It's just more like Hypothesis, and I highly doubt that Kishimoto will give another chance to Black Zetsu in “The Last” movie as was given in series. However, I would like to discuss about it.
Here’s my theory:
Ok, I was wondering that White Zetsu is made of Hashirama’s DNA, So Black Zetsu should be made of something, even if Black Zetsu is Kaguya's will, I’m just curious of what is made of I think BZ is made of Truth-Seeking Ball. Pardon me, I'm just assuming, and this is my theory, I have no knowledge of what BZ is made of, I have no proof. It just occurred to me that IT has shape shifting abilities and more, and in this Wiki it was mentioned IT is made of black mass, and I assume probably IT was part of Kaguya's body, so maybe she had given life to her broken part (her Ten-Tails part might had cut off prior to sealing) and the Truth-Seeking Ball (Black chakra, malleable) or possibly Yin chakra merging with her body parts or tailed beast created an entity known as Black Zetsu. This might have happened during the creation of all things. I would encourage if someone came up with different theory.
BZ mentioned itself as Kaguya's child and likes to be attatched to Kaguya as it was seen hiding in her kimono.Not to mention it even opened up new dimension in its last attempt to save his mother, same technique as Kaguya’s. I don’t think that a normal thing could Impale Madara who became Ten-tails Jinchuriki so it is obvious that BZ was made of TSB. Also BZ can shift shape but also likes to remain in humanoid form.
Well I'm confused, I think the Chakra natures' Yin-Yang, Nature energy TSB, Tailed beast, White zetsu are all linked related somehow. You might have already known and discussed about this, but I’m highlighting this in discussion because it’s seems somehow related to BZ and this is for everyone’s opinion.
So the Point of my Discussion-Is Black Zetsu made up of anything like Yin Chakra/Black chakra and White Zetsu Yang Chakra?
I'm suggesting this could lead to something in the future. So we know it is locked in genesis dimension, so it’s not important, but who knows it might come back. Or may be Tonneri was also manipulated by Black Zetsu in some other way we probably don’t know If only the BZ history was clear and this was my guess
Kishimoto stated that he had decided to make Zetsu half black and half white to "better show his split personality". Naruto series always intrigues me that there is always something related and connected, and Black and White Zetsu fusion resembles Yin Yang symbol (as I have always know which is symbol of black and white forming circular pattern).
As Kaguya’s Expansive Truth-Seeking Ball had all Chakra natures and also Black Zetsu’s nature is similar to that, I see no reason why my theory can’t be considered. Correct me If I'm wrong anywhere.
Got it @Elveonora, Thanks for that. I take it that you agree, I have a question considering TSB was affected by natural energy, do you think that black zetsu's reduction in size and parasitic attachment to any host mostly white zetsu and Kaguya had to do anything with that?, because he was seen in full form during the time of Madara's battle, and now we see only half parts, and unlike White zetsu it doesn't grow parts, unless they are merged which probably explains Yin-Yang concept.
You are right about that, I guess Black Zetsu is not a solid mass, because he was ripped off when he was absorbing chakra of Naruto and Sasuke. But that doesn't explain how he impaled Madara, So possible explanation would be that he can control when to be hard solid and when to be a gooey material.
@TricksterKing yup, that could explain it, I see your point why BZ can't be Truth-Seeking Ball, and If I argue that BZ has all chakra nature as Truth-Seeking ball, It would not make sense, it's like comparing Naruto to TSB because Naruto has All Chakra nature types, but we know he's not made of TSB. I guess I was overwhelmed. So BZ is made up of Black Mass, Which is Yin chakra + Ten-tails body part. But I need to confirm it and still make it clear.
Black Zetsu is prolly the physical embodiment of the shinju tree's mind xD
Haha I see where you did there, you thought that because of It's role, I liked it. Yeah, It is related to Shinju,
Black Zetsu had an affinity towards White Zetsu and Obito. Because of Hashirama’s DNA, he used Wood release techniques. When merged with White Zetsu he had plant like projections so it’s probably related to Shinju (or may be Hashirama’s DNA), only by appearance have I considered it. But I don't think wood release is related to Ten-Tail's since It's not mentioned, but It should have it since it is a tree. Man Black Zetsu is a puzzle, the more deep I go into it, I lose my mind.
^^ I'd say it's still possible that he's a TSB, he was able to use any techniques of the bodies that he attached himself to without any trouble, him being able to be cut in half could be explained as him being unable to use yin-yang or not bothering to prevent damage since he can just reform himself.
