#if a shinobi found mental imbalance unattractive they'd never date another shinobi.

:( its sad nobody does aus where izuna comes around on the concept of the village and then madara still eventually leaves it and izuna stays behind. like izuna is famously stubborn so i think if you've written him as actually being convinced that Konoha is worth it, he'll stick it out to an insane degree. that includes staying even if madara leaves.

i could imagine him becoming the second hokage, partially out of people respecting his commitment to the cause after his brother abandoned it. honestly you could even get interesting with tobirama in this version of it because you have a lot of canon paths to go down with this. Izuna picking Konoha over Madara would firmly place him in the same mental space as Itachi or Kagami to Tobirama ("he chose the village over X and thus is a wonderful shinobi who i respect") leading to an overly respectful tobirama, which would completely alter his legacy. like you as the reader might know hes kind of insane about the uchiha but the village would just see him dutifully supporting an uchiha hokage.

Alternatively Tobirama's deep seated issues with Izuna specifically could make it difficult for him to see Izuna in that way and he could have a total crash out, ruining his legacy (lol) and slotting him in the same historical space as madara, ironically.

OR third option, he's weird about Izuna but also cautiously supportive, so he's just like a really helpful assistant to him who happens to constantly be checking Izuna for signs of what he considers mental degradation. Izuna is either slowly poisoning him or slowly sowing political rumors about him, either way he's putting in the effort to keep tobirama weak enough (mentally/politically) that he can't do anything against him but is also still around to assist because he is a useful second. I think in this version Izuna would pick Kagami as his heir, both because Kagami is the best trained for it and because Izuna would ensure power remains with the Uchiha, but also somewhat because Tobirama cannot argue against it (Thats HIS student) but wouldn't have picked him first out of all his students (As we know canonically).

this would mean during canon when all the hokage are brought back tobirama isn't and Izuna is, which would do a lot to the plot but this post is long enough so im leaving it there. immovable force vs unstoppable object izuna vs madara essentially
