Okay... I'm a little nervous about this chapter because I made a huge build up, and I don't know if I will be able to do it justice. So bear with me, and I'll hope for the best. Also... MAJOR SPOILERS. If you are not caught up with the manga, either don't read until you are, or don't complain. Also, thank you for reminding me of his friends, because I totally forgot about them... oops. Finally, I took the liberty of creating a Bankai... hopefully you think its appropriate.

"Long time no see, Ichigo." Aizen said with a small smile. "Let's see how much you've grown, shall we?"

Ichigo narrowed his now hollowfied eyes. "Let's go," he said, raising his sword as Nel raised her lance.

Bringing her arm forward, she cried, "Lanzador Verde," letting loose her lance, now spiraling towards Aizen.

Just after Nel threw her lance, Ichigo swung his sword in an arc. "Getsuga Tensho!" The wave of energy discharged from Tensa Zangetsu and intercepted the spinning Gamuza, wrapping around it and increasing its offensive power exponentially.

In a horrible fit of deja vu, Aizen raised two fingers. Just as the lance reached him, he caught it in between them. Ichigo and Nel's eyes widened simultaneously.

"Now I see how you got your godly power," Aizen smiled, "Your Reiatsu is incredibly dense, but there is one problem. Though you now have the power of three essences never before combined, I have been bound within my own power. Had my own power not increased in density, I would have been crushed by it. I may no longer be the hogyoku's master, but the power I gained while wielding it remains. Though you and Neliel have become unbelievably stronger, you still cannot beat me."

Immediately after finishing the last syllable, he moved at a pace no one but a god or goddess could see and appeared behind Ichigo. A Zanpakuto materialized in Aizen's hand before bringing down on Ichigo.

Somehow, he raised Zangetsu just before he would have been cut. The resounding 'ding' it made bounced off the surrounding mountains. The mountains that were getting slowly crushed by the pressure on them. This was Ichigo's biggest disadvantage. Aizen knew he wouldn't raise his power to a level beyond one that would be safe for his friends, but Aizen didn't care about humans. To him, they were just playthings for his experiments. To be totally truthful, Ichigo was far stronger than Aizen, just not willing to use his power.

Ichigo jumped back from Aizen's sword as it swung at him again. Nel vaulted off his shoulders and lunged forward with Gamuza, which she had snatched up off the ground just moments before. "Midarana sutoraiki!" Once again, Aizen caught the lance between his fingers, though this time he was pushed back a couple feet. Nel jerked it out of his fingers and sonido'd behind him, swinging it like a bat and hitting him in the back of the neck with the blunt side, stunning him momentarily.

At the same time, Ichigo dashed forward swinging his sword. "Getsuga," he began as he approached Aizen, pumping an insane amount of power into his attack. Ichigo reached Aizen, the stun from the strike from Nel giving him just enough time to press Tensa Zangetsu to Aizen's stomach. "Tensho!" He discharged a red-black mass of energy directly into Aizen's stomach.

Nel just barely escaped damage as Aizen flew back from the force of the blast. Then he uttered two words that would forever chill the blood of anyone who heard it. "Shatter, Kyoka Suigetsu." Suddenly, the world became silent.

First, Ichigo saw Aizen cut Nel in two with his sword. Then, he saw Aizen appear in front of him. Ichigo widened his eyes. The man in front of him had taken one of the strongest attacks he had ever used at point blank range. And he was totally unscathed. Not even a fleck of dust was on his clothing. Ichigo watched in horror as Kyoka Suigetsu entered his heart.

Suddenly, sound returned. He looked around for several precious seconds for Aizen before he spotted him breathing heavily a distance away. Luckily, he hadn't managed to escape the explosion caused by his attack completely unscathed, leaving his form battered and ragged. Not only that, but Nel hadn't been cut in two; instead she was only unconscious. He did not, however, hallucinate the sword in his chest. He watched as Aizen walked up and slowly removed the sword from his chest.

Sound was once again fading. His eyes were closing, and the last thing he saw was a massive blur tackle Aizen and slam him into a mountain. He heard two things; however. First, was a familiar manic laughing, coming from the blur that had just flown over him.

The second was Kisuke Urahara saying, "Bankai: Kannonbiraki Benihime Aratame."

When he awoke, he heard the clashing of swords and felt Nel's soft skin on his neck. He opened his eyes and let out a shout. There was what appeared to be a very, very large woman above him. He jumped up out of Nel's gentle hold on him and away from what he now saw was a more statue-like woman. He looked around and saw Kisuke standing with a stupid grin on his face.

"You really need to stop holding back. A few hours ago I estimated the area where you would be fighting in and had Hachi create a Reiatsu barrier around it." He tossed Ichigo his sword. "Now beat him already. I didn't train you for years just to be a pushover."

"You only trained me for thirteen days!" He yelled back. He quickly ran back into the fray towards the – not so surprisingly – laughing Kenpachi Zaraki struggling to keep up with Aizen.

