Fiction

Transformers: Generation 1 (1984–1993)

Generation 1 is a retroactive term for the Transformers characters that appeared between 1984 and 1993. The Transformers began with the 1980s Japanese toy lines Micro Change and Diaclone. They presented robots able to transform into everyday vehicles, electronic items or weapons. Hasbro bought the Micro Change and Diaclone toys, and partnered with Takara. Marvel Comics was hired by Hasbro to create the backstory; editor-in-chief Jim Shooter wrote an overall story, and gave the task of creating the characters to writer Dennis O'Neil. Unhappy with O'Neil's work (although O'Neil created the name "Optimus Prime"), Shooter chose Bob Budiansky to create the characters.

The Transformers mecha were largely designed by Shōji Kawamori, the creator of the Japanese mecha anime franchise Macross (which was adapted into the Robotech franchise in North America). Kawamori came up with the idea of transforming mechs while working on the Diaclone and Macross franchises in the early 1980s (such as the VF-1 Valkyrie in Macross and Robotech), with his Diaclone mechs later providing the basis for Transformers.

The primary concept of Generation 1 is that the heroic Optimus Prime, the villainous Megatron, and their finest soldiers crash-land on prehistoric Earth in the Ark and the Nemesis before awakening in 1984, Cybertron hurtling through the Neutral zone as an effect of the war. The Marvel comic was originally part of the main Marvel Universe, with appearances from Spider-Man and Nick Fury, plus some cameos, as well as a visit to the Savage Land.

The Transformers TV series began around the same time. Produced by Sunbow Productions and Marvel Productions, later Hasbro Productions, from the start it contradicted Budiansky's backstories. The TV series shows the Autobots looking for new energy sources, and crash landing as the Decepticons attack. Marvel interpreted the Autobots as destroying a rogue asteroid approaching Cybertron. Shockwave is loyal to Megatron on the TV series, keeping Cybertron in a stalemate during his absence, but in the comic book, he attempts to take command of the Decepticons. The TV series would also differ wildly from the origins Budiansky had created for the Dinobots, the Decepticon turned Autobot Jetfire (known as Skyfire on TV), the Constructicons (who combine to form Devastator), and Omega Supreme. The Marvel comic establishes early on that Prime wields the Creation Matrix, which gives life to machines. In the second season, the two-part episode The Key to Vector Sigma introduced the ancient Vector Sigma computer, which served the same original purpose as the Creation Matrix (giving life to Transformers), and its guardian Alpha Trion.

Robots in Disguise (2000–2001)

First broadcast in Japan in 2000, Robots in Disguise was a single animated series consisting of thirty-nine episodes. It was exported to other countries in subsequent years. In this continuity, Megatron re-creates the Decepticons as a sub-faction of the Predacons on Earth, a potential reference to the return to the vehicle-based characters following the previous dominance of the animal-based characters of the Beast eras. It is a stand-alone universe with no ties to any other Transformers fiction, though some of the characters from Robots in Disguise did eventually make appearances in Transformers: Universe, including Optimus Prime, Ultra Magnus, Side Burn and Prowl.

The show was heavily censored in the U.S. due to its content of buildings being destroyed and terrorism references after the September 11 attacks on the United States and three episodes were cut altogether.

The Unicron Trilogy (2002–2006)

These three lines, launched in 2002 and dubbed the "Unicron Trilogy" by Transformers designer Aaron Archer, are co-productions between Takara and (lesser extent) Hasbro, simultaneously released in both countries, each lasting 52 episodes. Armada followed the Autobots and Decepticons, discovering the powerful Mini-Cons on Earth, which are revealed by the end to be weapons of Unicron. Energon, set ten years later, followed the Autobots and the Omnicons in their fight to stop the Decepticons and the Terrorcons from resurrecting Unicron with energon.

In Japan, the series Transformers: Cybertron showed no ties to the previous two series, telling its own story. This caused continuity problems when Hasbro sold Cybertron as a follow-up to Armada/Energon. The writers attempted to change certain plot elements from the Japanese version to remedy this, although this largely added up to nothing more than references to Unicron, Primus, Primes and Minicons.

Just as Marvel produced a companion comic to Generation 1, Dreamwave Productions published the comic Transformers Armada set in a different continuity from the cartoon. At #19, it became Transformers Energon. Dreamwave went bankrupt and ceased all publications before the storyline could be completed at #30. However, the Transformers Fan Club published a few stories set in the Cybertron era.

Transformers: Universe (2003–present)

The storyline of Transformers: Universe, mainly set following Beast Machines, sees characters from many assorted alternate continuities, including existing and new ones, encountering each other. The story was told in an unfinished comic book exclusive to the Official Transformers Collectors' Convention.

