One interesting plot could be that there is a threat to the spirit world that only Aang and Zuko can stop together. Since Aang has a connection to the spirits as the Avatar, and Zuko has his own experiences with the spirit world, they team up. They might have to journey through different spirit realms, facing challenges and making new spirit allies along the way. This would be a great way to explore their characters more deeply and also show their growth as individuals and as friends.
A plot could be that Aang and Zuko discover a new form of bending that combines air and fire. They have to work together to master it and understand its implications for the world. Another idea is that they are sent on a diplomatic mission to a far - off land where they face cultural differences and have to rely on each other to succeed.
One idea could be a time - travel fanfiction. Zuko and Aang could be sent back in time to the era before the war started. They would then have to use their knowledge of the future to prevent the war from ever happening. This would involve them working together to change the minds of key people and stop the events that led to the conflict.
I'm not sure specifically as there could be many different stories within that fanfiction. It might be about Zuko and Aang's relationship, perhaps in an alternate universe or a situation not shown in the original series. It could explore their friendship, their adventures together, or even some creative scenarios that fans have come up with.
One idea could be that Naruto and Daenerys are brought together by a powerful magic or a prophecy. They initially misunderstand each other due to their different backgrounds. Naruto thinks Daenerys is too power - hungry, and she thinks he's a strange warrior. But as they face challenges together, like a new, powerful dark force emerging in both of their worlds, they learn to respect and trust each other. Their combined forces, Naruto's ninjutsu and Daenerys' dragons, prove to be a formidable defense.
One plot idea could be that Towa, who is a villain - ish character, has a change of heart and teams up with Gohan to protect the Dragon Ball universe from a new, powerful threat. Maybe they have to travel to different dimensions to gather special artifacts to defeat this threat, and along the way, they learn to understand and respect each other's powers and motives.
One idea could be that they have to team up to stop a powerful tech - based villain who is stealing data from all the major corporations in the city. They would need to use their combined skills of web - slinging and acrobatics to infiltrate the villain's high - tech lair.
A plot could involve Female Naruto being an outcast in the village because of her different way of doing things. Minato, as the Hokage, takes an interest in her and decides to train her personally. He discovers that she has a unique chakra nature that no one has seen before. They embark on a journey to understand this chakra and in the process, they form a strong bond of friendship and mutual respect. Along the way, they face opposition from some of the more traditional villagers who are skeptical of Female Naruto.
One idea could be that Kaguya is reborn in a different form and Naruto has to help her remember her past without her turning evil again. It could involve them traveling through different dimensions in the Naruto world to piece together her memories.
Well, here's another plot. Madam Malkin could be visited by a strange wizard who tries to put a curse on her shop. Harry, being the hero he is, comes to her rescue. As they try to figure out who the wizard is and why he targeted the shop, they have to rely on each other's skills and knowledge. This not only shows their friendship but also creates an exciting adventure - filled story.
One idea could be that Darkseid tries to corrupt Supergirl in a non - physical, more ideological way. He might tempt her with power and a different view of the universe. For example, he shows her how the current state of the universe has flaws and that his way could 'fix' it. Supergirl, of course, has to resist this temptation using her strong moral compass.
