A Quick Tip by Madpenguin

Transformers is a popular^[1] Hasbro toy line centered on two factions of warring alien robots. In its 25-year history, the toyline has expanded to encompass comic books, cartoons, movies and more.

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 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 after 20th-Century. 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, the 2007 live-action film and some "Unicron Trilogy" etc.
