NOT A HOAX! NOT A DREAM!

In 2003, G.I. Joe license holder Devil's Due Press acquired a limited license from Hasbro to produce a crossover starring the Joes and the Transformers (whose main comic book rights lay at the time with Dreamwave). The resultant miniseries was successful enough to warrant three sequel series of varying lengths over the following three years, and I've reviewed all of them below.
