Alternate universes

Alternate Universes are universes of nature similar to our own, with differences that vary from subtle to extreme. Our/Futurama's universe does not have an official name, though it was called "Universe A" by the Planet Express crew, and "Universe Gamma" by Yivo. "Gamma" implies it is third in a series. Presumably, Yivo considers shkler own "Universe Alpha" with "Universe Beta" heretofore unknown. Parallel universes can be accessed via certain portals, including Parallel Universe Boxes and Anomalies.

Known Universes
Below is a list of parallel universes in the order they appear. There are at least 1730 universes.

Names appearing in italic are non-official names (i.e. their name is never actually mentioned).


 * Cowboy Universe
 * The first alternate universe shown, it was created simultaneously by the Big Bang. In this universe, everybody dresses as cowboys.  Before the events of "The Farnsworth Parabox", it was thought the only other existing alternate universe. It is possible that this is the only universe which was extradimensionally adjacent to our own, thus limiting access to the others. Through various means, these extradimensional gaps have been bridged.


 * Pocket Dimension Universe
 * Where the Infosphere and the Brain Spawn are now. This universe is white with various hues. This implies it may be the reverse of our own, if only chromatically.


 * Universe 1
 * The main difference in this Universe is that coin flips have opposite results to those in our own universe. The Parallel Universe Boxes here are blue, and instead of the sky being blue with clouds, and at night sky being black, the sky is like a rainbow. At night the colors are darker.


 * Icy Universe.
 * Women Universe.
 * Octopus Universe.
 * Universe 25
 * Here, none of the inhabitants appear to have eyes, though they are not unfamiliar with the concept of sight. (e.g., when asked if they saw anything, they replied in the negative, rather than question what "see" means) The Parallel Universe Boxes here are white.


 * Universe 1729
 * Inhabitants are Bobbleheads who say impolite things and speaking seems to set them in motion. The Parallel Universe Boxes here are pink.


 * Universe 31
 * Inhabitants shown are robots. It is possible (though not confirmed) that robots would likewise be human. The Parallel Universe Boxes here are green.


 * Universe XVII
 * A universe where society hasn't moved past that of Ancient Rome, though they apparently have science advanced enough to create their own Parallel Universe Boxes, which are purple.


 * Leprechaun Universe.
 * Pirate Universe.
 * Universe 420
 * Inhabitants are hippies and smoke marijuana. They have a shortage of boxes, which are orange.


 * Yivo's Universe
 * The universe where Yivo lives by shklerself (and later with Colleen). Interestingly, while all the other parallel universes mimic our universe in some fashion, this universe does not. It is entirely different, and according to Yivo, this universe is older than ours. Our universe is toxic to its inhabitants, but the reverse does not seem to be true.


 * Cornwood
 * An alternative reality, created by Bender's imagination. Possibly gone as they failed their quest.


 * Ironic Universe
 * A universe where everything is ironic, which is used for the scripts of The Scary Door
