Perhaps the female squire is an outcast in the knightly community because of her gender. Kel Neal, however, believes in her potential. They start a training program that is different from the traditional ones. The female squire then discovers a long - lost technique that could change the way knights fight. But she has to overcome the prejudice of the other knights and with Kel Neal's support, she manages to introduce this new technique.
For Kel Neal, you can develop his character by showing his past experiences that made him the knight he is today. Maybe he had a tough mentor, and he doesn't want to be like that with the female squire. For the female squire, start with her dreams and fears. If she dreams of being a great knight, show what she's willing to sacrifice for it. Her fear of not being accepted can be a driving force for her character development.
Maybe Neal is on a quest to find something that he believes Snow and Charming can help with. Their meeting could be a bit tense at first as they don't know each other well. But as they start to talk, they realize they have a common enemy. So they form an alliance and during their journey, they learn about each other's pasts and grow to respect one another.
Perhaps they could go on a road trip together. Along the way, they encounter various challenges like getting lost, running out of money, or having car troubles. Through these experiences, they learn more about each other and their friendship deepens. It could also involve them meeting interesting characters during the trip who change their perspectives on life.
One idea could be the next generation facing a new, more powerful enemy that combines the powers of all the previous villains. They'd have to learn from their parents' stories and develop new skills to defeat it.
A plot idea could be that the next generation of Miraculous holders has to team up with some of the old villains' descendants who are now on their side. They have to overcome the prejudice from the public who don't trust them. Together, they work to stop a new evil that is threatening to destroy the balance between the Miraculous powers and the normal world.
One idea could be focusing on the children of Naruto and Hinata. Maybe their son has to deal with a new and powerful enemy that is targeting the Uzumaki clan. He could discover some long - lost jutsu that his father didn't know about and use it to defeat the foe.
One idea could be about a new type of Pokemon that emerges in the next generation. Maybe it's a fusion of two existing types due to some strange environmental phenomenon. Another could be a story where the main character is a descendant of a famous Pokemon trainer from the previous generations and has to live up to their legacy while facing new challenges in the Pokemon world.
Another plot could involve the next - generation Avengers having to prove themselves to the world. The public is skeptical of them at first, thinking they can't live up to their parents' legacies. So they take on a mission to save a major city from a powerful alien invasion, and in the process, they gain the public's trust.
Another plot could revolve around the relationships between the children of the original RWBY characters. For example, if Ruby's daughter has a different view on hunting Grimm compared to her mother. It could lead to internal conflicts within the new team and also show how the world has changed since the first generation's time. There could be political aspects too, like new laws regarding Huntsmen and Huntresses that they have to navigate.
One plot idea could be that Hadrian Potter discovers a way to enter Neal Caffrey's world (the non - magical world of White Collar). He then tries to help Neal solve a case using his magical abilities, but has to be careful not to expose magic. Another idea is that Neal Caffrey somehow ends up in the wizarding world and Hadrian has to show him around and protect him from the dark forces there while Neal uses his street - smart skills to help Hadrian in return.
