The plot could be that Raven is in a dire situation in her world. She discovers an ancient spell that might be able to bring a powerful ally to her side. She decides to use it to summon Naruto. Once Naruto arrives, they face a powerful enemy that is threatening Raven's world. They combine their powers, Naruto's Rasengan and Raven's dark magic, to defeat the enemy.
In this fanfic idea, when Minato summons Future Naruto, it could also be for emotional reasons. Minato missed out on seeing Naruto grow up. By summoning Future Naruto, he gets to see the strong and capable man his son has become. Future Naruto can then tell Minato about his life, his friends, and all the adventures he's had, filling Minato with pride.
In this fanfic idea, Naruto summoning Shinigami captains could be really interesting. Maybe he could summon them to help in a battle against a powerful enemy like Kaguya. The Shinigami captains' unique abilities like kido and zanpakuto skills could turn the tide of the fight. Naruto's own chakra reserves and jutsu combined with their powers would create a very different kind of story dynamic.
One possible fanfic could involve Raven using some sort of dark magic or special jutsu to summon Naruto from his own world to hers. Maybe she needs his help to fight off an evil force in her realm that her own powers are insufficient to defeat. Naruto, with his never - give - up attitude and powerful ninjutsu, could bring a new dynamic to Raven's world.
A possible plot could be that there is a disturbance in the balance of the Naruto world. The sages believe that only a being from another realm can help. Naruto is chosen to perform the summoning. He summons Mordred, and at first, they don't get along because of their different backgrounds. But as they learn more about each other and the true nature of the threat, they form an alliance. Mordred teaches Naruto some new combat techniques, and Naruto shows Mordred the value of friendship and loyalty in his world. Eventually, they defeat the enemy and Mordred may or may not decide to stay in the Naruto world depending on how their relationship has developed.
Well, first off, there would be a lot of destruction. Godzilla is huge and his attacks are powerful. The landscape would be changed completely. For example, if he was summoned in the middle of a battle in the Naruto world, he could easily take out large groups of enemies just by stomping around. Also, Naruto would have to deal with the fact that Godzilla is not an ordinary summon. He might not be as easily controllable as other summons. Naruto would have to find a way to communicate with Godzilla, maybe through his chakra or some other means.
One challenge is the power balance. Hollows can be extremely powerful in the Bleach universe, and Naruto has his own set of strong abilities. Combining them in a believable way is tough. Another is the lore. Naruto has its own deep lore, and so does Bleach. Keeping both consistent while merging them is difficult. Also, the character interactions need to be well - thought - out. How will Naruto communicate with the Hollows? What will his friends think of these strange summons?
Naruto would probably be in awe at first. He'd try to communicate with Mothra in his usual friendly and exuberant way. He might start by introducing himself and his village, just like he did with other summons. Then he'd try to understand Mothra's powers and how they can be used to help in battles or protect the village.
The character development in these fanfics can be quite special. Since they are from different worlds, they have to learn about each other's cultures and values. This learning process helps in shaping their characters further, like Naruto might learn about Raven's more somber and mysterious nature, and Raven could be influenced by Naruto's never - give - up attitude.
