Momoshiki is one of the alien Otsutsuki clan members who served as the main antagonist of Boruto: Naruto the Movie and Boruto: Naruto Next Generations. Being an Otsutsuki, Momoshiki went from planet to planet in search of chakra.
Over time, Momoshiki gained so much strength that he became one of the strongest characters in the entire series, strong enough to fight both Naruto Uzumaki and Sasuke Uchiha together. Strong as he is, there are quite a few characters who surpass him in terms of power. Here are 5 Naruto characters stronger than Momoshiki Otsutsuki and 5 that are weaker.
10 Stronger: Kaguya Otsutsuki
Kaguya Otsutsuki was the final antagonist of Naruto and just like Momoshiki, her powers were beyond anything the shinobi kind had ever encountered. She was strong enough to take on not just Naruto and Sasuke, but the entire Team 7, along with Obito Uchiha at once.
Kaguya's powers were great enough to reduce an entire space-time to nothing, something that Momoshiki can't do. It is highly likely that Kaguya was stronger than Momoshiki.
9 Weaker: Kinshiki Otsutsuki
Kinshiki is one of the newest Otsutsuki clan members to have been introduced to the fans. He served the role of Momoshiki's guardian. In terms of combat ability, Kinshiki was clearly impressive, known to be strong enough to split planets apart.
Although Kinshiki was quite powerful, he was inferior to Momoshiki Otsutsuki. He ended up becoming a chakra fruit to make Momoshiki stronger.
8 Stronger: Isshiki Otsutsuki
Isshiki is a mysterious Otsutsuki clan member who is known to have partnered Kaguya Otsutsuki long ago. At some point, he made Jigen into his vessel and formed Kara.
Isshiki is one of the strongest characters in the entire Narutoverse, if not the strongest. He was able to fight and defeat both Naruto Uzumaki and Sasuke Uchiha at once and he achieved it without receiving even a single scratch. Momoshiki, on the other hand, struggled in dealing with the two.
7 Weaker: Urashiki Otsutsuki
Urashiki is an anime-only Otsutsuki who tagged along with Momoshiki and Kinshiki for some reason. Although he appeared to be quite powerful, Urashiki was a massive disappointment.
He had the ability to steal the chakra of others and use their powers as his own. However, when he ended up getting defeated by the likes of Jiraiya and Boruto Uzumaki, meaning he wasn't all that powerful.
6 Stronger: Hagoromo Otsutsuki
Also known as the Sage of Six Paths, Hagoromo Otsutsuki was one of the most influential people in the Naruto world. He was responsible for humans having chakra as he spread it through Ninshu, something he wanted to connect everyone with.
Hagoromo was quite a capable fighter as well. He was powerful enough to fight Kaguya Otsutsuki for months and thanks to help from Hamura, he was able to seal her. Hagoromo grew stronger after defeating Kaguya by becoming the Jinchūriki of the Ten-tails.
5 Weaker: Kashin Koji
Kashin Koji is one of the members of Kara whose motives remain unknown to date. Being one of the Inners of the organization, Koji has been scientifically enhanced, meaning he's a powerful character.
According to Koji himself, he was created to destroy Jigen, which implies he is somewhat around the level of the Otsutsuki clan members. However, he was adamant that his powers are far inferior to Jigen's, meaning he's weaker than Momoshiki as well.
4 Stronger: Hamura Otsutsuki
Hamura was the younger son of Kaguya Otsutsuki. Although not as influential a character as his brother, Hagoromo, it is believed that Hamura was relevant to him in terms of power.
Like Hagoromo, he was able to fight against Kaguya Otsutsuki for months without tiring. He is also known to have the powers of the Tenseigan. Hamura was, undoubtedly, quite a capable fighter.
3 Weaker: Might Guy
Might Guy is the former leader of Team Guy and a master of Taijutsu. During the Fourth Great Ninja War, Guy proved to be an incredibly powerful character when he fought and almost killed Madara Uchiha in battle.
Although strong, it is highly unlikely for Guy to defeat Momoshiki Otsutsuki, simply because the latter is much stronger than Madara. Nonetheless, Guy was quite a capable ninja back in the day.
2 Stronger: Naruto Uzumaki
Naruto Uzumaki is the Seventh Hokage of Konohagakure and the strongest shinobi in existence. While Naruto did need Sasuke's help to defeat Momoshiki Otsutsuki, it is important to note that he was at half his full strength during the fight, having exactly half his chakra extracted by Momoshiki himself.
At full power, it is highly likely that Naruto Uzumaki is stronger than Momoshiki. Furthermore, Naruto could also have grown in power since then.
1 Weaker: Kakashi Hatake
Kakashi Hatake is the Sixth Hokage of Konohagakure who was once famed as Kakashi of the Sharingan. In his prime, Kakashi was an excellent Jonin, capable of taking on and defeating multiple strong Jonin at once.
However, he was nowhere near the level of the Otsutsuki beings. Momoshiki, being one of the strongest of their kind, is leagues above Kakashi in terms of power.
