Well, Jack could travel back to the time of his parents. He might get to see how they met and fell in love, and in the process, he could accidentally change something that would have a big impact on his own life. For example, if he stops his parents from meeting, he then has to find a way to fix it so he can exist again.
He could time travel to a period when there was a great treasure that was lost forever in his own time. Jack would then use his knowledge of the future and his pirate skills to try and find this treasure. Along the way, he would have to deal with the different rules and cultures of that time period, which could lead to some really interesting interactions and challenges.
In a Jack Sparrow time travel fanfiction, he could be sent back to the time of the ancient pirates. There, he meets the predecessors of his crew and has to prove himself worthy of being a pirate. He might learn new sailing techniques and bring back some ancient pirate wisdom to his own time, all while getting into all sorts of comical and dangerous situations typical of Jack Sparrow.
A popular plot is where the reader is a magic - user in a world where pirates and magic co - exist. Jack Sparrow is intrigued by the reader's powers and tries to get them to use their magic for his own gain, like finding hidden treasures. But as they spend more time together, he starts to fall for the reader beyond just their magical abilities. Or perhaps the reader is a governor's daughter who is kidnapped by Jack's enemies, and he decides to rescue her for his own reasons, which then leads to a relationship as they go on adventures together.
One idea could be a crossover with 'Pirates of the Caribbean' and 'Peter Pan'. Jack Sparrow could find himself in Neverland and have all sorts of adventures with Peter and the Lost Boys. Maybe he'd try to steal the fairy dust from Tinker Bell or have a sword fight with Captain Hook over some hidden treasure on the island.
Perhaps the story could revolve around her trying to clear her father's name. There could be some false accusations against Jack Sparrow, and his daughter sets out on a journey to prove his innocence. She might encounter old enemies of her father and have to use her wits and skills to outsmart them.
Well, it could be about Naruto having Jack Sparrow's adventurous spirit. Maybe he sails the seas in the Naruto world, using his ninja skills on pirate ships. He might face new enemies that are a mix of Naruto's foes and Jack Sparrow's rivals.
One possible plot could be that Jack and Angelica are on a new adventure together. They are forced to work closely to find a hidden treasure. Along the way, they face many challenges and in a moment of victory and celebration, they share a kiss. It could be a spontaneous moment, filled with the excitement of the discovery and their underlying attraction for each other.
One idea could be that Hermione, with her magical knowledge, ends up on Jack Sparrow's ship. Maybe she uses her magic to help them outwit a powerful sea monster that's been plaguing their voyages. Another plot could involve Hermione and Jack Sparrow teaming up to find a lost magical artifact that has both magical and nautical significance. For example, it could be a key that unlocks a hidden treasure chest that contains a spellbook from an ancient wizard who was also a sailor.
Well, it's not a traditional or common concept. Fanfiction usually involves playing within the boundaries of a single fictional universe or at least related ones. Harry Potter has its own set of rules, characters, and storylines, and the same goes for Jack Sparrow's world. However, in the realm of fan creativity, anything can be possible. Maybe someone could write a story where Harry Potter is a big fan of the tales of Jack Sparrow and tries to incorporate some pirate - like adventures into his magical quests.
The East India Trading Company could still be a major antagonist. They might be even more determined to capture Jack Sparrow, especially if they discover his non - human nature and fear what he could do. They would see him as a threat to their control over the seas and trade.
One interesting plot could be a character going back in time to prevent a certain card from being created, which then changes the whole Yu - Gi - Oh! tournament scene. For example, if the Blue - Eyes White Dragon card was never created, how would the power balance shift among duelists?
