A plot could involve Storm accidentally getting her powers out of control in Beast Boy's territory. Beast Boy then tries to help her regain control while also protecting the local wildlife from the chaos of her powers. It would be a story of friendship and understanding between two very different characters.
One interesting plot could be baby Beast Boy's first encounter with other Titans as a baby. Maybe he accidentally turns into different animals and causes chaos in the Titans' tower in a really cute way.
Another plot could involve Beast Boy getting lost in an alternate dimension in the fanfiction. He has to find his way back home while encountering strange creatures and new versions of his friends. This would test his survival skills and his loyalty to his original team as he might be tempted by the different relationships he forms in this new dimension.
One possible fanfiction could involve Beast Boy and Storm meeting in a multiverse scenario.

One interesting plot could be Beast Boy trying to balance his relationships with different characters in the harem. For example, he might have to deal with their different personalities and needs.

One interesting plot could be Beast Boy traveling back in time to the era of dinosaurs. He could use his shape - shifting abilities to interact with the prehistoric creatures. Maybe he tries to prevent an extinction - level event that could have a major impact on the present day. Another plot might be him traveling to the future and seeing a world where all the Titans have disbanded and he has to figure out what went wrong and how to fix it. And a third plot could be traveling to a key moment in the history of his own powers, like the origin of his shape - shifting abilities, and changing something that gives him new and different powers when he returns to his own time.
Perhaps in the fanfiction, the pregnancy could be a result of some sort of magical or alien interference. This would add an extra layer of mystery and adventure.

A Beast Boy x Storm fanfiction could center around a crossover adventure.

One interesting plot could be a new trainer's journey in the Pokemon Storm world, facing unique challenges and befriending rare Pokemon.

In the 'beast boy dominates raven fanfic', it could be that Beast Boy dominates in the emotional aspect. He might be the one to break through Raven's emotional barriers, being more in touch with his own feelings and using that to help Raven open up. This could involve him sharing his own experiences of loss or self - discovery, which in turn makes Raven more vulnerable and allows for a deeper connection between them.
One idea could be that Beast Boy and Storm meet during a strange weather phenomenon caused by a new super - villain. Beast Boy, being able to transform into various animals, could use his abilities to help Storm, who controls the weather, to combat the villain. For example, he could turn into a flying creature to help her reach the source of the abnormal weather in the sky.
