johannvanguard: My idea would be that Spider-Man could help Tony Stark with a project involving dimensional travel. Then something goes wrong with the machine and Spider-Man tries to stop it, only to be sucked into the portal. Spider-Man then finds himself at Canterlot High School in Canterlot.
Answer: I've actually been thinking of an idea similar to that, but I also wanted to place Doc Ock in it as a bad guy for Spidey and the Rainbooms to fight as the Dazzlings. I've been thinking of basing some things of the MCU and hinting the Infinity Stones in my story.
Another idea I have is that the Avengers send Peter to Equestria because a threat is coming and they don't think it's too much a big deal so they send Spidey due to him being a kid. This will cause Peter to fell betrayed and make him more cynical making him believe that no one threats him seriously, as a mean to prove himself Peter will want to go all lone wolf and deal with the problem by himself. This will also cause tension with the mane 6 and others, making them skeptical about him.
