I reworking the Uchiha AU I came up with a few years ago and it got me excited to share it!
First off, all of Madara‘s siblings survive, as well as Itama and Kawarama. Alongside that I want to add Mama Senju. Mama Uchiha sadly passed away already but she’s still deeply loved.
Keeping all the kids (and Butsumas wife) keeps Butsuma and Tajima sane. They aren’t as shitty as they are in canon. Heck, their good dads.
Another thing that keeps Tajima sane with five kids is Sakumo! Sakumo is our first time traveler and him and Tajima hit it off. Uchiha rarely fall in love twice. It’s considered a good omen if they do. Sakumos arrival and relationship with Tajima brings positive change to the Uchiha. The second Sakumo shares he has a son - Kakashi is declared Tajimas son as well. Basically the Uchiha are now missing a member of the main family.
Sometime later the oldest, Tajimas daughter, is kidnapped by bloodline thief’s, how she originally died, luckily for her Obito appeared not far from her. He helps her and gets her home. The Uchiha see this clearly Uchiha child/teen that’s missing an eye (he has an eyepatch covering his rinnegan) and they adopt him. When Sakumo and Tajima arrive at the scene, Tajima hugs his daughter while Sakumo looks and Obito and recognizes him. He asks about Kakashi. Obito doesn’t know where Kakashi is, but he knows Kakashi is there. (Cause sharingan connection)
Obito and Sakumo tell the family stories about Kakashi - the kids (Madara and his siblings) adore Kakashi already. That’s their Kashi-nii! Their eldest brother. Tajima loves the stories too.
Meanwhile the Senju are in a bit of trouble. Itama and Kawarama are about to die the deaths they faced in canon but lucky for them a nice Hatake bin helped them. Kakashi saved them! Kakashi stays with the Senju for a few days as thank you since he’s exhausted. They wanted him to stay but he says he has to find his family again.
While that is happening the twins, Tajimas youngest, run into trouble. Obito is there to save them again but before he finds them he runs into his own little brother, Shisui. They rescue the twins together. (It’s a stupid little headcanon of mine, bear with me)
Sometime later Hashirama and Madara meet. 🤫
While those meetings are happening - Kakashi runs into Tenzou. He found his kohai! That’s one family member found!
Anyway - when the meetings between Madara and Hashirama are interrupted, the whole family is there. Mama Senju is actually Hatake and knows Sakumo is too.
Before it comes to a clash between Tajima and Butsuma they are stopped. Tajima by Mokuton and Butsuma by a blade. Tenzou and Kakashi respectively. Obito is the first one to react and he hugs Kakashi, he pulls Tenzou into the hug too. Then Sakumo hugs all three because that’s his boy. He precious boy and he has a friend. (He’s convinced he and Obito are dating - he’s not wrong)
After that the two clans start to work towards peace a lot sooner than in canon. Konoha will still be founded by the kids, but there be peace and trade between the clans. It actually helps strengthen the bonds between the clans before Konoha is founded. It makes a stronger foundation for Konoha.
