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.
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.
In Thanos Tony fanfiction, the theme of coexistence is sometimes present. Despite their differences, they might find a way to coexist in certain storylines.

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.

Since Thanos is a well - known villain, Tony has to decide whether to follow in his father's footsteps or be a hero. And power is also a theme, as he may inherit some of Thanos' power.
A common theme is the clash of ideologies. Thanos with his view of 'balancing the universe' and Tony, the defender of Earth. Their different beliefs often lead to intense confrontations and debates within the fanfictions.
Redemption can also be a theme. Maybe the OC tries to bring out a different side of Thanos, a more humane or less tyrannical side. This often involves a complex relationship development between the two characters in the fanfiction.
Power is a common theme. Both Thanos and Loki are power - hungry in their own ways. In fanfictions, they often either compete for power or try to use each other's power for their own goals. Another theme is redemption. Sometimes Loki is seen as a way for Thanos to find redemption, or vice versa.
