The new trailer for Michael Bay‘s final Transformers movie has arrived, and it looks like Transformers: The Last Knight is bringing the Bay-sanity to a whole new level! It also appears that Bay is taking some of his cues for this film from the beloved Transformers: The Movie from 1986. What does it all mean? Transform and roll out as we uncover the truth on today’s Nerdist News.

Join host and triple changer Transformer, Jessica Chobot, as she channels the AllSpark to breakdown some of the trailer’s biggest moments. Naturally, there are some pretty big spoilers ahead—so consider yourselves warned!

First up, we’ve finally got Unicron in the live-action Transformers universe—it only took three decades for the biggest of all of the Transformers’ big bads to make his return to the silver screen. He’s basically the Transformers’ Galactus, but he’s no space cloud in this movie. In fact, it appears that some of the action from the trailer is actually taking place on Unicron himself, which should give you an idea of just how huge he is in actuality.

The trailer also revealed a pretty dark-seeming turn for Optimus Prime. As if his battle with Bumblebee didn’t tip you off, it appears that everyone’s favorite Autobot leader may be one of the film’s villains. Note the purple eyes that Optimus has in the trailer, as opposed to his normal blue eyes. We’re thinking that Unicron may have corrupted Prime to make him his servant…which kind of makes him the Galvatron of this movie. But who can stand up to evil Optimus?

Why, Hot Rod, of course! That’s right, another character from the ’86 Transformers is getting a big screen comeback. And if our guess is correct, we’re not only going to see Hot Rod become Rodimus Prime, we may also see a more definitive death for Optimus himself!

Also, we’re offering up a few thoughts on Sir Anthony Hopkins‘ new human villain and the new evil organization. Plus, where the hell is Merlin?! We know he’s in this film, we just want to see what he looks like!
