Though various incarnations sometimes change details, in most versions the Green Hornet is the alter ego of Britt Reid, wealthy young publisher of the Daily Sentinel newspaper by day, who goes out in his masked "Green Hornet" identity at night to fight crime as a vigilante. Reid is accompanied by his loyal and similarly masked partner and confidant, Kato, who drives their technologically advanced car, the "Black Beauty". As the Green Hornet, Reid masquerades as a criminal to infiltrate the underworld, leaving behind criminals and any incriminating evidence found for the police.
