One possible fanfiction could involve Naruto being transported to the Young Justice universe and somehow getting connected to the Speed Force. Maybe he gains super - speed abilities and has to learn how to control them while also dealing with the threats in the Young Justice world. He could team up with the Young Justice characters, like Robin or Kid Flash, and use his ninja skills along with his new speed powers to take on villains.
The Speed Force in Young Justice fanfiction can also be a source of conflict. Maybe the Speed Force starts acting erratically and causing problems in the world. The Young Justice team has to figure out what's wrong with it. Is it being manipulated by a villain? Or is it a natural imbalance? This could lead to a complex and exciting storyline as they search for answers and try to restore the Speed Force to its normal state.
Naruto could fit in by having his own unique take on the Speed Force. Maybe his 'Nine - Tails' chakra gives him a special connection to it. He could use his speed to perform his ninja techniques even more effectively, like using Rasengan at high speeds. And he could form bonds with the Young Justice characters based on his shared sense of justice.
A common theme is the origin of speed powers. Writers like to come up with unique ways for characters to get connected to the Speed Force. It could be through some ancient artifact or a scientific experiment gone wrong.
Well, he would be super fast, for sure. He could zip around the battlefield so quickly that his enemies wouldn't be able to keep up. He might be able to use his new speed to perform his jutsu even more effectively, like hitting multiple targets in an instant with a Rasengan.
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.
Ruby would be a likely candidate. She's already known for her speed and agility in combat. If she were to be affected by the Speed Force, it would enhance her existing abilities to a whole new level. She could move so fast that she becomes almost invisible to her enemies, and her scythe attacks would be even more deadly with the added momentum.
Peter Parker in the context of the Speed Force could be really interesting. The Speed Force is often associated with speedsters like The Flash. If Peter Parker were to be connected to it, perhaps he could gain super - speed in addition to his spider - powers. This could make him even more formidable in fighting crime in New York. He could use his speed to quickly web up villains or reach the scene of a crime in an instant.
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.
A fanfiction about Naruto and Batgirl in the Young Justice setting could explore different themes. It could be about cultural exchange, as Naruto comes from a very different world than the DC universe. Their combined efforts could also be centered around protecting the innocent. Maybe they have to stop a powerful villain who is threatening both the ninja world Naruto comes from and the Young Justice world. Their different abilities would be crucial in this fight, with Naruto using his Rasengan and Batgirl using her Batarangs and martial arts skills.
