In G1 they mention that the Constructions created Megatron but I remember reading somewhere i will get you guys the link or even the paragraph of where it is mentioned. It says that Liege Maximo created Megatron along with Soundwave and Shockwave. Here's the paragraph: "Liege Maximo created Three new Decepticons and took them to Vector Sigma to give them Life. They declared themselves: "Soundwave", "Shockwave" and the largest and strongest "Megatron". These Decepticons were also given the newly developed and top secret ability of personal flight These Decepticons were the first of a new army that would plunge Cybertron into the most destructive war yet, The 3rd Cybertronian War, also known as The Great War. Megatron slew Sentinel Prime, in hopes to steal the Matrix for himself, but the Matrix had known of Megatron's plan, and had been secreted away by the oldest living Autobot, Alpha Trion.." What do you guys think?
