Reborn as The Hollow God

The dust was slowly settling, revealing the new form Ikomikidomoe had taken. The colossal figure was now smaller; however, its reiatsu was denser than before, every movement pulsating with an oppressive energy emanating from the hollow. Its body was a vision of pure terror, as though Hueco Mundo itself had shaped its form to crush any trace of resistance.

In the distance, Cirucci swallowed hard, wiping the blood trickling from the corner of her mouth. "This thing doesn't end... Is it even a Hollow?!" Her damaged wings trembled, but she refused to let her weakness show on her face. "Dordoni, we need to rethink our strategy!"

Before she could hear a response, the monster advanced, completely ignoring the Espadas surrounding it as if they were nothing more than insects. Its attention was fixed on Baraggan, the king who remained motionless, staring back with that cold and imperial gaze.

"You, fighting in groups, old man?" roared Ikomikidomoe, his voice reverberating like distorted thunder. "Helping these weaklings like this? Don't think I didn't notice your senescence surrounding them! Were you protecting them? Just like back then?"

Yes, this was nothing new. Almost a millennium ago, when they last clashed, the situation had been similar. Baraggan faced Ikomikidomoe with his numbers; Ikomikidomoe crushed them, but Baraggan's senescence remained a problem. The two were opposites, and for that reason, they avoided fighting. But now it seemed this rematch had arrived. Ikomikidomoe felt like a fool. Not for underestimating the Espadas—he was sure that if Szayel and Baraggan weren't present, he would've killed most of them at the start of the battle. He could still feel the old monk's chains restraining his body, but they loosened as he began to recall his past. His name. He knew the source of his power was his name. "Ikomikidomoe" was garbage…

Then, in mere fractions of a second, he heard the old king's voice, mocking him.

"And you are nothing more than an abomination that dares to defy the inevitable." Baraggan didn't move a muscle, but his presence seemed to weigh on everyone there, even his allies. "Old age and time always claim what is theirs."

Beside him, Nnoitra let out a guttural laugh, breaking the oppressive silence. "Tch, he's just talking tough because he doesn't want to admit this thing's a real problem." With an expression of pure ferocity, he spun his blades. "Let me take care of this trash before it turns into a monologue."

"Nnoitra, stop it," growled Szayel, adjusting his glasses as he glared at Ikomikidomoe. "Don't you see he's adapting? If you charge in recklessly, you'll end up like Cirucci—a deadweight."

"Say that again, you damn scientist!" shouted Cirucci, pointing at Szayel angrily. But before the argument could escalate, Dordoni stepped forward, hands raised in a gesture of peace.

"Please, my friends, now is not the time to fight among ourselves!" Dordoni tried to sound conciliatory, but there was evident tension in his voice. "Ikomikidomoe is in a state that challenges our combined strength. We need to join forces and—!"

The response to the plea was a deafening roar. Ikomikidomoe charged with a sonido as fast as before, swinging a monstrous arm at Nnoitra, who blocked with his blades, only to be hurled back several meters. His feet dragged across the ground until he planted his weapons to stabilize himself.

"This bastard's stronger... faster, too," Nnoitra growled, his teeth clenched in pure rage. "But that just makes the fight more fun!"

Meanwhile, Szayel continued observing, his eyes gleaming with a mix of fascination and concern. "He's not just stronger. He's absorbing information. Every strike he makes is more efficient than the last. Fascinating... and problematic."

Baraggan raised a hand, ordering silence. His voice cut through the chaos like a blade: "Enough distractions. Szayel, find a weakness. Dordoni, keep the Menos Grandes away. Cirucci, focus on support. Nnoitra..." He turned to the Espada, whose laughter echoed even amidst the chaos. "You're good at dying slowly. Use that."

Nnoitra spat on the ground, clearly irritated, but obeyed without another word. He spun his blades and charged forward with a deafening battle cry, ready to face the monstrosity head-on.

Baraggan watched it all with a distant look, but there was something else hidden in his austere expression. It wasn't fear—that was impossible for a king like him. It was a calculated and cruel anticipation. When he first saw Ikomikidomoe, the creature had been pitiful, a shadow of its former strength. But now? He could see it was slowly regaining its power. This brought a faint sense of nostalgia.

