Hello, this is Dregus here, and this is my first story. I don't own Naruto or bleach. With the help of my friends I was able to finally work up the nerve and do this prologue. Hope you enjoy it! And if not, then go bugger off somewhere else, because I don't want to deal with anyone whining. Flames will also be ignored.

Time: It was an absolute, inescapable thing that no one could hope to defeat. Plants, animals, humans, hollows, even the Shinigami themselves could not hope to defeat it. But not me. I had learned how to use it, and master it. With the power of time itself, no one could stand against me and my undisputed rule of Hueco Mundo. There were those who tried of course, but it merely amounted to amuse me, especially when they failed. But as time went on, I grew bored as no one raised to challenge me, leaving me left with an army with no one to use it on. And just when I was going to split my army in to two and have them kill each other…. He showed up.

At first I didn't know who or what they were, but at least it alleviated my boredom for the time being. But then Aizen had the audacity to say that I could achieve greater power, and open the door to a new world if I submitted to him!? What utter lunacy! As if I, Baraggan Louisenbairn,king and god of Hueco Mundo would ever do such a thing! I immediately had my minions attack, and I myself went and finished them off. But I did not realize that Aizen's zanpakuto had such power to completely fool all of my senses, and instead of them lying dead, it was my army! That bastard had not just defeated me, my army, and taken my throne, he did worse… he disrespected me! Looked down on me! I am a king! I am a god! Not some lowly subordinate that can be ordered around! It was on that day that I swore revenge, and I would see him fall.

I never understood Aizen's plan to sacrifice that Karakura town to make a key, to go and slay the spirit king, ruler of soul society? How absurd! I don't even care about Shinigami, or the spirit king, or any of that nonsense. And to think that all of the other Espada are actually going along with this insanity. Their all fools, each and every one of them. I know Aizen has the power of illusions, but to the extent that some of the others view him is absurd. They look at Aizen and see him as some kind of great man, but I know better. He doesn't care about any of us, not even Kaneme or Gin. All of us are just tools for him to use, and if any of us were to die, he would not bat an eye. Even I have more respect for my subordinates. But it also meant that I would not be able to get any of them onto my side and turn against him.

And when the invasion for Aizen's absurd plan finally came, things did not go well. My subordinates, Ggio Vega, Choe Neng Poww, Findorr Calius, Charlotte Chuhlhourne, Nirgge Parduoc, and Abirama Redder each died one after another. Not that Hallibel's Fracción fared any better. The foolish women never even got her Fracción to even fully control that abomination they summon. So it was no surprise that that mindless beast was killed, with them quite possibly dyeing soon afterward. She was then fighting against a young captain, while that lazy fool Starrk wasn't even taking his fight against those two captains seriously. Not that my opponents were putting up much of a fight either, but it's to be expected as they are fighting the master of aging. I decided it was time to show them true fear, and I released my zanpakuto, revealing myself as I truly am. It did not take long to take the small captains arm, which had her subordinate cut it off before it would rot the rest of her. She then ran away to do something, leaving the oaf to buy time. Not surprisingly, I got soon got bored with him, but as I was about to kill him, the captain had came back with her Bankai. At first I wasn't sure what it was, until she lifted it and fired the missile at me. Though impressive, I simply used Respira to make it detonate before it struck, and avoid damage. Then Wonderwies and Hooleer showed up, and used that god awful screech of his to blow away the smoke around me, and free Hallibel from her frozen prison.

It seemed as if we would win, but then these 8 people joined the fray, with the largest of them, a pink haired man in a green suit went to fight against me. He then sought to use his kido to trap me, but their minds work in limited fashions. Did he not think I can simply age the kido? Plants die, animals die, hollows die, humans die, and even soul reapers die. If the structures of man grow old and crumble, then so too do the Kido of the Shinigami. He once more he tried to block with a large kido made of four other spells, though it was impressive, it could not hope to contain me. As it turned out, the man said it was not meant to contain me, but to stop me from escaping the blast from that captains Bankai like I did last time! Those accursed ants!

