There's also a fanfic series on Archive of Our Own called 'Our Little Family'. It not only shows the adoption process but also delves into their daily lives afterwards. The characters are well - rounded, and the story has a great mix of emotional moments, like when the little sibling has nightmares and the brother comforts them, and light - hearted ones, like their family outings.
I really like the fanfic 'Brother's Promise'. In this story, the brother has to fight through a lot of legal and social obstacles to adopt his little sibling. It's a heart - warming tale that shows the strength of their relationship. The author does a great job of creating realistic characters and situations.
It often explores deep emotions. The little sibling might be scared or confused, and the brother has to be strong but also gentle. For example, in many such fanfictions, the little one might have trouble adjusting to a new home, and seeing how the brother helps is really touching.
One popular 'Vampire Older Sister x Little Brother' fanfiction is 'Eternal Bond'. It has an interesting plot where the vampire sister protects her human brother from the dark vampire world. The relationship between them is complex, filled with love and sacrifice.
Create interesting characters. Give the siblings distinct personalities. For example, one could be shy and the other outgoing. This contrast can lead to many engaging interactions. Also, add some conflict, like the adopted sibling having trouble fitting in at first.
There's a fanfiction called 'Sisterly Bonds'. In this story, the little sister discovers her powers while trying to protect Supergirl. It's full of action and also delves into their sisterly love.
There are quite a few good 'Naruto Little Hokage' fanfictions. One popular one is 'The Young Hokage's Ascent'. It focuses on Naruto's early days as a young Hokage, dealing with political intrigue within the village while still being his goofy self. Another great one is 'Naruto: Little Hokage, Big Dreams' which shows his struggles and triumphs in rebuilding Konoha after the war.
One important thing is to handle the family dynamic sensitively. Since it involves an adoption within the family, you need to think about how the characters will react and adjust. Another aspect is to stay true to the original source material if it's based on an existing franchise. Also, you should focus on character development, like showing how the adopted sibling relationship grows over time.
One interesting Naruto as a little kid fanfiction could be 'The Young Ninja's Adventure'. It shows Naruto's early days in the academy, his struggles with loneliness and how he still managed to be full of energy. It's a heartwarming read that really captures the essence of his character at that young age.
I've heard of a fanfic where Sakura and Sasori are siblings and it delved into their backstory. It explained how they came to be separated and then reunited. The story focused on Sakura's attempts to bring out the good in Sasori, despite his past actions as a villain. It was really interesting to see how their relationship developed in this different context.
One great fanfiction in this genre might be 'The Dragon - Raised Brother'. It shows a really interesting take on how Hiccup's brother, who was raised by dragons, adapts to human society again. The story is full of adventure as he tries to find his place among the Vikings while still having a special bond with the dragons.
One great fanfiction could be where Madara's brother plays a crucial role in preventing the Uchiha massacre. He might secretly work with Itachi to expose the real plotters in the village, thus saving the Uchiha clan. This kind of story gives a new perspective on the Uchiha's situation and shows how things could have been different if he had been more involved.
