Now the chances of this bweing made by an actual company is completely unlikely, however if someone were to try to do this it would be awesome.

Note: This is a combo of different fighting games and genres that I thought might be cool.

Raiden:
Raiden had watched as the Dragon King had torn to shreds his warriors, and his army was on its way to tear into the earth realm. He and fujin came up with an idea for defence. They looked over to see who they could save to possibly save the planet. So they pulled fighters from the present, the past, and the future to save the planet.

Sub Zero:
A survivor of the dragon kings wrath, he had returned to help the Lin Keui fight this new threat. However, he has another reason for wanting to see the Dragon king destroyed, Frost...

Piccolo:
Having sensed a disturbance, he quickly flew to where he believed it to be. He layed low as he watched the Dragon Kings' army enter into the realm. He was prepared to do battle with this new threat.

Scorpion:
Wandering the netherealm aimlessly after being thrown into the soulnado, he found another way out. However, this way out let out into earth, instead of outworld. He was imidieately attacked by members of the Dragon Kings army, who he easily dealt with, however he knew that he would have to fight this new threat.

Ken:
Ken watched as Ryu was destroyed at the hands of the being Shang Tsung, who had sided with the dragon king. He was out for revenge for his old comerade.

Shang Tsung:
Being forced to work for the dragon king, he easily dispatched an earth warrior named Ryu, and also killed the one named Frost. He had figured that working for the Dragon King may have its advantages.

Vegeta:
The Sayain Prince had also felt the energy coming from the Dragon Kings' great army. When he got there, he saw the head of his rival goku, in the Dragon Kings' claws. Full of rage, he set out to annilate the Dragon King and all those who had sworn alliegance to him.

Some more ideas are coming. If anyone has any please submit as I am gonna try to learn some programming to throw something like this together.
