Timeline of Earth-4 (1930s to 1950s)

1931

  • The first atomic rocket ship from Mars lands secretly on Earth near Helena, Montana. By 1948, over the next 17 years, 411 Martian ships secretly land on Earth, leaving behind over 40,000 Martians, who look identical to humans. Helena, Montana, is their landing base. Note: This information was related in 1948 by a Martian calling himself Jason DeKoven, who may have been lying or exaggerating. Although at least two Martians are shown to have the strength of ten men, others may have no enhanced strength; certainly human-identical Martians depicted in other stories have no added strength. Still others may be affected by Earth diseases; it is possible that of the 40,000 Martians that landed on Earth over 17 years, most of them may have died from disease, since they lacked the immunity to fight it. Sometime after the failed 1948 invasion of Earth, most if not all of the remaining Martians are returned to Mars or otherwise die on Earth. It is also possible that Martian interference on Earth, whether intentional or otherwise, may have resulted in the age of super-powered men and women, beginning in 1939 with the debut of Wonder Man.

1933

  • The Feeder, a sentient pocket of parasitic energy that feeds on fear, lands on Earth and inhabits an infant named Gantry Babbitt, who grows up to be first a juvenile delinquent and then a television preacher. [E-Man (First) #7]

1936

April, 1936

  • April 19: William Donalley, an electric company repairman, is electrocuted by high tension wires. Although he is apparently considered dead for three and a half hours, he comes back to life with vastly increased intelligence and various mental abilities. [“Death Did a Double,” Unusual Tales #25 (December, 1960)]

February, 1936

  • The Phantom XXI, real name Paul Walker, begins protecting the jungles of Bangalla as his ancestors have done for centuries. Note: The Earth-4 Phantom is not exactly the same as the Phantom who appeared in the Phantom comic strip. For example, Diana Palmer was born much later and became the wife of the 1960s/1970s Phantom. Also, this Phantom is named Paul instead of Kit, a name he gives his son. [The Phantom (King Features Syndicate newspaper comic strip)]

1937

July, 1937

  • July 7: The Second Sino-Japanese War breaks out.
  • Reporters Jack Flynn and Joan Joyce, lost in an unknown region of Tibet while en route to cover the war in China, meet the immortal Shangra, the seventh son of the seventh son of Shangra the Great, king of Tibet many centuries ago. Shangra is a master of magic, supernatural ability, and sorcery. Flynn marries Shangra's great-great-great granddaughter Lonna and becomes the new king of Shangraland, learning everything that Shangra knows about sorcery. [Crash Comics #1-5]

1938

  • The Phantom XXI has an adventure that takes him to Casablanca, where he meets Rick Blaine. Note: Some characters from the films Casablanca (1942) and the Maltese Falcon (1941) appear in this story. [The Phantom (Charlton) #70]
  • John Ordway, a research scientist afflicted with albinism, invents a serum that causes invisibility, and he uses it to commit burglary and murder. He dies before his brother Charles is able to administer the serum that reverses his invisibility. Charles goes mad and is put in an insane asylum for at least 10 years. [“The Man Who Vanished,” The Mysterious Traveler (1943 Mutual Broadcasting System radio series)]

The Heroic Age

1939

March, 1939

  • Fred Carson becomes the super-powered mystery man known as Wonder Man, has a single case. [Wonder Comics #1]
  • Wonder Man ends the devastating civil war in Tatonia by stopping the corrupt Gen. Attila, one of the leaders of the rebel army. Note: Since the Spanish Civil War also ended at this time (officially ending on April 1, 1939), it is possible that Tatonia is either Spain itself, a province in Spain, or most likely a small country next to Spain. Gen. Attila is probably affiliated with Franco of Spain. [Wonder Comics #1]
  • Patty O'Day, news reporter and photographer, begins adventures. [Wonder Comics #1]
  • Dr. Fung, master sleuth of the Orient, begins adventures, with ally Dan Barrister. [Wonder Comics #1]
  • K-51 (originally called K-5 and whose real name is Ken Flynn), agent in the Secret Service, begins adventures. Note: K-51's name is never revealed in his original series. [Wonder Comics #1]
  • Richard G. "Gang-Buster" Robinson (also called Mob Buster Robinson) begins adventures. [Wonder Comics #1]
  • Spark Stevens, sailor, begins adventures, with ally Chuck Lawton. [Wonder Comics #1]

