How one becomes insane
Straight Jacket laid on his back looking at the night sky surrounded by apple cores he had stolen. It was great to eat something besides rice soup. He was famished and malnutrition. He needed his strength before he could repay the world for what was done to him and his sister. He and his sister lived on the streets of the Earth Kingdom when he was ten. Their parents died in a tragic accident leaving them orphaned. They were left on the street where his older sister took care of him. They lived near an apple orchard where his sister was a whiz at cooking and made unique treats. Sadly they were not benders and were looked down upon. One night the two met a man who took them in. He fed them and treated them with kindness that they hadn't felt in a long time. Straight Jacket fell asleep soon after eating and awoke in a room chained up. His sister was chained up on the wall across from him. The old man tricked them and every night he came down to rape his sister. She obediently did whatever she was told and if she resisted a little in any way the old man struck Straight Jacket. For two years they remained locked in the basement until his sister died in front of him of starvation.
After her death the old man decide the brother was of no use and that it was time to kill him. The old man carried a dagger walking over to kill him. Suddenly with every ounce of strength he kicked the old man across the cheek so hard it broke the skin. With the shaking Straight Jacket's chains broke as he fell to the ground. Not wasting any time he took off running and escaping. For hours he ran through the woods until he could run no more. He awoke in afternoon dehydrated and hungry. As he searched for food Straight Jacket saw two earth benders in their late teens abusing their power. An old man was trying to plow the field while the others kept unplowing it with their bending.
"What's with you? I just want to get my crops set up before it's too late." The old man pleaded.
One of the young men spit in man's face and replied, "Why don't you use your bending to help you?" He asked mockingly.
The old man sighed, "You know I can't bend."
"Sucks to be you." The other young man said.
Straight Jacket turned to see a tiller and took hold of it. Quietly he walked over to the benders who were still teasing the old man. With a quick motion the front of the tiller stuck out of the second man's chest. Both the companion and the old man stared the victim in shock as well as the young man who killed him. Straight Jacket pulled the tiller out and looked at next the other teen.
"That was my brother!" the young man shouted enraged. Slamming his foot on the ground a huge boulder appeared before being punched toward the murderer. Straight Jacket moved with amazing speed burying the tool in the benders head.
Straight Jacket looked at her prey and said in the same tone, "Sucks to be you." Pulling out the tool he tossed to the old man and walked down the road. The young warrior traveled to through many towns leaving a trail of dead benders. He started believing all benders abused their power for their own gain. The two who he felt were the worst were the Fire Lord who sucked life out everything to further his gain for control over the world, and the Avatar, the most powerful bender who was no doubt arrogant with his power.
As the fire nation invaded a village he was passing through Straight Jacket saw two soldiers raping a villager for their own pleasure. By morning the whole platoon was brutally murdered except one. The one who escaped told another platoon. It took the fire nation a year to capture the murderer with brutal consequences. Several fire blasts were shot to bring him down. The burns were minimal and scaring was weak. After a three years in the asylum The Fire lord came to see Straight Jacket offering his freedom for the Avatar's head. Straight Jacket in reply stood up charging slamming head first breaking his guest's nose. Three guards jumped him throwing him into the cell locking him in. The Fire Lord spit the blood from his mouth and demanded that his mind to be broken and that he be controlled.
Now he was free to walk the world doing as he pleased. Straight Jacket turned his head left and saw something that caught his attention. "It can't be." He whispered at the site before him unable to comprehend how it was possible.
