*It's unknown, though presumed Hashirama died in the first war due to being weakened by his fight with Madara or possibly passing away shortly after the fight due to exhausting his life force with mokuton.
*We'll have to wait for the movie or the series, but from what I hear, Kishimoto stated in an interview that he'd probably never show it. Probablu out of fear of backlash or simply to keep Kakashi immortally charismatic and mysterious.
*Unknown, though I made a theory Madara once had Amaterasu and Tsukuyomi but used the yin yang release of the rinnegan to permanently fuse them and create the Limbo technique.
*I believe he stated he gave him the last of his chakra.
*Some believe Kishimoto may have retconned Hagoromo's tools, given how much emphasis was put on them and Madara's horn falling on them, though it is shown later that Ten Ten helps Darui to release Samui and her brother from the gourd somehow using some sort of scroll.
*I would imagine they were her palaces where she lived since she created the dimensions, though I suppose it's also possible that's where the Ootsutsuki clan may have originally lived.
*There's a translation for it now and I believe he used it on Obito where he was bloating up from the juubi being inside him.
*It's heavily implied Orochimaru was jealous of Minato being appointed Hokage and hated Hiruzen for it. Orochimaru also found deep corruption in the leaf through Danzou and wished to obtain immortality out of fear of death and the loss of his parents and Tsunade's brother. However, he became twisted. There may be another reason, but if there is, it's unknown.
*=possible movie spoilers= It seems to be implied that she planned on fighting the Ootsutsuki clan stationed on the moon who were introduced in the databook and will make their appearance in the final film.
*Madara originally implied she meant to end conflict and bring peace, but the databook states she came from another planet and coveted the fruit. Naruto also stated she was heartless. This could mean she was either a power hungry, evil conqueror, or the shinju took her over. Not even Hagoromo was sure.
*She mistook them for for her sons because they were so similar. It could imply Hagoromo and his brother were rivals as well with similar chakras and powers. They also resembled Naruto and Sasuke to an extent. This was also how Hamura's name was introduced.
*It is unknown if he is still alive, but the databook stated he migrated to the moon with the remains of the Ootsutsuki clan and kept watch over the gedo mazou there. =spoiler=Toneri, a member of the clan with the byakugan will appear in the film as a supposed antagonist.
*The Senjus are implied to be either killed off or their bloodlines lost through mating with other clans in Konoha. But nothing is certain.
*His all time goal from what I remember was becoming immortal and being able to control life and death.
*I don't understand this question.
*Kakashi did copy a thousand jutsu, but most are probably meager and weren't powerful enough for the war. Furthermore, he did not have enough airtime to show anywhere near this many techniques. The plot steered away from him several times throughout the series as well.
*I believe he does. He worked hard for it, saved the world and the alliance and kept their morale going, befriended, tamed and freed the bijuus from oppression who were major catalysts to conflict and as Hokage has kept the five villages allied with each other so far. It would appear he is using both his own principles in conjunction with those of the previous kages and his senseis. A great balance.
*It is unknown. He may have killed a friend or rival in mortal combat, or he may not have. Itachi and Sasuke unlocked mangekyou without killing their friends. It's implied Itachi just said that to Sasuke to make him angrier and to test how how good he was.
*The pain of his best friend was enough to unlock it rather than killing him. Same as when Sasuke unlocked his after learning the truth about Itachi.
*Unknown. It seems when he was young he traveled across the country and studied texts in ruins based on Hiruzen's backstory about him. Perhaps he found them that way, or perhaps something special about his chakra summoned them.
*I don't believe they were merged. The susano'o just held them.
*Unknown. Maybe he did but just doesn't want to use them, or can't because he doesn't have the right chakra to summon or use them. To little info about the weapons is known to speculate
*It was implied half of Konoha shinobi at the time were under Danzou's control through root, and had Hiruzen tried to arrest or attack him, it may have caused a civil war.
*My theory is he resonated with both his eyes, which were in the vicinity at the time, using the gedo rods in his body. This was also how he restrained Hashirama just before.
*My theory is he either used the senju flesh and chakra he had digested a bit to cast it, or had another Uchiha or possibly used another eye himself with senju dna and chakra to implant it, since Black Zetsu made reference to Itachi implanting the timed amaterasu in Sasuke's eye. There also is no evidence that Madara didn't already have senju DNA infused in him, especially considering Itachi stated countless Uchiha and Madara fought numerous Senju throughout his life.
*He had only one eye for almost all of part 2, and when he finally got both back in the kaguya arc, he was low on chakra and conserving it in order to use kamui to help Naruto and Sasuke.
