One common theme is self - discovery. In both 'Naruto' and 'Descendants' fanfiction, characters often go on a journey to find out who they really are. For example, Naruto in many fanfics discovers new powers within himself as he tries to understand his place in the ninja world. In 'Descendants' fanfiction, characters from the Isle of the Lost might find out they have more good in them than they thought.
One common theme is legacy. It's about how Naruto's actions and values are passed down to his descendants. Another is the new challenges they face in a changing world. For example, new threats to the villages or different political situations.
They might watch it for the fun of seeing different interpretations of the story and characters. Fanfiction often takes the original plot and characters in new and unexpected directions, which can be really exciting.
Sure. One popular 'Naruto' fanfiction is 'A New Path' which gives an interesting alternate story for Naruto. As for 'Descendants' fanfiction, 'Descendants: Isle of the Lost Reimagined' is quite good. It explores the backstories of the characters in a new light.
One possible main character could be Boruto's son or daughter. They would inherit Boruto's strong ninja skills and have their own unique personalities. Another could be Sarada's descendant, who might have a combination of the Sharingan and some new, unexpected power. And of course, there could be a descendant of Mitsuki, with his unique snake - like abilities and calm demeanor.
One idea could be a crossover with the 'Dragon Ball' universe. Naruto's descendants could team up with Goku's family to fight a common enemy. Another could be a crossover with 'One Piece', where they sail the Grand Line together in search of a powerful treasure that could change both their worlds. Or perhaps a crossover with 'Bleach', and they battle Hollows and Soul Reapers together in the afterlife.
In fanfiction, their descendants could have combined powers. Since Naruto has the Nine - Tails' chakra, and if Naruko has something special, their kids might be able to merge those powers in unexpected ways. Maybe they could create a new jutsu that combines the strength of both Naruto and Naruko's abilities, like a super - powered wind - fire jutsu.
That really depends on personal taste. Some popular ones often involve the characters going on new adventures outside of the movie plot. For example, there might be fanfiction where Mal and Evie have to face a new villain in Auradon.
One idea could be a character from Naruto ending up in the Descendants' world. For example, Naruto himself could be transported there. He might use his ninja skills to deal with the challenges in the Descendants' world, like facing off against the villains in a very different way compared to the Descendants' characters. Maybe he'd use his shadow clone jutsu to confuse the bad guys or his Rasengan to take on powerful foes.
In terms of speed, characters like Sasuke from Naruto are extremely fast. If combined with the agility of a Descendants character like Evie, they could perform some amazing acrobatic feats. Evie could use her knowledge of potions and such to enhance Sasuke's Sharingan abilities further. Maybe she could create a potion that makes the Sharingan more perceptive or gives it the ability to see through certain types of magic.
