Bad Batch TV Talk 2X05 Entombed

While searching a junkyard for useful salvage, Omega and Wrecker find an ancient compass containing a set of coordinates toward the uncharted Kaldar Trinary that carry the promise of treasure. Phee Genoa and Omega persuade the Bad Batch to set out for the system, where the compass leads them to Skara Nal, the resting place of a legendary crystal, the Heart of the Mountain. They find the stone, but upon removing it, Skara Nal is revealed as an ancient doomsday mech, which begins running amok. The Bad Batch and Genoa manage to return the crystal, which deactivates and destroys the machine.