April, 1939

  • Yarko the Great, a magical mystery man considered the mightiest magician of all time, has his first public case. He defeats the second most powerful magician of the age, the evil Shaddiba, whom he had previously met in India. Note: Yarko the Great has been active since 1937 and has helped law enforcement several times already. Since the character Mr. Mystic, created by Will Eisner to act as a backup series for the Spirit Section, is actually a retooled version of Yarko the Great, also created by Eisner, Mr. Mystic can be considered the Earth-X parallel of Yarko the Great. [Wonder Comics #2]
  • K-51 meets Claire Conos, alias agent Z-19 of the Secret Service. [Wonder Comics #2]

May, 1939

  • Gary Preston becomes the super-powered mystery man known as the Flame. [Wonderworld Comics #11 (origin); Wonderworld Comics #3]
  • Yarko the Great battles Death and the Devil. [Wonderworld Comics #3]
  • K-51 battles recurring criminal foe Lin Sun, a Mongolian princess, for the first time. Although Lin Sun appears to die, she actually fakes her death. Note: K-51 and Z-19 (Claire Conos) become engaged sometime between this story and the next. [Wonderworld Comics #3]

June, 1939

  • Walter Green, a former soldier whose wife was murdered by criminals, becomes the mystery-man and outlaw known as the Green Mask, a modern-day Robin Hood based in New York City. Only “News” Blake Doakes of the Daily Globe is aware of his true identity. In his first case, the Green Mask smashes an insurance scam ring and captures its leader, a corrupt politician named Cyrus Boomer. Note: It is evident that the non-powered, tall, and lanky Green Mask from Mystery Men #1-12 is a different individual than the more muscular, super-powered Michael Shelby, who first appears as the second Green Mask a year later. Walter Green is the father of Johnny Green, the third Green Mask, who is introduced as the son of the original Green Mask. Johnny is ten years old in 1939. [Mystery Men Comics #1]
  • Chen Chang, criminal mastermind who is accompanied by the sultry River Lily, begins his criminal adventures, opposed by the heroic Richard Kendall. [Mystery Men Comics #1]
  • Wing Turner, air detective, begins adventures. [Mystery Men Comics #1]
  • Zanzibar, magician mystery man, begins adventures. [Mystery Men Comics #1]
  • Inspector Bancroft of Scotland Yard begins adventures. [Mystery Men Comics #1]
  • Dan Garret, a rookie policeman, becomes the mystery man known as the Blue Beetle, originally a non-powered crime-fighter in a blue business suit, hat, and mask. His only confidante is Dr. Abe Franz, a druggist who keeps a special room in the back of his store for the Blue Beetle to operate from. In his first case, he avenges his policeman father who was killed. As a police officer himself, Dan is partnered with his father's old partner, Mike Mannigan. [Mystery Men Comics #5] [Blue Beetle #1 (origin); Mystery Men Comics #1]
  • D-13 (Richard Anthony), secret agent, begins adventures. [Mystery Men Comics #1]
  • Captain Denny Scott of the Bengal Lancers begins adventures. [Mystery Men Comics #1]
  • Lt. Drake of Naval Intelligence begins adventures. [Mystery Men Comics #1]

July, 1939

  • The Blue Beetle begins wearing a short-sleeved chainmail costume devised by Dr. Abe Franz that makes him bulletproof. [Mystery Men Comics #2]
  • For weeks, mysterious radio broadcasts announce the impending arrival of Stardust the Super-Wizard, an extraterrestrial crime fighter who has vast powers and has battled organized crime on other planets and will do the same on Earth. Upon Stardust's arrival, he prevents the attempted assassination of President Franklin Delano Roosevelt, stops a bombing raid on Washington, D.C., and rounds up all the foreign spies responsible for this attack, delivering them to the FBI. Note: Stardust's arrival on Earth is heralded by radio messages and newspaper headlines that speak of his successful battles against crime on other planets. However, since it is highly unlikely that interplanetary rumors would spread so easily, Stardust is likely the individual responsible for the radio broadcasts announcing his arrival, which the newspapers reported on. The general public probably does not believe Stardust is an extraterrestrial. This story takes place sometime before the outbreak of World War II in September, 1939. Stardust probably has a specific mission on Earth to battle the effects of criminal extraterrestrial interference, since most of his enemies all use super-science far more advanced than remotely possible by human standards. This would explain why he does not simply stop all crime and war on Earth, since most crime and war merely results from the human condition. [Fantastic Comics #1]
  • Dr. Harry Kane, a brilliant young government chemist on a special assignment working on a formula for a new steel compound, is murdered by enemy agents who steal the formula, leaving his wife and assistant Shannon Kane a widow. Finding a formula for a spider-web fluid in his records, which Harry never found a use for, Shannon develops the formula and finds that when shot into the air the fluid becomes a thin, adhesive filament. Later inventing a set of special bracelets to contain the fluid and release it as needed, Shannon eventually uses it to become a mystery woman called the Spider Queen. Note: The Spider Queen begins fighting crime sometime before her official debut two years later in July, 1941. The enemy agents are never identified; it is possible that these are agents of the Soviet Union rather than Nazi Germany, explaining why she hates communism. [Eagle #2 (September, 1941)]

