Over the past few days, new photos of the Autobots in Transformers: The Last Knight have been released through the sequel's official Twitter. We've shown you a closer look at the new Vespa scooter Autobot Sqweeks, along with Crosshairs, Drift, Hot Rod and, of course, Optimus Prime. Today we have one more Autobot to unveil, Hound, along with the Decepticon leader Megatron and the evil cop car Decepticon Barricade. If that wasn't enough, we also have a new video featuring returning star Josh Duhamel.

Like the previous photos released on Twitter, we get some key stats for Hound and his Decepticon enemies Megatron and Barricade. For instance, Megatron is the tallest of this trio, standing 30 feet tall, while Hound is just 24 feet tall and Barricade is 16 feet tall. Hound is described as a "boisterous Autobot commando" who "always has his finger on a trigger." Barricade is a "duplicitous Decepticon sentry," who is sent to "punish and enslave," instead of to protect and serve like a regular cop. Megatron is the "ruthless Decepticon oppressor" who seeks "peace through tyranny."

The official Transformers 5 Facebook also released a new video this week with Josh Duhamel, who returns to reprise his role from the original trilogy as Lennox, after sitting out Transformers: Age of Extinction. This video features the actor at Luke Air Force Base in Glendale, Arizona, and although we don't exactly know what they're shooting there, we get a brief glimpse at director Michael Bay, while Josh Duhamel reveals how proud he is to be at this Air Force base. Hopefully we'll get many more videos as production continues on this epic action sequel.

The Last Knight centers on Optimus Prime, who has been searching through the cosmos for the Quintessons, the beings believed to be responsible for the creation of the Transformers race. Meanwhile back on Earth, Wahlberg's Cade Yeager will be facing a new alien threat that brings Josh Duhamel's Lennox and Tyrese Gibson's Epps back into duty. Isabela Moner is playing the female lead, though no character details have been revealed. Jerrod Carmichael (NBC's The Carmichael Show) has also come aboard in an unspecified supporting role, possibly serving as this sequel's comedy relief.

Michael Bay is directing from a script by Iron Man writers Art Marcum & Matt Holloway. They are joined by Black Hawk Down writer Ken Nolan on the screenplay. The team were part of Paramount's writer's room that generated several ideas for Transformers sequels and spinoffs. Original trilogy stars Josh Duhamel returns as Lennox along with Tyrese Gibson as Epps. While the actors starred in the original trilogy, Transformers, Transformers: Revenge of the Fallen and Transformers: Dark of the Moon, they didn't return for 2014's Transformers: Age of Extinction. Tae a look at Crosshairs from Transformers: The Last Night, arriving in theaters on June 23, 2017, along with a promo image from Transformers: Age of Extinction that shows how little Crosshairs has changed.
