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 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.
Obviously, the members of the Young Justice team would be the main characters. This could include Robin, who is known for his detective skills and acrobatics. He's a key figure in leading the team in many situations.
Perhaps there's a plotline where a new member joins the team during this 'in - heat' situation. They have to quickly adapt to the intense conditions and the team dynamics. The new member might have a power related to heat, like the ability to manipulate fire, but they first need to learn how to control it properly within the context of the team and the ongoing heat - related challenges.
A cool plotline might be Starfire's origin story in the context of Young Justice fanfiction. How she ended up on Earth and her journey before joining the team. It could involve her past relationships on her home planet and how they influence her actions on Earth. Also, a plot where she discovers a new power within herself while training with the Young Justice group, which then becomes crucial in a big battle against a supervillain.
Maybe in the fanfiction, Robin is misplaced in time rather than space. He could end up in the past, having to interact with younger versions of his teammates or even their predecessors, and has to use his wits to not disrupt the timeline while also finding his way back. This would involve a lot of character development as he sees his friends in a new light.
One interesting plotline could be the daughter's struggle to break free from her father's shadow. She might try to use her skills for good while everyone expects her to be like Deathstroke. For example, she could join the Young Justice team secretly and help them on missions, all while hiding her identity.
A great plotline could involve Superboy and Superman teaming up against a powerful new villain that neither could defeat alone. They would have to learn to work together and trust each other fully. This would show their different fighting styles and how they complement each other. For example, Superman's experience and calmness in battle could balance out Superboy's more impulsive nature.
One interesting plotline could be Robin trying to prove himself to Batman in a more complex and dangerous mission within the fanfiction world. Maybe there's a new villain in Gotham that only Robin can stop, but Batman is hesitant to let him take the lead at first.
One interesting plotline could be them having to deal with a new and powerful villain that specifically targets their relationship. For example, a villain who tries to turn them against each other by manipulating their past traumas. Another plotline might be them training a new group of young heroes in Young Justice together. It would show their different teaching styles and how they complement each other.
Some fanfictions might have a plotline where the team has to face an old enemy that has been resurrected or empowered by the events of Endgame. This could lead to intense battles and strategic planning. There could also be a story about the relationships between the characters evolving. For instance, romantic relationships might form or existing friendships could be tested as they all deal with the new world order after Endgame.
