One common theme is adventure. The female oc often embarks on some sort of journey, and Legolas is either part of it from the start or joins later. For example, they might be on a quest to find a lost artifact or to save a particular region in Middle - earth.
Love and attraction are also very common. The relationship between Legolas and the female oc can range from a slow - burning friendship that turns into love to an instant attraction. In many of these stories, they have to overcome obstacles like differences in their cultures or backgrounds to be together.
One common theme is adventure. The OC often goes on quests or adventures with Legolas. Another is friendship, as they develop a bond that might be different from the ones Legolas has with his known companions. And love can also be a theme, whether it's a budding romantic relationship or a deep platonic love.
One common theme is the 'forbidden love' aspect. Since Legolas is an elf from a different world or culture in the Tolkien universe, the relationship with an OC (original character) often faces various obstacles. Another theme is the adventure - love combination. The couple might go on quests together, and their love develops during these adventures.
One common theme is the discovery of the soulmate bond. Usually, the OC and Legolas start off not knowing they are soulmates and then gradually realize it through various events.
One common theme is love. The love between Legolas and the OC is central, and it extends to their love for their baby. It shows how their relationship grows stronger with the addition of the new family member.
Love and romance also feature often. It could be a love story between female Legolas and an original character created by the author. Or it could be a reimagined version of a relationship that was hinted at in the original works. Her elven grace and beauty make her an interesting character for love - related plotlines in these fanfictions.
Adventure is also a big theme. They often go on quests together, like exploring uncharted parts of Middle - earth or fighting against dark forces. This not only tests their physical strength but also deepens their bond as they face difficulties side by side.
One common theme is the clash of two different worlds. Since Harry is from the wizarding world and Legolas is from Middle - earth, there's often a lot of exploration of how their different cultures and magic systems interact. Another theme is the power of love that can bridge the gap between two very different individuals.
One common theme is the reaction of the other characters. They might be shocked, supportive or confused. Another theme could be the physical and emotional changes Legolas goes through.
Friendship is also a big theme. Despite their age and status differences, they form a deep bond. For example, in many fanfictions, they share secrets and support each other through difficult times. Another theme could be the passing on of knowledge. Elrond, being very old and wise, imparts his knowledge about Middle - earth, its history, and magic to Legolas.
Adventure is also a common theme. Given that both characters are from action - packed universes, many fanfictions will have them embark on quests or battles together. This could involve fighting against dark forces from either the Harry Potter or Lord of the Rings universes, or even new threats created specifically for the fanfiction.
