Revenge of The Fallen - I would never knew that there would be another powerful Decepticon beside Megatron, Galvatron and Unicron. But in the ill fated Revenge of The Fallen; The Fallen was once open a time a prime. His real name was Megatronus Prime from the 13 designated Primes. But he betray his brothers for his own personal gain and tried to destroy a young planet earth. His brothers won the war and outcast him while hiding The Matrix of Leadership that can activate the sun harvester. Seek out on a revenge against The Primes and humanity; he sought his apprentice Megatron to the dark side (sound really familiar).