August, 1939

  • K-51 seemingly averts the coming war in Europe, apparently stopping the plans of Hitler (who supposedly murdered Mussolini and is supposedly killed himself) and convincing Stalin not to cooperate with Hitler. Unfortunately, immediately after these events Stalin signs a secret non-aggression pact with Hitler, planning the division of Poland, and the deaths of both Mussolini and Hitler turn out to be false. Note: In this story, the three European leaders who began World War II are named as follows: Adolf Hitler is called Rudolph Morga, Benito Mussolini is Carlo Riano, and Joseph Stalin is called Diableff. This story as presented is either fictionalized or leaves much of the actual story out, since both Mussolini (Riano) and Hitler (Morga) die and war is averted, which doesn't happen in real history. Probably doubles of Hitler and Mussolini, and possibly also Stalin, are used to create confusion for K-51. [Wonderworld Comics #9]
  • A powerful man known only as Rip-the-Blood, who secretly controls the governments of several leading nations and owns many munitions factories, makes plans to start a new world war. He stages a fake attack by a Japanese bomber on President Franklin Delano Roosevelt's fishing yacht and has him abducted. Stardust the Super-Wizard once again rescues President Roosevelt, returning him to the White House, thus preventing the outbreak of war with Japan. Stardust then captures Rip-the-Blood and destroys one of his munitions factories and imprisons his conspirators on an interplanetary jail, then kills him. Afterwards, Stardust leaves for the planet Mars to stop the world war there. Note: This story takes place before the September, 1939, invasion of Poland that began World War II. It is probably connected in some way with K-51's battle against Hitler and Mussolini. Rip-the-Blood's true name is not known (possibly a name such as Rip Van Bludd), but he is likely one of the influential financial powers that hold much control over governments and is not known by the public as anything more than a businessman. While Stardust is away on Mars, World War II begins in earnest, and he does not return until December, 1939, too late to prevent the war. This story mentions the Interplanetary Guardian of the Peace, who is connected with the Interplanetary Police first mentioned in Fantastic Comics #4. [Fantastic Comics #2]
  • Stardust the Super-Wizard arrives on the planet Mars, where he battles individuals trying to start a world war there for the next four months. One of those individuals is an Earthman named Dr. Martinious, who traveled to Mars in his own rocketship sometime earlier and began making himself the warlord of Mars by stirring up Martian nations against each other. [Fantastic Comics #6]

September, 1939

  • September 1: Germany invades Poland, sparking World War II.
  • David "Yank" Wilson, a super-spy known as secret agent Q-4, has his first known case when Nome, Alaska, is attacked by the nation of North Polaria – led by the dictator Raxola – beginning a short but heated war between the United States and North Polaria. Wilson is appointed stratosphere commander in the air attack. While North Polaria has a slight advantage at the beginning of the war, it is soon sorely outmatched, and Raxola and his troops surrender within hours. Note: This story probably takes place shortly after the invasion of Poland. North Polaria on Earth-4 is likely an unrecognized nation existing in the northern countries (much like Kurdistan exists in parts of Turkey, Iraq, and Iran) only in the early 20th century, and which is funded and armed by the Soviet Union as a defense against an attack from the U.S. over the Arctic Circle. Raxola likely takes it upon himself to invade the U.S. without consulting the Soviets. North Polaria as a nation and a political idea ceases to be after this moment. [Fantastic Comics #1]
  • Captain Savage, sea rover, begins adventures on the high seas. [Mystery Men Comics #4 (November, 1939)]
  • The Blue Beetle now wears his familiar long-sleeved chainmail costume devised by Dr. Abe Franz that provides almost full-body protection from bullets. [Mystery Men Comics #4 (November, 1939)]
  • The Green Mask gains a paralyzer-gun invented by a criminal scientist named Nicoli, alias the Professor. [Mystery Men Comics #4 (November, 1939)]

