(Orochimaru pov)

  After I was effectively chased out of the hidden leaf I was furious. How could I not be? Over the course of two great wars and many more battles I had bled and killed for the vilge loyally and I assed up for Hokage by a brat I had watched grow up. Then they dared accuse me of being a traitor and scum for using the dregs of the vilge in my experiments. My sensei was easily the worst though as he didn't even have the heart to kill me himself a me go, he'd e tret that.-

  Thankfully I had the fht to prepare in case something like this happened and had a base squirreled away in the nd of rice. Annoyingly my other bases had been systematically exposed by that fool Jiraiya who was insistent on capturihe loss of them stung but was something I could accept as money was easy to acquire for me. A few years went by and my experiments had allowed me to discover a way to extend my life indefinitely. I had taken inspiration from the forbidden jutsu [Impure world reination] to create a way for me to take possession of someone elses body by using my soul.-

  There was a slight downside in the form of myself now being uniquely vulnerable to genjutsu but I had a pn to rectify this problem as well. inally I was going to kidnap some random Uchiha to possess but after the massacre they were in short supply. Still though both of the optio were tantalizingly talented and one even had the legendary Mangekyou sharingan, the same eyes supposedly as Madara himself! I even subordinated myself to the rogue anization Akatsuki in an attempt to possess Itachi but he overpowered me easily with his powerful genjutsu.-

  With that option effectively cut off from me I iurned my attention back to Konoha were the st Uchiha in the vilge remained, Sasuke. That was not the only child in that vilge that ied me however as there was ahat would have been my perfect vessel due to his talent in any other circumstance, Kenzo Mizuyama. The boy rodigy easily on par with myself or eveer from what my subordinate in the leaf told me. A strange unexpinable and over animals, a supremely durable body with extraordinary strength and flexibility.-

  Godly chakra trol and intellige was all the things I could have possibly asked for in a host with the single exception that the boys body didn't have a whiff of any bloodli all. All of these gifts were there innately without any expinable reason and as a stist this bothered me greatly. Oh how I wanted nothing more than to snatch up the boy and disected him to learn all of his bodies secrets. That would be wasteful however and I was many things but that was not one of them.-

  Instead I left the child to his own devices until I could discover a way to fuse a bloodlio his body safely. I had samples of a vast variety of bloodlihat I had collected during these years that I wao create the perfebination of to create a vessel truly able to achieve my ambition of mastering every jutsu and living forever. Uchiha Sasuke would be a temporary vessel until I succeeded in transf Kenzo Mizuyamas body into the perfect vessel. The sharingan were peerless dojutsu without a doubt but if I succeeded in fusing the bloodlines I had chosen and merging the result into the boys body I could have it and so much more.-

  Time has passed since I left the Akatsuki a my sights on the youth of Konoha and I had a few things to note during this period. First was that I had heavily uimated the difficulty of fusing bloodliogether much less merging them into another's body successfully. I had been attempting to fuse the genes of the dojutsu s of the world that I had samples from together with mixed results despite their shared ary.-

  Yes that had been quite the surprise for me to actally discover, somewhere in the far flung past ead every with a dojutsu had a single aor that gave them their visual prowess. The fragments of that aeics were far too hazy after all this time for me to sequenfortunately but it gave me a point that I could use to initiate fusioween each of these branches of this distantly reted family tree. The Uchiha, oike and Hyuga s geifortunately all shared a trait, they were all dominant.-

  If one were recessive i could probably use that to fuse them together slowly but as they were all dominant any attempt at fusion teo result iic cshes that served no purpose beyond crippling or killing the host I ied with them. Even when I tried to cultivate a geic e the result was always malformed , typically around the eyes i noted, or unviable. Fusing a single bloodlio a non-bloodline host ossible however as I had even successfully awakened a sharingan in one of my subjects who underwent the experiment. Though It should be hat the eye was blue rather than red when activated due to a mutation in the process.-

  My attempts to fuse the oike and Hyuga bloodlines into hosts yielded simir results in the cases that succeeded. For the oike s Ketsuryugan the normally red eyes with purple horizontal goat like pupils were instead blue with red pupils. The Byakugan of the Hyuga were instead bck as if the pupiless eyes had suddenly bee nothing but pupil with no iris at all. The prowess each of these proto-dojutsu was less impressive than the normal thing however which was uable and as such I refused to make more such shinobi.-

  I was still determio fuse these dojutsu bloodliogether but I had that relegated to a side project si was clear it would take some time to make progress. Moving on I found that I had also uimated the boys talent as my sensei had pced the child under my old teammate to learn, Oh did he learn. My spies reported extraordinary growth in the boy as he rapidly mastered iryonin jutsu and refined his own self created taijutsu under my old teammate. With little more than a year the boy even mao create a solid e teique that had me salivating.-

  I took great pleasure in knowing that the boy refused to simply hand it over to my sehe boy instead merely wrote down the requirements to leareique and the risks involved in attempting to. I admit that even I was leery of learning the teique after reading what was written from one of my spies in the vilge. The price for failure was high, VERY high. The teique also had clear fws that greatly lessened my desire to learn it as splitting my focus in such a way was likely to ruin much work rather than help.