Despite everything, the confrontation raged on, each second charged with almost tangible tension. The sound of blades clashing with flesh and the echoes of Ikomikidomoe's roars filled the battlefield. Nnoitra advanced with ferocity, his crescent-shaped blades leaving a trail of devastation as he sought a vulnerable spot in the monster. But every attack seemed to be absorbed or blocked by the Menos Grandes emerging as living shields from the hollow's body.

"Faster! Stronger! Let's see how far this goes, you bastard!" Nnoitra roared, a savage grin etched across his face as he swung his weapon in a violent arc. Even as he was pushed back by the impact, he continued charging forward, refusing to retreat.

Ikomikidomoe seemed calmer now, almost as if analyzing his opponents' attack patterns.

"You've learned nothing, have you? You fight as if this were a simple battle..." His voice reverberated again, filled with disdain. "But this is an execution."

The creature's arm lashed out like a whip, striking the ground with enough force to create a crater. Nnoitra barely dodged, but the impact generated a shockwave that momentarily destabilized him. He growled in frustration, his eyes glowing with determination.

On the other side, Cirucci attacked with precision, firing projectiles from her wings. However, the attacks were absorbed by the small Menos Grandes constantly emerging from Ikomikidomoe's body, serving as improvised barriers. She gritted her teeth, feeling her frustration grow.

"This is useless! He's using those damned Hollows as shields, and they keep regenerating!" she shouted, struggling to keep her composure.

"I warned you," Szayel responded, his voice cold and calculated. He observed the creature like a puzzle waiting to be solved. "But no, you'd rather act like savages instead of using your minds. This Hollow isn't like the others. He evolves. Every second, he becomes more dangerous."

Dordoni, who had been trying to hold back the Menos advancing at the edges of the battle, shouted, "If he evolves, then we have to finish this now, before it's too late!"

"Easier said than done," grumbled Nnoitra, blocking another attack that nearly crushed him. He staggered backward, the impact reverberating through his body, but he didn't lose his balance. "So, genius, got any bright ideas, or are you just going to stand there babbling?"

Szayel adjusted his glasses, a thin smile forming on his lips. "I'm already working on it. He can absorb reiryoku-based attacks and endlessly create those Menos, but that consumes energy. We need to overload him, force his body to expend more than it can regenerate."

Cirucci raised an eyebrow, clearly skeptical. "And how exactly do you plan to do that? Attack faster? Because that's not working!"

Baraggan finally spoke, his deep voice cutting through the argument. "It's not your place to understand. Follow orders." He raised his hand again, and the feeling of senescence intensified. The edges of the battlefield began to age, stones crumbling into dust as the king exerted his power.

Ikomikidomoe laughed, a guttural and macabre sound that reverberated like thunder. "Time? Do you think you can defeat me with that again, Baraggan? Your trick already failed once!" He advanced, ignoring the attacks around him, his presence dominating the battlefield.

Ikomikidomoe surged forward with a devastating sonido, the space around him distorting under the pressure of his reiatsu. Dordoni was the first to react, moving in a desperate attempt to contain the monstrosity. He wielded his wind tornadoes with impressive agility, trying to create a barrier of attacks to slow the hollow's advance.

"I won't let you through so easily, monster!" Dordoni shouted, sweat dripping down his forehead as he struggled to maintain composure in the face of such overwhelming power.

But Ikomikidomoe showed no interest in playing games. With a brutal motion, he slammed the ground with one of his claws, generating a shockwave that sent Dordoni flying like a ragdoll. The smaller Espada crashed heavily, coughing blood as he tried to stand.

"Pathetic," said Ikomikidomoe, his voice echoing with disdain. "You're nothing but distractions. The real threat is still there." He directed a sharp gaze at Baraggan, as if daring the ancient king to act.

Cirucci seized the distraction and flew in for a surprise attack. Her energy feathers spun with deadly speed, aimed directly at Ikomikidomoe's head. "I won't be underestimated by you, freak!"

For a moment, it seemed like the attack had worked. The discs hit their target, but instead of causing damage, they were absorbed by the monster's extremely dense Hierro. Cirucci's eyes widened, paralyzed by the realization.

