Who could be good characters to include in Harry Potter foster family fanfiction?

Hermione Granger would also be a great addition. She could use her extensive knowledge from the library to help solve problems in the Herbology plot. Maybe she discovers a hidden section in the library about a lost herbology technique and tries to bring it back to the modern - day Hogwarts Herbology class.

Hermione could be a great character to include. Since she's Harry's friend, she might follow him in his runaway adventure. In a crossover with the Marvel universe, Iron Man could be interesting. His high - tech gadgets and quick thinking would contrast with Harry's magic. Also, Aragorn from The Lord of the Rings could be included. His leadership skills and combat abilities would be useful in any dangerous situations they encounter.

Hermione Granger could be involved. She's smart and might take an interest in how the Muggle government operates. She could help the Prime Minister understand the wizarding world better. Another character could be Arthur Weasley. His fascination with Muggle objects would make for some humorous interactions with the Prime Minister and also help bridge the gap between the two worlds.

Harry Potter and Jane Foster themselves are great to pair. Their different backgrounds, one in magic and the other in science, can create a lot of interesting interactions. Hermione could also be paired with Jane Foster. Hermione's thirst for knowledge and love of learning could mesh well with Jane's scientific mind. They could exchange ideas about different forms of knowledge. Another good pair could be Thor (since he's related to Jane Foster) and Hagrid. They both have a big - hearted and strong - willed nature and could have some fun adventures together in a fanfic.

Dumbledore could be a central figure in the fanfiction related to the original family. He has always been full of secrets and knowledge. He might have known about the original family all along and could be guiding Harry or other characters to discover the family's significance for a greater purpose, like the final defeat of Voldemort or the preservation of some ancient magic.

Obviously, Harry Potter himself would be a main character. And then perhaps Prince William or Prince Harry could be important characters too. They could be the ones who bridge the gap between the Royal Family and the wizarding world. Hermione and Ron might also be involved, helping Harry to deal with the unique situation of the Royal Family in the wizarding world.

Obviously, the Weasley twins themselves are essential. But also including Hermione would be great. She could be the voice of reason when the twins get too carried away with their pranks in the crossover world. Her intelligence and knowledge of magic could help them out of many tricky situations.

Dumbledore could be included. Even though Harry is on his own, Dumbledore's wisdom could still be a guiding force, perhaps through memories or some magical means. Also, Hagrid. His knowledge of the magical creatures could come in handy for Harry in his solo adventures. Another character could be Luna. Her unique perspective might inspire Harry when he's facing difficulties alone.

A young wizard from a far - off land who has a completely different style of magic. He could bring new spells and techniques to the Triwizard Cup tasks. Another could be an old retired champion who comes back to mentor the current champions. And a magical creature that has the ability to communicate with the champions and give them hints about the tasks related to the Triwizard Cup.

Hermione could be really interesting in a crossover. Her intelligence and magic skills would be useful in any new world she's thrust into. Maybe in a crossover with 'Doctor Who', she could figure out the time - traveling aspects faster than Harry.
