Shia LaBeouf and Megan Fox kick-started the ever-changing Transformers franchise before passing the baton onto a range of new stars who have overseen its evolution into a range of new forms.

Cut to 2024, and with Transformers One due out on 11 October, the series has changed yet again, this time with an animated tilt. If you’re struggling to keep up with the story so far then fear not, here’s everything you need to know to help get you caught up before you sit down to enjoy the franchise's latest offering.

Released in 2007, the first Transformers movie was directed by Michael Bay and starred LaBeouf as Sam Witwicky, a young man who — together with his soon-to-be girlfriend Mikaela, played by Fox — gets embroiled in a long-running war between an alien race of shape-shifting robots.

Leading the good side are the Autobots, led by their heroic leader Optimus Prime and his band of scrappy heroes, among whom is Bumblebee who transforms into a yellow vehicle.

Leading the evil side of things is Megatron, the Decepticon leader who is determined to capture a powerful object known as the AllSpark and reignite the life of their doomed home planet of Cybertron and end their species’ ongoing war.

After emerging victorious in part one, Sam, Mikaela, Prime and Bumblebee returned for Bay’s 2009 sequel, Revenge of the Fallen. Here, we find Sam plagued with visions of mysterious Cybertron symbols which we eventually discover are linked to a new Decepticon enemy known as The Fallen who wants to get his metallic hands on a new, powerful energy source that will ultimately destroy life on Earth.

Two years later, Bay and LaBeouf returned with 2011’s Transformers: Dark of the Moon, this time without Fox’s character Mikaela. In part three, we find our heroes — both human and robot — in the endgame of the Autobot and Decepticon war. With a new power source discovered abandoned on the Moon, good fights it out with evil once more in order to save the future of both Cybertron and Earth.

During the adventure, we meet a new character, the Autobots’ previous leader, Sentinel Prime, who many believed was long dead. However, after being revived, our heroes learn the hard way that his heroic days may be behind him.

In 2014’s Transformers: Age of Extinction, Bay passed the baton to a whole new cast led by Mark Wahlberg’s inventor single dad Cade Yeager.

He’s joined by new franchise stars Jack Reynor, Nicola Peltz, Kelsey Grammar and Stanley Tucci and a range of new Transformers characters, including Dinobots. Story-wise, the Autobots are still fighting for their lives, this time from a bounty hunter with mysterious links to Megatron, here in a new form known as Galvatron.

In 2017’s Transformers: The Last Knight, Sir Anthony Hopkins joins the franchise alongside returning faces like Wahlberg and a handful of characters from the first three movies, including John Turturro’s government agent Seymour Simmons.

With the Transformers still living as refugees on Earth, Yaeger spends his days helping as many as he can before discovering a new element of the story via Hopkins historian and astronomer Sir Edmond Burton. With the future of Earth once again on the line, humans and robots must join forces to secure the future of both species.

A year later in 2018, Hailee Steinfeld and John Cena joined the franchise for Bumblebee, a spin-off movie set in 1987 that acted as a prequel to Bay’s 2007 original and chronicled the character’s arrival on Earth and first Earth-based brush with the Decepticons.

It was the first movie of the series not to be helmed by long-time Transformers director Bay and instead spearheaded by Travis Knight.

Set in 1994 after the events of Bumblebee but before the adventure captured in the first Transformers movie, Transformers: Rise of the Beasts is a sequel to both the primary series timeline and its Bumblebee spin-off.

We’re introduced to a group of archaeologists who find themselves in the middle of the Transformers’ ongoing war, this time with three new species of robot joining the fight: Maximals, Predacons and Terrorcons.

2024’s animated Transformers One is a prequel set three billions years before the events of the live-action films. The film tells the origin story of Optimus Prime and Megatron, and features an all-star cast including Scarlett Johansson, Chris Hemsworth and Brian Tyree Henry.
