A really interesting plot could involve the concept of alternate realities within the 'Crossed Destinies Fanfic'. Say, there are multiple versions of the same character with different personalities and abilities. When these versions meet, they start to merge or fight for dominance over their shared destiny. This would not only create internal conflict for the character but also impact the overall story arc and the destinies of other characters in the fanfic.
Perhaps a time - travel element in 'Crossed Destinies Fanfic' where a character travels to a different time period within the fanfic universe and alters the destinies of other characters. This could lead to a butterfly effect, completely changing the course of the story. Also, a character getting a premonition about a different character's destiny and trying to change it could make for an exciting plot.
One idea could be characters from different storylines suddenly swapping places in their respective universes. For example, a hero from one story finds themselves in the villain's role in another. Another could be two characters who were never meant to meet in their original stories, meeting in the fanfic and changing each other's fates.
Give them unique backstories. For example, if a character is from a world of magic and is suddenly thrust into a sci - fi world in the fanfic, their magic - based upbringing can shape how they react to the new technology.
One idea could be that Teri and Roman are from rival families in a magical realm. They meet by chance during a magical festival and immediately feel a connection, but their families' feud stands in the way of their relationship. They then secretly meet and try to find a way to end the feud.
One plot idea could be Huedhaut guiding a young protagonist through the challenges of the star - crossed world. Maybe the protagonist is a new soul in this realm and Huedhaut has to teach them about the different constellations and their powers.
One idea could be that Drake and Taylor meet at a music award show. They initially have a bit of a rivalry but gradually realize they have a lot in common artistically. They start collaborating secretly on a song that combines their unique styles.
One idea could be that Jak meets an alternate version of himself from a different dimension. This could lead to a lot of self - discovery as they compare their lives and experiences.
One plot idea could be that Grayson and Teri are from rival families, like in a modern - day Romeo and Juliet scenario. They meet secretly and fall in love, but their families' feud constantly threatens to tear them apart. Another could be that they are in different social classes in a fictional society. Teri is from a lower class but has extraordinary talents, and Grayson, from the upper class, discovers her and they start a relationship that challenges the social norms of their world.
In some fanfictions, there could be a twist where the gods are not as all - powerful as they seem. Maybe they are being manipulated by a greater, unknown force. This would force Percy and his friends to re - evaluate their relationships with the gods and find new ways to deal with the threats to their world. It would also change Percy's destiny as he might have to take on a more independent role in saving the world without relying as much on the gods' help.
Another plot could revolve around the characters having premonitions of the events that are going to occur in the quarry. They then have to decide whether to trust these visions and how to act upon them. This could add a whole new layer of suspense and mystery to the story.
One idea could be a time - travel plot. The Backyardigans accidentally find a magical object in the backyard that sends them to different eras in history. They could have to work together to find their way back home while also learning about the different time periods. For example, they might end up in the prehistoric era and have to deal with dinosaurs.
One idea could be a story where one of the dalmatian puppies gets lost during a family outing and has to find its way back home, facing various challenges along the way.