"I already told you," Ikomikidomoe roared, extending one of his clawed arms toward her. "You're nothing but annoying insects!" Before she could react, his arm whipped through the air, striking her with force. The impact hurled Cirucci into one of Las Noches' distant pillars, which collapsed on top of her.

"Cirucci!" Dordoni shouted, still struggling to get back on his feet. But Ikomikidomoe was already upon him again, moving with impossible speed for something of his size. With a devastating blow, he smashed Dordoni into the ground, leaving him unconscious in an instant.

"Two are already down," murmured Szayel, watching the scene with an expression that mixed fascination and tension. He adjusted his glasses again, analyzing every movement of the creature. "If we continue at this rate, even the strongest won't stand a chance."

Nnoitra, however, laughed. It was a crazed laugh, but full of determination. "Ah, finally!!" He charged forward with his blades, ignoring any sense of caution. "You're strong, I admit it. But let's see how much you can take, you bastard!"

Ikomikidomoe took Nnoitra's attack head-on, his claws clashing with the Espada's blades in an exchange of blows that shook the ground. Despite Nnoitra's aggression, it was evident he was being pushed back. Each of Ikomikidomoe's strikes seemed more calculated, more precise, as if he were learning to completely neutralize his opponent's fighting style.

"You're persistent, I'll give you that," said Ikomikidomoe with an almost amused tone. "But persistence without purpose is just stubbornness." With a swift motion, he dodged Nnoitra's blades and landed a direct blow to his stomach, sending him flying and tearing into his tough flesh in the process.

As Nnoitra struggled to get up, coughing blood, Szayel finally intervened, firing multiple Gran Rey Ceros from his tentacles directly at the base of Ikomikidomoe's body. It was a calculated attempt to find a weakness, a vulnerable point. But once again, the energy from the Ceros was absorbed.

"I expected more from you, Szayel Aporro Granz," said Ikomikidomoe, his voice now tinged with mockery. "The brilliant scientist among the Espada... and the current Espada 0... Is this all you can do?"

Szayel didn't respond immediately. He simply adjusted his glasses again, his eyes frantically analyzing the monster while suppressing his own urge to leap at Ikomikidomoe like a beast.

"Roar of the Dragon!" Ganterbaine, who had been waiting for an opportunity, launched a surprise attack with all his might, releasing a dragon-shaped wave of energy aimed at the evolved Hollow.

However—

"OUT OF MY WAY!" Charging another Gran Rey Cero directly from his single eye, Ikomikidomoe completely overpowered Ganterbaine's attack. The Espada was soon engulfed by the explosion, his body burned to a crisp. He fell heavily onto the sands, now turned to glass, with a resounding crash.

"Tch... This is getting annoying. Hmph." Tentacles soon wrapped around Ikomikidomoe's body. Turning to face his current opponent, he was met by a massive octopus-like figure trying to devour him while restraining his smaller frame.

"GIHAHAHA! NEVER UNDERESTIMATE ONE OF THE ORIGINAL ESPADA! ARO AARONIERO!" The dual voices of the Espada echoed as he held Ikomikidomoe in place.

"LANZADOR VERDE!" Nelliel seized the opportunity to attack with her spear, aiming once more at the Hollow's eye.

And the supposed target? What was he thinking?

'Hmm… If 0 and 3 couldn't hurt me at all... WHY DO 9 AND 4 THINK THEY CAN??'

Increasing his Reiatsu, the Hollow used his superior strength to break free, enveloping his body in his Reiryoku. This burned through the gelatinous, soft body of the 9th Espada. In a swift move, the ancient Hollow grabbed Aaroniero and used him as a "meat shield," allowing Nelliel's spear to pierce directly through the smaller Espada's core.

"GAAAAH!" The resulting explosion of energy came from a Cero fired directly through Aaroniero by Ikomikidomoe, hurtling toward the 4th Espada, Nelliel.

With a quick move, she opened her mouth and swallowed the Cero, firing it back with even greater force—a Cero Doble, one of Nelliel's techniques.

However, taking a Gran Rey Cero with this method left a massive impact on her body. She coughed up blood, her entire body aching from the strain.

Despite this, the Hollow simply vanished from the area of impact, reappearing directly in front of Nelliel. She barely had time to raise her spear before being crushed by Ikomikidomoe's claws, tearing through her Hollow mask and body armor.

