This is my first story, so constructive criticism would be appreciated, but please don't excessively bash.

SUMMARY: When Ichigo's hollow attempts to take over, something odd happens. While Ichigo is fighting off his inner demon, they both stab each other in the chest and their souls truly merge. What will happen when Ichigo realizes that he has gained all the power of his hollow, and retained and enhanced all of his soul reaper powers? What will happen when Soul Society finds out?

Chapter one: The beginnings of a god.

BEEP BEEP BEEP!

"AAAAAHH SHIT!" Ichigo nearly fell out of his seat as his combat pass went off around his neck.

"Is something wrong mister Kurosaki?" Miss Ochi asked, a tick mark forming at her temple, "Or are you interrupting my class for no good reason?"

"Sorry Miss Ochi, I just really need to go to the bathroom." His teacher watched in bewilderment as he sprinted out of the room.

"Delinquent," she muttered as the door slammed behind him. "Anyway! Can anyone tell me..."

Ichigo heard his teacher's voice fading as he ran. He quickly yanked his combat pass off his neck and shoved it through his chest. After propping his body up against the wall in the bathroom, he dashed off towards the park that he felt an alarming amount of reishi radiating from.

"Oh... shit," He heard a garganta close as the last of a group of about a dozen hollows entered the world of the living. This group was headed by none other than the arrogant and ever annoying Grimmjow. Behind him were 3 adjuchas and 8 menos.

Hey Kingy, look who it is! The guy that almost killed you cause you were being a prissy!

I know who it is you prick! I'm not blind and I think I'm going to remember that damned blue haired arrancar that HURT ORIHIME!

Whoa, whoa, whoa Kingy, calm down. You know the angrier you are the easier me to control you. He laughed a long laugh.

Damn hollow. I wish he would just buzz off.

But I'm never going away~. He said in a singsong voice. Then it turned darker. Though I'd be overjoyed to never see you again.

Ignoring his hollow, Ichigo quickly took out the menos with a single, but long, flash step, using a similar technique to what Byakuya used when coming to retrieve Rukia. He then fired off three getsuga tensho's to erase the adjuchas from existence, and finally was left staring at Grimmjow, a single bead of sweat rolling down the side of his face.

"AH HAH! I knew that if I brought enough menos with me you would come running!" Grimmjow yelled with a manic grin. "Finally I get to repay the favor!"

Ichigo felt something he rarely ever felt: fear. The spiritual pressure was still four fifths as strong as it was when the menos were here. Ichigo was beginning to struggle to hold up his own weight. So be it. He may have gotten stronger, but so have I.

"BAN," Grimmjow's eyes widened as he felt a wall of reishi hit him. "KAI!" Ichigo was engulfed in a red-black orb of energy. "Tensa Zangetsu," He finished. Grimmjow grinned.

"I see! You've been getting stronger too! This will be FUN! Show me what you go—"

Their swords crashed together in an instant, and Grimmjow jumped back. He lifted his sword straight above his head. "Grind," he began as he raked his nails down its length. "Pantera!"

Immediately Grimmjow yelled "Gran Rey Cero!" And a black beam of pure destructive energy shot from the dust cloud forced up by his Resurrecció n.

Ichigo flash stepped into the beam before it could hit any nearby buildings, disintegrating half of his robes, and crumbling the mask he put on to dust.

"Shit! Be more careful! You could have hurt civilians!"

"Do you really think I care? I came here to fight you! I figured if for some reason you weren't here, I would have some fun blowing shit up."

Grimmjow laughed.

"We are taking this elsewhere." Faster than the eye can see, Ichigo grabbed Grimmjow and flash stepped away from Karakura town, a few miles into the mountains. Ichigo through Grimmjow against a cliff face, flew back and raised his sword. "Getsuga," As his zanpakuto began to radiate red-black energy, he swung it through the air in a horizontal arc. "Tensho!"

The mountain behind Grimmjow shattered as he easily sidestepped, having already recovered.

In Soul Society.

"Captain! We have just detected a massive spike in spiritual pressure originating from hollows! It appears to be an arrancar and several hollows. Wait." The Department of R&D monitor paused. "Another pressure appeared! It's almost as huge as the hollows... and somewhat similar." Another pause. "All but the arrancar's and the second pressure's have disappeared!"

"What? Alert the head captain. Let him take care of this nuisance." Captain Kurotsuchi responded in his ever creepy voice.

(Small time lapse while the head captain is contacted)

"Captain! The head captain is sending Captain Hitsugaya and Lieutenant Matsumoto to investigate."

"I told you to let the head captain deal with it. I don't care." The creepy scientist reiterated.

