LEADER-1 was once the ruler of a group of cyborgs fighting an endless civil war. When his very universe was threatened by a spacetime anomaly, LEADER-1 abandoned his people and escaped to another universe. There, he found another world plunged into war, and he liked what he saw. Allying himself with Optimus Prime, LEADER-1 has put his considerable skill at command and destruction to successful use for the Autobots.