'Gah! His claws… they're like katanas!'

And so, another Espada fell.

At this moment, out of the original nine Espada, only three remained standing—the strongest trio: Baraggan, Pikaro, and Szayel.

The Pikaro circled above Ikomikidomoe like vultures awaiting the death of a dying animal.

Pikaro had—or rather, shared—a childlike mind, dividing the world into "good people" and "bad people" from their perspective. They refused to harm "good people" but would kill and devour "bad people." And to them, no one was worse than Ikomikidomoe.

The Pikaro soon began to gather around Ikomikidomoe, forming a circle in the sky. They unleashed a new technique with this formation.

**Chutsu Cheria.**

They transmitted their "sounds" to each other through dense reishi, creating an anomaly above Ikomikidomoe—a black hole that appeared in the air, sucking all the reishi into its artificially created singularity.

Black holes are hypermassive gravity wells that cause catastrophic damage, where not even light escapes. Normally, such an attack would cause irreparable damage to both the enemy and the surrounding area. But there was a flaw in this technique—one that the Pikaro's childlike minds could not comprehend.

A higher Reiatsu can always overpower a weaker Reiatsu-based technique.

And Ikomikidomoe's Reiatsu, now closer to his original level in his new form, had surpassed the Espada in this regard.

Which meant—

"BOOOOM!"

"GAAAAH!"

"AAAAH!"

"KYAAA!"

The Pikaro's black hole and their gathered forms were dissipated and torn apart. Normally, Ikomikidomoe would hesitate to harm childlike beings. But his patience had run out. Without hesitation, he fired a Gran Rey Cero infused with his dense Reiryoku at the small, childlike Arrancar, crushing them like insects.

"Enough of this." Baraggan's voice cut through the air, heavy and imposing. He stepped forward, the aura of senescence around him intensifying. Everything nearby began to age rapidly, including some of the Menos Grandes that Ikomikidomoe was creating.

"Finally," murmured Ikomikidomoe, a gleam in his eye.

As Baraggan advanced, the tension on the battlefield grew. It was clear that, while Ikomikidomoe had easily dominated the other Espada, this confrontation would be different.

"Don't face him alone, Baraggan. I've waited long enough, and I plan to fight in this too! I see tricks won't work on him anymore... I think only PURE STRENGTH can defeat him!"

Despite everything, Szayel, who liked to present himself as a scientist, seemed just as excited as he appeared. His thirst for blood filled the area.

The dust raised by the previous battles began to settle, but the tension in the air was suffocating. Baraggan Louisenbairn stood still, emanating his reiatsu, which seemed to erode even the very existence around him.

Behind him, Szayelaporro Granz, the self-proclaimed perfect being, was almost unrecognizable. His usual cold and calculated composure had been replaced by a wild frenzy. He trembled, not from fear, but from anticipation, the bloodlust burning in his eyes. His bloodthirsty nature had now emerged.

Ikomikidomoe, the smaller creature of condensed power before them, did not move hastily. His body pulsed with unstable reiatsu, a force so overwhelming that the air around him vibrated. He was a monster in terms of evolutionary progress, seeming to mock the laws of Hueco Mundo. Menos Grandes continued to emerge from his flesh, hurling themselves at their enemies like disposable puppets.

"This monster..." Szayel whispered, his hands squeezing the air as if already gripping Ikomikidomoe's throat. "I want to see how he breaks... how he bleeds..."

"Control yourself, fool," murmured Baraggan, his deep voice echoing. "This thing is not something you can face with impulses. Everything succumbs to death. Even him."

Szayel did not respond. He charged forward like a beast, without thinking, his claws and tentacles extended.

Ikomikidomoe quickly countered, his speed surprising for something so massive. With a brutal movement, he hurled one of his powerful arms at Szayel. The Cero Espada dodged instinctively, but the force of the strike created a shockwave that threw him back. Szayel, however, landed laughing, his teeth stained with blood from being struck squarely in the face.

"More!" he yelled, as though pleading for more violence. With an almost animalistic speed, he ran toward the monster, completely ignoring the danger. He landed a series of powerful tentacle strikes on Ikomikidomoe's arm, these tinged with destructive Reiryoku. The impact was insignificant against the creature's regenerative flesh, but Szayel seemed undeterred.

