I’m going to assume you mean Naruto canon when you say original timeline, because otherwise to go through all of my fandoms would be O_O
I think there’s a difference in handling the knowledge in an internal/emotional way vs handling the knowledge in an external/make-changes kind of way. The first largely depends on how a person finds out–whether it’s something that, in the case of DoS, Shikako tells them or, somehow they find out from, like, a vision from beyond or a canon character dimension travelling and exposition dumping from there–whereas the second depends on their resources (whether they even have the ability to make changes on a significant scale) and personality (whether they would even want to.
Like, I’ve mentioned previously that Shino would make a good confidante for Shikako, not because he would particularly make a lot of changes, but because he would, if not believe Shikako immediately, then at the very least accept the knowledge with a certain level of proof (which is easy enough considering the Aburame’s history with Danzo.) So he’d be the first type of “handling” the knowledge of canon.
All that being said… I kinda want to do both for all of them mostly because this prompt would help me further conceptualize characters in a way I hadn’t considered before. So, both Emotional Handling and Influential Handling for DoS, Externality, (In)Difference, and Counterpoise? Hm, if there’s another series you’re interesting in, lionhead, just let me know and I can add that later.
Dreaming of Sunshine:
Emotional Handling – I’m going to stick with Shino for this one, actually. Regardless of if he finds out from Shikako or from some other means. Second place I would say Ibiki, but I’m reluctant to do even that much because of my own fanon that Ibiki and Yoshino are BFFs so he probably would be second hand messed up by the changes of Yoshino’s family composition.
Influential Handling – I don’t know if there is a singular person I would say is best for this, but the ones I’m thinking of all have a certain… flavor to them. In no particular order: Iruka, Ibiki, Aoba, and Shizune. And the thing they all have in common is that they have influence within the village but not the combat prowess to handle S-rank nin by themselves. So they would have to make changes with a softer touch. Would Iruka emotionally handle canon knowledge well? NO WAY. But he is in the position to not only influence Naruto (and other former students) directly but also to affect administrative decisions. Also, Danzo would never think of Iruka as a threat.
Ibiki, Aoba, and Shizune would probably handle the knowledge with better grace than Iruka, but they don’t have that direct connection with the kids that Iruka does. And this could be a positive and a negative, but they’re all also better than Iruka combat wise so they may be tempted to make changes in person which may cause them to bite off more than they can chew.
So the thing about Externality is that even I haven’t decided whether or not Tetsuki knows about canon, or how–was Naruto a manga in the KHR world or can she perceive the canon version of the world in her dreams?–so I’m going to exclude her for now.
Emotional Handling – Weirdly enough, I think Naruto would handle it best. Not because he would use it, but because he would be galvanized into doing better. Whether that means keeping Sasuke in Konoha or being a better teammate to Tetsuki and Komadori or making sure to protect the people he couldn’t save in canon. Although, I suppose it depends on WHEN he gets the knowledge. Like, if he gets it before the canon graduation time, then it’s unprovable and basically a really weird dream to him–why would he be on a team without Tetsuki and Komadori?–but if its after canon graduation time, that is, after a genin-for-a-year Naruto gets put on a team with recent graduates Sasuke and Sakura, then he might take it as a challenge.
Influential Handling – Ibiki, Aoba, and Shizune for the same reasons as in DoS–since Externality is in a similar vein of OC–but instead of Iruka, since he isn’t the teacher for Testuki, Komadori, and Team Gai’s year, I would add Anko to the list.
Specifically after Tetsuki has joined Intel/T&I. Well, I mean, Anko knowing about Orochimaru’s future movements is already pretty good influence-wise (although, I’m concerned that Konoha would be “concerned” about how she got that information) but if it’s after Tetsuki has joined Intel/T&I and become Anko’s kouhai then Anko will know that she can use Tetsuki to act on her behalf as well as passing Orochimaru’s future movements along to Ibiki and such.
And I guess, for similar reasons, Tsunade would be good but only after she’s already become Hokage. Because her hands are tied as far as throwing down directly with Akatsuki since she has a damn village to run, but she’ll know that Tetsuki is a piece on the board that she can use in a myriad of ways.
Since Kiyoshi definitely knows about canon and is trying her utmost to not get involved during her first decade and a half, then doing an abrupt 180 and getting overly involved in specific people’s lives, I’m going to exclude her.
This probably won’t make much sense given I haven’t actually written enough of (In)Difference to have a firm timeline and, unlike Externality and Counterpoise, it doesn’t follow the usual stations of canon. Which brings up the main point: except for a few flashback type situations, most of canon happens decades in the future. Any changes, even minute, will have massive consequences. Additionally, in a way, it’s harder to prove but easier to stomach so… hm… let’s see…
Emotional Handling – When they’re younger, genin/chuunin age or so, Orochimaru would handle it best. Not because he really believes Kiyoshi (if it is, indeed, coming from Kiyoshi) but because on the unlikely chance that it is true then he is still capable of course-correcting. Also, if he was, as I suspect, Nawaki’s jounin-sensei (or captain, if we’re going with wartime terminology) then being able to prevent his death–which Kiyoshi somehow does–will help a lot in keeping him sane and not completely evil.
