The Autobots are the main protagonists in the fictional continuities of the Transformers multimedia franchise, and are depicted in a collection of various toys, cartoons, films, graphic novels, and paperback books first introduced in 1984. The Autobots, led by Optimus Prime, are opposed by the Decepticons, the main antagonists in the universe of the Transformers, headed by Megatron.    Both Autobots and Decepticons have "sparks", which function as souls and contain their minds and personality. They can transform into machines, vehicles and other familiar mechanical objects, as well as mimic organic lifeforms (Dinobots). Autobots typically transform into cars, trucks and other road vehicles; some exceptions transform into aircraft, military vehicles, communication devices, weapons, or robotic animals. These Autobots are often grouped into special "teams" that have the suffix "-bot" at the end, such as in Dinobot (Decepticon groups' names end in "-con").
In Japan, the Autobots are called "Cybertrons" (サイバトロン, Saibatoron)  except in the film series, Transformers Animated , and Transformers: Prime , where they are referred to as Autobots (オートボット, Ōtobotto). In Italy, they are called "Autorobots". The Autobot insignia is also sometimes referred to as an "Autobrand" in issue #14 of the Marvel Comics series. The descendants of the Autobots, the Maximals from Transformers: Beast Wars, are also known as Cybertrons in Japan.
In the Michael Bay live action films, as well as in the CGI-animated series Transformers: Prime , the title Autobots is explained to be the short version of the title Autonomous Robotic Organisms.
In all Transformers stories, the Autobots and their adversaries, the Decepticons, originated on the planet Cybertron. The planet is almost always depicted as a purely metallic body.  The capital of Cybertron is Iacon. In later issues of the Marvel comic line, Cybertron is shown to have weather, such as rain.