Baraggan, watching from a distance, did not move a muscle. He knew it was only a matter of time before Szayel made a fatal mistake. "Idiot."

As Szayel engaged in a desperate physical combat with Ikomikidomoe, Baraggan finally moved. He stepped forward, his aura of Respira expanding like a mantle of death. The Menos Grandes that had been released by Ikomikidomoe to surround them began to crumble instantly, their bodies decaying in mere seconds.

Ikomikidomoe sensed the threat and turned his single eye toward Baraggan. With a roar that echoed like thunder, he raised one of his arms and unleashed a blast of condensed Cero toward the king. Baraggan raised his axe, dissipating the blast as though it were nothing.

"Weak," he murmured, advancing slowly, each step corroding the ground beneath him.

Ikomikidomoe reacted, using the momentum to throw Szayel with a shockwave roar. He advanced brutally, his strikes quick and heavy.

While Baraggan distracted Ikomikidomoe, Szayel tried once again to attack. He jumped onto the monster's back, firing Ceros in a mad laugh at its flesh. The scientist roared in ecstasy, tearing at pieces of tissue with brute strength.

"THAT'S IT! DEATH! I LOVE THIS!!" Szayel shouted, but his voice was more a scream of madness than a challenge.

However, Ikomikidomoe's regeneration made Szayel's efforts futile. Before he could continue, one of the monster's massive arms grabbed him, slamming him into the ground with brutal force. The impact cracked the surface of the Las Noches sands, and Szayel screamed in pain, but did not stop fighting.

Even trapped, he tried to hurt the monster, but his strength was dwindling. With each passing second, the difference between them became clearer. Unlike Baraggan, who was maintaining his distance and attacking from afar, Szayel was the one taking all the physical and destructive damage head-on, injuries that accumulated more and more.

"________"

It was then that Ikomikidomoe let out his roar. A guttural, deafening sound that seemed to tear the very atmosphere. The spiritual pressure around him exploded, creating tornadoes of reiatsu that spread across the arena with destructive force.

Baraggan, who had maintained his composure until now, took a step back. The tornadoes not only repelled his Respira but also forced him to retreat. For the first time, the king seemed slightly disturbed.

"Interesting," he murmured, but his voice carried a hint of frustration.

Szayel, already injured, was thrown far away by the violent winds. He collided with a pile of debris, blood streaming down his face. Even so, he tried to rise, laughing weakly. "This... this is the power I wanted to see..."

The winds began to harm even Baraggan, cutting through the bones of his Resurrection like invisible blades. The aura of senescence was being directly challenged, something he rarely experienced.

"You're more and more like the Ikomikidomoe I knew... old rival," Baraggan admitted, his voice filled with both disdain and recognition.

Baraggan attempted to attack again. He raised his axe and unleashed a massive wave of senescence, but the tornadoes of reiatsu absorbed the blow, neutralizing it before it could reach Ikomikidomoe. The Hollow took advantage of the opportunity to advance, his speed even more impressive amidst the chaos.

With a devastating strike, he hit Baraggan directly, sending the king flying backward. Baraggan crashed with a thud; the impact had been significant.

Szayel, still lying on the ground, laughed hysterically. "Baraggan-sama... maybe death will reach you too, after all."

Baraggan, struggling to rise unsteadily, cast a cold glance at Szayel but did not respond. He was focused on Ikomikidomoe, who was now slowly approaching, his overwhelming presence dominating everything.

Baraggan murmured. "He's not just brute force. I had forgotten that this was why we made that deal in the past."

The battle would continue, but it was clear that the balance had shifted in Ikomikidomoe's favor. Baraggan and Szayel were at a disadvantage, forced to retreat before the monster's crushing power.

As Baraggan planned his next move, Szayel watched the monster with sick fascination, as though already planning how to study—or use—it in the future.

"This isn't over," Szayel murmured, a bloodied smile on his face.

The air around them trembled.

Baraggan, even with his kingly presence reducing everything to dust, struggled to maintain his composure. Szayel, bloodied and consumed by wild fury, still tried to rise after the devastating damage he had suffered. And Ikomikidomoe remained mostly unharmed, his massive form regenerating through the pulsating waves of reiatsu he consumed from the air around him.

