One of the main themes is the exploration of power. Loki is a powerful being, and in the context of the Harry Potter universe, his power is compared and contrasted with the power of wizards like Harry. There's also the theme of deception. Loki is known for his trickery, and in the fanfics, this often plays out in his interactions with the characters from Harry Potter. For example, he might deceive Snape into thinking he's a new teacher or something similar. And of course, there's the theme of adventure, as the two different universes coming together often lead to exciting and unexpected adventures.
Well, the concept of identity is quite common. Loki has his own complex identity, and when he enters the Harry Potter world, he has to re - evaluate it, and sometimes the characters in Harry Potter question their own identities in relation to him. Another theme is friendship or lack thereof. Since Loki has a rather complicated relationship with the concept of friendship, it's interesting to see how he interacts with Harry and his friends. Some fanfics also explore the theme of redemption, as Loki might try to atone for his past misdeeds in the new world of Harry Potter.
