One popular theme is alternate universes. Writers like to explore what would happen if the Avatar world had different rules or if characters were in different situations. For instance, an AU where the Fire Nation won the war in the original series.
You can start by looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms have a large collection of fan - made stories related to various shows, including Avatar. Just use the search function and type in 'Avatar' to find relevant fanfics.
Well, their reactions would vary. Aang would probably have a positive reaction overall, as he has a kind heart. He might enjoy seeing different takes on his adventures. Katara could be a bit more critical. If the fanfic misrepresents her character, she'd be upset. Toph would likely laugh at the whole thing. She has a sense of humor and would find it funny how people imagine their world in fanfics.
One idea could be exploring the relationship between the new characters introduced in Avatar 2 in more depth. For example, a fanfic could focus on the friendship or rivalry between two young Na'vi from different clans. Another plot could revolve around a human character who becomes stranded on Pandora and has to learn to survive with the help of the Na'vi. They could discover new areas of Pandora that were not shown in the movie, filled with unique flora and fauna. A third idea might be a fanfic that delves into the backstory of one of the main Avatar 2 characters, perhaps their family history or how they came to be in their current position.
Some might focus on the training of an Avatar's feet. Since the Avatar has to master different bending forms, their feet play a crucial role. In a fanfic, it could be about an Avatar's struggle to perfect the stances that require precise footwork in firebending, like the quick and powerful movements. Or in airbending, where the feet need to be light and flowing. This could also tie in with a mentor - apprentice relationship, where the mentor corrects the Avatar's foot positions to help them improve their bending skills.
To write a compelling character in an Avatar 2 fanfic, start with a clear backstory. For example, if it's a Na'vi character, think about their family, their clan's traditions, and how they grew up. Then, give them a unique personality trait. Maybe they are overly curious like Jake was in the first movie. Also, give them goals. It could be something as simple as wanting to be the best hunter in their clan or as complex as trying to bridge the gap between the Na'vi and humans. Physical descriptions are important too. Describe their blue skin, their long braided hair, and their big, expressive eyes.
One interesting storyline could be about a human who is stranded on Pandora and has to learn the ways of the Na'vi to survive. They form a bond with a particular Pandora creature that helps them in their journey.
It could strengthen their relationships. If they see positive portrayals of their friendships in the fanfic, it might make them appreciate each other more. For example, if the fanfic shows Aang and Sokka's bromance in a great light, they might feel closer. But if there are negative or inaccurate portrayals, it could cause some tension.
It can divide the fandom. Some fans who are interested in the original family - friendly and positive aspects of Avatar may be put off by the existence of adult fanfic. They might feel that it's a stain on the fandom.
Avatar Yangchen fanfics can be really interesting. They often explore the character in more depth than the original source might have. Some fanfics might focus on Yangchen's early days as an Avatar, her training, and the challenges she faced. It gives readers a chance to see a different side of her, one that may not have been fully explored in the main Avatar storyline.
