Power and responsibility is also a common theme. As Midna has certain powers, she has to deal with the consequences of using them, like in 'Midna's Hidden Powers' where she discovers new powers and has to figure out how to use them responsibly.
Magic is a prevalent theme. Since Twilight is a powerful magic user, many fanfictions explore different aspects of her magic.

A lot of these fanfictions also explore the idea of transformation. Maybe Shad has the ability to turn Sonic or Amy into vampires, and this creates a whole new set of conflicts and relationships.
