Sure, but should they even be allowed to do that? I mean outworld is hosting the tournament.. but I'd imagine elder gods at least set a few rules. Anyway I was talking more of just general things that make no sense rather than it being stacked in their favor..
For example.. there are no brackets at all, at some points you are forced to fight people, other times you can volunteer, some people don't even arrive until the very end of the tournament(Ermac). You don't even have to be signed up to fight(Kung Lao).
Scorpion demands Shang Tsung to allow him to fight Sub Zero in the tournament despite a.) Sub Zero being on the same side as him, and b.) Sub Zero already being eliminated from the tournament. Scorpion also fights cyrax and sector despite both of them being on the same side as Scorpion(I assume it's a tournament fight with the way Shang announces it).
Also the lack of killing.. Shang Tsung and Shao Kahn both want people to die after combat, yet no one ever does except Shao Kahn(survives) and the random dude Kitana was fighting. Ermac didn't even kill Johnny, but didn't hesitate to rip Jax's arms off!
The tournament's rules are as follows from what I can glean of the story :
- Unless otherwise stated (MK2 clause), one realm must win 10 consecutive tournaments to merge (they say merge but really it's more like absorbing) the other realm.
- Realms fight until one yields or has no undefeated champions in the tournament.
- Realm protectors/Gods cannot participate unless directly challenged. (MK9)
- To declare a Mortal Kombat tournament, all you need to do is accept the terms of proposal of another realm and be sanctioned by the Elder Gods. (MK9)
Das it mane.
There's reasons for all these inconsistencies, actually, and while I might be wrong, the extrapolation is worth thinking about.
- Shang brings out Ermac because he wants to show his Ermac swag and because he's scared of Liu Kang (which is also why he accepts Kitana's proposal to kill him - same with why he bought out the Lin Kuei).
- Scorpion has his own agenda (it starts with Kill and ends with Sub-Zero) and doesn't give two shits about the realms battling. As to why he's allowed to fight Cyrax/Sektor? No idea (it could be that Shang Tsung cared not about the Lin Kuei and were only there for assistance). The Sub-Zero fight likely doesn't count as he literally dragged him to Hell for the fight (and is eliminated). If Shang gave a fuck he'd call it a no contest.
- Killing isn't necessary for the tournament. Just that Shang Tsung and Shao Kahn literally power up when people die since they'll just suck in the soul. As far as Ermac is concerned, the distraction probably made it so Shao Kahn couldn't order him to finish him, and at this point Ermac is essentially a puppet anyway.
