If Naruto could summon Manda in fanfic, it would likely change the balance of power in battles. It might also affect his relationships with other characters, as they'd view him differently with such a powerful summon at his disposal.
Well, it could be about Naruto having some special powers or a connection to Manda that changes his journey. Maybe he has to deal with the expectations that come with being related to such a powerful being like Manda. He might face challenges from those who fear or envy his newfound status.
In fanfiction, Naruto's contract with Manda can be really interesting. Sometimes, it might deviate from the original story. Writers could create scenarios where Naruto forms the contract under different circumstances, like in a time - travel plot or an alternate universe. Maybe he has to prove himself in a new way to Manda, not just with strength but also with his understanding of the snake's nature.
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.
Well, in such a fanfiction, Naruto might grow up with a very different set of skills. Manda is a large snake, so Naruto could learn more about stealth and survival in the wild. Maybe he'd be more in tune with nature. He could also develop unique fighting styles inspired by Manda's movements, like quick strikes and coiling maneuvers.
A really cool Naruto Manda fanfiction could be set in an alternate universe where Manda is a more benevolent creature. Naruto discovers this side of Manda and together they work to bring peace between the snake clans and the human villages in the Land of Fire.
A possible plot could be that the rat summons are in danger. Some dark force in the ninja world is hunting them down for their unique chakra or some other special ability they possess. Naruto has to protect his rat summons and in the process, he uncovers a conspiracy that is much larger than he expected, involving multiple villages.
The plot could be that Naruto accidentally summons the leopard instead of his normal toads during a battle. The leopard is initially hostile but Naruto manages to convince it to help him. They then form an unexpected bond and the leopard becomes Naruto's secret weapon.
It could be the people in the village who are against Naruto because of his new identity as the son of Manda. They might see him as a threat to the village's stability.
Well, obviously Naruto and Manda are main characters. Naruto, being the protagonist of the original series, often has his own motives and goals in these fanfictions, like learning new jutsu from Manda or using Manda's power to defeat a stronger foe.
Rock Lee could be an interesting human summon. His extreme dedication to training and unique fighting style would make him a valuable asset in battles. He could be summoned to help Naruto when facing opponents with strong physical abilities.
