Transformers (トランスフォーマー, Toransufōmā) is an entertainment franchise co-produced between the Japanese Takara Tomy and American Hasbro toy companies. Initially developed as a brand by Hasbro and made up of renamed, rebranded transforming toys from Takara's Diaclone and Microman toylines, the franchise began in 1984 with the Transformers toy line, and centers on factions of transforming alien robots (often the Autobots and the Decepticons) in an endless struggle for dominance or eventual peace. In its decades-long history, the franchise has expanded to encompass comic books, animation, video games and films. The term "Generation 1" covers both the animated television series The Transformers and the comic book series of the same name, which are 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 2001 and IDW Publishing in 2005, also as a remastered series. There have been other incarnations of the story based on different toy lines during and after the 20th-Century. The first was the Robots in Disguise series, followed by three shows (Armada, Energon, and Cybertron) that constitute a single universe called the "Unicron Trilogy". A live-action film was also released in 2007, with a sequel in 2009, a second sequel in 2011, and a third in 2014. again distinct from previous incarnations, while the Transformers: Animated series merged concepts from the G1 story-arc, the 2007 live-action film and the "Unicron Trilogy". Transformers: Prime previously aired on The Hub. Although initially a separate and competing franchise started in 1983, Tonka's Gobots became the intellectual property of Hasbro after their buyout of Tonka in 1991. Subsequently, the universe depicted in the animated series Challenge of the GoBots and follow-up film GoBots: Battle of the Rock Lords was retroactively established as an alternate universe within the Transformers franchise.
