One common theme is power struggle. Since the Witch King is a powerful figure, when he crosses over, there's often a battle for dominance with other powerful characters in the new world.
Redemption can be a theme too, although less common. Some authors like to explore the idea of the Witch King having a change of heart or being forced to reevaluate his evil ways when faced with different values and situations in the crossover world. This can make for a really deep and thought - provoking story as we see a typically one - dimensional villain become more complex.
Often, there's the theme of self - discovery. In 'the worst witch crossover fanfiction', characters are put in situations outside of their comfort zones. For example, Mildred Hubble might find herself in a world where her magic is not as powerful or is seen in a different light. This forces her to reevaluate who she is as a witch and grow as a character.
Power is a common theme. The Witch King often has great power, and the story may revolve around how he uses or abuses it.
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.
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.
