As they waited, the Autobots soon sensed that the ions drifting through the air had become unusually active.
"Leader, an enormous energy source has been activated in New Iacon City, more than forty kilometers to the northeast!"
Ratchet raised a hand high. A slender, antenna-like joint rapidly extended from it, spun continuously in the air for a moment, then pointed northeast.

During the Cybertronian Civil War, the Autobots had once used this technology to ruthlessly suppress the Decepticon Corps for a time.
It was only after Shockwave and the other Decepticon Corps scientists had grasped its basic
