His quirk could be something like super - speed regeneration. In the original Naruto series, he has a great deal of stamina and the ability to heal relatively fast. But with this quirk, he could recover from even the most severe injuries in seconds. This would mean he could keep fighting no matter how badly he was hurt, and his enemies would find it extremely difficult to defeat him.
One plot idea could be focusing on Froppy's journey through pregnancy. Maybe she discovers she's pregnant unexpectedly and has to deal with the initial shock while still being a hero in training. She might struggle to balance her training and the physical and emotional changes of pregnancy.
Often, there are plotlines where Froppy and Deku are in a sort of mentorship relationship in reverse. Froppy, with her calm and collected nature, helps Deku deal with the stress of being the symbol of hope. They might have heart - to - heart conversations about their insecurities and how to face the challenges of being heroes. And there are also stories where they discover a new combined move using Deku's strength and Froppy's agility and sticking abilities.
One way is through self - sacrifice. If the character uses their evil quirk to save a lot of people at great personal cost, it could be a step towards redemption. For example, if their quirk is something like mind - control and they use it to stop a powerful villain who is about to destroy a city, but in the process they lose their own ability to use the quirk. Another way is by showing remorse and actively trying to make up for their past actions. They could start doing volunteer work in the community, using whatever skills they have (even if related to their quirk in a non - evil way) to help others.
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.
