Mass Effect has advanced AI in the form of geth and EDI. In a crossover, the technology of the Mass Effect universe could be combined with the eldritch knowledge of the Cthulhu Mythos. Maybe the geth, who are constantly evolving and learning, stumble upon Cthulhu Mythos knowledge and start to incorporate it into their programming. This could lead to them developing new forms of technology or behavior that are a blend of both universes, like creating constructs that have a disturbing, Cthulhu - inspired appearance but are powered by mass effect fields.
One way is through biotics. In Mass Effect, biotics are a form of biological manipulation of mass effect fields. Cthulhu Mythos entities often have strange, otherworldly biological features. Fanfiction could combine these by having a character gain new biotic abilities inspired by Cthulhu Mythos creatures. For example, instead of the normal biotic powers like lift and throw, a character might develop the ability to summon dark tentacles similar to those of a Cthulhu - like being.
The mass relay system in Mass Effect is crucial for interstellar travel. In a crossover fanfiction, the Cthulhu Mythos could be integrated into this. Imagine that the mass relays were actually built by an ancient race that was influenced by Cthulhu Mythos entities. The relays could have hidden functions or side - effects related to the Mythos. For example, when activated, they might sometimes open portals to other dimensions filled with Cthulhu - like horrors, or they could cause madness to those who use them without proper protection.
The energy shields in Halo could be combined with the natural defenses of Pandora. For example, the Na'vi could use the technology to create shielded areas around their sacred places. Also, the UNSC's weaponry could be enhanced with the unique materials found on Pandora. The super - strong metals there could make Halo weapons even more durable.
A really cool plot twist could be that the Protheans, who are an ancient and advanced race in the Mass Effect universe, had actually encountered Cthulhu Mythos entities in the past. This could explain some of the mysteries surrounding their downfall and the disappearance of their technology. Maybe they tried to harness the power of these otherworldly beings and it backfired, leading to their civilization's collapse. This revelation would not only change how we view the Protheans but also add a new element to the overall lore of the Mass Effect universe.
Another approach could be to bring a Harry Potter - like character into the Mass Effect Andromeda setting. This character could be a wizard who has to deal with the different species and technology. They might use their magic to solve some of the problems the Andromeda crew faces, like dealing with the Remnant or helping to heal the Initiative members in a way that normal medicine can't. They could also introduce the concept of magic to the Andromeda races, which would cause quite a stir.
In a fanfiction, the two universes' technologies could combine in terms of communication. The US soldier could introduce more advanced radio or communication devices. These could be used to better coordinate the huntsmen and huntresses in RWBY. Also, the soldier's knowledge of military engineering could be used to build stronger fortifications in RWBY settlements. This would help in defending against Grimm attacks. The soldier could also work on improving the airship technology in RWBY using some of the engineering concepts from the US military.
One way is through character interactions. For example, Shepard could team up with Ruby and they could share their combat experiences. Shepard's military training from Mass Effect and Ruby's Huntsman skills from RWBY could create interesting battle strategies. Another aspect could be the technology transfer. Maybe the advanced tech in Mass Effect like biotics could be introduced to RWBY's world, causing a stir among the characters there. Also, the cultural differences between the two universes could lead to some great storylines. The more rigid military structure in Mass Effect compared to the more free - flowing world of RWBY could lead to clashes and reconciliations.
For example, the biotics in Mass Effect could be combined with the summons in Final Fantasy. A biotic user could enhance the power of a summoned creature like Ifrit. Or the tech abilities in Mass Effect could be used to upgrade the weapons in Final Fantasy. Garrus could help improve Cloud's Buster Sword with some advanced Mass Effect tech.
Well, it often blends the two universes by having characters from each interact. For example, a Mass Effect character might be introduced to the concept of the Force in the Star Wars universe. They could learn to use it in their own way. Or a Star Wars character could encounter the advanced technology of Mass Effect.
In Stargate, the technology is centered around the stargates which allow for instantaneous travel between planets. In Mass Effect, they have the Mass Relays for faster - than - light travel. In crossover fanfics, this difference often leads to interesting scenarios. For example, characters from Mass Effect might be amazed at the simplicity yet effectiveness of the stargate system. And in terms of races, the Goa'uld in Stargate are very different from the Krogan in Mass Effect. The Goa'uld are parasitic and power - hungry, while the Krogan are a tough, war - like race with a complex history.
One way to combine them creatively could be to have Naruto characters interact with the technology and species in the Mass Effect universe. For example, the Juubi's power could be a mystery that the Mass Effect characters are trying to understand or control. Maybe a character like Naruto could use his chakra powers in a way that is similar to biotics in Mass Effect.
The theme of the insignificance of humanity is also very prevalent. In many 'cthulhu mythos crossover fanfic', humans are often just pawns or are completely out of their depth when faced with the eldritch beings. Whether it's a crossover with a fantasy world or a modern - day detective story, the power and otherworldliness of the Cthulhu entities make humans seem small and helpless. In a crossover with a high - fantasy setting, the magic of that world may be no match for the chaos and power of the Cthulhu mythos. It shows how fragile human existence can be in the face of such cosmic horror.
