Sarada, Sasuke's daughter, is also popular. Her relationship with Boruto, her struggle to master her Sharingan and be as strong as her father are common themes. She is often portrayed as a strong - willed and intelligent character in fanfics.
Boruto is definitely one of the popular characters. As Naruto's son, he has big shoes to fill and his journey to find his own identity while living in his father's shadow is often explored in fanfics.
Scorpius Malfoy is often a popular character. He's the son of Draco Malfoy, and in fanfics, he can be portrayed as a complex character with his own moral struggles, often forming interesting relationships with the children of Harry Potter and his friends.
Lillie is often a popular character. She has a kind heart and her growth throughout the new generation story makes her a great focus for fanfiction. Writers can explore her further adventures and relationships with other characters and Pokemon.
Sarada, Sasuke and Sakura's daughter, is also popular. She's strong - willed and determined to become a great ninja like her father. Her relationship with Boruto and her journey to discover more about her family are often explored in fanfiction.
Definitely Goten and Trunks. They have a lot of room for development in fanfiction. Since they are the sons of two of the most powerful Saiyans, fans like to imagine them achieving even greater power levels. Also, Uub is quite popular. He has the potential to be a very strong character as he is the reincarnation of Majin Buu. Fans are interested in seeing how he fits into the new generation of Dragon Ball stories.
Boruto, of course, is an obvious choice as he is Naruto's son. He already has a lot of development in the official series, but in a fanfic, you could explore his growth in different directions, like if he had to take on a much greater responsibility at a younger age.
Naruto himself is extremely popular. His journey from an outcast to a hero is so inspiring that many fans like to expand on it in fanfiction. They might write about his further adventures, his training with new masters, or his relationships in more detail. Sasuke is also a very popular choice. His complex personality and his path of redemption (or further fall into darkness in some fanfictions) are very interesting to explore.
Scorpius Malfoy is often very popular. He has an interesting backstory as the son of Draco Malfoy and brings a different perspective to the new generation at Hogwarts. His relationship with Albus Potter is also a big draw for many fanfic writers.
In these fanfics, Kakashi could be a popular character. He was Naruto's teacher and now he could be an advisor to Naruto as Hokage. His wisdom and experience would be invaluable. And of course, characters like Shikamaru, who is known for his intelligence, could also be important in helping Naruto govern the village.
Obviously, Naruto himself is the most popular character in toddler Naruto fanfic. But other characters like Iruka - sensei as a kind of protector or mentor figure to toddler Naruto also often appear. Sakura as a toddler friend or rival can also be a popular character in these fanfics.
Naruto himself is extremely popular. His energetic and go - lucky nature lends well to the often - comical and short - form nature of vines. Writers can easily create humorous situations around his determination and his unique ninja skills.
