Maybe it's because the plot or character development in those fanfics doesn't meet expectations. Sometimes the writing style or storylines can be off-putting.
Supernatural fanfiction might be seen as toxic because of a few reasons. Sometimes the characterizations are way off, or the storylines are just too far-fetched and don't fit the original universe. Also, there could be a lot of drama and conflict within the fanfic community itself that spills over and gives it a bad reputation.
Multiplayer travel was often considered a toxic point in novels because it often brought about many problems and contradictions.
Because different time lines may produce different values and codes of conduct, many people crossing over may lead to different conflicts and contradictions. For example, one person's timeline may be different from another person's timeline, which may lead to misunderstandings and disputes between different people.
Many people could also cause changes in history. One person's timeline may be different from another person's timeline, which may lead to changes and discrepancies in history. This discrepancy could lead to different explanations and evaluations of past events, resulting in historical upheaval and contradictions.
In the end, the transmigration of many people might destroy the stability of the time cycle and history. Different people traveling through time might have different results, which might lead to the destruction of the time cycle and the instability of history.
Therefore, multiplayer transmigration was often seen as a bad element in novel writing because it could ruin the plot and story, causing the reader to be confused and dissatisfied.
One common theme is the symbolism of the jackets. They often represent the connection between Catra and Adora, like a physical manifestation of their bond. For example, in many fanfics, when one gives the jacket to the other, it's a sign of trust or a new level of closeness.
Obviously, Catra and Adora are the central characters. Their relationship forms the basis of the family in the fanfic. And likely their children, if they have any in the story, would also be important characters.
One sign is constant criticism. In a toxic friend story, you might notice the friend always finding fault with you, like your appearance or choices. Another is jealousy. If the friend is always envious of your success or new relationships, that's a red flag. Also, if they try to control you, for example, telling you who you can or can't be friends with, it's a sign of toxicity.
One popular 'Catradora' fanfic is 'The Adventure Beyond the Whispering Woods'. It focuses on Catra and Adora's journey exploring an unknown part of their world. Another great one is 'A New Beginning for Catradora' which is about them starting a new chapter in their relationship in a post - war setting. And 'Friendship and More' that shows the growth of their relationship from friendship to something deeper in a really heartwarming way.
One popular theme is the family's adventures together. They might go on quests or explore new lands. Another theme could be how they handle challenges as a family, like dealing with outside threats or internal conflicts within the family unit.
There's also 'Jackets and Journeys'. This fanfic not only features the significance of the jackets but also takes the characters on an adventure. It shows how Catra and Adora's bond grows stronger while wearing those jackets during their travels, and it has some beautifully written emotional scenes.
