Pilot miniseries The three-part pilot
miniseries (retroactively titled "More than Meets the Eye") first aired in the United States in September 1984. The story follows
Optimus Prime's heroic
Autobots and
Megatron's evil
Decepticons as they leave their metallic homeworld of Cybertron to search for new sources of energy to revitalize their war efforts, only to crash-land on
Earth, where they remain entombed and offline for 4 million years. Awakening in the year of 1984, the Decepticons set about pillaging the energy sources of Earth, while the Autobots—aided by human father and son duo Sparkplug and Spike Witwicky—attempt to protect the new world on which they find themselves. The miniseries concludes with the Decepticons believed dead after their space cruiser is sent plunging into the ocean depths, while the Autobots prepare to return to Cybertron.
Season 1 The 13-episode first season, commissioned and produced before the pilot miniseries aired, was broadcast between October and December on Saturday mornings. Story-edited at Marvel Productions by Bryce Malek and Dick Robbins, the season begins with the revelation that the Decepticons have survived the events of the pilot and follows them as they set about constructing a "space bridge" to teleport resources back to Cybertron. A loose story arc centered on this technology spans the season, culminating in "The Ultimate Doom", a three-part episode in which the Decepticons teleport Cybertron itself into Earth's orbit. The paraplegic computer expert Chip Chase joins Spike and Sparkplug as a new human ally for the Autobots. The season also introduced several new characters from the upcoming 1985 product line in advance of their toys' release including
Skyfire, the Dinobots, the
Insecticons, and the first "combiner" team, the
Constructicons, who are able to merge into a giant robot, Devastator, whose introduction was set alongside a climactic one-on-one duel between Optimus Prime and Megatron that served as a part of the season finale.
Season 2 Forty-nine further episodes were commissioned for the show's second season in 1985, bringing the total up to the "magic number" of 65 required to move the series into weekday
broadcast syndication. Compared to the first season, Season 2's stories are more episodic, with many of them able to air in whatever order networks chose. Episodes would often spotlight individual characters or groups of characters as a means of promoting their toys and later in the season, the lore of the series would be expanded on as the history of Cybertron and origin of Optimus Prime were discovered and significant cartoon-original characters like
Alpha Trion and the first female Transformer characters were introduced. A new recurring human cast member was also added in the form of Spike's girlfriend Carly. Partway into the season, the remainder of the 1985 product line was introduced, mostly through the two-part episode "Dinobot Island." These new characters, like the first year cast, were largely derived from Takara's
Diaclone and
Micro Change lines, including new Autobot car and mini-vehicles and Decepticon jets and the giant Autobot sentinel
Omega Supreme and Decepticon "Triple-Changers"
Astrotrain and Blitzwing. To expand the line, however, Hasbro also licensed several toys from other companies, including Takara's Japanese competitor, Bandai. Legal complications that arose from incorporating the first of these, Skyfire, into the first season resulted in the character quickly being phased out early in Season 2 and meant that none of the other Bandai-derived characters featured in the series. Toward the end of the season, the first 1986 product was introduced into the series: the
Aerialbots,
Stunticons,
Protectobots and
Combaticons, four combiner teams based on an unmade
Diaclone line that was aborted in Japan in favor of importing the Transformers toy line itself. To promote these new toys even further in Japanese markets, a single Japanese-exclusive episode,
Transformers: Scramble City, was released direct-to-video in spring of 1986.
The Movie The gap between seasons two and three was bridged by
The Transformers: The Movie, which was released to theaters in the summer of 1986. Set 20 years after the second season, in the year 2005, the film featured the deaths of many characters, including Optimus Prime, clearing away all the discontinued products from the 1984 and 1985 toy lines and introducing a new cast of the characters designed for the film, who were then made into toys for the 1986 range. Young Autobot Hot Rod used the power of the Autobot talisman known as the
Matrix of Leadership to become the new Autobot leader
Rodimus Prime and defeated the world-eating robot planet
Unicron who recreates Megatron into
Galvatron while Skywarp, Thundercracker, Shrapnel, Kickback, and Bombshell are reformed as Cyclonus, Scourge and the Sweeps.
Season 3 Season 3 picks up where the movie leaves off, with the Autobots now in control of Cybertron once more, working to restore their homeworld and serving as peacemakers for worlds all across the galaxy. The Decepticons, meanwhile, are in exile on the ruined world of Chaar, led now by
Galvatron. Interconnected episodes, running plot threads and small story arcs became more common in the series, including the return of
Starscream (following his death in the movie) as a ghost, frequent battles between the giant Autobot and Decepticon cities of
Metroplex and
Trypticon and the threat to both sides posed by the alien
Quintessons, introduced in the movie and revealed in the season's premiere miniseries "Five Faces of Darkness" to be the true creators of the Transformers. This season also saw the debut of three new combiners: the Predacons, the Terrorcons, and the Technobots. This season saw story-editing duties transfer from Marvel Productions to Sunbow, overseen by
Flint Dille,
Marv Wolfman and
Steve Gerber. Animation for around half the season was provided by producer
Nelson Shin's animation studio AKOM, creating a different "look" for the show that encompassed its opening sequence and commercial bumpers. The death of Optimus Prime proved a controversial move and did not sit well with the viewing audience, resulting in a letter-writing campaign that ultimately compelled Hasbro to resurrect the Autobot leader in a two-part season finale called "
The Return of Optimus Prime", which aired in March 1987. Optimus Prime was revived with help from a Quintesson during the threat of the Hate Plague.
Season 4 The fourth season, consisting of a three-part finale miniseries named "The Rebirth", was broadcast in November 1987. Written by regular series writer
David Wise, the Autobots and Decepticons encounter the alien world of Nebulos, where they bond with the native Nebulans to become
Headmasters and
Targetmasters. The Nebulons led by the evil Lord Zarak were able to transform the animal Decepticons with Scourge and Cyclonus into Headmasters while some of their weapons were transformed into Targetmasters. While Lord Zarak was able to become the Headmaster to his creation Scorponok, Spike Witwicky was able to operate the Headmaster unit so that he can control Fortress Maximus to fight Scorponok. The miniseries concludes with the successful restoration of Cybertron, but the Decepticon threat not yet quashed as Galvatron and Lord Zarak argue over who will rule the galaxy upon their victory over the Autobots.
Later developments The Transformers did not disappear from American airwaves, as a fifth season aired in 1988. It consisted of reruns of 15 episodes from the original series, along with
The Transformers: The Movie edited into five episodes. This season featured a new title sequence using footage from previous episodes, the movie, and toy commercials as well as all new framing scenes featuring a human boy named Tommy Kennedy (portrayed by actor Jason Jansen) and a stop-motion/machine prop Optimus Prime puppet (operated by
Sesame Street veteran
Martin P. Robinson). From 1993 to 1995, select episodes of the series were rebroadcast under the title
Transformers: Generation 2. The stories were presented as though they were historical recordings displayed by the "Cybernet Space Cube", which added computer-generated borders and scene-transitions to the original animation. The story was later continued in Transformers: Generation 2: Redux, a Botcon magazine that is set 22 years after the events of the final episode where the first generation of the Autobots led by Optimus Prime pursue Galvatron and Zarak into deep space and a new generation of Autobots and Decepticons are introduced. ==Supplemental sequences==
