Ngeh??? Dont remember Megatron fighting with someone else, He never had a conflict with Alpha Trion if I'm not mistaken. But ost of it is right. Optimus was then named Orion Pax and even had a girlfriend named Ariel. He at the start was impressed with Megatron and the Decepticons because they could fly while he was just a warehouse worker. He was eventually tricked and later attacked by Megatron because they wanted the warehouse storing energy which he was working at and was badly wounded. Alpha Trion rebuild him into the Autobot named Optimus Prime then.
