Maybe there's a nosy neighbor in the fanfic. This neighbor could be constantly prying into Serena's pregnancy, offering unwanted advice or just being a general nuisance. And don't forget about any pets Serena might have. They could add a cute and funny element to the story, like the family dog being protective of Serena during her pregnancy.
Her partner would be a very likely character to be involved. They could be the source of support, or in some cases, the source of conflict if they have different views on the pregnancy. Her best friends are also likely to be in the fanfic. They might be there to throw baby showers, give advice, or just be a shoulder to cry on.
If Serena has a family, her parents or siblings could be involved. Her mother could be the one giving her old - fashioned pregnancy advice, while her sister might be jealous or overly excited. Also, a doctor or a midwife could be an important character. They would be the ones guiding Serena through her pregnancy, doing the check - ups and answering her medical questions.
Definitely Ash, as he's the center of Serena's affections. But also, there could be new female characters created specifically for the fanfiction. These new characters might be trainers who are really good at Pokemon battles and catch Ash's attention. Serena would then become jealous of their skills and the attention Ash gives them. Additionally, any of Ash's Pokemon that seem to have a special connection with another character could also be part of the scenario that makes Serena jealous. For example, if Pikachu seems to like a new girl more than Serena, that could be a reason for her jealousy.
Professor Sycamore could be a character involved in a surprising way. Maybe he discovers something about Ash that he believes is dangerous and tries to use Serena to stop Ash. Or perhaps there's a misunderstanding where Serena thinks she's doing the right thing by following the professor's orders which seem to go against Ash. It shows how complex the relationships can be in these fanfiction scenarios.
There are several characters that would work well. Lillie from the Alola region could be a great addition. She has her own unique story and relationship with Pokemon that could contrast with Serena's. Another option is Kiawe. His fiery personality could create some interesting dynamics with Serena. Then there's Gladion, who could bring an element of mystery and a different approach to Pokemon battles. And of course, Professor Oak. His wisdom and knowledge of Pokemon could be a valuable asset in a Serena Pokemon fanfic. He could be the one who sends Serena on a special mission or gives her some crucial information about a rare Pokemon.
Tatsumi is very likely to be involved as he has a significant relationship with Esdeath in the original story. Her subordinates in the Jaegers might also be part of the fanfic. They could be shown as being protective or having mixed feelings about her pregnancy.
Another possible main character could be a rival trainer. Maybe someone who has been in the Pokemon world for a long time and initially looks down on Serena. But as Serena progresses, they develop a mutual respect. Also, a Pokemon professor, like Professor Oak, could be in the story. He could provide Serena with valuable knowledge about Pokemon, such as how to catch and train them.
A rival character would be very likely. This could be someone who believes they are more worthy of the throne. They might try to undermine Serena at every turn, creating a lot of conflict in the story.
I think May could be a great character to include. She was one of Ash's good friends on his journey. She could visit Ash and Serena's family and share her experiences from her own Pokémon adventures. Dawn is another option. Her skills in Pokémon contests could inspire Serena's children if they have an interest in that area. And Clemont, with his scientific knowledge about Pokémon, could be a fun addition, perhaps inventing new things for the family's Pokémon." "Answer3": "Professor Oak would be an excellent character to add. He has always been a mentor to Ash. In the fanfiction, he could be the one who gives Ash and Serena's children their first Pokémon or offer wisdom about the history of Pokémon. Also, Gary Oak could be included. His rivalry with Ash could be transferred in a fun way to their children. For example, Gary could challenge Ash and Serena's kids to friendly Pokémon battles, which would add some excitement to the story.
Also, any friends that Renesmee has made throughout her life could be involved. They might be there to offer moral support, or there could be some who are jealous or envious of her situation, which could add some drama to the fanfic.
The Lone Wanderer is likely to be involved. They have a pre - existing relationship with Amata from the game. Her father, the Overseer, might also play a role, either in supporting or opposing the situation. Other characters from Megaton or Tenpenny Tower could potentially be involved as well.
Finn could be involved if the fanfiction wants to explore a relationship with him as the possible father. He was an important part of Rachel's life in the original series, and his reaction to the news would be significant.
