Atomic Rex: Ballad of Bravura - Paperback

Prior to the kaiju leaving the microcontinent on which they were spawned, several countries laid claim to the newly discovered landmass. In an effort to gain control of the island, two superpowers sent their newest weapons of war in the form of giant mechs into the area. These prototype mechs were piloted by humans and were able to greatly enhance the soldiers' capabilities on the battlefield. When the two forces came into conflict, their battle awakened the True Kaiju whom the world would come to know as Atomic Rex! The nuclear nightmare laid waste to all but two of these early mech models, before beginning his domination of the western hemisphere.
