Naruto might also be a sort of guardian of the multiverse in the context of the fanfiction. His immortality gives him the time and ability to watch over not just the Young Justice world, but also any threats that might cross over from other universes, including his own Naruto universe. He could be the first line of defense against any villains or threats that could endanger both worlds.
She could be a strategist. With her ninja training, she's used to thinking on her feet and coming up with plans in the heat of battle. Just like she did in the Naruto world against foes like Orochimaru or Pain.
In a Justice League fanfiction, Dark Naruto could be the anti - hero figure. He might not always follow the rules like the other members. His role could be to bring a different perspective on justice. For example, he might be more willing to use extreme measures to stop villains. He could also be the one who has a connection to a different kind of magic or power source that the Justice League has not dealt with before, adding a new layer of mystery and danger.
Susano Naruto in a Young Justice fanfic could be a threat. Imagine if his powers were misused or if he was brainwashed. His Susano form is extremely powerful and could cause a great deal of destruction in the Young Justice setting. The heroes would have to figure out how to stop him without killing him, adding an interesting moral dilemma.
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.
If Naruto were the son of Black Mask in this fanfiction, his powers would blend in an interesting way. His ninjutsu is not like the typical superpowers in Young Justice. His ability to use chakra to perform various jutsus would be a novelty. The Rasengan, for example, could be a very powerful close - range attack. His tree - climbing and water - walking abilities could also be used in creative ways during missions. Maybe he could use his tree - climbing ability to scale tall buildings quickly or use water - walking to cross bodies of water without the need for boats or other means. His powers would offer new strategies and solutions to the challenges the Young Justice team faces.
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.
She is a key player. Her role can be as a strategist, using her sharp mind to plan missions. Just like in the official DC universe, she can analyze situations quickly.
Trunks in Young Justice fanfiction might also bring a sense of mystery. His time - traveling adventures in his own series could lead to some really cool plot twists in the Young Justice story. He could be searching for something or someone in the Young Justice universe, and that search could drive the whole story forward.
Amazo often plays the role of a formidable antagonist in Young Justice fanfiction. His power to replicate the abilities of the heroes makes him a tough enemy to defeat. He can disrupt the status quo of the Young Justice team and force them to reevaluate their combat tactics.
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.
