Madara, Madara, and Madara (Naruto)
Madara's first thought, looking down at the small unsure children in front of him is
what.
His second is
no, seriously, what?
Madara Uchiha, once upon a time was someone else. Pretty obvious if you know how Uchiha Madara would have been if he didn't remember another life, in his opinion ; but no one does. So to other people he just seems as angry as any other Uchiha, and to the Uchiha he's slightly more rational than the typical clansmen.
That's about it.
Of course there's other things those closer to him have noticed - notably, his last living brother Izuna likes pointing out things about Madara's behavior to him on his off-time. Like how he tends to have much more flexible thinking then the average shinobi in this era.
In Madara's professional opinion - if a woman has enough hand-eye coordination to clean, she can damn well slit someone's throat. Maybe if this was a kinder world he'd prefer if no one had to fight at all, but well - that's idealistic in a world where living past 15 with all your limbs intact is seen as a miracle.
For some reason, his clansmen disagree with the idea of kunoichi being more common. He thinks them to be fucking idiots, and conveys this notion to them often.
(Madara thinks using only half their available forces is stupid - the Senju and the Uchiha have been in a stalemate for generations, but the Senju send out both men and women while the Uchiha exclusively sends out men. How much of an advantage would they have, if they treated their forces more equally. He looks upon the battlefield, covered in corpses not all Senju, and covered with corpses of many not even over the age of 16 - and he thinks, 'how many of our people would still be alive, if we had just but four more shinobi on our side, on this battlefield?'
He hates that no one seems to be in a hurry to change anything, despite his yelling about it.)
Izuna looks at Madara's behavior a lot, actually. Maybe he just prefers the idea of noticing something unpleasant and stopping it while it's a seed instead of a fully grown tree. Maybe he just doesn't want what happened to their first brother to happen to Madara - who knows, really.
Madara likes to think he pretty much got over his old life. He remembered it, but you can't really live in the past - it's gone, and Madara is here now. Trying to claw his way back into a society built on half-kept peace in a modern age after living in this one for so long would drive him mad.
He remembered the smaller details, and kept many of the smaller opinions - killing animals for no reason is fucked up, sending children who haven't even hit puberty to a battlefield is fucked up, and as long as someone can hold a knife, they can kill someone. Men and women should be treated with equal amounts of intolerable shittyness - if a man can go to a battlefield at fourteen, so can a woman. Inversely, if a woman can sit around in a house and do nothing but cook her entire life, a man can too. It doesn't matter who you romance or what you have in your pants, if you want to do something and it isn't killing specifically him or his brother, you can do whatever the fuck you want.
Okay maybe he's kind of..changed his opinions a little. He vaguely remembers being a lot less lax with death before, but well - humans are built to adapt, he just followed the example of the era while discarding some of the nonsensical shit. Just about basically everything that annoys him though - so he ends up discarding a whole lot of shit.
So you may be wondering, "Oh great Madara-sama sir, if you're here, what about the plot from hit television series Naruto?"
Madara frankly does not care about hit television series Naruto, seeing as televisions don't fucking exist here outside of really rich nobles and extremely boxy ones that barely play three channels.
But you're probably specifically thinking more about konoha's creation when you ask that.
Tiny Madara, changed or not, still liked the idea of not sending six year olds to battlefields - and if playing at a river with some overemotional loser with a bowl cut was the start to that happening, he was on board. He met Hashirama, talked about peace and love on the planet earth or whatever, got caught by Izuna and ratted out to Tajima, all that.
The main difference was that Izuna had lived through his confrontation with Tobirama years after the fact because of Madara's extreme pestering to learn medical jutsu when they were younger, so when Madara and Hashirama became their respective clan heads after years of fighting and Hashirama proposed peace - he agreed pretty quickly.
Now, eight years after the founding of Konoha and seven years after other fuckers stole their idea and also made their own hidden villages ; Madara came face to face to what looked to be a child that looked almost exactly like Izuna had when he had been younger - if not for the coloring being entirely different, and the hair being much longer.
One may wonder why he had been called to pick up what one may assume is Izuna's spawn upon a quick glance - but the answer became apparent upon the fact the child holding onto the much smaller scale Izuna seemed to be Madara's tiny little clone of his own. Apparently, they're twins. The caretaker of the orphanage - a woman named Shikano, if he recalled correctly - had told him that they were both biologically his children, according to the scans done with Nara medicine.
Which, sadly, doesn't make any fucking sense considering Madara is literally unable to have kids.
Yeah, tmi, he knows, but you're also reading this for the personal and intricate details about literally the entire rest of his life so get the fuck over it.
Madara was poisoned by the second clan matriarch when he was young. He lived because of some damn good healers and his natural chakra trying to fix the issue the moment it hit his system - but he became permanently infertile because of it. He didn't really cry over it, if he wanted any kids he'd just make some ; lab experiment style. If Orochimaru could manage it while being half-insane, Madara could probably do it too.
The clan kept the whole thing hush-hush, so it's not a well known fact by any means - but it's definitely not something he makes any real effort to hide. Somehow, despite that, the kid was literally Madara's carbon fucking copy down to the very expression. His clan literally would rather die then let a bastard child run around in unfamiliar territory - too much pride for that - and Madara's signature hair is unmistakable.
So, there's two possibilities. One is that this is a descendant of the clan that somehow came from a displaced Uchiha - doubtful, the Uchiha were too keen on family to let anyone slip through the cracks.
Two, someone else did the lab experiment shit for Madara - equally as doubtful, seeing as science is seen as half-witchcraft half-nonsense by the masses still. Orochimaru, crazy as he was, unfortunately revolutionized how people saw science as a subject and how much potential it had.
So both options are a no - which means the third option that these aren't his kids at all has to be the logical answer. The only real option here would be to find them their real parents and leave them both in their care but-
the Nara clan wouldn't be happy with that. Putting one of theirs in charge of the orphanage was part of a larger program of letting clans have vital roles in the village as a show of trust - blatantly disregarding medical scans done by a Nara would not only signal that he thought their methods are untrustworthy, but that the show of trust had been shallow.
Even if he did decide to break the fragile trust between the Nara and the village over these children, he has no way of knowing their actual parentage considering the fact the most advanced paternal tests in the village were, again, done by the Nara. The Senju were good medics, but Nara were much better healers in day to day aspects - if you're a Shinobi with an injury you can't heal you go to the Senju, if you're a Shinobi with an illness you cannot place you go to the Nara.
Civilians go to the Nara much more than the Senju - making them vital pieces in civilian-shinobi relations, a still relatively unexplored territory at the moment.
He's locked in - he denies relation to them, he possibly breaks the entire village into shards within less than a decade of existence. He claims them - despite being pretty damn sure he's not related to them at fucking all - he takes children from a young couple out there, one that will probably assume the twins died trying to swim through the Naka or something equally as tragic and unfortunately common and mourn them for the rest of their lives while they're quite alive and perfectly safe within his care.
....Fuck, he hates politics.
