What could be the story in the 'Aang and Katara have a baby fanfiction'?

The main characters are obviously Aang and Katara. Aang, the last airbender, and Katara, the powerful waterbender. And of course, their baby would be a central part of the story as well.

Well, some fanfictions might focus on the baby's relationship with the other characters. Maybe the baby has a special bond with Sokka, Katara's brother, and he becomes like a fun uncle figure. Or perhaps the baby's birth brings new hope to the different tribes, and there are celebrations across the land. Some stories could also explore how the baby's existence changes the dynamic between Aang and Katara. They might have some disagreements on how to raise the baby, like whether to be more strict or more lenient.

It could also be that Katara was being overly critical of Aang's progress in learning new skills. Aang might feel frustrated and angry if Katara is constantly pointing out his flaws instead of being more encouraging, especially if he's already trying his best.

It could be that the fanfiction writers wanted to explore a more complex and darker side of relationships. They might have written scenarios where Aang hates Katara due to jealousy, perhaps over her friendship with another character. This would add an interesting twist to the original relationship dynamics between them.

A plot twist might be that there are forces trying to harm the baby because they fear its potential power. This could lead to Katara and Aang going on a dangerous journey to protect their unborn child. They might encounter new allies and enemies along the way, and it would test their relationship as they face these challenges together.

It could be a grand affair with elements from both their cultures. Aang being an Air Nomad, there might be floating lanterns and gentle wind chimes. Katara, from the Water Tribe, could have a beautiful ice sculpture as part of the decor. Their friends from all over the world would come to celebrate. Zuko would be there, of course, representing the Fire Nation. The ceremony would likely take place near a body of water, with Aang wearing his traditional Air Nomad robes and Katara in a stunning Water Tribe wedding dress, perhaps with blue silk and white fur accents.

Well, perhaps Aang realizes that Katara has feelings for someone else and decides to let her go for her own happiness. This could lead to a new phase in their friendship where there's less tension and more mutual understanding.

One possible reason could be their different approaches to life post - war. Aang is the Avatar and has a whole world to look after, while Katara has her own tribe and personal goals. Their busy schedules might pull them apart. For example, Aang might be constantly traveling to different nations for diplomatic and Avatar - related duties, leaving Katara feeling lonely. Also, they might have different ideas on how to handle future threats. Aang may prefer a more pacifist approach which Katara might not always agree with, especially if it endangers the people she loves.

Some fans might depict the baby with light blue eyes like Katara and light brown hair like Aang. Others could give the baby a unique skin tone that is a blend of the Air Nomad and Water Tribe complexions. The baby might also be drawn with a small ponytail like Aang's, or with Katara's hair accessories.

Perhaps Aang has a vision of the future where Katara is happier without him. So, in the fanfiction, he decides to respect that future and let her go.
