For Superman, you could explore his more human side. Maybe in this fanfiction, he's a bit more conflicted about his dual identity. Catwoman could be developed by showing her backstory more in - depth, like how she became a thief. When they interact, Superman's sense of justice could rub off on Catwoman, making her question her own actions, and Catwoman's free - spirited nature could make Superman loosen up a bit.
One common theme is the struggle of Superman to balance his heroic duties with his relationships in the harem. Another theme is the different personalities of the female characters in the harem and how they interact with Superman.
One popular superman harem fanfiction might be those where Superman has a group of female characters around him, like Lois Lane, Lana Lang and some other female superheroes. They often involve adventures and how Superman manages relationships with multiple female characters in a fictional setting.
I think a better approach would be to write a fanfic that focuses on the deep emotional connection between Superman and Wonder Woman without the 'lemon' elements. Their relationship could be explored in terms of mutual respect, shared values, and their roles as superheroes. This way, it can still be an interesting and engaging story while maintaining the integrity of the characters.
Lois Lane could be one of the characters. She has a long - standing relationship with Superman in the original lore, so she could be part of the harem. Then there could be other female superheroes like Wonder Woman. Her strength and noble character could make for an interesting dynamic with Superman in a harem setting. Also, Lana Lang from Superman's past could be included.
Well, a frequent theme is the concept of the extraordinary meeting the ordinary within the context of the harem. Superman is this super - being, and the harem members might be from different walks of life. This can lead to themes of self - discovery for both Superman and the harem characters. And of course, there's the theme of love triangles or more complex relationship webs. Since it's a harem, there are multiple characters vying for Superman's attention, which can create a lot of drama and tension in the story.

In fanfiction, their relationship can be developed by introducing a third - party threat that specifically targets their relationship. For example, a villain who tries to turn them against each other by spreading false rumors or creating misunderstandings. As they work through these issues, they come to understand each other better. Additionally, they could participate in joint training sessions. During these sessions, they can teach each other new techniques and improve their powers, all while building a stronger relationship.
