The theme of adaptation is also present. Thanos has to adapt to the new rules, powers, and cultures of the crossover universe. At the same time, the characters in that universe have to adapt to his presence. For instance, if he crosses over into the Pokémon world, he would have to understand the power dynamics of Pokémon battles and how they are different from his usual battles with other powerful beings.
The theme of adaptation also frequently appears. Thanos has to adapt to the new rules and powers in the crossovers, and the native characters have to adapt to his presence. For instance, in a crossover with a magical universe, Thanos might have to figure out how to deal with magic, while the magical beings have to understand his technology - based power. This mutual adaptation forms a big part of many Thanos crossover fanfictions.
Power is a common theme. Thanos is extremely powerful and Loki is always seeking more power, so fanfics often explore how they interact in terms of power - whether it's a power struggle or a shared pursuit of power.
One common theme is the power dynamic. Since Thanos is so powerful, the fanfics often explore how the OC either challenges that power or is in awe of it. For example, in many stories, the OC might try to resist Thanos' tyrannical ways, creating a tense and interesting power struggle.
In Thanos Tony fanfiction, the theme of coexistence is sometimes present. Despite their differences, they might find a way to coexist in certain storylines. The exploration of their individual traumas is also a theme. Thanos has his own backstory that drives his actions, and Tony has his own set of traumas from his superhero journey. These traumas can shape their interactions in the fanfiction.
One common theme is power. Just like in the original Thanos story, female Thanos in fanfiction often seeks power, but sometimes for different reasons. For example, she might be seeking power to protect her people rather than to wipe out half of the universe. Another theme is redemption. Some fanfictions explore the idea of her trying to atone for her past actions or make up for the wrongs she has done.
One common theme is adventure. Since Technoblade is known for his Minecraft adventures, many crossovers put him in new and exciting places to explore. Another theme is friendship. For example, when he crosses over to other Minecraft communities, he often forms new friendships or rivalries with the characters there.
One common theme is the clash of different power systems. For example, when Berserk crosses with a series like 'Naruto', the magic and brute strength in Berserk contrast with the chakra - based powers in Naruto. Another theme is the exploration of different moral compasses. Characters from Berserk, which has a rather dark view of the world, interact with characters from more idealistic series, leading to interesting moral debates.
Power struggles are common. When Lucifer crosses over with other universes or characters, there's often a battle for dominance, like in crossovers with other powerful supernatural beings. Each character tries to assert their power and influence.
One common theme is culture shock. When characters from different worlds come to Earth, they experience new cultures, languages, and social norms. Another theme is power dynamics. If powerful characters from another realm arrive on Earth, it changes the balance of power. Also, the theme of adaptation is often present as the characters have to adapt to Earth's environment.
One common theme is power combination. For example, when RWBY characters cross over with characters from other universes like in 'RWBY x Avatar: The Last Airbender', they combine their powers. Ruby's speed could be enhanced with airbending techniques.
