The Transformers are a line of toys, comics, movies and television series that originated in the 1980s. The main characters are robots capable of transforming from vehicles or objects into giant robots, or vice versa.

The central concept of the Transformers is the war between two factions of extraterrestrial robots, the Autobots and the Decepticons, who clash for control of their home planet Cybertron and for the conquest of the universe. The Autobots are led by Optimus Prime, a just and brave leader, while the Decepticons are led by Megatron, an ambitious and ruthless tyrant.

The Transformers have become hugely popular due to their iconic characters, epic stories, and amazing transformations. They have been adapted into numerous media, including movies, animated series, video games, and comic books.
