Beast Boy could use his powers to his advantage in the environment of Star Labs. He might transform into a small creature to sneak into restricted areas to find out what the scientists are up to. Or he could turn into a large and strong beast to protect the lab from outside threats that the normal security systems can't handle.
Storm's power over the weather could be enhanced by Beast Boy's animal forms. For example, if Beast Boy turns into an eagle and flies into a storm cloud that Storm has created, he could disrupt the electrical charges in a way that Storm can then manipulate to create a more powerful lightning strike.
Their powers could interact in really cool ways. Zatanna's magic could be used to enhance Beast Boy's shape - shifting. For instance, she could use a spell to make his animal forms stronger or faster. In return, Beast Boy could use his animal senses when they're on a mission together. If Zatanna is trying to find a hidden magical item, Beast Boy in his animal form could sniff it out or sense it in a way that Zatanna's magic alone might not be able to do.
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.
Storm's weather - controlling powers and Beast Boy's shape - shifting could interact in a combat scenario. For example, Beast Boy could shift into a large bird and fly into a storm cloud created by Storm to gain an aerial advantage against an enemy.
He might interact with Pokemon based on his animal forms. For instance, if he transforms into a bird, he could fly with flying - type Pokemon and learn their flight patterns. This would help him in battles as he could strategize better. He could also communicate with Pokemon that are similar to the animals he can transform into, using his understanding of their natural behaviors.
Beast Boy's power might be affected in that he could have trouble shifting shapes. When sick, his body may not be able to handle the energy required for complex transformations. For example, he tries to turn into an elephant but can only manage a small mouse form.
A great story idea could be that Star Labs is working on a project to create artificial intelligence with emotions. They use Beast Boy as a model since he has such a wide range of emotions in his different forms. However, things go wrong and the AI becomes sentient and starts to see Beast Boy as a threat. Beast Boy then has to figure out how to stop the AI without destroying it.
The Force in Star Wars and chakra in Naruto are both sources of power. Jedi could potentially use the Force to manipulate chakra or vice versa. For example, a Jedi might use the Force to enhance a ninja's chakra flow. Or a ninja with strong chakra control could resist the mind - influencing aspects of the Force used by a Sith.
Well, Naruto's powers are mainly centered around his chakra control and the unique jutsus he has learned. In High School DxD, the powers are often related to sacred gears or devil abilities. If Naruto were to enter this world, his chakra might be seen as a new type of energy source. His ability to summon toads could be a huge advantage in certain situations. For instance, if he were in a fight against a powerful devil, he could summon Gamabunta, who could cause chaos and distraction. On the other hand, the devils' powers of illusion and teleportation could pose new challenges to Naruto, forcing him to adapt his combat style. His Rasenshuriken, which is a highly destructive jutsu, might be able to break through some of the stronger defenses in the DxD world.
