Well, Jimmy Casket might be portrayed as a wild card. He's the kind of character who can go from being friendly one moment to being a bit menacing the next. His personality is full of contradictions. He can be very charming when he wants to be, but also has a short temper. Jonhy Ghost is usually depicted as a more stable personality. He's kind - hearted and often tries to help other ghosts in need. He's patient with Jimmy Casket's antics and tries to guide him to be a better ghost in a way, even though it's not always easy.
One interesting storyline could be their origin stories. Maybe they both come from different spooky realms and meet by chance in a haunted house. Their powers could be different yet complementary, like Jimmy Casket having the ability to possess objects and Jonhy Ghost being able to pass through walls. Another could be a story where they team up to face a greater evil, perhaps a powerful dark sorcerer who is trying to take over their haunted world.
In fan fiction, Diana could be shown as having different relationships. She might be in a romantic relationship with a character not associated with her in the original work. This changes her dynamic and gives new angles to her character. Also, she could be portrayed as more vulnerable or more powerful than in the original, depending on the writer's vision.
Raven is often portrayed as the more reserved one. Her love for Starfire might be shown through small, quiet gestures. She might be protective of Starfire in a very understated way, using her powers to shield her when needed. Starfire, on the other hand, is usually more open and exuberant. Her love for Raven could be expressed through big hugs and lots of positive affirmations.
Often, different personalities are portrayed through changes in character motivation. For example, a fanfic might show Dumbledore as having a more self - serving personality. His actions, like keeping secrets from Harry, could be for his own gain rather than for the greater good. This completely flips the perception of his character from the original series.
Sesshomaru's personality in these fanfics can be shown as a complex mix. He is still the powerful and fearsome demon, but his love for Rin makes him more vulnerable. He may hide his emotions most of the time, but there are moments when his concern for Rin slips through. As for Rin, she is portrayed as a ray of sunshine in Sesshomaru's rather dark world. She is curious, brave in her own way, and her love for Sesshomaru gives her the strength to face many difficulties. She might even be the one to make Sesshomaru see the good in the human world more often.
Adventure can also be a theme. Writers might send Fiona and Jimmy on wild adventures, like traveling to a new and strange place. This could test their relationship and also add an element of excitement to the story. They might face various obstacles during the adventure and have to rely on each other to overcome them, which can be a great way to develop their characters further.
Well, Hermione is a very intelligent and detail - oriented person. Jace, on the other hand, is confident and has a bit of a cocky side. In many fan fictions, their personalities create a lot of interesting dynamics. Hermione can be a bit exasperated by Jace's overconfidence, but at the same time, she respects his skills. Jace, initially, might not understand Hermione's love for books and knowledge, but he soon realizes how valuable it can be. They learn from each other, and their relationship grows as they overcome their differences in personality.
Captain Phasma is often portrayed as a very no - nonsense, disciplined and strategic character. She is loyal to the First Order and is always focused on achieving her missions efficiently. For example, she will plan every detail of an operation meticulously.
Often, Spider Gwen is portrayed as brave and determined. She has the strength to face villains and protect the city. MJ, on the other hand, can be shown as intelligent and sassy. She might be the one to offer clever ideas or witty remarks in their adventures.
Ash is often portrayed as his usual enthusiastic and determined self. He's eager to learn from Sir Aaron and is always ready for a new adventure. His love for Pokémon shines through even more in these fanfictions.
