Chapter 3

Aizen Sosuke was just your everyday Shinigami. He was kind to everyone, was great for advice, and great at managing his subordinates. Totally above reproach, and loved by all of his friends and co-workers. He was almost a shoo-in for captaincy, when a spot opened. His past wasn't known, but then again, not many people knew their own pasts. But little did anyone suspect that Aizen was far more sinister then he appeared.

Aizen started out as a regular kid, born and raised by his loving mother, and supportive father in a small village in northern Japan. He was always an inquisitive child, and enjoyed learning. His mother always said he was reading before he could even walk, such was his nature. His father was proud of him, and taught him the familys sword style, rumoured to have been passed down for generations stretching back before Japan was called Japan. It was called the Konoha Ryu: Mikazuki No Mai, or Dance of the Crimson Moon. Indeed it was quite a famous style, and it utilised almost entirely unpredictable movements with ones wrist, enabling a skilled user to quite literally slip under the opponents guard, and score debilitating blows.

Aizen was an absolute prodigy in the style. He soaked it up like a sponge, it was almost unnatural how quickly he was able to master it. He was the pride of his family.

And then one day, something terrible happened. Aizen mercilessly slaughtered his entire clan, and then fled. No-one knew why. How could such a kind and caring child commit such a terrible crime? His mother, father, even his little sister. None was spared. But he didn't stop there. After massacring his family, he then joined a rival clan, and from there things went downhill. The clan was once famous for its kind caring ways, often helping a rival clan after a bloody fight, helping to heal the wounded from both sides. After Aizen joined the clan it changed.

Barbarians was a polite name for them and their policies after Aizen joined. They started believing that they were superior to every other clan, and made it their goal in life to wipe out the remaining clans, and to be top of the food chain. They spared no-one. Eventually things came to a head. At the tender age of twenty six, Aizen was bought down, and he, along with his barbaric sidekicks, were all arrested for their crimes. No-one could have known the lengths Aizen had gone to. While there was a head of the clan, it was obvious that he could not have been the one who instigated the crimes. Without any other evidence however, the clan head was executed, and the rest were spared. From this, Aizen took over. Using his charismatic personality, he convinced 4 more clans to join his, and to share their techniques. Now the master of 6 different sword styles, Aizen had enough minions to finally enact his greatest plan. A Coup d'etat. He was planning on overthrowing the Emperor himself, and making himself a god among men. Unfortunately for him, his plan was leaked before it could come to fruition, and he was executed for his crimes against the emperor.

Aizen was a very unique individual. Unlike most Shinigami, he clearly recalled his past life. The first thing he did upon becoming a Shinigami, and earning his Zanpakutou, was master the style that made his clan famous; Mikazuki no Mai. He didn't stop there however. He quickly learned that his charismatic nature had been passed on into his Zanpakutou. It's very nature suited him well, total and utter domination of another being. Not only was he a master of a sword style designed for deception, his blade and his own very nature all suited it as well. However he played his cards well. Rather then reveal his style, he took up a 'mask', almost like his very enemy, the Hollow. No-one could ever see him as an enemy.

Aizens captain, one Shinji Hirako, was suspicious of Aizen. There was no way a person could be so.. Innocent. So polite, and controlled. So he secretly started to track Aizen, determined to discover his secret. It was all for naught. With Aizens ability to fool his perception, all Shinji found was what Aizen wanted him to find. Aizen himself was curious, how is it that Hollows and Shinigami can be so similar, yet be so different? He also questioned how it was that Hollows had powers so different to a Shinigami, yet at the same time, so similar. How is it they both use Reishi, yet Shinigami use the power of their very soul, whereas a Hollow used the power of their body? It was strange. He then noticed some illicit activities done by one Urahara Kisuke. After observing him, he realised Urahara was actually trying to find a way to give a Shinigami Hollow powers. If such a thing could occur, imagine the power one would have... He would almost be a God. The strengths of both a Hollow and a Shinigami, with none of the weaknesses. He was most curious about it indeed.

