The Master Builder

The Constructicons suddenly get the drop on the desert-bound Grapple and Hoist. However, they claim to not be looking for a fight, but instead looking to help in the Autobot cause. They prove their newfound loyalties by using their skills on Grapple's powerful solar energy-collection tower schematics. Grapple is thrilled at the opportunity, especially since Optimus turned it down earlier. The Constructicons are lying and Megatron plans to use the powerful tower for himself.
