When a space-time rift materializes near the Quintesson homeworld, its merciless warriors set off to establish a new home planet - and their target is Cybertron! Cunningly manipulating the Autobots and Decepticons into battle and intending to pick off the survivors, the Quintessons in fact unite the old enemies... and then it's classic, all-out action all the way, especially when Rodimus Prime, Metroplex, and Ultra Magnus join the fray!
