Optimus Prime is a leader in the best sense of the word, taking point on every mission and never sending his team into any situation he wouldn't go himself. Dedicated to the protection of all life and the preservation of freedom for all sentient beings, he serves as a role model for his fellow Autobots. It is through his keen intelligence, even hand, steady nerves and endless compassion that the Autobots continue to frustrate the Decepticons evil plans again and again. In a desperate race against time, Optimus Prime has been forced to send teams of his best soldiers into unknown parts of the Universe in search of the lost Cyber Planet Keys, ancient artifacts with the power to save Cybertron and the rest of the Universe from the giant black hole formed from the implosion of Unicron.
