Often, there is the theme of inspiration. Deku is very inspiring in the original story, and in fanfiction, he can inspire Shoto to be a better hero. Also, self - discovery. They both are on a journey to discover more about themselves, their powers, and their place in the hero world. In fanfiction, this journey can be elaborated on in different and interesting ways.
One common theme is redemption. Dabi, with his troubled past, often has a journey towards redemption, and Shoto can play a part in that. Another theme is family. Given their complex family relationships in the original story, fanfics often explore how they deal with family issues together.
No, it is not appropriate. Creating or distributing sexual fanfiction involving underage or fictional characters in a sexual context is unethical and often violates the terms of use of various platforms. Such content can also be considered a form of inappropriate objectification.
Well, 'shoto todoroki abused fanfiction' might be centered around the idea of taking the character Shoto Todoroki from the original source material and putting him in an abusive context. This could be physical, emotional, or psychological abuse. Some writers may use this as a means to develop the character further, to show his strength in overcoming such difficult situations, or it could be a way to delve into the darker sides of the fictional world in which he exists. It could also be a form of expressing the writer's own creativity and interpretation of the character's potential experiences.
Adventure can be a common theme as well. The female character and Shoto might go on quests or face challenges together. This could be related to Shoto's hero training or some external threat. Through these adventures, their relationship deepens and they learn more about each other. It's a way to add excitement and action to the story while still focusing on their relationship.
Well, the theme of inspiration is quite common. Shoto can get inspired by his friends, his battles, or even just the world around him. And many fanfics also touch on the theme of breaking free from expectations. He's expected to be a hero, but through art, he can be something different, and fanfics like to explore that.
One popular trope is the 'study buddies' trope. Since Momo is very smart, she could help Shoto with his studies, especially in areas where he might struggle, like theory - based hero knowledge. Another is the 'saving each other' trope. In a dangerous situation, Shoto might use his powers to save Momo, or vice versa, which then deepens their connection. And there's also the 'slow - burn romance' trope, where their feelings for each other develop gradually over time through small interactions and shared experiences.
