Pony Head is a character that could be explored more. In fanfic, she could have a backstory about how she became so self - centered and what really happened to her family. It would add depth to her character.
Janna could be another one. There could be fanfics that focus on her own magical adventures that are separate from Star and Marco's. Maybe she has a secret connection to an ancient magic on Earth.
Mr. Harrison, the rather grumpy neighbor. He could be explored more deeply. There could be a backstory about why he's so grumpy and how Anne's presence gradually changes his outlook on life. It would be interesting to see his softer side and how he interacts with the community in a different way.
One underrated character is Prentiss. He's often just in the background in the original, but in fanfiction, he could be the hero. Maybe he discovers a hidden power within himself that helps Peter and the gang. Another is Ted. He could be given more spotlight by having his own backstory explored, like how he ended up on the ship in the first place.
Padma Patil. In the original story, she's sort of in the background. But in a fanfic, she could be a really interesting character. Maybe she has some secret knowledge about the Triwizard Tournament or a special connection to one of the visiting schools. She could play a crucial role in helping Harry or another character navigate the challenges of the tournament.
Xenovia is another underrated character. In future fanfiction, she could play a much bigger role. For instance, she could be the one to discover a new holy sword that has the power to not only slay devils but also has some sort of purification ability that could change the balance between the factions. She could also have a more complex relationship with Issei, not just as a friend or ally but with some romantic undertones.
Rock Lee. He has such a great determination and unique fighting style. In fanfiction, we could explore his journey to become an even greater ninja, perhaps by giving him some new techniques or having him face opponents that really test his limits.
The character of [character name]. In the original trilogy, they were kind of in the background, but in fanfiction, they could be shown to have hidden powers or a really interesting personality. They could be the key to solving a big mystery that the main characters are facing.
Mercy Graves is an underrated character. In a fanfic, she could be developed more as a complex character. Maybe she has her own motives for being involved in Lex Luthor's schemes. She could be the one who has a change of heart and tries to stop Luthor from pitting Batman and Superman against each other, adding a new layer of intrigue to the story.
One underrated character is Tyson. He's Percy's cyclops half - brother. In fanfiction, he could be given more complex storylines, like leading a group of cyclopes in a battle against a new evil force. Another is Silena Beauregard. Her story could be explored more deeply, such as her relationship with the other campers before her sacrifice.
I think Wylie could be one. He has so much potential but often gets overshadowed by the main characters. In fan fiction, his relationship with other characters, like his family ties, could be explored more, and he could be given his own adventures that showcase his unique skills and personality.
Well, obviously the moon and star themselves could be the main characters. They could be personified entities with their own personalities. The moon could be calm and wise, while the star could be more impulsive and energetic.
