This isn't going to be completed but this is a story mode chapter for Scorpion I had in mind.

Smoke and steam filled the dark hallway. Stone bricks lined the walls and ceiling, while water dripped through the cracks. A lone man in a dark robe walked down the hall, a hood covering his face. He coughed, and his breath was visible in the air, a white mist, indistinguishable from the smoke. A rat scurried along the floor, his toenails clicking on the polished stone.

The man stopped suddenly and cocked his head. A noise was heard, footsteps, coming his way. He lowered his hood and revealed his face for the first time, which was that of a middle-aged man’s. His hair was a dark brown with light blue streaks, which were not really blue, but actual frozen strands of hair. He grimaced, and his lips were also blue, as though he had a constant frostbite.

The air in the hallway began to rise in temperature, and an orange glow appeared around the corner in the hall. Throwing off his cloak, we see that the man is wearing a dark blue ninja outfit, with a gold medallion hanging from his neck. A burst of heat blew his hair back, and, assuming a fighting stance, he waited for his opponent to show himself.

Scorpion stood just outside the tunnel in a small cove. Cracking his knuckles, he grinned and rubbed his palm. Testing, his brows ruffled as he concentrated on his hand. A small tear appeared in his skin and a drop of blood dripped down his wrist. The split widened, and a small, sharp metal blade appeared.
“Show yourself!”
The blade sucked itself back into Scorpion’s hand, and the seam closed, as if it was never there. Scorpion lowed his arm and smiled. He scratched the underside of his mask, then stepped out into the hall.

“Hello, shibito.” said the man in blue. Scorpion smiled at the name, for he was, after all, just a ghost.
“Hello yourself, my friend.”
Scorpion raised one hand, palm upward. It looked as if he was about to extend some sort of peace offering, then---
“Get over here!” he shouted. Thrusting his hand forward, a spear tip attached to a long chain shot out of his palm, flying across the hall and stabbing the blue man in the shoulder. Scorpion yanked his arm backward and pulled the man with it, blood dripping down his shoulder. Suddenly the line snapped, and the chain was sucked back in to Scorpion’s arm like a piece of spaghetti. He growled in rage, and looked up to see that the chain was frozen, and the man had ripped it out of his shoulder with relatively no pain.

The man in blue smiled. He held out one hand, face down, fingers curled. Taking a deep breath, he closed his eyes and concentrated. To Scorpion, it seemed as if all of the moisture was being sucked out of the air. A twirl of mist and water began to form under his hand, then turned to ice. He spread his fingers out wide and the ice ball flew towards his opponent, hitting him in the left leg.

Scorpion screamed in agony as his leg froze instantly, melding itself to the cold stone floor. The man in blue opened his eyes and pulled his hand back towards him, a smile on his face, as if he had just won a small battle. His smile only irritated Scorpion, who removed a dagger from his thigh holster and proceeded to hack away at the ice surrounding his limb.

Fast as lightning, the man in blue threw out his arm to touch Scorpion on the shoulder. Ice instantly formed around his hand, and reached down Scorpion’s arm and torso. Slowly, the blue man knew, he would soon lose feeling in his muscles and be unable to move.
“Say it.” The man spoke in a cool, calm voice. Scorpion struggled, but now only his head was free of frozen entrapment. He sneered. “Never.”
“Say it.” The man said again.
“Fine. You win this round, Sub.”

The man in blue, whose alias was Sub-Zero, removed his hand and the ice began to thaw instantly. Scorpion struggled, and soon the ice shattered, and he collapsed to the ground. Smiling, Sub-Zero held out a hand of support, but Scorpion batted it away.
“You’ve been practicing.” He said, trying to regulate his breathing.
“And you haven’t. Who was your last opponent, a ten year old girl?” Sub-Zero laughed at his own joke, but Scorpion did not find it funny.
“I’ve been busy.” He said.
“As have I.” replied Sub-Zero. “And as such, I assume you are here for the same reason that I am?”
“The awakening?”
“Yes.” Sub-Zero waited as Scorpion pushed himself off of the ground and adjusted his mask. “Come, we don’t have much time.”

Not very far away from the two ninja forms, a man crouched in the shadows. His black outfit blended in perfectly in the dark hall, and if his leaders had been right, he would not have to hide for much longer. Watching the two men battle had been educational for him, and he now knew that this would be no simple attack. He must be careful, but as he followed them down a long flight of steps, he knew that careful was a long way away.

Sub-Zero led his friend down the stairs. Down here it was brighter, torches lined the walls. He knew that time was short, that soon the deadline would pass, and he would have to wait.
“Damn it!” He said, tripping over a rat. He fell down, unable to steady himself. Red spots lined his vision. His head cracked against the stone floor. He blacked out.

“What do you want from me?”
“You killed my family!”
Sub-Zero’s mind was clouded. He was reliving the past.
“To defeat my nemesis...I needed the power of a specter.”
“You killed my family!” Scorpion shouted. He ran at Sub-Zero, fire burning in his eyes. And his face.
His head was a skull, flame engulfing it all over. Jaws wide, his ninja garb was tattered, revealing the skeleton underneath...

“The times have changed.” It was Grandmaster Chi. “We must catch up with the new world order. The Lin Kuei and the ninjas have been at each others throats for too long, and this fusion of man with machine will undoubtedly bring about this peace, which we have so longed desired.”

“Smoke...”
“Shh.., come.” replied Smoke. He raised a metallic arm.
“Are you still in there?” Sub-Zero asked.
“I think so...”

Fire rained down upon his head. Raising his arm, ice spread out from his fingertips and created a shield around his body. Every ember that hit the ice weakened it, and soon it cracked. Covering his eyes, he ran towards his boat. Once he reached it, he jumped into the belly of the small craft.

But there was no craft. He fell through the illusion, down into the water. He tried to come up for breath, but there was no air. Screaming, he fell down, through the sand that was not really there, the black water consuming him, yet he could not feel it. His last vision came up on a wave, and it was of Scorpion. The shibito ran towards a man dressed in green, and then there was a great explosion of light and heat.

And then he woke up.

“Friend. Friend.” said Scorpion, shaking Sub-Zero on the shoulder. “Are you alright?”
He sat up. “I think so.”
“You took a big fall. Come, it is almost time.” Scorpion waited as Sub-Zero pushed himself up.
“You did not damage it, I hope?” Scorpion asked, his eyes as white as the smoke around them. Sub-Zero reached inside his vest pouch and felt around. He sighed in relief and removed his hand.
“No, it is fine.”
“Then we should continue.”

It was hard for the man in hiding to suppress the laugh he felt while watching Sub-Zero fall, but he had. It wasn’t worth enough, not enough to jeopardize his mission. And with the torches it was harder to hide himself. Shinnok would not tolerate his failure.
Shinnok himself was interesting as an employer. He was not powerful, not anymore, but there was an aura around him that suggested he had great strength. He scared Saibot, but he needed the money. And, once he had captured the medallion, Shinnok promised him great wealth.

“This is it.” Sub-Zero said. Scorpion looked around.
“I hear something.”
“I hear nothing. Look, there is the pedestal.” He removed the gold medallion from his pouch, the gold and the jewels glinting in the firelight. He raised it high, above his head, and set it on the steed.

A loud clang rang out in the hall. Scorpion whirled around and threw out his spear, the chain automatically mending itself and forming a new blade. It struck something in the shadows, and Scorpion tugged it toward him. It was a man in a black thief outfit, robes around his head and torso. He grimaced at the pain, but said nothing.
