To develop characters interestingly in a Pokemon harem fanfiction, you can explore their fears. Maybe a certain Pokemon in the harem is terrified of water because of a past incident. The main character then has to help it overcome this fear. This process of facing and conquering fears can make the character grow. Another aspect is their cultural or species - specific traits. A Pokemon from a certain region might have unique customs or abilities. Incorporating these into their character development, like how they interact with the main character based on these traits, can make them really stand out.

The 'hate - sex' trope is quite common. They start off hating each other so much that the passion turns into a physical encounter that is initially more about aggression than love. Another trope is the 'forbidden love' aspect. Since they were enemies, their relationship is often frowned upon by their respective groups or families. There's also the 'slow burn' trope, where the transition from enemies to lovers is gradual, with lots of small moments of connection and growing attraction over time.

To write such a story, think about what could make them lose trust and respect for each other. It could be a life-changing event or a series of small incidents that accumulate over time. Also, show how their emotions change and how they struggle to deal with the transformation of their relationship.

You need to build up strong character conflicts at the beginning. Make their differences clear and intense. Then, introduce situations that force them to work together and gradually reveal their hidden commonalities and vulnerabilities.

Another great 'enemies to lovers' story is 'The Hating Game' by Sally Thorne. Lucy and Joshua work in the same office and they seem to be at odds all the time. They compete for the same promotion, constantly bicker and annoy each other. But underneath all that, there is an unspoken attraction. As they get to know each other on a deeper level during a business trip, their relationship changes and they realize they are in love.

One way is through a shared mission. They could be sent on a dangerous and secretive mission where they have to rely on each other. This would force them to understand each other better and build trust. For example, they might be sent to infiltrate an enemy stronghold where Naruto's stealth skills are put to the test and Anko has to use her knowledge of poisons and traps to get them through.

One important method is through dialogue. As they start to talk more, they begin to understand each other's motives and personalities. In some novels, a gradual revelation of the characters' true selves plays a big role. For instance, the 'enemy' might show a vulnerable side that the other character didn't expect. This can break down the barriers between them. Also, the setting can contribute. If they are in a new and unfamiliar place together, it can force them to depend on each other and change their relationship dynamic.
