Multiverse

A multiverse is a collection of universes which feature in Power Rangers and Super Sentai. The game Power Rangers Legacy Wars establishes that there are infact multiple multiverses. This point of view is also taken by Marvel Comics through the concept of the Omniverse, the ultimate collection of every single version of reality imaginable.

Power Rangers
As cemented in Dimensions in Danger, the vast majority of Power Rangers TV series take place in the same universe. Two exceptions are RPM World, the post-apocalyptic setting of Power Rangers RPM, and Dino Charge World, a world whose history was altered to allow the dinosaurs to survive as seen in Power Rangers Dino Charge. The constant of the seperate universes, known as "Ranger Worlds" or "Ranger Dimensions", is that they are all home to teams of Rangers.

The reimagined Mighty Morphin Power Rangers comic series by Boom! Studios takes place in a seperate reality from the original series to the point of establishing a new multiverse. Lord Drakkon, the counterpart of Tommy Oliver from the parallel World of the Coinless, serves as instigator the Shattered Grid event which sees the Morphin Grid, in a bid to compensate for a critical alteration to the timeline, seperate the histories of future Ranger teams into seperate universes.

The story of the video game Power Rangers Legacy Wars features a crossover between Power Rangers (2017), a reboot film taking place in its own reality, with the TV series' characters as well as concepts from the Boom! Studios comics. A later update to the game stretches the story as potentially affecting "all multiverses" as the universe of  is visited.

Super Sentai
Through numerous crossovers with other Toei tokusatsu franchises such as Kamen Rider and Metal Heroes, Super Sentai is linked to a .

Generally, the vast majority of Super Sentai series are treated as taking place in a common world. A sole exception is Uchu Sentai Kyuranger, which is established as taking place in a seperate universe.

Seperate from the mainstream Super Sentai, the metafictional Hikonin Sentai Akibaranger features three distinct dimensions; Reality, home to the Akibarangers where Super Sentai exists as a TV show, the Delusion World, and Hatte's World, a dimension home to the writer Saburo Hatte.
