Grapple's pride over designing a solar energy tower is dampened when Optimus Prime decides that the device is too difficult to defend from the Decepticons. Defying Prime, Grapple persuades Hoist and the Constructicons to build the tower anyway. Unfortunately, the Constructicons' claims that they have deserted the Decepticons prove to be false. Written by David N. Gottlieb and Herb Engelhardt, "The Master Builders" first aired in America on October 8, 1985. ~ Hal Erickson, All Movie Guide
