Another idea is that Eric and Ariel start a school where mermaids and humans can learn about each other's cultures. It could be full of comical misunderstandings at first, but as they work through these issues, their bond as a couple strengthens. There could be sub - plots about students from both sides falling in love as well, mirroring Eric and Ariel's relationship.
A plot could revolve around Prince Eric and Ariel having a misunderstanding. Ariel misinterprets something Eric does and runs away to the ocean again. Eric then has to go on a journey to find her and prove his love. He faces many challenges in the underwater world, which he's not used to, but his love for Ariel drives him forward.
One idea could be that Ariel and Eric are taking their baby on a magical underwater tour to introduce it to all of Ariel's friends in Atlantica. Another could be the baby showing signs of having both human and mermaid/merman powers and Ariel and Eric trying to figure out how to help the baby control them. Maybe there's a plot where an old enemy of Ariel's resurfaces and they have to protect their baby from this threat.
One idea could be that Ariel and Prince Eric go on a journey to discover a new underwater kingdom together. This would involve Ariel showing Eric all the unique and magical creatures she knows, and Eric using his human knowledge to help them navigate any challenges they face along the way.
One idea could be that Male Ariel, with his merman charm, saves Eric from a different sea - based danger than in the original story. For example, a sea monster created by an evil sea witch. Another plot could be Male Ariel and Eric going on an adventure to discover a hidden underwater kingdom that was lost in time. And perhaps they have to overcome some cultural differences between the human and merman worlds to be together.
One plot idea could be that Ariel has some unique challenges during her pregnancy because she is a mermaid in a human world. For example, she might struggle with the differences in medical care. Another idea could be that Eric is overly protective and Ariel has to balance his protectiveness with her own desire for independence. They could also face some opposition from the kingdom's council who are not sure about having a half - human, half - mermaid heir.
Well, a plot could revolve around Prince Eric being curious about the male Ariel's voice. In the original story, Ariel's voice was a big deal, and here it could be too. Maybe Male Ariel has a special song that only Eric can hear. Also, they could go on adventures together, exploring uncharted parts of the ocean. This would bring them closer as they face various sea creatures and challenges. And perhaps there's a conflict where Eric has to choose between his duty to his kingdom on land and his love for Male Ariel. This would create a lot of drama and tension in the fanfiction.
One idea could be that Ariel and Eric go on a magical underwater adventure together. They discover a new part of the ocean that has been hidden for centuries, filled with strange and beautiful creatures. Another could be that they face a threat to their kingdoms and have to work together to overcome it, using both their land and sea knowledge.
One idea could be that Darkseid tries to corrupt Supergirl in a non - physical, more ideological way. He might tempt her with power and a different view of the universe. For example, he shows her how the current state of the universe has flaws and that his way could 'fix' it. Supergirl, of course, has to resist this temptation using her strong moral compass.
Perhaps in the fanfiction, Ariel and Eric get married and have to deal with the cultural differences between the underwater world and the human world. For example, Ariel has to learn the proper etiquette in Eric's kingdom while Eric tries to understand the unique traditions of Ariel's mermaid family.
One idea could be Chuck's adventures in a new high - tech world where he uses his unique skills in a non - violent and positive way. For example, he could be part of a team that develops new security software using his knowledge of both the spy world and computer technology.
