Which Sonic character has the highest IQ?

Ah, an intriguing question indeed! When it comes to the Sonic the Hedgehog universe, it's not often that we delve into the realm of IQ measurements for its colorful cast of characters. However, if we were to speculate based on their intelligence and problem-solving abilities, which Sonic character might boast the highest IQ? Could it be the genius scientist and inventor, Dr. Eggman (also known as Robotnik), who consistently devises elaborate schemes and machines to capture Sonic and his friends? Or perhaps it's Sonic himself, with his lightning-fast reflexes and cunning tactics that often allow him to outsmart his foes? On the other hand, there's Tails, the two-tailed fox who possesses a keen intellect and a passion for technology, often serving as a valuable ally to Sonic in his adventures. And let's not forget Knuckles, the red echidna with a strong sense of justice and a keen eye for detail, who might possess a form of street smarts that could rival even the sharpest minds. But ultimately, which Sonic character truly holds the title of highest IQ? That's a question that may never have a definitive answer, as it all depends on one's interpretation and perspective. So, what do you think? Who do you believe possesses the greatest intellect in the Sonic universe?
