Few little facts I wanted to let everyone know of.

Other realms may participate since Onaga's actions affected all realms and put them all into danger. Also this makes it so for once there is no given villian...and can be more character specific as far as arcade mode goes. Such as if Kitana is in it and chosen, she could go face to face with Quan Chi or Shao Kahn in the end. Get my drift?

cool idea. but i think they'd pick fujin

Yeah if I had a say in the characters....I'd use

1 Sonya (She could find out about the new black dragon clan via Kobra and they could team up)

2 Liu (Earth Realms "Chosen One")

3 Darrius (He still needs to spread more chaos)

4 Stryker (He said in Konquest he wanted to be a Seidan Guard, he could be against Darrius)

5 Goro (The whole Shokan vs Centaur thing)

6 Kahn (He definately wants to rule Earth Realm)

7 Havik (He would be the perfect bad guy with good intentions)

8 Scorp (He's the Elder Gods' Chosen Fighter)

9 Sub Zero (He still needs to expand on the new lin kuei)

10 Reiko (He wants power)

11 Dairou (He could easily be sent to kill any of the potential earth realm guardians)

12 Tanya (She a power hungry b*tch)

13 Raiden (If he lost his job he would try to retain it above quitting anyday)

14 Fujin (He's the people choice to take over)

15 Quan Chi (Shang Tsung was proven to be dead, so it's possible Quan coulkd be alive enough to try)

16 Noob (He seems to be the perfect representative of neather realm right now)

17 Sektor (In konquest he was damaged which explains why he wasnt involved in the last couple games so theres no reason why we can't be in this one)

18 Kobra (He could use information of the new black dragon to get revenge for Kira taking his spot)

19 Kira (she needs to find two more black dragon potentials)

20 Motaro (The whole Shokan vs Centaur thing)

21 Ashrah (She could also be a good potential candidate for guardian of earthrealm since shes been trying so hard to be pure)

22 Baraka (He's clearly still alive)

23 Kabal (He's the leader of the black dragon)

Those are my choices...Others woud be

-Cyrax
-Mavado
-Jade
-Cage
-Kung Lao
