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.
Emma from H2O and Mimmi from Mako Mermaids would be an exciting pair. Emma is the smart and organized one in the H2O group. Mimmi is also intelligent but has a more free - spirited nature. They could work together to figure out some mystery in the ocean world. Maybe they find an ancient mermaid artifact and have to use their combined knowledge and skills to unlock its secrets.
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.
The plot could involve a mermaid from Mako getting lost and ending up in the area where the H2O mermaids live. The H2O mermaids would be surprised at first but then help the Mako mermaid find her way back. Along the way, they exchange stories about their experiences as mermaids, like how they got their powers and what they do to keep their identities secret. And in the end, they form an alliance of sorts.
In this fan fiction scenario, Nixie and Ben's reunion could be filled with a mix of emotions. Maybe Ben has changed since they last met, and Nixie is initially hesitant. They might meet at a place significant to their past, like the beach where they first interacted. The encounter could start off awkwardly, but then memories start flooding back, leading to a rekindling of their connection.
Perhaps Nixie has been away for a long time, and when she returns and meets Ben again, he has a new love interest. This creates a triangle of sorts. Nixie realizes she still has feelings for Ben, but she also respects his new relationship. Ben, on the other hand, is conflicted. He still has a soft spot for Nixie but doesn't want to hurt his new partner. This situation could lead to a lot of drama and self - discovery for both characters as they figure out what they really want.
One possible plot could be that the characters from Mako Mermaids end up in a different magical realm where they meet the mermaids from another story. They could team up to face a common threat, like an evil sea witch who is stealing the magic from all the mermaids. They would have to combine their unique powers, like the moon pool powers from Mako Mermaids and the special singing abilities of the other mermaids, to defeat the witch.
First, you need to create a well - developed OC. Think about their personality, backstory, and what makes them unique. For example, they could be a human with a special connection to the sea. Then, focus on how they meet Zac. It could be a chance encounter at Mako Island. Build their relationship gradually, adding in some conflict and resolution, like differences in their views on protecting the island's secrets.
A fanfiction on their kiss could show how it changes their relationship dynamic. For example, before the kiss, they might have been just friends or had some unspoken tension. But after the kiss, they have to deal with new feelings and how it affects their friends and the mermaid community around them.
Perhaps Mimmi gets hurt when she ventures too close to a human - made underwater structure that malfunctions. It could be an old, rusty oil rig with sharp edges. As she swims around it out of curiosity, a piece of metal could break off and scratch her tail, causing her pain and making it difficult for her to swim back home.
