It shows how pregnancy and birth are a normal part of the Pokemon world's cycle of life, and how all the elements in the environment, from other Pokemon to the terrain, play a role in this process.
The theme of discovery is also prevalent. The OC often discovers the existence and significance of Castiel's wings, which can be a journey of self - discovery for both characters. It might also lead to the discovery of new aspects of the Supernatural world they inhabit, like hidden places or powers that are related to the wings.
One of the main themes is acceptance. In these fanfictions, hybrids usually face discrimination from regular Pokemon or humans. So, the journey towards being accepted is a big part of the story.
