First, give each character a distinct personality. For the female characters in the harem, if Peach is part of it, she could be the elegant and diplomatic one. Daisy might be more of the spunky and adventurous type. The Toads could be the comical and helpful ones. Second, give them all individual goals. They shouldn't just be there for Mario, but have their own reasons for being in the group. For example, a Toad might want to learn more about magic from Mario's adventures.
For engaging characters, start with giving them distinct personalities. For a female character from the Brotherhood of Steel, make her highly disciplined but with a hidden soft side. Maybe she has a love for pre - war books. A raider girl could be tough on the outside but secretly long for a more stable life. Give her a backstory of being forced into raiding at a young age. And for a super mutant character, make her intelligent and philosophical, different from the typical brute - like super mutants. This way, their interactions with the main character and among themselves will be more interesting.
Another interesting concept is that the harem is formed due to a magical accident. Mario has to figure out how to reverse it, but in the process, he discovers that each member of the harem has a hidden power or ability. So instead of just trying to get rid of the situation right away, he decides to work with them to solve a greater threat to the Paper Mario world. The fanfiction could then detail their journey and the growth of their relationships.
First, give each character a distinct personality. For the female characters in Jaden's harem, one could be a fierce and competitive duelist, always challenging Jaden to improve. Another could be more of a strategist, offering him different ways to approach duels. By having these differences, they become more interesting and add depth to the story.
One way to create engaging characters in a My Hero Academia harem fanfiction is to give them flaws. No one is perfect, and this is especially important in a harem situation where there are multiple characters competing for attention. A character might be overly jealous, which causes problems in the harem. Another character could be too self - centered and have to learn to be more considerate of others' feelings. Also, you can introduce new aspects of their quirks. For example, a character with a super - speed quirk might also have a side effect that they have to deal with, like getting dizzy easily. This makes the character more interesting and relatable, and it also adds to the drama and intrigue in the harem.
Create backstories for the characters. The OC could have a troubled past that led them to Quahog. This backstory can influence how they interact with the harem. The female characters' backstories can also be tweaked slightly. For instance, if we consider Bonnie, her backstory could include a past where she was always overlooked, and now she sees the OC as a chance for attention. This would make her more desperate in the harem dynamic.
To create engaging characters, consider their cultural backgrounds. In an anime - inspired world, there could be different clans or kingdoms. If the OC is from a different place compared to the harem members, it can lead to cultural clashes and interesting exchanges. The harem characters can also have different skills. One could be a master of martial arts, another a great cook, and the third an expert in magic. These skills can be used in different situations, like when they all work together to protect the OC or compete for his affection.
Give each Pokémon in the harem a distinct personality. For example, a Charmander could be fiery - not just in its type but also in its temper. It could be quick to anger but also very loyal. The OC should have some unique traits too, like being able to sense when a Pokémon is in trouble from a great distance.
To create engaging characters, think about their abilities. If the OC has a power that is both useful and mysterious, like the ability to communicate with inanimate objects in Ooo, it will draw the attention of other characters. Their sense of humor is also important. If they can crack jokes in the Adventure Time style, it will make them more likable. For the harem aspect, make sure each character in the harem has a different reason for being attracted to the OC. For example, one might be attracted to the OC's intelligence, while another is attracted to their kindness.
For the predator, give it unique traits. Like a hawk that has a strange marking on its feathers which is seen as a sign of good luck among its kind. For the prey, make it have a strong will. For example, a mouse that is not afraid to stand up to a cat sometimes. This makes the characters more interesting.
For Bugs Bunny, you can explore his past more. Maybe he had a difficult time as a young bunny that made him so clever at escaping trouble. And for Lola Bunny, you can make her more complex. Instead of just being the athletic and confident character, give her insecurities. For example, she might be insecure about her looks sometimes. This makes her more relatable. Then, put them in situations that force them to confront these aspects of themselves. This will make the characters more engaging in the fanfiction.
