The following is a list of episodes in the Transformers series, Transformers: Cybertron. It chronicles the adventures of the Autobots, as they battle the Decepticons and attempt to claim the four Cyber Planet Keys.
The series uses four pieces of theme music. For the first twenty-seven episodes of the series "Call You - Kimi to Boku no Mirai [The Future of You and I]" by Shinji Kakijima is used for the opening theme and "Itsumo" by Tomoka Issei is used for the ending theme. The remaining episodes use "Ignition!" by CHINO for the opening theme and "Growing Up" by Shinji Kakijima for the Ending theme. In the English dub of the series, all of the original ending themes are removed, with the song "Transformers: Cybertron Theme" by Paul Oakenfold used for both the opening and ending in all episodes.
The stage is set for the final confrontation between Scourge and Optimus Prime. The Autobot team arrives on the Jungle Planet, with Override representing the Speed Planet, and Lori representing Earth. The Decepticons plan a 'welcome party' for the Autobots, which only delays the inevitable confrontation. Later, Optimus Prime and Leobreaker team up to defeat Scourge. Scourge asks Optimus to kill him as he was the loser, but Optimus refuses, claiming that Scourge was a worthy opponent.
