Perhaps some of the Hogwarts professors would also be main characters. Professor Dumbledore, for example, would surely be interested in this new family connection of Harry's. He might keep an eye on how Ducky's presence or influence affects Harry's development as a wizard. And Professor McGonagall could also play a role, maybe trying to ensure that Harry's studies at Hogwarts are not disrupted by whatever is going on with Ducky.
There could be Hermione and Ron. Since they are Harry's best friends in the original series, they would likely be important characters in this fanfiction too. They might be curious about Ducky and his relationship with Harry, and could even get involved in some of the adventures that are related to Ducky's past or his influence on Harry.
Well, it could influence the plot in many ways. Maybe Ducky, being Harry's uncle, has some unique magical knowledge or abilities that he passes on to Harry. This could help Harry in his battles against Voldemort. For example, Ducky might know some ancient spells that are not taught at Hogwarts, and these spells could give Harry an edge in dangerous situations.
Abby and Ducky are the central figures. Abby might be depicted with bright colors and a big personality. Ducky could be a bit smaller in size but with a big heart, and together they form the core of the fanfiction stories, whether it's a story about exploring new places or dealing with problems in their little world.
Littlefoot would be a great character to pair with Ducky. They have a strong friendship in the original series, and their different personalities can create interesting interactions. Spike could also be a good pairing. His quiet nature contrasts with Ducky's more talkative and curious self.
If it's a typical ducky story, the main character would be the duck, of course. There might also be other animals like fish in the pond where the duck lives, or perhaps a friendly frog that gives the duck some advice.
Dumbledore could still play a role, perhaps as a mentor from the shadows. Even though he's no longer alive in the original series, in fanfiction, his wisdom could be passed on through memories or portraits. He might offer cryptic advice to Harry about how to use his new power for the greater good and avoid the temptations that often come with lordship.
Well, clearly the main characters are Ducky and Chomper. Ducky is often known for her kind and gentle nature, and Chomper, despite being a different type of dinosaur, has his own unique charm. In this fanfiction, they are the ones at the center of the story, with their pregnancy being the main focus.
Hermione could be one of the main characters. She would be very helpful with all her knowledge of spells and magic theory. She could assist Harry in planning the layout of the village and ensuring that everything is in order.
Hermione could be a main character. She might be initially skeptical about Harry singing muggle music, but then she gets interested in the cultural aspect of it and starts researching the history of the muggle music Harry likes.
There could be an original character who is a descendant of the Uchiha that somehow ends up in the wizarding world. This character could teach fem Harry Potter about the Uchiha ways. Also, Dumbledore could play a role as he always encourages Harry's exploration of different knowledge, and he might be curious about the Uchiha knowledge that Harry is so interested in.
Yes, in some fanfictions, there could be a creative plot where Harry Potter is made to be Jethro's nephew. Fanfiction often takes the liberty of creating such unexpected family relationships to explore new storylines and character dynamics.