*Obito was once the sage of the six paths from absorbing the juubi, possessing the rinnegan and using rinne tensei. He temporarily merged his chakra with Kakashi afterward, and this allowed Kakashi to use perfect susano'o like Madara and Sasuke. Kakashi also stated the six paths power had greatly upgraded him as well afterward.
*As I said, he once personified the sage and used his rinne tensei and onmyouton. He also learned hagoromo's techniques from Madara it would seem.
*Because Madara had unlocked his chakra and spirit by obtaining the Rinnegan and absorbing the bijuus.
*Onmyouton most likely which can manipulate life, death and reality and cancel or erase active jutsus.
*Sakura mostly loved him for his looks at first, but afterward, she actually learned more about his tragic history and lonely life. This was implied by Kakashi after Naruto restored his eye.
*The Uzumakis were killed off in an unknown war by an unknown country. The ones that survived became refugees including Nagato and Karin.
*It was implied to be a very rare kekkei genki, much like mokuton.
*Hashirama was Ashura's reincarnation and the shinju appears to personify the god that created the land, life and senjutsu, which mokuton also seems to personify or at least be a degraded branch of. Ashura and his transmigrants inherit the Hagoromo's physical chakra and senjutsu.
*Unknown. It effects mokuton massively and doesn't appear to resemble snakes or toads so perhaps it's some sort of forest or ent senjutsu.
*Most likely he read it from Hashirama's scroll, where the compilation of the senju and all the konoha clans' jutsus are documented, paralleling the time Naruto learned the shadow clone jutsu from it.
*Minato stated he was not skilled in senjutsu and it would neither last nor be of much help.
*Unknown. He may have been releasing Hashirama from the gedo rods. There wasn't anything he could do because Madara had already avoided his FTG and demolished him, even without the juubi in him.
*Yin Kurama was sealed in Minato by the shinigami of the shiki fujin and they were trapped within its stomach for seventeen years. Hiruzen stated in his battle with Orochimaru that the one who casts the shiki fujin will do battle with the enemy he seals with himself inside the shinigami's stomach for all eternity. This means Minato had the time to harmonize with Yin Kurama.
*Answered above
*That's an anime, not a manga question lols. The anime often makes canonical mistakes in animation. They made Kurama breath fire in the pain arc and it really ticked kishimoto off lol.
*Unknown, though both white and black zetsu, as well as the gedo mazou, which Madara was attached to could travel unprecedented distances through the ground.
*Some said they were going back to their homelands while Gyuuki said he would stay with Bee, which he did.
*It was implied to me that she eating the fruit manifested them, sort of like messiahs.
*They weren't? I don't know what you mean. Perhaps during the fight when Kakashi saved her a few times as well as they sitting on the sidelines during the battle with Kaguya?
*No, Naruto cannot resurrect people. What he did with Kakashi was restore a piece of him that was lost and kept Gai's life force going by powering his heart. Neji is dead and his soul has passed on into the afterlife. The only ways to resurrect him now would be through the use of rinne tensei, which sasuke probably has but cannot use on account that it either kills the user or greatly reduces their life span. And being that Sasuke is an Uchiha and not an Uzumaki with a large physical life force, it would probably be the former for him.
*On his quest across the world to find the answer to peace, Jiraiya encountered these people who shared their personalities, occupations and ideals of peace with him. One was a religious man who was spreading his faith and Pein made him the avatar of the Naraka path, which summons the King of Hell or the afterlife, Yama. Another had established a military school in order to teach people self defense, tranquility and peaceful relations, somewhat like a Xaolin monk. This man became the avatar of the human path. Based on this, it seemed to imply each of these people's chakras possessed a certain compatibility with one of the six paths.
*He stated before Kaguya was completely sealed, she pieced a small portion of herself out with her will attached to it and it became him.
*Because the war was over and they belonged in the afterlife.
*I believe a colored cover page showed Sasuke destroying it as he left to head out to the war. White Zetsu also stated he destroyed the original white Zetsu stationed there when Sasuke came on to the battlefield and unleashed his susano'o on all the zetsus.
*Unknown. They come off as being part of a primal clan not far off descended from the Oostutsukis somehow, like Kimimaro and the Kaguya clan, as well as Juugo's unknown clan.
*Hagoromo seemed to believe the fruit corrupted her mind and heart and gave her a god complex.
*She was Orochimaru's student and a flashback of the two was shown just before Sasuke sealed Orochimaru.
*I don't believe he existed and that they were sired by Kaguya and the Shinju's fruit.
*Unknown. He may not have even unlocked the mangekyou.
*It implied to me that while they were gone, Sasuke's use of the eye's powers were active.
