Great Shutdown

The Great Shutdown is an event from the Dreamwave comics continuity.

Taking place approximately 1205 vorns after the launch of the Ark, the Great Shutdown marked the end of conflict on Cybertron for a staggering 46,592 vorns. During this time all known Cybertronians on the planet were in an enforced statis lock, rendering them inoperative.

The exact reasons for the Great Shutdown remain a mystery but the basic belief is that despite attempts to conserve energy, such as Micromaster technology, Cybertron's energon completely dried up, and Transformers all across the planet simply began to shutdown as they entered a pre-programmed period of hibernation.

After about 36 vorns, Shockwave was reactivated and began awakening others bringing the Great Shutdown to an end.
