The Kraken summon can fit in many ways. It could be a new discovery in some hidden scroll, leading a character to try and master the summoning jutsu for it. This discovery could be accidental or the result of a long - search. For instance, Naruto might stumble upon it while exploring an ancient ruin. It would then become a part of his arsenal, and he'd have to learn how to work with this massive and powerful creature.
Another way the Kraken summon fits into Naruto fanfiction is through the idea of a dark or forbidden summoning. It could be that summoning the Kraken is considered taboo because of its uncontrollable power. However, a rogue ninja or an antagonist might attempt to summon it in order to cause chaos. This would then force the heroes, like Naruto and his friends, to either stop the summoning or find a way to control the Kraken if it is successfully summoned, creating a high - stakes and exciting plotline.
In Naruto fanfiction, the Kraken summon can be a really cool and unique addition. It could potentially be a very powerful summon, perhaps even more so than some of the traditional ones like toads or snakes. Maybe it has special abilities like being able to control water on a massive scale or having tentacles that can crush opponents. Writers might use it to give Naruto or other characters a new edge in battles, making the fight scenes more exciting and unpredictable.
The crocodile summon could be the result of a genetic experiment in the Naruto universe. Maybe some rogue ninja was trying to create a new type of summon and the crocodile was the outcome. Naruto then has to deal with the consequences of this experiment as he tries to control the crocodile. He also has to figure out how to use the crocodile's abilities, which might include things like camouflage in water and enhanced speed in wet environments.
In some fanfictions, Naruto might summon Kurama through a new and special jutsu. For example, he could use a jutsu that combines his own chakra with the unique bond he has with Kurama. This jutsu might be created during a time of great need, like when facing an extremely powerful enemy that normal attacks can't defeat.
Well, in some fanfictions, Naruto might be able to summon Rashomon through some special training or a unique power-up. Maybe he discovers a hidden jutsu scroll that teaches him the method of summoning this powerful gate.
It varies from one fanfiction to another. Some might write that he uses a special hand sign or a chant. For example, he could make a unique hand sign and call out the name of the fairy he wants to summon.
In some fanfictions, Naruto might gain the ability to summon zombies through dark magic or a forbidden jutsu he discovers. Maybe he stumbles upon an ancient scroll that teaches him this unorthodox summoning technique.
Often, it combines them through crossovers. For example, a portal could open between the Naruto universe and Shinji's world, allowing characters to travel between them.
Another way Cerberus can fit into the Naruto world in fanfiction is as a spiritual guide. Maybe Naruto, during a near - death experience, enters a spiritual realm where he meets Cerberus. Cerberus then guides him on a journey to discover new powers within himself. This could be related to Naruto's connection with the nine - tailed fox and how Cerberus helps him better understand and control that power.
In some fanfictions, it could be through a special magical incantation or a powerful magical artifact. Maybe she discovers an ancient spell book that has a spell specifically designed to cross different fictional universes and summon entities like Kyuubi Naruto.
Futanari characters can blend into the Bleach and Sakura fanfiction universes by interacting with the original characters. They can form alliances, rivalries, or even romantic relationships. In Bleach, they might team up with Ichigo and his friends, and in Sakura's world, they could interact with Sakura and her companions, thus becoming an integral part of the story.
