Manhattan New York

Manhattan New York

Katara stood on the runway centerline of New York's burning JFK International Airport watching the Boeing 747-8 turn onto the taxiway further down. Her eyes narrowed and she began the long walk to where the China Airlines jet was coming to a stop. And somehow she sensed that someone else besides Aang was going to stop her. The thing was, Katara thought to herself, she was unstoppable. She herself had single-handedly wiped out the Water Tribe, the Earth Kingdom, and most of the Fire Nation. She had killed scores of Americans with just an arc of her hand. And now several hundred NYPD officers were after her. Katara ducked behind a ruined terminal as she saw Aang and Ty Lee exit the aircraft via emergency chute, and look her way. Only they couldn't see her behind the ruined terminal until it was too late.

Ty Lee looked at Aang as they both walked toward the terminal. "

"Something…something isn't right!!" Aang said and stopped, as he looked at the terminal.

"The air's too charged…too tense, like something's about to break loose.

Ty Lee, who wasn't as scared as Aang was, continued to walk toward the terminal. Then, Ty Lee thought she saw SOMETHING move. Before Ty Lee could react to the imminent threat, she was seized by Katara, who by now had become unrecognizable. Well, she was recognizable, but she wasn't the Katara Aang once knew, a caring, loving, motherly girl. Her once blue eyes were now glowing white hot, her once well manicured nails, now as sharp as Azula's, and her hair….even more glossy and beautiful as ever, flowed in the hot air. And she looked angrier than when she killed the man who killed her mother. In the background behind Ty Lee and Katara, the skylines of New York and New Jersey burned.

"Katara, NOOOOOOOO!!" Aang screamed, and she hesitated. Deep down inside, she vaguely remembered the past…feeling it stirring up memories, good times the gang had. Katara finally came to her senses…for a moment. Katara hung her head, struggling to hold back a sob, tears coursing down her face. Aang called back to her. "Katara…you have to stop this. Look at yourself; you're killing people for no cause. You've killed your people, you've killed your brother, and you've even killed Fire Lord Ozai …and Zuko." Somehow, Aang felt he was getting through to her.

Katara dropped to her knees. "Zuko", she whispered. He was the only boy she had loved since he and Katara had been imprisoned in the Crystal caves beneath Ba Sing Se. She growled in a low voice.

"And your point is what, Aang. What did you come here for? You know I can't be stopped. You know I can't be defeated. I am more powerful than any stupid batman or superman combined". A frightened and crying Ty Lee looked on at Aang. Katara continued on. "You see, when I killed the man who murdered my mother, it was unbelievable…You do not know how exhilarating it is to take another human being's life. So I decided to kill another person. And another. In essence, I began to enjoy killing. This thing, this evil took me over. I didn't want to stop, it felt soooo good. It's very arousing. It awakens the beast inside you. Eventually I…I-I…" She began to stammer. Katara looked up at Aang, a wickedly frightening smile spreading across her beautiful face. "And now it's time I take the rest of you with me to the depths of hell!!" Katara hissed, the unbelievable evil completely consuming her again. Aang spoke again.

"Katara, listen to me, you have to stop what you're doing…NOW!! You'll destroy us all-" Before Aang could finish, Katara dropped Ty Lee and literally roared, black energy pouring out of her. Levitating herself several feet into the air, she screamed. "THAT'S WHAT I FUCKING INTEND TO DO, YOU INSOLABLE LITTLE BRAT. DO YOU REALIZE HOW MUCH OF A PAIN YOU'VE BEEN TO ME SINCE I'VE BEEN IN CONTROL OF THIS PLANET??"

Katara had finally pushed herself over the brink, and as Aang grabbed Ty Lee, Katara suddenly unleashed a blast of air equivalent to 100 billion Hiroshima atomic bombs going off at once.

Jin screamed past 30-story mounds of debris and abandoned vehicles, looking in his rearview mirror of his 1980 Chevy C-10 mud truck back at JFK when he saw a sobering sight. A massive shockwave of dust and debris, intermingled with bolts of lightning, hurtled after him at over 12,000 miles per hour. By this time, it was too late. The shockwave overtook the truck, spinning it around several times before taking the truck and crushing it into a metal ball the size of a 1972 Volkswagen Beetle. Jin never had a chance to even stop the crazed girl from destroying his small town city.

Across the U.S. and the world…

In Detroit, two teenage thugs were robbing a corner liquor store. The skies were still sunny and blue here, and a good, toasty ninety-two degrees.

"Come on, man, lets go, give us the money or we'll blow your fucking head off. The frightened Arab man handed over the money. The two thugs ran out. "Yo, man we did it, ha-ha; we did it, Yea man." They hi-fived each other and ran South down Woodward. They didn't even get two blocks when they were thrown flat on their faces. The earth began to shake. "Hey, man, what the fuck?!" one of the thugs said. The shaking grew progressively worse and worse. Law-abiding civilians, crackheads, drug dealers, thugs, gang members, winos, bums, and prostitutes raced into the streets as buildings began to collapse. And the shaking grew progressively worse, along with a growing wind that quick became even more powerful than 22,000 Hurricane Andrews put together. Things began to blow away. Vehicles flew through the air like hot wheel cars. And the shaking reached proportions no one could even imagine. People flew through the air like rag dolls. The streets literally "popped" up and down in waves, whipping everything and anything that wasn't bolted down over a thousand feet into the air and into the advancing shockwave that would eventually devastate most of North America.

People began to run from the miles of coastline beaches as a massive wall of water approached the British coast from the west. Screaming people clogged the streets as traffic came to a standstill. As the water swamped the mainland, people were washed out to sea…then were blasted to pieces as the shockwave crossed the Atlantic, and scoured the rest of the earth clean, killing score of people as it went. However, hundreds of thousands survived due to the quick warnings of CNN, which was cut off in mid broadcast as the shockwave overtook them.

Back In Manhattan…

Within a fraction of a second, Aang had created a ball of air in which to protect Ty Lee and himself from Katara's sudden acquisition of Air Bending. There was no way now that Katara could be stopped. He could hear Katara's maniacal laughter through the roar of air. He had known one day something like this would happen, but he didn't expect it to be Katara. All the wind and noise suddenly stopped, and all the suspended debris fell back to earth as Ty Lee and Aang looked up and surveyed the area.. A small pale form lay in the massive crater carved where Katara had stood. It was Katara, but Aang wasn't taking any chances anymore.

Could this evil have been broken?

Aang slowly proceeded to the spot where Katara lay. Ty Lee stood, rooted to the spot where she had been with Aang. Sure enough, it was Katara...pale, drained of energy. She looked so fragile. In the distance, Aang heard maniacal laughter. Katara's maniacal laughter. Aang was confused. He was holding Katara there in his arms, but he could hear Katara's crazy laughter in the distance...And then he realized what had happened. Katara had become so powerful that this murderous passion infesting inside her had split and escaped. Katara now had en evil twin version of herself on the loose. And the real Katara was dying.
