In the midst of their mission, Onix, Blitzwing, Lugnut and the voiceless Starscream encounter a large arrangement of Autobots who seek to protect the Space Bridge equipment and destroy any Decepticon in their way. Tagging along with them is Sentinel Prime himself, who decides to take Onix head-on. Will this turn out as easy as Onix claims it to be? Or will things take a toll on her and her comrades?
