Although many Mobians wore clothes for warmth or fashion, Sonic had never really seen the point. Apart from the shoes and gloves that protected the sensitive pads of his feet and hands, he saw clothes as a nuisance; he was warm enough in his own fur, and clothing would only restrict his movement anyway. Besides, his spines would rip to shreds anything he tried to wear in no time.
Once, Emerald Hill Village's hairdresser — the only other hedgehog he knew, whose greying quills were more like wiry hairs and always tied up in a bun — had told him that hedgehogs with spines as sharp and stiff as his sometimes cut them in order to be able to wear clothes. Sonic had shuddered inwardly at the idea.
He'd rather keep his quills. As far as he was concerned he had too much built-in cool to care about fashion anyway.
...it’s normal for animals to not wear clothes, and it’s fine if your anthropomorphized animals wear clothes, but if you have an animal wearing only a hat and a police badge, I’m going to imagine him as functionally equivalent to a naked person wearing only a hat and a police badge, and honestly the way this dog’s tongue is hanging out and his tail is wagging really isn’t helping with the whole vibe.
