My Hero Academia Copy Quirk Fanfiction: What Are Some Interesting Plot Ideas?

One idea could be a villain who can steal quirks and is secretly a former hero trainee who was wronged. They start stealing quirks to create a super - powerful army to take revenge on the hero society that failed them.

First, consider their motivation for using the Copy Quirk. Are they using it to become the best hero? Or maybe to prove themselves to someone? For example, if they want to be like their idol hero, they might copy only the quirks of that hero at first. Then, think about the limitations of the quirk. Maybe they can only copy a quirk for a short time, so they have to strategize when to use it. This would force them to study different quirks and opponents carefully.

One cool quirk idea could be 'Shadow Mimicry'. The user can blend into any shadow and move freely within the shadow realm, also being able to mimic the actions of those whose shadows they are in. It gives a lot of stealth and surprise attack possibilities in a fanfiction.

One idea could be Izuku struggling to control his shadow quirk at first. Maybe it has a mind of its own and he has to learn to cooperate with it. For example, in battles, the shadow could act independently, which might cause trouble but also surprise opponents. Another plot could involve Izuku using his shadow quirk to explore hidden or dark places. Since shadows can reach areas that are hard to access, he could use it for rescue missions or to find secrets in the city.

One idea could be that Izuku's quirk is related to time manipulation. He could use it to slow down time during battles, giving him an edge in combat. For example, he could dodge attacks with ease and plan his counter - attacks carefully.

A great plot could be that there is a mystery surrounding the origin of the dragon quirk. Is it related to some ancient power or a genetic experiment? The character sets out on a journey to discover the truth about their quirk. Along the way, they meet other characters with unique quirks and form alliances. They might also encounter villains who want to use their quirk for evil purposes, adding a layer of danger and excitement to the story.

The 'Plant Symbiosis' quirk would be a great addition to a fanfiction. The individual with this quirk can form a symbiotic relationship with plants. They can communicate with plants, make them grow rapidly, and even use plants as an extension of their body for things like creating shields or lashing out at enemies. This quirk could bring a whole new element of nature to the story.

One idea could be a fanfiction where Deku's quirk suddenly mutates. Instead of just having One For All, he starts to develop an additional power related to it, like the ability to share a fraction of One For All's power with his friends temporarily to boost their own quirks in a time of great need.

One idea could be that the OC's voice quirk is a secret weapon against a new type of villain who can't be defeated by normal quirks. The OC has to keep their quirk hidden until the right moment. Another plot could involve the OC's voice quirk being stolen by a villain, and they have to find a way to get it back. Maybe the OC uses their voice to communicate with animals in the My Hero Academia world, and this leads to an adventure where they have to stop a group of villains who are using animals for evil purposes.

One interesting concept could be seeing how characters adapt to new quirks. For example, if Midoriya had Bakugo's Explosion quirk, his usually timid nature might contrast sharply with the aggressive nature of the quirk. He would have to learn to control his emotions in a different way to master it.
