Fusion

(Author Note)

I am honestly a bit sad that I didn't get any feedback on the Stand picture I created. Lol, I'm joking. 

But please do tell me what you think about it.

The time had come. Yes, the time had finally come for Oetsu to do the unthinkable. He was going to fuse with the Eight-Handled Wheel. 

The Hyperbolic Time Chamber, à la Oetsu had been completed after a few years and he had also taken a while to train with his Stand and modify it more. The fact that he could feed 'Master's Hammer' with any metal and he could then use this metal infinitely, was broken and so much fun.

He began to use 'Master's Hammer' to build the Hyperbolic Time Chamber and modify it. The power of 'Creation' was seriously versatile and Oetsu trained with it inside the HTC after it was completed. He tried to create sequences of moves to then use them in a fight. He knew that it was dangerous to follow memorised sequences because he would lose against enemies who were able to read and predict his next moves.

But Oetsu was not the most talented fighter. On the contrary, he was actually quite bad. That was also visible in his fight against the Schutzstaffel and then Lille Barro. He used his speed and Sayafushi to kill them ... and that was it. That was all there was to his powers.

But this Oetsu didn't want that to happen. So what he planned was to come up with different moves and create a moveset which he increased until he didn't have to anymore. He wanted to get a feel and a deep understanding of his powers. 

.

.

But now it was time. It was finally time for him to fuse with his ultimate creation. The Eight-Handled Wheel of Oetsu Nimaiya. The ultimate tool which should theoretically grant him the ultimate powers of evolution and adaptation. His future growth was incalculable should the fusion work out as planned. And he was 98.353% sure that it would work out. 

The only thing missing after that was strong opponents to fight against and use his powers to their fullest. He already had plans. He might go to the world of Dragon Ball to fight some of the gods of destruction or even some of the Angels. It would allow him to learn their techniques and improve his martial arts. 

Another idea which he preferred actually, was the world of One Punch Man. This beauty also had some seriously powerful beings who were worth fighting. Oetsu had fed the soul of Awakened Garou to the Hogyoku and knew how powerful he was. He was talking about the future Garou who taught Saitama how to travel to the past with martial arts. 

But that was talk for the future. Now it was time to fuse with his life's work.

(Oetsu POV)

I entered the Hyperbolic Time Chamber à la Oetsu and began to prepare all the things that I wanted. I had improved some things in the meantime but not much. If I didn't do it now, I know that I would find thousands of things to add and would then never be satisfied. 

But this was a good product. This was my life's work. I had waited thousands of years to finally be able to fuse with this. 

I have created an entirely new 'chamber' for this process alone. I used some physics and maths and then mixed it with some mumbo-jumbo to create a fusion reactor. But this fusion reactor didn't fuse two lighter atomic nuclei to form a heavier nucleus while releasing energy. No, this fusion reactor did something entirely different.

I placed the finished EHW of Oetsu Nimaiya in the correct spot that I had created and added all the energy cables that were necessary. The power for this was ... monstrous. I had to create eight separate reactors for each of the handles and one to jumpstart the entire process. 

I value safety and would rather the process be stopped than everything exploding. There were numerous failsafes added. I didn't want anything to malfunction or have a bad effect because there were no stops. 

Then I got inside. I took off all my clothes and strapped in on the metal bed. The top of the smaller chamber closed. It looked similar to the one that turned Stever Rogers into Captain America.

(3rd Person POV)

The big fusion reactor closed itself as well. The power of the Arc Reactors pumped the different sides full of energy and began to heat each of the eight handles. The heat began to melt the handles. The fusion reactor was designed in a way that allowed all of the melted substance of the handles to flow down towards the rotation cradle. 

There the fusion reactor began to spin all of the melted handles at the same time and at a specific frequency. The speed increased and the heat which was generated was used in the process as well. Everything depended on the Hogyoku, which formed the heart of the EHW. 

The Hogyoku was slowly lowered from the top down onto Oetsu in the centre. Until it was just above his skin. After that, moulds were formed around the Hogyoku.

All the melted parts of the EHW, which were now completely mixed, began to flow into the mould until they had the shape of the original EHW. 

This part took about 5 hours. Now it was time to let the substance cool down so that the final step could take place. 

After 10 more hours, the EHW was completed with the Hogyoku as the centrepiece and the final fusion could now begin. 

Once again, the fusion apparatus was pumped full of energy. The EHW slowly descended until it had reached Oetsu's skin. Now 8 scalpels became visible, which made 8 precise and fast cuts. 

Blood flowed from the wound and soaked the EHW. After a moment, the EHW began to glow strongly until it was no longer visible. 

If Oetsu had been conscious, he would have screamed out loud. This part of the fusion was very painful. Fortunately, Oetsu had already prepared for this. 

Every cell in Oetsu's body was infused with very special energy and the cells began to change. A cycle of destruction and rebuilding began and Oetsu's basic substance changed. His energy reserves were destroyed and rebuilt. 