Team White Fang would also handle it okay but only as a team. I don’t know why I feel certain about this, but, I dunno, they’re 2/3 my characters so there.
Influential Handling – Actually, all of the above wouldn’t be too bad in terms of influencing things. Orochimaru, obviously, just has to not be a complete sociopath and never work with Danzo (or, even, just kill Danzo outright) and already he’ll make the future a better place. And Team White Fang is either A) Sakumo, father of Kakashi who is in line to affect ALL the things or B+C) a shape-shifter and genjutsu mistress. So, not too hard to make changes. But I think the BEST person to make changes might be Nawaki.
Because just him being alive would mean so much in terms of Senju presence. And even if he doesn’t have Wood Release (but which I’ve written that he does so…) what his continued existence means for Tsunade and Kushina personally (who can then influence Naruto directly or not). Or what his continued existence might mean for the Uchiha clan… I suppose it’s more a potential of influence than actual influence, I guess.
Konran definitely doesn’t know about canon. Immediately I know she would emotionally handle it the worst, because basically it’s a world in which her twin brother isn’t even a twin or a brother. Here comes an existential crisis. Because she’d emotionally handle it the worst, I’d be reluctant to predict how she’d handle it influentially. Obviously she’s in position to influence Naruto most directly, but will she want to? Will she do so in a positive way? I don’t know.
Emotional Handling – Zakuro. Hands down. I considered Ringo, because of the two Ringo is the “calmer” one, but then I realized: he’s a medic. He’s a taijutsu using medic. He’s as pacifistic and selfless as a shinobi can be. If he did believe the canon knowledge, however he got it, he would view all the deaths in canon and try his best to prevent them and only destroy himself.
Zakuro, in contrast, is a genjutsu and trap specialist. He knows that perception is more important than reality and for all his brash personality, he can be patient. Traps don’t always get sprung–it’s about preparing for possibilities, not getting directly involved. Zakuro wouldn’t lose himself to the knowledge. He’d take it, absorb it, learn from it, adapt.
The only hitch in this is that he wouldn’t want to keep the knowledge a secret from his teammates, but given their personalities, he would have to. So it’s not the knowledge itself that he would have trouble handling.
But to be clear, Zakuro is ony best at emotional handling. He’s not really in a position to make significant enough changes, for all that he has the mindset to do it.
Influential Handling – … the three people who I think could best utilize the knowledge and make changes are also the three people (besides Konran and Naruto) who would emotionally handle the knowledge poorly. Ringo is one of them–because for all he is the same rank as Zakuro, he does have sort of bonds with both Obito, though he doesn’t really know it, and Kakashi, and if he can figure out how to leverage said bonds he can mitigate a lot of suffering on their and everyone’s parts.
The other two are Kakashi and Jiraiya. The reason why I didn’t bring them up in previous series is because the nature of canon vs Counterpoise is a missing Uzumaki child. Minato’s child. And yes, it’s true, that shouldn’t be such a big deal seeing as how they they ignored Naruto in canon. But I wonder how much of that was the Sandaime’s terribad “don’t discuss the Kyuubi even though everyone and their monkey summons know about it” and how much of that was the village plausibly denying Naruto’s heritage.
So DoS brings up how Naruto could have been named Uzumaki because of his jinchuuriki status not because he’s actually related to Kushina. Additionally I’ve read somewhere that some people thought Naruto took Minato’s appearance because the Kyuubi was being deliberately cruel and kitsune are all about shapeshifting (which is why Naruto’s specialty before kage bushin is henge). And also, while I don’t know how canonical this is, there’s the idea floating around that Minato and Kushina kept the pregnancy a secret so enemy villages couldn’t find out and such. So, like, the village could have just been handwaving the obvious connections between Naruto and his parents. And because Kakashi and Jiraiya don’t get involved with him, there’s nothing to contradict that.
But Konran doesn’t have the Kyuubi. Konran has bright red hair and goes by the name Uzumaki. Konran is so undeniably Kushina’s child that there is no handwaving this away. It’s for this reason that I’m kind of playing around with the idea that the Cloud ambassador tried to kidnap Konran in addition to/instead of Hinata (which also explains why Konran becomes so desperate to keep her hair hidden when she’s a genin).
Anyway. That incident and the lack of plausible deniability means that Kakashi and Jiraiya kind of have to get involved and canon knowledge would only help them if they would get off their asses and do something. Don’t get me wrong, love the characters. But they are capable of making great change, they just need a massive shove to do so.
A/N: Uh… that got long and rant-y towards the end. Hopefully this was what you were looking for, lionheadbookends, and if not feel free to send another ask my way 🙂
