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.
Well, one possibility is that the other members of Young Justice immediately start a search and rescue mission. They might use their unique skills and powers to track Robin down. For example, Superboy could use his super strength to break through any barriers in their way, while Miss Martian could use her telepathy to try and sense Robin's location. Another scenario could be that Robin manages to escape on his own using his wits and combat skills. He's been trained well by Batman, so he might be able to outsmart his captors.
When Robin falls asleep in Young Justice fanfiction, he might be visited by a mysterious figure in his dreams. This figure could be a past hero or villain, or even a manifestation of his own subconscious fears or desires. The encounter could then set the stage for a new adventure or self - discovery for Robin once he wakes up.
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.
Well, perhaps the other characters in the Young Justice universe might take advantage of Captain Marvel being asleep. They could play a prank on him or have a serious discussion about what to do with him while he's out. Maybe they'd try to figure out if he's in some kind of danger that caused him to fall asleep suddenly.
Well, one possibility is that Tim Drake might be extremely grateful and form a new alliance with Red Hood. This could lead to them working together to take on a bigger threat in the Young Justice universe. Maybe they'd start sharing intel and resources that they each have access to, which could give them an edge against their enemies.
Well, it could be really interesting. They might be amused by some of the creative interpretations in the fanfiction. Some might find it strange to see their own characters in different scenarios that the fans have come up with.
Some members of Young Justice could be embarrassed. For instance, if there are romantic fanfictions about them that are a bit too cheesy or if their weaknesses are overly emphasized in a not - so - flattering way. But others might be really intrigued and want to explore more of what the fans think about them.
One great 'Young Justice Dimension: Justice League' fanfiction is 'The New Recruits'. It focuses on how new members are integrated into the team. The story has great character development and exciting action scenes.
