A theme that often shows up is redemption. Some fanfictions explore the idea that the reader can be the catalyst for Jafar's change and redemption. There's also the theme of mystery. Jafar is a mysterious character, and fanfictions often play on this by having the reader try to figure him out, which adds to the tension and the allure of the relationship.
One common theme is power dynamics. Jafar is a powerful sorcerer and the reader is often in a position where they are either at his mercy or trying to gain some power over him. Another theme is the allure of the forbidden. Jafar is a villain, so being involved with him is something that is not considered proper in the context of the original story.
The theme of transformation is also prevalent. The reader may find themselves changing as a result of their interactions with Jafar, or they may be the force that causes Jafar to transform. This could be a transformation in terms of his personality, his goals, or his view of the world. It makes for a very interesting exploration of character development in the fanfiction world.
The theme of temptation also appears. Jafar might try to tempt Aladdin to the dark side, or Aladdin might be tempted to use Jafar's power for his own good. This creates a lot of interesting conflict and character development in the fanfictions.
One common theme is redemption. Many fanfictions explore whether Jafar can be redeemed after all his evil deeds, and how Aladdin might play a part in that. Another is power dynamics. Given Jafar's thirst for power and Aladdin's more humble origins, their relationship in terms of power is often explored.
Power struggle is a common theme. Since Jafar is always after power in the original story, OCs often get involved in this struggle, either trying to stop him or being tempted by power themselves.
One common theme is adventure. Since Aladdin is known for his adventures in the original story, it's often carried over into the fanfiction. The reader gets to go on exciting escapades with him in the streets of Agrabah or in the magical caves.
I also like 'Jafar's Redemption in Your Eyes'. It's different from the others as it focuses on a more nuanced Jafar who is trying to change because of the reader. It shows how love can potentially transform even the darkest of characters.
One common theme is adventure. Since Magi has a lot of adventure elements in the original story, fanfictions often continue this with the reader character joining Aladdin on his quests. Another is romance, of course, exploring the relationship between Aladdin and the reader.
Well, 'aladdin x jafar yaoi fanfiction' is unique because it goes against the traditional narrative. In the original Aladdin, Jafar is the villain and Aladdin is the hero. But in this fanfiction, it explores a different kind of connection between them. It gives a chance to see the characters in a new light, with different emotions and interactions that are not part of the mainstream story. It also often involves exploring the psychological aspects of how these two very different characters could come together in such an unexpected way.
One common theme is the exploration of power dynamics. Given Jafar's position of power and Jasmine's royalty, there's often a play on who has more control in the relationship. Another theme is redemption. Sometimes Jafar is written in a way that he is redeemed through his relationship with Jasmine.
Power is a common theme. Jafar is a powerful character, and often the relationship with the oc is influenced by his power. For example, the oc might be in awe of his power or try to resist it.
