Love and protection are common themes. Arthur's possessiveness often comes from his love for Merlin and his desire to protect him from harm. For example, in many fanfics, Arthur will not allow others to harm or even insult Merlin.
Jealousy can also be a theme. Arthur may get jealous when others show too much interest in Merlin. This jealousy then fuels his possessive actions. For instance, if another knight is getting too friendly with Merlin, Arthur will step in and assert his claim on Merlin.
The theme of loyalty is intertwined. Merlin is loyal to Arthur, and Arthur's possessiveness can be seen as a way of reciprocating that loyalty. It's like he's saying 'You're mine because you've been so loyal to me'. This creates a complex dynamic between them in the fanfiction stories.
Love, in different forms, is also a theme. It could be platonic love with a possessive edge, or it could be budding romantic love. The fanfiction may explore how this love affects their actions and decisions. For example, Arthur's possessive actions might be his way of expressing love without fully realizing it. And Merlin's reaction to it can be a way to show the growth of their relationship.
One common theme is friendship. Their relationship is often at the heart of the stories, showing how they support and grow with each other. Another is loyalty. Arthur and Merlin are extremely loyal to each other in the original series, and this is often emphasized in fanfiction.
