The Entire Narutoverse would change. Somethings like:
- Naruto won't be a Jinchuuriki and he would happily live with his parents, Minato and Kushina.
- Itachi would be the new leader of the Uchiha Clan, Sasuke would also be the best Chuunin.
- Naruto in my opinion would be smart like his father, but motor mouthed like his mother lol.
- Uchiha Clan would be happily part of Konoha, without grudge of any kind.
- Nagato would be a healthy Uzumaki still living up till today.
- Akatsuki would never be formed.
But Its good Madara is there, meaning all my favourite characters wouldnt have their powers if it wasnt for him lol
