There could be a fanfiction where Naruto gets his multiple summoning contracts through a special training with different sage regions. He first trains with the toad sages and then discovers a new sage region where he is offered a contract with magical deer. These deer can run at super - fast speeds and can carry Naruto and his team across long distances quickly, which is very useful during missions.
In some fanfictions, Naruto's multiple summoning contracts might be a result of some ancient prophecy. For example, he might be able to summon both phoenixes and serpents. The phoenixes could be used for their healing powers and the serpents for stealth attacks, making his combat strategies much more diverse and unpredictable.
One could be a fanfiction where Naruto discovers he has the ability to summon not just toads but also other powerful creatures like wolves from a hidden contract. This new power gives him an edge in battles and changes the way his enemies view him.
A great one is 'Naruto: The Multi - Summoner'. In this fanfiction, Naruto unlocks the secrets of multiple summoning contracts one by one. It starts with his toad contract and then he discovers a contract with elemental spirits that help him control different types of nature chakra more effectively.
Well, having all the summoning contracts might also be a burden. He has to manage and keep good relations with all the different summon clans. If he fails to do so, he could lose their support. Also, it might be overwhelming to keep track of all the different summons' abilities and needs.
There could be a fanfiction in which Naruto's scars are magically inflicted by a dark sorcerer. These scars hold a curse that Naruto has to overcome. This could lead to a journey where he searches for a way to break the curse, all while still trying to protect the village. It would be full of action and self - discovery.
One possible fanfiction could be where Naruto's horns are a result of some ancient curse or power awakening. Maybe he has to learn to control this new aspect of himself while still dealing with his regular ninja duties.
One interesting concept could be the unique combinations of summons. For example, a character might be able to summon both fire - based and water - based creatures simultaneously, leading to new and unexpected battle strategies. Another concept could be the origin and history of these multiple summoning contracts, perhaps they were created by an ancient shinobi who had mastered different elements.
Fanfictions that feature crossovers are also quite popular. For instance, a Naruto and One Piece crossover can bring together two very different but equally exciting worlds. Writers can play with the unique abilities of characters from both series. These crossovers often attract a large following as they offer a fresh take on the Naruto story by incorporating elements from another well - loved franchise.
Another idea for a fanfiction is that the lyrium tattoos are part of a prophecy. Naruto, being the main character, is the chosen one to bear these tattoos. His friends might be initially skeptical or worried about the strange markings. But as the story progresses, they realize the tattoos are the key to saving the ninja world from a new, powerful threat.
In some fanfictions, Naruto's genjutsu bloodline might be a result of some hidden experiment. This could lead to a lot of internal conflict in him as he tries to understand how he got this power. He might struggle with the idea that he was experimented on, but at the same time, he uses the newfound genjutsu abilities to protect his friends and the village. He could develop genjutsu that can manipulate the emotions of his opponents, making them feel fear or doubt.
Naruto having all the summoning contracts would mean he has access to a vast array of resources. He could use the unique abilities of different summons to gain an edge in battles. For instance, if he needed to cross a large body of water quickly, he could summon a water - based creature. And in combat, he could combine the attacks of different summons to create powerful and unexpected strategies, which would greatly alter the power dynamics in the story.
Well, 'Naruto's Expanded Summoning' is a great one too. In this story, Naruto accidentally unlocks the ability to have multiple summons during a battle. His new summons, which include some rare and powerful creatures, help him turn the tide of many battles. It also delves into how he manages to train and bond with all these different summons at the same time.
