They have very different quirks. Fumikage's Dark Shadow quirk and Tsuyu's Frog quirk are unique, and in fanfiction, it's exciting to see how these powers can interact or be used in combination during battles or other situations.
One great fanfiction could be 'Shadows and Frogs' which explores their relationship during a joint training mission. It delves into how Fumikage's reserved nature contrasts with Tsuyu's more straightforward personality. The story shows their growth as they learn from each other's strengths and weaknesses.
One common theme is friendship development. Writers often explore how Midoriya and Tsuyu's friendship grows over time, like through shared experiences at UA. Another theme is mutual support. For example, Midoriya might support Tsuyu when she's facing difficulties with her quirk or self - confidence, and Tsuyu does the same for Midoriya when he's doubting himself.
Start with his internal struggle. Fumikage is often haunted by the power of Dark Shadow. Show how he gradually accepts this part of himself more. For example, at the beginning, he might be afraid to fully use Dark Shadow's power in case it gets out of control. But as the story progresses, he learns to trust himself more.
They can start with simple acts of kindness towards each other. For example, Deku could offer to help Tsuyu with her studies, especially in hero theory, which he's good at. Tsuyu, in turn, could share her insights on how to better use one's quirk in real - life situations. This mutual exchange of help can gradually build their connection.
Another good one is 'The Izuku - Tsuyu Team - Up'. In this fanfiction, they are paired up for a hero exercise that goes awry. The story is filled with action and also some really sweet moments between the two characters. It shows how they support each other and grow as heroes together.
One great example could be 'A Green and Froppy Adventure'. It shows Deku and Tsuyu on a joint mission where they have to rely on each other's unique quirks. Tsuyu's frog - like abilities combined with Deku's newfound power make for an exciting story.
One idea could be Fumikage exploring a new power within his Dark Shadow. Maybe he discovers a way to temporarily split Dark Shadow into multiple entities, each with a different ability. For example, one could be super fast while another could have enhanced strength.
One idea could be that Tsuyu and Deku are paired up for a special hero training mission in a dangerous, uncharted area. They have to rely on each other's unique quirks to survive and in the process, they develop a deeper bond. Another could be a story where Tsuyu discovers Deku's self - doubts and helps him overcome them with her calm and practical nature.
In these fanfictions, a significant theme is the exploration of their personalities. Tsuyu's calm and collected nature compared to Momo's more studious and sometimes self - doubting personality can create interesting dynamics. Fanfictions may delve into how they complement each other. Additionally, some fanfictions have a theme of mystery - solving. They might be put in a situation where they have to use their wits and quirks together to solve a mystery within the 'My Hero Academia' universe.
