Knuckles is a stubborn, short-tempered echidna. He's skilled in martial arts and could tear a rock apart with his bare hands, he's trained all his life and devoted his life to protecting the Master Emerald. Despite his devotion, Knuckles is naive and easily baffled if the words are chosen right, he has little knowledge of human things, having trained all his life, all Knuckles knows is the battle field. Knuckles has red and white fur, violet eyes and white gloves with pointy, spiky knuckles.
