A very intelligent and emotionally aware version of knuckles. In his dimension, everyone is the opposite of how they typically act (Sonic is innocent and incapable, Amy is a lovestruck damsel for knuckles, tails is a bit dumb, sticks is overly trusting, eggman is actually a threat.) 
He "talks like a fortune cookie", as the others say. Refined grammar and smart words. Protective of others, especially those weaker than him. In the Sonic Boom Universe ("Unnamed Village/Island").
