K im gonna wright down final arguments for a bizillionth time.
1. Tobi was born in konohagakure. He was the son of Uchiha Madara.
2. Since Madara was betrayed by his people and killed by Senjui, Tobi grew up to hate everyone and didnt care about anything else then going in his dads footsteps and gaining power.
3. We know Madara came up with Tsuki no Me, Tobi carried this plan out, and dedicated his life to completeing that, instead of having dreams of his own.
4. Tobi was called a shell of his former shell, the name "mirror" in japanease is Kagami, he is jsut a reflection of others. Not having his own dreams.
5. He became partner with Danzo in creating Anbu Root. He adapted their trademarks " Cloaks and masks" and a variety of ninja tools, we have seen Tobi using alot of different tools.
6. Anbu are supposed to recover dead ninjas corpses, after Obito died he recoverd his corpse but he also took his right eye which was intact after the collapse.
7. Since he was in Anbu he knew about Kushinas birthlocation maybe he was even set to guard, he used Kamui to get entrance and took revange on konohagakure which he had waited for a long time, he could have just taken the kyuubi but he used it to attack the village because he wanted to revange the death of Madara.
8. Tobi said he inspired Yahiko to form Akatsuki and gave the rinnegan to Nagato, there are 2 ways i can think of, one is that he was responsible for the war somehow, the second is that since Madara had rinnegan, perhaps he took theme and implanted them into Nagato.
9. He has wrinkles and looks to be the same age as Danzo.
10. He wanted Sasuke to kill his former teammates. to fully erase his identity.
11. Since he was in Anbu and with Danzo, he also collaborated with experiments with Orochimaru on Shodais cells, thats who Oro and Kabuto knew of his real identity and Itachi maybe knew since he met him in Anbu.
The name Tobi comes from Tobirama his mentor, and Madara is from his dad/rolemodel.
it would be cool if Madara gave his eyes to Tobi as a boy just like his brother had given the eyes to him, and told him to use them to carry out his plan.
This would truly make Tobi a "good boy".
