What are some interesting plots in 'naruto ancient summon fanfiction'?

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.

One interesting plot could be a rabbit summon that has a special power to heal. In the fanfiction, Naruto could discover this rabbit during a mission in a hidden forest. The rabbit's healing power would be crucial in saving his comrades from a deadly poison.

One interesting plot could be that the serpent summon is actually a key to an ancient ninja treasure. Naruto has to go on a quest with his serpent to find the location of the treasure while fending off other ninjas who also want it.

Maybe in the fanfiction, Naruto is in a situation where he accidentally summons a cobra during a crucial battle. The cobra turns out to be a really powerful and intelligent being. It helps Naruto not only win the battle but also starts to teach him some forgotten ninja arts. For example, the cobra could show Naruto how to use the environment to his advantage in a way that no one has thought of before.

Perhaps the butterfly summon is connected to an ancient prophecy. Naruto is the only one who can summon these special butterflies, and they are meant to help him unlock a new level of power. As he forms a bond with the butterflies, he learns more about the prophecy and his true destiny. The butterflies could also be a symbol of hope in the Naruto world, and their presence could inspire other characters to believe in Naruto's ability to bring peace.

An interesting plot could be that the salamander summon has a connection to an ancient prophecy. Naruto, with his salamander, has to fulfill certain tasks to prevent a great disaster. For instance, they might need to find a lost artifact that is key to maintaining the balance of the ninja world.

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.

Perhaps in the fanfiction, the leviathan is a sentient being from a different dimension. Naruto forms a bond with it not just as a summon but as a friend. They communicate telepathically, and the leviathan helps Naruto understand some of the deeper secrets of chakra by showing him how it manipulates energy in its own dimension.

One interesting concept could be the unique and often dark nature of the summoned creatures. In regular Naruto, summons are somewhat standard, but in dark summon fanfictions, they might be more menacing, like demons with special powers that can corrupt the summoner or the environment around them.

Maybe the Cerberus in the fanfiction has a special connection to the Nine - Tailed Fox. It could be that they are both from an ancient and powerful lineage. The Cerberus could be a guardian of some sort, and its summoning requires the main character to prove their worthiness, perhaps by passing a series of trials in a mysterious realm.
