Ser Davos Seaworth is often overlooked in some aspects. He has a great backstory and a strong moral compass. A fanfic could explore his early days as a smuggler more in - depth, or what he would do if he had to make a choice between his loyalty to Stannis and a new opportunity that could benefit the common people more. And then there's Bronn. He's always been in the background for the most part. A fanfic could put him in a situation where he has to decide whether to stay a sellsword or take on a more noble role, perhaps by taking over a small holdfast and ruling it in his own rough - and - tumble way.
Hot Pie. He may seem like a minor character, but he has a lot of potential. A fanfiction could explore his life after leaving Arya. Maybe he becomes a famous baker in a large city, and through his bakery, he gets involved in the political intrigues of the city as people from all classes come to his establishment.
Hot Pie is an underrated character. He could be the focus in a fanfiction where his baking skills become more than just a side note. Maybe he bakes special treats that have magical or medicinal properties and gets caught up in the big political and power struggles because of it.
Gendry is quite an underrated character. He has the blood of a king in him, being Robert Baratheon's bastard. In fanfiction, he could be explored more in - depth. He could rise up and claim his birthright, or he could use his skills as a smith to create powerful weapons for different factions. Another is Ser Davos. He's a loyal and smart man, but often overlooked. Fanfiction could show him in more complex political situations, using his wits to navigate through the power plays in King's Landing.
Hot Pie is a character that could be really interesting. He's just a simple baker's boy, but he has his own dreams and fears. You could write about his adventures after leaving Arya, how he tries to make a name for himself with his baking skills in different parts of Westeros. Another one is Podrick Payne. He has shown loyalty and courage, and a fanfic could explore his growth from a young squire to a more confident knight - like figure.
Blister is an underrated character. He has a unique look and his skills as a duelist could be explored more in a fanfic. Maybe a story could be written about his past, how he got into dueling, and what his goals are outside of the main events in the show. He could be given more depth and a more complex backstory, perhaps he has a family that he is trying to support through his dueling career.
Gauche Adlai is another underrated character. His Mirror Magic is really interesting. A fanfic could center around him and his relationship with his sister. Maybe he goes on a journey to find a way to completely bring his sister back to life, and in the process, he discovers new aspects of his magic that he didn't know before. He could also face some moral dilemmas about using his magic in extreme ways for his sister.
The guards at the Manyuu clan's gates are often overlooked. They are in a unique position, being the first line of defense and having to deal with all kinds of people coming and going. A fanfic could focus on their daily lives, the challenges they face, and how they interact with the more important members of the clan. Also, there's that one quiet librarian in the clan's library. She has access to all the ancient scrolls and books. A story could be written about her discovery of a long - forgotten prophecy that could change the fate of the Manyuu clan and how she decides to act on it.
Another underrated character is Kenshin Himura from Rurouni Kenshin. His vow to not kill again while still being a powerful swordsman could create interesting moral dilemmas in a Jump Force fanfic. He could interact with other characters who have different views on combat and justice.
Marco is quite underrated. He was smart and had a lot of potential. In a fanfiction, you could explore what would have happened if he had survived. He could have been a great strategist for the Scouts and his relationship with Jean could have been developed further. Another is Hitch. She seems lazy at first but there could be more to her. A fanfiction could show her hidden strengths and how she could contribute to the fight against Titans in unexpected ways.
Yusuke is another underrated character. In a post - game fanfiction, he could be traveling around to find new inspiration for his art. Along the way, he might encounter some Shadows that are related to the concept of beauty in a way that challenges his views. This would not only give him more character depth but also show how his Persona abilities are still relevant outside of the main game's plot.
