Prologue

"Stupid Sonic," Tails Prower muttered underneath his breath. It was just after the Arthurian legend incident, where Sonic had just popped out of the book after the title was magically changed to 'Sonic and the Black Knight.' Again, the blue hedgehog had managed to net himself even more glory.

When did it end? When was he ever going to get an adventure of his own?

Deciding that it couldn't really be helped, he just watched as the blue blur was showered by the attention of his welcome back party. Amy Rose, was, as usual, all over the hedgehog and Cream the Rabbit was looking up at him in adoration. Knuckles the Echidna and Shadow the Hedgehog were pouring over the recently changed story, as was Tikal the Priestess Echidna, Silver the Hedgehog, Blaze the Cat, and the rest of the anthro-morphic animals that they had met over their adventures. Tails himself was just in a corner by himself, watching in jealousy.

He silently mused over their adventures while thinking about his inventions. Now that he thought about it, without the twin tailed fox kit to support him, Sonic would be nothing. He was the one who developed the Tornado plane series (which were all shot down by Dr. Eggman), the means of how to siphon energy from the power rings, better shoes to improve speed and drift time, and hell, even how to turn Super Sonic by using the Chaos Emeralds. He took so many hits for the blue hedgehog and hadn't even received an ounce of thanks. He had located Eggman's base over and over and wasn't even congratulated for it.

His grip on his glass tightened as the jealousy turned into hate. 'Enough is enough,' the kit thought. 'I'll get my share of glory, one way or another.'

The shattering glass went unnoticed by the party as he slipped out into his labs, right where the Chaos Emeralds were held, as well as the Sol Emeralds from Blaze's home dimension. (As to why they were there in the first place, Tails was looking for ways to harness the Emerald's energy for himself so he could go Hyper Tails on a whim. That, and he needed the energy to power the lab; without Sonic to collect rings, he couldn't pay the electricity bill).

*At Tail's Lab*

"…just gotta tweak this, and this," Tails muttered to himself as he hooked up the seven Chaos Emeralds and the seven Sol Emeralds to a machine. The machine was very similar to Eggman's in purpose; draw upon the gems energy to empower a specific being, whether it be mechanical or biological. Finally happy with the design, he closed the hatch to get some beta readings.

The small kit's eyes widened when the energy output would be well over that of Sonic's, Shadow's, Silver's, Blaze's, and Knuckle's chaos forms combined. A small grin graced the fox's face, and just as he was about to activate the machine…

"Hey buddy, what's up?" That infernal blue hedgehog showed up, making the small fox hit the activation switch prematurely.

"Nothing," came the reply as he tried desperately to stop the machine from powering up.

"You sure?" Sonic asked, seemingly oblivious to the machine in front of him. "You weren't at the party or anything. Anything happen when I was gone?"

"No," the kitsune replied, furiously typing in strings of commands.

"Okay then, I'll leave you to your lab work then," the hedgehog replied, walking away.

Tails let go of the breath he didn't know he was holding. 'That was close,' he thought. 'It's a good thing he doesn't suspect anything. Naïve idiot.'

Finally, the hatch opened up, ready to accept the subject it was designed for. With a deep breath, Tails walked in, not knowing that Sonic had stupidly flicked a switch that was crucial for the machine to work privately.

The switch itself is probably something that Eggman would've flicked. That switch removed any and all limiters of the flow of Chaos and Sol energy from the emeralds to the target. Tails himself didn't even realize it until too late.

He first felt bliss at the power flowing into his body, enhancing his speed, reflexes, strength, and intelligence. Tails felt seven more tail sprout from his tail bone, as if to signify his increase in power. This was all fine and well, but after the nonstop flow of energy, the kit got worried.

Then the pain came. The pain of every cell in your body being torn apart and being put back together again. The pain of having your teeth slowly crumble away into dust and having sharper teeth suddenly sprout from your gums. His eyes, normally blue and white, literally burst apart and replaced by a set of black and red.

The pain was too much for him. With a strangled cry, he lashed out of the machine, breaking the door. While the door shattered, he destroyed a good part of his lab as well. Seeming uncaring, he wobbled out and fell on all fours, feeling primal instincts emerge. His old form, that of a twelve year old anthromorphic two tailed fox child, faded away into that of a feral nine tailed mature fox. A grin formed on the fox's face as the energy continued to flow into him, making him grow in size, as he released a primal howl into the night.

*At Sonic's Party*

The howl's echo reached all the partying Sonic Crew's ears, making them freeze in place.

"What the hell was that?" Rouge asked.

Sensing Chaos Energy, Shadow was the first out the door to investigate, soon followed by Knuckles and Silver. Blaze sensed the Sol Energy and took off after them, leaving the rest of the party goers confused.

"Uh… What just happened?" Sonic asked no one in particular. His question was answered by a sudden rumbling noise, similar to that of an explosion. Amy, suspecting that it was another Eggman attack, flicked on the TV set, shocked at what was on.

A giant nine-tailed fox, as tall as the large G.U.N. mechanical soldiers, was wreaking havoc in station square. G.U.N. units were surrounding the said fox, their guns blazing but having no effect whatsoever. With a roar, the fox released a giant sphere of energy from its mouth, destroying the offending robots and much of the surrounding area.

"What is that!? Another one of Eggman's experiments!?" Amy yelled in horror.

"Incorrect," came Omega's mechanical voice (he was the servant of the party). "Correction: Dr. Robotnick has not been experimenting on any animals ever since his defeat many years ago."

"Then what is that thing?" Cream asked in fear.

"I do not know," the robot replied. "However, I am sensing large amounts of Chaos and Sol energies within the body of the creature. Preliminary scans indicated it is of vulpine nature."

"And what the heck is vulpine? Some sort of fruit?" Sonic asked. Yes, even he was ignorant of his friends scientific name for his species.

