A common plotline in Naruto story summoner fanfiction is the discovery of a new type of summoning technique. For instance, instead of using blood to summon, a character might develop a way to summon using chakra signatures. This could lead to some really unique summons, like shadow - based creatures that can manipulate darkness. Another plot could be a summoner who is shunned by their village because their summons are considered 'evil' but they later prove that their summons can be used for good. There might also be a story where a summoner's summons start to disobey due to an external force tampering with the summoning bond, and the summoner has to find a way to fix it.
Another plotline could be that Naruto discovers he has a connection to an ancient and powerful clan that was thought to be extinct. This new connection could bring him new allies, new jutsu, and a whole new set of challenges as he tries to balance his loyalty to Konoha with his newfound heritage.
One idea could be that the summoner has to learn how to control the hydra's multiple heads which all have different personalities. For example, one head could be aggressive and always want to attack, while another is more cautious.
