A really engaging plot might involve a love triangle where one character in the triangle discovers a hidden power or ability. This new development throws the whole dynamic of the love triangle into chaos as the other two characters have to re - evaluate their feelings for the changed person. And the character with the new power also has to figure out how this affects their relationships in the love triangle.
One interesting plot could be where the two rivals in the love triangle have to team up to save the object of their affection from a great danger. This forces them to put aside their differences and they end up respecting each other more in the process.
In some avatar love triangle fanfiction, the object of the love triangle may be a powerful avatar who has to choose between two very different partners. One could be from her own tribe, representing familiarity and tradition, while the other could be from an outside group, representing new ideas and a different way of life. The avatar has to struggle with her feelings and her duties to her people as she makes her choice.
One interesting plot could be where two ninjas fall for the same female character. For example, Kai and Jay both having feelings for Nya. There could be a lot of friendly rivalry and misunderstandings between them as they try to win her heart. It might involve challenges like who can better protect her or who can complete a task to impress her first.
One interesting plot could be where a character who is in a love triangle has to choose between love and power. For example, a nobleman might be torn between a common - born girl he truly loves and a high - born lady who can bring him political advantages.
One common plot is when Hermione is caught between Harry and Ron. For example, in some fanfictions, after a big battle, Harry realizes his deeper feelings for Hermione but Ron has also been in love with her all along. This creates a tense situation where Hermione has to figure out her own feelings while also trying not to damage their friendship.
In certain fanfictions, Lavender might be a much more complex character than in the original books. She could be secretly aware that Ron's heart belongs to Hermione but still can't help her own feelings. Meanwhile, Hermione is conflicted between her pride and her love for Ron. This love triangle then becomes a story of self - discovery and acceptance for all three characters.
One possible plot could be that the humans develop a new technology that neutralizes the Na'vi's natural advantages. For example, they create a device that disrupts the connection the Na'vi have with Pandora's ecosystem. Another plot might involve a human spy within the Na'vi ranks who provides crucial information to the human forces, leading to their victory. Maybe there could also be a situation where the humans manage to form an unexpected alliance with a part of Pandora's wildlife that helps them turn the tables on the Na'vi.
One interesting plot could be that the Na'vi discover the wizarding world. They might be intrigued by magic and the Hogwarts castle. Maybe some Na'vi students could be sent to Hogwarts to learn magic, and they'd bring their own unique skills like their connection with nature and flying on their banshees. This would create a whole new dynamic in the Hogwarts classrooms and grounds.
A possible plot is that a group of rebels from Star Wars flee to Pandora. There, they meet the Na'vi and learn from their ways of living in harmony with nature. In return, they teach the Na'vi about advanced technology like starships. Or perhaps an Avatar, who has the ability to transfer their consciousness, could be a key figure in uniting the two universes. The Avatar could communicate with both the Na'vi and the Star Wars characters, bridging the gap between their different cultures and powers.
One interesting plot could be Jake and Neytiri facing a new, unforeseen threat to Pandora while also dealing with their relationship growing stronger. Maybe they have to team up with some unexpected allies.
There are fanfictions where a love triangle forms because of a magical spell. For example, a spell makes Percy forget his love for Annabeth and start having feelings for another demigod. Annabeth then has to fight to break the spell and win Percy back. This often involves her going on dangerous quests and facing her own insecurities about their relationship.
There are also fanfictions centered around Sasuke - Naruto - Ino. Sasuke is often the aloof character, while Naruto has his own charm. Ino might be attracted to Sasuke's mystery, but also see Naruto's good heart. This can lead to a love triangle where Naruto is caught between his friendship with Sasuke and Ino's possible interest in both of them.
