Perhaps Naruto starts to have strange dreams or visions related to the phoenix's past or its powers. These could guide him in unlocking new abilities or understanding the nature of the power he has consumed.
One possibility is that Naruto's body begins to change. He might start to show physical characteristics of a phoenix, like fiery - colored hair or eyes that glow like embers. This could cause some confusion or even fear among his friends at first, but as he learns to control the new power, they come to accept it. And he could use these new features to his advantage in battles, like being able to fly or emit intense heat.
Well, it could symbolize a huge power boost for Naruto. Phoenixes in many fictional settings are associated with great power, regeneration, and immortality. Maybe by eating it, Naruto gains some of these abilities, like the ability to heal rapidly or gain a new form of chakra.
He might get really confused. Fanfic often has different interpretations and storylines that can be quite far from the original. Naruto could end up with a jumbled view of his own world and relationships.
Well, one possible plot development could be Naruto joining the ANBU to seek revenge for Asuma's death. He might use the ANBU's resources and training to become stronger and hunt down those responsible.
Another plot development might be that Konoha asks Naruto to train the next generation of ninjas. Naruto, being the hero of the village, has a lot of skills and knowledge to pass on. He might face challenges in training the newbies, like dealing with their different personalities and abilities, but in the end, he manages to create a strong new generation for Konoha.
One possible plot could be that Naruto is sent to the Terminator world through some kind of magic or portal. He then has to use his ninja skills to survive among the Terminators. Maybe he teams up with the human resistance and teaches them some of his ninja techniques to fight back.
The plot might involve the members of team 13 having unique abilities that set them apart from other teams. For example, they could have a special jutsu that they need to master together. And their journey could be about proving themselves to the other ninja in the village. They might start off as underdogs but grow stronger as the story progresses. They could also get involved in some political intrigue within the Hidden Leaf Village, as they are trying to complete their missions and rise in rank.
In a 'Naruto is a Phoenix Devil' fanfic, the plot could involve Naruto being transformed into a Phoenix Devil through some kind of magical or cursed event. This new form could bring internal struggles as he tries to control the devilish instincts while still holding onto his ninja values. He might also have to face off against other powerful entities in the ninja world who see his new power as a threat.
One possible plot could be that Naruto and Ino are on a mission together. During the mission, they face a dangerous situation that makes them realize their true feelings for each other. As they narrowly escape the danger, Naruto impulsively kisses Ino, and from there, they have to figure out how to deal with their new - found feelings while still maintaining their ninja duties.
Maybe Naruto has discovered a new powerful jutsu that Kakashi isn't aware of. This gives him an edge in the fight and he manages to defeat Kakashi.
In a 'Marry Me' Naruto fanfic, the plot could center around a time - travel scenario. A modern - day girl somehow gets transported into the Naruto universe and falls in love with Kakashi. She decides to break all the norms and says'marry me' to him. This would then involve her trying to fit into the ninja world, dealing with Kakashi's initial shock and disbelief, and the two of them facing various challenges together as they explore their new relationship.
