Dark Spark War is a multiversal war which happened prior to the Ultraman Ginga tv series that raged between the side of good and the forces of evil, as represented by the competitors, the Ultramen, monster and aliens seen in various universes. It is now known that this Universe is an alternate reality to the Showa Universe and the Ultras seen here may in fact be alternate versions of their Showa (and other Universes) counterparts.