October, 1939

  • During the 1939 World's Fair in New York City, scientist Montague Dexter and his wife leave on a rocketship of his own invention, the destination: Mars. The public believes it is merely a publicity stunt but wonder about it when the couple is never seen again. Note: Montague Dexter is the father of Rex Dexter of Mars, who becomes an interplanetary explorer in the year 2000 of an alternate timeline. [Mystery Men Comics #1]
  • Sam, a super-strong, modern-day descendant of the Biblical hero Samson, becomes the mystery man known as Samson and has his first public case as a mystery man. [Fantastic Comics #1]
  • Captain Kidd, pilot, begins adventures. [Fantastic Comics #1]
  • Flip Falcon (originally Flick Falcon), scientist and explorer, invents a fourth dimension machine and uses it to travel through the fourth dimension to explore various destinations, including other planets, other dimensions, the future, and the past. [Fantastic Comics #1]
  • Lin Sun, recurring criminal foe of K-51, has her last recorded battle with K-51. [Wonderworld Comics #8]

November, 1939

  • Inspector Bancroft's last case. [Mystery Men Comics #6]
  • Mob Buster Robinson's last case. [Wonderworld Comics #9]
  • Dr. Fung battles recurring criminal foes Karno the Chessman and his henchmen (several costumed, winged henchmen who use jet-packs to fly; one is dubbed the Moth by the press). [Wonderworld Comics #9]

December, 1939

  • Bill Powers (sometimes called Ted Powers) becomes the super-powered mystery man known as the Eagle. [Science Comics #1]
  • Jim Andrews gains electrical super-powers and becomes the mystery man known as Electro. [Science Comics #1]
  • Marga, the Panther Woman, is infused with panther blood and begins adventures alongside aviator Ted Grant in the jungles of Africa. [Science Comics #1]
  • Navy Jones, able to breathe water and equipped with a special submarine, begins adventures in the deep sea, protecting the Undersea Kingdom populated by the fish-men (also called the gill-men) and ruled by Princess Coral and her father, the king of the sea. Note: The Undersea Kingdom is also known as the Hidden Empire as seen in Doomsday +1 #4; although the events of Doomsday +1 take place in an alternate future, the Hidden Empire has existed for many centuries by that time and exists in the main timeline of Earth-4. Other underwater races include the chalk-white-skinned amphibians, who created the gill-men as well as their enemies, the shark-men. [Science Comics #1]
  • At the end of the four-month-long Martian world war, Dr. Martinious has become the warlord of Mars. [Fantastic Comics #6]
  • Stardust the Super-Wizard battles the Demon, a criminal scientist who believes the world is overpopulated and plans to destroy every large city in the world to reduce the population. The Demon creates a huge tidal wave that destroys an ocean liner, killing all 2000 passengers. Stardust kills the Demon and saves New York City from being destroyed by the tidal wave. Note: Stardust the Super-Wizard has been on Mars stopping the world war there since August, 1939, and is thus too late to prevent the world war on Earth. It is possible that he is bound by strict rules concerning which criminals he can stop (such as those possessing super-scientific weapons that can immediately change the balance of power), explaining why he doesn't simply invade Germany and kill Hitler. [Fantastic Comics #3]
  • Recurring criminal foe Karno the Chessman with his henchman, the Moth (who dies), battle Dr. Fung for the last time. [Wonderworld Comics #10]
  • The Crime Syndicate is formed when gangsters Frankie Ciconi of New York City, Rod Riley of Chicago, “Shive” Parker of St. Louis, and “Goldie” Gates of San Francisco join forces, beginning a nationwide crime wave. They invite the Green Mask, thinking he's a criminal leader thanks to his outlaw reputation, but instead the Green Mask captures the Syndicate leaders when they try to destroy the S.S. Britannica. [“The Crime Syndicate,” Mystery Men Comics #7 (February, 1940)]

