HELLOO, everybody! It's time to head for, you guessed it, Avatar World! After a few cutscenes, of course. :P


Chapter 58: The Negatar's Opposite

The Death Egg

Dr. Eggman solemnly stood at his control terminal and studied the action that had just occurred at Bowser's Castle on his tiny monitor. Bowser's fortified fortress crumbled and burned in the volcano. Eggman's five robotic henchmen stepped in. "Hello, Doctor." Orbot greeted. "Might I ask what's wrong?"

Eggman let out a sigh. "Bowser's been destroyed."

"Bowser? Somehow, I do not think so." Decoe replied.

"Those idiot plumbers and those snot-nosed brats made a fool out of him. They tore old Bowser apart like a worthless piece of tissue paper. We've always felt that special bond, seeing as we're both constantly humiliated by someone we can't stand. I will not stand for this. We've got almost all of the Emeralds, but we still need that last Sol Emerald. Not to mention the Chaos Emerald Shadow has. Hrn, what to do, what to do…"

"I might have a suggestion, Doctor."

"Oh?" Eggman turned and noticed his emotionless counterpart in the doorway. "Why, hello, Nega! What brings you here?"

"Actually, Doctor, I have come across a rather extraordinary discovery."

"A discovery?"

"I seem to have determined the location of the Master Emerald."

"YOU HAVE?!"

"Correct, Doctor. Ever since you mentioned the Master Emerald was stolen from your cargo vessels, I have been searching for it. I assumed the Kids Next Door would have something to do with it. Lord Gnaa was generous enough to input his Darkness in several of our robots, turning them into Heartless. I have sent those Heartless about, and they have detected an incredible energy source coming from beneath the Kids Next Door's Museum in Washington."

"Hm, for a worldwide army of nose-picking kids, they hold some interesting secrets. You must admit how fascinating this world is, Nega."

"Fascinating indeed, Eggman. Now perhaps you should go see what our dear friend Sonic is up to. I will gladly lead some Heartless down below and retrieve that Emerald."

"Very well, Nega. I'm counting on you." With that, Dr. Eggman walked out of the control room, followed by the henchmen.

"Sir, I've actually been reading about these Heartless." Decoe said. "I'm not entirely sure if we can trust them."

"As long as Negatar Gnaa has control over them, we'll be just fine."

"But Eggman, it's said that eventually, the Heartless-"

"Enough! The only one I want to hear negativity from is Eggman Nega. You can just be silent. Unless you'd rather end up as a Heartless yourself."

Decoe gulped. "Y-Yes, Doctor."

"I DON'T LIKE WHERE THIS IS GOING IN THE FUTURE. YEEHAW!" Cubot screamed.

"Ugh. We've got to get that voice fixed." Eggman sighed.

Abandoned auto-repair shop

The heroes came out of the portal and appeared before the abandoned shop, where Team Psychic, The Quads, Eva, Kade, and Dimentia were already waiting, along with the members of the Order of the White Lotus. "Guys!" Mika exclaimed. "You made it!"

"Thanks to Shaunie." Nigel smiled. "What are we doing here?"

"This abandoned repair shop serves as our secret meeting location in this world." Piandao replied.

"'This' world?" Nigel asked. "And who? The Order of the White Lotus?"

"Correct." Jeong-Jeong said. "Come inside, all of you. Our leader awaits."

After following them into the old shop, King Bumi stomped the ground, opening a secret tunnel on the floor. Jeong-Jeong held a flame in his hand to light the way while Mewtwo lit the tunnel with a psychic glow. They eventually reached a huge, deep underground chamber that was lit with green crystals and had a large, circular table with the symbol of a lotus in the center. Across the table sat a man, who appeared chubby, dressed in a dark-blue robe with white outlines, a short grey beard on his face, and grey hair tied in a bun as he calmly drank a cup of tea. (Play the "Sealed Temple" Theme from Skyward Sword.)

Each of the old men and the Grim Reaper took seats around the table as the chubby man paused drinking his tea, giving a smile. "A pleasure to meet you at last, Kids Next Door. Guardians of this world. Would you like a cup of Jasmine Tea?"

"Ooh! I'll have some!" Kuki cheered.

"Umm… who are you?" Nigel asked.

"My name is Iroh. Grand Master of the Order of the White Lotus. Leader of this ancient organization."

"The Order of the White Lotus is a secret organization, who have long-since worked for the spirits, keeping order and balance across the many worlds of our cosmos." Pakku continued.

"Our homebase lies within the vast Avatar Realms." Piandao said. "It is where we hail. But there are many of us across the universe, keeping watch and protection of the worlds."

"We were informed of the invasion when a fellow Lotus, Wesley Dodds, sent us a call from the Brotherhood Base." Mewtwo explained.

"However, he was informed himself… from The Brain's very own apprentice. We have him to thank for that." Clockwork reminded.

"It was even Wesley Dodds who called us all to this world." Jeong-Jeong continued. "He received nightmares of the great apocalypse… as did we all."

"So, wait, Clockwork… you work for the White Lotus?" Jagar asked.

"You too, Grim?" Nigel asked.

"Mewtwo?" Mika questioned.

"I am the Underworld's protector." Grim told them. "Clockwork and I have served the White Lotus for generations. So explains why Bumi was able to live for so long."

"And why I never lose my spirits! Eh heh heh heh!" Bumi cackled.

"Each of us members have kept our job secret." Mewtwo said. "The Darkness targets whoever's the strongest in the Light."

"After we arrived in this world, we knew the Dark Master would be returning." Iroh spoke once more. "And we knew that Destiny would call for the heroes to take the great journey before them. So, I sent my fellow Lotuses out to test you in battle."

"That explains why you all ambushed us…" Eva deduced.

"Yes. We had to be sure the powers that would mark your place in legend were awakened." Pakku replied.

"But now, the Dark Master has truly returned. Already the Darkness is descending." Iroh said, closing his eyes. "I can sense it all. Two of Gnaa's own accomplices have already fallen before it."

"Yeah, Bowser." Rachel said.

"Gaul, too." Morgan replied.

"And I predict the rest will soon follow." Iroh spoke. "Such time will be the unveiling of others' destinies. The poor child at the Brotherhood is a great example. But as the Heartless have returned, so have the mystical Keyblades. When the time comes, the Keyblades will find their chosen holders, and let their powers be theirs."

"Like Shaunie…" Fanny remembered.

"But what about the Dark Master?" Eva spoke up. "You called us here because you had a way to defeat him. So, what is it?"

"Patience, Child. The Negatar is a powerful incarnation. His existence has been ever since the beginning of bending. When the all-powerful God of the Universe, Arceus, blessed the very first mortal with the powers of the Light Elements. In turn, his Negative was cursed with the Dark Elements. And when each one died, they were both reborn with the same spirit."

"You mean… the Negatar has a Positive counterpart? And he's alive?" Rachel asked.

"Of course, Child. No Negative can exist without their counterpart. The Negatar is merely the mirror image of someone who is pure of heart. His name… is Avatar Aang. The most recent incarnation of the Avatar, bender of all Four Light Elements. He is the one who can match the Negatar's power and vanquish the Darkness with his Light."

"Well, that's great!" Rachel smiled. "So, all we do is find this Aang guy and get him to kick Lord Gnaa's butt!"

"Wait!" Morgan spoke up. "I'm still not sure that we should do that… I still think there's good in him."

"What?" Nigel looked confused.

"She… had a little chat with Gnaa." Buddy told him. "She tried to turn him to good, but it didn't go well."

"I'm still not giving up. Maybe if we find this Aang guy… he can help us."