"THIS IS SO FUCKING FUN," He screamed in elation. "Kisuke, you weren't kidding when you said this would be worth the trouble," He laughed even more.

Ichigo pulled on his mask and joined the fight once again, this time with renewed vigor. Nel quickly joined him. This, of course, finally proved to be too much for even Kenpachi to withstand, and he backed up. Then Ichigo heard Yachiru's voice. "Ready Kenny?" she asked.

"This'll be so much fun," he said with a manic grin. He was then engulfed in yellow energy, which took the form of a skull around him. "Bankai!" he yelled, causing a powerful shockwave to expand outward, blowing everyone around him back a few feet. The being in front of Ichigo was on all fours, holding a beaten up and worn cleaver, with an animal appearance. In this form, he could move freely under this immense pressure – a testament to his incredible physical strength.

In the blink of an eye, Kenpachi was attacking Aizen once again... and Aizen was struggling. Then he jumped back and clapped his hands together. "Bakudo number 99: Bankin." A large black cube-like box immediately fell from the sky and landed on Kenpachi. As the barrier inevitably began to crack, he shouted, "Hadou number 91: Senju Koten Taiho!" An inane amount of swords composed purely of Reiatsu materialized around the slowly crumbling prison. Aizen snapped his fingers and the swords flew at the prison that had just shattered and dispersed into reishi. The shining swords stabbed into the body of the animal-like figure that was Kenpachi. He proceeded to stand, and one by one, destroy each of the swords protruding from his body.

Kenpachi quickly leapt at Aizen and resumed his onslaught, moving at an impossibly fast pace for a man his size. Slash after slash, he refused to relent. Though Aizen was seemingly effortlessly blocking every attack, each impact pushing him back only slightly. Had it been any other being, they would have been in a bloody heap at this point.

Aizen then began his counter attack. With something similar to a cross between sonido and flash step, he moved behind Kenpachi and attempted a direct slash to his back. Kenpachi somehow maneuvered around to block with such a force that he actually made Aizen stagger.

Ichigo saw his chance to strike and swung Tensa Zangetsu in a large arc. "Getsuga Tensho!"

Nel increased Ichigo's attack with her own. "Gran Rey Cero!" The two attacks merged once again in the way that no other two souls could manage. In that synchronized attack, they struck Aizen square in the back, launching him into a nearby mountain, reducing it to rubble.

Aizen's eyes burned as he stood up, pushing the rocks covering him aside. "I see you have had a great increase in strength as well, Neliel." Despite the rage filling his eyes, he had a calm smile on his face. He wasn't shaking with rage or physically affected in any other way by his anger. In fact, Aizen was standing completely and totally still. "I see I was right in choosing you to join my ranks. If Nnoitra's petty one sided quarrel with you had ended in his exile instead, you may have eventually ascended to primera."

Nel raised her lance over her shoulder, "Lanzador Verde!" she said as she threw the lance at a speed far greater than what she could achieve in just her first release. "I'm done with your words, Aizen. You always told us never to trust you, so everything you say is irrelevant." The spinning lance had just reached him at that point.

"Rippuru, Kyoka Suigetsu."

What Ichigo experienced next he could only describe as... unique. The world turned blue and time froze – except for Aizen. Though Ichigo could think and see, he couldn't move at all; only Aizen could. He saw Aizen step back and out of the way of the lance that was previously flying at him, and time resumed. The lance shot right past his left ear, leaving a breeze in its wake.

"Bankai: Giman Suigetsu." Nothing changed. There was no spike in Reiatsu, no visual change, nothing. "Rippuru," Aizen said, and he appeared behind Ichigo. The only thing that saved him was the immense Reiatsu he possessed, and the hierro that his hollow powers granted him.

The slash he suffered was shallow enough that it didn't hit anything vital. As he spun to face his attacker, he felt his back stitch closed. But he didn't have time to think about it as Aizen followed up with another slash aimed for his neck. Ichigo brought his sword up fast enough to block, but was thrown off balance when he was kicked in the chest.

Kenpachi had finally freed himself from the rubble he had been trapped in and launched himself at Aizen, cleaver raised.

"Rippuru," Aizen said softly, and stepped out of the way as time slowed. Kenpachi; however, had gained such fighting strength that he didn't need to make contact to damage an opponent. As he flew past Aizen, he slashed the air with his cleaver. Aizen's eyes widened as an alarmingly deep cut appeared across his chest.

Nel used this chance to sonido behind Aizen and impale him from behind. Aizen repeated his vocal command, "Rippuru," and once again, time slowed. He stepped out from the lance and to the side. He then kicked Kenpachi and Nel several meters away.

"How are you doing that? What the hell is going on?" Ichigo asked.

