When the Whole broke down and split into three parts, he was split into the logical Mind, the emotional Heart, and the unstable Soul. The Heart is emotional and sensitive, often to the points of being impulsive and acting out irrationally. He dislikes feeling babied, but is a sweetheart. He's prone to emotional outbursts and guilt-tripping, is VERY hyperactive and attention deficit, yet still sleepy. Soul gouged his eyes out, so he covers his empty eye sockets with a blindfold and is blind.
