Mitsuki, an artificial human created by Orochimaru, is another interesting character in 2nd generation fanfiction. His loyalties are sometimes questioned, and his unique abilities and his connection to Orochimaru make for some really engaging storylines.
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.
One popular character is Boruto, of course. He is the son of Naruto and has his own story arc in the second - generation fanfiction. Another is Sarada, Sasuke and Sakura's daughter. Her combination of Sasuke's Sharingan potential and Sakura's medical and combat skills makes her an interesting character. And Mitsuki, Orochimaru's creation, is also quite popular as he has a unique background and abilities.
Boruto is an obvious choice. He is the main character of the new generation. Sarada, with her Sharingan and strong - willed personality, is also very popular. Mitsuki, being Orochimaru's creation, has a lot of mystery around him and is a great character to include. Then there's also Cho - Cho, who provides some comedic relief while also being a capable kunoichi.
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.
Sarada is a very popular character to include. She has her own goals of becoming Hokage and her Sharingan gives her a lot of potential for interesting storylines. For example, she could be on a mission to unlock new powers of her Sharingan.
A plot could revolve around the second - generation characters going on a journey to discover the true history of their parents' generation. They could unearth secrets that were long buried and this knowledge could help them in their own battles and relationships. Maybe they find out about a secret alliance their parents had and have to decide whether to continue it or not.
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.
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.
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.
One popular character is Damian Wayne. As Batman's son, he often plays a significant role in the next - generation stories. He brings his own unique skills and a complex personality, having been trained by the League of Assassins. Another is Terry McGinnis from 'Batman Beyond'. He represents a future version of Batman and has his own set of challenges and relationships. Also, Cassandra Cain, with her exceptional martial arts skills, can be a prominent figure in these fanfictions, perhaps taking on a mentoring role for the new heroes.
Scorpius Malfoy is really popular. He's often depicted as a complex character, not just following in his father's footsteps but forging his own path. His friendship or rivalry with Albus Potter is a common theme.