His whole being was renewed and not just his physical body. Oetsu's soul was also affected. It was actually the soul that was the target of the fusion and not the physical body. That was also the reason why all the cells were destroyed again and again until there was nothing left and then rebuilt. 

If Oetsu hadn't been immortal, he would be more than dead now. His soul would have exploded. But that wasn't the case now. He was destroyed and rebuilt over and over again. That had one big disadvantage.

The drug that Oetsu had taken to anaesthetise himself was also destroyed ... So every time he was rebuilt, he suffered the worst torment imaginable. 

.

.

After countless cycles of the same process, the destruction of Oetsu's body stopped and he fell into a very deep coma ...

How long it lasted ... was unknown. Oetsu only knew one thing. When he regained consciousness, he felt like he was in someone else's body. All the movements his brain wanted to make were carried out limply and awkwardly. Even blinking was difficult. 

The fusion reactor had long since been switched off. The smaller chamber opened and Oetsu felt for the first time since ... forever air on his skin. 

Oetsu stumbled out of the chamber and was assaulted by a killing headache. He was unsure what it was but, he was sure that the pain would kill him for a moment. His senses were about to kill him and the harsh environment wasn't helping right now. 

"~K-k-ki-kima--ruuu!~", Oetsu tried to call Kikimaru but he couldn't. His throat felt sore. Thankfully, Kikimaru was observing the process of his master and noticed that there was a change. The time outside was about 500:1. Oetsu managed to improve upon it. 

.

.

The door to the Hyperbolic Time Chamber opened and Kikimaru along with his Zanpakuto walked in. Each one carried something that Oetsu might need. They had worried faces ... all of them. It seemed they were worried for him. He wanted to say something to Kikimaru but the latter understood him perfectly. 

"Worry not, Master Oetsu. I have everything prepared for you. We will bring you to a bed and have the Med-Scanner check you out. Guys help me here please."

"Sure."

Together they carried Oetsu to a very modern and comfortable hospital bed. The Med-Scanner was fired up and began to do its work. Unlike other times though ... it took very long to get any results. This was understandable due to the amount of changes that had happened to Oetsu. 

Oetsu programmed the Med-Scanner to be up to date with all his projects. The Med-Scanner had all the data of Oetsu's plans and projects and the data of his last scans and could then see the differences and what had changed since his last scan. It was every Pharmaceutical industry's dream. 

After a long 23 minutes, the Med-Scanner finally produced some results. 

|| Status

- Health: 

--> Exhausted, Beyond Peak Health

- Physique: 

--> Modified cells found. Possible reason: new organelles found, stemming from viral descent. Projects: Whitelight Virus + EVO Virus most likely reasons.

--> Cells have been modified. Apart from new organelles, there is a constant change observed. Possible reasons: Doomsday Cells, Primal Zerg Cells, and Gourmet Cells are most likely reasons.

--> Body is in constant change. Evolution and adaptation working as intended.

Soul: 

--> Soul massively strengthened. 

--> Projects: Soru Soru no mi, and Ikomikidomoe are the most likely reason for this change. 

--> Soul is in constant growth at the moment. 

=> Hogyoku functioning as intended. Future growth ... incalculable. 

Suggestion: 

- Rest and nourishment. Project: Gourmet Cells have been fused with the host cell. A lot of nourishment is necessary. ||

"Well ... I think it was a success Master Oetsu. Please allow me to be the first to congratulate you, sir.", Kikimaru said. 

"Thank ... you.", Oetsu managed to say. 

"I will be back with your food, Master Oetsu. Just don't move from this position. I will leave the five here for now. Please excuse me."

"What did you do exactly Oetsu? Did you take some sort of drug to get powerful?"

"Or did you do Hollowification, but better?"

"Guys he can't talk right now. We should wait for him to get better first. But you will have to tell us in detail."

"Haha ... I will. It was not exactly ... Hollowification ... better ...", Oetsu said.

"Better?! Oh, that's sick. I can't wait to see what changed."

"By the way Oetsu ... what's with the tattoo on your back? That's new right?"

.

He was right there was indeed a tattoo on Oetsu's back It was the Eight-Handled Wheel with two wings on the right and left side on top of the wheel. 

It looked like the head of Mahoraga. 

Oetsu knew instinctively that the wheel worked similarly to the wheel from the JJK Mahoraga. It would turn when he was about to adapt or evolve and ... it looked very cool. Normally Oetsu didn't like tattoos but this one ... seemed right to have. 

"How long was I gone?", Oetsu asked them.

"Not long actually... close to two days."

That was about ... 2 years and 8 months. The fusion took over 2.5 years ... Well now Oetsu wanted to see what he gained out of all this. He already felt the Nanomachine activate and show him a lot of things it could do ... This was going to be awesome.
