I've read a few comments on these boards as well as elsewhere concerning the idea that Megatron and Optimus are truly brothers (not in a figurative sense) and that Megatron is/ was a Prime. It seems as if this idea originates with Optimus' words to the befallen Megatron in the first Transformers film, You left me no choice, brother. I always believed that he was speaking figuratively, as in my fellow Cybertronian. However, some people have apparently taken it seriously. Even the Transformers Wiki treats this idea as canonical fact. Link So, is this idea cannon or is it just fan-fiction?
