One idea could be a time - travel fanfiction. The Young Justice Team gets sent back in time to the early days of the Justice League. They have to work in secret to fix a disruption in the timeline without being detected by their heroes - in - training selves. This would create a lot of interesting scenarios where they see the origin of the League and try to blend in while on their mission.
A fanfiction about an alternate reality where the Young Justice Team has different powers. For example, instead of Superboy's usual strength, he has the power of telepathy. They would have to learn to use these new powers to fight against a familiar yet different set of villains. It could explore how their relationships and strategies change because of these power alterations.
You could write a fanfiction where the Young Justice Team has to go undercover in a high - school. They have to deal with typical high - school problems like bullies and exams while also secretly protecting the school from a hidden threat. This would add a touch of normalcy and humor to the story as they struggle to balance their superhero duties with their new 'teenager' identities.
One idea could be the team having to adapt to their new younger selves while still trying to fight crime. They might struggle with physical limitations that they didn't have before. For example, not being as strong or fast, which could lead to creative solutions in combat situations.
Another plotline might focus on the relationships within the team. For example, how two members who initially didn't get along start to understand each other better during a mission. This could involve them sharing their backstories and finding common ground.
One idea could be a crossover where the Young Justice team has to team up with the Justice League to face an interdimensional threat. Maybe a powerful villain from another dimension is trying to invade Earth and the combined skills and powers of both groups are needed to stop it.
Maybe a story where some of the younger members of the Young Justice team are frustrated with the Justice League's methods and decide to take on a mission on their own, but end up getting in over their heads and have to call in the League for help. This could lead to a lot of character development and some interesting dynamics between the two groups.
One idea could be Goku arriving in the Young Justice universe due to a rift in space - time. He could initially be confused but quickly adapt and start training the young heroes, sharing his Saiyan techniques like the Kaio - ken.
One idea could be exploring new character backstories. For example, you could delve deeper into the origin of a less - known character in the Young Justice Z universe. Maybe they have a hidden power or a tragic past that has yet to be fully explored in the existing canon.
A cool Young Justice gamer fanfiction could revolve around a game tournament. The heroes participate in a high - stakes gaming competition where the loser has to face some sort of consequence in the real world. This could lead to intense rivalries and strategic gameplay within the story. Also, a story where the team discovers a hidden game level that holds secrets about their past or future could be really engaging.
One interesting idea could be the role reversals in relationships. For example, if in the original a male character was the leader, in the genderbend fanfiction, a female character might take on that role. This can lead to new power dynamics and character interactions.
One idea could be exploring the backstories of the lesser - known members in more depth. For example, you could focus on a character like Blue Beetle and his struggle to control the Scarab while also fitting into the team. Another idea is to create an alternate universe where the Justice League is evil and the Young Justice League has to oppose them. This would lead to some really intense battles and moral dilemmas for the young heroes.
One idea could be a crossover where characters from Arrowverse and Young Justice have to team up to stop a multiverse - threatening villain. For example, Green Arrow and Nightwing leading the combined forces.
