Big Convoy, also known as Big Primal, is a high-ranking yet severely anti-social general in the Maximal army. He is often called by his nickname, "the One-Man Army", due to his isolationist behavior and immense skill in battle. He can transform into a woolly mammoth, and his weapon of choice is the aptly named Big Cannon. At one point, he was a freelancer, working with Rockbuster, until he joined the Maximal army officially. He has a heated but respectful rivalry with the Predacon Emperor of Destruction, Magmatron. The Maximal Elders recognize Big Convoy's skill and dedication, yet do not approve of his introverted attitude. He carries an Energon Matrix connected to the Vector Sigma supercomputer.
