Transformers: Robots in Disguise is an anime series which has an associated toy line released in 2001 by Hasbro. The anime and toy line were originally released in Japan in 2000 by Takara as Transformers: Car Robots (トランスフォーマー・カーロボット).
Originally imported to the West as a "filler" line while Transformers: Armada was in production, Robots in Disguise brought the Autobot and Decepticon factions (and thus, the original concept of robots transforming into vehicles and other objects rather than organic-looking animals) back into the general public after five years of Beast Wars and Beast Machines lines. (Machine Wars, which was exclusive to Kay-Bee Toys branches, was a previous failed attempt at rejuvenating interest in both factions.) While it introduced many new figures, majority of the line consisted of repaints from Generation 1, Generation 2, Beast Wars/Beast Machines and Machine Wars.
