The Lunar Shield is a relatively new faction made of up various heroes from different worlds in the wake of the vehicon invasion of the Tower of Twilight by the Decepticons. It has formed in almost entirely in reaction to recent chaos, turmoil, and open warfare on the moon. As the Moon, Tower and Flotilla are key hubs of the Multiverse, and the Shy Guys have lost the dominion they once had, the founders of the Shield thought it necessary for these sectors to have a dedicated police force.
