How would the Hogwarts environment react if Harry Potter summons Echidna?

Hermione would be horrified. She's always by the book, and summoning Cthulhu is the most dangerous and unthinkable thing. She'd immediately start researching ways to send it back. Ron would be scared out of his wits but also a bit in awe of the power. Harry would be conflicted, realizing he's brought something extremely dangerous into their world.

One idea could be that Harry discovers an ancient spell in the restricted section of the library that has the power to summon Echidna. He summons her in a time of great need, like when Hogwarts is under a new dark threat. Echidna, being a mythical and powerful creature, could offer her unique knowledge or abilities to help Harry and his friends fight off the danger.

Flitwick might be quite intrigued. He loves magic in all its forms and fanfiction would show him new and different ways magic could be used in the Harry Potter world. He'd be interested in the creative spells and concepts that the fans come up with.

They would probably be shocked at first. I mean, Hogwarts reading fanfiction? It's a strange concept. But then they might be really curious about what Hogwarts is reading. They could try to get their hands on the same fanfiction to see what all the fuss is about.

The characters' reactions would be diverse. Snape would likely be very critical and use it as another reason to dislike Harry. He might see it as a sign of Harry's lack of respect for the wizarding world's traditions. The other students would be a mix of those who are fascinated by this strange Muggle object and those who are worried about its potential for harm. Hagrid would be confused, not really understanding what a gun is but knowing it doesn't seem right in Hogwarts. Overall, it would create a stir among the Hogwarts community and lead to a lot of discussions and speculations.

Harry might initially be shocked and confused. He's used to Hogwarts being his safe haven, so when it turns against him, he'll be at a loss. He may try to prove his innocence by finding evidence or confronting those who are spreading lies.

Hermione would probably be very shocked at first. She has always seen Snape as a rather cold and unapproachable figure. But after some thought, she might understand Harry's motives if he explained that it was about finding common ground and healing old wounds. Ron, on the other hand, would likely be more openly skeptical and might make some sarcastic comments at first, but eventually come around when he sees the positive impact it has on Harry.

Hermione would probably be a bit worried at first. She might think it's a waste of time compared to studying magic. But then she'd see the benefits of physical fitness and start to support him. Ron, on the other hand, would probably make fun of him a little but also be secretly impressed.

Well, Harry Potter is a rather humble character. He might initially feel a bit embarrassed to see himself as the center of so many fictional stories created by fans. If the fanfic portrays him as a hero in new adventures, he would probably be honored. However, if it misrepresents his friends or the values he holds dear, he could be a bit indignant. He would likely approach it with an open mind but also with a sense of protectiveness towards his own story and those he loves.

Maybe in a club setting. There could be a Harry Potter fanfiction club at Hogwarts where students meet regularly. They would bring in their favorite fanfictions, share them, and discuss how these new stories fit in with the original narrative. They might analyze the writing styles, the characterizations, and how the fan - created plots add to or deviate from the original. For example, if a fanfiction focuses on a minor character from the books and gives them a more prominent role, the club members could discuss the implications of that for the overall Potter universe.
