The misadventures they have together are often the most interesting parts. For instance, when Dobby tries to protect Harry from something harmless, like a friendly house - elf from another family. Dobby gets all worked up and starts making a big scene with his wild gesturing and squeaky voice.
In some fanfictions, Dobby's attempts at imitating human behavior for Harry's sake can be highly entertaining. He might try to walk on two legs all the time like a human, but keeps tripping over his own feet. This shows his loyalty to Harry in a really cute and funny way.
Dobby sometimes helps Harry Potter in fanfiction by summoning other magical creatures to assist. For example, he could call upon friendly centaurs or house - elves from other families who are sympathetic to Harry's cause. This creates a sort of magical alliance around Harry, which is really cool. Dobby's social network among the magical beings is something that is often explored in interesting ways in fanfiction.
The most interesting aspect is the unique combination. Dobby is such an iconic and loveable character, and adding lemons into the mix creates a really strange yet fascinating concept. It can lead to all sorts of creative scenarios like Dobby using lemons in his magic, or having some sort of lemon - related quest.
The exploration of Dobby's relationship with Harry beyond what's in the books is really interesting. In fanfiction, we might see Dobby being more of a confidant to Harry, and their conversations can be really deep. Like in one story, Dobby gives Harry advice on how to deal with his feelings about Voldemort that no one else could give. This kind of emotional connection is a great plot addition.
A great Harry Dobby fanfiction could be set during the holidays. Dobby, who has a soft spot for Harry, tries to make Harry's Christmas at Hogwarts special. He decorates the Gryffindor common room with magical ornaments and cooks delicious magical treats for Harry and his friends.
One interesting Harry and Dobby fanfiction could be where Dobby uses his magic in creative ways to protect Harry from unexpected threats at Hogwarts. For example, he might create elaborate magical traps around Harry's dormitory to keep out dark wizards' spies.
One interesting Dobby - Harry fanfiction could be about Dobby helping Harry in a secret mission outside of Hogwarts. Dobby's unique magic and loyalty to Harry would make for an exciting adventure.
One interesting theme is Dobby's search for freedom and identity. Since he was a house - elf, his journey to become more than just a servant is a great theme. Another could be his friendship with Harry Potter and how it evolves over time.
In some fanfictions, Dobby might form an unlikely friendship with other Hogwarts students. He could teach them about house - elf magic, which is something not really covered in the original books. For instance, Dobby could show them how to use his brand of household magic for protection spells around the school during the dangerous times when Death Eaters are on the prowl.
A really funny one involves Dobby trying to cook for Harry at Hogwarts. He uses magic to mix up the ingredients in the most chaotic manner. He ends up creating a dish that looks like it has a life of its own and is bouncing around the kitchen.
The most interesting way Dobby helps Harry Potter in fan fiction might be his ability to manipulate the rules of the house - elf magic in creative ways. For example, he might find a loophole in the magic that binds him to his master's commands and use it to Harry's advantage. He could use his loyalty to Harry as a driving force to break free from the traditional limitations of a house - elf's magic and perform feats that are not only helpful but also quite unexpected and exciting for the story.
