The theme of adaptation is quite common. The OC has to adapt to the elven society if they end up in Lothlórien, and Haldir has to adapt to having this new, unknown person in his world. There can also be the theme of heroism. They might face a threat together, like a group of orcs invading a peaceful area. Through their combined efforts, they become heroes in their own right, and this can strengthen their bond and also be a central part of the fanfiction's plot.
One possible scenario in Haldir and OC fanfiction could be that the OC is a traveler from a far - off land who stumbles upon Haldir in Lothlórien. Haldir, being a watchful elf, is initially cautious but as they interact more, they start to understand each other's worlds. Maybe the OC has some unique skills or knowledge that intrigues Haldir, like knowledge of a different form of magic or a different culture's way of fighting. This could lead to a friendship or even a deeper relationship as they face challenges together in Middle - earth.

This creates interesting storylines as they have to overcome their cultural differences. And of course, power struggles within the orc tribes are also a common theme, as different orcs vie for leadership and influence.
