Nexus 13.0

First Day on Nexus Plus Eight Hundred. FD+800. (PRESENT)

Central Metropolis.

Two people stood inside a small house looking out of the same window at the side street before them. The occasional hovercar drove past the front lawn of the house they were gathered inside, while some men and women wearing suits and professional-looking dresses walked down the sidewalks holding briefcases or bags in their hands.

The rustling behind the two figures looking out the window was quieting down, as all the equipment was brought upstairs and shoved into bags. One of the two at the window, a teenage girl with black hair down to her shoulders, turned around and saw her comrades standing behind her, looking her way with readied expressions on their faces. "Is it time?" Mikasa Ackerman asked, stepping away from the window and towards Armin and Levi, both of whom were wearing black suits. She was in a black skirt herself that allowed for good movement, and a white button down shirt with a black jacket on as well.

The blond teenage boy behind her nodded his head. Armin Arlert cleared his throat a little and turned to face the dozen people behind him. "For everyone who decided to come, thank you."

A tall woman in front of Armin who had only one eye and a purple ponytail nodded her head at him. The mutant cyclops named Leela lifted up the duffle bag on the table next to her and put the strap over her shoulder. In the bag specially made to block out x-ray sensors, were her group's weapons: her smuggled ray gun, two sharpened metal spikes for Mikasa, a knife for Fry, a bat for Armin, and Bart's steel-lined yoyos, it was not a very stocked arsenal.

"Where is Smoker?" Levi asked. The short black haired man looked around to see if anyone had an idea as to where he could be. He frowned seeing no response, and continued darkly, "All we can hope for is he's deciding to use his military privilege to help us in some way."

"Or he could have already betrayed us," Bart suggested grimly.

The two other twelve year old boys next to Bart looked in at him with confused looks. The yellow skinned kid noticed their strange looks and lost his depressed look, "Not that it would matter. We're going to kick butt anyway man," he bragged, though the nervous look on his face was impossible to hide.

Stan looked past Bart to his friend who was already dressed in his Mysterion costume. For a kid their age to dress like that was not as strange as if it were an adult, so they were hoping the masked child would be looked over by their enemies. Apparently Kenny still had not told the others in the room who he was, and only Stan knew of his close friend's secret identity. "You ready?" Mysterion asked in a low voice.

Stan, or Darth Marsh, nodded his head back at his old friend. He turned to his Master, and stated, "We should get moving towards our objective. It is much farther away than the city's control tower."

"You are right," Anakin told his pupil, then looked over to the short but serious man with short black hair. "Lead the way," he told Levi, and Levi nodded back over at him.

"Ackerman, Arlert," Levi spoke, not turning to Mikasa or Armin as he did so. "Get those nullifiers off. I will free Jaeger," with that he grabbed the knob and opened up the door, stepping outside in his black suit. The short man reached into his pocket and lifted a pair of sunglasses up to his face, putting them on before walking away with a taller man and a young boy walking behind him. Anakin and Stan were wearing their usual gi's, but underneath loose-fitting brown dress shirts and pants to make themselves fit in a little more. Also, the extra layer of clothing helped hide their lightsabers from view which were strapped to the belts of their gi's.

The door closed behind the three of them and the rest of the group stayed silent for a few moments. The old man standing behind them at the base of the stairs suddenly spoke up, "Good luck to all of you." They turned around to Carl Fredrickson, and the old man cracked a smile at them. "Give 'em Hell."

A teenage boy with messy brown hair standing in the shadows stepped forward. He was wearing a black jacket that went far down below his waist all the way to his ankles. He also had a long red scarf wrapped around his neck that extended midway down his back and the front side to his waist. They would have scolded him for dressing so weird, if this was not the same way he dressed to all of their previous rebellion meetings.

"Surprised you're still here," Bart joked up to the older teen. Just like most every other time he'd been spoken to before, he just ignored the person and stared ahead with a purpose.

