One interesting plot development could be Izuku using his new control over One for All to quickly master new quirks within it. He might surprise his classmates and teachers with his rapid progress in combat training.
Perhaps in the fanfic, Izuku's control of One for All allows him to combine different quirks in unique ways. For example, he could use the strength aspect with the speed aspect to create a new fighting style that no one has ever seen before. This would make him a formidable opponent in battles against villains. He may also use his control to transfer some of the power to his friends in times of need, which would be a great display of teamwork and trust.
One interesting plot development could be Izuku unlocking a new power during the fight. This new power gives him an edge and surprises All for One.
He becomes more confident. With the ability to control One for All, Izuku feels more in charge of his power and less like a burden. This new - found confidence shows in his interactions with others.
Well, a cool plot development might be that Naruto uses his ability to control all elements to bring peace to the ninja world in a unique way. He could use earth to rebuild damaged villages, water to provide clean water sources, fire to provide warmth in cold areas, and wind to power mills or something like that. Also, there could be a plot where he has to train a new generation of ninjas in his all - element control techniques, which leads to a whole new set of adventures.
One idea could be Izuku struggling to control the All for One quirk at first. He might accidentally absorb quirks he doesn't want, leading to chaos. For example, he absorbs a quirk that makes him grow extra limbs and has to figure out how to hide it. Another could be that villains target him more, thinking he'll be easy to corrupt with such a powerful quirk.
Well, it depends on the specific fanfic. Some fanfic authors might choose to write a story where Midoriya has a hard time controlling One for All at first, but through various challenges and character development, he gradually gains better control. Others might give him immediate and effortless control for the sake of a different kind of plot. So, there's a wide range of possibilities in fanfics regarding his control of One for All.
Power dynamics. Since Izuku has the All for One power, how he interacts with other characters who have powers is crucial. He could be seen as a threat or a potential ally depending on the story.
One interesting plot twist could be that Izuku initially doesn't know about his father's true identity. He grows up believing he has no quirk and then discovers his father is All For One. Another twist could be that All For One has some hidden motives for fathering Izuku, like using him as a pawn in a bigger scheme against the heroes.
Well, one interesting plot point could be Izuku unlocking a new power specifically to counter All for One. Maybe it's a hidden aspect of One for All that he discovers during the intense battle.
Perhaps Naruto's relationship with the other villagers changes more rapidly. In the original story, they were initially afraid of him because of Kurama. But with all of Kurama sealed in him from the start, they might be more in awe or more fearful, which could lead to different interactions. He might also have a different standing among the ninja in his village, being seen as a more immediate and powerful asset or threat, depending on how they view the power of Kurama.
One interesting plot twist could be that Izuku initially struggles to control the All For One quirk. Since it's a very powerful and complex quirk, he might accidentally absorb quirks from his friends or allies, causing a rift between them. For example, he could absorb Uraraka's zero - gravity quirk and she feels violated. Another plot twist could be that the League of Villains, thinking Izuku is now one of them because of the All For One quirk, try to recruit him. Izuku has to pretend to go along with them to gather intelligence, but it becomes a dangerous game as he risks being corrupted by their ideology.
