A more complex plot could be centered around a prophecy that involves both the Titans and RWBY universes.

Along the way, they would face internal and external conflicts, as some might not believe in the prophecy, while others might try to use it for their own gain.
Another plot could involve a character from RWBY getting lost in the world of the Titans. They would have to figure out how to get back home while also dealing with the Titans' own set of problems, like the various villains and power struggles in that universe. This could lead to some interesting character development as they learn from each other's strengths and weaknesses.
One idea could be a crossover where the Titans characters end up in the RWBY world and have to adapt to the Grimm and Huntsmen system. Maybe they team up with Team RWBY to fight a new, powerful Grimm that's causing chaos across Remnant.

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.
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.

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.