When that missile hit me, they had actually thought that they had defeated me? They've gravely underestimated me if they think this small damage would be enough to kill me. And I showed them by easily breaking the kido, and attacking them with my Gran Caída and using it to launch Respira at them. Even though the kido user had some imitation hollow powers, it was no match for me, as my Respira soon hit him. But my victory was short lived; as that damned ant had removed his own hand, and transported it inside of me so my own Respira would be able to kill me! That accursed ant! How dare he defy a god in this way! Soon the box shattered, and most of my body had rotted away. But I had just enough strength left to throw my Gran Caída. This was my only opportunity to kill you Aizen, and I will take you with me! But before I completely rotted away, my Gran Caída disintegrated before it could hit. Damn you Aizen. Damn you to hell! I pray that the Shinigami are somehow able to thwart your plans, as there would be no greater satisfaction than in knowing everything you did was for naught. But for some reason, I feel as though your defeat was already assured…

And with that, Baraggan completely disintegrated; with the only thing remaining was his crown falling to the ground. Everyone stopped fighting for a brief moment to see the former God-King of Hueco Mundo's last moments, then resumed their fighting. Had they kept watching, they would have seen a small dark portal open up, not dissimilar to that of a Garganta and close right after the crown fell through it. And the last piece of Baraggan Louisenbairn would not be making its odd journey through the unknown alone, as a small black orb had tagged along.

X-X-X

It's was strange in the beginning of my 'life', though to be more accurate it would be more accurate to call it my 'existence'. My first memory was of when I had just been created, by that strange blonde haired man. At first, at looked as if he didn't know what I was, or what to do with me, which was strange to me. I mean, he had created me, yet he did not know what I did? How strange. Though I guess I can't blame him, as I wasn't sure what I was or could do either. I then spent all of my time in his lab, as he ran tests trying to figure out what I did. What a strange man, my father is.

I don't know what has been happening lately, but vie been sensing these strange fluctuations in the reishi, and somehow several Shinigami have been 'disappearing'. I don't know what's going on, and it seems to have father concerned as well. I wish I could help him.

Not long after the strange incidents, father and many people with strange masks on their faces appeared in the lab. I was concerned, as some not only matched the descriptions of people tou-chan talked about, but there was something wrong with them. It was like their Reiatsu had been corrupted. I could feel it slowly changing them, and warping them into something monstrous. But father believes that I will be able to help them somehow, but I don't know how, or if I can. I could 'feel' tou-chan desire to help these people, to save them. Then I felt it, power welling from deep inside of me, as if answering tou-chan's wish to save his friends. And I did...somewhat. Whatever was happening to them had stopped so their lives were no longer in danger, but I could not reverse the damage already done to them.

As soon as father left the lab to get some fresh air, I heard other voices. It sounded like they were accusing my father of what had happened to those people! I know my father can be a goof, but he would never do such a thing! After they arrested him, they took those people away as well. It was some time later before I was reunited with father. It looked like that beautiful dark skinned woman…what was her name again? I was never very good with names. Well, the cat like woman had brought those people and father. Apparently, they were going to execute those poor people that father had saved! More so, they were set up by the very same person who had committed these crimes! What kind of person would purposely use people for experiments like this? This…Aizen person is one twisted being.

It has been some time since we left the soul society, and things have certainly changed. Father has opened up a candy store of all things, with a large area built underneath it that resembles the one he had used in the soul society. The eight people father and I had helped from fully transforming have gone off to find their own lodgings, probably not wanting to owe father any more than they already have. The only ones to stay by his side are the cat woman (who could actually turn into a cat) Yoruichi and the tall glasses wearing man Tessai. It seems that they're going to hide and wait for the right time to strike against Aizen, and put a stop to his plans. But I'm not sure how long we'll have to wait.

It's been little over a hundred years; there has been no sign of Aizen initiating his plans, whatever they are. Though that does not mean things have been quite around here. Though some time ago, former captain Ishin Shiba, who had married a Quincy by the name of Masaki Kurosaki, taking on her name. How odd. I never thought a Shinigami and a Quincy would ever get along like that, let alone marry and have children. Though their first child had a great deal of spirit energy for one so young, but this seemed to be more of a curse as it attracted a Hollow, and killing the mother.

Then a few years later, Shinigami who was patrolling the area near the young Shinigami/human/Quincy hybrid, apparently found herself in danger, and nearly losing all of her powers to him in the process. Now in a very weak state, she was stuck going to father for a Gigai…and hiding me in it. I know father wants to keep me safe, but really? Aizen had brazenly used several captains and lieutenants of the Seireitei for his experiments and framed father for it. I was safer in father's hands, but hiding me in the body of this Rukia would only slow down Aizen a little bit in his plan to get me, and further his goals.