"Well, we're glad to have you," the other person who was still standing at the window said back towards the teen. Everyone looked over at the kid with spiky white hair, Killua, who smiled around at them all. "I'm surprised so many people have followed my foolish mission, but I'm grateful you're all here to help. Now," Killua walked over to the door, the boy wearing a black suit and lifting up a pair of sunglasses of his own that he put on. His black collar was popped up to keep the power nullifier beneath hidden, but it was still a little visible to the others behind him. The kid looked over his shoulder with a smirk, looking right back at the old man whose house they were in as he said, "Let's go give 'em Hell."


Metropolis South Gatehouse

"Hey Ray," a man standing in the small guard building on the southern edge of Awul's capital city looked over to the coffee pot on the edge of the room. Standing in front of it was his comrade and his shift mate Ray, a guy with short blond hair wearing a black suit like his comrade. The guy making some coffee looked humphed tiredly to show he heard his friend, and Cyril continued, "Have you, been getting any weird vibes this morning? A few people I passed on my way here this morning looked pretty nervous."

"What? That's silly," the flamboyant-sounding man replied as he put a mug underneath the coffee machine and it started filling up with steaming hot liquid.

"I don't know," Cyril mumbled, turning himself fully to look over at Ray. "Even the guards who had the night shift looked nervously energetic, and those guys are almost always ready to pass out when we get here."

"Hmm," Ray hummed. "I'm sure that it's nothing," he continued, while turning his head to look over his shoulder at his guard mate. "Anyway, have you heard that Tony and Karl are, are..."

Cyril was staring at Ray for a few seconds, when he noticed the coffee had filled up his mug to the top and poured over. Cyril started sweating nervously, the fat man wearing glasses seeing Ray's gaze aimed over his shoulder, towards the window that looked out over the fields south of the city and the southern road from Metropolis. "Umm," the fat man started up, seeing his friend's hand getting covered in steaming hot coffee, but Ray did not even respond to the heat. "Thought you said it was nothing," Cyril joked, but Ray just kept gawking and looking over his shoulder. His mouth slowly lowered more and more while his eyes grew larger.

Ray lifted up his arm slowly, his whole body shaking. "C-C-Cyril," Ray stuttered, moving his arm covered in hot coffee. He lifted it up as it shook horribly and he pointed behind his comrade out the window behind him. The other two guards on duty with them who were supposed to be watching the inside of the city started shouting loudly as apparently they had seen it too.

The larger man turned slowly, not wanting to even try imagining what could be behind him. Cyril was only halfway turned when he was able to see the enormous, hundred foot tall, fifty foot wide, door made of darkness out the corner of his eye. He finished turning around and stared at the massive black door-shape sticking out of the grassy field on the south of the city. "What is that thing?!" Cyril exclaimed, lifting up his right arm and pointing out the window.

"M-Maybe it's not what it looks like," Ray offered. He jinxed it. As soon as he stopped speaking, the door started acting like a door should, letting things in. Out of the portal of darkness almost a hundred figures walked or flew onto the field.

Right in the center of the large group, was a twelve foot tall silver robot. It looked very powerful, but what intimidated the four men staring at it so much, were the two letters engraved on its chest.

"'T- T,'" Ray whispered, the blond haired man with a furry mustache taking a step backwards and falling to the floor. He whispered in fear, "You don't think that's, Timmy Turner? Do you?" His black haired friend stayed quiet, his hands shaking uncontrollably. "Tell me Cyril, is that him?!" Ray shouted at his friend wearing glasses who managed to stay on his feet.

Cyril nodded his head, and in a shaky voice whispered, "It's him." He pulled both hands up to the sides of his head and collapsed to the ground, shaking his head over and over as he tried to imagine this was just a dream.

"Cyril! Cyril!" Ray ran over and shook his guard mate by the shoulders as the heavyset man tried to cower himself into a tiny ball.

"You guys see that?" Another guard shouted as he ran inside the main room with his partner. Karl and Tony were both blond guys with strong German accents. Karl's blonde hair was much longer, Tony had glasses on, and they were both more muscular than the other two guards who were already inside.