1940

  • Doctor Doom, criminal scientist and mass-murderer, travels back through time to 1940 from the mid-21st century and attempts to take his revenge on Earth by causing widespread destruction and death, thereby changing history. He is pursued from the 21st century by Jan Swift and Wanda, who establish cover identities as reporters for the Daily Star and manage to stop his every scheme, including an early invasion from Venus. Note: In all but the last two (or possibly three) stories, Doom exists in the future, while in the final stories he exists in the present, as do Jan and Wanda; only time travel can explain why exact doubles of all three could exist in the past. [Science Comics #8, Green Mask #4, Big 3 #1]

January, 1940

  • Denny Scott's last case. [Mystery Men Comics #8]
  • Electro changes his mystery man name to Dynamo. [Science Comics #2]
  • A giant unnamed mad scientist based in the Gobi Desert in Mongolia uses a chemical substance to create a volcano in the middle of Lake Michigan, but Stardust the Super-Wizard prevents it from destroying Chicago, Illinois. Stardust then delivers the giant to the Interplanetary Police. Note: This is the first mention of the Interplanetary Police, which is not pictured. [Fantastic Comics #4]

February, 1940

  • The wealthy Jim Blake, endowed by a famous biologist with the power of flight and tremendous energy to overcome almost all obstacles, creates a winged flying costume to control his flight and becomes the mystery man known as the Moth. [Mystery Men Comics #9]
  • Grant Farrel is given super-powers by the god Thor and begins adventures as the mystery man called Thor. [Weird Comics #1]
  • The Sorceress of Zoom, sometimes a villainess, sometimes a heroine, begins adventures in Zoom, a traveling city in the clouds. Note: The city of Zoom is probably originally from a magical dimension, such as the Land of the Nightshades. [Weird Comics #1]
  • Dr. Mortal, criminal scientist, begins adventures. [Weird Comics #1]
  • The Voodoo Man, witch doctor, begins adventures, opposed by young Dr. Bob Warren. [Weird Comics #1]
  • The Bird Man, gifted with the ability to fly, begins adventures on the plains. [Weird Comics #1]
  • A group of super-scientific criminals known as the Miracle Men led by a criminal scientist called Wolf-Eye abduct the wealthiest men in the United States using invisible vacuum tubes, then demand outrageous ransom sums for each of them. The FBI decides not to cooperate, and Stardust the Super-Wizard arrives just in time to save several FBI agents from being destroyed by Wolf-Eye's death-ray. Stardust then prevents a powerful artificial tornado created by Wolf-Eye from destroying New York City. Stardust captures Wolf-Eye and the Miracle Men and delivers them to the FBI, at the same time returning the abducted wealthy men to their homes. [Fantastic Comics #5]

March, 1940

  • Flip Falcon stops the plan of his recurring foe, the fallen angel Lucifer, to destroy the Earth. [Fantastic Comics #6]
  • March 15: Dr. Martinious, the warlord of Mars, uses Martian technology to invade the Earth during the Ides of March. The Brain Men of Mars, working for Martinious, begin an invasion of Earth by bombarding it with meteorites containing disease germs and Martian insects. Stardust the Super-Wizard delivers crucial chemicals to scientists on Earth to combat the disease germs and insects, then attacks the Martian laboratory of the Brain Men. The governments of the world, including both the Allies and the Axis, unite to combat the Martian invasion of microbes using Stardust's chemicals. Stardust destroys the stronghold of Dr. Martinious, presumably also killing him and the Brain Men with him. Note: Since his lifeless body is not pictured, it is possible that Dr. Martinious survives his stronghold's destruction. [Fantastic Comics #6]
  • March 21: Victor Sage is born in Crown City.