"Morgan…" Iroh spoke again, "I admire the light in your heart. But the Negatar's heart has been consumed in Darkness. It is how he lured the Heartless back to life. There is no hope for him…"

"Hmm…" Morgan looked away, biting her lip.

"Where does Aang live again?" Nigel asked.

"In our homeworld. The Avatar Realms." Iroh answered. "And we've brought the perfect vessel for traveling there. Behold…" A garage door opened on the side of the room, directing everyone's attention to a massive chamber where an orange rocket rested, with a few yellow lines around the wings.

"Whoa. What is it?" Lee asked.

"The Gummi Ship. Specially designed for traveling great distances."

"But we must be on guard." Jeong-Jeong spoke once more. "Though creatures of darkness, spawned from the evil within peoples' hearts, the Heartless are intelligent lifeforms. They've developed their own means of space travel, and have likely took land on other worlds."

"'Guess we have others besides the Russians to worry about, huh, Eva?" Kade joked, nudging Eva as she gave a sigh.

"I can't go." Jagar spoke up.

"Why not?" Misty asked.

"I have to stay here and help Yuki. Who knows what those witches could be doing with him now?"

"I bet Clockwork knows." Olive said, shooting the spirit a glare.

"But you won't tell us, will you?" Jagar asked him.

Clockwork only sat in silence, tipping his hood over his eyes. "It's a danger to speak of the future."

"Then tell me what good you are." Jagar said angrily, walking away.

"Jagar!" Misty yelled. The two spirits spared one last glance to the Time Ghost before following him.

"Let him go, Clockwork." Iroh told him. "He knows his destiny. He must follow his heart."

"In that case, we should stay behind, too." Kami said. "We need to look for the Kongs and track down K. Rool."

"We're going with you." Mika replied. "K. Rool took Mew, and we have to find him."

"You've been with the Kongs, haven't you?" Lucario asked Kami. "I've detected traces of their auras on you. I can use that to track them."

"Well, she WAS crushed under Donkey after we came out of hyperspace. HAHA!" Kweeb laughed.

"I feel like we should stay behind, too." Sonic said. "In case Eggman shows up around here, we'll need to stop him."

"Well, 'ave fun with that, ya little boomers and sheilas. I'm goin' to Avatar Land!" Marine exclaimed.

"…Yeah, someone should go and look after her." Tails suggested.

"I guess I'll go." Sonic offered. "I can count on you to look after things, right, Tails?"

"Leave it to me!" Tails fist-pumped.

"Perfect! Less weight to slow us down." Iroh said. "Especially with Bumi onboard."

"I can't help but get myself fat from too many feasts. Heh heh." Bumi snickered.

"Call us if anything crazy happens." Sonic said to Tails.

"You got it."

"Master Iroh! The ship's fixed and ready for takeoff." Numbuh Infinity called from the ship's cockpit.

"Then let us set sail." Iroh said.

From outside, a massive hatch opened several yards away from the auto shop as a platform rose and lifted the Gummi Ship up. The space craft tilted upward as the engines charged before finally shooting to the sky. Watching them from below, Shadow the Hedgehog glared. "I think I may have discovered Gnaa's weak spot, after all." (End song.)

Final Brain

Madame Rouge leaned against the walls of one of the base's outside walkways, inhaling smoke from a cigarette and blowing it as Nolan and Team Brotherhood approached her. "Madame Rouge, we need to talk."

The slim woman released a puff of smoke and said smugly, "Vhat?"

"When you ran over those GUN Troopers back at Chicago, I noticed that bus looked very similar to the one that killed Dillon."

"It vas a metro bus, Boy, zey all look alike."

"Then how do you explain the dried blood Nolan saw?" Danika asked.

"It vas obviously the result of an unfortunate accident. Some unlucky soul must have gotten run over."

"Yeah, somebody like Dillon." Nolan said angrily.

"You forget, Boy, zat happened in Quahog, I found zat bus in Chicago. It vas a big coincidence, no? And besides, if I recall, it vas a different bus driver who caused the accident, not me."

"How do you know who did it?"

"Firstly, everyone knows about the accident with Dillon. But such a thing could not happen if some random person vas not driving the bus. I cannot say I know any zing about zem, only that he clearly did not finish driving school if he vas responsible."

"I don't believe you! I think you're hiding something!"

Madame Rouge looked behind the three children and smirked. "Perhaps you vould like to say somezing, Brain."

"Indeed." The disembodied brain spoke, rolling over. "It is clear you are reliving past remorse for your late friend. Such feelings are good to have, Nolan, but let your anger and rage be focused on the Kids Next Door. It was their fault for having 'decommissioned' him in the first place."

"He's got a point, Nolan." Danika said. "You have been getting a lot of nightmares, lately. It's probably making you paranoid."

Nolan looked away. "Yeah… maybe."

"Hey, I know what we need!" April perked up. "Why don't we get the Toxic Four and head to the beach?"

"A most brilliant suggestion." Brain agreed. "A squadron of my villains were about to head to Azula's world, and she knows of the perfect place. Why don't you all go with her?"

"Yeah!" Danika smiled, grabbing Nolan's chair and turning him around. "Come on, Nolan, a little mini-vacation is just what we needed. I remember when Numbuh 1 took one, and that did him wonders." She rolled him off as April followed and left the two villains.

Madame Rouge let out another smoke puff as Brain spoke. "He is catching on to you, Rouge. Why did you choose to keep that bus?"

"For memories." The Madame released another puff. "I do not fear what your miserable apprentice could do to me. I'd be more afraid if I vere ze one who issued the order." She smirked and held the cigarette over Brain, tapping a few dust specks onto his dome before walking away.

Brain sat there and calmly brushed the specks off with his psychic. "Perhaps I should attend this mini-vacation, too…"

River cavern, outside of Chicago

Scarlet Vargas finally awoke, finding herself lying beside a small river inside a damp, rocky cavern. "Hoo, you're finally awake." She heard a relieved voice say. She sat up and faced Violet, sitting on a rock near the cavern's entrance. "I got you some milk."

Scarlet glanced to her left, seeing a small dish of pure-white milk. "Where are we?"

"I found this cave just outside of town. You were knocked out when the creature attacked you, so I thought I'd bring you here to rest. I got the milk from Kroger's. It got wrecked during the invasion, and everyone fled, but the milk was okay, though."

"Peh. I bet you think this makes us friends, doesn't it?"

"I would hope it does."

"I'm still going to kill you, you know." Scarlet said, standing up and extracting her claws.

"…Alright, then." Violet replied, standing up and walking over, tilting her head up so Scarlet got a better view of her neck. "Go ahead. Just slice it right here where it hurts."

Scarlet gritted her teeth and quickly rose her claws, but paused right when she was about to cut. "What's the catch?"

"No catch. It's plainly obvious you won't be satisfied until I'm dead. And as your loving cousin, it wouldn't be right to hold you back."

"…Huh. You want me to do it, don't you? Bruce finally lost interest in you and went after that Luna chick."

"Uh, no. Last I heard, Bruce was captured, and… I haven't really seen him since. Anyway, the reason I'm letting you have this chance is because I know you won't have the heart to do it."

"Oh, so that's it? You think I'm scared, don't you? Too afraid to end the life of a fellow relative?"

"I don't think you're afraid at all, Scarlet." Violet said, tilting her head back down. "I actually think you're quite the opposite. Your heart is telling you this is wrong, and you're strong enough not to kill me."

"Please, I would've wiped your head clean off your body by now. It's just… well, I've been hanging out with Lehcar a lot."

"Whatchu mean?"

"I mean that this is too easy. If you're really deserving to be in the Kids Next Door, you would give me a better chase."

"Why would that matter to you? You just wanna kill me and get it over with, right?"

