Roberto Katze

His most prominent feature is his swept hair and accompanying his thick chin curtain beard. Unusual for a President, Roberto shows familiarity and openness to people nearly to the point of childishness. Although, his appearance says otherwise, he shows an intelligence uniquely his own.
