Z Fighters (Ｚ戦士, Zetto Senshi; also known as the Z Warriors or Earth's Special Forces, or even the Gold Fighters by Mr. Satan) are a small group of warriors located on Earth. Their duty is to defend Earth from major threats and to protect the seven mystical Dragon Balls from the hands of evil. Goku is the de facto leader of the group due to his incredible success rates against villains in Dragon Ball, victory over the Saiyans, and his victory over Frieza. Over time, the group consistently bolstered its ranks through the addition of former enemies and new heroes and routinely overcame seemingly insurmountable opponents, always emerging victorious against progressively more powerful foes.