"Sure… but if I'm going to descend into darkness, I wanna have fun with it. In fact, maybe I could make you suffer first."

"Scarleeet!" They looked outside the cave, seeing Lehcar skidding over to them on her rocket shoes. She stopped once inside and caught her breath. "Scarlet! I've been looking for you ever since you didn't show up after the invasion… oh, it's you." She noticed Violet.

"She thought she could make me buddy-buddy with her after she saved me." Scarlet said smugly. "She was way off."

"Aren't you going to kill her?"

"She wants me to 'suffer' first." Violet remarked.

"Sounds reasonable to me." Lehcar shrugged. "But if you aren't going to, let's go. That fool Bowser let his prisoners escape, so we'll have to get after Rachel again."

"He did, did he?" Scar smirked, turning back at Violet. "Then that means Bruce is free, too. Let's make this a game, Vi… Try and find him before I do!" She stretched her claws before running off, Lehcar joining.

"Hmph." Violet shook her head in disbelief. "You just like making excuses…"

Nicklodia Galaxy

The Gummi Ship zipped out of hyperspace and was sailing toward the atmosphere of a strange world. "There it is." Iroh spoke. "Behold the Realms of the Avatar."

"The polar ice caps at the top and bottom are the Northern and Southern Water Tribes, where waterbenders are born." Pakku said.

"The land to the west is the Fire Nation, the most technical-advanced nation where firebenders dwell." Piandao pointed.

"That big chunk of land right there is the Earth Kingdom, the biggest and strongest. I suppose you can guess which benders are found there. Ha ha ha ha!" Bumi cackled.

"And to the north, south, east, and west sides lie four temples where the peaceful Air Nomads once roamed."

"But due to a fierce Hundred-Year War by the Fire Nation, most of the Air Nomads have been exterminated." Jeong-Jeong explained. "The only ones that remained were Avatar Aang and his bison companion."

"Don't forget Momo!" Bumi mentioned.

"And it was thanks to Avatar Aang's efforts that our world was saved."

"Uh-oh!" Iroh exclaimed as enemy ships were suddenly bombarding them. "The Heartless are in this world, too! A fleet of them is coming."

"Everyone hold on!" Jeong-Jeong ordered. "This trip has taken a bumpy detour!"

"It's the sea all over again…" Wallabee moaned.

"The ship is malfunctioning!" Iroh exclaimed as the ship was passing into the atmosphere. "Brace for impact! We are about to crash!"

In a grassy meadow on the world below, a man dressed in green garb and grey hair was humming a merry tune as he rolled a wagon full of cabbages.

"Watch out for that Cabbage Merchant!" Hoagie exclaimed.

"HEY! GET OUT OF THE WAY!" Numbuh 4 screamed.

The Cabbage Merchant noticed the incoming vessel, screaming and flailing his arms and legs as he looked left and right, back-and-forth.

A few miles away

Just moments ago, miles away from where the ship would crash, in a field that was between two enormous and distant walls, a group of children was playing. First was Katara, a choco-skinned girl in a blue dress, black shoes, and black hair tied in a ponytail and two loops around her ears. Next, there was her brother, Sokka, who wore a similar blue get-up, had a sash around his waist with a white boomerang, a sheathed sword which he wore on his back, and had black hair that was shaved around his ears, and also tied in some sort of ponytail.

"Ahem."

Sorry. A "warrior's wolftail."

"Huh? What is it, Sokka?" a blind girl asked.

"Uh, nothing. Let's keep going, Toph."

The blind girl, Toph Beifong, was the youngest of the group. She wore green shorts and a green T-shirt, with a whitish-yellow sleeveless shirt and skirt over them. She wore a large belt around her waist, a green-and-yellow headband over her black hair, and was barefoot. Currently, the girl and Sokka stood with their faces just inches away from each other, locked in a starring contest. Toph kept her cocky smirk while Sokka gritted his teeth, struggling to keep his eyes open.

The contest went on for a few minutes, and Sokka's eyelids were getting weaker. Despite all his efforts, they snapped shut in a blink. "Ha ha, you blinked!" Toph laughed.

"What? You can't even see!"

"My feet can sense any motion, and can see what the human eyes can't. As long as it isn't airborne. Including when humans blink."

"Grrr! I want a rematch!"

"You're on!"

"Hm, sometimes I feel like you two are crushing on each other." Sokka's girlfriend, Suki remarked. She dressed in green garb with black padding down her front. Her face was decorated with a sort of white make-up, and she bore two fans tied around a sash.

"Nah. She's too young for me." Sokka said.

"Besides, he could never match the awesomeness that is Toph. …Haha, you blinked!"

"D'oh."

"Some things never change, do they?" Zuko asked, former Prince of the Fire Nation and current Firelord. He dressed in red and yellow robing, black boots with slightly curled toe-ends, messy black hair, dual swords sheathed on his back, and had a scar along his left eye.

"Hey, has anyone seen Aang?" Katara asked.

"I think he's playing with the polar-leopards outside the Outer Wall." Sokka replied.

"Hehe. You know he once told me he wants his next incarnation to have a fox-hound as his/her pet?" Katara smiled.

"Well, since the next Avatar has to be born in the Water Tribe, that shouldn't be so hard." Zuko joked.

His, Katara's, and Suki's faces frowned in shock when they were caught in the shade of a massive vessel, passing straight over them and heading outside the Outer Wall. When it vanished behind the wall, a huge cloud of smoke could be seen in the distance as the earth shook tremendously from the crash. Feeling this quake the strongest with her Seismic Sense, Toph blinked in shock. "HAHA! YOU BLINKED!" Sokka shouted.

"Come on!" Toph yelled, grabbing Sokka by the shirt collar and dragging him off. "Let's go see what that thing is!" The other three exchanged quick glances and followed after them.

At the crash site

"MY CABBAGES! !" the Cabbage Merchant screamed as the smoking Gummi Ship crushed his entire wagon. "YOU IDIOTS! How am I supposed to start a worldwide Cabbage Corp. when people keep destroying my cabbages?!"

"Ehh, put a cork in it." Wallabee retorted.

"So, these are the Avatar Realms." Eva observed.

"Gotta admit, nice place for running around." Sonic said.

"But new worlds means new adventah!" Marine exclaimed. "Where is this Aang kid anyhow?"

"Somebody help!" an old man screamed, dashing over and directing back behind him at smoke rising from a building. "There are strange creatures attacking the train station!"

"Heartless!" Iroh already knew. "They have found their way here after all. White Lotus, let's get after them."

"But what about finding Aang?" Rachel asked.

"We have arrived near Ba Sing Se. Avatar Aang and his friends usually hang around here. Search around for him. You have seen the Negatar, so you should know what he looks like. Good luck." With that, the eight White Lotus men dashed off to where the Heartless were attacking.

Rachel looked to her right to see a massive stone wall miles ahead. "I guess that's the place." She figured as they started their walk.

"I wonder, if this guy's supposed to be the Negatar's opposite, just what kind of person is he?" Hoagie asked.

"I'd assume that, since the Negatar's heart is filled with Darkness, the Avatar must be pure of heart, or something." Nigel guessed.

"Just remember, not every Negative is totally opposite to their Positive." Rachel said. "Back at Chicago, Lord Gnaa was unstoppable. I doubt this Avatar will let himself be known to a bunch of out-worlders so easily."

"WOOHOOOO!" They jumped away when a large animal, which looked to be the mixture of a leopard and a polar bear, dashed and came to a sudden halt, causing the kid who was riding it at the time to shoot straight off, landing face-first in the ground. That's when a massive white bison, with six legs, a flat tail, and an arrow along its back landed beside the kid. "Haha! I beat you again, Appa! Whoa!" The bison tackled the child and started to lick his face with a huge tongue as the child started laughing.

