A couple days ago I introduced a new fan series called Transformers Rebirth. I mentioned that the new bad guy were lead by a Cybertronian-sized version of Unicron, called Lord Unicron. He leads the Heralds of Unicron, replacing the Decepticons, but two of the original (Cyclonus and Scourge) remain but they are REALLY OLD. Lord Unicron returned by Soundmaster resurrecting him. He went on to take the body of a dead Decepticon soldier. Now, he is not able to destroy planets like he used to do, but is still as powerful.
