A human noble who doesn't approve of Ariel and Eric's union and especially doesn't like the idea of a half - human, half - mermaid baby. This noble could try to create problems for the family, like spreading false rumors or trying to get the baby separated from its parents. Another possibility is a sea monster that has been awakened by the birth of the baby, seeing it as an intrusion in its territory and trying to harm the baby and its parents.
Their baby could look very much like a normal human baby at first glance, but on closer inspection, it has some mermaid - like qualities. For example, its ears might be slightly pointed like Ariel's, and when it's in the water, it seems to move with an unusual grace. It has a beautiful face with a combination of Ariel and Eric's best features, and its skin has a soft, almost iridescent sheen in certain lights.
Maybe the plot involves the baby getting kidnapped by an evil sea witch who wants to use the baby's unique heritage for her own dark purposes. Ariel and Eric then embark on a dangerous adventure to rescue their baby. Along the way, they meet various sea creatures and humans who either help or hinder them. In the end, they manage to save their baby through their combined strength and love.
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.
Fanfiction that involves sexual content, like 'ariel and eric sex fanfiction', is inappropriate. It objectifies the characters in an improper way. Instead, we should encourage fan - created works that are family - friendly and focus on aspects like their relationship in the context of the original story, like how they support each other and face challenges together.
One challenge could be the reactions of their families. Their families might have different expectations or concerns. Another could be the fear of the unknown, like potential problems during the pregnancy.
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.
There are also fanfictions where Ariel and Eric are shown as role models for the younger generation in their kingdoms. They could be teaching values like kindness, courage, and friendship to the children in their respective lands. This kind of fanfiction is great for family - friendly reading.
Family can be a theme as well. Their families play important roles in some fanfictions. Ariel has her mermaid family, and Eric has his royal family. Sometimes there are conflicts or reconciliations between their families that affect their relationship. And then there is the theme of sacrifice. They might have to sacrifice something for each other, like Ariel sacrificing her mermaid life to be with Eric, and in fanfictions, this concept can be explored in different ways.
Discovery is another theme. They are constantly discovering new things about each other, their cultures, and their worlds. This discovery process helps to strengthen their bond and is a key element in many ariel and eric lemon fanfictions. For instance, Eric might learn about the mermaid society from Ariel, and Ariel might learn about human traditions from Eric.
