One great Katara fanfic is 'The Waterbender's Journey'. It really delves into Katara's growth as a waterbender and her role in the post - war world. The characterizations are on point, making it a must - read for any Katara fan.
Well, the age of Katara in the comics isn't fixed. It can change based on the plot and the timeline of the story. Sometimes she might be around 18, and in other instances, she could be a bit older, like 20 or 21.
In some cases, the anger could be a catalyst for a more romantic development. Aang expressing his strong emotions might make Katara realize the depth of his feelings for her. Or it could be the other way around, Katara's reaction to his anger could make Aang see her in a new light, leading to a shift in their relationship dynamic towards a more romantic one.
One great Katara and Zuko fanfic is 'The Balance Within'. It beautifully explores their relationship development post - war. It shows how they learn to understand each other's perspectives and grow closer as friends and maybe more. Another is 'A New Alliance' which has an interesting plot where they team up for a mission that forces them to rely on each other and in the process, their feelings start to shift.
The Katara ghost story might be something unique to the local folklore in the Katara region. Maybe it involves a tragic event in the past that led to the appearance of a ghost. For example, if there was a battle there long ago, and a soldier's spirit is said to still linger. However, without more context, this is just speculation.
It's not appropriate. The original Avatar: The Last Airbender series is aimed at a wide audience, including younger viewers. 'Lemon' fanfiction often contains adult - themed content. Katara and Ozai have a relationship in the show that is based on enmity and conflict. Turning this into a sexualized relationship in fanfiction is a misrepresentation of the characters and the story, and is not suitable for the general Avatar fan community.
One great 'Zuko and Katara Fanfiction' is 'The Phoenix and the Wave'. It beautifully explores their relationship development. The story is set in a post - war scenario where they have to work together on a diplomatic mission. Their initial distrust slowly turns into mutual respect and something more.
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.
