Unicron

The end is nigh, as a planet-sized being that devours worlds locks horns with Cybertron and all of its colonies. The IDW/TF-verse reaches a beyond-epic conclusion, with just about everyone in an all-out battle against extinction, as the universe-shattering threat of Unicron comes to end everything. This bumper-sized volume includes the pathos-soaked final issues of ongoing series Optimus Prime and Lost Light.
