I'm not sure specifically as there could be many different fanfictions with that title. It might be about Aang's journey to discover another airbender in a world where they are thought to be nearly extinct. Maybe he meets this new airbender in a far - flung corner of the world and they team up to face new challenges.
Well, in 'Aang Finds Another Airbender Fanfiction', it could start with Aang sensing an airbending presence that he hasn't felt in a long time. He then embarks on a quest to find this other airbender. Along the way, he might face obstacles like the Fire Nation remnants or natural disasters. Once he finds the other airbender, they could learn from each other and combine their airbending skills to bring something new to the world of bending.
There are several possibilities. It might be an airbender who was born outside of the Air Nomads, perhaps from a mixed - race family. Or it could be an ancient airbender who was trapped in a spirit realm and has now returned. Another option is that it's a new airbender who has spontaneously developed the ability through some kind of unique event or connection to the spirit world.
Some fanfictions in this category could focus on Aang's relationships. For example, a story about how Aang helps Toph deal with a family issue that she's been hiding. This would show a different side of Aang, not just as the Avatar but as a true friend. It could also explore how their friendship deepens through this experience.
One popular plot is a female version of Aang having to deal with the same challenges of mastering the elements but with a different perspective. For example, she might face more doubts from the male - dominated bending world about her abilities. Another plot could be her forming unique relationships with the other characters. Like, her friendship with Katara might be different as they could bond over their shared experiences as female benders in a tough world. Also, her romantic relationships could be explored in new ways, perhaps with Zuko, where their story would be different from the original due to her being female.
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, physically, a female Aang might have different hairstyles and clothing. Instead of Aang's simple monk robes, she could have a more feminine take on them, like with added ribbons or a different cut. Her hair could be longer and styled in ways that are more typical of female characters in the Avatar world. In terms of her bending style, it might be more graceful. While Aang was fluid, a female Aang could bring an extra level of elegance to her airbending moves.
One great Aang fanfic could be one where he has to face an unexpected new threat in the Spirit World. It might explore his growth as the Avatar even further, showing his unique connection to the spirits and how he uses airbending in creative ways to overcome challenges.
You can start by looking on popular fanfiction websites like Archive of Our Own or FanFiction.net. Just search for 'Aang not the last airbender' in their search bars and you'll get a list of relevant stories.
Another aspect is the relationships in the fanfic. Aang has important relationships with Katara, Sokka, Toph, and others. If a fanfic can develop these relationships in new and interesting ways, it's great. For instance, a story where Aang and Katara have a misunderstanding that they need to work through, which could test their relationship and show their individual growth as characters.
One great Aang fanfic is 'Aang's New Adventure'. It takes place right after the end of the series. In this fanfic, Aang has to deal with some leftover Fire Nation rebels who don't want to accept the new peace. It's really exciting as it shows Aang using his bending skills in new and creative ways to bring about peace once again.
Common themes often include friendship and how it can transform into something more. Also, the idea of breaking traditional boundaries. In these fanfics, Aang may be facing challenges that come with being in a relationship that goes against the norm in his world. And there's often a focus on the emotional journey, like how he deals with his new - found feelings and the reactions of others.
