The Leader Alien was the leader of The Great One's Worshipers. He was always calm and was the brains of the group. He had no weapons and appeared to be very lazy, as all he did was fly around on his Hover Disc. He also appeared with the Interpreter Alien and the Enforcer Alien. He can shoot laser beams from a tech device in his forehead.
The three aliens are similar to the three branches of government: the legislative that makes the law (Leader Alien), the judicial that interprets the law (Interpreter Alien), the executive that enforces the law (Enforcer Alien).
