By adding unique twists to the story. For instance, instead of a normal pregnancy, it could be a magical pregnancy with special powers or abilities that come with it. This would add an element of fantasy and make the fanfiction stand out.
Involving more characters and their reactions in a detailed way can make it more interesting. Show how different characters like Yoshi or the Koopalings respond to Mario's situation. Their interactions and the dialogues can bring more depth to the story. Also, exploring different emotions like Mario's fear, excitement, and the support from his friends and family can make it engaging. For example, Luigi could be nervous for his brother but also excited to be an uncle. Princess Peach could be giving Mario advice based on her own experiences in the Mushroom Kingdom. This complex web of relationships and emotions would make the pregnant Mario fanfiction more interesting.
You can add some mystery, like not revealing who the father is right away. This will keep readers guessing. Also, include some emotional turmoil, like Gwen's fear of being a good mother. Drama always makes a story more engaging.
We can focus on the idea of new beginnings. For example, Mario discovers a magical seed that is 'pregnant' with the potential to grow into a huge, amazing tree that will bring new life and resources to his world. He has to protect it from the bad guys and help it grow, which makes for an exciting adventure.
Adding vivid descriptions can make it more engaging. For example, describe the feeling of the kicks as gentle thumps or sudden jolts. Also, include the emotions of the mother, like her excitement or a bit of nervousness. Another way is to create a unique setting, such as the mother being in a beautiful garden when she first feels the strong kicks.
Add complex characters. For example, introduce a new villain who is behind the hypnosis and has a deep backstory. This gives more depth to the plot.
One way to make Chunin more interesting in Naruto fanfiction is by giving them unique jutsu. For example, a Chunin could have a jutsu that manipulates the environment in an unexpected way. This would make their battles more exciting.
One way is to add a common enemy. By introducing a powerful foe that both Naruto and Rias have to face together, they can gradually overcome their initial hatred. For example, a new, extremely powerful demon or a group of rogue ninjas that threaten both their worlds.
By adding more characters from both universes. For example, having Sasuke interact with Stocking's sister Panty could bring in a whole new dynamic.
One way is to give more backstory to why he's a jerk. Maybe he had a tough upbringing or some sort of betrayal in his past.
One way to make it more interesting is through the use of different settings. Instead of just the usual Hogwarts setting, take the characters on an adventure outside, like to a magical forest or an ancient wizarding ruin. Daphne's possessiveness could play out differently in these new and dangerous environments. For example, she might be more overprotective because of the unknown threats, or her possessiveness could lead to her making a mistake that endangers them both. This would add excitement and novelty to the fanfiction.
One way to make it interesting is by exploring the cultural clashes. Naruto comes from a world of ninjas with a strict code and honor system, while Supergirl is from a world of superheroes with different values. The pregnancy could be a catalyst for them to find common ground. Another aspect could be the power combination of their child. What kind of abilities would it inherit? This mystery could keep readers engaged.
