Knuckles is a powerful character and one of the most beloved in the Sonic franchise. He is a fiercely loyal and protective echidna who has spent his entire life on Angel Island, the Floating Island that houses the Master Emerald, which powers the planet Mobius. Knuckles is known for his strength and resolute determination to protect his home and the Master Emerald, and to thwart Dr. Robotnik’s plans for the world.
What animal is knuckles?
The Sega team who designed Knuckles looked at many different animals as inspiration for the character. They settled on using a hedgehog, an armadillo, a fox, and an echidna as the basis for his physical characteristics. The echidna is an intriguing species of egg-laying mammals native to Australia and New Guinea. They look like a porcupine with the body and spikes of a hedgehog, the snout, tongue, and dietary habit of an anteater, and the ability to lay eggs just like a platypus (which is also an egg-laying mammal).
Despite his red skin and anthropomorphic features, Knuckles retains certain echidna traits that help distinguish him from other characters in the Sonic franchise. For example, his heightened strength and knack for digging are based on the natural abilities of real echidnas. This has helped make him a memorable and iconic gaming character. He is a beloved part of the Sonic family, along with his friends Ray, Vector, Charmy Bee, and the rest of the Chaotix.