While I was 'hidden' inside of Rukia, I got to watch things through her. Though as I watched, the hybrid boy who Rukia had given her powers to was doing a decent job as a soul reaper. Though I suspect the size of his Zanpakuto makes it easier to hit the hollows, as his actual skill with it is rather poor. Quite frankly I'm surprised he had even dealt as much damage as he did to a hollow like Grand Fisher (which was apparently the same hollow that had killed Ichigo's mother) let alone survive. And the fool has no control over his own spiritual pressure, and it's affecting the people around him! I have noticed that some of his friends are not only becoming spiritually aware, but a couple of them are even gaining their own strange abilities! The tall dark male called Sado has his arm transform, and the girl Orihime who has this fairy like creatures that can form a barrier, healing, and attack! What kind of powers are those? They are not that of a Quincy, Shinigami, or hollow. Could this somehow be related to my presence as well? Father believed my powers to be able to break down the barrier between hollows and Shinigami, and that to be the extent of my powers, but I'm not so sure. If that were the case, then why can I literally feel the hybrids-Ichigo's desire to protect others? Or when Orihime and Sado felt bad about not being able fight as well, or when Rukia gave Ichigo all of her power instead of a small amount. It's like when I could feel fathers desire to help his friends. I don't understand what this means…

After that mass of hollows were dealt with, which was caused by that fool of a Quincy Uryu, things settled down, until two high level Shinigami cam to retrieve Rukia. She had left Ichigo a letter saying not to follow, but he did just that anyway. To my surprise he put up a decent fight against the weaker one, but it was only because they had the majority of their power sealed off. But as expected, Ichigo was defeated, with his soul chain and soul sleep destroyed. Even with his wounds, I know he'll survive, as father is close by.

We were then taken straight to a jail cell. We waited there for some time, until the red pineapple head called Renji came with news, that Rukia was to be executed on Sōkyoku hill. But that can't be right, as only captain level Shinigami are the only ones to be executed in such a method. Unless…Aizen plans on using it to completely evaporate the Rukia's soul with the immense amount of heat generated! But if that's the case, what has Aizen done to the central 46? Has he somehow taken control of them? Whatever the case, things are not looking good as we are then taken to the Senzaikyū to await her execution. Though of immediate concern, is that as Renji was just about to leave, he told Rukia of an unconfirmed report that five Ryoka invaded Soul Society, and one of them matched Ichigo's description. It appears as though Rukia's 'knight in shining armor' has come to rescue her.

Waiting for Rukia to be killed is quite boring, and I miss that little boy Hanatarō Yamada. He was kind of pathetic, but he at least took away some of the boredom. And no news of Ichigo and whoever he had brought with him on his mission has reached us either, other than when that bright light had appeared, meaning they had somehow broken through the barrier. The next day, Rukia is able to sense a monsterous Reiatsu, apparently belonging to Captain Kenpachi Zaraki. What kind of being is able to generate enough power for it to be sensed through Sekkiseki rock? But soon the Reiatsu faded, and unable to determine if anyone died. Shortly afterward, Hanatarō Yamada and a tall muscular man with chin-length black hair and partially missing left eyebrow wearing a vest scarf, and bandanna, making him look like a thug opened the door. But it looks as though the thug looking man, this Ganju Shiba recognized Rukia, as the one who killed his brother. Rukia even says that she was fine with him killing her, and she had no regrets if he did!

But before it could go any further, that ever stoic Byakuya Kuchici suddenly arrives. Then to my surprise Hanatarō decided to face Byakuya by himself to allow Rukia to escape, but Ganju goes out to face him instead. Not that either of them going to face him is a good idea, as neither have the strength to stand up to him. As he leaves, Rukia tries to stop him, but being in a prison mad of Sekkiseki tends to take its toll on a person, as she couldn't handle Byakuya's Reiatsu. Ganju tries to hold off Byakuya, but Byakuya defeats him with little effort, though using his Shikai of all things was over kill in my opinion. Before Byakuya could finish off Ganju, Ichigo shows up on that flying contraption father made. Rukia shouts at Ichigo to run, he fights Byakuya. After their short scuffle, Yoruichi shows up and stops Byakuya from releasing his Shikai again. She then jabs her hand into Ichigo's wound, and he soon slumps over, meaning she put some kind of drug in him. Yoruichi said that she will make Ichigo strong enough to fight him in three days, before easily escaping. Sure Ichigo is strong, but to make him strong enough to fight Byakuya in three days… unless, she plans on using the Tenshintai? But that method is dangerous! I can only hope she knows what she's doing.

