First, re - read both series to get a firm grasp on the characters, their personalities, and the worlds they inhabit. Then, decide on a central plot point that would bring the two worlds together. It could be as simple as a portal opening between the two realms. Next, choose which characters from each series will be your main focus. For example, you might want to start with Feyre and Celaena as they are strong female leads.
Well, start small. Maybe write a short scene where two minor characters from each series meet first. This can help you get a feel for how the two worlds blend. You can then build on that. Consider the language and the cultures of both worlds. How would the characters from 'acotar' communicate with those from 'tog'? Will there be misunderstandings? By answering these questions in your writing, you can create a more engaging and believable crossover fanfiction.
When writing an ACOTAR and TOG crossover fanfic, character development is key. You can't just throw the characters together without considering how they will grow and change in this new situation. For instance, if you pair up Chaol from TOG with Lucien from ACOTAR, think about how their different backgrounds and experiences will influence their relationship. Maybe Chaol's loyalty to his kingdom will be challenged by Lucien's more fluid view of loyalty among the fae. Also, don't be afraid to experiment with the magic systems. Try to find unique ways for the characters to use their combined powers. This will make your fanfic more engaging and original.
One idea could be to have the characters from 'Throne of Glass' (TOG) and 'A Court of Thorns and Roses' (ACOTAR) meet in a magical realm created by a powerful ancient artifact. For example, Aelin from TOG could be on a quest to find a way to defeat a new, powerful enemy and accidentally stumbles into the world of ACOTAR. There, she meets Feyre and they initially have a bit of a clash due to their different upbringings and leadership styles, but then realize they can work together to solve a problem that threatens both of their worlds.
Good fanfic writing for a TOG and ACOTAR crossover requires a deep understanding of the source materials. Research the lore, the politics, and the relationships in both series. For the plot, think of something that challenges the characters from both worlds. A good way is to introduce a new, powerful enemy that neither world has faced before. In terms of character development, let the characters grow and change as a result of their interactions. For example, if Rowan from TOG meets Azriel from ACOTAR, they could learn from each other's combat skills and ways of thinking. Also, pay attention to the pacing of your story. Don't rush the important moments and build up the tension gradually.
Perhaps a crossover where the magic systems cross over. The valg from 'tog' could somehow seep into the world of 'acotar' and the characters from 'acotar' have to learn about the valg and how to combat it using the knowledge that Aelin and her crew have from 'tog'. This could lead to some really interesting battles and alliances.
First, read the original acotar books thoroughly. This will give you a good understanding of the world, the characters, and the rules. Then, think of a unique concept. It could be a new adventure for the characters or a different take on an existing event.
You should also focus on character development. If you're crossing with the Fullmetal Alchemist world, consider how Chrollo would interact with the Elric brothers. He might see their search for the Philosopher's Stone as something he can use for his own purposes. Start with a small scene that sets the tone, like Chrollo arriving in Amestris and observing the alchemic practices there, and then build the story from that initial encounter.
First, decide which universe you want to crossover with Tracer. Then, research that universe thoroughly. For example, if it's a Star Wars crossover, know the rules of the Force, the different species, and the technology. After that, create a plot that involves Tracer being thrust into this new universe. Maybe she's chasing a villain through a wormhole that leads to the Star Wars galaxy. Start with an engaging opening scene, like Tracer suddenly appearing in the middle of a lightsaber duel.
First, decide which universes or characters you want to crossover with Gogeta. Then, think about the plot. It could start with a disruption in the Dragon Ball universe that leads Gogeta to another world. For example, if it's a crossover with the One Piece universe, it could be a mysterious energy that pulls Gogeta to the Grand Line.
First, decide which universe you want to cross Ichigo over with. Then, research the rules and characteristics of that universe. For example, if it's a crossover with the Star Wars universe, learn about the Force and the different species. Next, think about how Ichigo would fit into that world. What would his role be? After that, start with an interesting hook in your story, like Ichigo suddenly appearing in a strange new place.
First, decide which universe Gowther will cross over into. Then, think about how Gowther's character traits and powers will interact with the new world. For example, if it's a crossover with 'Naruto', Gowther's power to manipulate memories might be a big deal in a world where knowledge and hidden pasts are important. Just start with a simple scene, like Gowther arriving in the new world.
