'Transformers': Check Out Optimus Prime's Surprising New Look

The Autobots leader gets a brand new look for 'Age of Extinction.'

The human roles in "Transformers" aren't the only characters getting revamped for "Age of Extinction." The leader of the righteous Autobots has an updated look as well.

Gracing this cover of the January issue of Empire magazine are Mark Wahlberg, Jack Reynor, and Nicola Peltz, the three new leads in the "Transformers" series, alongside Optimus Prime, who is sporting a new, tougher look for the fourth entry in the franchise.

Whereas Optimus Prime had a fair amount of color in the first three "Transformers" movies (orange and red flames with bright blue background), the new version looks more washed out. Much of his color, especially on his chest, is gone. His look is harsher than his original softer expression around his eyes, but the "Age of Extinction" model sports a more furrowed brow that gives the character an edge.

The other big difference is the large sword that Optimus wields in his right hand. This isn't the first time that the Autobots leader has brought a blade into battle. In the destructive finale of "Dark of the Moon," he had orange blades extending from his wrists, but here, he's clearly holding onto his new saber.

"Transformers: Age of Extinction" is the fourth film in the series directed by Michael Bay, and it follows an all-new cast of characters. Wahlberg plays an inventor who finds himself involved with the warring mechanical alien races, alongside his daughter, played by Peltz, and the young man who is after her heart (Reynor).

"Transformers: Age of Extinction" opens in theaters on June 27, 2014.
