Fans have known for a while now, thanks to one of the film's earliest posters, that Optimus Prime will face off against a three-headed dragon-like Transformer in the franchise's fifth outing, Transformers: The Last Knight. Now, thanks to a TV spot released by Paramount Pictures, audiences have their best look yet at the beast, as he soars through the skies in all his glory.

There's not much known about the character created for the movie -- apparently named "Dragonstorm" -- but an advance look at a tie-in toys offers a good glimpse of what the Transformer's robot form looks like, should it appear in the movie.

Take a look at the TV spot below.

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 (Sir Anthony Hopkins); and an Oxford Professor (Laura Haddock).

There comes a moment in everyone’s life when we are called upon to make a difference. In Transformers: The Last Knight, the hunted will become heroes. Heroes will become villains. Only one world will survive: theirs, or ours.

Opening June 21, director Michael Bay’s Transformers: The Last Knight stars franchise veterans Mark Wahlberg, Stanley Tucci, Josh Duhamel, Tyrese Gibson and John Turturro, joined by newcomers Isabela Moner, Liam Garrigan, Jerrod Carmichael, Mitch Pileggi, Laura Haddock, Santago Cabrera and Anthony Hopkins.
