1) Kaguya Otsutsuki In the final act of the series, the seal is broken as the Ten-Tails reappears and so does she. Kaguya has access to all, including Kekkei Genkai like the Byakugan and Rinne Sharingan. Combined with her tailed beast transformation, she is most definitely the most powerful entity in the Naruto series.
Who are the gods in Naruto? Jashin is a god whose presence has little to no origins. He was first introduced by Hidan in Naruto Shippuden, and was the source of his immortality. According to Hidan, Jashin's ideologies center around violence and blood sacrifice.
Naruto Uzumaki
By the end, Naruto is the most powerful shinobi on the planet. In his basic human form he can create countless shadow clones, summon giant toads, and wield the awesome Rasengan. Then there's his Toad Sage mode, where he summons nature chakra to make him more powerful than nearly any other shinobi.
Jiraiya. Jiraiya was an exceptionally competent shinobi, and he was the only member of the Legendary Sannin who could actually beat Itachi. He was trained by the Third Hokage, and learned how to use Sage Mode while training with the toads of Mount Myoboku.
Who is the god of Uchiha? Indra Otsutsuki is revealed to be the creator/ founder of the renowned Uchiha Clan in Naruto. He was the eldest son of Hagoromo Otsutsuki (The Sage of Six Paths) and the elder brother of Ashura Otsutsuki.
In Boruto, however, fans witnessed Kurama's death and the questions rose up once again as to whether Naruto can win against Sasuke without him. To the fandom it seems that, although it would be extremely difficult, it is not impossible, and at worst the fight might result in a draw.
Shibai is the strongest of all the Otsutsuki and here is what fans need to know about him. The world of Boruto has seen the introduction of several powerful gods of the Otsutsuki lineage over the years.
He is dubbed by most to be the strongest shinobi in history. Sasuke himself admitted this fact. In the end, while Sasuke may not be able to beat Naruto, even with his perceived weakened state in Boruto, the two did become friends again. A combination of powers that are said to be able to destroy the entire world.
Sasuke was stated to be the strongest Uchiha to ever have been born, including Madara. So, obviously, his powers do exceed Madara's. With his Choku-tomou Rinnegan and Indra's arrow, he is almost invincible. As a result, he is also one of the Naruto characters who can defeat Madara.
Black Zetsu was central to one of the biggest shocks in Naruto during the 4th Great Ninja War. It was he who stabbed Madara Uchiha in the back and struck him down when he was at the pinnacle of his powers. Zetsu was then revealed to be the perpetrator of the plan to bring Kaguya back.
1 Baryon Mode
Baryon Mode powered Naruto Uzumaki up to great levels, and made him strong enough to overpower Isshiki Otsutsuki in battle. This transformation made him the strongest character in the story, and is Naruto's strongest form by far.
2) Naruto. It's safe to assume that Naruto surpassed Kakashi during the Pain arc. He was able to defeat Pain and later he was able to use Sage mode as well. His ability to link up with Kurama and his vast chakra reserve make him an incredibly powerful shinobi.
9 Naruto Vs.
While Sasuke did extremely well against Gaara, he wasn't able to defeat him. In the end, it was none other than Naruto who, using his clever strategies and the Nine-Tails chakra, was able to take on Gaara and defeat him in an all-out battle.
The death of Kurama was one of the saddest things a Naruto fan has watched during the course of the series. The Baryon Mode killed the Nine Tailed Beast, who not only assisted the protagonist in battles, but also happened to be one of his closest friends.
Obito Uchiha was one of the strongest Uchiha to ever exist. He awakened his Mangekyō Sharingan during the Third Great Ninja War after witnessing Rin die. Obito's eye weilded the Kamui, a powerful space-time ninjutsu.
6 Shin Uchiha
He was one of Orochimaru's experiments that ultimately went rogue. Shin was given several Sharingan Eyes (much like Danzo) and even managed to awaken his Mangekyou. He had plans to resurrect the Akatsuki and was confronted by Naruto Uzumaki and Sasuke Uchiha in Boruto.
Madara was great during his youth, able to keep up with Hashirama Senju (The First Hokage) and do major damage with his Susanoo. At the height of his power, he was able to slaughter entire groups of ninja, take on the Kage, and slice the tops of mountains off! Alone, Boruto wouldn't stand much of a chance.
Shibai Otsutsuki is, by far, the strongest character to ever appear in the story and, for him, dealing with someone as strong as Naruto wouldn't be an issue at all. Even if Naruto had not lost Kurama, his powers would still be inferior to Shibai Otsutsuki.
Naruto and Sasuke are arguably the most powerful characters by the end of the Naruto Shippuden anime, so it goes without saying that Might Guy would stand no chance against Naruto in his Sage of Six Paths mode, or against Sasuke using his Rinnegan.
