The Centurions are called to defend Ice Castle, an arctic spy outpost which is under attack by Doc Terror. When his ground forces fail, Terror retreats with Hacker to Dominion via a secret tunnel. Back at Dominion they switch to strafer mode and return to the battle at Ice Castle. But something strange happens...their normal cyborg units fuse together to become ""Uniborg."" When Terror and Hacker again return to Dominion, they are evicted by Uniborg and forced to flee through the same tunnel to Ice Castle...where the Centurions are waiting. Terror and Hacker are tried, convicted and sent to a rehabilitation facility. During this time, Uniborg begins producing new and improved Doom Drones, and soon releases them on Sand Castle, a spy outpost in the Caribbean. The Centurions find themselves in real trouble as they face the new breed of Doom Drones. Science Lesson: The two halves of the brain by Crystal.
