A possible plot could be that there's some sort of interdimensional rift that brings Beast Boy and Storm together. They have to work together to close the rift while also dealing with their different powers and personalities. Beast Boy's ability to transform into animals and Storm's control over the weather could create some really cool action scenes as they face various threats.
Maybe there's a powerful villain who is stealing powers from both mutants and meta - humans. Beast Boy and Storm team up to stop this villain. Along the way, they learn from each other. Storm teaches Beast Boy more about controlling his emotions to better use his powers, and Beast Boy shows Storm how to have more fun and be less serious all the time. Their relationship could start as a reluctant partnership but grow into a strong friendship as they go through different challenges.
One idea could be a crossover adventure where Beast Boy and Storm team up to stop a powerful villain that threatens both their worlds. They could start off not trusting each other due to their different backgrounds, but as they face challenges together, they learn to respect and rely on each other's powers.
Beast Boy's power to transform into animals could complement Storm's weather - controlling abilities in many ways. For example, if they are in a battle and Storm creates a powerful windstorm, Beast Boy could transform into a bird and ride the winds to gain a strategic advantage. Or if they are in a desert environment, Beast Boy could turn into a camel while Storm creates a rain cloud to bring water.
Beast Boy's power to transform into animals could be affected by Storm's weather control. For example, if Storm creates a strong wind, it could either help Beast Boy fly faster in his bird form or make it difficult for him to stay in the air if he's not used to such strong winds. Also, if Beast Boy turns into a cold - climate animal like a polar bear, Storm could make the area around him even colder, enhancing his natural abilities in that form.
One possible plot could be that the Teen Titans and the X - Men are brought together by a common enemy. Maybe a powerful mutant - hating villain has created a device that can nullify mutant powers and is also targeting the Teen Titans' powers. The two groups would have to combine their unique skills. The X - Men with their long - experience in dealing with mutant - related threats and the Teen Titans with their fresh and energetic approach. They could start off distrusting each other, but as they face challenges together, they learn to work as a team.
