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

One idea could be that the two teams are forced to compete in a series of challenges by a mysterious villain. This would lead to some friendly rivalries and also force them to learn from each other's strengths. For example, the Teen Titans' experience with magic-based threats could help the Young Justice team, while Young Justice's strategic planning might be beneficial to the Titans.

A cool Teen Titans Go fanfiction idea could be centered around a holiday. For example, during Christmas, a villain tries to steal all the presents in Jump City. The Teen Titans have to not only stop the villain but also make sure the city still has a great Christmas. Another idea is a fanfiction where Raven gets amnesia. The other Titans have to help her regain her memories while also protecting her from those who might take advantage of her in this vulnerable state. And then there could be a fanfiction where Beast Boy discovers a new animal form that he can't control at first, and the Titans have to help him master it.

One idea could be a crossover with the Justice League. The Titans could team up with the League to fight a powerful, universe - threatening villain. For example, Darkseid could be the main antagonist. The different powers and personalities of the Titans and the League members would create a lot of interesting dynamics.

Well, perhaps in the 'teen titans time loop fanfiction', there is a situation where the Titans are trapped in a time loop that is caused by an ancient artifact. They keep going back to a moment just before a huge battle. In each loop, they gradually discover new abilities or secrets about the artifact that could help them break free. Some Titans might also experience personal growth during these loops as they face their fears over and over again.

One idea could be the OC having unique powers that attract the Teen Titans in different ways. For example, if the OC can manipulate emotions, it could create complex relationships within the harem. Another plot could involve the OC coming from a different dimension and having to adapt to the Teen Titans' world while building relationships with them. Maybe the OC has a secret mission that the Teen Titans gradually discover as they get closer to the OC, adding an element of mystery.

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.

A fanfic could focus on Cindastar's backstory. Maybe she has a hidden past that is somehow connected to an ancient prophecy. As the story unfolds, the Teen Titans help her uncover the truth about her origin.

One idea could be creating an OC with a unique power like the ability to control time in small increments. This OC could be from a different dimension and end up joining the Teen Titans by accident. Their time - controlling power could cause all sorts of chaos and interesting plot twists as they learn to control it and use it for good.

One interesting plot idea could be exploring the backstories of the Teen Titans in more depth within the context of this fanfiction. Maybe delving into how they first discovered their powers and how it shaped their relationships.

A really interesting plot could be that there is a prophecy on their home planet that only Starfire and Blackfire together can fulfill. It involves finding a lost relic that has the power to save their planet from a looming disaster. As they search for the relic, they face many challenges that test their relationship and force them to rely on each other's strengths.
