You could also set the fanfic in a future where technology has advanced in Aphmau's world. The next - generation characters might have to adapt to these new technological changes while still holding onto the values of their community. This could lead to conflicts between the old - fashioned and the new - fangled ways of doing things, with the characters caught in the middle, trying to find a balance.
Another interesting concept is exploring the relationships between the next - generation characters. For example, how they deal with the legacies of their parents while trying to form their own identities. They could have different opinions on how to uphold or change the traditions of their families and the town. Also, a love triangle among them could add some drama to the fanfic.
One idea could be that the next - generation Avengers have to face a new villain who has the power to manipulate time. They must travel through different eras to stop the villain from changing key events in history that would lead to the destruction of the world as they know it.
Another interesting plot could be about a rift within the next - generation ninja community. Some might believe in following the old ways strictly, while others want to modernize ninja techniques. This conflict could lead to internal battles and eventually a realization that a balance between the old and new is necessary for the future of the ninja world.
One idea could be a time - travel plot. The main character goes back in time to the early days of Aphmau's world and has to navigate the different events without changing the future too much. Another idea is a 'what - if' scenario, like what if Aphmau never became a lord? They could explore how the different characters' lives would be different.
One idea could be exploring the friendship between the children of different Hogwarts houses. For example, the son of a Gryffindor and the daughter of a Slytherin becoming best friends against all odds. Another could be a new dark threat emerging and the next generation having to use new spells and magic they've developed. Maybe they discover a hidden chamber in Hogwarts that has secrets about the founders that no one knew before.
One idea could be the new generation facing a more powerful and evolved version of XANA. Maybe they have to figure out new virtual abilities to combat it.
One idea could be the children of the original students having to face a new threat in the classroom. Maybe a relative of Koro - sensei who has a different teaching style but also a hidden, dangerous side.
One idea could be the introduction of new alien species that the Star Fox team has to face. For example, a race of energy - based beings that can manipulate space - time. Another could be a story where the younger generation of the Star Fox team has to prove themselves to the older members. Maybe they get into a difficult mission where their new and untested skills are put to the ultimate test.
Begin by brainstorming different scenarios that could happen in the next generation. It could be something as simple as a new festival in the town or as complex as a political upheaval. Consider the relationships between the new characters and how they interact with the legacy of the previous generation. For example, if a character's parent was a great warrior, how does that affect their own path? Do they feel pressured to follow in their footsteps or do they want to carve out their own identity? Write down all these ideas and start building your story from there.
One idea could be that the new generation faces a school crisis, like a strict new rule that they think is unfair. They could start a peaceful protest to change it, just like the old characters might have.
One idea could be a story where Aphmau and Gene have to team up to save their town from a mysterious dark force. They start off as enemies but gradually learn to trust each other during the adventure.