The operatives crouched behind trees and rocks and watched this, gaping at the sight of the child. He had the same articles of clothing the Negatar had, except the black parts were orange, and that same baldhead with an arrow. The children walked out as Rachel was first to speak. "Umm… excuse me?"

The boy stopped laughing as the two faced the strangers, Appa stepping off the child as he jumped to his feet. "Oh, hi there! I haven't seen you around before. There's something… different about you kids."

"Long story." Nigel replied. "But, are you… Avatar Aang?"

"Hmm. Let's find out." With that, the boy grabbed some water from a nearby river and threw it out using waterbending, afterwards stomping the ground and flinging rocks out, unleashed flames from his hands into the air, and finally blew a gust of wind straight at the kids' faces. "All four elements… yep. I'm the Avatar."

Their expressions grew into wide smiles. "That's great!" Rachel exclaimed. "Listen, we need your help. There's-" Her sentence was cut short when a bunch of Chaos Spears suddenly rained down and exploded between them.

The rest of the Gaang was on their way, seeing the explosions around their friend, along with the bunch of strangers. "Aang!" Sokka yelled.

"What? SHADOW?" Sonic shouted when the black hedgehog appeared out of thin air.

"So, you're the Negatar's opposite." The hedgehog spoke. "Which means… if you're destroyed, the Negatar will no longer exist. YAH!" Aang quickly dodged when Shadow threw more Chaos Spears, running as fast as he could as the ultimate lifeform gave chase.

"Shadow, WAIT!" Sonic yelled.

"Hold on, ya crazy drongo!" Marine yelled as they both ran after him.

"Come on, let's-" Nigel was about to say before a blast of fire got in their path.

"Who are you guys?!" Zuko asked angrily.

"Who do you think you are coming into our world and attacking our friend?" Toph yelled.

"Wait, you don't understand!" Nigel yelled in defense. "We were just-"

"The only thing I understand is creampuffs… and whenever a bunch of aliens come down from the sky and start attacking, we attack back!" Sokka said, aiming his sword.

"Whoever you kids are, you're gonna think twice about attacking the Avatar when we're done." Suki said, readying her fans.

"Heh. Bring it on, Sister." Fanny remarked.

"We just got done with a war, we aren't letting another one happen." Katara said fiercely, bending and raising some water from her pouch.

"You already started one with loops like those." Eva retorted, raising her own water.

"You don't stand a chance against us." Zuko said, readying his flames.

"Then I guess there's no way around it." Nigel replied, alighting his own hands with flames.

"Alright, then. Let's do this." Rachel said, drawing her sword and facing Sokka.

"We'll kick your butt!" Toph exclaimed, getting in a fighting stance.

"We'll kick it harder!" Angie exclaimed, getting in a similar stance.

"Team Avatar: attack!" Sokka announced. "Flying Kickapow! AYAAHH!" (Play the "Battlefield" Theme from Smash Bros. Brawl!)

Boss fight: Avatar Gaang

Both teams went after their individual opponents and started to battle. Nigel began dodging left and right to avoid Zuko's fireballs, jumping and kicking his own flames to push the prince back. Angie swiftly dodged her head to the side as Toph kicked short rocks her way, afterwards stomping bigger boulders out of the ground, making Angie yelp and dash away before Toph crushed her. As she ran around, she kicked more rocks at Toph, but the older earthbender just punched and shattered them with her fists.

Sokka and Rachel rapidly swung their swords at each other, with Rachel easily able to duck Sokka's horizontal slices being at a shorter height. When Rachel swung at his legs, Sokka easily leapt over and tried striking from the back, but Rachel held his sword back with hers as Sokka leapt back, hurriedly running as Rachel chased him around and sliced at rocks, flinging the rocks at her as she swatted them away. Eva and Katara went to go battle on a river, with Eva raising Water Whips to shoot at her, only for Katara to raise a water barrier and block, sending the wave at Eva, who rolled to the side and sent her own wave.

Fanny hurled green fireballs as Suki shielded with her fans, dancing her way over to slap her fans across Fanny's face, but she breakdanced and sent spiraling flames from her feet to knock Suki over. "Hah! Don't you know fans only make flames stronger?" she smirked.

"Believe me, I know." Suki replied, jumping up to kick Fanny several feet away, into a tree.

As Fanny recovered and saw Suki running at her, Abby and Kuki suddenly got in her way. "Don't worry, Fan. We got yo' back." Abby assured.

Suki only lowered her fans for a sec and made a whistle, summoning two more girls in the same wear as her: Mai, who had raven-black hair and wielded daggers, and Ty Lee, a cheerful girl with brown hair in a long ponytail.

"Aw, man. Not more." Abby whined.

"I can't believe you got me to wear this cheesy outfit." Mai said to Ty Lee.

"Come on, Mai, you'll love it." Ty Lee smiled. "Now let's just go and kick these girls' butts." Ty Lee stylishly flipped along the ground over to Kuki, who happily spun-jumped overhead and skipped away while Ty Lee chased her. Mai drew her daggers and shot them at Abby, who looked slightly startled and dodged them, letting them stick perfectly to a tree. She turned back in fright, seeing Mai run after her, and hurried away.

As Fanny stood up and went back to throw flames at Suki, Patton watched them and hurried over to help. "Hold on, Fanny. I'm coming-" But he was stopped when a squad of even MORE girls in the same outfit dropped down and surrounded him, blowing their fans against their faces as Patton gave a cocky grin. "O-ho-kay, ladies, good old Pat Daddy's gonna take it easy on ya. One at a time." Right away, one girl kicked him in the crotch, the second smacked the back of his head, the third kicked the side of his head, the fourth punched him in the gut, while the fifth kicked his behind. "Er, okay, take it slower now. AHH!" Patton screamed when all of the girls piled up and started beating on him. "Fanny! Help me!"

With Nigel and Zuko, the Firelord conjured Fire Daggers in his hands and started to swing them at Nigel, who ducked most of them, but was cut across the right cheek. Nigel created his own Fire Daggers and swung back, clashing against his before he was able to slice Zuko across the chest. The Fire Prince jumped away and lit himself on fire, surrounding the Brit in a huge ring of fire. Nigel looked around for him before Zuko jumped through the flames behind him. He dodged to the side as Zuko tried to Flame Punch him, afterwards jumping back out of the ring to try and punch Nigel from behind again.

Rachel and Sokka kept throwing swings at the other as Rachel stabbed at Sokka, but the teen jumped onto her sword and leapt straight up. "Flying Kickapow!" he yelled, coming down with rapid kicks that Rachel back-flipped. She swung at Sokka once more, but he held her sword back and jumped several feet away, taking out his boomerang and throwing it while Rachel took out hers and threw it. The two boomerangs came in contact and knocked against the other as they spun before they flew back and hit their own masters in the head.

The two shook the dizziness off as Sokka made a whistle. The sound of a hawk's cry could be heard as a red hawk landed on Sokka's shoulder. Sokka held a finger up, gesturing for Rachel to wait a moment, allowing him to take out some paper and a brush with ink. He wrote Claw at blonde girl on the paper before rolling it up and sticking it in a compartment on the hawk's back. "Get her, Hawky!" The hawk, Hawky, made a cry and did as told, flying over to begin clawing its talons at Rachel's face.

Angie and Toph continued to kick rocks at each other before the blind earthbender burrowed beneath the ground. Angie closed her eyes and felt around the earth using Seismic Sense, seeing Toph coming below her and stomping, sending a quake directly at the blind girl. Toph growled as she came back up, rolling along the ground to make some rock armor appear over her body. As Angie approached, Toph sent more rocks at her, but she dodged and jumped onto Toph's armor, beginning to punch and make dents in it. Toph grabbed and threw Angie off, using her bending to easily slide up a steep hill where she popped perfectly round boulders out of the ground and sent them her way. Angie yelped and quickly dodged the fast-coming boulders, but the last one that was coming to her, she was able to kick her foot at and hold it back, afterwards pushing it straight up and bowl over Toph.

