The Crossoverse is a fictional setting which combines the Stargate: SG-1, Teenage Mutant Ninja Turtles, Mighty Morphin’ Power Rangers, and Alien vs. Predator franchises into a single, unique multiverse continuity.  It was imagined in late February of 2011.

For now, Crossoverse is simply a setting in progress.  From here, it can still go many, many directions.  There are no solid plans for its future; it could be anything from a role-playing game setting to the source material for fan fiction.