However, before the confrontation could reach its inevitable conclusion, an overwhelming spiritual pressure descended on all of them like an inescapable cloak. It was not just reiatsu; it felt as though existence itself was forced to bend. Baraggan, Szayel, and even the colossal Ikomikidomoe stopped for a moment, their attention turning to the figure calmly walking through the chaos.

Sosuke Aizen, who had previously only been observing, was now interfering in the fight.

Beside him, Gin Ichimaru wore his sly smile, and Kaname Tōsen, as always, exuded an aura of seriousness. Aizen slowly advanced, his presence completely dominating the battlefield.

"Ikomikidomoe," he said, his voice cutting through the air like a sharp blade. "I believe we've had enough for today."

The colossal hollow growled, his jaw opening in a threatening roar, but he did not attack. His half-closed eyes showed more than fury; there was caution. He knew the man in front of him was capable, and he knew that facing him would not guarantee victory.

"You think you can just order me around, Shinigami?" Ikomikidomoe roared, his voice reverberating like thunder.

Aizen smiled, indifferent to the explicit hostility. "I do believe so." He took another step forward, and his reiatsu exploded, dominating the atmosphere and eclipsing even Baraggan's deadly presence.

Baraggan again felt discomfort. He knew Aizen had power; after all, he had been forcibly recruited by the Shinigami. But seeing him in action like this... was something entirely different.

"Ikomikidomoe," Aizen continued, his voice now carrying an undeniable authority, "your power is formidable, I won't deny that. And, at this moment, you could even challenge me." He slightly tilted his head, as if pondering. "But, let's be honest: such a fight would be long and devastating. Not just for you and me, but for everything around us. And you, despite all your strength, must be as aware as I am that prolonging this conflict would be pointless."

The giant hollow paused in his path again. It was more out of frustration than challenge. He knew Aizen was right. He had already claimed his revenge with the battle, and continuing would only bring more complications than benefits.

"And if I simply devoured you here and now?" Ikomikidomoe retorted, though his posture already indicated he was no longer in a stance for conflict.

Aizen smiled calmly. "You could try, but I'm not the only one you'd face." He subtly gestured to Gin and Tōsen, who immediately released their own spiritual pressures, reinforcing Aizen's statement. "Not to mention that my remaining Espada will not stand idle. No matter how injured they are, you'll end up surrounded."

The hollow glared at Aizen, his single eye burning with frustrated rage. But after a long moment of tension, he snorted and backed away slightly.

"Fine, Shinigami," he said in a tone laden with frustration. "The agreement I made with Baraggan, a Millennium ago, now applies to you. Don't interfere in my affairs, and I won't interfere in yours."

Aizen's smile widened subtly, but his eyes remained cold and calculating. "A fair agreement."

With that, Ikomikidomoe began to retreat, opening a Garganta and dissolving his immense form into the darkness. But before disappearing completely, he cast one last glance at Aizen, as if evaluating the man one final time. Then, with one last look, he crossed the portal and vanished.

Silence fell over the battlefield, broken only by the sound of the wind sweeping across the desolation of the remains of Las Noches. Aizen remained still, watching the spot where Ikomikidomoe had vanished.

"Interesting," he murmured to himself, his eyes gleaming with a new idea. "I wonder... if the Hōgyoku could create life forms and evolve the Espada if it had a fragment of Ikomikidomoe's evolution... something to think about."

Gin chuckled. "Planning something new, Captain?"

Aizen did not answer immediately. Instead, he turned his gaze to the remaining Espada. Szayel was kneeling, clutching his injured flank, but something caught Aizen's attention. From within Szayel's open and bloody ribcage, something was emerging.

It was a figure that seemed to grow the further it detached from Szayel, but still impressive: a blonde hollow, shaped like a bull, slowly separating from Szayel's body, as if it had been generated by him.

Aizen raised an eyebrow, intrigued. "How fascinating..."

He took a few steps forward, observing the newly born creature before turning back to the Espada. His smile became colder, more threatening.

"What should I do with you?" he murmured, his voice echoing across the vastness of the ruined desert that Las Noches had become.
