Autobot Matrix of Leadership

The Autobot Matrix of Leadership (sometimes the Creation Matrix or, rarely, the Autobot Matrix of Power or the Matrix of Light) is an artifact of great power, traditionally carried by the leader of the Autobots. By most accounts, it holds a part of the essence of Primus, the creator-god of the Transformers, although much about it, including its exact composition, remains a mystery. It generally appears as a hollow, spherical metal shell with two handles on either side and with a core sphere of blueish crystal at its center. The Matrix is the one thing, the only thing which Unicron fears.
