Chapter 5

Global Corruption

"COME ON AANG! GO FASTER! IF THAT HITS THE GROUND, MILLIONS OF PEOPLE WILL BECOME LIKE ME!" Nate yells in terror.

"All most there, all most there..." But they're too late, when the capsule hit the ground, time seemed to stop. In a split second, a massive clud of bright orange and red engulfs the planet.

A few hours later...

A set of four eyes open up for the first time in what seemed like a millenia. He takes a good look at his surroundings and everything seems normal, except, where are the others? He franticly runs into the forest in search of his allies. A few steps later he stumbles upon the group of Nate, Katara, and Aang.

Nate looks up, noticing the being there "Sokka, is that you?" Hearing this, Katara and Aang look up to see the beast infront of them.

"Sokka, the weapon has changed you into the corrupted demon I am."

Sokka indeed has changed into the mutant Nate is.

Sokka stares at his hands and collapses, which morphes him back to human.

An hour later...

"Sokka! Sokka! Wake up!"Katara shakes Sokka lightly

"Owww, Why does my head hurt?"

"I don't know."

"Sokka, you are now a mutant."

"What! No! I can't be a mutant!"

"Sokka, calm down. You, rarely enough, can control yourself while mutated, just like I can."

"Really?"

"Yes, so when you are ready, I will teach you all I know."

A few minutes later...

"It appears you are well enough to begin your training. First off, mutate." At that, sokka mutates, Nate mutates also.

"Alright, first and the easiest atack, the basic melee attack, slash your claws across nate's chest like this." Nate swings his arm in one fluid motion infront of him. Giving Sokka the signal, sokka slashes Nate across the chest leaving a deep claw mark.

"Excellent! Now." Nate holds up his hand and touches his palm. "Touch your palm." Sokka pokes his palms and makes a hole in his skin. "AHH! MY HAND! I MADE A HOLE IN MY HAND!"

Nate chuckles "Hehe... Calm down, that's ok. You see, the skin on the palms of your hands is just a thin membrane. Now inside your arm, there are this creatures called parasite, which are hitched up to your brain. In your mind keep repeating 'launch' and open up your hands."

With that, Sokka concentrates, and his hands spring open, and wormlike parasites flying out his palms. They fly towards Nate, but he catches them.

"Excellent! Now, Last thing to learn is, Launching contagion in different forms and styles. Now, do you see these blister like welts over your arms and hands? Those welts, if popped, will release a contagion that searches out for the nearest living lifeform that it can infect succesfully. But, one can aim it at a paticular object. Aang, Katara, I suggest you step back a bit, or you'll be in trouble"
"Try this." Nate squeezes his hand shut and an orange cloud with these small scorpion like bugs in it releases from his hands. It floats around incredibly fast and then goes towards Sokka. Being mutated though, it has no effect on him.

Sokka trys that and it does the same but It goes to Nate.
"Good, now combine that with a slash."

Sokka releases the contagion while slashing, creating an arc of contagion.

"Excellent. Training is over."
