In many fanfictions, the two universes merge through magical portals. For example, in some stories, a powerful spell in the Winx Club world accidentally creates a portal to the Pokemon world, allowing the characters to cross over.
Another way is that some sort of powerful artifact or energy source attracts the characters from one universe to the other. For instance, a rare Pokemon with special powers might draw the Winx girls into the Pokemon world. This creates a situation where they have to interact and co - exist, leading to a merge of sorts between the two universes.
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.
In many fanfictions, they merge the universes through magical portals. For example, a spell in the 'Harry Potter' world might accidentally open a portal to the 'Btvs' universe where Angel exists. This allows characters from both to interact.
Typically, it combines the two universes by having characters interact. Naruto characters might find themselves in the magical world of Winx Club or vice versa. They would then have to adapt to the new environment and rules. But as for the 'lemon' part which might not be suitable, we should focus on the positive aspects of this combination like how Naruto's combat skills can be compared and contrasted with the Winx Club's magical battles.
One way they can merge is through character crossovers. For example, a character from Game of Thrones like Jon Snow could be transported into the Warhammer universe. He might find himself in the middle of a battle between different factions in Warhammer, using his skills learned in Westeros to survive. His sense of honor and leadership could also have an impact on the Warhammer characters he encounters.
These fanfictions may somewhat change the perception of the characters. In the original, they are seen as young, carefree fairies. But in pregnancy fanfictions, they become more mature and responsible. It might also introduce new relationships and dynamics. For instance, how the male characters in the Winx Club universe react to the news of pregnancy can be a whole new aspect that wasn't really explored in the original concept.
They often blend the two universes by having characters from Kingdom Hearts enter the Pokemon world or vice versa. For example, a character like Sora might find himself in a Pokemon region and start interacting with trainers and Pokemon. This creates a lot of interesting scenarios as the powers and abilities from Kingdom Hearts are different from those in the Pokemon world.
In some fanfictions, the merge happens when a powerful artifact from either universe is activated. This could be a Kamen Rider's belt or a powerful relic from Highschool DxD. When this happens, it creates a rift that pulls elements from one universe into the other. The characters then have to deal with the new and unexpected situations. For instance, the devils in DxD might be intrigued by the Kamen Rider technology and try to harness it for their own purposes.
Fanfictions about Bloom and Sky's kiss contribute to the Winx Club fandom in multiple ways. For one, they keep the interest in the characters alive even between seasons or when there's a lull in official content. They also allow fans to connect with each other. Fans who write and read these fanfictions can discuss their ideas, interpretations, and what they would like to see happen in the relationship. Moreover, it can inspire fan art, further enriching the fandom. Artists may be inspired by the romantic scenes described in the fanfictions to create beautiful illustrations of Bloom and Sky.
Well, in many fanfics, they merge the universes by having some sort of magical or scientific accident. For example, in one fanfic, a portal opened up between Camp Half - Blood and the Young Justice headquarters. The female Percy Jackson then gets sucked into the Young Justice world and has to adapt.
In many fanfictions, magic is the key to merging the two universes. Fem Harry Potter's world of magic can act as a bridge. For example, a powerful spell might accidentally open a portal between the wizarding world and Metropolis, allowing the two to interact.