Live-action film franchise (2007–present)

In 2007, Michael Bay directed a live-action film based on Transformers, with Steven Spielberg serving as executive producer. It stars Shia LaBeouf, Josh Duhamel, Megan Fox, and Tyrese Gibson in the lead human cast while voice actors Peter Cullen and Hugo Weaving voice Optimus Prime and Megatron, respectively. Transformers received mixed to positive reviews and was a box office success. It is the forty-fifth highest-grossing film and the fifth highest-grossing film of 2007, grossing approximately $709 million worldwide. The film won four awards from the Visual Effects Society and was nominated for three Academy Awards, for Best Sound Editing, Best Sound Mixing, and Best Visual Effects. The performance of Shia LaBeouf was praised by Empire, and Peter Cullen's reprisal of Optimus Prime from the 1980s television series was well received by fans. A sequel, Transformers: Revenge of the Fallen, was released on June 24, 2009. It received mostly negative reviews, but was a commercial success and grossed more than its predecessor. A third film, Transformers: Dark of the Moon, was released on June 29, 2011, in 3-D and went on to gross over $1 billion, despite receiving mixed reviews. A fourth film, Transformers: Age of Extinction, was released on June 27, 2014, which also grossed over $1 billion, though it received generally negative reviews. A fifth film, Transformers: The Last Knight was released on June 21, 2017 to similarly negative reviews. Unlike its predecessors, the movie failed to recoup its costs for the studio. Bumblebee, directed by Laika's Travis Knight, was released on December 21, 2018, serving as a prequel to the first film, receiving positive reviews from critics. The movie was a box-office success. A sequel to Bumblebee, directed by Steven Caple Jr. and titled Transformers: Rise of the Beasts, was released on June 9, 2023 to mixed reviews from critics.

Transformers: Animated (2007–2010)

Transformers: Animated is a cartoon that was aired in early 2008 on Cartoon Network in the United States. Originally scheduled for late after 2007 under the title of Transformers: Heroes, Transformers Animated is set in 2050 Detroit (after crash landing 50 years earlier), when robots and humans live side by side. The Autobots come to Earth and assume superhero roles, battling evil humans, with the Decepticons having a smaller role until Megatron resurfaces. Main characters include Autobots Optimus Prime, Bumblebee, Bulkhead, Prowl, and Ratchet; Decepticons Megatron, Starscream, Blitzwing, Lugnut, and Blackarachnia; and humans Professor Sumdac and Sari Sumdac. Several characters that were in the original Transformers cartoon and 1986 animated movie, as well as characters only seen in comics and such, make special appearances and cameos throughout the show, with various voice actors (including Corey Burton, John Moschitta, Jr., Susan Blu, and Judd Nelson) reprising their roles.

Aligned Universe (2010–2021)

Hasbro, in an attempt to stop the wave of reboots that started in 2001, created the Aligned Universe, with the intent to unify every Transformers media into one continuity. The name of this continuity however, is not official; it was adopted by the fans after Hasbro referred to it as an "Aligned Continuity".

The toy lines derived from this continuity are Transformers: Generations, Transformers: Rescue Bots, and Transformers Go! The television series belonging to the Aligned Universe include Transformers: Prime (including its concluding film Prime Beast Hunters: Predacons Rising), the Rescue Bots TV series, its sequel Transformers: Rescue Bots Academy, the Go! anime adaptation, and the 2015 series Transformers: Robots in Disguise.

The video games that are part of this shared universe are Transformers: War for Cybertron (including its Nintendo DS version and the companion Transformers: Cybertron Adventures), Transformers: Fall of Cybertron, the Prime video game adaptation, and Transformers: Rise of the Dark Spark, that serves as a conclusion of the Cybertron series and crossover with the live-action film video game series.

Four novels set within the continuity have been published: Transformers: Exodus, Transformers: Exiles, Transformers: Retribution, and Transformers: The Covenant of Primus. The first three were published by Del Rey Books, while Covenant of Primus was published by 47North. In addition, IDW Publishing has published several comic books, including graphic novels, while Titan Magazines published Transformers Comic UK, a 20-issue series from 2007 to 2014.

The video games, novels, and television series contradict each other due to creative differences, miscommunications, constant team changes, and Aaron Archer being replaced with a different person that did not know the 354-page brand bible, "The Binder of Revelation".

Transformers: Prime Wars Trilogy (2016–2018)

In August 2016, Machinima and Hasbro co-produced an animated series named Combiner Wars, simultaneously published on the website Go90 and YouTube. This was followed by two further installments, Titans Return and Power of the Primes.

Transformers One (2024)

Upon the establishment of a writers' room for devising ideas regarding future Transformers films in 2015, the duo of Andrew Barrer and Gabriel Ferrari immediately conceived the concept of an animated prequel film depicting the beginnings of the Autobot-Decepticon war on Cybertron. The film is directed by Josh Cooley, who oversaw the story treatment by Barrer and Ferrari with additional script contributions by Eric Pearson. The film's narrative is centered on the respective origin stories of Optimus Prime and Megatron, chroncling their early friendship as Energon miners named Orion Pax and D-16, and the rift that causes their evolution into the respective leaders of the Autobots and Decepticons, beginning their long-standing conflict. Chris Hemsworth and Brian Tyree Henry lead the film's ensemble voice cast as Orion Pax and D-16 respectively, alongside Scarlett Johansson, Keegan-Michael Key, Jon Hamm and Laurence Fishburne. The film's score was composed by Brian Tyler, returning to the franchise after previously scoring Transformers: Prime. Transformers One released in September 2024, and received positive critical reception despite financially underperforming at the box office, grossing $124.2 million worldwide against a budget estimated to be between $75–147 million. Despite this, producer Lorenzo di Bonaventura expressed the desire for the film to launch a potential trilogy, confirming that the story was mapped out to illustrate a multi-film progression of the characters towards their traditional depictions in other media, such as the live-action films. By the film's release, di Bonaventura confirmed that the filmmakers were already outlining plans for a sequel, and that it would be produced if the film is considered successful.