*Unknown. Probably during his three years with Orochimaru or shortly after he sealed him and formed taka.
*That was just the hawk's design.
*Sakura and K11's development were cut short in part two, most likely to put heavy focus on Naruto's and Sasuke's development. She may show or learn some in the film though.
*Unknown. He may be in the final film or he may not be.
*True.
*Until now, Byakugan has been shown to manifest in the hyuuga from birth. It may be dormant, it may be recessive, or they may manifest a completely new doujutsu due to their mixed uzumaki and hyuuga lineage.
*Naruto I believe is the only one of the two confirmed to have a hashirama clone's arm. Furthermore, he is Ashura and Hashirama's reincarnation and obtained Hagoromo's senjutsu, so yes, I'd say it's a strong possibility he has mokuton now. I don't know about the kids, but Hashirama was stated to be the only senju in history to unlock it, which means his children did not. Sasuke I doubt it since he doesn't appear to have Hashirama's DNA attached to him.
*Unknown
*Technology appears to have thrive in the timeskip, probably because they had more time to develop it rather than spending their times fighting wars and going on missions.
*It looked to have crumbled when Kaguya took him over.
*Probably because everyone wanted to see Kakashi and Naruto as Hokage lols. She also seemed to question her role as Hokage being that she dreamed in the Infinite Tsukuyomi that Dan survived and became Hokage. Sakura also stated she was busy developing Hashirama's clone arm for Naruto.
*Because he's the most revered Shinobi in the village. He was almost made Hokage before Danzou ursurped the position.
*Considering they were about to be killed and remade into white zetsu drones, probably not.
*Unknown. Perhaps it really was just his imagination or perhaps it was Karin or a foreshadowing for the movie. Possibly Toneri.
*Kakashi is getting another backstory in a novel and I believe in the upcoming mini series. They may show Sakumo's abilities then.
*Naruto probably had the elder house remove them since he promised Neji he would change the hyuuga clan if he became hokage. Or Hiashi may simply have just removed them himself after the war or stopped the use of them.
*For Itachi, probably to see all his abilities, mystic weapons and figure out if he was scheming something against him, which in the end, he did with amaterasu implanted into his eye. With Pain, he probably wasn't sure if Jiraiya would lose to him or if he would succeed in convincing him to stop.
*That was a mistranslation. He stated he couldn't phase through things. He didn't state he couldn't use Kamui period, or travel to its dimension.
*Sasuke obtained his Rinnegan in a different fashion than Madara and Hagoromo. Hagoromo was born with his through Kaguya's genes, and Madara infused himself with Hashirama's flesh and chakra. Sasuke obtained all of Hagoromo's Yin chakra straight from Hagoromo himself. My theory also included the six tomoes remaining to either condense the six paths into one eye rather than requiring two to use them, as well as keeping all of Sasuke's mangekyou techniques intact. This theory branches from my belief that Madara could no longer use his mangekyou abilities save for his Susano'o on account that the Rinnegan may have either mutated them into the Limbo technique or Madara may have manually and permanently fused them to create Limbo using the Yin-Yang release of the Rinnegan. Kaguya's eye was never directly called the Rinnegan. Hagoromo referred to it as the Sharingan, it used Tsukuyomi and Sasuke stated Kaguya used a rinnegan doujutsu, not a actual Rinnegan. Based on Hagoromo mentioning the Byakugan with her nine tomoe eye or sharingan as he explained her power she used on the people, I believe the Infinite Tsukuyomi is actually comprised of a mix of both the nine tomoe eye or sharingan and the byakugan. Everyone having rippled eyes like Hagoromo, who is implied to have obtained the Rinnegan through the mixture of both of Kaguya's eyes also supports this. If their canon color is red, it would further support this. On then other hand, whenever Sasuke used his Rinnegan, the tomoes would disappear. This may also support why the victims had none.
*He didn't feel it, he saw it. I would imagine it means it makes them one of a king among all the mangekyou useers, that they possess the same to similar chakras and potential, and in the end, Sasuke is his reincarnation.
*The eight gates may be an old jutsu Madara witnessed before or just knew about since he founded the village with Hashirama and probably knew all of the leaf's jutsus.
*It is the symbol of Ninshuu, his religion and technique teachings. However, I also believe it was a seal to keep the third eye from manifesting and corrupting his mind and heart like it did Kaguya.
*Kaguya according to Black Zetsu became part of the shinju/juubi after she ate the fruit. In other words, she was the juubi/shinju the whole time and Hagoromo and Hamura did not realize this.
*Probably either odama rasengan or his kyuubi cloak.
*Unknown
*Unknown lols.
