Obito Uchiha, also known by his iconic alias, Tobi, as well as the Masked Man, is one of the main antagonists of the Naruto franchise. He is the true leader of
Obito Uchiha, alias Tobi was a memorable villain as long as he was behind his mask. As soon as he was revealed to be Obito, nobody recalled him for him being Tobi. Because of this, Tobi has now become one of the most disregardable villains of the series.
Obito Uchiha is, perhaps, the biggest villain in the world of Naruto. Obito became a villain after witnessing the death of Rin at the hands of Kakashi. Convinced that the world of dreams was the way to go forward, Obito did everything in his power to help Madara achieve his goal.
Obito's hate for the Uchiha was simply a result of Madara's animosity towards the clan, as they had betrayed him long ago and had decided to side with the Senju-led government.
Obito grew up to be the real leader of Akatsuki. He started the Fourth Great Ninja War under the name of Madara Uchiha. However, after Naruto successfully used the Talk-no-Jutsu against him, Obito realized his mistakes. Later, he helped Naruto and the rest of Team 7 to beat down Kaguya Otsutsuki.
Very few, if anyone, could surpass Madara in power and in Shinobi abilities. He was also secretly behind most of the conflicts in the series, making Madara the true main villain of Naruto.
Being a Senju, Tobirama was magnificent when it came to combat. He was powerful enough to fight both Kinkaku and Ginkaku at once, which is certainly a testament to his abilities. However, Tobirama was definitely weaker than his brother, who openly admitted to being inferior to Obito Uchiha.
Itachi wasn't strong, he was super smart. Obito feared his smartness. He knew Itachi would destroy any plan of obito as long as he's alive. Obito was not afraid of dying, he was just afraid of his plan getting ruined.
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.
Seems to me that he was simply intended to be an additional pawn in case he needed more firepower. His plan during the Gokage summit was to have Sasuke weaken the Hokage in the hopes that he could then negotiate on more favorable terms. As Obito noted, that failed.
Although he changed his views mid fight in the fourth ninja wars, that would also cause his demise. In an attempt to save Naruto, Sasuke and Kakashi, Obito Uchiha sacrifices his own life and gets killed by Kaguya Otsutsuki.
Obito and Kakashi had a complex relationship. Obito envied Kakashi's natural talent, and this was further enhanced by Obito's own inadequacies. Unlike most of the Uchiha, Obito wasn't a prodigy and struggled with many of the basics.
Tobi was said to be Madara but later on you find out that Tobi is really Obito and the real Madara really did die and is just a body used for Kabuto's reanimation justu. There is much speculation surrounding the identity of Tobi, the masked man who has been a central figure in the Naruto series since its beginning.
Witnessing the death of the one he loved so much turned Obito into a villain who is primarily responsible for the Fourth Great Ninja War.
Because he knew the truth that Kakashi didn't kill Rin rather Rin killed herself throwing herself onto Kakashi's Chidori. And he hated Kakashi because Kakashi failed to protect Rin, that's it.
Obito in his Tobi persona was Kishimoto's favorite Akatsuki character to draw, because of his simple mask. His nickname (Tobi) comes from Obito calling him Guruguru (グルグル), an onomatopoeia for turning round and round or going around in circles.
However, the two are willing to end each other to achieve their respective goals. Ultimately, the battle is a stalemate and a true testament to Obito's strength. Kakashi is one of the strongest characters by the end of the manga and the show, but Obito is definitely his equal.
Obito's Ability To Phase Through Anything Would Be Too Difficult For Jiraiya To Handle. Obito was able to phase through anything, possessing reflexes to obviate Minato. This is profoundly impressive considering that the Fourth Hokage was considered by many to be the fastest ninja to have ever lived.
However, Obito can't defeat Sasuke, as the latter, after receiving chakra from the Sage of Six Paths, became stronger than him and was able to fight against the likes of Madara and Kaguya.
Obito had given one of his Sharingans to Kakashi when his left eye was impaired. Obito was confident that he was about to succumb to his injuries, so he decided to give his eye to Kakashi. In the future, during the events of the Fourth Great Ninja War in Naruto, Kakashi ended up losing his first Sharingan to Madara.
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...
Jiraiya. Jiraiya was an exceptionally competent shinobi, and he was the only member of the Legendary Sannin who could actually beat Itachi. He was trained by the Third Hokage, and learned how to use Sage Mode while training with the toads of Mount Myoboku.
Zetsu was the weakest member of the Akatsuki. He specialized in infiltrating different places and gathering intel. Throughout his time in the organization, he was never involved in a serious fight that would show his fighting capabilities.
4) Obito Uchiha
After becoming the Jinchuriki of Ten-Tails, he became immensely strong, fast, and was nearly impervious to any damage. Although Minato defeated Obito once when he was alive, if the latter fought the former in his Jinchuriki Transformation, he could defeat him with ease.
