Board Thread:Theories and Speculation/@comment-5413572-20150113034236

I started another thread dealing with this same subject matter, but this one will be a tad more specific. As before, this is all fanfiction that contradicts the official canon, so keep that firmly in mind. Criticism and feedback is more than welcome, but please treat this for what it is.

Anyway, as I addressed in the other thread, I didn't like how Kishimoto handled the origins and descent of the Great Dojutsu, and began contemplating my own alternative, which goes like so:

Kaguya, after eating the Shinju's Chakra Fruit, awakened what I call the "Gōkeigan" (meanng "total eye"), which possesses the powers of all the subsequent Great Dojutsu. When she gave birth to Hagaromo and Hamura, the Gōkeigan's power was split evenly between them, with the former getting the (six-tomoe'd) Rinnegan and the latter getting the Tenseigan. The Rinnegan then diluted to the Sharingan in Indra, while the Tenseigan diluted to the Byakugan in the Hyuga. Recombining Asura's and Indra's chakras replicates Hagaromo's, thus allowing one to awaken the Rinnegan; while recombining the chakras of the Hyuga and Otsutsuki clans would replicate Hamura's chakra, allowing one to awaken the Tenseigan. And hypothetically, if one were to awaken or otherwise acquire these two dojutsu, they'd awaken the Gōkeigan. In short:

Gōkeigan = Rinnegan + Tenseigan Rinnegan = Indra (Sharingan) + Asura Tenseigan = Hyuga (Byakugan) + Otsutsuki

However, this also got me thinking about how Kishimoto handled the Tenseigan. Now, I have yet to actually watch The Last all the way through and haven't read its companion book, either, so I'm going purely off what this wiki says; however, the latter indicates that the Tenseigan, despite supposedly being as powerful as the Rinnegan, basically gives Toneri an equivalent of Nine-Tails Chakra Mode with Truth-Seeking Balls. This seems rather pathetic to me- the Rinnegan gives the wielder access to a treasure trove of unique and versatile techniques, up to and including the ability to freely manipulate life and death and the ultimate fuinjutsu- so shouldn't a dojutsu of supposedly equal power be capable of comparable feats? Granted, Toneri did cut the moon in half, but even if we assume that no other character could do this (and I find that dubious, especially if he's only on par with Nine-Tails Chakra Mode), it still seems like a pretty bland capability after everything we saw the Rinnegan (and even the Sharingan) do prior. So, I came up with this alternative.

Kaguya, having had the Gōkeigan and later being fused to the Shinju, could freely access Yin-Yang Release and Natural Energy. When her power split between her sons, Hagaromo got the Rinnegan, which also gave him access to Yin-Yang Release. It would follow, then, that the Tenseigan would deal more with Natural Energy. Now, of course, any sufficiently skilled ninja can use Natural Energy via Sage Mode, but it's imperfect, temporary, risky, and is basically just a power-up for regular ninjutsu, as the chakra of those using it is still primarily Yin-Yang-based. Those with the Tenseigan, however, gain access to chakra based purely on Natural Energy. Like the Ten-Tails, this gives them virtually infinite chakra and renders them virtually immune to being sensed, as well as endows them with the heightened durability, stamina, speed, and strength of Sage Mode, but to a far greater degree. Where Sage Mode also involves taking in Natural Energy to augment the user's own chakra, the Tenseigan instead confers one with an ability similar to Amenominaka- the user's own chakra leaves their body and merges with the planet's Natural Energy, allowing one to instantly alter the landscape and even the atmosphere across a given radius by manipulating the Natural Energy in the area. However, as with Amenominaka (and similarly to Sasuke's Rinnegan), prolonged usage of this technique strains the user's eyes, forcibly returning them to their body and deactivating their Tenseigan for a limited "cooldown" period. Because of its relation to the Byakugan, the Tenseigan would also allow one to see the planet's "pressure points" (i.e. the tectonic plates, mantle, groundwater, etc.) and freely stimulate them via the remote manipulation of Natural Energy, allowing for the creation of different natural disasters. The Truth-Seeking Balls conferred by the Tenseigan would also be based more on Natural Energy, and so just as conventional T.S.B.'s are vulnerable to senjutsu, these would be vulnerable to powerful Yin-Yang Release techniques.

Thoughts?
