Khan was wrapped up in a shadowy explosion, so big no one could miss it. Unohana was concerned that despite looking right at him, she could no longer sense Khan's power. Khan stood there in full armor layered and draconian with a heavy shadow aura, just rolling off him obscuring any exposed area and completely distorting his appearance to anyone watching from too far a distance.
Khan's weapon had turned into a long sword, with jagged edges. On his left arm was a Kite Shield, the size of his torso, with a row of intersecting spikes that ran from top to bottom right down the middle. Unohana stood there, her combat instincts screaming at a fading distance for her to use her Bankia, but an unknown voice softly whispered in her ear saying, 'Don't you'll hurt your comrades, it's better if you submit to him, better if everyone submits to him.' Unohana readied her sword for the fight, but she was distracted by conflicting interests.
....
Yamamoto watched with growing concern. He had every confidence in Unohana's ability, but this conflict was rapidly becoming more chaotic. He was concerned over the fact that the Hollow who called himself Khan had somehow entered the field without him noticing. Yamamoto was sure he wasn't losing a step. He noticed when Kusaka and the Hollow twins entered, and he noticed when the exiles entered. Now Yamamoto was focused on this Hollow but that shadow aura enveloping him made it difficult to see, then his attention was brought back to Aizen's forces when the already biggest among them began growing to even more gigantic proportions, and another one who was dressed like some combination of a monk and priest, along with his followers began charging him directly. Yamamoto heard their leader say, "If we take out their leader, and the rest will fall!" Yamamoto felt insulted that his Soul Reapers would be so helpless as to lose this fight without him holding their hands, then he noticed that same man grow several extra eyes.
Yamamoto felt random energy on his body and realized that his attackers were trying to control him. Furious, Yamamoto burned that energy in an instant, then focused his flames on his would-be attackers they were vaporized instantly. Yamamoto then ordered, "Everyone deal with Aizen's forces, I'll keep an eye on Unohana and provide aid if needed!" Everyone answered with a "Yes, Sir!" Then they dispersed.
Yamamoto turned his attention back to Khan and Unohana, only to realize that between the one growing big and the other attacking, he had lost track of Khan and Unohana. He searched for Unohana's spiritual signature and, after a few minutes, found her unconscious on a random roof. He was confused, Unohana had cuts all over her uniform, and each cut had blood stains, but Unohana herself appeared to have no injuries. Once more, she seemed younger, or at least in terms of her spiritual pressure, as if she were 600 years younger. Yamamoto was unsure of Khan's intentions and wondered if he could manipulate time. The only thing Yamamoto was sure of was that Khan had his own agenda and it did not mesh with Aizen's.

Gant stood there with Cirucci and Dordoni, in front of them was the so-called Dark Ones. The last surviving descendants of an exiled noble house. Khan gave the orders to eliminate them with the exception of the purple-haired vixen called Benin. Gant was reflecting on his decision to follow Khan, thinking, 'I'm conflicted, following Lord Vaciar has made all of us stronger for sure, but now I don't know. We are rebelling against Lord Aizen, although I understand why, once he got what he wanted, Aizen would have disposed of all of us afterwards. Of course, Lord Vaciar made it clear the price for disobedience and failure to submit. Grimmjow will be a prime example for years to come.' Gant immediately squashed those doubts and refocused his attention on his opponents. Gant did have other questions, like even though most of them have raw power on par with or greater than those Soul Reaper Captains, no one seems to be able to sense their presence.
The fight between the Dark Ones and the Privaron Espada began and in the grand scheme of things it wouldn't be noticed by anyone other than Yamamoto who already knew about them, and more importantly, the Privarons wouldn't even have to use their real power to win.

Harribel stood there in their makeshift headquarters, standing behind her were Orihime and Menoly. Orihime's task was simple, she had to heal anyone who got to injured to fight, while Menoly's task was to protect Orihime. Harribel marveled at what Khan had achieved, and if what he said during those rare moments of simple pillow talk that she got when it was just the two of them were true, he had far grander ambitions than even Aizen. Harribel thoughts were interrupted by the sudden appearance of Nelliel, Pesche, and Dondochakka. Under Dondochakka's arms were the twins known as Yin and Yang.
Harribel said, "That's impressive, Khan just activated his release state a minute ago." The neutral tone in her voice suggested in her own way was slight sarcasm, and what she said really means was, "Did you do something foolish?" Nelliel said, "When we got into position, the one called Kusaka left to find captain Toshiro Hitsugaya and left the twins here behind. We took advantage of that and got the drop on them." Harribel said, "Good job taking advantage of an unexpected opportunity, just be mindful. Khan is serving as a distraction against those with the power to hurt us, so don't let your guard down." Nelliel, Pesche, and Dondochakka simply nodded in acknowledgment. Then Harribel injected a special concoction Khan made to keep their captives sedated during this fight. Once she was done, Harribel said, "Since you three are done ahead of schedule, I want you to help Apacci, Mila Rose, and Sung-Sun with their targets within the Vizards." They nodded and left, leaving Harribel to look at the new prisoners and silently accept that there would be a lot more prisoners to come.
....
Khan stood there for a moment, looking at Unohana. She was clearly not focused on the fight at hand, the "why" he'll have to solve another day. Khan charged at her, hoping to actually have a real fight with her before she was brought into the fold. Alas, it seems that wasn't meant to be. Unohana blocked Khan's strikes, but it was half-hearted, and she wasn't fighting back. Eventually, she had numerous cuts across her body.
Khan stood over her, dissatisfied with how the fight went down, and thought, 'I know Unohana is better than that, either Slannesh's corruption inadvertently ruined my fight or there's something else going on. I'll ask her about it later.' Khan pulled out two items from his Shadow Pocket. The first was a Temporal Restoration Spray, which not only heals injuries but restores the recipient to the prime of their life.
Khan was impressed with how Unohana kept herself in the same physical condition as when she was captain of squad eleven. As Unohana recovered, Khan used the second item, the orb of memory. The orb of memory allowed for the sharing of experiences and thoughts. This orb had two things, first was a message from Isane, and the second was all her erotic experiences during this last month. Khan was interested in how it would affect Unohana, but as he sensed Captain Yamamoto approaching, he immediately applied the orb and left.
Yamamoto would guard Unohana for at least a few minutes, if not more. He would've been obligated to stay by her side until squad four could secure her.
Khan got ready to deal with Barragan, and with his followers scattered over the field, Khan could take him out without interference. Khan got ready, unlike Unohana who was a mess mentally, Barragan should prove to be somewhat more focused, and thus he might have to try.
Khan found Barragan sitting on his makeshift throne with a perturbed look on his face. Khan appeared in front of him, sword drawn. Barragan got up and activated his power and took on the form of a skeleton in a purple robe. Without saying anything they both understood that someone was about to die, and they were each confident that it would be the other one.
