Luna could find a baby Nargle that she decides to raise. She has to figure out how to take care of it while also dealing with the disbelief and sometimes mockery from other students. But as the Nargle grows, it starts to show some amazing magical abilities that end up helping Hogwarts in a time of need.
A more complex plotline could be that there are two types of Nargles - good and bad. Luna discovers that the bad Nargles are being controlled by a dark force. She has to use her unique understanding of Nargles to try and separate the good from the bad. Harry and Hermione initially doubt her but as the situation worsens, they come to realize that Luna's knowledge is their only hope to save Hogwarts from the chaos that the bad Nargles are causing.

She tries to convince her friends in Gryffindor, including Harry, to help her protect the Nargles from some dark wizards who want to use their magic for evil.
One plotline could be Luna traveling back in time to meet the founders of Hogwarts. She could use her unique insights to help them with some early challenges they faced, like how to deal with magical creatures in the Forbidden Forest. This would be interesting as it shows Luna's wisdom applied to a very different time in Hogwarts' history.
There are many great fanfics out there. Some might focus on their adventures after the main events of the books, like exploring new magical creatures together.

One great fanfiction could be about Luna and Harry going on an adventure in the Forbidden Forest that wasn't in the original books.

Another could be a story where Luna helps Harry deal with the trauma of the final battle, showing her empathetic side in a more in - depth way.
One great Luna Lovegood fanfiction is 'Luna's Unseen Adventures'. It delves into Luna's experiences during the events that were only hinted at in the original books.

It's full of mystery and really captures Luna's unique character.
In a dark fanfiction, Voldemort could have placed a dark spell on Harry long before he knew. As Harry grows, the spell starts to take effect, making him darker.

Along the way, she discovers secrets about her own family's magic that could be the key to saving Harry and the wizarding world from the impending darkness.

In 'Harry Potter loves Luna Lovegood' fanfiction, a common characteristic is the way it can rewrite the established canon. It might change the way we view other relationships in the original series. Also, the fanfictions usually have a strong emotional core. Whether it's the way Harry discovers his feelings for Luna or how Luna opens up to Harry, emotions are at the forefront. There's also often a sense of mystery, as Luna always brings an air of mystery, and that gets carried over into their relationship in the fanfictions.
One common theme is the exploration of their unique friendship. Their personalities are so different yet complementary, and fanfictions often focus on how they understand and support each other. Another theme is the discovery of hidden magic. Luna has such a different view of magic, and when paired with Harry, they often go on quests to find new and strange magical elements. And of course, there's the theme of love in some fanfictions, whether it's a budding romantic love or a deep platonic love.
One possible plotline could be that it happens accidentally. Maybe a spell goes wrong during a joint mission they're on. And then they have to deal with the consequences in a world that is still recovering from the war. Another could be that it's part of a prophecy that they initially don't understand but as the story progresses, they realize the significance of their unborn child for the future of the wizarding world.
