Perhaps Sarutobi has been suppressing certain clans in the village, causing unrest. Tsunade, being good, steps in to mediate. She tries to bring equality and harmony back to the village. As she does this, Sarutobi tries to stop her by using underhanded tactics. This leads to a series of battles and political struggles between them, with Tsunade ultimately aiming to restore the village to its former glory and fairness.
One plot point could be that Sarutobi has been misusing the village's funds for his own personal gain. Tsunade discovers this and decides to expose him. She then has to fight against Sarutobi's supporters to bring justice to the village.
The main plot could involve Sarutobi secretly training a group of rogue ninjas to carry out his evil plans. Tsunade, as the good character, figures out his scheme. She then has to assemble a team of loyal ninjas to stop Sarutobi and his rogues, while also trying to protect the innocent villagers caught in the crossfire. It could also be about Tsunade trying to reform the village's leadership system that Sarutobi has corrupted.
Perhaps Naruto discovers some long - lost teachings or secrets of Sarutobi and goes on a journey to master them. This could lead to him facing various opponents who also want those secrets for their own evil purposes. He would then have to protect Sarutobi's legacy while also growing as a ninja.
One possible plot point could be Naruto making a big mistake in a battle strategy. For instance, he might underestimate an enemy's strength due to his over - confidence, leading to heavy losses for the village. This would definitely contribute to the view of him being a bad Hokage.
Well, usually Sarutobi being bad might be shown as being power - hungry or making decisions that harm the village in the long run. Tsunade, as good, could be depicted as a healer and a strong leader who tries to fix the mess Sarutobi made. For example, she might use her medical skills to save those affected by Sarutobi's bad policies and lead the village towards a more positive future.
One possibility is that Tsunade is trying to find a way to enhance Naruto's already formidable chakra control. Maybe she's experimenting with new medical - ninjutsu techniques to see if she can make Naruto's body even more resilient in battle. This could lead to Naruto having to endure some painful procedures but ultimately emerging with new powers.
One possible plot development could be Naruto being initially confused about having a maid. He might be a bit shy or not used to someone taking care of him in that way. The maid could also have a mysterious past that gets intertwined with Naruto's own journey. Maybe she has some hidden skills or knowledge that helps Naruto in his ninja training.
One possible motivation could be to create drama. By having Naruto kill Sarutobi, it would shock the readers and create a huge rift in the story's world. It might also be a way to explore Naruto's dark side that we rarely see in the official story.
Another plot development could be that with Sarutobi as his adoptive father, Naruto has access to different mentors. Sarutobi could call in favors from other great ninjas to train Naruto. This would expose Naruto to a wider variety of fighting styles and strategies. Maybe he gets trained by Kakashi earlier, or even has the chance to learn from some of the retired or older ninjas who usually keep to themselves.
A really interesting plot twist could be that the whole concept of 'evil' is a facade. Naruto, as the godson of what is thought to be evil, might find out that Sarutobi was actually in league with this 'evil' all along. They were working together to bring about a new order in the ninja world. But as Naruto grows, he has to decide whether this new order is truly good or just another form of tyranny. He could then use his unique position to either support or oppose Sarutobi and the so - called 'evil'.
If Naruto was adopted by Tsunade in fanfiction, he would probably be exposed to a different set of values. Tsunade is a strong - willed and sometimes reckless woman. Naruto could pick up on her fearless attitude towards battle and also her more practical approach to leadership. Also, their relationship might change the power dynamics in the village a bit, as Naruto would be directly under Tsunade's wing.
One possible plot could be that Tsunade kidnaps Naruto because she believes an enemy is after him and she wants to keep him safe in a secret location. She might think that by taking him away from the village, she can train him without any distractions or threats.
