It could be a rogue member of an old enemy race. Maybe a disgruntled Androssian who has his own plans for galactic domination. He might have new technology or powers that make him a formidable foe to the Star Fox next - gen team.
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.
It could be a rogue member of the Star Fox organization who has turned against them for personal gain. This character might have once been a respected member but became corrupted by power or money.
One idea could be the introduction of new alien species that the Star Fox team has to face. For example, a race of energy - based beings that can manipulate space - time. Another could be a story where the younger generation of the Star Fox team has to prove themselves to the older members. Maybe they get into a difficult mission where their new and untested skills are put to the ultimate test.
The main characters include Captain Jean - Luc Picard. He is the strong and wise leader of the Enterprise. Then there's Commander William Riker, Picard's second - in - command. Data, the android, is also a central figure, always curious about human emotions and behaviors. Dr. Beverly Crusher is another main character, taking care of the medical needs on the ship. And of course, Geordi La Forge, the chief engineer with his special visor that allows him to see in different spectra.
Darth Maul could be a great antagonist. His double - bladed lightsaber would be a formidable weapon against Naruto. Maul's acrobatic fighting style and his Sith powers would pose a huge challenge to Naruto's ninja skills and new - found Jedi powers.
Orochimaru would be a great main antagonist. He's always been interested in power and the secrets of the body. Naruto's half - demon fox nature would be a prime target for his experiments. He could try to extract the power of the demon fox from Naruto, or use Naruto as a way to create his own brand of super - soldiers with demon - like powers.
A powerful organization that wants to use the power of the Fox King for world domination could be the main antagonist. They see Naruto as an obstacle because of his connection to the Fox King. JM, being associated with Naruto, also becomes a target. This organization might have their own set of powerful ninjas and dark jutsu, and they stop at nothing to achieve their goal of harnessing the Fox King's power.
The children of the original characters could be the main ones. For instance, Riley and Lucas's child could be a central character. They would inherit some of their parents' traits but also have their own unique personalities.
The children of Nagisa and Kayano could be main characters. They might inherit some of their parents' skills and quirks. For example, Nagisa's son could have his father's stealthy nature.
Deanna Troi, the ship's counselor, is important as she helps the crew deal with emotional and psychological aspects of their adventures. In crossover novels, these main characters interact with characters from other Star Trek series, which can lead to new relationships and challenges. For instance, they might meet Kirk or Spock from the original series, and these interactions can be both exciting and full of conflict as different leadership styles and values collide.
