Spoilers: (Highlight to reveal)
for one reptile is the dragon king.....beat the game with sindel and it tells how the dragon king took reptiles body and it also explains why in outworld some of the random people will say "have you noticed reptile is changeing" or sumthin around those lines
i also belive that smoke and noob will be sperated for the simple fact that when you beat the game with * i cant remember off hand who it was* but it says that ther was still some good in smoke and he couldnt fight so one will be on the evil and one will be nutreal
also i think they may be killing off subzero and putting him to rest for the simple fact he dies in his own ending along with noobsmokes,and like 2 others.....but i cant say much ther for the simple fact that lui kang is dead and so is raiden which brings back the point in another post about how some people couldnt be super unlockable cuz ther dead........like quin chi and shang shung or mavado......hmm... HELLO i dont think the death thing works anymore concidering lui kang is dead,Raiden is dead,Havik is literally a walking corps my thoughts on who will be unlockable though are kano,jax, and a few others that were listed befor but chances are they wont be but hey what the hell do i know....
ok im done here....