April, 1940

  • A criminal gang led by “Gyp” Clipp uses an anti-solar ray to begin canceling Earth's gravity, using other rays to cancel the effect of the ray on everything except human bodies, in order to take the Earth for themselves. While Clipp kills the other members of his gang in a greedy attempt to have everything for himself, Stardust the Super-Wizard cancels the effects of the anti-solar ray before it causes much more than a slight weightlessness in Earth's population. Stardust then captures Clipp and imprisons him in an interplanetary prison called the Floating Prison of Eternal Ice, which has the strange effect of preserving the criminal's frozen body while enabling his mind to remain active so that he can ponder his crimes. Note: It is obvious that the anti-solar ray pictured in this story could not have been invented by Clipp and probably not by any Earthman, but is instead an extraterrestrial weapon given to criminals on Earth to do mischief. This story erroneously pictures the entire population of Earth floating into the upper atmosphere and being returned to their exact places on Earth by Stardust. In fact, what happens is that Stardust stops the anti-solar ray before it is able to do much more than cause the Earth's population to feel a sense of weightlessness, but gravity is never entirely canceled out, and the population does not float into the upper atmosphere. [Fantastic Comics #7]

  • Inspector William Blake of Scotland Yard begins adventures. Note: Blake (born circa 1881) was the boy named Billy, who was the protege of Sherlock Holmes in the 1890s (see the 1939 film The Adventures of Sherlock Holmes), and he is recognized as Holmes' successor at Scotland Yard. [Whirlwind Comics #1]

Stardust then battles and defeats the Emerald Men, then relocates Asperus to another solar system that is uninhabited. Note: The Emerald Men use the same type of transmitting suits later used by Space Smith in the 22nd century. [Fantastic Comics #8]

June, 1940

  • Michael Shelby and his father, Senator Dan Shelby, are gunned down by agents of the Grim Circle; the senator dies, but his son barely clings to life. Prof. Martin Lascomb uses his experimental vita-ray machine to revive the injured Michael, but an accident causes him to be struck by thousands of volts of electricity at the same time, granting him the super-powers of strength, vitality, and limited flight. After meeting Walter Green, who retires as the original Green Mask, Shelby becomes the Green Mask II. An orphaned boy named Don Mason is injured and also healed by vita-rays, which grant him vitality but doesn't give him super-powers; he becomes Domino the Miracle Boy, the Green Mask II's teenaged crime-fighting partner, who uses a boomerang as his primary weapon. Together, the two bring down the Grim Circle in their first case together. Note: Michael Shelby's vita-ray-induced super-powers begin to wane a few months after he gains them; it's likely that repeated vita-ray treatments are necessary to give him powers again. Don's last name is never revealed in the comics, so we have given him the last name of Mason in honor of Hollis Mason (Nite Owl) of Watchmen, who like Don Mason wore a domino mask and wrote a memoir about his heroic second life. It should also be noted that Don's surname is not Tracy, since that is the surname of Olivia Tracy, who is Michael Shelby's love interest. Domino is first referred to as Don in Green Mask #6. [Green Mask #1]
  • The Blue Beetle begins using Vitamin 2X, created by Dr. Abe Franz, which originally grants the Blue Beetle super-energy but later enables him to gain full-fledged super-powers. [Mystery Men Comics #13]
  • Jim Blake changes his costumed name from the Moth to the Lynx. He adopts an orphaned boy named Phil, who becomes Blackie the Mystery Boy, the Lynx's teenaged crime-fighting partner. [Mystery Men Comics #13]
  • The Eagle loses his wings and gains flight power through his cape. [Science Comics #7]
  • Caius Martius, an ancient Roman, awakens from a 2,200-year sleep and becomes the mystery man known as the Dart, taking the name Caius Martius Wheeler in his everyday identity as high school history teacher. Andy Barlow becomes Ace the Amazing Boy, the Dart's teenaged crime-fighting partner, nicknamed the Amazing Boy. [Weird Comics #5]
  • Thor's last case. [Weird Comics #5]
  • The Sorceress of Zoom attacks the city of Nagpur, India, but the aging Hindu sorcerer Rana Bhat (Rani-Bey) and his son Loknath Bhat (Lani-Bey) successfully fend off her attack. Note: Since Bey is a Turkish-based title and a Muslim surname, it would be unusual to say the least for a Hindu family to bear this name; therefore, we have assumed that the names “Rani-Bey” and “Lani-Bey” are incorrect transliterations of similar-sounding Hindu names. [Weird Comics #5]
  • Jag, a jaguar cub, begins adventures. [Cyclone Comics #3]
  • In deep space, Stardust the Super-Wizard battles the interplanetary space warlord Moloka, destroying his fleet and preventing him from invading the solar system. [Fantastic Comics #9]

