For ages, they have hidden among us, moving freely, influencing the growth of our society and culture.
They look like us. They sound like us. But really, they're just ... Pretenders.
When the sudden re-emergence of their Decepticon foes forces the Autobot Pretenders, Earth's secret protectors, to shed their human disguises and go to war once more, Earth becomes battleground that must be defended by its own inhabitants. As the conflict escalates, human beings are recruited by both sides, and, imbued with the power of the Masterforce, become Transformers themselves, merging with Transtector bodies to join the fight. But behind it all, there is an even more sinister force manipulating events, which will culminate in the creation of the most powerful super-robot lifeform ever ... the Godmasters!
