One popular plotline is Aang and Zuko teaming up to face a new threat to the Four Nations. Maybe a long - lost ancient evil that requires both the Avatar's bending skills and Zuko's strategic mind. Another is a story where they go on a journey to understand each other's pasts better. This could involve visiting places that were significant in their respective childhoods.
Fanfic writers often start with their initial distrust. Since they were enemies at first, writers show how they gradually break down those barriers. They might have them share a common goal, like protecting a village from a group of bandits. Through working together towards this goal, they start to respect each other's abilities.
One idea could be a crossover where Ben 10's Omnitrix malfunctions near Avatar Aang's world. Ben and Aang team up to face a new threat that is causing chaos in both their realms. Maybe some of Ben's alien forms have unexpected interactions with the bending abilities in the Avatar world.
One great 'Avatar Zuko Fanfic' is 'The Phoenix and the Dragon'. It delves deep into Zuko's journey of self - discovery after the end of the war. The story shows his struggles with his new role as Fire Lord and how he deals with the remnants of his past traumas. It also has some really interesting interactions with the other characters from the Avatar universe, like Aang and Katara, who help him along the way.
Maybe a plot where Mai is kidnapped by enemies of the Fire Nation who want to use her to get to Zuko. Zuko then embarks on a dangerous rescue mission. Along the way, he realizes just how much Mai means to him. Or a story where Zuko and Mai are forced into an arranged marriage by Fire Nation politics. At first, they resist, but as they spend more time together, they start to develop real feelings for each other that go beyond the political arrangement.
If Aang and Zuko were brothers, it could change the Avatar World by creating a new era of peace. Their combined influence could lead to better relations between the Fire Nation and the other nations. For instance, Zuko's connection to the Fire Nation's royalty and Aang's role as the Avatar would mean they could work together to rewrite treaties and promote equality.
One interesting storyline could be Aang and Zuko teaming up to teach the next generation of benders. They combine their different bending knowledge and ways of life. Zuko could teach firebending discipline while Aang imparts the spiritual side of bending.
Well, in a zuko x aang fanfic, the exploration of their powers together can be really interesting. Aang can control air, water, earth and fire, and Zuko is a firebender. Their combined abilities can create unique storylines, like fighting a new enemy that requires both their skills. Also, their friendship has so much potential for development in fanfics. They start from being on opposite sides and then gradually come to understand and care for each other, which can be explored in many different and fascinating ways.
One great 'zuko x aang fanfic' is 'The Bond Beyond Fire and Air'. It beautifully explores their friendship evolving into something more. The character development in it is really well - done.