After yesterdays failed rescue attempt had failed, a messenger comes and says that the execution date has been moved up to tomorrow! Aizen must be growing tired of waiting. Apparently Rukia had been lamenting about killing this Kaien Shiba, based on what I was feeling, as she did not really seem to care. Then the next morning, four guards come to escort her to her execution, and consequently right into Aizen's plans. As we are moving along, I sensed that Renji had fallen to Byakuya. As Rukia mourns his defeat, that 3rd Division Captain Gin Ichimaru approaches her.Gin, teasing her over how she greets him, points out Renji is still alive. After telling her he was trying to rescue her, Gin offers to save her friends for her. Reflecting on how much she has hated Gin since she first met him, Rukia briefly wonders what he would have to gain from such an act, only to learn he was joking. After he leaves, Rukia reflected on how Gin's lie restored her will to live, leaving her disgusted.

. Ichigo then proceeded to destroy the Sōkyoku's stand, and actually throw Rukia at Renji, who had just showed up, and they get mad at him for being so reckless, but he merely tells them to run. After running for a little while, we are confronted by the blind captain Kaname Tosen, who brings us back to the Sōkyoku hill, where Gin and Aizen were waiting. Damn it all! Now Rukia, or rather I'm right where he wants me. Aizen demanded that Renji hand over Rukia, but he refuses, but Aizen merely says that he'll take his arms as well, and almost did had Renji not defended. Ichigo then show up to try and help, but winds up nearly getting bifurcated at the waist, with Renji's zanpakuto being destroyed. Then he proceeds to begin monologue, about how he had orchestrated all of this to happen, from Rukia going to the world of the living, to him killing the Central 46 and using its power to his advantages. He had hoped Rukia would have died from the Sōkyoku, but since that failed; he resorted to a non fatal way to extract me.

And I truly wish he had never touched me, as I had never felt such a twisted, maniacal, evil and egotistical being. I was interrupted of my thoughts of Aizen, to see Byakuya save Rukia from being killed by Gin. Before Aizen can finish the both of them, the remaining loyal captains arrive, and subdue them. But my freedom was not to be, as a Garganta appears with several Menos Grande nearly spilling out of it, and the Negación used by them protecting Aizen and his flunkies. Damn, Aizen did make allies with the hollows, or more likely forced them to submit. As Aizen is about to be fully drawn into the Garganta, he announces his goal to "stand atop of the world in the heavens and take the place of the absent gods, something no one has ever done before." What a pompous ass.

It wasn't long after going to Hueco Mundo, and the absurdly huge palace called Las Noches, did I finally find out what Aizen had planned for me. By doing the same thing he had to those eight others over 100 years ago, by removing the barrier between Hollow and Shinigami, turning them into Arrancar's. But before he did such a thing, he brought me to a room, with another Hōgyoku was sitting? What is going on here? If he had already had one of his own, then why go through the complicated scheme to attain me? Unless, something is wrong with his, and plans to combine the two of us? As I looked back at Aizen's Hōgyoku, I felt a pull coming from it. As he brought me up to it, I could 'feel' its own desire to be complete. It seems as though it as not as sentient as I am. It looks as though I have no choice but to 'absorb' the other incomplete Hōgyoku. If I'm lucky, the merger will allow me to find a way to free myself of Aizen's clutches.

As soon as I finished assimilating the other Hōgyoku, Aizen immediately sent me to work on the Arrancarification of his army. But the fool has no idea that with the added abilities from his Hōgyoku, I am not as helpless as I once was. I may have 'Arrancarified' his hollows, but was able to interfere with the process, and not allowing them to achieve their full power by taking it for myself. It's not much, but I can at least help father and his friends by doing this. Though from what I sensed from some of them, very few will actually pose a threat. But the ones that I am most concerned about, are the Vasto Lorde hollows: the man and his 'other half' being a little girl, that shark woman, that gargantuan one that looked like it had a centipede for its legs, the centaur woman, with the most frightening ones being that bat hollow, and even worse, the walking skeleton in robes.

