#obito analysis

I) Madara's presumed heir?

Even if we know, that Madara never wanted anyone in his back, or neither an official heir or disciple. there is few indication than Obito in a twisted way, was selected as his heir and the only one worthy of following his path.

From the databook we learn than the gunbai, a war fan symbol of the Uchiha, always belongs to an the leader, and should be passed down on his successor. But when Madara left the village, and presumably was destituted to his leadership, he never abandoned the gunbai. In his mind maybe, he was still the leader, or no one for him was capable of taking his place.

After Madara's natural death, Obito inherited his name, his identity and of course his belongings which included the gunbai. We never witnessed any Uchiha using it as weapon or symbol except Obito. And first move of Obito after realising that Madara escape Edo Tensei, is to give him back his gunbai. and in a way abandoning his heritage for realising his own objective.

II) What did Madara see in Obito ?

There is something about him that the entire Uchiha clan, Konoha village and the best shinobis of their time couldn't see about Obito but Madara can. Ok we know he said he chose him for his naive personality but that's not enough. Naivety don't qualify you to be one of the most dangerous skilled shinobi ever.

Let's just remember Obito's achievement after spending just few years under Madara's traumatizing internship :

able to destroy a whole Kiri ninja section on your own at 13 years old

reinventing still as a teenage Akatsuki into a world wide terrorist organisation

putting under a genjutsu for years the fourth Mizukage (not your average joe shinobi)

putting bijuus under a genjutsu,

Like Madara being able to summun Kyubi like your personal toy

best actor studio's skills, and playing Madara and Tobi for years

fighting around 15/16 years old as equal his ex-sensei Minato Namikaze, an actual Hokage (still not an average joe)

outsmarting extremely intelligent shinobis : Itachi, Sasuke, Danzo, Oroshimaru.

Slaughtering all by himself the strongest Uchiha fighters (except Fugaku)

Manipulating the 5 kages including Onoki who knew him personally (an other bunch of no-average joes) into believing that Madara is still alive.

Launching world war 4, alone.

Invoking Gedo statute as if it was a tiny pet, while Nagato is seen physically struggling to master it.

Controlling juubi as a jinshuriki, sure it take longer than Madara but it's still an achievement.

One can tell it's because of Hashirama's cells but we know from Oroshimaru's experiences on Yamato and plenty innocent children that being compatible with Hashirama is extremely rare and cause many deaths. So again Obito has an immense strength of his own that no one except Madara was able to exploit.

When you think about it, Obito is really that goofy guy undercover psychopath that you shouldn't invite at your family dinner or he'll succed to create a family civil war and make everyone believe that you are the sole responsible for the bloodshed.

III) What was Madara's plan and Obito's own agenda ?

Fight me if you want but Obito is a way more violent villain than Madara and by far. What's scary about Madara is both his illimited raw power and his inflexibility to accomplish his plan. If you are on his way he will crush you, if you're not he won't care about you anyway, if you can entertain him he will dance with you a little bit. But he never tortured for fun and only killed trained shinobis, never civilians. Everyone who encountered him had previously signed for the dangerous life of shinobi and if you feel uncomfortable by him using and killing Rin, ask yourself how come 13 years child soldiers including Obito and Kakashi were still a thing during the third Shinobi war while the whole concept of Konoha was to stop those practices ? Yes, send your complains to your Hokage. Only Nagato is a question mark, we don't know how both of them met, and how he end up with Madara's eyes. Did he save his life in a similar way he saved Obito's ? Did Nagato had some kind of eyes illness and need transplantation ? Or did Madara just ruthlessly pluck off eyes of a baby ? We really don't know. Only Black Zetsu is still alive, sealed in some dimension to answer this question.

Obito is a total different kind. He has an appetite for perversion and torture of both shinobis and innocents. And he did it not once but repeatedly. Even if he hid himself behind the idea that « this world doesn't matter anymore since Rin is gone », instead of urging himself to realise the Tsukuyomi's plan, he took the time to have some fun & revenge.

What was the necessity for him to launch Kyubi on Konoha resulting in a lot of civilians death ?

He felt no hesitation to play with Naruto's life, and kill both his sensei Minato and her wife who just gave birth.

What was the need for him to involve himself into Uchiha's massacre ?

If we admit that traumatizing Itachi by killing his teamate was a way for him to create future Mangakyo sharingan in case he is loosing his own sight. Why did he kept this huge collection of sharingan eyes, his own people, that will most likely make Danzo very jealous.

The cynical pleasure he took in Kiri. The village of the Bloody Mist , under the fourth mizukage was in fact his creation. In a way Obito who always dream to be an hokage had been de facto the actual Mizukage and he made of Kiri an extreme representation of what is actually a shinobi village : zero-tolerance policy against any dissent, the practice of pitting children graduates against each other in death matches, exploiting money from the weak. Resulting in revolts among kiri shinobi (Zabuza whole life and arc)

I think Madara's plan was more straight to the point than Obito : Collecting the Bijuu, befriend and control Nagato and resurrect him, lauching the tsukuyomi to the moon. While Obito very early showed that he will do the plan but in his own fashion.

Edo Madara was surprised to discover a new war but not anymore when understanding it was Obito's idea. He knew already Obito's taste for creating disorder. And black Zetsu from distance was able to update him on the situation post-resurrection. From annihilating the Uchiha clan, destroying economic system of shinobi through akastuki, destroying politically Kiri as a shinobi village, finally destroying the whole 5 villages through war.

In a way, Obito is a perfect Aquarius villain. A genius mind who made him unpredictable and dangerous, a keen understanding of the shinobi system and how to pervert it. A love for chaos. A detachment from emotion.

So to answer my own question : What Madara saw in Obito, he saw a perfect « disciple » because he was a perfect mix of him and(I think) his deceased brother. We can tell that Obito share in the beginning the same pure kindness toward those he loves and the will to protect them. But Obito is outgoing, fun, and deeply excentric which is far from Madara's stern personality. About Izuna we don't know much but that he has the exact birthday than Obito, 10th of february. And oh what a coincidence ! But Kishimoto never does anything randomly.

Having the same birthday doesn't automatically made you a clone but still, it gives you the same set of cards in life, the same energy to play in the world. And there is only one ninja that Madara knows in full details, from the character, the style and the potential skill not Hashirama, only one with whom he knows from cradle, he trained endlessly, fighted side by side and lead the clan as War Lord up to his 24 years old : Izuna Uchiha. Madara then most likely felt the same energy in Obito which made it easier for him to manipulate and train when it's someone that you feel so much familiarity. And lastly, Obito seems to be a direct descendant of Madara himself (which I doubt but who knows ?) or from Izuna (most likely). and it is known many side of abilities are hereditary. Apples doesn't fall far from the tree, right?

It's as well interesting to note that if Obito seems to look physically more like Madara and (by deduction) spiritually more like Izuna. Sasuke is the opposite. Spiritually close to Madara in character and through Indra's reincarnation, but physically a twin of Izuna.
