A year after assuming leadership of the Autobots, Rodimus Prime hosts an intergalactic sporting event, which falls victim to an attack, resulting in the abduction of Spike Witwicky, Kup, and Ultra Magnus. Rodimus is quick to blame the Decepticons, who are divided and weakened by the loss of their leader, Galvatron. But Galvatron's fellow reformatted Decepticons, Scourge and Cyclonus, may have found a way to restore their leader to power. The real culprit may be a new face, but one with a link to the histories of both Autobot and Decepticon, manipulating both sides to take their own revenge.

故事讲述两派来到地球后，因为发生了一些“事件”，导致双方外形大变（也解释了两系列风格不同的原因）。也由于这些“事件”，变形金刚要隐藏于人类社会之中。如何去平衡一切关系是擎天柱作为领袖将要面临的考验，本作品的标题也由此而来。 值得一提的是，本次两派领袖 擎天柱 和 威震天 的配音者是久违的梦幻组合：来自初代动画的 Peter Cullen 和 Frank Welker！他们在阔别电视版的变形金刚作品多年后，再次一起回来共演这双经典的死对头！
