Earth kids enter a conflict between two factions of Transformers.

The Transformers is the first animated television series in the Transformers franchise. The series depicts a war among giant robots that can transform into vehicles and other objects.

Two spaceships, one manned by benevolent Maximals, the other by evil Predacons, crash-land on a pre-humanoid planet while en route to Earth. Their crews assume indigenous animal forms to protect themselves from an overabundance of natural energy, transforming into robots to do battle. Thus, the Beast Wars have begun...

Beast Wars II refers to the 1998 Japanese Transformers television animated series, and the movie and toyline that resulted from it. The series was preceded by Beast Wars, and was followed by Beast Wars Neo.

The series has a much lighter tone and is aimed more towards children, whereas the more accessible Beast Wars was intended for a wider age range. The series also uses conventional animation rather than CGI like Beast Wars: Transformers. With the exceptions of the faction leaders, all of the characters within the series are either re-molds or re-colors of earlier Beast Wars figures or Generation 2/Machine Wars figures.

In addition to the 43 episodes, there is also a 50-minute movie, Beast Wars II: Lio Convoy's Close Call!, which takes place sometime between episodes 32 and 38.

Transformers: Cybertron, known in Japan originally as Transformers: Galaxy Force, is the 2005-2007 Transformers toy line and animated series, another co-production between Hasbro and Takara. It was aired in Japan as a separate rebooted transformers series, though in America, the English dub was presented as a sequel to the previous series, Transformers: Armada and Transformers: Energon by adding dialogue and reusing a number of screens to link elements of the Armada and Energon series to the show, giving the impression that it is a sequel. In the anime, all of the Transformers are computer-generated, while the humans and backgrounds are rendered in traditional 2D animation. It is the last series in the Transformers franchise to be produced in Japan.

Transformers: Choujin Masterforce aired on Japanese television from 1988 to 1989. Taking place after Transformers: Headmasters, it is the story of how Metalhawk and his small team of Autobots must protect Earth from the mysterious Devil Z and his Decepticon forces. Humans play many prominent roles in Masterforce, from the Decepticon husband-wife team of Giga and Mega to the Autobot's Junior Headmasters and the reluctantly-recruited Ginrai. Masterforce is often considered second only to Transformers: Victory as a fan favorite.

While Megatron takes drastic measures to save the Decepticons, the Autobots fight to save all of Cybertron from both on the planet and aboard the Ark.

The show takes place ten years after the finale of Armada, opening in an age of peace on Cybertron and Earth which is destined not to last long. Energon pits the Autobots against an array of villains: the reborn Megatron , the barely functional Unicron, and the mysterious Alpha Q and his Terrorcon minions.

The evil Decepticons have appeared in Detroit. With the all powerful Allspark, Megatron can use it to turn all of Earth's robots into Decepticons. However, Optimus Prime and his Autobots arrive and plan to stop Megatron and his evil plan in Transformers Animated.

After the end of the Beast Wars, the Maximals awaken on their home planet of Cybertron and are chased by mindless Vehicons created by Megatron. The Maximals must free the planet from Megatron and restore it to its real way of living.

Fire Convoy fights to protect the Earth from the tyrannical Gigatron and his Destrongers. Aiding him in his quest are the three Car Robo Brothers, Cybertron computer hologram Ai, and human friend Yuki Onishi.

Transformers: Victory is an anime series produced by Toei Animation. It is a Japanese-produced spin-off of the well-known original Transformers cartoon, and the final complete animated series from the original "Generation 1" era.

Roll out with Optimus Prime, Bumblebee, Arcee, Ratchet, Bulkhead, and the rest of the heroic Autobots as they battle the evil Decepticons. Now that big bad Megatron has returned with a mysterious and dangerous element, Team Prime must prepare for an epic battle.

Following on The Return of Optimus Prime (and in place of The Rebirth), The Headmasters is the first Japanese-exclusive Transformers franchise.

Years after the events of Predacons Rising, Bumblebee is summoned back to Earth to battle several of Cybertron's most wanted Decepticons that escaped from a crashed prison ship and assembles a team of young Autobots that includes Sideswipe (a rebel "bad boy bot"), Strongarm (an Elite Guard cadet), Grimlock (a bombastic Dinobot), and Fixit (a hyperactive Mini-Con with faulty wiring).

In a galaxy far away, there is a kid without innate ability to practice internal techniques. So, in order to gain the respect of his father, he resolutely chooses to follow the more difficult and painful path of practicing external techniques. As the years go by, he grows up, but what really changes his life is a mysterious meteoric crystal stone – the Meteoric Tear. This stone fuses with the young man’s body unnoticed, and he seems to undergo drastic transformations as a result. After that, everything is changed. Eventually his father knows that the son for whom he hasn’t really shown a lot of consideration possesses astonishing abilities. And there’s a lot more to come.

The Malto Family’s world turns upside down when the Terrans, the first Earthborn Transformers robots, spark to life. The Terrans will forge an alliance between the human Malto family and the legendary Autobots, uniting them in a shared mission.

A team of specialized Autobots not quite ready for prime-time battles against the Decepticons is given a vital mission by Optimus Prime. The goal for the Bots is to learn about mankind and how to help others to find out what it really means to be a hero.

On their dying planet, the Autobots and Decepticons battle fiercely for control of the AllSpark in the Transformers universe's origin story.

An evil race of transforming robots known as the Destronger make their appearance known by invading a world exposition in New York and abducting Professor Onishi, a renowned scientist. The professor's son Yuuki befriends Fire Convoy and the heroic Cybertron forces, who will stop at nothing to rescue the professor and protect Earth from the wrath of Gigatron and his Destronger henchmen.
