Can you give examples of how Harry Potter is related to Norse goddess in fanfiction?

There could be. Fanfiction is all about creativity. Maybe the author has a particular interest in Norse mythology and wants to incorporate it into the Harry Potter world. For example, a Norse goddess could be a hidden force guiding Harry's journey, or a powerful entity that he has to face. It's a way to expand the existing Harry Potter universe with different cultural and mythological elements.

I'm not sure of specific titles off - hand. But generally, it could be a story that just focuses on the daily life at Hogwarts without getting into big battles between good and evil. Maybe it's about a student's normal school year, dealing with classes, friendships, and minor rivalries.

There are fanfictions where Harry Potter outsmarts a powerful dark wizard by pretending to be on their side. He infiltrates the wizard's lair and gradually gains their trust. While doing so, he learns about the wizard's plans and weaknesses. Then, at the crucial moment, he uses this knowledge to turn the tables. He might also use polyjuice potion to create distractions or mislead the wizard and his followers, showing his clever use of magic items and potions to outsmart his adversary.

One example could be fanfictions that rewrite the relationship between Harry and Hermione as a romantic one in a very extreme way that goes against the platonic relationship in the original books. Some fans who are purists might contest this as it changes the fundamental dynamic of the trio.

One way is through character creation. For example, a new character could be based on a Norse god or goddess, with their powers and personalities reflected in the Harry Potter world. So, like a character inspired by Thor could have the power of lightning in the magical context of Hogwarts.

One example is when a character uses an enemy's name in a binding spell. If the name has power, the spell will be more effective. Another is when a character discovers their true family name which unlocks a hidden magical ability. For instance, a fanfic might have a character find out they are related to a powerful wizarding family and suddenly they can access a special kind of magic that was tied to that family name.

I'm sorry, without having read specific Harry Potter fanfictions that use 'hiraishin', it's difficult to give exact examples. But it could be used as a way for a character to quickly escape from a dangerous situation, like a Death Eater attack.

One example could be a fanfiction where Harry uses his invisibility cloak in a more devious way to play pranks on the Slytherins, rather than just for sneaking around. Another might be if Ron uses his chess skills not just for playing the game but to outwit his enemies in a more strategic and underhanded way.

Without having read the fanfictions that use Clause 13, it's a bit of a shot in the dark. But let's say Clause 13 is related to the use of magic in Muggle - populated areas. In one fanfiction, a young wizard might accidentally use magic in a Muggle town, violating Clause 13. This could lead to a Ministry of Magic investigation, with the wizard having to prove it was an accident or face punishment. Or if Clause 13 is about the sharing of certain spells among students, a character might be tempted to share a powerful spell in secret, which is against Clause 13, and this could create a web of secrecy and potential betrayal within the Hogwarts community.

One fragile element could be a new magical creature introduced in the fanfiction. If the rules governing this creature are not well - defined, it can make the story seem inconsistent and fragile. For example, if the creature has powers that are too overpowered or not properly explained, it can disrupt the balance of the Harry Potter universe within the fanfiction.
