Fiction

Marvel comics continuity

Before the launch of the Ark, Grapple, Hoist, Smokescreen, Skids, and Tracks volunteered to have their memory engrams transferred to crystalline containment vessels, to serve as additional soldiers for the Autobot crew as needed. The vessels were stored in the mind bank.

The Ark crash-landed on Earth, where the crystalline containment vessels were left undisturbed. Four million years later, the main crew awoke, but were almost all injured by a surprise attack by Shockwave. Optimus Prime, realizing the need for more troops, had Wheeljack set up the mind bank to transfer the five Autobots into bodies newly constructed by the Ark. Once the transfer process was complete, Optimus Prime remarked that the five now lived, for a second time. Rock and Roll-Out!