Katara surrounded herself inside a water bubble and made eight watery tentacles appear around her, trying to swipe at Eva as she tried to get close. Eva drew out her Phantom Sword and sliced the tentacles, afterwards slicing through Katara's barrier, forcing the Water Tribe girl to back away and make ice shards stick up from the water below her. Eva jumped and was able to stand on the very tips of the shards. Katara conjured a wave and surfed towards Eva, washing over the Ocean Princess before stopping and turning back, attempting to wash over her again. Eva rolled away and conjured her Water Fists, and Katara's eyes widened when she saw the fists before Eva bashed and sent her flying away.

Fanny, Abby, and Kuki were still locked in their fight with Suki, Mai, and Ty Lee. Kuki flipped over the circus girl and bounced off her face, but Ty Lee angrily grabbed the Japanese's leg and swung her around before smashing her against the ground. "You are not prettier than we are."

Abby kept trying to dodge Mai's daggers, grabbing some of the projectiles off the ground and sending them back, but they were only blocked off by other daggers Mai sent. "Man, how many of those things do you have?"

"As many as Mushi has those crayons." Kuki replied.

"What's wrong, kiddie getting weak?" Mai smirked, running over to swing daggers at Abby, who barely ducked as part of her ponytail was cut off.

"Man, you sound just like that Danika chick. And just as annoying."

Fanny was having an easier time blocking Suki's fan swipe with her kicks, eventually able to kick the weapons away. Fanny then noticed Rachel on the ground, having her face torn apart by Sokka's hawk. She shot green fireballs at the bird and made him retreat to Sokka's shoulder. Fanny ran over to help Rachel up as Suki went beside Sokka. Rachel held up her shield as Fanny grabbed onto it, lighting on fire as Rachel spun and hurled her at the two, causing them great damage from the impact of the flaming shield and girl. Sokka growled in anger as they both stood up, grabbing each others' arms and doing double-flipping over to the KND officers, stopping so that Sokka could spin and swing Suki around to kick them away.

Angie made her way up the slope, dodging Toph's incoming rocks until she was finally close enough. Toph's eyes widened in shock when she sensed Angie grabbing a boulder with a green energy chain, swinging the Boulder-n-Chain around and bashing her, greatly damaging her armor before it shattered. The rock bashed her again and sent her rolling down the slope.

Zuko jumped through the flame wall again, this time having his dual swords raised as Nigel quickly dodged Zuko's rapid swings. Nigel looked frightfully as he was dodging closer toward the fire wall, and when he was barely touching it, Zuko stabbed his swords, catching Nigel between them as the swords went through the flames. Nigel just rolled under the right sword and got away as Zuko pulled the now-flaming swords out, Nigel dodging faster to avoid being cut and burned. Zuko also sent flaming airwaves toward the Brit, but Nigel was eventually able to run up, take the blades, and knock Zuko around with them before jumping up and stabbing down, sticking Zuko to the ground by his shirt. Zuko pulled the blades out and jumped out of the ring, using his powers to make the ring close-in on Nigel. The Demon Prince kicked on his rocket shoes and shot out of there, flying straight up and spinning around, catching himself on fire like a meteorite as he came at Zuko and forced him to the ground with incredible force.

Nigel landed beside Angie as Toph and Zuko recovered and saw the other beat up. "Zuko!"

"Right!" Zuko nodded as Toph shot rocks from beneath them that flung them straight up atop the slope again. Toph made stone soldier statues come out of the ground as Zuko lit them on fire, sending the flaming statues after the kids as they performed spin attacks. Angie stomped the ground and made statues of KND soldiers come out as Nigel set them on fire and sent them to attack the enemy soldiers. Nigel and Angie exchanged a glance and smacked the others' hand as they switched sides, going after the other's opponent.

Nigel ran toward Toph as the blind bender kicked more rocks, but Nigel jumped high up and kicked fireballs that Toph backed away from. When Nigel landed only inches away, Toph hurled more rocks, but Nigel ducked and performed a breakdance, sending spiraling flames out. "AHH!" Toph screamed when the flames knocked her off her feet. "You burned my feet!" Nigel only stood up and smirked.

Angie was easily able to jab Zuko's face with rocks from the ground before the 7-year-old shot one up from below and sent the prince flying down the hill. "I got 'im ruffled up for ya." Angie said to Nigel.

"Yours, too." he replied as they smacked hands and switched back.

Katara used her water tentacles to hold back Eva's fists until she was able to freeze the Ocean Princess's legs and make her fall over, giving a smirk. Eva smirked back and made her own watery tentacle come up from behind Katara, grabbing the Water Tribe girl's ponytail and spinning around the air, tossing her away afterwards as Eva unfroze her own legs.

"Ohhh… huh?" Patton awoke after the merciless beating by the girls, finding them all smiling as they still surrounded him. "AHH!" He suddenly noticed he was dressed like one of them, growling angrily as they all giggled. "Why you… oh?" He immediately ripped the clothing off, blushing greatly when he seemed to be wearing no clothes underneath except his underwear. "Wait a second, you girls undressed me?! …That is just plain creepy."

Rachel rapidly swung her sword, trying to get Hawky away, and was finally able to strike the bird and make it retreat. "AHHH!" she heard Sokka scream from behind. "SNEAK ATTACK!" Rachel instantly dodged behind the charging boy and struck him back, kicking his butt and pushing him on the ground. "Grrr! SLAPPA-DAPPA-DOO! !" Sokka exclaimed, rapidly swinging his sword aimlessly as he made his way over to Rachel, the blonde leader holding up her sword in defense until Sokka knocked it out of her grasp, afterwards kicking Rachel on her back. "Haha! Bet you never saw a Meteor Sword!" he smirked, aiming his Meteor Sword at her face. Rachel only smirked, using her Hookshot to grab his face and pull it closer, proceeding to punch at him before taking his sword and throwing him to the ground. She ran over to pick up her sword, and Sokka woke up eyes-widened when he found Rachel crossing the two in an 'X' as she pointed at his face. "HEELP! CRAZY GIRL WITH SWORDS!" he screamed, dashing away as Rachel ran after him.

By this point, both teams stood on parallel sides, facing their opponent. When Nigel and Zuko threw another Fire Punch, Jeong-Jeong appeared in their way and grabbed their fists. Eva and Katara were about to take another Water Whip swing when they were suddenly encased in water and frozen by Pakku. Toph and Angie were about to send another earthquake until both rock lines were held back by King Bumi. Fanny, Kuki, and Abby were about to charge at Suki, Ty Lee, and Mai until a puff of magic smoke appeared, Facilier appearing in their way. Sokka was able to take his sword back and was about to swing at Rachel until Piandao swung his sword and blocked both of their swings.

"Alright, kids, that's enough!" Iroh yelled, immediately ceasing the fighting. (End song.) "Honestly, can't foreigners come to town for once without some WAR resulting? ?"

Patton got his clothes back as the girls "huffed" and walked away. "Pfft. Girls." The rest of the opponents exchanged glances and gave apologetic looks, sheathing their weapons or powers.

"Uncle Iroh!" Zuko exclaimed. "Where've you been all this time?"

"I'll explain later. Where's Aang?"

"But more importantly, where's Momo? ?" Bumi questioned.

