I liked the chapter a lot.
I think Tobi = Obito's dad he would have the same ocular jutsu as Obito it could of been passed down to Obito from him. If it is not his dad then it would possibly be Setsuna - (Wore a mask on the right side of his face) Setsuna could of taken Obito's eye from the side that was being crushed but possibly the eye was left intact.
Reason why it isn't Obito- By the time the 9 Tails invaded Konoha Obito would be in his teens but the "Masked Man" Who fought Minato knew nothing about his abilities that is why he was hit my the rasengan. Also Obito seems incredibly old currently. Another reason is why would he do such a change Kishi has done changes in people before -Second Naruto Movie-But the change is just very drastic.
Reason Izuna is a possib
lity - He was the brother of Madara Eighty years prior to the start of the series, Izuna and his older brother Madara were said to be equals as the most gifted members of the Uchiha clan. They usually competed with each other every day in order to get stronger. Both awakened their Sharingan early in life, and they became the first Uchiha to awaken the Mangekyō Sharingan. Madara used the power of his Mangekyō Sharingan to take control of the clan, with Izuna at his side. When Madara eventually went blind, he took Izuna's eyes to regain his sight. Itachi Uchiha suggested that his eyes had been taken by force, however Tobi insisted that Izuna had
willingly given up his eyes for the good of his brother and the whole clan, seeing that Madara needed to remain strong to protect the clan from its growing number of enemies. Izuna later died honourably in battle, fighting to the death even in his blind state.
Izuna Uchiha was a harmonic and devoted person. He also appeared to be very competitive with his brother, Madara, in terms of skill. Tobi also implies that Madara and Izuna were close as brothers.
Izuna was a fair-skinned man with long, black hair that had a blue tint to it and was tied in a ponytail. His bangs parted down the centre of his face to frame both sides of it. He wore the standard Uchiha outfit which consisted of a high-collared, blue shirt with the Uchiha Crest on his upper back and blue pants which were wrapped up in bandages at the ends. On his waist, he had a bandage belt that held a sack which presumably held ninja tools.
-Naruto Wiki-
Izuna and Madara with their Mangekyō Sharingan activated.
Izuna was noted to be equal to his elder brother, Madara, in every way. Both of them had exceptionally strong chakra, even for Uchiha members and trained daily to hone their skills.[5]
Izuna mastered his Sharingan at a very young age, alongside Madara. When Izuna awakened the Mangekyō Sharingan, his took the appearance of three bars stretching out of his pupil. When Madara took his eyes, the two Mangekyō combined. Izuna's loss of his eyes rendered him blind, but he managed to survive, and continued to battle. This sudden disability however, ultimately led to his death.
Based on his apperance he had same hair as "Tobi" Has so another reason why he was allegedly a possibility.
Kagami - During the First Shinobi World War, he was part of a team consisting of Tobirama Senju, Hiruzen Sarutobi, Koharu Utatane, Homura Mitokado, Danzō Shimura, and Torifu Akimichi. He is assumed to have died at some later point, either before or during the Uchiha clan massacre.
Kagami had short, black, untidy hair. He wore the standard Konoha outfit of the time which included a black suit with armour over it, forehead protector, sandals and a pouch strapped to his waist.
So based on that he would of Known Madara possibly due to the time period and both being
Uchiha's just fighting for a different cause. After the "death" of Obito and Him not getting Hokage after all his attempts. Would make him grow some hatred towards the leaf then his son dying could of set him over the edge. I can't wait for the next chapter D:!
