What are some interesting plot ideas for Danzo Shimura crossover fanfiction?

Naruto himself would be an interesting addition. His ideals of friendship and forgiveness could be in direct contrast to Danzo's more underhanded and secretive ways. It would create a lot of tension and potential for character growth for both of them.

You could write a fanfiction where Tenko Shimura is transported to an alternate universe where heroes and villains have different roles. In this universe, he might be forced to team up with heroes to survive. This would give a chance to explore his character in a new light, as he has to adapt to new rules and relationships while still dealing with his own inner demons.

One plot idea could be that Kushina and Danzo have to work together to protect the village from a powerful outside threat. They start off distrusting each other, but as they face challenges, they gradually learn to respect and rely on one another.

One idea could be that the good elders finally see Danzo's true nature and work to expose his dark deeds secretly. They might team up with Naruto, who has always been suspicious of Danzo. For example, they could start by gathering evidence of his illegal experiments in the Root. Another plot could be that a good elder uses his influence to rehabilitate the Uchiha clan's reputation, which Danzo had a hand in ruining, and Naruto helps in this process by using his charisma among the villagers.

Maybe a crossover with a magical anime. The nanbaka characters could suddenly find themselves in a world full of magic. Some of the nanbaka characters might be really good at using magic in unexpected ways, like Jyugo using his shackles in a magical battle.

A crossover with a modern - day action story could be really cool too. Spartacus and his crew could be brought to the present day through some time - travel mishap. They then have to navigate the modern world, learning about new weapons and technology. They could use their ancient fighting techniques in modern combat situations, like taking on a powerful criminal organization.

Maybe in the fanfiction, the three - tailed beast crosses over into a modern - day human world. People initially fear it, but then they discover that it has a gentle side and is actually trying to find its way back home. It could form a bond with a group of humans who help it on its journey, leading to many adventures along the way.

One idea could be a crossover with 'Fullmetal Alchemist'. Dorohedoro's dark and gritty world combined with the alchemical concepts would be fascinating. For example, the characters from Dorohedoro could be exposed to the laws of equivalent exchange. Another plot could involve a crossover with 'Hunter x Hunter'. The nen abilities in 'Hunter x Hunter' could interact in strange ways with the magic in Dorohedoro's world. Maybe a character from Dorohedoro has to participate in the Hunter Exam. A third idea is a crossover with 'Tokyo Ghoul'. The idea of the ghouls' existence in Dorohedoro's setting and how they would coexist or clash with the existing creatures and characters there.

One idea could be a Vegito crossover with the Dragon Ball GT universe. Vegito could face off against the Shadow Dragons, creating an epic battle of power. Another could be a crossover with the One Piece world, where Vegito has to navigate the Grand Line and deal with pirates. Maybe he teams up with the Straw Hats to take on a common enemy.

One idea could be a crossover with the 'Indiana Jones' series. The Mummy's curse could somehow be related to an ancient artifact that Indiana Jones is after. Maybe they have to team up to stop the mummy from unleashing a greater evil.
