Cybertronian: The Unofficial Transformers Recognition Guide was a series of unofficial guidebooks published by Antarctic Press between 2001-2002, documenting the American Transformers toy line. Over the course of seven volumes, it covered every American Generation One, Generation 2 and Machine Wars toy, as well as the first year of the Beast Wars toy line. Their high-quality imagery made the guidebooks an ideal photo-reference and artists and colorists at Dreamwave comics would rely heavily on copies of Cybertronian, along with certain Studio Ox character models, as an artistic reference.
