Countdown is a legend on thousands of inhabited worlds. Before all the other Autobots, he had gone out into space to explore, travelling from one end of the galaxy to the other, and overthrowing tyrants and monsters wherever he found them. Countless beings owe Countdown their freedom. Now, he identifies planets under threat from the Decepticons and meddles to the Autobots' benefit. He looks forward to the day when the Decepticons are defeated, and he can start toppling.
