Reactions to changes in the Supernatural world itself are quite common. Maybe a new law or rule has been established in the world of demons and angels, and we see how the characters respond. Additionally, the theme of reactions to loss is prevalent. When a character is lost, either temporarily or permanently, the others' reactions are explored, which can be very emotional and add depth to the story.
Since I'm not very familiar with this specific type of fanfiction, it's hard to say for sure. But perhaps themes like friendship, cooperation, or the development of a unique bond could be common, as reaction time might imply some sort of interaction and 'kyutie' could be a character with certain qualities that lead to interesting relationship dynamics.
A frequent theme is the exploration of character relationships in the future. For instance, how do Naruto and Sasuke's relationship evolve further? And how do other characters react to this? Also, the theme of facing new, more powerful threats together often appears. Characters' reactions to these threats can vary from determination to fear.
One common theme is the reaction to power. For example, when a character reveals a new level of power, how others in the story respond. This can range from shock to envy.
One common theme is separation. Fans often write about how hard it is for the characters to say goodbye to their dragons, like Hiccup and Toothless. It's a very emotional moment that many fanfiction writers explore.
Mystery is also a common theme. There are fanfictions where the origin or true nature of certain elemental reactions is a mystery. The characters then embark on a journey to uncover the secrets. Additionally, some fanfictions focus on the cultural aspects of Genshin Impact, and how different regions have different attitudes towards elemental reactions.
One common theme is character development. Since it's reaction - based, it often shows how characters grow and change in response to different events. For example, Kirito might react to a new threat in the game, and through that, we see his character evolve.
One common theme is the exploration of the consequences of alchemy. In Fullmetal Alchemist, alchemy has a price, and fanfictions often delve deeper into how characters deal with those consequences, both physically and emotionally. Another theme is the relationship between the brothers, Edward and Alphonse. Fanfictions might explore different scenarios of their bond, like how they support each other in new and challenging situations.
In 'supernatural fanfiction', a frequent theme is the alternate universes. Writers like to imagine different versions of the 'Supernatural' world, where things happened differently. Romance is also a big theme, whether it's between the main characters or new characters introduced in the fanfic. Also, the origin stories of the supernatural beings are often explored, giving more background and depth to the existing lore.
One common theme is friendship. Characters' reactions often highlight the bonds they form with each other. For example, when a character is in danger, how their friends react shows the strength of their friendship. Another theme is loyalty. The way characters respond to situations can show their loyalty to their house or their cause.
Many Supernatural Wings Fanfiction explore the idea of flight. It could be a character getting a chance to fly with an angel's wings or the wings being used in a battle in the air. Also, the theme of secrecy and revelation is common. A character might discover another character's wings, which could lead to a whole new plotline of trust and secrets in the relationship. Some fanfics also play with the idea of damaged or broken wings and the journey of healing them, which can be a metaphor for a character's emotional or physical recovery.
