With the destruction of MEGATRON, OPTIMUS PRIME thought he was finally, after millions of years, at peace. Little did he know that the escape of STARSCREAM would draw dozens of new DECEPTICONS to Earth. The desire that burns brightest in his Spark is that the war will soon end. He is determined to see that end come, and so he works with his human comrades and the other AUTOBOTS to hunt the DECEPTICONS that have come to Earth, and destroy them, one by one.
