Earth-S is one of the infinite number of divergent realities that made up the pre-Crisis on Infinite Earths Multiverse.

World War II

  • In Earth-S's version of the months leading up to WWII, the Axis Powers included: Austria, Bulgaria, Croatia, Germany, Hungary, Italy, Japan, Romania, Sermia, and others.
  • After America's entry into WWII during December 1941, the fictional evil nations seemingly disappeared.

Forgotten Catastrophes

In addition to the large number of disasters, terrorist attacks, wartime setbacks, and large-scale super-crimes that were prevented by the super heroes and masked adventurers of this parallel world, there were some catastrophes that actually happened, then never were mentioned again. These included:

  • Mexico was invaded by a subterranean civilization, in 1940.[1]
  • The Federal States Building in Washington D.C. was destroyed with a bomb, in the spring of 1941.[2]
  • New York City was attacked by a column of armored tanks, with massive destruction and civilian casualties, in the summer of 1941.[3]
  • The Shuker Hotel skyscraper, in one big city, was destroyed with multiple pre-planted charges, by a gang of Nazi agents, in the summer of 1941.[4]

End of History

During the Crisis on Infinite Earths, Earth-S was effectively merged with Earth-One, Earth-Two, Earth-Four, and Earth-X to form one composite universe. It was restored to the Multiverse by the events of Convergence.

A significant number of American cities existed uniquely on Earth-S, and many of these had no direct counterparts on "nearby" parallel worlds such as Earth-One or Earth-Two. Examples include:


A significant number of modern nations existed uniquely on Earth-S, and many of these had no direct counterparts on "nearby" parallel worlds such as Earth-One or Earth-Two. Examples include:

  • Europe:
    • Adolfuss, briefly a dictatorship.[5]
    • Ecalpon, a war-torn hell-hole.[6]
    • Grafstan, a monarchy striving to become a democracy [7]
    • Mentonia, a monarchy until at least 1941.[8]
    • Slavonia in Central Europe, where peasants wear lederhosen, nobles wear capes, and dueling is legal.[9]
    • Sylvania, an ancient mountain kingdom, long-time location of the legendary "Silver Slippers" [10]
    • Yugovania, a small nation wracked by severe postwar food shortages [11]
  • South America:
    • Rinaldo, a republic. Rinaldo's embassy in the USA was blown up in 1941.[12]

Secret Kingdoms and Lost Civilizations

A significant number of alien outposts, secret kingdoms, and lost civilizations, some populated and some not, existed uniquely on Earth-S, and many of these had no direct counterparts on "nearby" parallel worlds such as Earth-One or Earth-Two. Examples include:

  • In the African jungle, 20 days travel inland from the Gold Coast, beyond the River of Skulls, is an unexplored region in which prehistoric giant rhinos and mammoths, monstrously large snakes, and gigantic frogs all live, alongside 15-foot-tall gorillas and 12-foot-tall men.[13] In this area, sparrows grow as big as turkeys, and eagles grow as big as dive bombers. Some modern African elephants, not mammoths, also inhabit the region, and grow to be much larger than ordinary African elephants. More significantly, the legendary Elephants' Graveyard is in one remote part of this unexplored area.[14]
  • In the Brazilian jungle, 15 days march inland from Rio de Janeiro, near the Great Mountain, a Forgotten World with populations of many long-extinct plant and animal species, discovered by Bill Watkins in 1948.[15]
  • In the Wartz Forest of Middle Europe, the Fortress of Freedom, founded in 1450 by Kroza, the leader of the Kroza Rebellion. This stone fortress sat unmolested for 500 years, until 1950, when another peasant rebellion overthrew the tyrannical rule of Kroza VIII.[16]
  • In the South Pacific, until at least the early 1940s, there was an isolated Land of the Amazons.[17]
  • In the South Pacific, according to legend, and a map in the possession of Captain O'Casey of the "Starfish", the Lost City of Kazar, and all its riches, could be found.[18]


Several of the planets in the Earth-S universe are very different from their counterparts in other "nearby" universes such as Earth-Two or Earth-One. Examples include:

  • Earth-S-Twin:
    • In 1949, a near-identical copy of planet Earth was discovered, by Professor Jimson, using a special infra-red telescope. This planet was nearly invisible, and on a collision course with Earth-S, until Captain Marvel placed it in orbit around a distant star. This planet and its people had a history that very closely paralleled that of Earth-S, with a few notable exceptions:
      • The North Pole was first explored in the late 1940s, by Sir Struthers, rather than in 1909, by Admiral Byrd.
      • Woolly Mammoths roamed the Arctic, but dogs and cats were extinct.
      • Antarctica was populated, and spaceships were in widespread use for commercial travel.
      • George Washington was currently the president of America, and Julius Caesar currently ruled Rome.
      • Neanderthal men, Vikings, Roman soldiers, and 1949-style civilians all lived in the same city.
      • Firearms had not been invented.[19]
  • Mars:
    • In the late 1940s, a group of Martians attempted to conquer Earth. They covered the western half of the United States with a green substance that appeared to be mold or a bacterial colony, but was actually solidified energy.[20]
  • Saturn:
    • In 1940 Captain Marvel discovered an enslaved population of humans on Saturn, and freed them from an invasion of enslaving aliens. After this the Saturnian humans began the long hard task of rebuilding their civilization.
  • Venus:
    • In Earth-S history, the planet Venus was explored and colonized by Dr. Thaddeus Bodog Sivana, some time before 1940.
      • Sivana established a spaceship base and a palace, and crowned his daughter, Beautia, the Empress of Venus.[21]
      • Sivana once exported six rocketshipsful of Venusian wildlife, including bulletproof sabretooth tigers, prehistoric elephants, giant horned crocosaurs, and the gorillion (a hybrid gorilla-lion centaur), to Earth, where he displayed them in a traveling circus.[22]
    • Venus is also the birthplace of international criminal mastermind Mister Mind, and is home to several species of brainless night-crawlers, slugs, and maggots.[23]

The Squadron of Justice


The properties of matter, laws of physics, and principles of chemistry were very different on Earth-S from those of our own world, or of "nearby" parallel universes such as Earth-Two or the Quality Universe. For example, the weather on Earth-S is controlled by a cantankerous entity known only as the Weatherman.[24]

  • 1950, Sivana's Heavy Gravity device,[46]

Unorthodox Engineering

Many devices, gadgets, and vehicles were built on Earth-S that could never have been built or made to work on our own world.


  • 1940, Drown's Mechanosaurus (giant underwater robot dinosaur),[47]

Sensors, Computers, Communications
