Let's see I'll have it like this. In MK7, Liu Kang witnesses Raiden kill Shao Kahn, Liu Kang and Raiden fight, in the end Raiden is warped back to his senses, but has to sacrfice himself to prevent the One Being from returning. Liu Kang also learns that Kung Lao succeeded in killing Goro, but died from being mortally wounded. Meanwhile Scorpion finally exacts his revenge on Quan Chi. But the Elder Gods tell him that they require his services one last time, the One Being is still a threat and is preparing to make his return. Meanwhile Shang Tsung survived the ensuing battle and devours Kung Lao's soul. But then right after this happens, the One Being returns by inhabiting Shang Tsung's body. Liu Kang gathers Sonya, Johnny Cage, Kitana and Jax in preparation for the final battle which will bring the realms at peace once more. This is where MK8 comes in. Fujin brings together the Earthrealm Warriors which consists of: Liu Kang, Kitana, Johnny Cage, Sonya, Jax, Scorpion, Sub-Zero, Smoke (newly reformed), Bo' Rai Cho, Ermac, Kenshi, and Cyrax.

Oh yes I forgot about I had planned for Sub-Zero, in MK7. Sub-Zero frees Smoke from his brother's control. Sub-Zero and Noob Saibot battle. It's a long and hard fight, but in the end Sub-Zero comes out on top. Noob Saibot begs that he be spared, but Sub-Zero knows that the brother he knew is gone fully. Sub-Zero removes Noob Saibot's spine. And puts the wraith who was once his brother to rest for good.

Cyrax has some unfinished buisness with Sektor and with the help of Kenshi, destroys his red counterpart and destroys the clan Sektor was setting up saving Japan.

The Earthrealm Warriors march into Outworld where the showdown to end all showdowns is set to begin. Things are not going well, Shang Tsung's power combined with that of the One Being is too much for the Earthrealm Warriors to handle as the One Being prepares to merge all of reality, all seems lost until the spirit of Raiden appears and provides strength to Liu Kang. Liu Kang then prepares his fireball fatality knowing it will not be enough he calls upon the strength of all. Sub-Zero however was gravely wounded in the battle and uses the last of strength. Sub-Zero slowly begins to die. Scorpion holds his former enemy in his arms. Scorpion apoligizes for killing his brother so many years ago and for blaming him for the deaths of his family and clan. Sub-Zero accepts it, thus Scorpion and Sub-Zero make peace as Sub-Zero passes leadership of the Lin Kuei to Smoke before he dies...

Other improtant MK characters appear here: Sindel, Jade, Stryker, Rain, Ashrah, Kai etc. giving their energy for the final attack. Before Liu Kang can unleash the ultimate attack, The One Being creates a shield thus Liu Kang will have to use the attack to break the shield and it will be his only chance but the spirit of Kung Lao is broken free by doing this and grabs hold of Shang Tsung breaking the shield. Kung Lao tells Liu Kang to shoot. Liu Kang unleashes the ultimate attack which destroys both Shang Tsung and the One Being for good. As Kung Lao's soul is set free he approaches Liu Kang and bids him farewell and good luck in life. Liu Kang and Kung Lao bid a tearful goodbye as Kung Lao's soul ascends to the heavens. The Elder Gods then appear and thank all for their efforts, but they have mostly come to talk to Scorpion, Scorpion stands forth., they tell him now that the One Being can never return his services are no longer needed. The Elder Gods then begin to empower Scorpion, Scorpion feels whatever evil that was left in him removed, then the Elder Gods tell him to take off his mask, Scorpion does so and is surprised to see an actual face there. Then as Hanzo (Scorpion's real name) turns away, he finds his wife and son have been resurrected, Hanzo embraces his wife and son finally reunited with his family. At the touching scene, Kitana renews her offer to become Liu Kang's wife. Liu Kang feels torn between his love for Kitana and his duty to protect Earthrealm, but Bo' Rai Cho assures him that he will go to the White Lotus Society to train warriors in case Earthrealm should ever be placed in peril again. Liu Kang smiles as he announces to the shock of the others his relinquishment of his title as Mortal Kombat champion to allow a new generation of warriors to step forward. Liu Kang then accepts Kitana's offer.

Then during the final credits roll, we are in the realm of Edenia witnessing the wedding of Liu Kang and Kitana. Liu Kang looks around many past MK characters are there including Johnny Cage (who's in tears), Jax, Sonya, Ermac and even Scorpion and his family. Liu Kang also sees the spirits of Kung Lao and Raiden looking on. Sindel then happily weds Liu Kang and Kitana to serve as the new King and Queen of Edenia.

The End

Now I know some of you will think that it sucks, but hey I tried. What happened to other characters is left entirely up to you. In fact you can contribute ideas.
