Transformers are alien robots of a popular Hasbro toy line and its spin-offs.
Transformers: G1, includes both the animated television series The Transformers and the Marvel Comics comic-book series of the same name, which is further divided into Japanese and British spin-offs, respectively. Sequels followed, such as the Generation 2 comic book and Beast Wars TV series which became its own mini-universe. Generation 1 characters underwent two reboots with Dreamwave in 2002 and IDW Publishing in 2006. There have been other incarnations of the story based on different toy lines during the 2000s. The first was the Robots in Disguise series, followed by three shows that consist of the "Unicron Trilogy" (consisting of Armada, Energon, and Cybertron). A live-action film was also released in 2007 and a sequel has since been released in 2009, again distinct from previous incarnations, while the Transformers Animated series merged concepts from the G1 story-arc and the 2007 live-action film.
