In most cases, it's not appropriate. Fan - created works should be accessible to a wide range of audiences, including younger fans. All Might is a well - known and respected character, and creating explicit content around him in the form of fanfiction goes against the general spirit of the fandom. However, if the 'lemon' is just a misnomer and it's actually a clean story about the relationship between All Might and an OC, then it could be okay.
Well, the relationship development can be complex. The OC, due to their abuse, might be initially distrustful of All Might. But All Might's consistent kindness and protection start to break down those barriers. They could have heart - to - heart conversations where the OC shares their traumas, and All Might shares his own insecurities (despite being a hero). This mutual sharing of vulnerabilities can bring them closer together. Also, the OC might start to mimic All Might's heroic behavior, which further cements their relationship as they grow together in the story.
One popular trope is the 'Mentor - Protégé' relationship. The OC could be a new hero in training and All Might becomes their mentor. Another is the 'Power Transfer' trope where the OC might receive some of All Might's power in an unexpected way.
Well, Reddit can also be a good place. There are some subreddits dedicated to My Hero Academia fanfiction. You could post a request asking for All Might and OC fanfictions. People are usually helpful and might direct you to some great works. Also, Tumblr sometimes has posts about such fanfictions. You can search relevant tags like #AllMight #OC #Fanfiction.
One great 'all might x oc fanfiction' is 'A New Hope'. It has a really interesting OC who has unique powers and an engaging relationship with All Might. The story is full of action and character development.
Some All Might x Abused OC fanfictions explore the emotional abuse aspect. The OC might be emotionally scarred from past experiences, like being constantly belittled. All Might enters their life and with his positive attitude and unwavering belief in people, he slowly helps the OC break free from the chains of that emotional abuse. This can be really interesting as it shows how his character can have a profound impact on someone in need.
You can try searching on some fanfiction websites like Archive of Our Own (AO3). They usually have a wide variety of fanfictions including those with specific pairings like All Might and OC. However, make sure to abide by the website's terms and conditions.
One idea could be that the OC discovers All Might in his feral state and tries to help him regain his humanity. Maybe the OC has a special power that can soothe his wild nature. For example, the OC's power could be related to nature, like the ability to communicate with animals. They use this power to connect with All Might on a deeper level and slowly bring him back to his normal self.
Start with an encounter that creates a strong initial reaction. For example, if the OC is a healer, they might be drawn to the injured feral All Might out of compassion. This initial meeting can be the spark that begins their relationship. Then, have them interact in small ways at first, like sharing food or shelter if they are in a dangerous situation. These simple interactions can build trust over time.
