What are some interesting plot ideas for a Teen Titans Young Justice crossover fanfiction?

One idea could be a misunderstanding that leads to a battle between the two teams. Maybe a villain manipulates information so that the Young Justice team believes the Titans are up to no good. Then, as the fight unfolds, they start to realize they've been tricked.

One idea could be a crossover with the Justice League. The Teen Titans could team up with the big - league heroes to face a powerful, universe - threatening villain. For example, Darkseid could be the main antagonist, and the Titans' unique powers and youthful energy would add a fresh dynamic to the fight.

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.

Robin from Teen Titans and Robin from Young Justice would definitely have an interesting interaction. They both have leadership roles and similar names, but their leadership styles might be different. They could compare notes on leading their respective teams and learn from each other.

A more complex plot could be that there is a prophecy in both universes that foretells of a combined force from both Naruto's world and the Young Justice world being the only thing that can stop an upcoming great evil. This would lead to a series of events where characters from both sides have to learn to trust and work together. Naruto could bring his friends from Konoha, and together with the Young Justice team, they would train and strategize to face this ultimate threat.

One idea could be that the Outsiders are called in to help the Young Justice team when a new, powerful and mysterious villain emerges. This villain has a unique power that neither team has faced before, forcing them to combine their skills and resources.

One idea could be that the Young Justice team has to prove themselves to the Justice League during a major alien invasion. The League initially doubts their abilities but as the battle progresses, they see the unique skills and teamwork of the young heroes.

One idea could be that Ghost Rider's powers are somehow needed to stop a demonic threat in the Young Justice universe. Maybe a powerful demon is causing chaos and the team realizes they need the unique abilities of Ghost Rider to send it back to hell. Another plot could involve a member of Young Justice being possessed and Ghost Rider having to help exorcise the demon while also teaching the team about the darker, supernatural side of their world.

A cool plot could be a time - travel related crossover. The Young Justice team travels back in time and meets the younger versions of the Justice League members. They have to work together to stop a time - traveling villain from changing history in a way that would destroy the future. Or perhaps there's a magic - based crossover where a powerful sorcerer is causing chaos. The Justice League, which is more used to physical threats, has to team up with the Young Justice, some of whom have magic - related powers, to defeat the sorcerer.

One idea could be Raven struggling with her powers in a new way. Maybe there's a spell that backfires and gives her a strange new ability that she has to learn to control. This could lead to some comical situations as well as some self - discovery for her character.
