Who would be the most interesting character pair in a Mako Mermaids meet H2O fanfiction?

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.

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.

Hulk and a mermaid with strong physical abilities. The Hulk is all about brute strength on land, and the mermaid could have enhanced strength in the water. Imagine if they had to work together to move a huge object that was blocking a passage underwater or on land. The mermaid could use her fins and water currents to help guide the Hulk's massive strength in the right direction, and the Hulk could protect the mermaid from any threats on land.

Zane would be a great character to include. He has his own charm and knowledge of the human world. If he were in a crossover, he could introduce new technology or ideas to the other mermaids. For example, if he crossed over with mermaids who are more primitive in their ways, he could help them modernize their defenses against threats. And he could also learn a lot from their ancient magic and traditions.

Edward and Cleo would also be a fascinating pair. Edward's brooding and mysterious nature combined with Cleo's kind - hearted and sometimes naive mermaid self could lead to some really interesting interactions. Maybe Edward could be intrigued by Cleo's water - based powers and Cleo could be both scared and attracted to Edward's vampire side.

I think pairing Hermione with one of the H2O girls would be really interesting. Hermione is so studious and knowledgeable about magic, while the H2O girl has her own unique water - related powers. They could learn a lot from each other. For example, Hermione could try to figure out the scientific basis behind the H2O girl's powers, while the H2O girl could show Hermione some new ways to interact with water magically.

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.

I think Chase from 'Lab Rats' and Jack from 'Kickin It' would be an interesting pair. Chase is the smartest of the bionic siblings and Jack is quite street - smart in the karate world. Their different ways of thinking and approaching problems would create a lot of interesting interactions. For example, Chase might be too reliant on his bionic intelligence, while Jack would show him how to use intuition and quick thinking in a fight.

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.

In my opinion, Black Widow and Annabeth Chase would make an interesting pair. Black Widow is a highly skilled spy and fighter, while Annabeth is known for her intelligence and strategic thinking. They could team up to outwit their enemies. Annabeth could learn some new combat moves from Black Widow, and Black Widow could gain insights into ancient strategies from Annabeth.
