Authors usually portray Luna as the voice of reason. Since she has a very unique perspective on the wizarding world, she often acts as a counterbalance to Dark Harry. For example, when Harry is about to make a rash or cruel decision, Luna will step in and offer a different view. She is also shown as being very empathetic towards Harry, trying to understand the root of his darkness.
Luna is often written as the one who can break through Harry's dark shell. She's presented as having a very pure heart and a powerful intuition. In these stories, she uses her dreamy nature not as a weakness but as a strength. For instance, her dreams might hold clues to what Harry needs to do to return to the light. She is also shown as being very loyal to Harry, standing by him through all his trials and tribulations in the fanfiction world.
In many Dark Harry and Luna fanfictions, Luna is depicted as a sort of guide. Her knowledge of the strange and the unseen in the wizarding world gives her an edge. She might introduce Harry to magical creatures or ancient spells that can help him either control or overcome his dark side. And she's always portrayed as being unafraid of Harry's darkness, which makes her a very strong character in these stories.
In 'Harry Potter Dark Luna' fanfictions, often Luna's character is developed by giving her a troubled past. For example, she might have had some experiences with dark magic early on that shaped her in a different way. This could lead to her having a more cynical view of the wizarding world compared to her original, more whimsical self.
For Harry, his growth could be shown through how he becomes more open - minded. He starts to embrace Luna's quirks and her different way of seeing things, which in turn makes him more accepting in general. For example, he might initially be a bit hesitant about Luna's belief in some of the more out - there magical creatures, but as they date, he starts to see the beauty in her imagination.
Harry might become more at peace. After all the battles and losses, he could focus on the positive aspects of life. Luna, on the other hand, could become more confident in sharing her ideas. She no longer has to be in the shadow of the war and can be more outspoken.
In these fanfictions, they often interact with great respect for each other. Hermione, with her logical mind, might initially be a bit skeptical of Luna's more out - there ideas, but she soon comes to appreciate them. Luna, on the other hand, admires Hermione's intelligence and determination. They might exchange ideas about magic, with Luna sharing her more esoteric knowledge and Hermione providing the more textbook - based facts.
Harry's character could be consumed by anger and a thirst for revenge in a dark fanfiction. This would make him more aggressive and less empathetic. Luna, however, might use the situation to grow in strength. She could become a sort of moral compass for Harry, but at the same time, she might have to harden herself. Maybe she starts to study dark magic not to use it but to understand it better and find ways to counter it. This would change her from a carefree observer of the magical world to a more proactive defender.
Many fanfiction authors portray Harry's god - like powers in relation to his emotions. When he's angry, his powers might go out of control and cause chaos. But when he's calm and focused, he can perform amazing feats like healing all the sick and injured in the wizarding world in an instant. Also, his powers are sometimes shown to be connected to his bond with his friends. So, with Ron and Hermione by his side, his powers are amplified, and he can do things like open portals to other universes or create a shield around the whole of Hogwarts that nothing can penetrate.
One popular storyline is where Harry, in his 'dark' state, teams up with Luna to uncover a hidden conspiracy within the wizarding world. They might face off against a powerful dark force that has infiltrated Hogwarts or the Ministry. Another is a more angsty plot where Dark Harry has some internal conflict and Luna is the only one who can reach his true self. For example, she might use her unique understanding of the magical world to show him a different path.
In a dark setting, their relationship might become more complex. Harry, being dark, could initially push Luna away. But Luna, being Luna, would not give up easily. She might be the only one who still believes in the good in Harry. Their relationship could turn into a battle of wills, with Luna trying to break through Harry's dark shell and Harry trying to resist her influence.
I really like 'The Harry - Luna Connection'. In this fanfiction, the author focuses on how their unique bond grows over time. They start as friends who share a love for the strange and wonderful things in the wizarding world, and it gradually turns into a deep romantic relationship. There are some really cute scenes where Harry gives Luna a special charm he made himself, which has a little bit of his magic in it.
Harry is brave and a bit mischievous. His bravery allows him to take risks while playing pranks. For example, he might not be afraid to prank a strict teacher like Snape. Luna, on the other hand, is very creative and has an out - of - the - box thinking. So she could come up with really unique prank ideas, like making the school owls deliver love letters to the wrong people. Together, their personalities make their pranks both daring and imaginative.
