What could a 'Harry Potter H2O Crossover Fanfiction' be about?

I think the H2O mermaid, Rikki, could be a great focus. She's feisty and independent. If she were to meet Harry Potter, she'd probably be both intrigued and a bit skeptical of his magic. Her interactions with the wizarding world characters would be full of drama and discovery as she tries to understand this new and strange magic.

Love and relationships are also popular themes. The h2o characters might fall in love with characters from the other crossover story. This could create interesting relationship dynamics and storylines, like a mermaid falling for a human from a different fictional world.

Definitely Iron Man from the Avengers. His high - tech suit and intelligence could be really interesting when combined with the water - based powers of the H2O mermaids. And one of the mermaids, like Rikki, could be a main character too. She's feisty and her power to boil water could create some really cool interactions with Iron Man's technology, like powering up some of his systems in a unique way.

Maybe a magical item gets lost that is crucial to both the H2O and Mako Mermaids' worlds. It could be a pearl that has the power to keep the balance of the ocean's magic. A young mermaid from H2O and a young mermaid from Mako accidentally cross paths while looking for it. At first, they are suspicious of each other. But as they search together, they start to understand each other's powers better. The H2O mermaid can freeze water to access hidden caves, while the Mako Mermaid can use her singing to call upon sea creatures to help. Eventually, they find the pearl and in the process, they create a friendship that bridges the gap between their two worlds.

Well, it's a fanfic that crosses over 'Voltron' and 'H2O'. Maybe it has the technology from 'Voltron' showing up in the underwater world of 'H2O'. Or perhaps the characters from 'H2O' end up helping the 'Voltron' team in some way. It's really up to the creativity of the fanfic writer. They could be exploring how the different powers and personalities from both shows would interact and what kind of story could come out of it.

Once upon a time in the underwater world where the mermaids from H2O and Mako Mermaids co - existed. A group of mermaids from both series decided to have a friendly competition. The H2O mermaids showed off their unique ability to turn water into different shapes, while the Mako Mermaids demonstrated their incredible speed in the water. As they interacted, they learned new things from each other and became great friends, vowing to protect the ocean together against any threats.

In this fanfiction, the mermaids from H2O could be discovered by the Avengers. Maybe the Avengers are on a mission near the beach where the mermaids live. The mermaids' unique abilities, like controlling water, could be mistaken for a new threat at first. But then they realize they can work together. The mermaids could use their water powers to help the Avengers during a big battle against a water - based villain like Namor. They form an unlikely alliance and learn from each other's worlds.

Maybe the kiss is part of a spell or a curse. In the world of H2O, there could be some magical force at play. The kiss was meant to transfer powers or memories between them. So, instead of a normal romantic kiss, it becomes a catalyst for a whole new adventure or problem they have to face together.

Well, it could be a Harry Potter fanfiction that has something to do with a 36 - hour time frame perhaps. Maybe it's about an adventure that takes place within 36 hours in the Harry Potter universe. It could involve the characters facing a time - sensitive challenge or mystery.

One idea could be that the mermaids from H2O meet the vampires in Twilight. Maybe they form an unlikely alliance to fight a common enemy, like a group of powerful witches. The mermaids could use their water powers and the vampires their super strength and speed.