"You are aware of what my zanpakuto's ability is, yes?" Ichigo nodded and he continued. "Well, my bankai extends its power to reality. Where my shikai controls all five senses of the victim, my bankai controls reality. For example, should I be wounded; I can 'control' reality's sense of touch, and it will believe I was never harmed. You cannot touch me."

"So what you're saying is, I have to kill you faster than you can use your power. Got it." He warbled. "Getsuga Tensho!" He swung his sword in an arc as he released a crescent of power.

Nel followed up his attack with her own: "Danza de la Muerte Verde!" She leapt into the air to begin her dance. Aizen, having not seen her use this technique before, was surprised just enough to allow himself to be hit by Ichigo's attack, which dazed him long enough for Nel to connect with hers. Her movement began to blur, and gashes began to appear on Aizen's body.

Just as the dance finished, through ragged breathing, Aizen managed to grind out a "Rippuru." His wounds healed once again, and reality returned to normal. "There is no way you can kill me! Even with Neliel and that monster Kenpachi by your side." Aizen took that moment to finally incapacitate Zaraki with a 'Hado no. 88: Hiryū Gekizoku Shinten Raihō' to the face as he flew at him once again, "You stand no chance against me."

"Your arrogance is your downfall once again." A voice that surprised everyone present said. Uryuu Ishida stood a few meters behind Aizen with a small metal container, the size of a pocket lighter. "Sprenger." He turned the container so a drop of bright blue liquid fell from it, and landed on one of the five Seele Schneider forming a pentagon that Aizen was coincidentally standing in the middle of. The sword-like arrows lit up as Aizen's eyes widened in shock. Raw, blue energy raced from each of the arrows and collided in the middle, creating a massive explosion. "Now Ichigo!"

Ichigo knew what he wanted him to do immediately. "Gran Rey Cero!" He screamed as he charged the largest Cero he had ever created. He felt an enormous drain as he released the beam of energy, and Uryuu jumped out of the way.

When the dust finally cleared, everyone saw Aizen and gasped. His body was slowly disintegrating, both arms gone, Kyoka Suigetsu yards away on the ground. "Well done," Aizen wheezed, "I knew you were a sound investment. Relish this victory, Ichigo, for a new enemy will be here soon. I suggest that you ally yourself once more with Soul Society," his breathing grew ragged as more of his body disappeared. "Win over the 13 Court Guard Squads and Central 46 will have no power to refuse you. Do not die, Ichigo. I didn't put years of effort into you for you to die."

With that, the last of Aizen was gone, similar to when Ulquiorra died. Ichigo collapsed, exhausted from his fight as his horned mask dissolved. Nel rushed to his side and gave him enough power to function again, this time collapsing herself. As Ichigo stood and caught Nel, he looked to Kisuke. "Two questions: why am I still alive, and why didn't you decide to help?"

"First of all," he began, "I didn't help because I didn't want to." Ichigo gave him a deadpan look. "The reason you are still alive is because of my bankai, Kannonbiraki Benihime Aratame's. Its power is to 'reconstruct' anything it touches. So, I used it to 'reconstruct' you and your girlfriend when he cut you down." It was at that point that Kenpachi and Uryuu joined the group of three.

"That was fucking fantastic!" Kenpachi grinned.

"I had fun too! As long as Kenny's happy, so am I!" Yachiru popped up from behind 'Kenny's' back, smiling.

"Orihime let me through Hachi's barrier, but then she ran back home. Maybe she was scared to face her kidnapper again." Ishida mumbled, deep in thought. It had been almost as if she didn't want to see Ichigo. Weird.

"Kisuke, why weren't you crushed by that fight? The Reiatsu we were putting out was immense." Ichigo asked.

"Ichigo, let's just say I suppress quite a bit of my own Reiatsu." Kisuke laughed. "Now, let's go home before you pass out, shall we—" he was cut off as Ichigo collapsed. Looks like Neliel didn't have as much power left as she thought.

It was at that point that the arrancar that had followed Ichigo to the mountains had recovered and made it to where the group of 6 were standing. Grimmjow picked up Ichigo and slung him over his shoulders, while Halibel did the same for Nel, who had reverted back to her normal form when she had passed out.

Uryuu, who was alarmed at first, walked warily back to town with them after being calmed by Kisuke.

After Ichigo and Nel were laid in the bed in Ichigo's room, the chapter ended because the author had no idea how else to end it.

Jesus. That was the longest fight I ever have or will read or write 2500 words! I hope I didn't disappoint you with it, making it too boring or unbelievable, but to be honest, Aizen himself is unbelievable. I put Ishida in only because you guys reminded me, or I would have totally forgotten about him. I thought about putting in Sado (Chad) too, but I couldn't think of a good way to put him in. I took writer's liberties on Aizen's Bankai, since we have not seen it yet (if ever), but Kisuke and Zaraki were canon. Once again, let me know what you think, and if you like this story, check out Astromormy. He's not only my beta, but his story, Equal to None, inspired my story. Thanks again, and I love you all. See ya.
