Power exploration is also a big theme. Aang has his bending abilities, and when he enters a new world, how his powers compare and interact with the new powers there is often explored. For instance, in a crossover with a superhero universe, seeing how his bending stacks up against super strength or flight abilities makes for exciting reading.
One common theme is the clash of cultures. For example, when Aang is crossed over into a different fictional world, his Air Nomad culture and values often contrast with the new world's norms. This can lead to interesting storylines about acceptance and adaptation.
The theme of friendship is prevalent as well. Aang is a very social character, and in crossover fanfics, he often forms new friendships or has his existing friendships tested. In a crossover with the 'Harry Potter' universe, for example, his friendship with Katara might be compared to Harry's friendships at Hogwarts, and new bonds may form between him and the Hogwarts students.
