In xenomorph and human lemon fanfiction, a common theme is the blurring of boundaries. This can be physical boundaries, like the xenomorph's ability to invade human bodies, which can be explored in a more metaphorical or psychological way in the fanfiction. Another theme is the concept of the 'other'. The xenomorph represents the ultimate 'other' to humans, and fanfiction may delve into how humans react to this extreme form of otherness. There's also often a theme of sacrifice. Humans might sacrifice themselves for the greater good when faced with the xenomorph threat, or in some cases, sacrifice their humanity in order to survive or understand the xenomorph better.
One common theme could be the exploration of the extreme contrast between the two species. The xenomorph is a terrifying, alien creature, while humans are more relatable. In fanfiction, this contrast might be used to create intense and unique relationships. Another theme could be survival in the face of the xenomorph's threat, with the human characters having to use their wits and any possible alliances, even with a xenomorph in some cases, to stay alive. Also, the idea of transformation or adaptation might be present, perhaps a human character taking on some traits of the xenomorph or vice versa in this fictional and often strange world of fanfiction.
Common themes in xenomorph and human lemon fanfiction often involve power dynamics. The xenomorph is typically a very powerful and dangerous being, so there can be stories where humans try to gain power over it, or the xenomorph exerts its power over the humans. There might also be themes related to forbidden love or attraction, which is a common trope in fanfiction in general. Since the two species are so different, the idea of an unusual attraction between a human and a xenomorph can make for an interesting and somewhat disturbing story. Additionally, themes of discovery and the unknown are prevalent, as the xenomorph is an enigma and the interactions between the two species can lead to new revelations about both.
