Optimus Prime contains the Creation Matrix within his chest. The matrix is the infinite storage receptacle of Wisdom and knowledge. When the Matrix is opened, during the darkest hour, the power is released and all sinister forces are banished. The Matrix is the one thing, the only thing strong enough to defeat Unicron

Unicron is the ultimate force of evil in the universe. He travels from planet to planet devouring and becoming more powerful, more evil. Unicron is forever and has many copies of himself across the multiverse. All are different but all are one in the same, evil incarnate. A being of this power has but one weakness and that is the Matrix. Only the Autobot Matrix of leadership can destroy Unicron, but can something so primal and evil ever be truly destroyed?
