An underrated character is Cotton. His parrot is always a fun addition, and he could be the focus of a fanfiction. Maybe the story could be about how he lost his tongue and his journey before joining the crew. It would give a new perspective on the story.
Murtogg is another underrated character. He's just a regular sailor, but in a fanfiction, he could be the hero. He could be the one who discovers a way to break the curse that everyone else overlooked. His relationship with Mullroy could also be explored in more depth, and how they both deal with the strange events on the Black Pearl.
Murtogg is another character that could be explored more. He seems to be a bit of a follower, but there could be a story where he has to take charge. Maybe in a situation where the cursed crew is in a new kind of danger and he has to make decisions that go against his usual timid nature. This could show a different side of him and make for an interesting fanfiction.
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 main characters are Captain Jack Sparrow, that flamboyant and unpredictable pirate. Elizabeth Swann, a young woman from a more civilized world who finds herself in the midst of pirate adventures. Then there's Will Turner, a skilled blacksmith with a connection to the pirates. There might also be Barbossa, the captain of the Black Pearl when it's under the curse. He's a formidable and cunning adversary.
The Wasp. She is a powerful and intelligent character. A fanfiction could center around her leadership skills within the Avengers. Maybe she has to lead the team in a situation where all the big - name heroes are incapacitated. It would show her strategic thinking and her ability to inspire others.
The stable hands who take care of the dragons often get overlooked. They have a unique perspective as they interact closely with the dragons on a daily basis. Fanfiction could explore their lives, their dreams, and how they view the dragon riders.
The White Rabbit is often just seen as the one who leads Alice into Wonderland, but he could be so much more in fanfiction. He could be a time - traveler, for example, and his hurry is because he's always on a tight schedule to different eras. The Tweedle brothers are also underrated. They could be the key to unlocking some ancient secrets of Wonderland. In a fanfiction, they could lead Alice on an adventure full of riddles and puzzles that reveal the true nature of Wonderland. And the Caterpillar is quite an interesting character to focus on. It could be a wise sage who holds the knowledge of the entire Wonderland universe.
Shino Aburame is quite underrated. In a fanfiction, he could be shown as a key figure during the Revolution. His unique insect - based jutsu could be developed further, and his calm and intelligent nature could be used to his advantage in the political and social upheaval of the time.
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.
Definitely the Northuldra people in general are underrated as a whole for fanfiction. They have a rich culture that we only got a glimpse of in the movie. Focusing on one of the unnamed Northuldra characters, perhaps a young girl who was there when Elsa first arrived in the forest. She could have her own perspective on the events and her own story of how she saw Elsa as a potential savior or a threat. Also, the guards from Arendelle who were with Mattias could be the focus. Their adjustment to living in the forest for so long and their loyalty to Mattias could be explored in a fanfiction.
