King Kong would be an obvious choice. The epic battles between Godzilla and King Kong are well - known, and a fanfiction could explore different scenarios of their encounters, like what if they had to team up against a greater threat.
There's a King of Fighters crossover fanfiction that involves characters from other SNK games like Samurai Shodown. It's quite exciting as it delves into the backstories of how these different universes could potentially interact. The story also adds new elements to the existing King of Fighters lore, which is really cool.
One popular 'king crossover fanfiction' could be a crossover between a king from a historical setting and a character from a fantasy world. For example, a crossover of King Arthur and a wizard from 'Harry Potter'. This kind of story can bring new and exciting plotlines as different worlds and characters collide.
Adaptation to new environments is also a theme. When the Monkey King is thrust into a new world in a crossover, he has to learn the rules and ways of that world. This can lead to humorous situations, like when he first encounters modern technology in a crossover set in the present day. He might mistake a smartphone for a magic device and try to use his powers on it.
I really liked a Nameless King crossover with the Dark Souls and Bloodborne universes. It's a complex story that delves deep into the similarities and differences between the two games' aesthetics and themes. The Nameless King's character is well - adapted to fit into this new, combined world, and the story is filled with mystery and horror elements that are characteristic of the Bloodborne side of things.
The Nameless King's mysterious nature makes crossover fanfiction unique. Since we don't know much about his backstory in the original, crossovers can fill in those gaps in creative ways. For example, in a crossover with the Lord of the Rings, his past could be linked to the ancient wars of Middle - earth.
One idea could be that Danny, as a half - ghost, has to prove himself to the Ghost King. Maybe there's a tournament in the Ghost Zone where Danny enters to show his worth. This could lead to some epic battles and alliances with other ghosts.
One common theme is the clash of different cultures. For example, when the Lion King world crosses with another, like 'Aladdin', there's a difference in the way the characters from each world view things like power, friendship, and family. Another theme is the idea of unity. Characters from different universes often have to come together to face a common threat.
Friendship or enmity can be a theme as well. When King Kong crosses paths with other characters, they can either form an unexpected bond, like a friendship with a human who understands his nature, or become bitter enemies due to their differences. This exploration of relationships adds depth to the crossover fanfiction stories.
One common theme is the clash of cultures. For example, when Arthur crosses over into a modern or alien world, his medieval values and the new - found values of the other world collide. Another theme is the test of leadership. No matter where he is, Arthur is often put in situations that test his leadership skills.
