I think everyone will betray everyone!
the DA will join the DK. So will the onis, red dragon and black dragon (if there is any left). At the same time, Khan and his men struke back! The DA betray each other and the DK, the red Dr. has it's own agenda, the Black drag. tries to survive. Earth fighters have to stop chaos.

i think it goes like this... (i know ive been saying this too much) the earth warriors (maybe with the DA) would try to kill reptile thinking that he was the dragon king and they were finally able to beat him. when reptile is on the ground as is begging for mercy (or gets killed), the real dragon king will appear and taunt the earth warriors, leading to another MK game.

possible people at the top of my head to be the DK:

1.) Liu Kang
2.) Bro of Liu Kang
3.) One of the people of Reptile

a few people think that Reptile will attract attention while the real D.K. will live. Good.
- wut if Kung Lao didn't kill Tsung?
- what if Shang killz someone after being morphed into Kang? like Cage or Sonya/Jax

or Maybe That Shao Kahn has the ability to make Body Doubles like Quan Chi does in Baraka's Ending.
