Riding into battle alongside the heroic giant robots from Cybertron will be their titanic new allies, the Dinobots.
This reptilian team is certainly one of the highlights of Transformers: Age Of Extinction, the fourth instalment of the movie franchise that opens here tomorrow.
While the Dinobots' origins in Michael Bay's movie have been a closely-guarded secret, the original Dinobots - a team of five consisting of Grimlock, Slag, Sludge, Swoop and Snarl - had two different origin stories from the cartoon series of the 80s, as well as the comics. The cartoon depicted the Dinobots as a powerful but dim-witted team of Autobots, built on earth by the scientist Wheeljack, who was inspired by dinosaur fossils.
In the comics, they were elite Cybertronian warriors who received dinosaur forms to combat the one-eyed Decepticon Shockwave. No matter what the origin, a few things are constant when it comes to the Dinobots.
Led by the fearsome Grimlock, who transforms into the giant fire-breathing metallic Tyrannosaurus rex that Optimus Prime is seen riding in the movie's trailers, these mechanical monster lizards are a crack commando unit who specialise in one thing: massive metallic mayhem.
KNOW YOUR DINOBOTS
The leader of the Dinobots might be arrogant, but he has the might to back it up. While the movie will see him wield the massive Dragontooth mace, Bay's version of Grimlock can still breathe fire in T-rex mode. Expect this version to retain the caveman-style speech from the cartoon that became a trademark characteristic of Grimlock.
