Writers can create new plot twists in Merlin fanfiction by making Merlin fall in love with someone unexpected, like an enemy from another kingdom. This would create a conflict between his loyalty to Arthur and his new - found love. They could also introduce a new character who is a more powerful wizard than Merlin and who challenges him for the title of the greatest wizard. This would force Merlin to learn new magic and grow in ways he hadn't before.
One way to create plot twists is to play with time. Have Merlin travel back in time and accidentally change something that has a huge impact on the present. Or, writers could give Merlin a prophecy that he misinterprets at first. As he tries to avoid the fate he thinks is coming, he actually sets it in motion. This would add a lot of suspense to the fanfiction. Also, changing Merlin's powers, like making him lose his ability to use magic for a period but gain a new non - magical skill that is equally useful in different situations.
Writers can create new plot twists by changing the established relationships. For example, make Merlin and Morgana secret allies instead of enemies. It would shock the readers who are familiar with the original legend. Another way is to introduce a new powerful magic item that Merlin has to find or protect. This could lead to all sorts of new adventures and challenges for him.
Another way is by withholding crucial information until the right moment. In a mystery story, the writer might not reveal the true identity of a key figure until the end. This builds suspense and makes the twist more impactful when it's finally revealed. Also, subverting expectations can create great twists. If the readers expect a character to act in a certain way based on the story's setup, but then the character does the opposite, it can be a very effective twist.
One way is to mislead the readers. For example, introduce a character who seems to be a hero at first but later turns out to be the villain. Another method is to withhold crucial information until the right moment. Writers can also play with the readers' expectations, like setting up a common plot pattern and then breaking it suddenly.
One unique interpretation could be Merlin having a different origin. Instead of being a simple wizard, he could be part fae. This would add an interesting layer to his character as he'd have to deal with the dual nature of his magic. Another could be a modern - day Merlin fanfiction where he uses his magic in a world full of technology. It would be a cool twist to see how he'd adapt and use his powers without being discovered.
You need to surprise the readers. Think of something unexpected but still makes sense within the story context.
A great way to do it is to introduce an unexpected element near the end. Maybe a character who was thought to be good turns out to be bad, or a solution to a problem comes from an unlikely source.
Writers can start by giving their characters a clear motivation. In 'A New Beginning New Hope' fanfiction, it could be something related to the new start they're having. For example, a character might be motivated by the hope of finding a lost family member. Also, flaws are important. No one is perfect, and having flaws makes the character more relatable. Maybe a character is too impulsive and that gets them into trouble sometimes.
Well, think about the conflict. It could be an external threat like a new villain in Slugterra who is after something that the OC and Twist both care about. Or it could be an internal conflict, like Twist having to deal with his own doubts while the OC tries to help him. Another idea is to incorporate some of the unique slug powers into the plot to make it more exciting.
Some fanfiction writers base new Naruto skills on existing jutsus but then amplify or modify them. For instance, taking the Rasengan and adding a new element to it, like lightning. This gives a familiar skill a fresh and exciting twist.
One way is to create a power struggle. Maybe Merlin's powerful magic makes some in the wizarding world jealous and they try to undermine him. Or there could be a prophecy that involves both Merlin and a key Harry Potter character, like Harry himself. They have to work together to fulfill the prophecy while facing many obstacles.
A plot twist could be that Merlin is not who he seems. Maybe he has an ulterior motive for meeting Shirou, like using him as a pawn in a larger magical game. This would completely change the dynamic between them.
