Resurrected by the planet-consuming Unicron to serve as a primary agent, Megatron, known as Galvatron in this new form, was forged with a specific purpose. Unicron's influence remained, an incomplete restoration that created a complex and volatile dynamic between them. His mission was the acquisition of Energon, a critical power source, undertaken on behalf of Unicron and Alpha Q to reconstruct consumed worlds. Yet his own ambition for personal power was a consistent and driving motive that often took precedence. This led to a strategic, self-serving partnership with the Terrorcon forces and Alpha Q, a relationship characterized by manipulation and a clear focus on achieving dominance. A pivotal transformation occurred when he seized control of the massive super-weapon, the Sun Storm, and successfully harnessed its immense power. This act marked his defiance, shedding the influence of Unicron, reverting to his original identity, and declaring independence to solidify a path of conquest based on a belief in absolute power. His relationship with Starscream was particularly notable. After Starscream's own resurrection left him incomplete and serving as an amnesiac assassin for Alpha Q, Megatron later wiped his mind completely. This action transformed Starscream into an utterly loyal and subservient lieutenant, erasing all previous autonomy. His leadership involved the constant pursuit of enhanced power through advanced technology and the exploitation of subordinates. He deployed combiner teams and powerful warriors like Shockblast on missions to defeat Autobot forces and secure strategic advantages, waging extensive military campaigns for control of Energon resources and direct assaults on Cybertron and Earth. A central aspect of his narrative was the profound rivalry with Optimus Prime. Their conflict featured numerous direct confrontations, including one where he forced Optimus Prime to his knees, only to be bested when his opponent combined with Wing Saber to achieve a new level of power. Following a prior defeat and a period of absence, his return to power involved ending an internal Decepticon conflict and brutally reasserting his authority over the faction. His narrative concluded with a final, decisive confrontation that led to his defeat, cementing the outcome of the long-standing war.
