He could be a new character entirely, created specifically for this fanfiction. Maybe he's a powerful mage who has been living in seclusion but now has to step out to help the Young Justice due to some prophecy.
The plot might revolve around Naruto Jade's dad having a past connection to one of the villains in the Young Justice universe. As he tries to protect his family and the world, he has to confront this old enemy. He could also bring in some of the Naruto - like elements, such as unique jutsu or a strong sense of honor, which could influence the way the Young Justice team operates.
He could be a mentor figure. Given Naruto's experience and growth in his own world, he could guide the Young Justice members in their personal and superhero development.
Well, if Naruto Jade were in Young Justice fanfiction, the story could be very different. Naruto's ninja skills and his never - give - up attitude would bring a new dynamic. For example, he could teach the Young Justice team some unique ninja techniques, like shadow clones. This would change the way they approach battles and training. Also, Naruto's backstory of being an outcast at first in his own village could make him bond with some of the Young Justice members who might have similar experiences.
In this type of fanfiction, magic could play a role in character development. For Naruto, experiencing a different type of power system like magic in the Young Justice world could make him question his own ninja way. He might start to adapt some of the magic concepts into his own fighting style. And for the Young Justice characters, learning about Naruto's 'magic' (chakra) could open their eyes to new ways of thinking about power and how to use it more effectively.
Well, it could be about his dad's early life. Maybe he was a great ninja in his youth, trained under a famous master. His adventures during his training days, like facing tough opponents and learning unique jutsus, could be part of the story.
In a Young Justice fanfiction, Naruto's Sage Mode could change the power dynamics significantly. His Sage Mode gives him access to nature energy, which could interact in strange ways with the various powers and technologies in the Young Justice world. For example, his ability to blend into nature while in Sage Mode might make him an excellent spy or infiltrator. Plus, his battle experience and strategic thinking from the Naruto world could help the Young Justice team in their missions.
Naruto would be a bit of a wild card at first. His brash and head - strong nature might clash with some of the more reserved members of the Young Justice team, like Aqualad. But his determination and loyalty would also be something that the team could quickly come to respect. He would probably befriend Superboy quickly as they both have a bit of an outsider feel.
One idea could be a crossover where a character from Young Justice gains the Rinnegan somehow. Maybe through a strange experiment gone wrong that links dimensions. They then have to figure out how to control its powers while still being part of their team in Young Justice. It could lead to some interesting power - up moments and new story arcs.
A group of bandits who operate near the village could also be enemies. They might target Naruto Jade's dad because he is a threat to their illegal activities. They could try to ambush him or attack the village to get to him.
