During his time with the organization, Itachi completed several important missions, recruited other members, and partnered with Kisame and Juzo. Itachi died at the age of 21 during his battle with Sasuke.
Notes: Itachi is approximately 8 years younger than Kakashi and approximately 6 years older than Sasuke (dated by the Uchiha Massacre when Sasuke is age 7 and Itachi is 13).
It has been stated that Itachi was 13 when he massacred the clan .
Kakashi: approximately 8 years older than Itachi which would make him 21 at the time of the massacre.
Well Itachi was about 20 when he died, and in Boruto it was confirmed that it has been 10 years since the Fourth Great War, so that means Itachi would be around 30 in Boruto.
Koji Kashin (果心居士, Kashin Koji) was an inner of Kara operating in the sector containing the Konohagakure. He is a clone of Jiraiya created by Amado for the purpose of killing Isshiki Ōtsutsuki.
Itachi is the older brother of Sasuke Uchiha, and is responsible for killing all the members of their clan, sparing only Sasuke.
Minato's reign was short, and it lasted for just 2-3 years. Since Minato died at the age of 24, it can be assumed that he became the Hokage at the age of 21 at the maximum.
If Shisui was his sibling he would definitely know since they were both living with the Uchiha and Shisui should only be around 4-8 years older than Itachi who is 9 years younger than Obito, hence they should also know each other...
Kakuzu was the oldest member of the Akatsuki. He lived during the time of the first Hokage, whom he tried to assassinate. The attempt ended in failure, and after returning to his village, Kakuzu killed the elders and became a rogue ninja.
In 2009, Itachi died in the anime after a climactic battle with Sasuke, wherein he gives Sasuke his Sharingan power. Having been wracked by guilt, Itachi had always known that the only way he could meet his end was by Sasuke's hand.
How old was Kakashi and Obito when Rin died? I think Kakashi was a bit younger than Rin and Obito, being around 11ish and Obito and Rin were roughly 13.
What is Neji's IQ? Neji is supposed to be a genius and characters like Asuma and Jiraya score a 4.5. While characters like Itachi, Hiruzen, Minato, Shikamaru, etc score a 5.
3 Kakashi Hatake Outdid His Comrades & Became Jonin At 12 Years Of Age. Without a doubt, Kakashi Hatake was very talented as a child and way ahead of everyone his age. He became a genin after graduating at the top of his class at the academy at the mere age of 5.
Itachi once mentioned that Shisui is stronger than him, and given that Itachi was able to beat Orochimaru, Shisui would be able to beat Orochimaru.
Itachi was able to fight against Naruto Uzumaki in his Nine-Tails Chakra Mode, something that Pain could never do. He was also able to incapacitate Nagato Uzumaki, and it is quite easy to see that he could definitely have taken on and defeated Pain in combat.
Even though he had the Tsukuyomi, Amaterasu, and presumably the Susanoo at his disposal, Itachi knew that he could not overcome Jiraiya's strength.
'Naruto' characters with a chance against Itachi
As stated in the series, it seemed that Sasuke's Genjutsu abilities were indeed stronger than his older brother. Combine that with the powers he later gained through his Eternal Mangekyo Sharingan and Rinnegan, and it seems that Sasuke has him beat.
If Minato were alive, he would've made sure that Naruto never lacked anything in life, including comfort and a loving parent. Minato would have been Naruto's rock who'd help him become a splendid human being.
Jiraiya was born on November 11th. For part one of the show, he is between 50 and 51 years old. Come part two, he's 54. Often serving as comedy relief, Jiraiya might seem like an idiot on the surface, but he is one of the strongest shinobi in Konoha's history.
As mentioned, he was extremely powerful in his teenage years, even before reaching his peak. Had it not been for his illness shortening his lifespan, Itachi would have grown to surpass the greatest of shinobi and would have totally redefined levels of power.
Jiraiya stands at a massive 191.2 cm (~6 ft 3 3/4 in). According to Studio Pierrot's model sheets, his sandals add an additional 7 cm. The studio also claims he was 153cm as a child. Orochimaru's height swings from 179.4 cm to 172 cm to 179.5 cm (~5 ft 9 in), presumably because of all the body-swapping.
