They already did most of the original regular cast in a 4-issue series called Transformers Universe, around the same time the movie came out. They even included all the new movie characters in the 4th issue. Most of the later profiles were intended for another series of Transformers Universe comics, but it was scrapped, so they put many of them at the end of the regular comics instead.One of them also includes some of the character profiles which originally appeared scattered throughout the old issues, but I'm a little puzzled over that because it's only a small number of characters (mainly Headmasters, Targetmasters etc). Why they'd include those characters and not more of the regular cast is strange to me. * shrugs *
