Tobi and Obito are absolutely not the same person(honestly we have no idea who tobi is, but he is not Madara).It was "revealed" in the episode where Tobi met Sasuke that Tobi is actually Uchiha Madara(but is later revealed he is not as Madara is brought back to life with Edo Tensei.),because he knows the reason why itachi wiped out the entire uchiha clan( which Tobi helped Itachi with),which happened after Obito was dead.The reason why people insist that Tobi and obito are the same person is because of the resemblance it their names.
Possibly,because kakashi's sharingan(left eye) from obito, has power that is whatever he sees it can transfer anything in other dimension/place , and just like Tobi can travel anywhere by dimension by using his sharingan (right eye). They're both using the same sharingan and powers ('cos it come to only one person, obito, and obito himself is Tobi(Possibly)). Kakashi (in manga/anime )can't actually do what Madara/Tobi/obito do 'cos he is not original uchiha(he can access the powers of sharingan but can't deactivate it, which is why he keeps it covered), and only true uchiha can perfect the power of their own sharingan(This is wrong becausethere is plenty of proof towards it but plenty against as kakashi is able to awaken Mangyeko sharingan).
Obito and Tobi are the same person in the Naruto series. Obito Uchiha assumed the alias "Tobi" when he joined the Akatsuki organization. Throughout the series, Obito uses the Tobi persona to conceal his true identity and motives.
Obito is not Tobi. Madara Uchiha is Tobi. How many times must I tell you this, people?!
Tobi and Obito are not the same person. Tobi is Madara Uchiha. It was confirmed by himself. He will be unmasked later in the series.
Tobi isn't Obito. He is Madara Uchiha
Obito is Tobi's father. No! Tobi is Madara,and Madara is 100 years old or something like that.Obito died when he was young child
Yes, Obito is evil. It was revealed in the Manga that Tobi was Obito.
no it is rumered that Tobi is madara uchiha in obito's body but no pein is not obito
Kakashi, Obito, Rin and Minato Namikaze (the leader) were students in the same team. Obito dies and later on it emerges that Tobi is, in fact, Madara Uchiha. No because obito is not Tobi .madara uchiha is a man from before the hidden leaf he is probably hundreds of years old madara was born before kakashi they can not be the same age because Kakashi is 27 Well as shown now tobi is not madara. However there is no way tobi could be obito cause at the time where the nine tails attacked kakashi was still young and tobi was way older when he fought minato. I dont get why people are not using their brains cause that is a proof that tobi is not obito.
Madara Is Not Tobi Madara Raised Obito And Trained Him & made Me Believe In Everything He Believed Tobi Just Wears A Mask Because Of The Huge Rock That Feel On Him Madara Isnt Alive.....Yet
Tobi is Madara Uchiha in Tobi's form!! Obito Uchiha is dead and completely unrelated besides the fact that he is an Uchiha too.
Yes it is true that Obito Uchiha is tobi as shown in Manga Chapter 599
He isn't. Tobi is way too old to be Obito and knows too much about Madara's history