Cyril looked up at the two Germans who just ran in. "Do we see it? Yes we see it! It's a fucking hundred foot tall black doorway in the middle of the road out of the city!"

"Karl, the far-range identifiers," Tony demanded. The German man wearing glasses walked over to the window and peered out while Karl ran over to the cabinet and grabbed out some electronics.

"Which one?" The long haired man questioned.

Tony looked back and pointed at the object he needed. Karl walked over with it and his shorter haired comrade grabbed it from his hand. Tony peered through the device out the window. Numbers and letters raced across the screen of the object as he watched the small army approach the city from a half a mile away. "Shit," was the first word out of his mouth.


Southern Outskirts of Metropolis

"You know, it would have been a lot easier if we were transported inside the city," Nightwing said to the silver haired boy on his right.

The older teen didn't respond to Nightwing's complaint, but his spiky haired friend did. Sora smiled back at the leader of the Teen Titans unlike Riku, "Looks like there's some sort of forcefield around the city. Couldn't just spring up a portal of this size in there, sorry."

"It's alright," Gohan assured them both from where he was hovering forward slowly above their heads. The fourteen year old wore a purple fighting gi with a red belt tight around his waist and a white cape on his back to imitate his late Master, Mr. Piccolo. He continued with a smirk, "I like this more, the intimidation will work in our favor."

Vegeta grunted in amusement on Gohan's right side, "Yes, they will be so afraid of this army of children. Not that you could even call this batch of weaklings an army," he frowned menacingly at the people who shot him dirty looks and most of them looked away fast. A few like that kid in the straw hat, and the one with pink hair who he'd known longer, kept glaring at him a little longer than the rest. He respected that.


SOMEWHERE INSIDE METROPOLIS

"We have just received word that a large force has assembled on the outskirts of the city," a man called behind him into a room full of people. The dark room beneath Metropolis was full of creepy figures, and one of them walked towards the man in the doorway.

"What are you talking about?" The purple lizard creature questioned the man.

"Two of our spies in the perimeter witnessed the group come out of a portal just outside the city. Tony reported that among others, Timmy Turner is in the group."

"And the Saiyans?" The purple alien with a long tail asked, his eyes widening as he took another forceful step towards this person. Cooler glared at him through the dark room, and the man gulped before answering.

"They're here too-"

Cooler's tail flicked in front of his body and suddenly the man in front of him no longer had a head. "Saiyans," Cooler growled. "I knew it, they came!"

"Do not fret my friend," a calm voice called from behind him. Everyone in the room looked over at the tall, bald muscular figure walking towards Cooler. "This works with my plan. As promised, you will not fight the Saiyans. Tetsuo and the Saiyans can take each other out. Imagine the damage to the city they'll cause."

Others in the room grinned as they understood what the bald man was getting at. The bald guy continued as he smirked widely, "After the city is in ruins, we'll be there to pick up the pieces. Tetsuo, Goku, Turner, none will be able to stand up to us any longer." He clenched a large fist in front of his face and even Cooler started grinning at the sound of that.

"Alright then," Luthor stated, "let the games begin."


METROPOLIS HIGH SCHOOL

While walking towards the high school, an orange haired teen stopped in his tracks. He turned completely around and stared off into the distance. It's coming isn't it?

Another boy walked up towards him and pushed his glasses up the bridge of his nose. The teen with straight black hair looked at his classmate with spiky orange hair and asked, "You feel it too, Kurosaki?"

"I've felt it coming for days," Ichigo replied to Ishida as he turned his head back around. He thought back on something he heard the night before and stared at the school in front of him. "Wonder if this place will still be here come tomorrow?" He and Ishida stared off with dark looks, expecting something terrible to happen.

"Ichigo! Ishida!" The two of them looked to their left where a girl with long orange hair down to her waist was running towards them. Two other girls walked behind her at a slower pace, each of them looking more on edge than the bubbly teen in front of them.

