Monocle

Monocle could be considered one of the mysterious ghost vehicles, but for a different reason. He and his companions on the Exploration Team stayed on the Moon after most of the other Mini-Con robots left because they wanted solitude and quiet contemplation. They spend most of their time on the dark side of the Moon, where few humans go, and are occasionally spotted by explorers driving across the empty landscape, or meditating on the floor of an old crater. Their peace is disturbed only by the disruptive aggression of Scattorbrain and the other members of the Lunar Assault Team.
