Optimus Prime® is the leader of the Autobots®. Voiced by Peter Cullen in both the original animated series and DreamWorks Pictures' and Paramount Pictures' Transformers. Many years ago, the Matrix of Leadership — a physical piece that Optimus wears inside his chest cavity, the Matrix of Leadership is the "crown" carried by each Prime — "chose" him to be the next Prime, or leader. He humbly accepted, which changed the course of his life from simple working class 'bot on Cybertron to leader of the strongest benevolent force in the Universe, the Autobots®. When leading his team into battle, Optimus Prime's signature phrase is "Transform and Rollout!"
