In fanfiction, their daughter could have a complex personality. She might be a bit of an introvert, preferring to read and study on her own, much like Lydia. But at the same time, she could have Stiles' loyalty to her friends. She'd be the type to always be there for her friends in times of need, and she might use her intelligence to help them out of tricky situations.
Well, considering Stiles was always curious and into solving mysteries, their daughter might have a very inquisitive personality. She could be constantly asking questions and eager to learn new things. And from Lydia, she could get a bit of sassiness, not afraid to speak her mind when she needs to.
She could be really intelligent like Lydia. Since Lydia was known for her smarts in the show, their daughter might inherit that and be a top student. Maybe she'd also have Stiles' sense of humor, always cracking jokes and making people laugh.
She might be a sort of mediator between different supernatural groups. Since Stiles was good at making connections and Lydia had her own status in the supernatural world, their daughter could use those advantages. She could be the one to bring peace when there are conflicts between werewolves, banshees, and other creatures.
Well, considering her parents, she might have a bit of a rebellious streak. Since Draco was from a traditional pure - blood family and Hermione was a Muggle - born witch, their daughter could be defiant against the old - fashioned pure - blood ideologies. She could be very outspoken and not afraid to challenge the status quo in the wizarding world. And she'd likely be very empathetic too, having seen different sides of the wizarding community through her parents.
Perhaps they find out they're pregnant unexpectedly. Stiles starts making all these plans for their future as a family right away. Lydia is more cautious, thinking about how this will change their lives completely. Their friends could also play a big role, some being super supportive while others might be skeptical. And they could have to deal with family reactions, like Stiles' dad being really excited and Lydia's parents having mixed feelings.
Well, she could be highly intelligent like Hermione. Maybe she'd be a bookworm, always with her nose in a tome, eager to learn new spells and knowledge. At the same time, she might inherit Draco's sense of pride. So she'd be confident in her abilities and not easily intimidated. However, she could also have a kind heart, a blend of Hermione's compassion and Draco's loyalty to his own, which in this case would be his family.
She could be strong - willed like Naruto. He has always been determined in the face of difficulties, and their daughter might inherit that. And from Kurenai, she could get her intelligence and calmness. Kurenai is a smart kunoichi, and their daughter might be able to think clearly in tough situations.
Her personality might be a mix of her parents'. She would have Naruto's sense of humor and his ability to make friends easily. This would help her in forming alliances with other ninjas. At the same time, she would inherit Tenten's determination. When she sets a goal, she would be relentless in achieving it. For instance, if she wants to master a new weapon technique, she would keep practicing until she gets it right, just like Tenten with her weapons training, but she would also make the training process fun with her Naruto - like humor.
It could also be an unseen force controlling Theo. In this case, the real antagonist is this hidden entity that uses Theo to kidnap Lydia. The story could then be about Lydia and her friends not only rescuing her from Theo but also uncovering and defeating this greater threat.
There's a fanfic called 'Stiles and Lydia: A New Beginning'. In this story, they start anew in a different town away from all the chaos. It's really refreshing to see them build a normal life together while still having that underlying supernatural connection. Also, 'Lydia's Choice' is good. It focuses on Lydia having to make some tough decisions regarding her relationship with Stiles and how it affects their future together.
There's also 'Kiss in the Moonlight' which has a really romantic setting for their kiss. The story uses the night - time and the moon as a backdrop to enhance the mood of their relationship development and the kiss itself. It's quite popular among fans.
The theme of redemption can also be found in some 'dark stiles and lydia fanfiction'. Maybe one of them has made a mistake or has been involved in something bad in the past, and they are trying to make up for it. This makes their characters more complex and the relationship more interesting as they grow and change together while dealing with the dark elements in the story.
