Who are the opposites of the Autobots?
Autobot
Autobots are a team of sentient mechanical self-configuring modular robotic lifeforms from the planet Cybertron led by Optimus Prime, and the main protagonists in the universe of the Transformers, a collection of various toys, cartoons, movies, graphic novels, and paperback books first introduced in 1984. The "Heroic Autobots" are opposed by the Evil Decepticons.[1][2][3] Both Autobots and Decepticons are humanoid robots that can transform into machines, vehicles and other familiar mechanical objects, as well as mimic organic lifeforms (Dinobots). Autobots typically transform into regular cars, trucks, or other road vehicles (auto</i>mobiles) but some few are aircraft, military vehicles, communication devices, weapons, and even robotic animals. These Autobots are often grouped into special "teams" that have the suffix "-bot" at the end, such as in Dino<i data-parsoid='{"dsr":[2847,2854,2,2]}'>bot (Decepticon groups' names end in "-con").
Dinobots
The Dinobots appeared with yet another origin in the second "G.I. Joe vs the Transformers" series from Devil's Due Publishing. In 2004, the Dinobots were among the Autobots under the leadership of Optimus Prime, who attempted to take the planet Cybertron back from the Decepticon tyrant Shockwave. An accident sent the Dinobots back in time, and they landed on the planet Earth, where they were reformatted in the forms of Earth dinosaurs. A group of humans (which included Gung-Ho, Dusty and a Cobra Viper) brought the new Dinobots back to Cybertron, where they helped overcome Shockwave.
