Along with Backbite and Darklight, Umbra invaded the Chamber of the Ancients in Iacon, just as Optronix accepted the Matrix of Leadership and became Optimus Prime. After killing a guard and literally disarming Skids, Umbra transformed into his energy rifle mode and lent himself to Darklight. Knocked away by Prime, he transformed back to robot mode and attacked the Autobot leader again and accidentally slew Darklight. With both of his comrades dead, Umbra was briefly interrogated by Prime. He cryptically warned the massed Autobots of 'impending doom from below' before messily committing suicide with acid.