"In other words, a fox," Omega concluded.

"Oh, why didn't you just say so in the first place?" Sonic said, pulling his gloves on tighter. "Let's go!"

If possible, the robot would have sighed. Placing down the tray it was holding, Omega flew after him, closely tailed by Team Rose and the other party goers.

*At Station Square Park*

Humans were running in fear from a giant blood red nine tailed fox that was decimating G.U.N. forces as if they were nothing more than pathetic toys. Shadow and the others weren't doing much to stop the beast, as it just took their attacks like nothing and responded 100 fold.

"Annoying pest!" Shadow yelled, gathering energy into his palms. Throwing them back out, he yelled out, "CHAOS SPEARS!" At his beckoning hundreds of bright yellow lances of energy shot out of the black hedgehogs palm's.

"Take this!" Blaze cried, her claws bursting in flames. Lashing out one after the other, she cried out, "SOL CLAWS!" The cat's claws unleashed waves of burning hot flames that burned away most of the foliage of the area, as well as damaging the surrounding area.

"Guardian's Hammer Punch!" Knuckles yelled, releasing a giant emerald green fist shaped aura from his fists. Silver, not to be left out but having no real name for his technique, merely rose his hand and, using his telekinetic abilities, sent robots and other measures of debris at the giant rampaging fox.

"Don't leave me out!" came Sonic's voice from behind them. "Sonic Wind!" Blue waves of energy came from behind the four attackers, making them duck to avoid getting hit. The attack combined with the previous four, but as the smoke cleared, it seemed to have no effect!

In retaliation, the fox roared and unleashed a giant plume of flames from mouth, forcing all of them to step back. To follow up, one of its nine tails flashed with a bright white light, releasing an attack similar to Shadow's Chaos Spears. While most were blocked or deflected, it did manage to score a few good hits.

"Pico Pico Hammer Blow!" Amy cried, jumping high to bring her hammer down onto the creatures head.

"OMEGA OVERLOAD!" Omega said, its guns going all out, firing everything from missile barrages to lasers.

"Baton Rouge Drill Kick Combo!" Rouge screamed, following Amy but spinning down like a drill.

"BIG BELLY FLOP!" Three guesses who that was and what he was doing.

"Shuriken Shadow Clone!" Espio yelled, his ninja stars multiplying from ten to one hundred.

"Croc Fist Beatdown!" Vector yelled, releasing a barrage of musical notes from his enhanced walkman (why he calls it a fist technique is beyond me).

The attacks to the head seemed to do something, as did the sound attack. Again Sonic, Shadow, Blaze, Silver, and Knuckles did their combos, hoping to somehow weaken it, and they were met with partial success. When the smoke cleared, gone was the giant fox, but in its place was a smaller one, one that looked like…

"Tails!?" everyone cried out in shock. Shock because the fox child had gone through such a transformation and went berserk, as well as shock that he had attacked his comrades in arms.

"What's the matter?" Tails said darkly, getting back on his two feet. "Amazed at my new power?"

"What the hell did you do to yourself!?" Sonic cried out.

"Isn't it obvious?" Tails shot back, his nine tails swinging in the winds. "I absorbed every little ounce of energy I could suck out of the emeralds, resulting in this. Its amazing, isn't it?"

"You fool!" Shadow yelled, running up to strike him. "Don't you realize that you're going to kill yourself if you take in any more energy?!"

Tails merely caught the punch with one of his tails and threw the ultimate life form into one of the nearby buildings. "Me, die from an energy overdose? Highly unlikely."

"But why!?" Amy asked, unable to touch her hammer at what she had done to the fox (she thought she hurt him). "Why go through all of this?"

"Why you ask?" Tails said quietly, closing his eyes. When he opened them again, he roared out, "ITS BECAUSE I'M SICK AND TIRED OF BEING IN SONIC'S DAMN SHADOW!!! HE GOT THE GLORY FOR EVERYTHING; FROM DEFEATING EGGMAN TO SAVING THE WORLD! I WAS THERE TO SUPPORT HIM FOR EVERY ONE OF THOSE ADVENTURES, AND NOT ONCE DID I GET A 'THANK YOU!' WELL I'M TIRED OF IT! WITH THE ENERGY I ABSORBED, I'LL GET MY OWN GLORY! AND I'LL START BY KILLING YOU!" With that said, his form flickered and disappeared, transforming into that giant fox again.

As everyone drew their weapons again, Sonic just stood there in shock. After hearing that, he couldn't even look up, as it was all true…

Realizing that fighting in Station Square would get them nothing (and Sonic was being emo and useless), Shadow and Silver pooled their energies together to transport all of them into a safer spot to fight where there would be less casualties. Together, later joined by Knuckles, they cried out, "CHAOS RIFT!"

Too bad they didn't take into account that Tails had his own Chaos energy now.

Refusing to be taken alone, he made a grab for the rest of the members that had bothered to show up even if they had done nothing at all. He took grim satisfaction as they all cried out in pain as their forms changed and distort themselves. To add insult to injury, he used the power of the Sol Emeralds to erase their memories of him and the battle. As they all struggled against him, he just smiled, thinking that his revenge was complete.

He forgot to take into account that one hedgehog could resist that.

*In a Mysterious Place in the Elemental Countries*

Madara Uchiha was pacing in the plains that bordered Konoha. He needed a plan to destroy that village, but he was fresh out of ideas.

That was, at least, until a giant rampaging nine tailed fox appeared.

'This works!' thought the happy Uchiha.

Dragonkey: Er...yeah, this ideas been bugging me for a while, so i had to get his outta my head. For those who are faithfully reading my stories, don't worry, I haven't abandoned Negima just yet.

Haruhi: You better not! (grips weapon dangerously)
