Well, characters could interact with runes in a more practical way too. They might inscribe runes on their clothing for protection. A character could draw a rune on their cloak that makes them invisible to certain dark creatures. Or they might use runes to mark paths in the Forbidden Forest so they don't get lost. Runes could also be used in duels, where a wizard casts a spell enhanced by a rune they hold in their hand or have inscribed on their wand.
Some characters might study runes intensively in the 'Harry Potter Rune Fanfic'. They could spend hours in the library poring over ancient tomes about runic magic. For example, Hermione would probably be really into it, taking detailed notes and trying to figure out how to apply rune knowledge to solve problems or defeat enemies.
Some characters might be lured into the 'dark land' out of curiosity. They may think they can find power or knowledge there. Others might be forced to enter it against their will, perhaps by dark wizards who want to use them for some dark purpose. Once inside, they could either be overcome by the dark forces or find a way to resist and fight back.
In Harry Potter fanfic, goblins' interactions can be complex. When it comes to Death Eaters, goblins usually keep their distance as they don't want to get involved in the dark wizard's affairs. But if a Death Eater tries to steal from Gringotts, the goblins will fight back fiercely. On the other hand, with characters like Harry Potter himself, goblins might be initially suspicious but can come to respect him if he shows respect for their ways and culture.
In some fanfics, students might start their own magical creature rescue groups. They could rescue injured or abandoned creatures like Bowtruckles. They would then nurse them back to health in a secret location. This not only shows their love for magical creatures but also their determination to protect them, which is a new aspect not fully explored in the original books.
In many Harry Potter fanfic, brother wands interact in a way that is related to their cores. If the cores are from the same magical creature, like both having a phoenix feather core, they could have a stronger connection. This connection might allow the wizards to communicate telepathically through their wands, or it could enhance their spell - casting abilities when they are together. It's a creative way for fanfic authors to expand on the magical world of Harry Potter.
The Stargate characters are used to dealing with advanced technology and alien cultures. When they meet the Harry Potter characters, they might be initially confused by magic. For example, Jack O'Neill might be both amused and intrigued by the spells the wizards cast. Meanwhile, Harry Potter and his friends would be curious about the Stargate technology and the different worlds it can access.
The characters would interact in very strange ways. The Hogwarts students would be shocked by the Jackass crew's behavior. The Gryffindors might be initially intrigued, while the Slytherins would be disdainful. Harry and his friends would probably try to keep the Jackass guys out of trouble, but it would be difficult as they are always looking for the next wild thing to do.
Harry might be in awe of Elsa's powers at first. He would likely approach her with caution and respect, as he does with most powerful beings. Elsa, on the other hand, would be curious about Harry's world of wands and spells. They could start by sharing their stories. Harry would talk about Voldemort and his battles, and Elsa would share her experiences with her frozen kingdom and her isolation.
The Avengers could be impressed by the magic of the Harry Potter characters. For instance, Captain America might be in awe of the Patronus charm. And the Harry Potter characters could be amazed by the Avengers' superpowers. Hermione might be very interested in Bruce Banner's scientific knowledge.
Well, Ron might be initially terrified of Slenderman. But when his friends are in danger, he would step up. The Weasley twins could try to play pranks on Slenderman, not fully realizing the danger at first. Dumbledore, on the other hand, would be very cautious. He might observe Slenderman from a distance, trying to understand his nature before taking any action. In a 'Harry Potter and Slenderman fanfic', these interactions would create a lot of interesting scenarios.
They might interact as allies. For instance, Itachi's combat skills and strategic mind could help Harry in battles against Voldemort's forces. Harry, in turn, could introduce Itachi to the magic of the wizarding world, like spells that could enhance Itachi's abilities further.
