You know, the fat werewolf in paranormal romance often gets stuck in this weird middle ground. He's rarely the alpha, which I get, because those roles are usually about hyper-masculine, physically dominant ideals. But they make him the 'gentle giant' instead, which feels just as limiting. He's the pack's emotional core, the one who cooks the big meals and offers sage advice, while the ripped alpha broods and fights. It's like the genre swapped one stereotype for another.
I'd love to see a story where the fat shifter is the alpha, not despite his size but because of the different kind of strength and stability he represents. The 'Cinnamon Roll Alpha' trope is starting to peek through, but it's still niche. Mostly, his arc is about being loved 'as he is' by a mate, which is sweet but often frames his body as a hurdle to overcome for the romance, not an inherent part of his power. That narrative gets old.