The Avatar was still trying to get away from the pursuing black hedgehog, running out of breath as he dodged Shadow's spears. "You can't run, Avatar!" However, Shadow stopped when a flying white lemur suddenly came down and landed on his face. "Argh, get it off me!"

"MOMO!" Aang yelled.

"Hnnn!" Shadow grunted, throwing the animal off of him and glaring at Aang. Aang kept his staff raised, expecting an attack, but Sonic and Marine sped over and got in his way.

"Not so fast, Shadow." Sonic told him.

Aang stared confusedly at this, then was caught by surprise when Mewtwo, Clockwork, and Grim appeared between them, too. "Go. Return to your friends." Mewtwo ordered. Without a second thought, Aang sped past the spirits and animals and headed the way they came, with Momo flying behind.

Shadow curled into a pinball and Spin Dashed past the animals, but Clockwork raised his staff to freeze him in time. With his own power, Shadow broke free of the Time Freeze and teleported above them, throwing Chaos Spears which Grim spun his scythe and defended against. When Shadow landed, Sonic shot over and ran the hedgehog over. Shadow got up and saw Marine running over, standing and quickly grabbing her fist to hold back a punch, but Marine lit her other fist with light and simply punched him across the face, knocking him over and causing the yellow Chaos Emerald to drop out. Shadow reached to grab it, but Marine stood over him and took it, smirking at the hedgehog as she bounced it in her hand. "'ere ya go, Mate!" She tossed the gem over to Sonic.

Shadow stood back up to attack the raccoon, but Marine jumped away and punched a Light Sphere at his face before walking back besides Sonic. "You know, Shadow, I know you had your issues in the past," Sonic started, "but I thought you learned a bit of common sense. You can't just attack any random person to solve your problems. Chaos Control." He raised the Emerald as it glowed and warped him and Marine. The three White Lotus men spared a glance at the hedgehog before teleporting as well.

"Shadow!" Rouge the Bat yelled, running over to help him back up. "Are you okay?"

"…Hmph." Shadow huffed, brushing himself off. "I'm fine. Let's go look for the others." With that, the black hedgehog slowly walked off to where the Avatar was headed.

Back with the others

"Sooo, wait…" Toph began, "your world has animals… that aren't hybrid?"

"Well, we have some werecats." Angie replied. "But… no hybrids like you have, apparently."

"You guys come from a weird world." Sokka said.

"You wanna see weird, try meeting someone who's never had a chilidog in his life." Hoagie smirked.

"Sounds about as real as someone never trying those tasty creampuffs." Sokka said, his mouth drooling.

"But, you guys still have bending in your world." Zuko said. "Does that mean other parts of the universe have benders, too?"

"That's what we believe." Nigel replied.

"Guuuys!" They turned and noticed Sonic and Marine speeding over to them with Aang and Momo by their side.

"Finally, you're here." Iroh said as the other White Lotus men appeared out of thin air.

"So, I see you guys are already acquainted with Aang's friends." Sonic observed.

"We… could've gotten off to a better start." Katara said, sheepishly.

"Hehehe! Oi bet if Nova were here, she'd go all loopy and troppo on you blokes for gettin' in a fight! Hehehehe!" Marine snickered.

"Now, start explaining." Aang demanded. "Who are these people?"

"Patience, Young Avatar." Iroh replied. "Let us head into my teashop in Ba Sing Se. I will set everyone up with some tea and begin explaining."

The Jasmine Dragon

The operatives and Avatar Worlders sat around Iroh's teashop as Aang tried to comprehend the story from Iroh. "So, wait a second… you're saying there's a universe, parallel to ours… where the mirror opposites of everyone's personalities and traits lives… and there's another Avatar there who… wreaks destruction and havoc?"

"That's right." Iroh nodded. "The four Dark Elements: Poison, Shadow, Psychic, and Fear."

"You sure Fire isn't supposed to be one of those elements?" Sokka asked, earning glares from Nigel, Fanny, and Zuko. "What? I'm only teasing."

"I'd stay clear of the Irish redhead if I were you." Hoagie whispered to him.

"This is bad." Aang said depressedly, shaking his head. "It was hard enough to defeat Firelord Ozai, when it was four elements against one. How am I supposed to beat somebody who bends four totally different elements?"

"Is there a way to master those elements?" Zuko asked.

"No. Only the Avatar and Negatar can bend their respective elements. No shared ones." Iroh answered.

"And if one of you is destroyed, the other gets destroyed, too?" Katara asked. "Which was why that hedgehog was after you?"

"Well, maybe you can just use energybending on him, like you did with Ozai." Sokka suggested. "You know, just glow it up and kick his can."

"Always with glowing it up, isn't it, Sokka?" Katara asked, disbelieved.

"Even if I could go against him, I'm not even sure if I can do that, anymore." Aang said. "I feel like energybending was a onetime deal."

"Aang, there's no need to feel worried." Katara replied, putting a hand on his shoulder. "Beating Ozai wasn't easy either, at first. I'm sure there's a way."

"Yeah, after a while, when the Negatar's probably destroyed everything with these Heartless guys. How do I know if I have time to 'wait for a solution'?"

"You know what I wonder?" Toph asked. "How come no one else has ever heard of this Negatar?"

"It was always supposed to be the Avatar's and Negatar's jobs to keep watch in their own worlds." Iroh replied. "But the Negatar has always been vulnerable to Darkness throughout the generations. Some have fallen to it… others have conquered. Not Gnaa, however. He is the deepest into it. He retrieved his own Keyblade and reawakened the Heartless."

"Why don't we just block his chi? That'll settle things quick enough." Ty Lee smiled.

"Yeah, 'cause chi-blocking always works fine." Mai sighed sarcastically.

"But Aang should have the strength to defeat him, shouldn't he?" Eva asked.

"There were no guarantees." Iroh said. "I cannot remember the last time the Avatar has so much as encountered his counterpart, let alone battled him. But Aang did need to be warned of these dangers. For as the Negatar has the power to awaken the darkness within a heart, the Avatar will be able to bring back the light."

KND Museum of Artifacts

"WELCOME, fellow operatives", the Kids Next Door Curator, Numbuh 101 announced to Numbuh 202 and a group of kids as he walked them down an aisle in his museum, "to the Kids Next Door Seriously Cool Museum of Artifacts and Stuff!"

"Yeah, yeah, just get on with it. Got anything good to show us?" a gruff operative complained.

"Just be quiet and let him speak." Numbuh 202 stated. "Go on, Matt."

"Thank you, Kim." Matt smiled as they stopped beside a pedestal with a curtain over it. "Today, we have an item, SO magnificent and rare, there are only seven in existence! And each one has the unique ability to alter the fabric of Space and Time! BEHOLD!" He threw off the curtain and exposed them to a glowing white rectangular gem in a glass casing. "A Sol Emerald. Pretty neat, huh?"

"…It doesn't look that good." that same boy said.

"Hel-LOO? This gem is a source of limitless power! If a villain got his hands on it, he could… turn all of our candy supply into broccoli!"

"It still looks kind of lame." another boy said.

Kim noticed the look of worry on her friend's face, unable to think of anything else to say, so she looked around and noticed a larger curtain hiding something else. "Umm… what's behind that curtain, Matt?"

"Oh, that?" Matt smiled, walking and standing in a spot where it was in the kids' eyeshot. "It's an earwax statue I asked Numbuh 191 to build. It's still in the making. It's a statue of the biggest traitor the KND has EVER known! Numbuh 23… BBY!"

A cricket's chirping could be heard over the quietness of the confused tourists. "What's the BBY stand for?"

"Uh… I dunno."

"Well, what did he do that was so bad?"

"I… don't… remember that either."

"Well, what's 'is name?" a Western-sounding girl asked.

