There could be the children of the original Young Justice members. For example, a son or daughter of Robin who has inherited his detective skills and acrobatic abilities. They would be eager to prove themselves in the hero world.
New metahumans who have emerged in the time since the original team. Maybe a young girl with the power to control plants, who was inspired by the heroes she heard about growing up and now wants to join the new generation of protectors.
Gray and Juvia's offspring could also be central characters. They could have an interesting mix of ice - make magic and water magic. Maybe they struggle with controlling their powers at first, just like their parents did, but in different ways. And their relationships with the other next - generation characters could be complex, adding depth to the story.
There could be a character like Nova, a young girl who has the ability to phase through solid objects like a ghost but is human. She uses this power to help the new generation of ghost hunters.
The children of Natsu and Lucy would be great main characters. They could inherit their parents' powers and personalities. For instance, having the same determination as Natsu and the intelligence of Lucy.
Well, it could be the children of the original Loud House characters. For instance, Lincoln's son or daughter might be a main character, carrying on some of his traits like his leadership skills or his ability to handle a large family dynamic.
One idea could be exploring the new heroes' struggle to live up to the legacies of the original Young Justice team. They might face challenges like dealing with new villains who are specifically targeting them because of their predecessors. For example, a villain could try to recreate the same threats that the old team faced, but in a more modern and dangerous way.
Artemis might also be a part of it. She's a strong and independent character, and her dynamic with Superboy could add an interesting layer to the harem. Their interactions could range from friendly banter to more intense emotional moments.
Albus Potter is another obvious choice. As Harry Potter's son, he has big shoes to fill. In a time - travel story, he might travel back to understand his father better, or to fix a mistake that was made in the past that is now affecting the present wizarding world. He could also have some unique magical abilities passed down from his father that would come in handy during the time - travel adventures.
The children of Nagisa and Kayano could be main characters. They might inherit some of their parents' skills and quirks. For example, Nagisa's son could have his father's stealthy nature.
Well, it could include characters like Cassie Lang. Since she has shown an interest in following in her father's (Scott Lang) footsteps. She might be a key member of the next - generation Avengers in a time travel fanfiction. Another could be Kate Bishop. She has already proven herself as a skilled archer and fighter, and her abilities would be very useful in a time - travel adventure. And there's also Riri Williams, the young genius who could build amazing technology to help with the time travel and any problems they encounter in different time periods.
One popular character is Damian Wayne. As Batman's son, he often plays a significant role in the next - generation stories. He brings his own unique skills and a complex personality, having been trained by the League of Assassins. Another is Terry McGinnis from 'Batman Beyond'. He represents a future version of Batman and has his own set of challenges and relationships. Also, Cassandra Cain, with her exceptional martial arts skills, can be a prominent figure in these fanfictions, perhaps taking on a mentoring role for the new heroes.
