In the official universes of X - Men (where Jean Grey is from) and Harry Potter, there's no such connection. However, in the world of fanfiction, it's possible. Fanfiction writers often create crossovers with the most unexpected pairings. But I'm not sure if there's a specific well - known fanfic with this exact premise.
It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
It would be really strange yet interesting. Jean Grey's powers could have a huge impact on Harry's upbringing. Maybe he'd inherit some of her telepathic abilities in a very different magical world. And the X - Men and Hogwarts elements would be mashed up in a unique way.
My friend's mom has a pair of mom jeans that are so high - waisted. One time, we were at the mall and a little kid pointed at her and asked his mom if she was wearing a 'belt - up - to - her - chest' pants. It was hilarious.
The ending of the AOT manga was quite controversial among fans. Some were satisfied, while others felt it was rushed or left many questions unanswered.
There could be various fanfictions. Maybe some that focus on alternative endings, like ones where certain characters survive who didn't in the original. For example, a fanfiction where Erwin survives and leads the Scouts in a different way.
A lady was wearing mom jeans and tried to do some yoga in them. The tightness around the hips and the looseness at the ankles made her look like a pretzel gone wrong. Everyone in the class couldn't stop giggling.
It could mean that a person who is a fan of 'Attack on Titan' (AOT) is reading or watching fan - created fictional works related to AOT. Maybe they are interested in seeing different interpretations or storylines that fans have come up with.
