When he really died, he was 31. After having a change of heart, thanks to Naruto, Obito could fight right until the end and help Kakashi build a new era after the war. He was never given the chance and died at the hands of Kaguya Otsutsuki near the end of the Ninja War.
5 after redeeming his evil actions, Tobi (Obito Uchiha) died aged 31. Tobi initially appeared to be a comical, clumsy ninja who didn't take his role in the Akatsuki seriously.
So Obito and Kakashi were 14 when Obito attacked Konoha during Naruto's birth. We know Obito "died" at 13 during the Kannabi Bridge mission (Kakashi Gaiden). So Kakashi was 13 too. Which means in 1 year, Obito recovered, saw Rin die, Madara died, Obito started recruiting Akatsuki, and attacked Konoha.
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.
If you become a genin upon graduating the academy and the 3 of them graduated together. That means they're older than Kakashi by atleast 4 years. Kakashi became a genin at 5 while Obito and Rin were 9 meaning they were 4 years older than him when they all graduated the academy.
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...
He “died” when he was 12/13 years old. Obito threw Kakashi from the falling rocks, and instead is crushed by the rocks. Obito was actually rescued by White Zetsu on the instructions of an aged Madara.
A child living through the Third Great Ninja War, Obito (Kakashi's teammate on Team Minato) wanted to become the Hokage of Konohagakure, and had an unrequited love for his teammate Rin.
One common theory that fans came up with was that his change in behavior was due to split personality disorder. In the Naruto series, Tobi could have been the manifestation of the fun and goofy side of Obito, which he didn't really get to showcase in the series. He has always been a serious person with big dreams.
According to the wiki Obito was 31 years old in part 2, itachi was 21.
Rin died at a young age, so she only grew to be 143 cm (~4 ft 6 in). Obito, on the other hand, started off at 154.2 cm (~5 ft 1 in) and grew to 175 cm (~5 ft 9 in). Later, Obito measured in at 182 cm (~5 ft 11 1/2 in). Minato was 179.2 cm (~5 ft 10 1/2 in).
In fact, Kakashi admits that Guy is stronger in some ways. Guy can unlock all eight gates and knows how to battle against the Sharingan. He lost to Kakashi in the finals of the Chunin Exam when they were young, but Guy works hard not to lose again to his rival.
4 Obito Uchiha
After having a change of heart, thanks to Naruto Uzumaki, Obito could fight right until the end and help Kakashi build a new era after the war. Surprisingly, he wasn't given the opportunity as he ended up dying at the hands of Kaguya Otsutsuki towards the end of the Ninja War.
Sasori Has a Human Core
Around 20 years ago (before he was introduced in the show), Sasori turned his whole body into a puppet. He created a core out of his human flesh, and it's the only part of him that remained as a human. By discarding his original human body, the puppet form gave him an eternal youth appearance.
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.
Obito was aware of the impression he had on everyone in Konoha, and revealing his true identity wouldn't have created the chaos he desired. Hence, Obito took Madara's identity to intimidate everyone, eventually making the Eye of the Moon Plan progress smoothly in Naruto.
In a short time span, Tobi became an integral member of the Akatsuki and a close partner of Deidara, as the two were sent on several missions for the organization. Even though Tobi's initial childlike persona was due to Guruguru, Obito kept the guise simply to present himself a benign entity to the Akatsuki.
Obito was afraid of Itachi. But it's not that Itachi was stronger than Obito. Up until Itachi was alive, Obito had Hashirama Cells, Kamui, Izanagi and some other common jutsus which were enough to defeat Itachi, if used wisely. Itachi has no counter for Kamui.
Kakashi Hatake
Rin developed a crush on Kakashi while they were in training together due to the fact that Kakashi was a genius, skipping ahead of his classmates. Every time Kakashi was promoted, Rin would plan a surprise party for him.
She was forcibly made into the jinchūriki of the Three Tails Isobu, as an elaborate scheme by Kirigakure to destroy her village. Rin, however, would ultimately sacrifice herself to ensure the safety of the people she loved.
Where Obito actually loved Rin romantically, Kakashi viewed her as someone he needed to protect at all costs, especially after the death of Obito where he felt he failed to protect him. Yeah I think she told Obito (the guy who is in love with her) that she is in love with kakashi.
In truth, Obito was saved from death and trained by Madara Uchiha, but the events of the war left Obito disillusioned with the world, and he sought to replace it with a new one.
Despite his impressive achievements, there is no way Itachi can beat Obito in his most potent form. Obito Uchiha, in his strongest form, was the Ten Tail Jinchuriki. This means he had massive chakra reserves and endurance.
Obito Uchiha (うちはオビト, Uchiha Obito) was a member of Konohagakure's Uchiha clan. He was believed to have died during the Third Shinobi World War, his only surviving legacy being the Sharingan he gave to his teammate, Kakashi Hatake.
