Charles Rochester was the leader of the Mars Zeon force that launched the attack on Earth. He also commanded the Charles Fleet. He fought Bergh Scred's F90 Gundam F90 and later the F91 Gundam F91 numerous times in the Oldsmobile War. When the Charles Fleet was wiped by the Earth Federation Space Force, he rallied what remained of his forces and became part of the Crossbone Vanguard's Charles Air Attack Force. Though he knew he was merely a pawn for the Crossbone Vanguard's bigger plan, he continued to fight his enemies until the end of the war.
