Whoops I'm wrong - did a quick search and as it turns out, I didn't have Omega Supreme. So then I though oh I must have Fortress Maximus...double wrong! The big transforming base robot that I have is in fact, Metroplex: http://en.wikipedia.org/wiki/Metroplex_(Transformers
) . But my brother did have Trypticon. Amusingly, Wiki says that they've fought each other in the show, often using wrestling moves. nice.
The guy in the trailer is definitely Omega Supreme though. Omega Supreme. Sounds like an Arby's sandwich. Bacon Delux.
