Oh no no no no no.
Optimus Primal =/= Optimus Prime
I watched some Beast Wars too. But no. That's not the original series. ^_^
You are wrong there. :P
Beast Wars had a slow transformation (<.< Only useable word) into transformers. They had a series after Beast Wars when they were mechanical-looking animals, some sort of event I can't remember ended them up waking up in that state, and then progression through that series ended them up on earth as vehicles.
