A crossover involving a shared enemy. Maybe a new alien race that is a threat to both universes emerges. The combined forces of Babylon 5 and Star Trek would have to pool their resources. The Starfleet officers could share their scientific knowledge to analyze the new threat, while the Babylon 5 personnel could offer their street - smart combat and negotiation skills developed from their own experiences in the often - tumultuous Babylon 5 station.
Captain Kirk from Star Trek is often a popular choice. His bold and adventurous nature can add a lot of action to the crossover. He might be the one to initiate contact with Babylon 5 characters and lead the exploration of the new universe.
One interesting idea could be the interaction between the different alien species from both universes. For example, seeing how Vulcans from Star Trek would interact with the Minbari from Babylon 5. Maybe they would exchange knowledge on logic and philosophy.
A great storyline might involve a fusion of the two worlds' mechanics. For example, the Velvet Room from Persona could have some connection to Joker's world. The Igor-like figure could offer Joker and his friends some new kind of power or knowledge that they use to combat a common foe. Or perhaps the Persona characters learn about Joker's Metaverse Navigator and try to replicate it in their world, which leads to all sorts of unforeseen consequences and adventures.
Captain Kirk from Star Trek is often a popular character in these crossovers. His bold leadership style and charisma can bring a lot to the story. In Babylon 5, Sheridan is also a favorite. His ability to navigate the complex political situation in Babylon 5 can create interesting scenarios when paired with Star Trek characters.
The communication devices are another area. Star Trek's communicators are well - known. Babylon 5 also has its communication systems. In the fanfiction, they might try to integrate the two for better long - range and inter - universe communication. This could involve some technical difficulties as they have different frequencies and encryption methods, but it would be exciting to see how the characters overcome these challenges.
Another could be a time - travel scenario where Naruto goes back in time and meets Rikudou Sennin. They then team up to prevent a great evil from ever arising in the first place. This would allow for a lot of character development and exploration of the Naruto universe's history.
One of the most interesting storylines could be the interaction between the different species in Mass Effect and those from Stargate. For example, how would the Asari react to the Goa'uld? The Asari are a long - lived, biotic - using species in Mass Effect, while the Goa'uld are parasitic snake - like beings in Stargate. Another cool idea is the technology exchange. The Mass Effect universe has advanced biotic and cybernetic technology, and Stargate has its own unique wormhole - based travel and Ancient technology. A fanfiction could explore how these technologies might be combined or used against each other. Also, the cultural clashes would be fascinating. The different races in Mass Effect have their own moral and ethical codes, and the same goes for the races in Stargate. How would they deal with each other's values?
One interesting storyline could be Naruto using the Sharingan to enhance his combat skills in a new and unexpected way. For example, he might combine his Rasengan with Sharingan - powered genjutsu to create a more powerful and deceptive attack.
A really cool storyline might involve a powerful object or spell that links the two shows. For instance, a magical artifact in 'Supernatural' that can also affect the Wesen in 'Grimm'. The characters from both shows would have to race against time to find and control this object before it falls into the wrong hands. It would be a high - stakes adventure that combines the best elements of both shows, like the family - centered themes in 'Supernatural' and the unique fairy - tale inspired world of 'Grimm'.
Well, perhaps a story where the two characters cross paths due to a serial killer case. The killer seems to be targeting people involved in the legal system, and Perry Mason is representing some of the potential victims or suspects. Ironside gets involved as the detective on the case. Their different approaches at first clash but then they start to respect each other and combine their efforts to catch the killer. They might also discover a hidden conspiracy behind the killings.
