Does Sonic have a weakness?

I'm curious, does Sonic, the iconic blue hedgehog from Sega's popular video game franchise, possess any discernible weaknesses? In the fast-paced world of his adventures, he's known for his incredible speed and agility, but is there anything that could slow him down or make him vulnerable? Is there a particular strategy or obstacle that his foes could exploit to gain an advantage? It's an intriguing question that begs for an answer, especially for those who have grown up with Sonic's adventures and continue to enjoy his high-octane escapades.
