There could be a lemon merchant. This character might be a jolly fellow who travels around selling different kinds of lemons. He could get caught in the middle of the conflict between Jasmine and Jafar. Maybe he has some secret knowledge about the lemons that could help Jasmine defeat Jafar's plans.
Just say 'no' directly. Sometimes the simplest answer is the best. If someone asks you to be involved in Jafar fanfiction, a flat 'no' can be very effective.
One way could be simply stating that you don't like the character of Jafar enough to engage in fanfiction about him. For example, 'I'm not a fan of Jafar, so I won't be part of any Jafar fanfiction.'
Well, one aspect could be the character dynamics in this fanfiction. Sinbad is often depicted as a heroic and adventurous character, while Jafar is known for his villainous nature. In a lemon fanfiction, they might be exploring a more complex relationship that goes against their traditional portrayals. Maybe it shows a side of them where they find common ground or an unexpected attraction.
He could have been a lost wizard from another realm who ended up in Wonderland by accident. Maybe he was banished from his own land and had to find a new place to practice his magic.
One idea could be a story where Sinbad, the adventurous sailor, stumbles upon Jafar's lair during one of his voyages. Jafar, being the cunning sorcerer, initially sees Sinbad as a threat but then realizes he could use Sinbad's skills for his own gain. Sinbad, on the other hand, tries to outwit Jafar and free those who are under Jafar's spell in the lair.
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.
A Jafar and Jasmine fanfic might explore an alternate universe. For example, if Jafar was not evil from the start. He could be a powerful sorcerer who is initially misunderstood. Jasmine, being the curious and strong - willed princess she is, tries to understand him better. Their interactions could range from magical duels to deep conversations about the nature of power and freedom, which gradually leads to a romantic relationship.
