UPDATE: Cleaning up my Author's Notes. Story remains the same.
Shao Khan longs to invade Earthrealm. But what hinders him from conquering it are the Warriors recruited by Raiden, God of Thunder and protector of Earthrealm, and the accursed Mortal Kombat. So Shao Khan thought of ways how to enter Earthrealm without violating the law of the gods and Mortal Kombat.
He found an answer in the form of a disruption in time and space, resulting in the creation of portals that randomly appear and disappear; portals that connect to other realms. How and why the disturbance happened matters not to Shao Khan. To him, it's a great advantage. Any random warrior from another realm that came to Edenia, Shao Khan kills or enslaves immediately. And with the gods trying to fix this anomaly, Shao Khan can create a portal connecting to Earthrealm.
Yet his plan on conquering Earthrealm will be delayed. From other portals connecting to Outworld and Edenia, armies march out to invade. Some were easy to defeat, others prove a challenge. And more still come. The bloodbath is a good opportunity for Shao Khan to strengthen one of his trusted minions, his creation composed of the blood of fallen warriors: Skarlet.
Released from her imprisonment, Skarlet is let loose to kill the invaders. But through fighting an army by herself proves to be good and bad for her. Good for every kill she did, her skin absorbs the blood, healing her wounds and making her stronger. Bad for every damage she takes, she looses blood and weakens. And when she comes out victorious, any blood that has not yet absorbed by the ground, she takes it to regain her health and strength that were lost.
An incident happened to Skarlet. When she lost lots of blood by fighting an army, a portal suddenly appears behind her, sucking her inside before it closes. Skarlet travelled through the whirling dimension within the portal before she was spit out. A weak Skarlet found herself in a wooded area, very different from where she came from. Wherever the portal sent her, Skarlet knew she's in another place. She needs to find another portal to go back to her master.
But for now, she needs blood...
