Some fanfictions may depict that Harry's children are transported to a parallel dimension where Voldemort never died. Here, they have to directly interact with Voldemort in his full power. They might try to use their own unique magic, inherited from Harry and their mother, to outwit Voldemort and find a way to return to their own dimension, all while avoiding being killed by Voldemort and his Death Eaters.
In some fanfiction, Voldemort and Snape interact in a very master - servant kind of way. Voldemort gives orders and Snape follows, but with a hidden agenda. For example, Snape might be subtly changing the Dark Lord's plans without him noticing.
Often in fanfiction, their relationship can change drastically. They could end up as allies, which would require both of them to change. Harry would have to see past Voldemort's evil deeds, and Voldemort would have to let go of his hatred for Harry. This exploration of character change makes fanfiction so interesting.
It could be that the pet is magically attracted to the glasses. Maybe the glasses have a certain charm or power that the pet senses, and it tries to steal them to bring back to Voldemort. For example, if the glasses can see through certain dark magic disguises, Voldemort would want to get his hands on them through his pet.
The pet could try to break Harry's glasses. Since Voldemort hates Harry, his pet might be programmed or trained to destroy things that are important to Harry. The glasses are a very visible and important part of Harry.
Voldemort's daughter herself would be in a very difficult position. She might be shunned by many in the wizarding world just because of who her father is. But some might be curious about her. For example, Luna Lovegood could be one of the first to approach her without judgment, which could start a chain reaction of other characters slowly warming up to her. And the Death Eaters might try to manipulate her into following in her father's footsteps.
Well, others could face it head - on. They might be proud of their mixed heritage, believing that they can be different from both their parents. They would use their unique background as a strength, showing the wizarding world that just because their father was Voldemort doesn't mean they are destined to be evil. They could actively work to change people's perceptions through their actions and magical abilities.
Harry often becomes more conflicted. He has always seen Voldemort as the ultimate evil, but now being mates, he has to re - evaluate his views. He might start to see the humanity in Voldemort, which makes him question his own beliefs and actions in the fight against the Dark Lord. For example, he may hesitate in battles more than before.
Hermione would be one of the main characters. She might be very skeptical at first about Harry's new friendship with Voldemort. She would constantly be on guard and try to figure out Voldemort's true intentions. Another would be Dumbledore. He would likely be watching the situation closely, trying to guide Harry and also be prepared to deal with Voldemort if he reverts to his evil ways.
Sometimes, fairies interact with humans by playing tricks on them, but these tricks are usually harmless. They may also befriend a human, especially a kind - hearted child. They can use their magic to make a human's life more interesting, like turning a dull day into a magical adventure. They might even teach humans about the secrets of nature and magic if they trust the human enough.
Harry's adventurous nature might draw Daphne out of her shell. Daphne's calm and composed self can help ground Harry when he's being too reckless.
