Develop their relationships. Maybe one child has a really close bond with their mother or father, and this affects their decisions. Or they could have rivalries or strong friendships with other characters in the fanfiction. Their relationships can drive the plot forward. Also, consider their powers and how they use them. If one has the power of invisibility but is shy, they might use it in different ways compared to a more outgoing child with the same power.
First, give them distinct personalities. For example, one of Danny's future children could be really brave and impulsive, always ready to jump into action, while another could be more cautious and intellectual, thinking things through. You can also show their growth over time, like how they learn from their mistakes in battles or interactions with others.
Think about their backstories. What was it like for them growing up as half - ghosts? Were they bullied at school because of their powers? Or were they celebrated? Their past experiences will shape who they are in the present of the fanfiction. You can also introduce new elements to their backstories, like a special encounter with an ancient ghost that left a mark on them, influencing their character development.
Don't be afraid to give them flaws. A character who is too perfect is boring. Let them make mistakes. For instance, a future kid might accidentally use their powers in public and have to deal with the consequences. This can add depth and realism to their character and make the story more engaging.
Another interesting idea is that Danny's future children are born with a special connection to the human world and the ghost zone. They can act as ambassadors between the two realms, trying to bring peace and understanding. But there are those in both worlds who oppose this idea, creating conflict and drama for the story.
Start with their physical appearance. Give the twin a distinct look, like different - colored hair or eyes. For example, if Danny has blue eyes, the twin could have green. Then, think about their backstory. Maybe the twin was exposed to a different type of ectoplasm when they were young, which affected their powers and personality. If Danny's powers came from an accident in the lab, the twin's could have been a result of a natural ectoplasmic event in the Ghost Zone.
The main characters would obviously be Danny and Sam. Danny, with his ghost - fighting abilities as Danny Phantom, is a key figure. He can fly, become invisible, and has super strength among other powers. Sam, on the other hand, is Danny's strong - willed and intelligent friend. She is often the voice of reason and also has a deep knowledge of the supernatural which helps in their adventures.
Writers often start by giving the future children a distinct personality trait. For example, if the child is Naruto's son, he might inherit Naruto's determination but also have a more calm and collected side from his mother. They also develop their appearance, maybe giving them Naruto's blond hair but with different colored eyes. Another way is by showing their relationships with other characters early on. If they're shy around new people but open up quickly to family friends, that tells a lot about them.
In the lead - up to the wedding, they would have to work through a lot of issues together. Sam might help Danny come to terms with his role as a half - ghost in a more positive way. And Danny would support Sam in dealing with her family's concerns. This would strengthen their bond and make their relationship more mature and stable for the wedding and beyond.
It can develop in various ways. It might start as a hostile relationship, with Dash bullying Danny as usual. But as the story progresses, they could find themselves in a situation where they need to cooperate, like when facing a powerful ghost. This shared experience can gradually turn their relationship into one of mutual respect.
Often, in fanfiction, conflicts play a big role in their relationship development. Maybe there's a new character who is interested in Danny and Sam gets jealous. This jealousy makes her realize her true feelings for Danny. And Danny, in turn, sees how much Sam cares and his feelings for her intensify. It's a common trope that helps to move their relationship forward.
Perhaps their relationship develops in a way that they become more like partners in crime. They could use the Christmas chaos to their advantage. For example, if there's a mean - spirited Christmas spirit causing trouble in town, they work together to stop it. Danny uses his powers and Sam uses her wits and knowledge, and this shared experience makes their relationship grow in a new and exciting way.
Their relationship could develop as they face challenges together. For example, if a new type of ghost - eating plant appears in town, Sam's knowledge of plants and Danny's ghost - fighting skills would make them a great team. Through working together to deal with this threat, they would grow closer and start to trust each other more deeply.
