Well, the plot could start with Naruto being raised in the Joker's lair, completely unaware of his true potential as a ninja. As he grows older, he starts to notice the differences between himself and the other villains around him. He might discover his connection to the Naruto universe, perhaps through some strange dreams or visions. Then, he decides to break free from the Joker's influence and journey back to his own world, or he might try to change Gotham into a better place using his unique skills and values.
One possible plot could be that Naruto grows up in Gotham instead of the Hidden Leaf Village. He would be exposed to the Joker's madness and chaos from an early age. However, his inborn ninja spirit might make him want to fight against the Joker's evil ways and bring some kind of order to Gotham, using his ninja skills in a very different and challenging environment.
In this 'naruto son of joker fanfiction', perhaps Naruto discovers his relation to the Joker later in life. This could lead to a whole new set of challenges. He might struggle with his identity, as he is known for his heroic nature in the original Naruto series. His friends could be confused or even a bit scared of him at first. And he would have to find a way to balance his new - found heritage with his existing values.
I haven't come across a 'Naruto is the Joker's son' fanfiction specifically. However, if it were to exist, it would likely involve a lot of creative and perhaps even absurd concepts. Naruto's values of friendship, hard work and his ninja way would be in extreme contrast to the Joker's chaotic and malevolent nature. Maybe the fanfiction would explore how Naruto, despite his 'father' being the Joker, would still strive to be a hero in a world that is suddenly much darker and more unpredictable.
Well, Naruto is the main character by default in 'naruto son of joker fanfiction'. However, other main characters could be the Hokage at that time. The Hokage would be in a difficult position as Naruto is now related to a very different kind of character. Additionally, new characters created specifically for this fanfiction could be main characters. They could be hybrids of Naruto's world and the Joker's world, with unique abilities and personalities that drive the story forward.
Well, it could be about Harry having the chaotic and unpredictable nature of the Joker as his 'father' in this fanfic world. Maybe he uses some of the Joker's unorthodox tactics in the wizarding world, causing a stir among the witches and wizards. He might have a very different approach to dealing with Voldemort compared to the original story.
In this fanfiction, perhaps Harry's identity as the Joker's son makes him an outcast in the wizarding world. The story could revolve around him trying to prove that he's not just a product of his 'father's' evil. He could use his Joker - like cunning and unpredictability to outwit his enemies in Hogwarts, who might be prejudiced against him due to his strange heritage.
The plot could start with Naruto being disillusioned with the shinobi world. He might see the hypocrisy and the never - ending cycle of war. This leads him to embrace the Joker's ideology of chaos. He could start by targeting the political figures in the Hidden Leaf, causing unrest. His friends would be shocked and try to stop him, but he would be too far gone.
One possible plot could be that the Joker discovers a way to travel between universes and ends up in the Naruto world. He decides to target Konoha because it seems like a place full of order that he wants to disrupt. Naruto and Hinata notice the strange new presence in the village. They initially underestimate the Joker, but as he starts causing mayhem, they realize they need to combine their skills to stop him.
If Naruto is like Joker in fanfiction, the plot could develop in a way that Naruto starts to create his own brand of 'justice' which is very different from what the ninja world is used to. He might target corrupt ninja leaders or those who abuse their power. This would lead to a lot of chasing and hiding, as the ninja establishment would see him as a threat. His friends would be divided in their opinions about him - some might support his new ways, while others would oppose him.
Well, it could be that Naruto, with his ninja skills, sees the Joker causing chaos in his world which has somehow merged with the DC universe. He might use his Rasengan to take down the Joker. Maybe the Joker has a new evil plan involving stealing chakra or something, and Naruto just won't stand for it.
One interesting plot could be that the Joker somehow gets hold of the tailed beasts' power. He then uses this power in his own twisted way, creating a new kind of threat in the Naruto world. This would force the ninja to not only fight against his physical strength but also his unpredictable and crazy nature. The story could then focus on how the ninja, led by Naruto, try to outwit the Joker and regain the tailed beasts' power.
