Well, there are several out there. In some of these fanfictions, Stiles' transformation into a fox often leads to him discovering new abilities. For example, in a particular story, he finds out he can communicate with other forest animals in his fox form. This adds a whole new layer to the story as he uses this ability to help his friends. The change also affects his relationships, especially with his best friend. There's a lot of character development that can come from such a transformation in fanfiction.
One popular one might be 'Tails' New Form' where the transformation is a result of a magical mishap. It delves into how Tails, now as a girl, adjusts to the new body and the reactions of her friends in the Sonic universe. It's a really interesting take on the character and has some great character development moments.
One popular fanfiction with this premise is 'The Young Alchemist'. It's really interesting as it explores how Edward, now as a kid, has to deal with his past knowledge and skills while having a child's body. It also delves into his relationships, like how his brother Alphonse reacts to this new situation.
There's a fanfic titled 'Jurdan's Little Miracle'. It focuses on how Jurdan's relationship evolves during the pregnancy. It has some really heart - warming scenes where they discuss their hopes and fears for their future family. It's quite a popular one among fans of the pairing.
There might be a fanfiction where Lucy's pregnancy is part of a magical or science - fictional plot. For example, if it's in a fantasy world, the unborn child could have some special powers that are gradually revealed during the pregnancy, leading to a series of adventures and challenges for Lucy.
One great fanfiction could be 'The Abduction of Stiles'. In this story, Stiles is kidnapped by a mysterious group. The author does a wonderful job of building suspense as his friends race against time to find him. It has some really intense moments and great character development.
I recall a fanfic titled 'Sickly England'. It focuses on how England's sickness affects his magical abilities. He's unable to control the weather around his area as well as he usually does. Some of the younger nations, like Sealand, try to cheer him up with their childish antics, which is really cute in the story.
There's a fanfic titled 'James Potter's Trial by Injury'. Here, James is injured in a dark magic encounter. This story focuses on how he battles not only his physical pain but also the mental turmoil of potentially not being able to use magic again. It shows his growth and determination in the face of such a huge setback.
There are fanfictions where Artemis is kidnapped by fairies who have finally had enough of his meddling in their world. They take him to their realm and he has to use his wits to escape while also trying to understand their culture better. It's a really cool concept that combines the mystery of the fairy world with the tension of a kidnapping situation.
There's a fanfiction called 'Our Big Day'. In this, Quinn and Santana's wedding is full of heart - warming moments. It shows their relationship in a very real and emotional way, with all the little details of the wedding planning and their feelings towards each other.
There's a fanfic called 'Zuko and Katara: United in Marriage'. In this story, their marriage is not just about their love for each other but also a symbol of unity between the Fire Nation and the Water Tribe. It has some really heartwarming scenes of them sharing their cultures with each other. Well, I also like 'Zuko & Katara: A Married Adventure' which is full of exciting adventures they embark on as a married couple.
