The term "Unicron's Spawn" refers to a secret society formed by those who were created by Unicron, the Dark God and Chaos Bringer. They have infiltrated into many divisions of Cybertron's society in the Beast Era. They are waiting for the right time to wage a war against the Cybertronians, the children of Unicron's enemy Primus, including the Autobots, Decepticons, Maximals, and Predacons. Their ultimate goal is to see the return of their master, Unicron.