With Captain Hitsugaya

"Captain~" Rangiku whined, "Why do I have to go? I might break a nail if we have to fight! I spent all morning on these!"

Hitsugaya had already had a bad morning. Rangiku used all the hot water in the squad barracks that morning, and had then walked into his office naked complaining that she couldn't find her clothes. It appeared she had a hangover. Again. After locking her in the office so she wouldn't run around the Seireitei in her birthday suit, he went to find her clothes for her. He found them in plain sight, in the middle of the floor, where anyone with eyes would see them within three seconds of looking down. Apparently a hungover Rangiku didn't have eyes. Or maybe she did, and just didn't use them. Even after knowing her for years, dealing with her hangovers almost every day, he still couldn't predict anything she did.

He was reminded of that fact when he returned to his empty office with her clothes, to find the window open. By this time, the tick mark at Toshiro's temple had grown to a size rivaling the empire state – he had heard that it was large, but otherwise had no clue what it was –

and did end up chasing his lieutenant around the seireitei.

"No you didn't, you were running around all morning!" Hitsugaya almost yelled. He was at the end of his – recently – very short rope of patience.

"Fine. Let's just go through the Senkaimon already." Rangiku grumbled.

They walked out the Senkaimon the second before the mountain Ichigo scattered fell on top of them. Great, Toshiro thought, I just love getting crushed by mountains.

Ichigo didn't notice the Senkaimon open, or – spiritually oblivious as he was – sense their presence. Grimmjow was too focused on the fight to notice.

"C'mon Ichigo! You need to try harder than that!" An orb of light began to form in his hand as he raised his are straight in front of him. "Cero." Another less powerful beam of energy shot forth, this time grazing Ichigo's arm.

What the hell are you doing Kingy? Give me control! I don't wanna die!

Hell no! You'll just destroy everything! I am never surrendering my soul to you again.

Fine then Kingy, get in here!

Time froze.

Suddenly Ichigo was in his inner world face to face with his hollow on a skyscraper. "What the hell! You could not have picked a worse time! I..." Ichigo trailed off as he saw his hollow draw his white Tensa Zangetsu. Ichigo drew his black model in turn.

The hollow crashed into Ichigo without any warning, and he barely had time to block. "Stop! I don't have time for this!"

"Make time, Kingy!" His hollow howled. He seemed, for the first time since he appeared, genuinely afraid. The only thing he was afraid of was death. "I am not dying because of you!"

"Well I'm not going to die because you pulled me in here!" Ichigo attacked the hollow with full force. Aside from sliding a few feet back, he didn't do anything.

"You weakling! I'm going to take control here and now! I am the new king! You are the horse!" With a manic laugh the hollow flung himself at Ichigo almost faster than the eye can see. Just before the hollow reached him, Ichigo raised his sword. The two impaled each other at the same time. As the two blades ran through their opponents, blue reishi began to flow from Ichigo to his hollow, and red-black reishi to Ichigo. They were merging.

The two souls began to blend together, and formed into one singular one. The result was similar to the form Ichigo took when he fought Ulquiorra. With his horned mask, hollow hole, and fully recovered bankai robes, Ichigo returned to reality.

As reality reformed around him, he saw Grimmjow flying towards him. Ichigo immediately sonido'd out of the way. As Grimmjow flew at him a second time, Ichigo realized something.

He had just used sonido. And he had his horned mask on. And, most importantly – and surprisingly – he was thinking. He had an idea and he felt time slow around him.

He reached out, and confirmed his suspicions. He could feel the air. Or maybe the fabric of reality. Didn't matter. He closed his reaching fist, and held the fabric in his hand. He then pulled his hand down, and tore a garganta out of the air in front of him. Time sped up again, and Grimmjow flew through the garganta, looking absolutely pissed off. Ichigo quickly sealed the garganta again, and heard a rumbling sound.

He looked over to the rubble of the mountain, and witnessed a very, very angry Captain Hitsugaya, and a crying Rangiku, sobbing over her nails, wailing that her hard work was ruined.

As Toshiro looked over and saw Ichigo, he immediately drew his zanpakuto and raised it over his head. "Rain over the frosted heavens, Hyorinmaru!" Ichigo held up his katana, and easily blocked the ice dragon that crashed down on him.

Hitsugaya just stood there in shock. "How did you..." He froze as what he thought was the hollow making such a big fuss took off it's mask to reveal "ICHIGO KUROSAKI?"

"… H-hey Toshiro... long time no see?" Ichigo still had a hollow hole in his chest, even though he had dispelled the mask.

"EXPLAIN!" Hitsugaya nearly screamed. Damn gut. He just knew this was going to be a bad day.
