Toneri Otsutsuki is known to be one of the remaining Otsutsuki clan members in the Naruto or Boruto series. He first appeared as a villain character in Naruto the Last Movie. In his movie he intends to destroy the Earth.
Then, he also re-present in the anime Boruto and the first time he appeared in silhouette in his dream Boruto. Toneri is one of the strongest characters in which he himself is capable enough to match the strength of Naruto Uzumaki.
Not only that, it is known that Toneri was the first time to awaken the eye power of Tenseigan, after Hamura Otsutsuki. Since then he has gained comparable power to gods.
There are a lot of Naruto fans who underestimate Toneri, but in fact he is very strong. But, what power is owned though in the movie Naruto of course we feel confident he has not showed his true ability.
So here I will discuss maybe soon we will see the true ability of Toneri. Plus Toneri appeared in the anime of Boruto in his dream, it is likely that Toneri will have an important role in the future story of Boruto.
Immediately take a look at how important the role of Toneri will actually appear in the storyline of the anime of Boruto: the Next Generation, below:
Toneri is the first person to tell Boruto about the power of his eyes that is rumored to the name of the power of the eye of Boruto Jougan. Toneri is believed to have more or less information about Boruto's eye strength and he also mentions that Boruto is the only hope of mankind.
Although we do not know more details about the purpose of the meeting or the rise of Toneri in Boruto's dream. We can ensure that Toneri Otsutsuki is there for a reason. chances are he knows about Jougan because he will have an important role in the Boruto series later on.
So the conclusion and his guess is that there is a chance Boruto will be trained by Toneri Otsutsuki sometime in the future. In addition we also know that other Boruto teachers are Sasuke Uchiha and added with Toneri of course Boruto will definitely grow stronger than his current father later.
Can be sure later Sasuke will realize the presence of Toneri who will come to Earth from his residence on the Moon. Especially his intention to discussthe power of Boruto's eyes. Surely the role of Toneri seems to be very significant.
Because heis the one who tells the beginning about the power of the eyes of Boruto so it can be felt later he will help Boruto to master the power of the eye. This is what makes Sasuke will have more opportunity to train the Uchiha Sarada to master the Sharingan.
jougan is one of the highest Doujutsu powers in Naruto's world. However, no one ever saw it. So, of course no one will be better able to train the powerof this Boruto eye, except Toneri Otsutsuki.
Further more, it seems that Toneri has its own unspecified information about the Otsutsuki clan and all its members. Previously he already knew that Momoshiki Otsutsuki and Kinshiki Otsutsuki have come to earth. In fact he also knows a lot about Otsutsuki remaining in other dimensions.
Although previously Toneri was asked to stay on Earth by Naruto, but he refused because he wanted to see the earth's peace from the moon. But, we believe that someday Toneri will eventually come to Earth.
At least, Boruto needs someone who can teach him about the power of his eyes. Therefore to help mankind, Toneri otsutsuki may actually come to Earth in the next story line in the anime series Boruto: the Next Generation
