In the fanfiction, Beast Boy could be on a personal mission within the Young Justice group. Maybe he's trying to find out more about his powers' origin and believes that the team's resources or connections can help him. As he delves deeper, he discovers a hidden conspiracy that not only affects him but also the entire Young Justice team, leading them all on a dangerous adventure to uncover the truth.
Beast Boy could start off as a bit of an outcast on the team. He's used to being with the Titans, so he has to learn new strategies and ways of working. His character could develop as he overcomes his insecurities and shows his true worth to the Young Justice members. For example, he could learn to control his powers better in high - stress situations.
There might be a fanfiction where Raven and Beast Boy swap powers for a day. This would lead to some really funny and also challenging situations. Beast Boy, with Raven's powers, might struggle to control the dark energy, while Raven, in the form of different animals, could have a hard time adapting. It would also show how they understand each other's abilities better. Also, a story where they have to protect a small village together and in the process, they learn more about each other's pasts and grow closer.
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 that the Young Justice team gets accidentally transported to an alternate dimension where the Justice League has turned evil. The Young Justice members then have to figure out how to reverse the situation while also evading capture from their once - heroes. Another could be a time - travel plot where the Young Justice team travels back in time and teams up with the early days of the Justice League to stop a threat that was thought to be long gone but has resurfaced in their own time. A third idea is that a powerful new villain emerges who can only be defeated by a combined effort of the Young Justice and Justice League, but first they have to overcome their differences in fighting styles and leadership.
One idea could be a misunderstanding that leads to a battle. Maybe a villain manipulates the situation so that Young Justice thinks the Justice League has turned evil. For example, the villain uses mind - control technology on some of the League members and Young Justice has to fight to save them.
One idea could be a misunderstanding that leads to a fight. Maybe the Justice League mistakes some of Young Justice's actions as being too reckless and end up in a battle. Then they realize they were wrong when a real threat emerges and they have to work together.
Another plot could involve a new threat emerging that is related to the events of Endgame. The team has to piece together clues from the past events to stop this new danger. They might discover secrets that were hidden during Endgame that could change everything.
One idea could be a Young Justice member getting bitten and turning into a werewolf and having to hide it from the team at first. Another is a werewolf - based villain that the team has to face, who has some connection to an ancient werewolf legend in the DC universe. Maybe a story where a werewolf is used as a weapon by an evil organization against the Young Justice team.
A third plot idea might be a crossover with another DC property. Imagine the Young Justice team having to team up with the Teen Titans from an alternate universe. They would have to learn to work together despite their different methods and personalities, all while facing a common threat that is powerful enough to endanger both universes.
