Multiverse

The Multiverse is a present theme in the Ultra Series. It is the setting in which all of the Ultra Series shows and series take place in.

History
The Multiverse was first implied in the Showa Era with Ultra Q and later, in the Heisei series with Ultraman Tiga. It was first truly confirmed in Ultraseven X and first shown in the movie, Ultraman Zero The Movie: Super Deciding Fight! The Belial Galactic Empire. Since then it has been openly acknowledged and is a part of some plot points. In the Ultra Galaxy Legend Gaiden: Ultraman Zero vs. Darklops Zero, an Alien Salome named Herodia and her henchmen attempted to gain access to the Multiverse and conquer it with an army of Imitation Ultra Brothers and Darklops Zero. Kaiser Belial later launched two separate attacks on the Land of Light, from another Universe. In Ultraman Saga, it was stated that the Ultramen had moved from not just protecting one Universe, but parts of the Multiverse. In Ultraman X, many Ultras from different universes visited X's universe either by accident or on purpose, but always with the same goal, to help defend it.
