Body revival

Misconception about body revival is that it needs dark chakra. This is not the case. Dark chakra merely amplifies the jutsus effects.

It's main function is similar to a saiyans zenkai. As the wiki states:

" The principles of this technique is to take advantage of the muscles' ability to grow stronger after repairing itself from damage. Understanding this theory, the Body Revival Technique can repair the user's body and increase its strength by manipulating the "Destruction and Rebirth" cycle of the muscles

This technique allows the user to survive any otherwise normally fatal damage and instantly heal from the damage. A unique trait of this technique is that it can momentarily give the user the appearance of death, fooling even the most talented medical-nins.

When combined with Dark Chakra, this technique can also be used to physically enhance the person's speed, strength and healing capabilities to superhuman levels."

This is a medical ninjutsu. Ren with the Byakugan and his medical training should not have a problem recreating the technique. Especially when he's specifically aiming to create it. As for the dark chakra, keyword here is WHEN combined. It's not necessary.

Seven heavens breathing

Wiki definition:

" A taijutsu breathing method that Shira invented by gathering up large amounts of oxygen to increase his lung capacity fourfold, he is granted strength similar to the Eight Gates, even including similar physical changes to the user.

Much like the Eight Gates, this technique has several stages or "activations":

The first activation causes Shira's eyes to go completely white and he starts to give off a yellow aura.

The second activation causes his body to expand slightly, his muscles becoming distinctly more prominent.

The third activation causes his skin to go red and appears roughly equivalent to the Gate of Life. "

Since the concept of seven heavens breathing reflects the concepts of the Eight Gates it's likely similar in theory and application. Note Shira has fourfold lung capacity and three activations created. Most likely lung capacity dictates the amount of breath activations. Like the eight Gates the breathing method is likely to channel massive amounts of chakra and let it course through the body. Ie the additional oxygen from increased lung capacity converts into chakra overwhelming the tenketsu like Eight Gates does by removing limiters. This technique should have detrimental effects similar to Eight Gates, it's likely on a lower level though or it would be eight breaths. Most likely safe to use to the third breath with sufficient training.

Similar to body revival it shouldn't be too hard for Ren to recreate the technique with the sole knowledge of knowing it relies on lung capacity. Combine that with his medical expertise, knowledge of the Eight Gates, and the Byakugan to monitor the tenketsu. Self creating this technique logically should be simple for him.

Eight Gates

Wiki:

" The Eight Gates exist in order to limit the flow of chakra within an individual's body. Ordinarily, individuals can use no more than 20% of their body's full potential, the brain's way of protecting the individual from harming their body through overexertion. With training, individuals can learn to remove these limiters, referred to as "opening" the gates. With each opened gate, individuals are given access to more and more of their body's chakra, thus increasing their physical strength and speed. "

The most impressive part of the Eight Gates is complete body control by removing the brain limiter. Ie when Kakashi used it to force his single hand mountain climbing. It also likely helps you not destroy tour tenketsu when opening further Gates and regulates the chakra so the ever increasing reserve doesn't either.

While it's supposed to be detrimental it's actually fairly safe to use up to the third gate. Lee can actually use the first gate with no drawbacks and by the fight with Shira can leave the third gate state easily with no damage.

Now let's talk about the combination of these three techniques. The Saiyan transformations. Why call the combination saiyan transformations?

By imbuing body revival into the strength of a hundred seal the technique should operate passively for Ren. Which means the more damage he takes the stronger his body becomes. Essentially giving him the saiyans innate ability of Zenkai. Combining this with seven breaths would give one a golden saiyan aura look, then further combining it with Eight Gates it would give you a green Broly aura look.

The use of basically two Gates of life should also compound onto Rens body damaging it but due to the body revival technique and the gate of life's traits also massively improve the body's healing and overall physical abilities. With the physical improvements being permanent on the body revival portion. This definitely does not reach the body revival techniques might when combined with dark chakra but definitely a tier or two below.

It's likely the only suitable replacement for dark chakra is Kuramas chakra or something on a similar power scale.

Hydrification technique

" This jutsu, a hallmark of the Hōzuki clan, allows the user to liquefy any part of their body at will, from the hair on their head to the muscles in their arms."

Hydrification has a lot of perks but the main ones I like come from Suigetsus info on Hydrification.

" As a member of the Hōzuki clan, Suigetsu is well-versed in the clan's secret Water Release technique to transform his body into a liquid form, and to return to his solid bodily form at will. This gives him a higher level of control for his various Water Release techniques, able to perform them without hand signs."

Without hand signs! Now how is this technique acquired by Ren? I say Tobirama likely researched it. As a water release master that can generate his own water for his water jutsu it seems implausible he didn't look into it.

If that's not satisfactory I feel converting ones cells to liquid shouldn't be hard for the Hyuga as releasing chakra from all your tenketsu likely makes the conversion process easier. Not to mention it's likely a derived combination of water release and transformation jutsu. Combine all that with medical ninjutsu knowledge and it shouldn't be impossible for Ren to self create the technique either.

Main point:

Overall with sufficient medical knowledge and the Byakugan self creating techniques shouldn't be too hard particularly the ones I highlight as they all have to do with Rens physical self. This is why the medical info dump I made was key to the story. It's really the base for all his techniques and the Byakugan either facilitates or compliments the techniques use or creation.

Due to cutting back on info dumps I started skimming over how Ren would create/ acquire his techniques. Would you guys prefer I stop that? There's been a lot of comments criticizing he gets crazy shit out of nowhere. Clearly there's a method to my madness though.

Everything is methodically planned to the realm of plausibility. It's the main reason I don't just go he self created chimera technique fear and rejoice! Like no. It's not something I would do.

For example going back to the Hydrification technique in particular. Like why would Tobirama have that?

Well when Madara threatens Mu and Onoki to serve Konoha it is after the first Kage summit and it's implied Mu is the current tsuchikage at that point. Mu notoriously has a feud with Gengetsu Hozuki the mizukage, so leading up to the first ninja war both are active kage. It is only natural Tobirama would gather knowledge on the island nation to the east of Konoha and learn more on its Mizukage. Especially one that has a unique water technique in which he himself specializes in. Unless Tobirama's an idiot there's no way he didn't research this. We've never been given reason to believe he's an idiot so here we are.

So why is gengetsu still alive in my fic? And by extension Mu? Well Onoki. He was only kage during the third shinobi war. Implying Mu and gengetsu didn't meet their mutual death until after the second war.

I hope this lets you guys in on my process. Again everything is methodically thought out to avoid plot holes. I just figured info dumping on how and why he can create the techniques is more reminiscent of the first few chapters I wrote which honestly are a little tedious to read even for me.
