I know that he's not. As the mythology seems to go (according to my understanding at least) Megatron took his name from Megatronus- The Fallen- one of the original 13. However, what if Megatron- Optimus' old foe- was actually Megatronus-The Fallen- 1 of the 13- himself? Would that make for a better story / mythology? Cheapen it? No effect?