"Sup Inoue?" Ichigo greeted the girl.

She smiled at him and the other boy next to him. "Let's have a great day okay?" She asked them, smiling wide at her friends.

Both high school boys sweatdropped as she seemed to be the only one who didn't feel the tension in the air. "Uh, yeah sure," Ichigo mumbled, scratching his head. He looked over his shoulder one more time then started walking forward towards his school. Hopefully not for the last time, he added to himself.


SOUTH ENTRANCE OF METROPOLIS

The four guards at the gate house were panicking as the large group that appeared before them was getting increasingly close to their entrance point. "Should we open the barrier?" Ray asked the others, looking terrified as he did.

"We can't do that," Cyril told his gay guardmate. No matter how scared he was, this was their job.

The two German blond men looked over at Cyril angrily. Karl walked towards him with a furious expression. "So what? You vant us to help you hold them here?" His strong German accent emerged as he lifted up the leader of the guard post by the collar. "Vhy don't you have a look through these?" The man with long blond hair slammed the device into Cyril's chest.

The fat man with short black hair grabbed the device nervously. He turned back to the window where he could see the group that appeared getting even closer. They were about to hit the barrier around the city that was normally invisible if you didn't spend most of your time looking at it. Cyril looked through his glasses and through the special binoculars and pointed them straight at a muscular man floating forwards in the air. He had spiky blond hair and a lightning bolt scar over his right eye. "Laxus Dreyar," the man whispered, "threat level Dragon."

"Dragon?!" The other three around him exclaimed. Karl walked back to his comrade and snatched the binoculars back, "What do you expect us to do against that?"

"They're coming through the barrier," Tony shouted. The blond man wearing glasses pointed at the large semi-translucent dome that surrounded the city. A few of the figures in the front of the army put their hands against it, confused as to why it was stopping their entry.

"It won't stop them," Cyril whispered. The chubby man ran his hands through his black messy hair. "When are those reinforcements getting here?"

"Not soon enough," Ray whispered as a boy with spiky brown hair walked between some of the others. He lifted up his right hand and a weapon appeared in a flash of golden light. The kid leapt up in the air and then slammed the weapon with a key on the end of it into the barrier.

Sora's Keyblade sliced right through the wall and then he turned it sideways. The large slightly yellow forcefield shimmered, then from the line Sora cut in it, it split to either side creating a large opening for all the fighters to get through. "Piece of cake," the teen exclaimed as his weapon/key disappeared from his grasp again.

"Well that didn't take long," Cyril muttered, hating when he was right.

Riku walked through the hole in the barrier Sora cut for all of them, and the boy with spiky brown hair dropped down next to his older friend. Sora landed on his right, then turned in with a wide boastful smile. "Don't try showing off too much before we're even inside," Riku muttered, though he looked around at the large opening in the barrier a little impressed by Sora's work.

"Hehe," a girl on Sora's other side giggled, leaning forward and looking in at the two boys on her left. Kairi smiled at them, "Let's have fun, okay?"

"Sure," Sora responded. "But we also have to take down the Underworld while we're here."

Riku chuckled at the other two's carefree attitude, then looked back at the city himself. Ansem's voice suddenly spoke in his mind, "You and I both know what awaits us in this city. Tetsuo and his armies will be ready for us." Yeah, he will be, but we can handle it. I'm glad you let us know all about the alliance before we came into this. "Yes, well I was not looking forward to you getting caught off guard when the NEG attacks us inside. They will support their Underworld allies." Haha, Riku chuckled mentally. "What is so funny?" You said 'they,' which means you no longer consider yourself a part of the NEG. Riku didn't get a response which only made him smirk wider, glad Ansem was going to be on their side for this one and not fighting for their enemies. Well, for what it's worth, thank you. From what you told me, we're going to need your help for this one.

Without replying to Riku, Ansem just thought to himself, My help? Why should I help you boy? The man looked through Riku's eyes out at the city. You should be able to handle most of the people in this city. As long, as you don't run into them.
