Well, in such fanfiction, a cool concept might be the characters' interactions. Imagine Harry Potter meeting Aayla Secura. Harry could be intrigued by her Jedi abilities and she might be fascinated by his wizardry. They could learn from each other's skills, like Harry teaching her about potions and Aayla showing him some Jedi combat moves.
Some fanfictions might explore the idea of the two different forms of governance. The Ministry of Magic in Harry Potter's world and the Galactic Republic in Star Wars. There could be a story where they have to work together to solve a problem that involves both magical and political aspects. Maybe a dark wizard has allied with a Sith Lord and they need to combine their resources and knowledge to defeat this new threat.
One common theme could be the clash of different cultures. Harry Potter's wizarding world has its own set of rules and Aayla Secura comes from a very different Star Wars universe. Another might be the exploration of new powers when their abilities combine. For example, how Harry's magic might interact with Aayla's Jedi skills.
One idea could be a crossover where Aayla Secura, using her Jedi skills, somehow gets transported to the Harry Potter universe. She could use her Force abilities to interact with the magical elements there. For example, she might sense the dark magic in the Horcruxes and help Harry and his friends in their quest to destroy them. Maybe she teams up with Hermione, who is fascinated by Aayla's different kind of magic and they learn from each other.
The most interesting aspect is the clash and blend of two very different universes. The Jedi - like abilities of Aayla Secura in the magical world of Harry Potter can lead to some really cool action scenes. For example, her lightsaber skills combined with Hogwarts spells can make for a great battle sequence.
Yes, there are some out there. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Harry Potter x Aayla Secura' and you'll likely find a variety of stories with different themes and plotlines.
One common theme is the exploration of different cultures. Since Harry is from the wizarding world and Aayla is from the Star Wars universe, fanfics often focus on how they introduce their respective cultures to each other. For example, magic spells versus Jedi mind tricks.
Hermione Granger could also be a popular character in this type of fanfiction. She is known for her intelligence and knowledge of magic. In a story with Aayla Secura, she could be the one who tries to understand the new elements from the Star Wars universe and find ways to incorporate them into their fight against any combined threats.
A really interesting fanfic could be set in an alternate universe where Aayla Secura is a student at Hogwarts. She would bring her unique perspective and abilities. Her combat skills and connection to the Force could make her a standout in Defense Against the Dark Arts classes. And she might introduce new forms of martial arts - like those used in the Star Wars universe - to the Hogwarts students.
There could be some out there, but it's not a very mainstream combination. The 'lemon' aspect also makes it a bit trickier as many fanfiction platforms have rules against explicit content. You might try looking on some smaller, more niche fanfiction communities that are less strict about content, but be aware that such content may not be in line with the spirit of the original works.
In a possible fanfiction scenario, Harry Potter might use his magic skills. He could use a powerful spell like 'Protego Maxima' to shield Aayla Secura from an oncoming danger. Maybe she's being attacked by dark forces, and Harry, with his experience in fighting the dark arts, steps in to save her.
Since this is a very unusual crossover, if such fanfiction exists, the main themes could be about exploring the clash of two different fictional worlds. Maybe there would be themes of magic from Harry Potter and the unique aspects of Aayla Secura's world in Star Wars.
