A third common theme is the use of darkness for good. Despite having a power that is often associated with evil, Izuku tries to use it for the greater good. He may face challenges and temptations to use it in a more negative way, but he resists and instead finds ways to use his darkness manipulation to protect others and fight against true evil in the story. This theme adds depth to the character and the overall narrative of the fanfiction.
There's a fanfiction called 'Shadowed Izuku' in the realm of 'izuku darkness manipulation fanfiction'. In this one, Izuku not only has to deal with the challenges of controlling his power but also faces the prejudice from society who fear his dark abilities. It's a really interesting take on the concept.
One possible plot could be Izuku discovers his energy manipulation quirk has a unique side - it can interact with different dimensions' energy. He accidentally opens a small rift during a training session. This leads to a series of events where he has to learn to control his quirk better to close the rift before it causes chaos. He teams up with his classmates, using their quirks in combination with his to stabilize the rift.
The unique power concept. Blood manipulation is not a common power in the original series, so seeing Izuku with such a power makes for an interesting read. It allows for creative battles and problem - solving.
Izuku could develop in terms of his relationships. His energy manipulation quirk makes him stand out more. Some people may be jealous, while others are in awe. He has to learn to deal with these different reactions. He may form closer bonds with those who support him and his quirk development. At the same time, he tries to understand the ones who are jealous and convert them into friends or at least neutral parties. This process of handling relationships matures his character.
His relationship with All Might would also be affected. All Might might be more cautious about Izuku's quirk as it's very powerful and could potentially disrupt the fabric of time. Izuku, on the other hand, could use his quirk to go back and learn more about All Might's past, which could strengthen their bond as he gains a deeper understanding of his mentor. However, it could also create a rift if Izuku discovers something in the past that he doesn't like about All Might's actions.
Well, 'Izuku's Blood Manipulation Ascent' is another great one. This fanfic not only focuses on his blood manipulation powers but also on his relationships with other characters. It shows how his friends and teachers react to his new powers, and how he uses them in a way that is both heroic and strategic.
Some of the teachers at U.A. might also be antagonists. They could be secretly working for an organization that wants to control Izuku's powers for their own evil purposes. They would pretend to be helpful while actually setting traps and spreading misinformation about him.
Another interesting concept could be that Izuku's 'prince of darkness' status is a hereditary thing that has been hidden from him all his life. When it starts to manifest, he has to deal with not only the physical changes but also the political intrigue within the world of dark powers, where different factions either want to use him or destroy him.
One idea could be that Izuku discovers his time manipulation quirk late. For example, during a really tough battle against a powerful villain where all seems lost. He accidentally activates the quirk and rewinds time just enough to change the outcome. This could lead to a whole new arc of him training to control this powerful and dangerous quirk.
