The Master Builder
Oct 7, 198522mRating 5.7
The Constructicons trick Grapple and Hoist with claims of having left Megatron. They construct a tower Grapple thought up to absorb solar energy, which Optimus Prime did not want to be built for fear of The Decepticons getting their hands on it. Not surprisingly, The Constructicons betray them.
