We know how his face got all fucked up. When Shao Kahn invaded Earthrealm in MK3, Kabal was one of the guys that the armies attempted to kill. They scarred him up good. FOr God's sake, Kabal needs a respirator to live.
So, maybe at the end? I'm curious to know what Kabal is doing in this game as well.

maybe Kabal is still a member of the Black Dragon in this one and is trying to rescue Kano? maybe during the game he turns good. thats my guess.

yeah i rememebred the thing about hif face being mangeled (if im not mistaken somewere it was said motaro and his Centaurs did it) i just wanna see if it was just and accidental thing (I.E. Him being set on fire or something) or something like motaro personaly mangeling him with his horns or something. either way this should be good.

I think Kabal would be attempting to save Kano. Maybe we will see Kabal get disfigured by Motaro in the ending video of the game?

ya motaro will fuck kabal up!!!!

I could see Kabal trying to rescue Kano, but that seems to predictable. Also, Kano escaped on his own so I could see that only Liu Kang and Kung Lao actually confronted Kabal before his days in Mortal Kombat 3 after he was mangled by Shao Kahn's extermination squads. I would love to see a movie on how Kabal had to wear that respirator to stay alive. I think when we witness Johnny Cage's death we might see Kabal also suffer a similar fate. I think after you beat the Mortal Kombat 2 chapter in this game, we would see a large video of Shao Kahn sending his army through a portal into Earthrealm and watch all the chaos engulf Earthrealm and slowly witness Earthrealm's transformation into a part of Outworld itself.
