Well, in such a fanfiction, there could be intense battles. The Justice League, with all their powers and skills, would face the chaotic and unpredictable Joker. Maybe the Joker would come up with some devious plan to outwit the heroes, like using mind - games and his signature tricks.
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.
Well, one possibility could be that Naruto's powerful ninjutsu skills give him an edge. He might use his Shadow Clone Jutsu to confuse the Joker and then land a fatal blow with a Rasengan. Another aspect could be Naruto's strong sense of justice which drives him to take out the chaotic Joker in the Justice League universe.
In the world of the fanfiction, Gotham City would be in shock. The Joker has been a long - standing symbol of chaos there. His death by Naruto could lead to a power vacuum. There could be copycat villains trying to fill the Joker's shoes, or there could be a period of relative peace as the criminal underworld is shaken by his sudden demise. The public's perception of Naruto would also vary. Some might see him as a hero, while others might fear his power.
Wonder Woman could be among the most challenged too. She represents truth and justice in a very different way compared to the others. The Joker's chaotic and amoral nature could really test her beliefs. He might try to undermine her confidence in her own values and make her question the right way to dispense justice, which would be a difficult situation for her to handle.
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.
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.
