OUR WORLDS ARE IN DANGER. So begins the introduction of the Transformers: Cybertron animated series, where Autobot leader Optimus Prime lays out the premise of the show -- how the quest for the four Cyber Planet Keys may define victory in the war against the Decepticons.
Optimus Prime, mirroring his design from the very start of the franchise, turns into a red and blue truck -- the water and foam cannons on the trailer tell us he's a firetruck -- though in this case, the design is utterly fanciful and futuristic. In classic Prime fashion, the cab turns into a robot (which inspired his Legends of Cybertron figure), while the trailer becomes a weapons emplacement. Prime can combine with his trailer accessory to become a super robot (pictured here), where the trailer gives him jetpack wings and two heavy cannons.
Prime has lights and sound features, and extra pop-out weapons when his Cyber Planet Key was plugged in. He could also combine with a few other Cybertron-series toys, as we'll see soon enough. This Prime is notable also for having an Autobot Matrix of Leadership in his chest compartment, carrying forth that piece of Cybertronic lore from the 1986 movie. Optimus Prime was available starting in 2004.
