A different plot could involve the hometown girl being in some kind of trouble. Perhaps she's being bullied at school. The boys from 'Stand by Me' find out and decide to stand up for her. In the process, they all learn about loyalty and the importance of standing by those you care about. The girl then becomes an important part of their group, and they have a series of heart - warming and exciting experiences together.
To develop the characters, think about their backstories. The hometown girl could have a backstory of growing up in a big family where she often felt overlooked. This would explain her shyness. The boys from 'Stand by Me' could have their own backstories that are further explored in relation to the girl. For instance, one boy might have lost a sibling and the girl's presence helps him heal. Their relationships can be developed through shared experiences. They could all go on a camping trip and during that time, learn more about each other's fears, dreams, and secrets. This would make their characters more complex and interesting.
One idea could be exploring what would happen if the boys found a different kind of adventure, like stumbling upon a time - traveling device. Another could be a story where Gordie's writing takes him on a journey to a famous writing school in a big city, and his friends from Stand By Me support him in a whole new way. Or perhaps a fanfiction where the boys encounter a mysterious old hermit in the woods who has a deep and dark secret that they have to figure out.
One idea could be to focus on the backstories of the minor characters in 'Hometown Cha Cha Cha'. For example, exploring how the local fisherman got into his profession and his relationship with the main characters. Another could be a time - skip fanfic, showing what the characters' lives are like years after the events of the show. Maybe they have kids and are dealing with new challenges in the hometown.
For a crossover with 'E.T. the Extra - Terrestrial', the boys from 'Stand by Me' could stumble upon E.T. in the woods. They would then have to protect him from the government agents. This would bring a new level of adventure and a touch of sci - fi to the 'Stand by Me' world. They could also use their friendship and loyalty to keep E.T. safe and help him get back home.
One idea could be a new student arrives at the Gallagher Academy with a mysterious past and special skills that the other girls don't have. This new character could bring in a new set of challenges and friendships. Another plot could be a mission that goes wrong and the girls have to use their wits and training to get out of a tricky situation. Maybe they get trapped in an enemy's lair and have to find a way to escape while also gathering intelligence.
A 'volleyball girl fanfic' could focus on a transfer student who is a volleyball prodigy. She has to adjust to a new school, new teammates, and new coaching styles. Along the way, she forms deep friendships and rivalries, all while trying to help the team win the championship.
One idea could be a cat girl who discovers she has special powers and has to use them to save her city from an evil villain. Another could be a cat girl falling in love with a human in a world where such relationships are frowned upon.
One idea could be that as a girl, Ben has to face different social challenges while still using the Omnitrix to save the day. For example, some might underestimate her because of her gender, but she proves them wrong with her heroic deeds.
One idea could be a Lamia Girl who lives in a hidden forest and befriends a lost human adventurer. They help each other understand their different worlds.
One idea could be exploring new stand abilities inspired by RWBY characters' weapons or semblances. For example, a stand based on Ruby's Crescent Rose could have the ability to manipulate time briefly like Ruby can move at high speeds. Another idea is to create crossovers within the RWBY universe using stands, such as having a stand user from a different part of Remnant interact with the main RWBY team and their battles.
