This Generation One Transformers Action Figure review is meant to serve as an in-depth informational review of the entire line of US released Transformers action figures from 1984 through 1990. There are plenty of lists out there that show all of the figures and all of their parts, so I don't feel that is necessary in this posting. What I feel is missing out there in the books and information on collecting Transformers Action Figures is a type of "Shopper's Companion" , so that's what this list is intended for. It serves as an informational review concentrating on typical flaws of each figure, and things you should keep in mind, or watch for while hunting down those new additions to your Transformers collection. I will not usually make a note about chrome wear or "yellowing", since basically any part that is chromed can have chrome wear and just about any figure can have "yellowing", the same goes with paint wear, or paint "chipping", unless it is unusually common with a particular figure. From time to time I will also include notes about foreign releases of the same figure. I have it split up series by series since all 360+ or so figures simply would not fit on one page.
