An interesting idea could be that the Genie accidentally grants a wrong wish. Let's say Aladdin wishes for something to help him defeat Jafar, but due to a miscommunication, it backfires. This leads to a situation where Aladdin has to find a way to reverse the effects of the wrong wish and still defeat Jafar. It could add a lot of comical and tense moments to the story. For example, he might be turned into a small animal for a while and has to rely on his wits and the help of his friends in this new form.
Maybe in an alternate ending, Aladdin and Jafar end up teaming up. They realize that there is a greater threat to the kingdom that neither of them can face alone. This new enemy could be an ancient evil that was sealed away long ago but is now breaking free. Aladdin and Jafar have to put aside their differences and combine their skills and knowledge. The Genie is initially skeptical but then joins them. They manage to defeat the ancient evil, and in the process, Jafar has a change of heart. He decides to use his magic for good, and Aladdin, Jasmine, and Jafar work together to rebuild and improve the kingdom.
One possible alternate ending could be that Jafar actually manages to outwit Aladdin in the final battle. Instead of Aladdin winning and getting the girl and the kingdom, Jafar takes over completely. He turns the kingdom into a dark and desolate place, with all the citizens living in fear. Aladdin is banished to the desert, and Jasmine is forced to be Jafar's prisoner. This would be a much darker and unexpected ending compared to the original.
One interesting idea could be that Harry decides not to defeat Voldemort in a traditional battle. Instead, he uses a powerful spell of love and redemption to turn Voldemort back to his original self, Tom Riddle, a lost and confused boy. This would completely change the whole dark - vs - light dynamic of the story.
In some twilight alternate ending fanfiction, Jacob might end up with Bella. This could happen if Edward decides to leave for good, perhaps to protect Bella from the vampire world in a different way. Jacob, being the ever - present protector, steps in and Bella realizes she has deeper feelings for him.
A third idea is that Genie gets a chance to be human for a short time. Aladdin helps him experience all the things he's always wanted to do as a human, like falling in love or having a family. But there are some rules that come with this transformation, and if they're not followed, Genie could be trapped in a bad situation forever.
One idea could be that Aladdin takes Jasmine on a secret journey to a hidden part of the desert where there are magical creatures she has never seen before. Another could be a story where Jasmine has to save Aladdin when he gets trapped in an ancient, enchanted cave. Or perhaps a fanfic where they both work together to improve the lives of the poorest people in Agrabah, facing many challenges along the way.
One idea could be that Aladdin, after becoming a prince, has to deal with various princesses from different lands who are all attracted to him for different reasons. Maybe some are charmed by his heroic deeds, others by his newfound wealth and status. Another plot could be that the genie accidentally creates a situation where multiple female characters from Agrabah develop feelings for Aladdin at the same time, leading to a series of comical and romantic misunderstandings.
One idea could be that the genderbent Aladdin is a street - smart girl trying to steal to survive in the city. She meets a genderbent Jasmine who is a prince disguised as a commoner to explore the city. They team up to outwit the evil sorcerer.
One interesting idea could be the role reversal in relationships. For example, if Aladdin is female, her interactions with Jasmine might change. Maybe she'd be more cautious or have a different approach to wooing the princess. Another aspect could be the new challenges she'd face in the male - dominated society of Agrabah, like having to prove herself in a different way compared to the original male Aladdin.
One idea could be that Aladdin, while on one of his adventures in the marketplace, stumbles upon a magical item that transports him to Hercules' world. There, he meets Hercules and they team up to defeat a common enemy, like a powerful sorcerer who is causing chaos in both their realms.
One plot idea could be that Aladdin and Jasmine go on a magical adventure outside of Agrabah to a far - off land full of strange creatures. They have to work together to overcome the challenges there, like befriending a powerful but initially hostile magical being. Another could be a story set during a festival in Agrabah where they get separated in the chaos and have to find their way back to each other while dealing with various misunderstandings. And perhaps a plot where they have to deal with a new threat to the kingdom that is disguised as a friendly visitor.
