New trailer of "Transformers: The Last Knight" is out, featuring many actions in nearly post-apocalyptic world and putting a highlight on strong teenage female protagonist Izzy, played by former Nickelodeon star Isabela Moner. The trailer also brings back Mark Wahlberg's Cade Yeager, Bumblebee and the beloved robotic tyrannosaurus, Grimlock.

The new trailer opens with kids exploring a shattered football stadium to examine some dead Transformers. They meet Izzy, who is later talking to the viewers through the camera and saying that she used to be a normal kid before her world fell apart. She is now a bold fighter with a connection to the Autobots.

Izzy eventually meets up with Cade, who doesn't really approve her decision of fighting. "You think you're a badass? 'Cause it's okay to be a kid, little J.Lo," says Cade. However, he stays to fight with her anyway.

The end of the trailer sees Grimlock eating busted cars, much to Cade's anger. He orders Grimlock to drop it and the Dinobot obeys him by dropping the busted cars from inside its mouth. Izzy, meanwhile, finds it very funny and laughs at the Dinobot.

"The Last Knight" shatters the core myths of the "Transformers" franchise and redefines what it means to be a hero. Humans and Transformers are at war, Optimus Prime is gone. The key to saving our future lies buried in the secrets of the past, in the hidden history of Transformers on Earth. Saving our world falls upon the shoulders of an unlikely alliance: Cade Yeager (Mark Wahlberg), Bumblebee, an English Lord (Anthony Hopkins) and an Oxford Professor (Laura Haddock).

"Transformers: The Last Knight" is set to hit U.S. theaters on June 23.
