Transformers: Cybertron

Transformers: Cybertron, known in Japan originally as Transformers: Galaxy Force (トランスフォーマー ギャラクシーフォース), is the 2005-2007 Transformers toy line and animated series, another co-production between Hasbro and Takara. It was aired in Japan as a separate rebooted transformers series, though in America, the English dub was presented as a sequel to the previous series, Transformers: Armada and Transformers: Energon by adding dialogue and reusing a number of screens to link elements of the Armada and Energon series to the show, giving the impression that it is a sequel. In the anime, all of the Transformers are computer-generated, while the humans and backgrounds are rendered in traditional cel animation. It is the last series in the Transformers franchise to be produced in Japan until Transformers: Go!.

Plot

When the destruction of Unicron results in the formation of a massive black hole, the planet Cybertron, home world of the Transformers, is threatened, and its population is evacuated to Earth, taking the forms of local vehicles and machinery to hide from humanity. As this occurs, Optimus Prime's elite team of Autobot warriors are approached by the ancient Transformer Vector Prime, who has emerged from his resting place in the void outside of time to inform them of the legendary Cyber Planet Keys, ancient artifacts of power which can stop the black hole and save the universe. Lost due to an accident during an attempt to create a cross-universal space bridge network, the Cyber Planet Keys now reside on four worlds somewhere in the universe - unfortunately, Vector Prime's map showing their location is stolen by Decepticon leader Megatron, and both forces relocate to Earth as the race to find them begins.
