In some fanfictions, Aang's energybending could be explored in a more character - development - centered way. For instance, after a difficult battle, Aang realizes that his energybending has a connection to his inner peace. He then goes on a journey to better understand this connection and in the process, becomes an even more powerful and wise Avatar. He might learn that by maintaining a perfect balance within himself, his energybending can reach new heights and he can use it to heal not only physical wounds but also emotional and spiritual ones of those around him.
Another place could be FanFiction.net. There are many dedicated Avatar fans who post their stories there. Just use the search function and type in 'aang energybends' to narrow down your search. However, the quality may vary, so you might need to read a few to find the really good ones.
One interesting aang hair fanfiction could be about Aang using his hair in a unique way during a battle. Maybe his long hair gets caught in the wind and he uses it as a distraction for his opponents. For example, he could swirl his hair around to create an illusion of multiple attackers, catching the enemy off - guard.
One interesting Katara and Aang fanfiction could be about their adventures after the end of the original series. Maybe they travel to new lands and discover new bending techniques together. Another could be a story that focuses on their relationship development during a time when the Fire Nation is trying to make a comeback. There are also fanfictions that might explore an alternate universe where Katara and Aang meet in different circumstances, like if Katara was from the Fire Nation and Aang was from the Water Tribe.
One interesting 'Aang puberty fanfiction' could be about Aang struggling to control his newfound strength during puberty while also dealing with his Avatar duties. For example, he might accidentally cause a stronger gust of wind due to hormonal changes affecting his bending.
One interesting Dark Avatar Aang fanfiction could be where he uses his newfound dark powers to challenge the traditional order of the Four Nations. Maybe he decides that the old ways are holding the world back and tries to reshape it in a more radical way.
There could be a fanfiction where Katara discovers she's pregnant during a journey. They then have to cut their adventure short and return to a more stable place. Along the way, Aang uses his airbending to keep Katara comfortable during the pregnancy, like creating gentle breezes to cool her when she's feeling hot. This would show their love and care for each other during this special time.
One interesting story could be that Aang and Katara meet in a different time period, like in a modern world. They have to adapt to new technologies while still maintaining their connection. Aang might be fascinated by things like cars and airplanes, and Katara could be intrigued by modern medicine.
I'm not really into that kind of fanfiction. However, some popular fanfiction platforms like Archive of Our Own might have such stories. You can search there using the tags 'korra' and 'aang' to find relevant works.
Yes, there are quite a few. Some focus on Aang's adventures in the gaming world, like him using his airbending skills in a virtual reality game. For example, in one fanfiction, Aang teams up with other gamers to defeat a powerful in - game boss that's threatening the virtual world.
One interesting 'azula and aang fanfic' story could be where they start as enemies but gradually come to understand each other. Maybe Azula, who is initially bent on defeating Aang, realizes the true meaning of balance that he represents. Another could be a time - travel story where Aang and Azula meet in a different era and have to team up to face a new threat. There could also be a story where Azula is redeemed through her interactions with Aang and they form an unlikely friendship.
