What are some interesting ideas for a RWBY mass harem fanfiction?

One idea could be a crossover with another popular anime like Naruto. The RWBY characters could find themselves in the Naruto world and form relationships with the Naruto characters, creating a harem dynamic. For example, Ruby could befriend Naruto and his friends, and some of them might develop romantic feelings for her over time. Another idea is a crossover with a game world, such as the Elder Scrolls. The RWBY girls could explore the vast lands of Tamriel, meet different characters, and have a harem of followers or admirers from different races in the game. Maybe Weiss could attract the attention of some noble elves or powerful mages in Skyrim.

One idea could be that Naruto is somehow transported to the Mass Effect universe and his unique abilities draw the attention of various female characters. They see his determination and power as something new and exciting, leading to a harem situation. For example, characters like Liara might be intrigued by his chakra abilities which are completely different from biotics in their world.

Maybe a powerful and mysterious force affects the minds of some RWBY characters, turning them into yanderes for a particular character. This could lead to a lot of drama as they try to keep their yandere tendencies hidden while also vying for the object of their affection. For example, Ruby could be affected and her normally innocent nature takes on a more possessive and obsessive side when it comes to the person she loves.

One plot idea could be Cardin trying to balance his relationships within the harem. For example, he might have to deal with the different personalities and needs of each member. Another could be the harem facing a common enemy together, which would strengthen their bonds. Maybe there could be a plot where a new character enters the harem and causes some jealousy and drama among the existing members.

A possible plot is that in a mass harem fanfiction of Naruto and Percy Jackson, there is a competition among the harem members to gain the attention and affection of Naruto and Percy. This leads to some chaos and jealousy at first. However, Naruto and Percy work together to create a harmonious environment. They introduce their own cultures and values to the harem. Naruto shares the concept of ninja honor and Percy talks about Greek mythology and the importance of loyalty. As they do this, they also face external threats that require them to unite the harem and fight together.

One idea could be that Naruto, with his unique charm and ninja skills, attracts a group of female characters from different villages. For example, Hinata could be part of the harem, still being shy but deeply in love with Naruto. Sakura might also be there, having finally realized Naruto's true worth. And then add some new female characters from other lands, each with their own special abilities and personalities, and they all come together because of Naruto's heroic deeds and kind heart.

One idea could be that the OC reincarnates into the RWBY world with some unique powers from their past life. These powers attract the attention of different characters, gradually forming a harem. For example, their power could be related to some ancient magic that is both feared and desired in the RWBY world.

The gamer OC could be from our world and is somehow sucked into the RWBY world. In this new world, he realizes that his knowledge of games gives him an edge. He starts to form a harem as he helps the RWBY characters in different ways, like providing strategic advice during battles. For instance, he might suggest new ways to fight the Grimm based on his gaming experience. The relationships in the harem could develop as they train together and the OC shows his determination and kindness. Some characters might be initially skeptical of him but gradually warm up due to his positive influence.

One idea could be that the male reader is a transfer student to Beacon Academy. He has a unique Semblance that catches the attention of the RWBY girls. For example, his Semblance could be related to time manipulation. Ruby might be intrigued because she loves unique abilities and wants to learn from him. Weiss could initially be a bit standoffish but as she sees his skills and determination, she warms up to him. Blake would see something in him that reminds her of her own struggles, and Yang would be attracted to his confidence.

One interesting storyline could be about a character forming a unique bond with different species in the Mass Effect universe within the harem setting. For example, they might start with a relationship with an asari, exploring their long lifespan and biotic abilities. Then add a turian into the mix, dealing with the cultural differences and military discipline. Another could be a story where the protagonist has to navigate the political intrigue of the various alien races while maintaining their harem relationships.
