In the original Pacific Rim, a Breach opened at the bottom of the Pacific Ocean, and through it emerged giant Kaiju, monsters engineered by the alien Precursors to move from dimension to dimension terraforming planets—exterminating the indigenous species and taking full territorial control. These Kaiju unleashed their fury on coastal cities along the Pacific Rim, and proved virtually unstoppable with conventional weapons. Giant robotic warriors called Jaegers—piloted by humans connected by a neural bridge—were engineered to fight back. Jaeger Gipsy Danger successfully closed the Breach by detonating a nuclear bomb, helped by legendary Jaeger Marshal Stacker Pentecost, who gave his life to ensure the success of the operation.