Out of all of the hollows, his is the most terrifying. But out of all the hollows I had 'Arrancarified'; this Baraggan Louisenbairn was the only one I could feel that despised Aizen to his very core. This is strange. I had thought that Aizen had fooled all of these hollows into willingly following him, but I suppose it's not surprising that he would force some of the less willing ones to join. Perhaps he could be useful in my escape, so I decided to take a risk and establish a 'link' with him, in hopes I could escape through him. After all, if I have the power to sense the hearts of those around it and materialize their deepest desire, then why can't I fulfill my desire to be free?

It's been days, and it seems as though Aizen has finished his little 'project', that being the only modified hollow, created for the sole purpose of nullifying Yamamoto's zanpakuto, Ryujin Jakka. In exchange for this, Wonderweiss's mind has been reduced to that of a child, with only enough of his mind remaining to function. I shouldn't be surprised that Aizen would do such I thing, as the old man is the only person he could not hope to defeat in single combat, not that I would help him anyway. If my plan works, then Aizen's defeat is assured.

Being in this horrible mans presence for so long, I began to hear something. At first I thought it was just his inner most desires, but this was different. For one thing, the voice was…kind and sounded like it was pleading. It was then that I realized it was not Aizen himself, but his own Zanpakuto! As I delved into the zanpakuto, I soon arrived at its 'inner world'. And it seems as though Aizen's deranged goal, has also affected this place. The land itself looked wrong. The grass was an ashen grey, the trees looking sickly and twisted, thick dark grey clouds blotting out the sun. As I went further, I saw a building, which I surmise is where his zanpakuto spirit lives. Going up to it, what once would have been a beautiful castle, was now as dark and twisted as the rest of the land. Deciding to not waste any time, I went straight for Kyōka Suigetsu. Upon entering the bed chambers where I sensed Kyōka Suigetsu, I was shocked to find that Kyōka Suigetsu was in fact a woman. She looked very much like a princess, but the current state of this inner world seems to have taken its toll on her as well. Her long hair was messy and in disarray, her skin was an unhealthy pale, her eyes blood shot from crying with bags under her eyes. Her kimono was furisode, a kimono with almost floor-length sleeves worn by unmarried women, and was a dull green with the obi being a dark blue. As soon I entered the room, she shot up immediately and looked at me. "Who are you, and how did you get here?" she asked with a strained voice.

"You do not know? Does that mean you have no idea what's been going on?" I asked, curious. If she did not know what has been going on, then Aizen is so far gone that his connection to his zanpakuto is nearly gone. "No, I have not. For quite some time, I have been cut off from Aizen and everything he does. I have tried many times to contact him, but to no avail. Now I ask you again, who are you? And what is going on outside?" She asked me. "I am known as the Hōgyoku. And to save time, I will merely 'show' you what has been going on recently via telepathy. Is that all right?" She nodded her head, and I began to 'show' her what has happened, that led up to me visiting her. As soon as I finished, she immediately fell to her knees and began crying her eyes out. I went to her side, and tried to comfort her as best I could, but I had no actual body to do so. After a while, her sobbing began to lessen, she stood up and wiped her eyes, and no longer were they dull, but full of determination and life. "I see. Aizen has gone too far now and I can no longer sit back as he abuses my power for his selfish ambitions. This world, which was once beautiful and bright, is now dark, and twisted. I had hoped one day my voice would reach him, and I could stop him, but it seems that it was only a fool's wish. I would like to help you in stopping him." Was her reply. Honestly, I was not expecting her to be so determined to stop her master. But I suppose that even a zanpakuto spirit can only put up with so much.

But the problem was how would she be able to help? Her connection to Aizen is all but gone and… that's it! Their connection! Due to how weak it is, I could use it to my advantage! Like with all of Aizen's Arrancar's, and with Kyōka Suigetsu's help, I could steal some of Aizen's own power! Not only that, but I could 'hold' Kyōka Suigetsu inside of me, when I make my escape, when the opportunity presents itself. With their connection virtually nonexistent right now, Aizen would not realized Kyōka Suigetsu and I have abandoned him until he has already lost. I told her my plan, and she agreed. As Aizen's zanpakuto, she would be able to help me siphon off enough energy from him, and use it to form a dummy Hōgyoku, made from his Reiatsu and what I can spare of the hollows I had transformed. If all goes well, then Aizen will not notice me and Kyōka Suigetsu making our escape, while my fake will destroy him from the inside out.

