In such a fanfiction, they might team up to fight a powerful new villain. For example, a super - intelligent alien who plans to take over the Earth. The Justice League could initially be skeptical of Supergirl, but as they see her powers in action, they come to respect her.
The Flash might initially be in denial. He's used to Batman always having a plan and his death would be a huge shock. He would then turn his speed into a tool for investigation, trying to find out exactly what happened. Green Lantern could feel a sense of loss but also be spurred into action, using his ring to try and prevent future tragedies like Batman's death. He might create constructs in Batman's memory to inspire the team.
The character dynamics could be complex. Supergirl, being new to the Justice League scene, would be the outsider. She'd be trying to fit in while also maintaining her own identity. Superman would be torn between his loyalty to the League and his family connection to Supergirl. And the other members like Cyborg and Martian Manhunter would be observing, trying to figure out where she stands in the grand scheme of things. This could lead to a lot of interesting interactions, from friendly banter to tense standoffs.
One idea could be that an ancient, powerful enemy emerges that the Justice League alone can't handle. Supergirl, with her unique Kryptonian powers and different perspective, joins them. She might introduce some Kryptonian technology or fighting techniques that give them an edge. For example, she could have a device that can neutralize the enemy's energy - based attacks.
The plot in a 'Justice League Unlimited Oc Fanfic' can be really diverse. It might introduce new characters (OCs) with unique powers and backstories. These OCs could interact with the existing Justice League members in various ways. For example, an OC with telepathic abilities might help the League in a battle against a mind - controlling villain. The fanfic could also explore different relationships among the characters, both old and new. It might show how the OCs adapt to the world of the Justice League and how they are received by the established heroes.
The interaction between Superman and Supergirl would be really interesting. They share the same Kryptonian heritage but have had different experiences on Earth. Superman could act as a mentor to Supergirl, or they could have a friendly competition to see who is stronger in different situations.
In 'justice league unlimited oc fanfiction', the theme of identity crisis is often seen. The OCs are new characters in an established universe, so they struggle with their identity. Another theme is the struggle against prejudice. Since they are original characters, sometimes the other superheroes in the Justice League are prejudiced against them at first. And the theme of growth is also prevalent as the OCs develop their skills and personalities throughout the story.
In my opinion, the most memorable characters in a 'Justice League Unlimited Oc Fanfic' are often those that have complex backstories. For example, an OC who was once a villain but turned good. Their internal struggle between their former evil ways and their new - found heroism is fascinating to read. Also, an OC with the power of invisibility who uses it not just for sneaking around but also to understand the other characters better without being noticed can be quite memorable.
The most interesting element is the power mash - up. Naruto characters have chakra - based powers like jutsus, and Justice League members have superpowers. Combining these, like seeing Flash race against Naruto in his super - speed mode, is really exciting. Also, the clash of ideologies. The concept of justice in the Justice League and the shinobi way in Naruto can lead to great character debates and development in fanfictions.
Power - how Naruto's ninja powers compare and contrast with the superpowers of the Justice League members. For example, Naruto's Rasengan vs Superman's heat vision. This theme of power comparison and how they can work together is often explored in these fan fictions. Another theme is friendship. Just like in the Naruto series, friendship plays a big role. Naruto might form strong bonds with the Justice League members and they all work together to overcome challenges.
