In many 'Master Chief RWBY' fanfics, they combine the universes by having Master Chief somehow end up in the RWBY world. This could be through a portal or some kind of interdimensional rift. Once he's there, his high - tech equipment and combat training from his own universe contrast with the more magical and combat - school - based RWBY world.
Character crossovers are a key way. Writers will bring characters from both universes into the same story. They might have Hermione meet Bella, and through their interactions, the two different worlds start to merge. The slash aspect can then be added by creating unique relationships between characters from the two series, like a budding romance between a wizard and a vampire. This not only combines the universes but also adds an interesting new dimension to the story.
Some writers create a situation where the problems in the Supernatural world are related to Hermione's world. Maybe a dark wizard has escaped into the Supernatural universe and is causing chaos. Hermione then has to team up with the Supernatural characters to stop this threat. This allows for a seamless combination of the two universes, as they both have to work towards a common goal using their respective skills and knowledge.
One way is through power systems. The biotics in Mass Effect and the chakra in Naruto can be related. Maybe a character in a fanfiction discovers that biotics are a form of chakra or vice versa. Also, the different races in Mass Effect and the clans in Naruto can interact in terms of politics and alliances. For instance, the Uchiha clan could form an alliance with the Salarians based on their shared intelligence and strategic thinking. And the stories can also use the different settings, like having a battle take place on a Mass Effect planet but with Naruto - style combat techniques.
Some fanfictions combine the two universes by having characters from both worlds meet in a neutral or new setting. For instance, a new island or city that is a melting pot of both Naruto - like ninjas and Black Lagoon - style mercenaries and criminals. Here, they interact, form alliances or rivalries, and the story unfolds with all the drama and action that comes from the clash of these two very different fictional cultures.
Yes, it is possible. In fanfiction, the boundaries between different universes can be blurred. For example, one could create a story where Harry Potter, as the Master of Death, somehow gets transported to the realm of Loki. Maybe Loki has a plan that involves Harry's power over death, or perhaps Harry is on a quest that leads him to cross paths with Loki. The magic systems in both universes could be intertwined in interesting ways. For instance, the magic in Harry Potter is more about spells and potions, while Loki has his own Asgardian magic. A good fanfiction could find a way to make these two types of magic interact, like Harry using his Patronus charm against one of Loki's illusions.
Well, they often blend the two universes by having the characters meet. For example, Ruby could run into Percy and they start to explore each other's worlds. They might also blend the powers. Maybe Weiss could use her Glyphs while Percy uses his water powers in a combined attack against a common enemy.
In many RWBY Space Marine fanfictions, they merge the two universes by having a portal or some sort of interdimensional rift. This allows the Space Marines to end up in the RWBY world. For example, in 'The Astartes of Remnant', a warp - like portal sucks in a group of Space Marines and drops them right into the middle of Vale.
Well, one way could be through a crossover spell or some sort of interdimensional rift. Maybe a character from Twilight somehow ends up in the Naruto world and has to adapt to the ninja way of life.
Often, it combines them through crossovers. For example, a portal could open between the Naruto universe and Shinji's world, allowing characters to travel between them.
Often through character crossovers. They put characters from both series in the same story. Like Harry and his friends could end up in Middle - earth, or the hobbits could find themselves at Hogwarts.
