The Maltos and Autobots search Cybertron for their missing allies. Thrash steps up to help his struggling sister lead this critical mission, but tension divides the team when they need unity most. Meanwhile, Robby and Mo find a new friend, and Optimus finds an old enemy.
Many years after the end of the civil war between the Autobots and the Decepticons, the Malto family relocates from Philadelphia to the small town of Witwicky, Pennsylvania. There, young Robby and Mo Malto witness the birth of a new breed of Transformers called Terrans, who become bonded to the two via special cyber-sleeves on their arms. Now adopted into the family and being mentored by Bumblebee, the Terrans work with the children to protect their new life and find their place in the world.