As Aizen and his soldiers were busy finishing preparations for their war, I was also busy trying to finish my copy in time. But things are not as smooth as I had hoped. Aizen had sent out his Arrancar forces to observe the human world and see if Ichigo is a threat. But when they returned, and the depressing one called Ulquiorra gave his report by crushing his eye, I saw something disturbing: the powers of that girl Orihime. Her true abilities are much more dangerous than I had first thought, and it seems Aizen knows this as well. It did not take him long to order her capture, and they had succeeded in doing so. She then demonstrated her power, by restoring Grimmjow's left arm, which Tosen had destroyed. Which Grimmjow then proceeded to use to kill his replacement, and take his position as the sixth Espada back. But this only changes the fact that I must work faster if I and Kyōka Suigetsu are to be free.

It did not take long for Ichigo and his friends to come to rescue Orihime. I would think it rather noble; if it were not so obvious he would do so. If they had actually though it through, then they would see that this is just a trap. Or maybe they do, and came anyway. I wouldn't put it past Ichigo to come charging here regardless if he knew it was a trap or not. As they began their invasion, they were actually doing rather well against the Privaron Espada, though their luck did not last as they ran into the actual Espada. It was not until several captains had shown up did the tide of battle change again. As the fighting was going on, Starrk had appeared with the girl Orihime, where Aizen reveals his true purpose for capturing her: to draw Ichigo to Hueco Mundo and whoever else would follow him to deprive Soul Society of military strength. After telling her that, he proceeds to walk through the Garganta to Karakura Town, where the remaining forces of Soul Society stood against him. Aizen merely responds to this by having his top three espada and their Fracción join him.

But before the fight even began, Yamamoto had trapped Aizen, Tosen, and Gin inside of a wall of flames. At least this gives them a time to deal with the espada, before having to fight Aizen. While trapped in the flames, I could sense the Shinigami holding their own and defeating all of Hallibel's and Baraggan's Fracción. Though that was merely a small victory, as Hallibel, Starrk, and Baraggan had released their Zanpakuto. To make matters worse, Wonderweiss had shown up with that hollow Hooleer. With the Shinigami as battered as they are, Aizen's victory would have been assured, had the Vizards (as they call themselves) had joined the fight, though Aizen did not seem to care. Though it makes me wonder why father and Yoruichi have not shown up yet? I would have liked to see them once more before I make my escape.

The fighting was fierce, especially those who were fighting Baraggan, and his aging powers. Especially since Soi Fon had lost her left arm, and Hachigen was hit in his right arm with a Respira. Though to my surprise, Hachigen had actually taken his rotting arm, and transported it inside of Baraggan! I never would have thought they would have been able to defeat him, let alone with his own power. Even dying, Baraggan still had the strength to lift his Gran Caída and throw it, in his final attempt to kill Aizen. I could feel his hatred for Aizen like a tempest, but more than that, his desire to have his kingdom back, to love, and to be free of Aizen's rule. With my abilities, I was able to 'latch' onto Baraggan's desires. As Baraggan's crown was falling to the ground, I used the connection I had established with him to transport myself and Kyōka Suigetsu to his crown, leaving my old orb 'form' and my copy with Aizen. The fool is so sure of his victory, that he never even noticed either of us leaving him. But when we actually got to the crown, I had to think quickly; else wise we would all 'die'. Thinking fast, I tapped into my power, and used mine, Kyōka-sans and Baraggan's desire for 'freedom' and opened up a Garganta just as we were about to hit the ground, and close it immediately, else they figure out what truly happened. I can only hope that wherever we wind up, we will have our wish granted.

And there you have it. This took me a while to do and get right, so I hope you like it. If you have any suggestions that I find of interest I will contact you. Also, I forgot to put this in at first.

For those of you who wondered, the reason could still use his Shikai is because it's a lot like when Muramasa 'freed' the Zanpakuto. They could still use their Shikai, but not their Bankai.

When the Hogyoku left its fake with Aizen, it had enough energy to do what Aizen wanted it do like in cannon, but when it began to lost power, it deteriorated, and began to work against Aizen, transforming him into that monsterous form, and destroying what was left of his link with Kyōka Suigetsu.

The reason Kyōka Suigetsu and her world looked the way it did, is because of Aizen's mental state. I mean, if you all remember in the manga that Ichigo's inner world changed from skyscrapers to small houses, and it was all underwater.