"Um, I dunno, um… Reverend Simmons or something? BUT, what I do know is, he committed his crime sometime before his 13th birthday, and he afterwards quit the KND and ran away before they could capture him! And legend says that he ALSO locked his background files AND his very own DNA booger within the deepest confines of the KND Code Module, so that NO ONE would ever remember who he is OR be able to decommission him! Therefore, he remains a technical operative… to this very day…"

"Uh-huh… that sounds totally bogus!" that other boy shouted.

"Come on, guys, let's go to the gift shop." the gruff boy suggested. The operatives gave cheers of agreement and they all walked away, leaving only Kimberly as she approached the curator sitting on a stair in depression.

"Oh, what am I gonna do, Kim?" Matt asked as Kim took a seat by him. "I'll never get anything in my museum that catches these kids' interests."

"The Sol Emerald looked pretty cool, Matt…"

"Yeah, but I sounded like a total moron when I talked about that… Whatshisname. It's my job to know all I can about the KND's history and I don't know anything about a simple traitor. Ugh, if only I had that H.E.A.D.-S.E.T. thing that Numbuh 2030 had. I bet I can use that to find the hidden files on this operative. Too bad he took it when he betrayed us."

"Well, it's not really possible to know everything, Matt. Besides, you're still able to catch my interests." She smiled.

Matt looked up and smiled back. "Well, at least I still have your support. Hey, tell you what! I'll let you in on a little secret."

The curator led his friend into a secret room under a trapdoor, completely dark except for the only light coming from a humongous green emerald in the center which Kim could only gape at. "Whoaa…"

"THIS, Kim, is the Master Emerald. Said to be the controller of the Seven Chaos Emeralds. I think the Kids Next Door robbed it from a ship that came all the way from Planet Mobius!"

"Whoa… how come you never showed this to anyone?"

"Because with limitless power like this, it's too dangerous to present in a museum." In the background, the sounds of children screaming could be heard, but the two didn't seem to hear it. "This Emerald has enough force to… blow up the entire universe."

"I couldn't agree more…" The kids gasped and turned back to see a familiar scientist walking down the stairs with his evil grin. "So kind of you to lead me to the Emerald, kiddies. Ahh ha ha ha!"

"Wait a second! You're that Eggman creep!" Matt pointed.

"You're only half-right. I am Dr. Eggman Nega, Eggman's opposite from the Negaverse. And I believe you have something that belongs to me. Now… let me have that Emerald."

Matt got in front of Kim and held his arms out in defense. "You aren't going anywhere with this Emerald!"

"And how did you get past security and everyone else?" Kim asked.

"It was easy. A group of children are easily distracted. I gave them my toys to go play with."

The two exchanged worried glances and ran past the scientist up the stairs, finding operatives running and screaming as a bunch of robots were wrecking the place, each of them bearing the Heartless symbol on their chests. "No! My museum! Quick, 191, hide the statue in the closet!" The big-eared child pushed the wagon holding the curtained statue into a nearby closet.

"What do we do, Matt?" Kim asked as Matt took out two S.C.A.M.P.P.s, handing one to her.

"Let's take them down, Kim! Ayyy-YAH!" Matt cried, jumping down and shooting at all the robo Heartless. A squad of Devastators (giant spider Heartless robos with four legs) approached Kim, but she took her S.C.A.M.P.P. and shot at the eyes of one several times before destroying it, backing away as the others approached, charging electrical spheres and trying to shoot her.

As Matt finished off a few more Heartless, some red Heartless appeared that had no legs, but moved on a single wheel (Magnum Loaders). The bike Heartless charged and ran over the curator, preparing to shoot him with ray guns. "Kim, help!"

A fiery tornado suddenly broke in through the ceiling window, spinning around the floor and destroying the robots before stopping and revealing herself as Blaze. "Stop right there, Nega!"

"B-Blaze!"

A few feet away, a Heartless was flung away when a fist popped from the floor below it, the echidna Knuckles coming up and grabbing a Magnum Loader, throwing it into another one. "This museum doesn't belong to you!" Tails exclaimed, throwing Dummy Ring Bombs at the Heartless.

"Grrr. I don't need this. I'm taking this Sol Emerald and getting out of here." Nega decided, smashing his hand through the glass casing and grabbing the white gem.

"Oh, no you're not!" Blaze declared, kicking a wax statue of Knightbrace at the Negative, blocking his vision and getting him covered in wax. Nega dropped the Emerald as a result, allowing Blaze to run over and grab it. Nega angrily wiped the wax from his face and snapped his fingers, summoning some Defenders – purple Heartless in knight's armor and holding shields with lion's faces with chomping mouths.

Kim stepped back in terror when even more Devastators approached her and charged electric spheres. Kim noticed the closet behind her and ran in, grabbing a massive bazooka and taking aim at the Heartless. The robots exchanged frightened glances and retreated as Kim smiled. "Uh, Kim, you know that's a giant bubble-blower, right?"

"Yeah, but they didn't."

Knuckles kept his cocky smirk, using his Shovel Claws to punch through the shields of other Defenders and knocking them out. "Heh. This is easy. Huh?…" The echidna noticed a rope coming down from another hole in the ceiling window, reaching into a large hole in the floor, and his eyes widened in shock when a metal claw was pulling up a familiar giant green gem, with Eggman Nega standing on said gem and smirking. "HEY! IT'S THE MASTER EMERALD!"

"The Master Emerald?" Tails replied as they all faced the green gem with shock.

"How did it get here?" Blaze asked.

"EGGMAN NEGA! GIVE IT BACK!" Knuckles demanded, leaping up to punch at the scientist, but some flying Devastators flew in his way and knocked him back.

"Ahh ha ha! I'll collect that Sol Emerald later." Nega said as the Emerald was lifted back into their Egg Carrier. "Until then, you can hold onto it for me. Until next time, Blaze. Ahh ha ha ha!"

"With that Emerald… What'll we do?" Tails asked worriedly.

"We gotta go after them!" Knuckles decided. "Come on, let's move!"

Avatar Realms

Sonic and Marine, at this time, lied atop the roof of the teashop, gazing up at the starry nighttime sky. "It never really matters which world you're in. Sky always looks the same." Sonic said.

"Sure does, Mate."

"Too bad about Shadow, though. 'Guess the darkness really has gotten to him."

"Eh, that bloke'll be fine. 'e usually is, isn't 'e? That's what you told me."

"Yeah… but ever since we've been on this quest, it's kind of opened my mind to some things. How people can be influenced by Light and Darkness and stuff. You ever think about it, Marine?"

"Not really. That kinda philosophical stuff doesn't suit me. I just go wherever the beauty of the waves takes me. Go with the flow, or some rubbish like that. It don't do ya good to worry about what might happen in the future. You just… blow with the wind, or flow with the waves. Go wherever it takes ya, y'know?"

"Heh heh heh. I guess."

"WAH!" The ground suddenly shook, making the Mobians roll off the roof and fall in front of the shop as the others ran out.

"What's going on?" Iroh asked.

They looked up as the fat mustachioed scientist hovered in his Egg Gargoyle craft, with Orbot and Cubot sitting in the eyes' cockpit. "OHH ho ho ho ho!"

"Eggman!" Sonic exclaimed, standing up.

"That old drongo! You followed us here?" Marine asked. "How?"

"Using the Chaos Emeralds, of course. But you and I have a score to settle, Sonic. Same goes for your little snot-nosed sidekicks."

"Oh, great. Another crazy weirdo." Toph moaned quietly.

"Hurrr. Crazy weirdo, am I? Well, listen here, Blindy, since you can't see, then hear me when I say that-" The madman was silenced when Toph stomped a rock from the ground and kicked it at his face, making him dizzy while Orbot and Cubot burst into laughter.

