Another theme is the exploration of their powers and how they can support each other in a relationship. Xander doesn't have supernatural powers like Willow at first, but fanfictions might play with the idea of how he could still be an important part of her life and vice versa in a romantic context. For example, he could be the emotional support she needs while she uses her magic to protect them. It often shows how two different characters can complement each other in a relationship.
One common theme is friendship turned into love. Since they start as friends in the original series, many fanfictions explore how that friendship could evolve into a romantic relationship over time.
Some fanfictions also have the theme of redemption. Maybe Xander has made mistakes or Willow has had some dark moments with her magic. Their relationship in these fanfictions can be a way for them to redeem themselves or grow as characters. It's like they find strength in each other to become better versions of themselves while being in a relationship.
One common theme could be character development. Writers might explore Xander's growth in different scenarios. Another could be relationships, like his friendships or romantic interests.
Common themes in 'xander is not human fanfiction' include acceptance. Xander has to deal with whether or not others will accept his non - human identity. Another theme is the struggle against his own non - human instincts. If he's part - demon or something similar, he may have to fight against urges that come with that nature. Additionally, the theme of purpose often arises. Xander may wonder what his purpose is now that he's not human, and the fic may explore his journey to find that purpose.
Power - up is a very common theme. Xander goes from being the 'normal' one in the group to having some extraordinary powers or skills. Also, friendship is often explored. His relationships with Buffy, Willow, and the others are either strengthened or tested as he becomes a bamf. In some stories, his newfound status makes his friends see him in a whole new light, which can be both positive and negative for their friendships.
One common theme is the exploration of their unlikely connection. Since they are so different in the original context, fanfiction often focuses on how they bridge that gap.
Another common theme is the clash of different mythologies. The show Xander is from might have its own set of supernatural rules and creatures, and when combined with the Supernatural world, there are a lot of interesting interactions. This can lead to stories where the characters have to figure out how to deal with new and unexpected threats that come from the combination of these two different mythologies.
Since I don't promote or encourage lemon (explicit) content, I can't really say about the common themes in such fanfiction. But in general, in normal Xander and Buffy fanfiction, common themes include their friendship, their shared experiences in fighting vampires and other supernatural beings, and the growth of their relationship over time.
One more theme is the anticipation. Writers like to build up the anticipation of the kiss. They show all the little glances, accidental touches, and conversations that lead up to that one moment of the kiss. And also, the after - effects of the kiss, like how they deal with the newfound closeness and what it means for their future interactions.
Well, if we're talking about non - explicit interpretations of 'lemon' themes, it could be about Xander's romantic relationships. Maybe exploring his unrequited love or his first love experiences. Another theme could be his growth as a person within those relationships, learning about himself and others.
Another theme is the battle between good and evil. Angel is a vampire fighting for good, and Xander is often involved in the fight against the forces of darkness in Sunnydale. Fanfictions may show how they combine their strengths, Xander's street - smart knowledge and Angel's supernatural abilities, to combat evil.
