I bought this toy maaaany years ago at a local anime and import toys shop that I still go to often. It was obviously Beast Wars Optimus Prime, and was a top notch figure if not outright one of the best Transformers toys ever at the time. I couldn't help but wonder what crazy story there was for how ancient master bad-ass Optimus Prime ended up in the Beast Wars, how he lost his left arm (it is a more robotic replacement arm), and how he ended up being a Maximal. I loved that he kept his huge size as a mammoth too. Well of course later I found out that he was just another Optimus-looking new BW Character in Neo, and his name was Big Convoy... F**k that. I finally repainted him, so he is definitely Beast Wars Optimus Prime now to me. Almost full repaint (except some of the chest and back) and 4 new missiles permanently installed.