After observing Urahara for a few years, Aizen decided to take a more proactive approach. He captured a Hollow, and attempted to grant it Shinigami powers. In order to do this, he drained a innocent Shinigami of his spirit powers, and thrust them into the Hollow. Thus, was the Grand Fisher born. Not quite an Arrancar, but halfway there, he had created a Hollow with Shinigami abilities. Now his curiosity was at a whole new level. Now that the Grand Fisher had some semblence of intelligence, he asked it about Heuco Mundo. It revealed to him some secrets. Unlike what Soul Society thought, the Hollows also had a distinct heirarchy. There was the ordinary Hollows at the very bottom, mindless drones. After that was the Menos, still mindless but far more powerful. After the Menos was the Gillian, which was a Menos which had evolved, and become far more animalistic. After the Gillian there was the Adjuchas, beast like creatures, who were also intelligent. They were a far step up from a mere Gillian.

But.. There was a rumour of a step above even that. That of a power so amazing that a mere 10 of them could utterly level Soul Society. That of a Vasto Lorde. When probed even further the Hollow revealed the most amazing thing Aizen had ever heard; there was a Hollow with a power rumoured to be so potent, the Hollow would worship him as a god. He was known only as the Firstborn, and it was said he was the first Hollow ever created. Aizen considered the possibilities of gaining this Hollows power. The Fisher warned him however; "You have no chance in hell at ever even scratching him." Further probes did nothing, the Fisher would rather face death then whatever this beast could inflict upon him.

Aizen however had a new goal; Grant himself Hollow powers, then subdue this 'God', and use his strength to totally and utterly conquer all life, Hollow and Shinigami.

So was born the greatest evil in the history of Soul Society. The greatest traitor that had ever graced its steps, possibly the greatest traitor that graced even the human race. He had no humanity, only an urge to rise above all, and gain a strength greater then that of the Gods themselves.

He still had a way to go yet however. First he must perfect this.. 'Hollowfication', then learn how to use it on Hollows, to create an army capable of giving him what he wanted. He set his eyes on a new goal; The Kings Key. The mythical key that is rumoured to open the gate to the Gods themselves, rulers of Soul Society.

But first, he must test his theories. His victims were many; it started out as minor disappearances. Soon however, people started to become suspicious. Even he couldn't hold the ruse for much longer. So he designed a way to blow off the heat; make them blame someone else entirely. Thus he set up his plan. He was sorely disappointed in the Shinigami so far. None of them had survived the Hollowfication process. He decided he needed to try something new; perhaps a Lieutenant. Or, if he got lucky, a Captain.

As luck would have it, the Captain and Vice Captain of the 9th squad, Kensei Muguruma, and Mashiro Kuna, were both sent out to investigate a disappearance in Rukongai. He saw this as the opportune time to strike. He infected both of them with the Hollowfication disease, causing them to both shriek in pain. As he was observing, he felt the Reiatsu of Love Aikawa, Captain of the 7th division, 'Rose' Otoribashi, captain of the 3rd division, and Shinji himself, along with the lieutenant of the 12th , 8th, and Kido corps. "Interesting," Aizen mumbled.

"What's interestin'Aizen?" Drawled Gin.

"We appear to be having some incoming company, more test subjects it appears."

"Sounds like fun."

Suddenly all of the Captains arrived on the scene, as Aizen and Gin disguised their Reiatsu and hid to observe. Suddenly, out of nowhere Kensei and Mashiro attacked the newly arrived captains. They tried to beat them back, and talk sense to them, but they were completely lost in their Hollow forms. Just before anyone could be harmed, Urahara and Tessai Tsukabishi, leader of the Kido Corps, arrived on the scene. Tessai quickly used a high level binding spell on Kensei and Mashiro, and confirmed everyone was alright. Just as Shinji sighed in relief, a heart wrenching shriek cut through them. It was Hiyori. Her face was being covered by a Hollow mask.

Quickly, Shinji rushed forward and knocked her out. As soon as that happened however, Hachi was also affected by it, followed quickly by Lisa. All of them were quickly restrained. As they were preparing to head back to Sereitei however, Shinji, Rose, and Love all collapsed on the ground, even as a mask started to form. As Shinji started to fight it, he saw Aizen, observing it.

"Hmm, interesting. It appears as if this process is affected by Reishi levels, and also by willpower. This would explain why the captains are fighting it so well..." Aizen murmured.

