TRUE King Of Outworld beforw Shao Kahn found his way towards cheating him out of his job, was resurrected and set back in vengeance upon the world with his undead army.
Without Nitara controlling Cyrax, Cyrax retrieving the egg, and Reptile serving as the vessel of Onaga's resurrection during the egg's hatching, there would've been no MK: Deception, and the arc towards MK9 would've never been possible.
