Kai
Sektor
Cyrax
Sonya Blade
Kenshi
Sub Zero
Scorpion
Jax
Kano
Johnny Cage
Kung Lao
Rain
Katinna
Rayden
The Fire God from MK:M
Mileena
Noob Saibot
Reiko
Baraka
Mavado
Nitara
Chameleon
Vorpax from MK:Konquest (Hidden)
Blaze
A New Oni (Hidden)
Nightwolf
Smoke
a female Black Dragon member (Hidden)
Shang Tsung(Old)
Quan Chi

Sub Boss: Maybe a Centar with four arms
Boss: The Dragon King

before the Sub Boss you would have to fight both Shang Tsung and Quan Chi at the same time.
Konquest will be back and so will The Weapons and so will impale.
I also would love to see the return of the Aggression metter from MT: Trilogy and Brutalitys.
I would love for there to be a kreate your own Kombatant and online playing and have Imortals famous song tahtw as in MK the movie be played in the game and have the endings be in 3D.
heres everyones ending in my mind

Sonya's: She quit's the special forces and marrys Kenshi
Kenshi: same but he finds a way to close the portal to Out World and Earth is finley safe from any inviders.
Kitana: she in her throne room and Liu Kangs ghost appears before her and he tell her not to worry about him he is with his brother Chang and is in peace and tells her to just wed Rain.
Rain: same as Kitanas ending but he comes in after Kitana sees Liu Kangs ghost.
Jax: Takes Sonyas Place as leader of The Special Forces.
Kung Lao: he is back home and he and Kai train new members for The Temple of The order of Light.
Kai: same as Kung Laos
Rayden: destroys Shinnkos Ammulet and gos back to beening an Elder God and has someone new to beening the protecher of Earth.
Quan Chi: Sits on the throne of Outworld and has The Gurads bring in Shang Tsung and Shang trys to kill him but Noob Sabit protech Quan Chi and Quan Chi kills Shang and laughs.
Shang Tsung: He Kills Kung Lao and Takes his soul.
Nightworlf: Tells his people of his many battles agianst Evil and The Dragon King.
Smoke: He joins Sub Zeros Lin Kuei.

Johnny Cage: He wins a Grammy for best Martial Artest of the year.
Chameleon: kills himself before Kung Lao finds him.
Mavado: Kills Jax and Cyrax at the same time and walks away laughing.
Nitara: Kills Princess Kitana and drains her of her life.
Scorpion: Finds Quan Chi and kills him and is turned into his old human form and Rayden comes to him and tells him for the good he hes done for Earth Realm he will be able to see his wife and child in the heavens. Scorpions revenge is over
Sub Zero: Sub Zero Welcomes Smoke into his clan but is attacked by Sektor but Sub Zero Kills Sektor by frezzing him and kicks him into a miliion pieces.
Sektor: Sektor walks in and kills all the new Lui Kuei and becomes the new Grand Master
Baraka: Baraka Confronts Rayden but he is killed by Rayden himself.
Milenna: Milenna angered of her defeated by Kitana goes to find a new place to dewell.
Noob Saibot: He has The Earth realm now but still one thing remains and that is Reiko.
Reiko: Reiko battles Noob Saibot for controol of Earth Realm and Reiko wins.
Cyrax: Cyrax has a endless battle with Sektor over a Lava pit and both fo them are killed.
The Stages are sp real you can break though walls pick up things and ineract with the stage kinda of like Power Stone but better.
