On the planet Cybertron, the Autobot resistance, led by Optimus Prime, is on the verge of losing the civil war against the Decepticons and prepares to evacuate. A Decepticon force, led by Starscream, Soundwave, and Shockwave, intercepts them during the evacuation, and Optimus sends Autobot scout B-127 to Earth on an escape pod in order to set up a base of operations where the Autobots can regroup. B-127 reaches Earth alone, crash-landing in California and disrupting a training exercise by Sector 7, a secret government agency that monitors extraterrestrial activity on Earth. Colonel Jack Burns presumes B-127 to be a hostile invader and pursues him. B-127 scans a Willys MB jeep and flees to a mine, where Blitzwing, a Decepticon Seeker, ambushes him. When B-127 refuses to reveal Optimus's whereabouts, Blitzwing tears out his voice box and damages his memory core; despite this, B-127 stabs and destroys Blitzwing with one of his own missiles. B-127 flees from the soldiers, scans a nearby 1967 Volkswagen Beetle and collapses from his injuries.
