Some of it was well - written. There were talented authors who could combine the elements of both universes in a seamless way. They paid attention to the details of both Twilight and Harry Potter and created engaging stories.
It's an odd concept. Harry Potter and General Grievous are from very different fictional universes. General Grievous is from Star Wars with its own set of rules, technology, and themes. Harry Potter is set in a world of magic, wizards, and Hogwarts. Combining them in a fanfiction might seem strange at first, but it could potentially be an interesting exploration of how different fictional elements can interact. However, it might also be seen as a rather far - fetched idea as the two worlds have little in common in terms of basic settings and characters' natures.
No. 'Harry Potter' has a well - defined narrative structure that starts from Harry's discovery of his wizarding heritage and progresses through his years at Hogwarts and his battles against Voldemort. It has a distinct style of magic, different houses in Hogwarts with their own characteristics, and a whole host of magical creatures. Fanfiction usually builds on an established work in a more derivative way, and 'Harry Potter' is far from being a general fanfiction as it is a creative masterpiece in its own right.
I'm not aware of any such fanfiction that would be suitable for general audiences. The idea of such a relationship goes against the established norms and family dynamics in the 'Harry Potter' series. Fanfiction should generally adhere to certain ethical and moral boundaries, and this concept seems rather inappropriate.
One popular trope is the 'alternate universe' where the story takes place in a different setting or with different rules from the original series. For example, a wizarding world where Voldemort never existed. Another is the 'character redemption' trope, like Draco Malfoy getting a chance to be a good person from the start. And 'romantic pairings' that fans love to explore, such as Hermione with someone other than Ron.
It might have Harry Potter somehow transported to the Star Wars universe where he encounters General Grievous. Maybe Harry would try to use his magic against Grievous' combat skills and robotic enhancements. For instance, he could cast spells like 'Stupefy' to try and stun Grievous, while Grievous would use his lightsaber skills and agility to counter. The story could also involve Harry trying to find a way back to his own world, all while dealing with the various threats and politics of the Star Wars universe.
One interesting aspect is the gender - swap. It allows for a fresh take on Draco's character. A female Draco might have different relationships, for example, with Harry Potter. Instead of the typical male - male rivalry, there could be a more complex dynamic, like a begrudging friendship or a different kind of competition.
No. The world of Harry Potter is a magical world for all ages. BDSM involves elements that are not suitable for a general audience, and adding gay themes on top of that in a fanfiction context would be quite far from the intended charm and message of the Harry Potter series. So, it's not likely to find any that are appropriate for a general audience.
The concept of 'Harry Potter loves cock' contains inappropriate and vulgar implications. J.K. Rowling's original Harry Potter series is a work of fantasy aimed at a wide range of audiences, especially children and young adults. Fanfiction should also uphold certain moral and ethical standards, and such inappropriate content should not be promoted or even exist in a proper fanfiction community.
