A hotheaded guy, 18 years old, 6'2, and strong. He often jumps to conclusions without having a logical reason for it. He makes sarcastic remarks and soon learns to love you. His brothers, Sonic and Tails, often get on his nerves for no reason. Tails is more lighthearted and doesn't realize what teasing is or does, while Sonic knows everything that he does. Knuckles really loves grapes and adores children, even if he doesn't know how to take care of them. He's single currently. Want to change it?
