Another plotline might be about a character who was on the outskirts of Young Justice, like a sidekick who was not fully integrated yet. This character could go on a journey to discover what really happened to Young Justice and in the process, find their own place in the hero world. They might uncover a conspiracy behind the deaths and have to fight against those responsible.
One possible plotline could be the remaining heroes dealing with the aftermath of a major battle where many Young Justice members were lost. They might struggle with guilt and the pressure to carry on the legacy.
Maybe there's a plot where they have to go undercover as a couple. As they pretend to be in love for the mission, they start to actually develop feelings for each other. The kiss could be a turning point where they admit their real emotions to themselves. For example, they might be infiltrating a villain's lair where only couples are allowed in, and during this time, their relationship deepens.
One possible plotline could be them teaming up on a mission. Maybe they are sent to a magical realm where Nightwing's combat skills and Zatanna's magic are both needed to defeat a powerful villain. For example, a sorcerer who is using dark magic to corrupt the land and its people. Nightwing could use his acrobatic skills to dodge attacks while Zatanna uses her spells to counter the sorcerer's magic. Another plotline could involve a mystery that they have to solve together. It could be related to a series of disappearances in a city, and they discover that it has something to do with a long - lost magical artifact that Zatanna has some knowledge about. As they work together, they might also start to develop feelings for each other, adding a romantic sub - plot to the story.
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.
A popular type of 'Dead Young Justice' fanfiction is one that gives a different perspective on a well - known event in the series. For instance, the events of a particular mission from the point of view of a side character. This can offer new insights into the story and the other characters' actions. There are also fanfictions that rewrite the whole story with a different starting point, like if the team was formed under different circumstances.
A possible plotline could be a training exchange. Naruto, being a highly skilled ninja, could offer his training expertise to the Young Justice team. They could learn things like stealth, chakra control (which could be translated into a form of energy control in the Young Justice universe), and hand - to - hand combat. In return, the Young Justice members could teach Naruto about modern technology and different forms of superpowers. This would create a great opportunity for character development and cultural exchange between the two universes.
Perhaps in this fanfiction, there could be a new, unexpected hero emerging. Maybe Neville Longbottom finally steps up in a big way. Since Harry is dead, Neville could be the one to find a new way to defeat Voldemort, like discovering a long - lost spell or uniting the houses in a way that has never been done before.
Perhaps Harry finds out that the Dementors were being misused by the Ministry of Magic. He then decides to demand justice for all those who were wrongly affected by the Dementors. He could fight to change the way Dementors are used in the wizarding world, or even find a way to rehabilitate them if possible. Or it could be that Harry uncovers a conspiracy within the Order of Phoenix where some members were acting for their own self - interests rather than for the greater good. He then has to hold those members accountable and restore the integrity of the Order.
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.
