One idea could be a story where Harry Potter, during one of his travels in the wizarding world, somehow stumbles into the world of El Tigre. Their different powers and personalities could lead to an interesting dynamic. For example, Harry could teach El Tigre some basic magic, and El Tigre could show Harry some of his superhero - like moves.
Perhaps a dark wizard from the Harry Potter world has a plan to take over the world of El Tigre as well. Harry and El Tigre team up to stop this threat. Along the way, they develop a strong bond that might turn into a yaoi - like relationship. They learn from each other's strengths and weaknesses, and together, they become an unbeatable force.
You could also create a scenario where a curse has been placed on both of them that links their fates. In order to break the curse, they need to understand each other completely. So, they start spending a lot of time together, sharing their stories, fears, and hopes. This deep connection could then evolve into a yaoi relationship. Harry's experience with the wizarding community and El Tigre's experience with his family and the city he protects all play a role in how they interact and fall for each other.
One possible plot could be that Manny and Zoe are paired up for a school project. At first, they bicker and have different ideas on how to approach it. But as they start working together, they discover they have more in common than they thought. For example, they both love exploring the old parts of the city. This shared interest brings them closer and they become good friends, and eventually, there are some budding romantic feelings between them.
One common theme is the clash of different cultures. When El Tigre crosses over, he brings his own cultural background, like the Mexican - inspired setting of his original story, and it clashes or blends with the new world he enters.
One aspect is the potential for new magical abilities or characteristics. Since gargoyles are often associated with protection and mystery in architecture, in this fanfiction, they could have unique magical powers that interact with the magic in the Harry Potter world. This could lead to exciting plotlines, like a gargoyle - wizard team - up to solve a mystery or fight a dark force. The yaoi element also adds a different layer of emotional depth and relationship - building that can make the story more engaging.
Friendship or partnership is likely to be a theme. They might be portrayed as allies working towards a common goal in many fanfictions. This could involve things like saving their world or a particular community within it. Another possible theme is the exploration of their individual powers and how they complement each other when combined. For example, if one has a certain strength and the other has a unique ability, the fanfiction could play around with how they use these in unison. Also, there could be themes of self - discovery, where through their interactions, they learn more about themselves.
One plot idea could be a time - travel scenario where Harry goes back in time and meets a young Tom Riddle. He tries to change Tom's path to prevent him from becoming Voldemort. Another could be a situation where they are magically bound together and have to learn to co - exist and understand each other's motives.
One interesting story could be about Kal El arriving at Hogwarts and having to adapt to the magical world while still having his Kryptonian powers. Maybe he becomes friends with Harry Potter and they go on adventures together, using their combined powers to face new threats in the wizarding world.
One interesting idea could be the combination of magic systems. In 'Harry Potter', there's wand - based magic, while in 'Bleach' there are spiritual powers. Maybe in the fanfiction, characters from both universes learn to use the other's power source. For example, Harry Potter could learn to use reiatsu (spiritual pressure from 'Bleach') to enhance his spells, or Ichigo from 'Bleach' could learn how to use a wand to focus his spiritual energy in a new way.
One idea could be a story where a character from Harry Potter accidentally travels to the Hearime world and has to adapt to its unique magic system. They could learn new spells and make friends with Hearime characters while trying to find a way back to their own world.
One idea could be a crossover where Noctis visits Hogwarts. He could be mistaken for a new kind of wizard with his unique powers. Maybe he gets sorted into a house, like Gryffindor for his bravery, and then he has to learn about magic in the wizarding world while also sharing his own skills with the students.
