Publication history.
Following the bankruptcy of Dreamwave Productions in 2005, IDW picked up the "Transformers" comic book license and hired veteran writer Simon Furman to craft a rebooted continuity based on the toy line, similar to what Marvel Comics did through Ultimate Marvel. In May 2008, IDW obtained the "G.I. Joe" comic book license from Devil's Due Publishing. Over the years, both comics participated in several crossover events, like "Infestation" and "Infestation 2". In 2016, IDW gained the rights of "Rom", "Micronauts", "Action Man" and "M.A.S.K." from other publishers. That same year, IDW announced the Hasbro Reconstruction campaign, in order to converge those brands in the same continuity, starting with the crossover event "Revolution". In 2017, IDW gained the rights of ', with most of its characters debuting after the crossover event "First Strike". In April 2018, IDW announced the HCBU would conclude with the limited series ' in November 2018.
In-continuity canon.
IDW has never established a shared continuity between its own "Transformers" and "G.I. Joe" comics, even during the crossover event "Infestation", when they both exist in separate universes, with other licensed franchises. While "The Transformers" has only participated in "Infestation", the miniseries "", also set in its own alternate timeline, has participated in "Infestation 2". On the other side, "G.I. Joe" participated in both events.
Other brands exist within the HCBU too, e.g. "Jem", "Clue" and "Army Ants", but they didn't crossover during "Revolution", "First Strike" or "Transformers: Unicron" due to reasons of tone. IDW's versions of "My Little Pony", "Dungeons & Dragons", "", "Stretch Armstrong" and "Go-Bots" exist "outside" of this universe entirely.
