into equally small robots. There were initially six different Go-Bot styles produced, all of which were eventually given new colors and were assigned the names of G1 characters. The Cyberjets were small jet planes with missile launchers, and among the first Transformers to incorporate snap-together ball-and-socket articulated joints for the robot mode. There were three designs available in a total of six styles, three Autobots and three Decepticons. Two of the Autobot Cyberjets (Jetfire and Strafe) were decorated with G2 Decepticon symbols on their tail fins. A number of toys were planned for G2 for which prototypes were created, but were never sold as part of the G2 toy line. Some of these toys were revisited in later lines like Machine Wars and Robots in Disguise, in which the toys were offered under the Flipchangers and Spychangers assortments.

Produced early in the toy line, it features a few new Generation 2 characters, as well as many characters from the original series. The story concerned a form of Transformers, who called themselves Cybertronians, having evolved past Autobot or Decepticon.

In his search to discover the nature of the enemy, Optimus Prime went into the matrix, discovering that the Swarm was actually a by product of an early form of Transformer reproduction. In the UK, a five-issue Transformers: Generation 2 comic was published by Fleetway. While the first two issues featured exclusive UK material, the last three issues featured reprinted stories from the US comic. As a part of the Generation 2 line, several characters were given new forms, such as Megatron becoming a tank, due to the efforts of Cobra in Marvel's G.I. Joe: A Real American Hero #139. New characters appeared briefly towards the end of the series, including the Rotor Force, Laser Rods, and the Combat Hero edition of Optimus Prime. In Japan, both TV Magazine story pages and mini-comics packaged with toys told a different G2 story. Set in the animated series' timeline (specifically after the end of Battlestars: Return of Convoy and therefore Operation Combination), the story tells of a true time of peace between Autobots and Decepticons, known as the Cybertron Alliance, until human soldiers accidentally kill one of Megatron's most loyal
