Imagine a fanfiction where Cleo and Lewis are in a bit of a dangerous situation. Maybe they are exploring an underwater cave and get trapped for a while. They start to worry but also realize how much they mean to each other. As they find a way out and reach the surface, they are so relieved and filled with joy that Lewis just grabs Cleo and kisses her passionately, a kiss that is a celebration of their survival and new - found closeness.
Well, in a fanfiction about Cleo and Lewis kissing, it might be that they've been through a lot of misunderstandings. They've been friends for a long time but there were always unspoken feelings. One day, after a big argument where they finally clear the air, they realize how much they love each other and that's when the kiss happens. It's a moment of truth and a new start for their relationship. This kiss could be the turning point that leads them to a more committed and loving relationship in the future of the fanfiction.
There were many animes that were similar to Summer Sunshine, such as Summer Sunshine (H2O)'s follow-up, Summer Sunshine Kiss (H2O-CHILI), Summer Sunshine's OVAs and theatres, and Summer Sunshine's manga.
No, H2O itself is not a cause of acid rain. Acid rain is typically caused by the presence of pollutants like sulfur dioxide and nitrogen oxides in the atmosphere.
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.
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.
Well, start with the OC. Decide if the OC is male or female, young or old. In an H2O and mermaid setting, perhaps the OC has some special connection to water. Maybe they are a scientist studying marine life. For the love story, introduce conflict. For example, there could be an evil sea creature that wants to keep the mermaid away from the OC. The mermaid and the OC then have to fight against this obstacle. Also, don't forget about the magic aspect of mermaids. They could have special powers like healing with their tears or communicating with sea animals, which can add an interesting layer to the love story.
