Man, this question takes me back to my deep-dive into the 'Harry Potter' lore! Bill Weasley isn't a werewolf, but he does get seriously scarred by Fenrir Greyback during the Battle of the Astronomy Tower in 'Harry Potter and the Half-Blood Prince'. The attack leaves him with some wolfish traits—like a fondness for rare steak—but he doesn't transform under the full moon. It's more like a partial curse, which adds such a cool layer to his character. J.K. Rowling really nails the idea of lingering magic wounds, and Bill's scars become this subtle symbol of resilience. Plus, it's wild how Fleur loves him even more for it—gotta respect that!
I always thought Bill's storyline was underrated. He's this cool, curse-breaking older brother who bridges the gap between the Weasley kids' chaos and the adult wizarding world. His relationship with Fleur also shakes up the family dynamic in the best way. The werewolf question pops up a lot because Greyback's such a terrifying villain, but Bill's fate is way more nuanced. It's not black-and-white, just like real life—magical or not.
No, Bill Weasley isn't a werewolf. He got severely injured by a werewolf, Fenrir Greyback, in the 'Harry Potter and the Half-Blood Prince', that's true. But it's crucial to remember that Greyback wasn't in his wolf form at that time. So Bill did not turn into a werewolf, though he did carry some scars and traits due to the attack.
