For eons, a race of massive, intelligent robotic beings called The Transformers have waged terrible war. Hailing from a world known as Cybertron, two factions, the Autobots and Decepticons, waged terrible war in search of the element which gave them life, Energon. As the Autobots desperately searched on other worlds for Energon, their enemy would surely follow. The Ark-1 crash lands on a mysterious, primitive world, Earth, leaving its Autobot and Decepticon inhabitants unconscious for four million years.
When they awaken, their war is ignited anew... only this time, Earth has developed new life-forms. Unfortunately for these Cybertronian warriors, its life forms have grown significantly since they landed. The Transformers are the size of mere toys to the inhabitants. A few minutes after exploring this world, the great and mighty leader Optimus Prime found himself trampled underfoot. Luckily not crushed by the weight of the organic, he was subsequently discovered and taken home by the gargantuan alien, her reasons were not made clear.
Now they must find a way to survive on a world full of giants, searching for a way home.
