Transformers, also using the cover titles Transformers and Action Force, Transformers and Visionaries and Transformers and G.I. Joe the Action Force at various stages during its run, was a comic produced in the United Kingdom by the British division of Marvel Comics between 1984 and 1992 primarily featuring the Transformers. It was printed fortnightly for its first and last year and weekly for the years in between. It had a long relationship with Action Force, first as a vehicle for promoting the Marvel UK Action Force comic and then, after that title folded, as a home for reprints of the Marvel US G.I. Joe A Real American Hero.