"AIZEN!! IT WAS YOU WHO DID THIS WASN'T IT?!" Yelled Shinji.

"Whatever do you mean Taicho? If I recall correctly, the person researching Hollowfication was.. Urahara Kisuke."

A large silence fell across the group. Urahara quickly realised he had been utterly played and out manouvered. Instead of listening to Yoruichi, he decided to rush out here, and in doing so basically screwed himself over. 3 pairs of eyes looked in shock at Aizen, the man who had pulled the strings all along.

"You BASTARD! I'll kill you" Screamed Shinji, unknowingly handing over more of his humanity to the Hollow inside. He tried to fight Aizen, but quickly collapsed, as his mask took over his entire face.

Aizen walked away, that infuriating smile firmly slapped onto his face. Tessai quickly used one of his most powerful Kido attacks, but it was all for naught. Without even speaking, Aizen used an incredibly high level Kido spell, and countered Tessai. As in dawning horror they realised what they had gotten themselves into, Gin and Aizen vanished with a Shunpo.

"We must get them to my lab, quickly. I have a way to possibly cure them, but theres only a 10% success rate..." Murmured Kisuke.

"Hai!"Yelled Tessai, using a ridiculously high powered Kido spell to freeze time, and teleport them all to Sereitei, inside Uraharas lab. He quickly went to work, using Hogyoku to attempt to cure them, but it appeared to be all for naught. Suddenly, the entire second division surrounded him and Tessai, and announced they were under arrest. They were quickly taken to Central 46, and were proclaimed guilty. Before they could be taken away however, Yoruichi quickly leapt down and freed them, helping them and the Hollowfied Shinigami out of Soul Society, and into the real world. In the shadows, Aizen was watching with a wide smile on his face.

"Attempt was a success. It appears as if only Vice Lieutenant level or higher Shinigami are able to be Hollowfied. Now, it's time to pay the Hollows a little visit..." He said, walking away with an evil smirk on his face....

A/N

Well, I enjoyed writing this chapter a lot more then chapter 2. No Naruto, but a back story of Aizen. I hope you all got a feeling for how manipulative he actually is in this chapter. Next chapter will deal with Aizen going to Hueco Mundo, in order to gain test subjects for experimenting. As we can see here, I've stated that a Shinigami must have a high reishi level in order to survive the Hollowfication process. The Hogyoko is necessary for a Shinigami to survive, as most cannot defeat their inner Hollow, Ichigo was an exception.

I'm making it differ for a Hollow however; A hollow must be at very LEAST Gillian level to become a Arrancar, but it will end up like the Grand Fisher, only half a Arrancar. If a Adjuchas class, or a Vasto Lorde is turned, they can become a successful Arrancar. There are different levels of Arrancar though. Vasto Lorde Arrancar will be numbered from 1-4 in the Espada. 6-10 will be High level Adjuchas. Any number below 10 will be low to mid level Adjuchas. Naruto is the first and only "Pure"Arrancar. All of the others are formed by Aizen using a special spell, which implants Shinigami powers inside them. Naruto however, managed to form his Zanpakutou from a Demon, not a Shinigami, and because of this his release will be far more potent. Whereas a current Espadas release is similar to a Shikai release, Naruto's release will be Bankai level strength. If you're thinking Naruto is wayy too overpowered, think of it this way. Hes a Neutral party in this fic. He doesn't give a shit who wins the war. All he wants is something entertaining.

Aizen became a Shinigami around 250 years before start of the story. He doesn't know about Naruto visiting Soul Society, as that was a highly classified secret, and wasn't leaked. He knows about Naruto thanks to the Fisher however. 100 Years before current story is when the Hollowfication stuff occurred. Next chapter will probably deal with Aizens reception in Hueco Mundo, and the next 50 or so years of his experimentation. Then I'll be leading up to the more current stuff:). I'm still tossing up on having Naruto entertain himself in the Soul Society arc. I think it would be funny if he sorta just jumped in, stole Hogyoko, and vanished. Imagine how angry Aizen would be xD.

Also, wow. Over 1,000 Hits already, and its not even a day old. Crazy stuff xD.
