Did anyone else feel that Maximals really did win the Beast Wars and not the Predacons?Megatron and Optimus both express that the Maximals lost.True that Megatron took over Cybertron,but he didn't take over because he won the Beast Wars.Megatron had three plans to take over Cybertron that invoided wining the Beast Wars and he failed in all three areas.
The first area was stealing enough energon to power an entire Predacon army so they could destroy the Maximals and take over Cybertron.Things didn't go as planed the Maximals stopped Megatron everytime he was about to get real big amount of it.In one episode Terrorsaur even said they barley had enough to keep themselves and their base powered up.
The second was to steal Vok technology and use it to conquor Cybertron and once again he failed the Maximals always stopped him before he got control of any of Vok's most powerful weapons and lost the second golden disk to boot making it impossible to find anymore Vok weapons.
The third plan was his original plan to go back in time and kill the orginal Optimus Prime before he woke so that the Deceptacons would win the Great War and would led to the Predacons ruling Cybertron in the future.He came close to doing so he still failed to change time.By the end of the Beast Wars Megatron lost his soilders,his base,and lost a all powerful Deceptacon battle ship to boot.He was captured in tied up to the Autobot ship Omega Delta.Megatron escaping and surviving the transwarp was pure dumb luck.
Here's how I see it Megatron escaped the transwarp and some how made it back to Cybertron ahead of the Maximals.So Megatron goes into hidding and some how comes up with the idea to create a transforming locking viruis(one that de-evolves transmetals)and create a new race of transformers to replace Maximals and Predacons.Since no one knew Megatron was still on the planet or that this version of himself(his past self could have still been on Cybertron) He wasn't being opposed by anyone until he developed the virius and at least some Vehicons.And didn't strike until his past self stole the golden disk and left Cybertron so he wouldn't indanger his own existense.My point is he wouldn't have done any of that if the Predacons had actually won the Beast Wars,the way he took over Cybertron seemed to totoally contrdict his original plans.
