Crossover Universe Wiki:Alternate Universe Crossovers

According to appendixes in Crossovers Volume 2 and Crossovers Expanded Volume 2, the following stories do not take place in the Crossover Universe due to either contradicting established CU continuity or being too parodic in nature.

However, there is enough evidence in CU lore to suggest that these crossovers exist within an interconnected multiverse and that cross-dimensional travel is prevalent.