Also Naruto's Sage upgrade allowed him to resist Zetsu's chakra absorbing while Sasuke was helpless and later allowed him to throw Zetsu into the moon without Zetsu becoming goo and escaping.
@Trickster Thanks for that, you explained very well, I felt like I was going nowhere, I was not sure how to explain, which lead me to believe that It was not TSB for a while, I forgot then I re-read, phew, Ok, so that explains the TSB part. He may be using Yin-Yang release as he wishes, there is a limit to his malleability, he can reform but he lost some parts when he was fighting with Naruto and Sasuke.
I think Black Zetsu is a link between TSB and Chakra receiver rod, So I’m making another theory He was seen with Black rods when he was taking control of Obito, After that he did make Shakujo with the Black Zetsu after gaining control back Impaling Madara to get Kurama and Hachibi, He deflected Madara’s TSB. TSB is malleable and it can shape shift into rods just like Naruto and Madara had, but the Chakra Manifestation rods are solid constructs, another difference is distance; The rods absorb chakra, and are used to immobilise someone and doesn’t require user to be near, but it doesn’t affect anyone who has six paths sage chakra (not just sage), and TSB can only be used by the user upto 70 m of distance. They have only one similarity they negate Ninjitsu, not to mention they came from the Statue Gedo Mazou you know the Rods came from Statue’s navel and TSB came from Ten-tails (when Madara was going to attack Guy but Naruto kicked it), I think the rods can be used by anyone with Rinnengan like Nagato, and TSB who has become Ten-Tail’s Jinchuriki, and who has SPSC, & rather unusual case Kaguya’s KKM. And I think Rods are made up of Yang Chakra (+ some other chakras, they are product from Gedo Mazou – 9 Bijuu and I read somewhere it was made of Hashirama’s cells), so they are absorbing Yin chakra from body to immobilize and disrupt flow of chakra path. Obito’s usage of TSB is like that of Gaara using Sand, I believe this malleability is because Obito is infusing Yin Chakra, and I believe that Black zetsu’s use is similar Yang to Harden and Yin to become malleable(vice versa is possible).
Apart from their elemental chakra I would like to highlight the similarity between Truth-Seeking ball and Ten-Tails i.e. they don’t have Wood release.
I think this will be enough for explanation.
Wood release is related to Yang chakra (plus it needs Hashirama ‘s cells, probably the only physical thing), Naruto possessed Yang Kurama, and made the wood grow, so I would relate White Zetsu made up of Yang chakra because they show same effect to Yang Chakra, so it seems like they absorb Yang. So Black Zetsu being able to absorb Yin Kurama, I would relate it to having Yin Chakra. I also began wondering why Yin-Half was being sealed in Minato for DD consuming seal but not Yang half; So Yin is for Spiritual and Yang for Physical and Vitality. When merged and molded become chakra itself. So yin,yang basically in parts alone are chakra. If they are disturbed by Natural energy, overpowered by that then they become toad, degenerated, and latter happened to TSB, I have so many questions, but I do relate my answer to sage chakra like I don't know why there is some similarity between Obito and Kabuto’s appearance after gaining some sage chakra, like the scaly version?
yeah, but it's like living thing, will materialisation may be just a name because BZ tricked Madara into thinking that he will work for him and saying that "I am your will" like I'm your wish or something, but ultimately BZ turned against him and said all this time he was using him and planning for Kaguya's revival (saying I was Kaguya's will). And here in wiki it is mentioned as a technique, I'm not sure that the black rods from zetsu are his own or was it the seal obito had on his heart? I think BZ was doing on his own, upon receiving signal from Madara by chakra receiver rod, BZ then took control of Obito's body in Chapter 656, last page I think that was to restrict Obito's movement. In Chapter 665, last page after Obito gains control, Black Zetsu was unable to detach from Obito, then Obito was wielding Shakujo formed by Black zetsu's gooey body, which is just like that Obito used to have, he controlled Black Zetsu, indicating that BZ is made of TSB. Will is just a word BZ used, to ascertain the completion of Tsukiyomi, that's what I think (like will = wish to be fulfilled after death).
But we can't argue on it as it was also related to Gaara's mother Karura, after her death her soul controlled his sands for defence. I can't understand this one, I think at that moment Gaara used his imagination, maybe I should watch that episode again.
