Knuckles

Knuckles is an anthropomorphic echidna with predominantly red fur. He has three quills on each side of his head and one at the back, all covered in small barbs. He has standard-shaped eyes with black pupils and purple irises. Notably, when using chaos energy powers, the irises and barbs glow red. His muzzle is a standard flesh-colored, with a small, pointed black nose. White crescent-shaped fur can also be seen on his chest, and a medium-sized tail with a triple curl. Knuckles wears a pair of white boxing gloves with spikes attached to them. For footwear, he wears red hiking boots with a yellow stripe around the metatarsus, extending to the heels. The top of these boots is folded into green cuffs and metal plates on top, and the soles are ribbed gray.
