Matrix of Leadership
The Matrix of Leadership is an artifact of great power that contains the essence of Primus and acts as a dimensional gateway to the Allspark, through which all living things are connected. It is traditionally carried by the current Autobot Leader.
Not much about the Matrix is common knowledge. Its exact nature remains largely a mystery. The Matrix is, however, widely known to possess "The Wisdom of the Ages." This may be due to its nature as a portal to the Allspark. As a Transformer lives and grows in experience, so does the Transformer's Spark, thus when it returns to the Allspark upon death, the lifetime's worth of knowledge is added to the whole.
It also includes the Creation Matrix, a computer program which can give a Transformer life.
The Matrix is the only thing which Unicron fears.
