Oh man, a biological Shikasuke child? Well, actually, even an adopted Shikasuke child I’d be a little worried about.
Mostly because as they are still such children themselves right now (even with Shikako’s reincarnation, she’s a teenager up against monsters and murderers and that’s really… she comes off as a very mature and mostly rational teenager, but still a teenager) and I’m hesitant to extrapolate what kind of adults and thus what kind of parents they’d be.
(I mean, I guess if I were to write something like this it would be Shikasuke child traveling back in time (or, alternatively, Shikako/Team Seven traveling forward in time) so that Shikasuke child meets Shikako when they’re all the same age.
Which would actually be kind of hilarious and… I mean, it’s happened before hasn’t it? Naruto travelled back in time to meet his parents in the anime, right? And he doesn’t even have the penchant for fuinjutsu experimentation or possible Mangekyou Sharingan omnipotence that Shikako and Sasuke do.)
Uh, anyway. I guess the thing is that on a purely biological point, an Uchiha-Nara child would be pretty dangerous. The Sharingan mixed with a spiritual predisposition for shadows? I would not want to be on the wrong end of that kunai. But I guess you can consider the mix of genes in three ways: either the child will have a genetic preference towards either the Uchiha traits or the Nara traits, the child will have both with lesser intensity than their parents, or the child will have a unique combination of the two.
(I mean, can you imagine how horrifying it would be if all the kid needed to do was connect to your shadow and you get sucked into an unbreakable genjutsu? WHYYYYY? Or, alternatively, all you need is eye contact and this kid has control of your body? OMG O_O )
That being said the other “clan traits” of the Uchiha and Nara–being powerful but emotionally unstable vs being intelligent and lazy–would probably end up in a kid that, yes, would be at risk of both clans’ psychological problems.
But you also have to consider that a lot of Sasuke’s emotional problems are because he legitimately has PTSD and basically raised himself at the scene of his family’s murder. Like… it’s surprising he’s as well adjusted as he is in canon before the Orochimaru bite.
This child would (hopefully) have at least one parent around growing up (seeing as how both of them are essentially un-killable) and possibly biological/honorary uncles and aunts, grandparents, and the entire Nara clan (Which might as well be the entire Akimichi-Nara-Yamanaka alliance) so there’s no chance of this kid ending up like Sasuke because that’s a fairly individual set of circumstances that will almost definitely not crop up again.
Will this child possibly end up like their parent because of a different reason (like Boruto basically acting like Naruto, not because he’s an orphaned pariah but because his dad is probs depressed and bad at parenting)? Yes, maybe. But I think this kid, especially seeing as how their mother was integral in making the Rookie Nine/Ten more cohesive than canon, will be the “it takes a village” kind of child than the simultaneously-put-on-a-pedestal-but-considered-a-potential-walking-bomb that was Sasuke’s childhood.
Actually, I guess maybe I should try to extrapolate what Sasuke and Shikako might be as parents… but another reason why that’s so hard for me is that I don’t actually think they want to be parents. Like, sure, Sasuke wants to “revive his clan” but that’s a lot different from “having and raising a child.” Whereas Shikako, during the babysitting missions they had early on, had been good at it but had also not been super keen on it.
That being said. DoS Sasuke wouldn’t be weirdly exiled from Konoha like canon!Sasuke is, so he would be around more for their kid’s childhood than for Sarada’s. Which is not to say that he’d be around all the time (maybe his village lockdown days will ingrain him with a sense of wanderlust, or maybe he really will just settle down okay in Konoha without the driving need to get stronger/revenge always pushing him forward) but definitely more often.
Ditto with Shikako. I mean, I kind of wrote a thing about what I thought a future/epilogue Shikako might be like but that’s literally only one of many possibilities. She, too, may prefer settling down since, presumably, the Akatsuki/Danzo/Madara/Kaguya threat has been taken care of. And we have seen her be especially academic–when not in danger, her tendency seems to be to research and invent–and staying in a peaceful Konoha would help with that.
I don’t know, anon, it’s still a little difficult for me to imagine. I mean… I actually think–if they are both active parents and, more importantly, the two primary guardians–that Sasuke would be the one who is better at the emotional matters than Shikako. Like, if that child gets scared? Shikako would probably reassure them that there’s nothing to be afraid of–which isn’t bad parenting–but Sasuke would be the one to coach that kid through their fear, be like “if there is a monster under the bed, we will do this and this so the monster can’t get you” (and then proceed to teach their child Grand Fireball, probably) which is acknowledged to be a better method of dealing with your child’s fears.
Just… conscientious snake versus rabid badger, you know?
I think this kid will be scary. I think this kid will be smart and emotional and ruthless. I think this kid will probably overstep their limits on multiple occasions, will fall into the black at least once, will hurt people around them when they’re angry. But that’s what a lot of kids are like–probably both in the Naruto world and in the real world.
This kid will have the advantage of having a loving support system. This kid will probably love their friends and family fiercely, will be loyal and the best person to have beside you in a fight and watching your back. This kid will probably invent jutsu that impress, bewilder, and exasperate people because do you know how much paperwork this is going to be? Let’s be honest, this kid will probably end up being the Hachidaime or best friends with the Hachidaime and will make their parents (and uncles and aunts and grandparents) hella proud.
So I don’t think we need to worry too much, anon, I think this child is going to be alright 🙂
