A father in a Harry Potter fanfic could also be an educator. He could teach his children about the wizarding world, its history, and magic spells. He might pass on family - specific magical knowledge that has been passed down through generations.
Well, in Harry Potter fanfiction, the 'Dimension Father' might be a character with a very specific role. Maybe he's a sort of guardian of the dimensional boundaries. He ensures that no dark magic from other dimensions seeps into the main Harry Potter universe. He could also be a source of knowledge for characters like Hermione who are always eager to learn new magic. For instance, he might teach her about the spells and incantations that are unique to other dimensions, which she could then use to help Harry in his fight against the dark forces.
She could be a mentor figure. Just as Sherlock Holmes is known for his brilliant mind, Mummy Holmes could pass on some of that wisdom to the young wizards. For instance, she could teach them how to observe details more carefully, which is useful in both detective work and in dealing with the often - tricky magical situations at Hogwarts.
A 'creature baker' could be a source of unique magical treats. For example, they could make biscuits that give the eater the ability to communicate with certain magical creatures for a short time.
The Master of Death status might make Harry Potter a target in the Warcraft fanfic. There could be dark forces in the Warcraft world that want to either use his power for their own evil purposes or simply eliminate him because they fear his influence. This could lead to a lot of action - packed storylines, with Harry having to fight off these threats while also trying to uphold his values from the Harry Potter world.
He could be a purveyor of enchanted masks that give special abilities. For example, a mask that allows the wearer to speak Parseltongue even if they're not a Slytherin.
Perhaps Katrina Rinehart could be a seer. In the Harry Potter world, seers are very important as they can predict the future. If she were a seer, she could warn Harry and his friends about upcoming dangers, or she could be misinterpreted like Trelawney sometimes was. She would add an element of mystery and foresight to the story.
It could be a villain. Maybe it's been corrupted by dark magic and is out to attack students at Hogwarts.
A bartender in a Harry Potter fanfic can play a really interesting role. They could be the keeper of secrets in a wizarding pub, like the Leaky Cauldron. They might overhear all kinds of gossip and important information from the various witches and wizards who come in for a drink. They could also be a source of magical items or potions that are not easily available elsewhere, sold under the table perhaps.
In some Harry Potter fanfic, eggs could be used in potions. For example, they might be an ingredient for a magical elixir that gives the drinker a short - term boost of energy. Eggs could also be part of a magical creature's diet. Some fanfic might depict Hagrid using eggs to feed his various magical beasts like baby dragons or hippogriffs.
He could be a time - traveling character. Imagine Rhaegar from his own world ending up in the Harry Potter universe. He could be a key player in changing the course of certain events. For instance, if he has knowledge of a powerful dark magic that is starting to emerge in the Potter world, he might use his skills to counter it.
