Transformers #5 (Marvel, 1985) features Shockwave seizing control of the Ark, reviving the Decepticons, and stringing up the deactivated Autobots for parts. He declares himself leader over a recovering Megatron, planning to use Optimus Prime's Creation Matrix to create new Decepticon warriors. Buster Witwicky and Ratchet arrive to discover the horrifying scene, finding Optimus Prime's severed, yet still-living, head, who declares Buster the Autobots' last hope. This issue is significant as it establishes the series as an ongoing title and boasts the first iconic cover appearance of Shockwave.
