The premise of your question, "who is the leader of the zodiac," suggests a misunderstanding. The Zodiac is not an organization, but rather a belt of 12 constellations that line up along Earth's ecliptic (the apparent path of the Sun across the sky). Each of the 12 signs of the Zodiac corresponds to a particular period of the year and is associated with certain celestial bodies, historical figures, or myths in various cultures. Therefore, there is no 'leader' of the Zodiac.
