i like your theory but what if fui jin was trying to help raiden recover his heart (i know very kingdom heartsish if you dnot like it sue me) (we'll ok u better not otherwise its pedigree time lol jk)

that's a nice theory crowkiller!

Im also going to agree

Imagine--Liu Kang vs. Raiden, his former mentor. But he's not strong enough alone. So Johnny Cage and Kung Lao have to help him in a three on one fight to the death! The other heroes, led by Fujin, have to go stop the new threat that Ermac sensed at the end of Deception, while Havik ressurrects Shao Kahn in an attempt to unbalance the peace that the heroes have fought for. Look out for the return of Quan Chi?
I like this idea, personally.

I think Havik's ending is prob. going to be the trigger of the next one with Shao Kahns Return,

My predictions ofr how kombat 7 is going to play out is this. First off the decepton ending. Ermac saves the remaining earth warriors(also known as the deadly alliacne characters) and then sets off to combat a mysterious new threat lurkingin the shadows. havik ressurects shao khan ans soon after kabal destroys havik not knowing that khan was awakened. The newly formed black dragon then pledges their services towards the newly resurected emperor. mileena sits in edenia when kitana and company and bust in and kitana and mileena have one last epic showdown(kill billl style). Khan then begins raising his armies again and with them Sektor who is now programmed with the complete eradication of the Lin kiue. Fujin is summoned to deal with the New Raiden either peacefully or by force the elder gods want him outta the picture. Rain is back to exact his revenge upon Edenia for casting him out. Raiden kills shujinko and proclaims himself sole protector of earthrealm. Liu kang and raiden duel ending in a draw. The earthwarrirs are confused and do not know who to join. Half side with Radien the other side With Liu kang. Fujin has also assembled a force of the few mortals left(night wolf stryker cyrax) in an attemtp to reunify the Earth warriors. So now a four way battle is taking place for Earthrealm while wildcards llike Scorpion and Quan chi wnader like rouges not joining a side trying to put an end to their bitter rivalry. Sub-zero arrives at a newly massacred lin kuie tample and sets off to destroy sektor. Baraka escapes in the battle against bo rai cho's forces and instead recruits Reptile and the two begin to hunt for Rai cho together. Kung lao leads an assault on the brotherhood of shadow and he and Ashrah begin to battle nob saibot and his hordes. Jade and tanya have ended their rivalry tanya winning and thus giving kitna a vendetta after she has dealt with mileena. Sindel is again taken by khan and brainwashed. The dragon king unleashes the final kamidogu and allows this ONE BEING that is in everybody's endings to appear. the elder gods are slaughtered and the fate of many lies in the hands of a few. MOrtal Kombat 7:Devastation.

I think several endings in Dec. are true. Ermacs, Lui's, Sub Zero's and Kenshi (but I think Sub's ending happened before Kenshi's. In one of Kenshi's bios it says that he found Sub Zero badly beaten...)I also think Raiden's and Kobra's ending are correct as well...

if the ending of Havik is true, then the ending of Kabal hasn't happened

Reptile and rain are on the roster to complete the human ninjas.
the REAL dragon king in his REAL is the boss, his normal form not reptiles body, while khan somehow is a boss too. Maybe the real DK will be the big nasty sub boss this game and khan the last boss. (no they dont have to be allies together to be sub boss and boss cause noob smoke had nothing to do with Onaga(reptile form) in MK:D.
Raidens ending is true shuginko(with kung Laos fighting styles) is dead, and kung Lao is in MK7, Not only is edenia and outworld merged again but so is earthrealm and every other realm so Khan can enter earthrealm since its the ONE being and there goes khan kicking ass as NEutral, cause hewants Dragon King dead again they dont like each other.
THe deadly Alliance are back together and they are also neutral since they want Onaga(Dragon king Form) to die as well as khan who is also after them.
Havik will come backwith two new fighting styles and shang tsung and quan chi are back with there badass fighting styles.
sindels ending is true human reptile is back and playable and the REAL onaga is back,
Both if dragon kings ending involve merging all the realms and tanyas ending or jades ending said that, so this is my theory.
Raiden kills shuginko and resurrects Lui Kang, Kang is the Hero and main character once again.
Reptile turns human again Onaga gets his real form back. Shao khan is also resurrected and back.
Shuginko kicks Onagas ass badly but scorpion finishes Onaga off by going through his body and then thAts when raiden later kills shuginko and haviks ending states OTHERS have defeated the DK but left the body laying there, he took the heart from the DK.
Kano is back and kills kira and takes his clan back from kabal and kabal has a score to settle with shao khan who sent an extermination Squade on him in MK3.
Smoke is good again and is helping subzero out with subzeros problems, tanya gets attacked by tarkata and they doubt she survived the encounter but she DID and she has a new beat up form with a rash on her like in her ending and maybe starts possessing tarkata features.
Noob saibot takes ashrahs criss and gets himself outta the netherrealm but he has NOT cleanse himself and is still evil.
Sindel frees kitana from dragon kings control and kitana makes the next game playable.
Rain IS Reiko and one outfit is reiko and his alternate outfit is his rain outfit. Of course that person makes the next game and is working for khan once again OR is GOOD and working against khan so reiko himself can be emperor one day by throwing khan off his thrown.
Sektor is BACK and makes a clan of cyborgs and goes for subzero, Smoke is good again and has his wires working again but sektor trys to make smoke join his cyborg army by trying to tamper with smokes wires again.
This game should go old school with a shokan as Sub boss mainly KINTORO, then the dragon king in his REAL form, followed by shao khan 100% healed not weakened shao khan as the last boss.
jades, raidens,lui Kangs, ermacs, sindels,haviks,ashrahs,kobras,dairous,subzeros,kenshis,shuginkos, ENDINGS are TRUE i cant think of more on the top of my head but barakas or mileenas endings is true i know that they turned on each other in the next game but maybe not as explained in that ending.
Like in MKDA it showed shang tsung and quan chi endings that they turned on each other which was true but they didnt put kano and kangs body together or stuff like that. Mileena and baraka turned on each other but not as said in their endings.
Hope u like my theory, also i think Shao khan sent dairou to kill hotoru or someone HUGE, if its a new fighter then whoever it is this will be explained in the next game.
