Transformers / G.I. Joe is not just another Transformers and G.I. Joe crossover, but rather a dark and war-torn recreation of the Transformers and G.I. Joe universes in tandem by writer John Ney Rieber and artist Jae Lee. In the twentieth century’s darkest year, a world at war will find itself caught in the middle of a titanic alien conflict that has lain dormant for the last four million years.