  • Scoop Hanlon's last appearance. [Whirlwind Comics #3]
  • An extraterrestrial criminal scientist called the Super Fiend of the Lost Planet uses a thermal ray spore to cause the Martian moon of Phobos to burn, killing its entire population of Martian colonists in the process. The Super Fiend then sends the burning Phobos toward Earth to set it afire as well. Stardust the Super-Wizard saves Earth, stops the fires on Phobos, and returns Phobos to its orbit around Mars. Stardust battles the Super Fiend and leaves him on the ruined moon of Phobos, alone with the charred bodies of all the Martians he murdered. Note: In the story, the entire population of Mars is killed by fire, while the planet itself is sent to strike Earth. Since other stories show the Martian population still thriving, there must be another explanation. We theorize that it was the largest of Mars' two moons, Phobos, that was populated by Martian colonists and that was sent to Earth. [Fantastic Comics #10]

August, 1940

  • A huge criminal gang led by “Skullface” Kurd carries out a planned terror assault on New York City, causing explosions in the subway system and dropping bombs on the streets and bridges using planes. The gang then begins slaughtering the police and rescue teams, but Stardust the Super-Wizard prevents the slaughter of any more, disintegrating the bombers and bringing the entire NYPD out of harm's reach. Stardust then captures the entire “Skullface” Kurd gang and takes them all to a distant planet full of gold and precious gems, where the gravity is too great for them to do anything with this mineral wealth. Note: It is probable that patrolman Dan Garret (the Blue Beetle) is among the NYPD officers saved by Stardust. Possibly the first team-up of the Big Three occurs as a result of this story. Although this is not explained in the story, “Skullface” Kurd is most likely acting under the direction of a foreign power, such as Germany or Japan, which is somehow able to supply Kurd with the resources required for his assault.

Stardust the Super-Wizard stops the invasion and captures Kaos, then rescues a woman abducted by the vultures who was intended to be the Venusian's empress.

Stardust causes the bombers to destroy the line of super-tanks, then destroy themselves by diving into the ocean. Stardust then transforms the lesser leaders of the Fifth Column into ice, which melts away, and the greater leaders into monster rats, which are chased into the river by Stardust, who is in the form of a panther. All except the transformed Yew Bee (who has his human head on a rat's body) are drowned, and Stardust delivers Yew Bee to the FBI for questioning.

He also learns that Nazi Germany has been approached by emissaries from Mars known as the Sky-Demons, who send a fleet of rocketships to assist Germany's planned invasion of the Americas. Stardust creates a decoy Earth created from Moon vapor, then causes the Earth to become invisible from space. Meanwhile, the Axis is able to quickly conquer the nations of South America with the assistance of the Fifth Column. As the Martian fleet arrives at the decoy Earth, it gives the signal to the Axis invaders to begin its invasion of North America. But Stardust uses rays to cause all members of the Fifth Column to become paralyzed and then transports them all through the air into outer space and into the decoy vapor Earth. The arriving Martian fleet destroys the vapor Earth with disintegration bombs, then heads back to Mars after discovering they had been tricked. Stardust then selects the loyal youth of the United States and forms an army of boys called the Sixth Column, temporarily granting them some of his powers. The Sixth Column attacks the Axis armies that are preparing to invade Panama and sends every soldier back to his own country. The boys form a youth civilian defense organization called the Stardust Sixth Column Club, with chapters all over the United States. [Fantastic Comics #14]

The Sixth Column members telepathically track down members of the Fifth Column, who they learn are conspiring with racketeers to take over the country. They also learn that the Fifth Column is preparing to assist with another attempted invasion of the United States, using magnets that will draw powerful shells fired from Europe to crucial defense points and big industrial plants throughout the country. Stardust equips the leaders of the Sixth Column with powerful ray belts, which the boys use to destroy most of the incoming shells. After one shell accidentally destroys an ocean liner, Stardust causes all the other shells to destroy the approaching fleet of warplanes. While the Sixth Column rounds up as many Fifth Column members it can find, Stardust kills the Fifth Column leaders and then disintegrates all the remaining members. [Fantastic Comics #15]

