Well, a possible plot is that the lion summons are actually from a different dimension. Naruto accidentally stumbles upon the connection to this dimension and the lion summon contract. As he tries to understand and use this new power, he has to deal with the cultural differences of the lion society in that dimension. They could have their own rules and hierarchies. Another plot could be that the lion summons are the last hope to stop an ancient evil that is rising again. Naruto has to convince the lions to help him and the entire ninja world, which is no easy feat as the lions are initially reluctant.
Well, lions are known for their strength, so their physical attacks would be more powerful than many other summons. They might be able to break through strong defenses more easily. Their sense of smell could be used in a unique way in the Naruto universe. For instance, they could track enemies over long distances. Also, since they are majestic and inspiring creatures, their presence alone could intimidate opponents more than some other summons. And in terms of their abilities, they could have a special type of chakra that is related to their pride and territorial nature, which gives them an edge in battles.
Well, it depends on the specific fanfiction. There are countless Naruto fanfictions out there, and while some might depict Naruto as secretly a summon, others may not touch on this idea at all. It's all about the creativity of the fanfiction authors.
One interesting storyline could be a young ninja who discovers a rare and powerful insect summon. For example, they might find a group of glowing beetles that can create illusions. The ninja then has to learn how to control and use these beetles in battles against other powerful foes in the Naruto universe.
In some Naruto fanfictions, it's possible for Naruto to summon snakes. Fanfiction often takes creative liberties, so writers might give Naruto this ability for the sake of an interesting plot twist or a new power - up. It allows for different storylines to develop, like Naruto using snake - based jutsus or having a connection to snake - related elements in the Naruto universe that he doesn't have in the original series.
He could summon different kinds of tigers. Maybe there are snow tigers for cold environments. These tigers would be white - furred and well - adapted to snowy areas. They could be used in missions in the Land of Snow.
Definitely Pikachu. Since Naruto is often in need of a quick and agile ally, Pikachu's speed and electric attacks would be very useful. Plus, Pikachu's cute appearance but powerful abilities would create an interesting contrast with Naruto's ninja style.
Maybe Jiraiya. Since Jiraiya was Naruto's mentor and taught him a lot of things. He might have some knowledge about summoning kami and pass it on to Naruto.
It could be fire - breathing dragons. Given Naruto's own energetic and passionate nature, fire - breathing dragons would be a fitting match. They could add a new level of destructive power to his arsenal.
Sure. Fanfiction gives a lot of creative freedom. Some fanfic authors might come up with special circumstances or new abilities that enable Naruto to summon the Kyuubi. Maybe he discovers a hidden jutsu or makes a pact in the fan - made - up world of the story. This can make for really interesting reads as it twists the original Naruto story in unexpected ways.
