The Ghostbusters IDW Timeline Canon includes the events in the movies Ghostbusters and Ghostbusters II, select elements of the realistic and stylistic versions of Ghostbusters: The Video Game, and Tobin's Spirit Guide from Insight Editions; which lead off to the IDW take on the "Prime" Ghostbusters. The canon introduced multiple dimensions to the Ghostbusters Universe. This canon uses the multiple dimensions to allow other timelines to co-exist within it.
List of Dimension[]
This lists media used that formed the backdrop for a given dimension. Some elements might be slightly changed for inclusion so to not derail the main given narrative. While previously, some dimensions were part of the same canon, it is noted that a given crew was taken from a slightly different dimension from the other, even though they seem to be from the same canon in a different time.
