Blizzard Planet apparently has blizzards.
After assuming control of Unicron, Shockblast was driven crazy by the power, and went on a mindless rampage, causing him to crash on Blizzard Planet. Optimus Prime engaged in combat with Shockblast, attempting to reach out to him. Some sense was talked into Shockblast, Unicron brought down one of his arms on the planet's surface and crushed the Decepticon.
Then Unicron ate it.
