Watch Transformers Cybertron Online

Set in 2025 A.D., Transformers Victory introduces Star Saber, the mightiest Autobot warrior and the greatest swordsman in the galaxy. Following the defeat of the Decepticons on Earth in the Masterforce War, the villains have begun aggressively attacking other planets in the universe. To counter this threat, the Autobots joined with many other civilizations and lifeforms (including Humanity) to form the Galactic Peace Alliance, with Star Saber as its leader. Seeking the energy necessary to free his massive Planet-Destroying Fortress from imprisonment in the Dark Nebula where Star Saber sealed it years ago, the Decepticons' new Emperor of Destruction, Deathsaurus (Dezarus), attacks Earth with his Dinoforce, prompting Star Saber and his team to set up residence on the planet.

Headmasters starts with Galvatron leading a new batch of Destrons to wage war on Cybertron, the Destron Headmasters. The Cybertrons are rescued by the arrival of the Cybertron Headmasters, led by Fortress (Cerebros, the head of Fortress Maximus). It is revealed that Fortress Maximus left Cybertron millions of years ago in search of energy, and have finally managed to come home. He explains that the Headmasters are from a planet called Master; the human-sized robots who live there built themselves Transformers-sized bodies. They can then transform themselves into the heads of the robots, and have now joined the Cybertron-Destron war.

Even though the Decepticons have been driven off Earth, a small team of Autobot Pretenders have remained behind, just in case. Led by Metalhawk ("Hawk" in his human identity), the Pretenders live among the humans, using their Pretender shells to assume human size and appearance. The Autobots' caution is rewarded: Decepticon Pretenders soon appear, led by a mysterious force called Devil Z. The Autobots and Decepticons soon build up their forces, recruiting humans to become Junior Headmasters and Godmasters (Powermasters).

Forced to abandon their home planet of Cybertron due to the threat of the Blackhole, Optimus Prime prepares to lead his autobot warriors to Earth. Just as they are leaving they are confronted by Vector Prime who warns Optimus Prime of the threat to the galaxy if the four Cyber Planet Keys are not gathered in time. However, Megatron has plans of his own for the universe. As they embark on the search, they land on new planets which are inhabited by different Transformer races as well as the Convoys who lead these planets.
