The Otsutsuki are a powerful and ancient clan of extraterrestrial beings in the Naruto universe. They are known for their advanced technology, incredible chakra abilities, and their quest to harvest chakra from different planets. The Otsutsuki are responsible for the creation of the chakra fruit, which grants immense power to those who consume it. They are also the ancestors of the Sage of Six Paths, Hagoromo Otsutsuki, who is considered the progenitor of modern ninjutsu in the Naruto world. Throughout the series, members of the Otsutsuki clan have been shown to be formidable adversaries for the protagonists. **

The Otsutsuki king is a character from the anime and manga series "Naruto" and "Boruto." He is the ruler of the Otsutsuki clan, a powerful alien race that seeks to harvest chakra from different planets. The Otsutsuki king is a mysterious and enigmatic figure, and not much is known about him. He is often mentioned in the series as the ultimate goal of the Otsutsuki clan's plans to conquer and consume other worlds. **

Momoshiki Otsutsuki is inside Boruto Uzumaki, as he was implanted into Boruto's body during the events of the Boruto: Naruto the Movie. Additionally, Isshiki Otsutsuki is inside Jigen, who serves as his vessel. These Otsutsuki members play significant roles in the Boruto series, impacting the lives of the main characters and the overall storyline. **

The weakest Otsutsuki is generally considered to be Urashiki Otsutsuki. He is depicted as being less powerful and skilled in combat compared to other Otsutsuki members such as Kaguya and Momoshiki. Urashiki's abilities and strength are shown to be inferior, and he is ultimately defeated by the combined efforts of the main characters in the Boruto series. **

In the Naruto series, Otsutsuki Kaguya is considered to be the strongest character, as she is the origin of all chakra and possesses immense power. Uchiha Madara, while incredibly powerful, ultimately falls short in comparison to Kaguya. Kaguya's ability to manipulate dimensions and her overwhelming chakra make her a formidable opponent. Therefore, in a hypothetical battle between the two, it is likely that Kaguya would emerge victorious. **

The Otsutsuki clan's Sharingan have different colors because each member of the clan possesses unique chakra and genetic traits. These variations in chakra and genetics result in different manifestations of the Sharingan, leading to different colors such as red, purple, or even black. Additionally, the color of the Sharingan may also be influenced by the individual's emotions, experiences, and level of power. **

It is not a coincidence that the Otsutsuki clan possesses the Byakugan. The Byakugan is a kekkei genkai that is unique to the members of the Hyuga clan, who are descendants of the Otsutsuki clan. The Otsutsuki clan is known for their powerful chakra and abilities, and the Byakugan is one of the traits that have been passed down through their bloodline. This connection between the Otsutsuki clan and the Byakugan is a deliberate part of the lore and history of the Naruto universe. **