"I may got no sight, but my ears don't need to be perfect to know where your unbearable blather is coming from."

"We have you outnumbered!" Aang shouted, aiming his staff. "You stand no chance against all of us."

Eggman's eyes widened at the child. "What's this?! The Negatar's COUNTERPART? My, my, isn't this an unpleasant surprise? At any matter, Sonic: give me the Chaos Emerald, or Miss Cream and Vanilla will suffer!"

"What?!"

"Caught your attention, did I? That's right, I've captured your little bunny friends, and locked them nice and safe on my Death Egg! As to what I plan to do with them, I'm afraid I won't tell you. Now… give me the Chaos Emerald, and I promise to spare them."

"I don't believe you for a second. Now, what are you doing with them?!"

"Ooh, wait, Oi remembah!" Marine spoke up. "Eggman's making some Robotimifizer thingy, and he used that to turn Cream and Vanilla into robots, and he wants the Chaos Emeralds to power it up and turn everyone in the universe into robots!"

"Why didn't you tell us that?!" they all chorused.

"This adventuh's been goin' on a while, Mate. Can't expect me to keep track of everything."

"Well, that's pretty much the gist of it." Eggman said. "Just hand me the Chaos Emerald and I'll spare this pathetic city."

"Who do you think I am, Knuckles? No way you're getting this Emerald."

Eggman let out a sigh. "Yeah, I didn't think so. Ahem: HEARTLESS!" At his command, legions of centaur Heartless and floating wizard Heartless appeared out of thin air. "I'll see you later, Sonic." Eggman told him, flying towards the Great Wall.

"CATCH YA LATER, BUDDY!" Cubot screamed.

"Hey! Get back here!" Sonic ran after them, leaving the others to fight the Heartless. The blue hedgehog followed the Egg Gargoyle over to the Great Wall, dashing up the colossal wall and running along the top of it as the winged craft turned and faced them. (Play the Egg Cerberus/Genesis Theme from Sonic 2006!)

Boss fight: Egg Gargoyle

The Egg Gargoyle sped away from Sonic as it sent airwaves from its wings along the ground which Sonic jumped over. The long neck of the robot smashed against the ground, causing a shockwave that tripped Sonic a little, but he still kept running. The neck lifted up and revealed laser turrets underneath, unleashing blue beams straight ahead and making the hedgehog stay to the very right. Afterwards, the gargoyle flew away from the wall and took aim with its tail cannon, Sonic dashing even faster as it sent missiles out and destroyed parts of the road behind him. The Egg Gargoyle stopped firing and got back on the road in front of Sonic, allowing the hedgehog to Boost and charge into him, doing some damage and forcing him back.

Eggman angrily recovered the device and revealed two lasers beneath its wings. Sonic stayed in the center as the lasers fired down the sides of the road, then quickly sidestepped to the right when the middle lasers fired again. The tail was also launching missiles behind it and destroying parts of the road ahead, forcing Sonic to slide off and run along the side of the Great Wall. Sonic saw the Egg Gargoyle get behind him, dashing faster as the robot tried to snap its teeth at him. Just when it was about to chomp down, Sonic dodged around an incoming lump in the wall and caused the robot to bump into it. Sonic then ran back atop the wall as the gargoyle recovered and flew back in front of him. But Sonic performed another Boost and rammed the robot's face, doing more damage.

"Critical system failure." Orbot reported. "Energy levels dropping."

"Grrr! Keep firing!" Eggman ordered.

The gargoyle hovered above the ground and made several slam-downs, making those parts of the road crumble so that Sonic had to quickly jump over them. By this point, they were making another loop around the wall to the parts that were already blown off, so the gargoyle flew far ahead and sent more missiles after Sonic, which the hedgehog used to Home Attack his way over the gaps in the road, then landing along the side of the wall and continued running. The Egg Gargoyle also flew along the side in front of Sonic, slowing down and tricking Sonic into coming closer so that it could snap its teeth at him, but Sonic saw this and quickly sidestepped left. Once the robot was behind him, it aimed its tail and sent three missiles directly at the hedgehog. Sonic saw the first one coming in and dodged to his right, letting it ram the wall. The second one was coming, but Sonic moved toward the center again, letting it crash. As the third one was closing in, Sonic noticed that same lump in the wall and dodged around it, letting the missile destroy it.

When Sonic made it back onto the wall, the Egg Gargoyle flew back in front of him, but when Sonic Boosted, the robot dodged and flew straight upward as Eggman laughed. Now hovering high up in the air, the gargoyle faced down and launched more missiles that came for the hedgehog. Sonic jumped and Home Attacked the first missile, then bounced off the other ones until he made it higher than the Egg Gargoyle. With one final lock onto Eggman's cockpit, Sonic spun into a pinball and straight at the robot's weak spot, sending it flying away.

"Heh. New minions, but same old strategy. Is that the best you got?" Sonic said cockily as the robot exploded on the ground in the distance. (End song.)

"Sonic!" Marine yelled as everyone else hurried over to the wall, looking up at where he was.

"Don't worry, guys!" Sonic yelled down. "Old Eggy never stood a chance!"

"Oh, that's what you think." Eggman retorted, attracting Sonic's attention as he and his robots came back up in his pod, smirking and directing his finger upward. (Cue Eggman's Theme from Sonic Unleashed!)

Everybody gasped in utter shock when what looked like a planet-sized portal opened high up in the heavens, and the space station that bore Eggman's mug came out. "Oh my…" Sokka looked speechless.

"Uhhh, what's going on?" Toph asked.

"Sonic! It's the Death Egg!" Tails called as he and the others were flying down in his airplane.

"Tails!"

"What? How did you get here?!" Eggman asked.

"Sonic! Eggman Nega's stolen the Master Emerald. He's taken it to that Death Egg!"

"Oh ho HO! Well done, Nega! It seems that retrieving the Master Emerald was no difficult task." Eggman smiled.

"Ahhh ha ha ha ha!" Eggman Nega laughed via intercom aboard the space station. "No task is so difficult with superior brains. Stealing a gigantic Emerald from a museum guarded by tiny children is like taking a jewel from a baby."

"Our museum?" Rachel queried.

"With this Emerald, our Ultra Roboticizer can exceed to maximum level. We will transform everyone into robots and rule the universe. And what better test run than this peaceful looking planet we've just stumbled upon?"

"Nothing could be more eggsquisite. Now… why don't you beam me up so that we can all get started?"

"With pleasure, Doctor." the Negative replied, sending a blue tractor beam straight from the base's mouth, catching Eggman and quickly beaming him up.

"Ooooh! Look at me, Orbot! I'm all glowy!" Cubot exclaimed.

"Tractor beaming always made me nauseous." Orbot said, gripping his nonexistent stomach.

"And when we get up there, we oughta change Cubot's voice chip." Eggman suggested.

"He's gonna turn this whole planet into robots?!" Hoagie asked, panickingly.

"Not if I can help it." Sonic said, jumping onto the X-Tornado's wing. "Fly us up there, Tails. It's time I cracked that egg once and for all."

"Okay. Let's go!" With that, the plane faced up and shot straight toward the space station.

The Death Egg

Within the station's control room, the eggenious opposite watched the previous battle replay on his monitor, chuckling quietly. "I am so glad you enjoy those robots, Doctor… because it's high time… you become one. AHHH ha ha ha! WAHH ha ha haaah!"


AND SO, the KND meets Team Avatar! This chapter could've gone better in a few parts, BUT… what can ya do. But next time, we will finish off Sonic's story arc and have our showdown with Dr. Eggman! Won't be as epic as the Bowser battle, but Sonic's story was never a big deal in this story. :P
