   * The Monitor is born on Oa's moon after its creation. He spends his life in silent meditation, learning the secrets of the universe. Meanwhile, the Anti-Monitor is born on the moon of Qward after its creation in the antimatter universe. The Anti-Monitor grows powerful and easily takes control of Qward, creating an army of Thunderers, then formed an elite personal guard from the Thunderers called the Shadow Demons. The Anti-Monitor spreads his reign of terror throughout the antimatter universe. //Note: The text claims that the Anti-Monitor and the Monitor were created as a result of Krona's actions, but this can only mean that Krona's actions affected the distant past in addition to the present.// [Crisis on Infinite Earths #7]   * The Monitor is born on Oa's moon after its creation.

As expert builders of robots and androids, their crowning achievement is Eterno, a nearly 50-foot-tall half-robot, half-android constructed to live forever, energized by cosmic radiation, and given the complete knowledge of the Xan in his artificial brain. Although Eterno was incredibly wise and powerful, he planned to conquer Earth for himself. Before he could do so, a cloud of space gas drifted to Earth that the Xan knew could kill them off. Eterno traveled to the earth's core to find absorbium, the only element that could combat the space gas, but the absorbium caused Eterno to become paralyzed for nearly a billion years until he is temporarily freed in the year 1977 AD by the Superman Revenge Squad. Meanwhile, the Xan become extinct from the space gas. //Note: The Xan are said to have lived about a billion years ago, but their civilization probably arose after the Demons Three are defeated by the Timeless Ones. Possibly the Timeless Ones invited the Xan to Earth in order to ensure that the Demons Three would remain captive.// ["Eterno the Immortal," Action Comics #343 (November, 1966)]

   * On Krypton, where science was just beginning to mature, a nuclear disaster wrecks a whole town and kills thousands, prompting the government to forbid all scientific research. As a result of outlawing science, civilization on Krypton is stunted for many thousands of years.

-  * On Earth, during a time when the sun is red (possibly because of a cloud of space gas altering the sun's rays), a group of colonists from the star system of Vruun led by Jhor Lal establish a colony that they call Atlantis, fleeing from the cruel tyrants who rule their world. A few members of the Legion of Super-Heroes (Brainiac 5, Star Boy, Chameleon Boy, Light Lass, and Phantom Girl) arrive via time travel from the 30th century A.D. and help them complete the city of Atlantis, the first human city on Earth. //Note: This date is never firmly established except as "millions of years ago," but the the date can be established as one million years before 43,000 BC, since Atlantis has been in existence for one million years by then. It's likely that the Earth's sun was artificially turned red for a time, possibly by the space gas that killed off the Xan, since scientific data suggests that by this time the Earth's sun was nearly as bright as it is today, and was definitely the same hue.// ["The War Between Krypton and Earth," Adventure Comics #333 (June, 1965)]+  * On Earth, during a time when the sun is red (possibly because of a cloud of space gas altering the sun's rays), a group of colonists from the star system of Vruun led by Jhor Lal establish a colony that they call Atlantis, fleeing from the cruel tyrants who rule their world.

   * On Krypton, a scientist named Zat-El, hiding in the Jewel Mountains along with a small number of Kryptonians who practice science, which is at this time outlawed, builds a space ark. A few members of the Legion of Super-Heroes (Superboy, Saturn Girl, Lightning Lad, Element Lad, and Colossal Boy), arrive from the 30th century and assist the construction of the space ark. The Kryptonians, accompanied by the Legionnaires from the future, leave Krypton with supplies and a group of giant, dinosaur-like reptiles. They arrive on prehistoric Earth and establish a colony on what is now Western North America. Having believed that Earth was uninhabited by any intelligent species, they are surprised to discover that a colony from Vruun has already been established as Atlantis.

   * War is soon declared between the Atlanteans and the Kryptonians, with each group of Legionnaires taking opposing sides in what is intended to be a bloodless war, until a few Kryptonians are accidentally killed by Atlanteans. Meanwhile, Brainiac 5 discovers that the element xenon in Earth's atmosphere is poisonous to the Atlanteans and will kill them all in time, but if the Atlanteans are genetically modified to become water-breathers and live beneath the ocean, they can be saved. Mon-El arrives from the 30th century in time to stop an atomic missile launched by the Kryptonian colony from destroying Atlantis. The Legionnaires end the war between the Kryptonians and the Atlanteans by genetically modifying the Atlanteans into the original mer-folk (half-human, half-fish), then sinking the city of Atlantis into the ocean.

-  * Time traveling from 1977 AD, Superman is stranded for some days during a relatively brief period when the sun is red, and he consequently has no super-powers. After being mistaken for a god but showing weakness, he is attacked by a strong caveman named Guarr (who looks like Abraham Lincoln) and is beaten by him. A cave-girl named Virra nurses Superman back to health, and Superman later finds water for her tribe and helps them overcome Guarr and his tribe.