  • A gangster named “Master-Mind” De Structo attempts to kill every person of power and authority in the United States at the same time, using vials containing a ray that destroys all oxygen in its vicinity. De Structo remotely activates the vials, causing every American leader to begin to suffocate. Stardust the Super-Wizard destroys De Structo's controls and counteracts the vials' rays, saving the lives of President Franklin Delano Roosevelt and all members of Congress as well as anyone else affected. Stardust captures the fleeing De Structo, transforming him into a bodiless head, and brings him into an area of deep space known as the Space Pocket of Living Death, where he delivers De Structo to the Headless Headhunter, which absorbs him into its body. Returning to Earth, Stardust gathers De Structo's gang and transforms them all into one person, then shoots him into space. [Big 3 #2]
  • In his last known case on Earth, Stardust the Super-Wizard uncovers a plot by a criminal gang led by “Slant-Eye” to rob the U.S. gold depository at Fort Knox in Kentucky. The gang uses a fleet of planes to bomb Fort Knox and attack it with an army of parachutists. After using explosives to gain access to the gold bullions, the criminal army is paralyzed by Stardust, who leaves the army in the hands of the U.S. military but takes “Slant-Eye” with him. Stardust brings “Slant-Eye” back to the criminal's island headquarters, where he torments him before giving him over to a gigantic yellow octopus-like creature called the golden octopus. Work on rebuilding Fort Knox begins immediately. Note: It is likely that Stardust the Super-Wizard left the vicinity of Earth for several decades, becoming occupied in interstellar cases on several other planets without returning to Earth until 1985. His reason for leaving the solar system at this time is probably that he has stopped all the major menaces to Earth's peace caused by extraterrestrial technology and interference.

Note: Johnny's father is the original Green Mask, alias Walter Green, who quit his mystery-man career to serve in the military, where he is active in the Pacific Theater of War. Walter Green is the original, unpowered, unnamed Green Mask who appeared in Mystery Men Comics #1-12 and is not to be confused with Michael Shelby, the second Green Mask. The general public is likely unaware that there was more than one Green Mask. Johnny transforms into the Green Mask, complete with super-powers, whenever he becomes agitated. The reason behind this is likely mystical in nature rather than pseudo-scientific. [Green Mask #10]

Note: This story may actually take place some months earlier, just before Dan Garret leaves his intelligence agent job to rejoin the police force as a so-called rookie policeman.

  • During the “Threat from Saturn” adventure, the Blue Beetle battles the evil Saturnia and Gloat, two criminals exiled from Saturn in a meteor who have the ability to possess human bodies (much like Jericho of Earth-1's Teen Titans) and plan to set themselves up on Earth as the king and queen of evil. At one point, Gloat manages to possess the Blue Beetle himself and goes on a super-powered rampage in order to discredit him as a hero, but Blue Beetle forces him out before Gloat is able to commit mass murder using his body. After the conclusion of the case, Saturnia and Gloat make no further appearances. Note: This story ended at Chapter 6, with Joan Mason kidnapped by Gloat and Saturnia, who fled into one of several underground tunnels.

Note: Tiger's real name of Tanaka is revealed in the post-Crisis L.A.W. series, and it is the same in Earth-4's continuity as well. This name is obviously inspired from Tiger Tanaka, an ally of James Bond – inspired by real-life Japanese author Torao “Tiger” Saito – who appears in the novel You Only Live Twice and the film based on it, where he is played by actor Tetsuro Tamba. In tribute to that actor, we use the name Tetsuro as Tiger's first name. [Judomaster #93]

  • Rocket Kelly, Whacky, and Sue Andrews travel to the planet Selura. There, with the help of a dwarf ally named Sabio, they liberate the planet Selura from an Earthman named Dr. Malik, a scientist. Contacting Earth, they receive a reply stating that Kelly is the official Earth ambassador to Selura. On Earth, a rocketship capable of interplanetary travel called the New Yorker is built and launched into space, where it is magnetically pulled to Selura by Kelly. From this point on, Rocket Kelly becomes an interplanetary explorer and hero, traveling in a rocketship. Note: Although it is not evident, the building of the New Yorker and the communications with Kelly on Selura are actually completely classified and top secret, known only to the highest levels. The public merely believes that a science fiction movie is being filmed. Probably the New Yorker was built using the same classified technology as that of Dr. Hans Zarkov, ally of Flash Gordon. It is never explained how Dr. Malik first traveled to Selura, but presumably he also had access to Zarkov's technology and may even have been a collaborator. [Everybody's Comics #1, The Bouncer #10]

Judomaster is presumed to die in the war, but in reality he is transported through time because of the Crisis on Infinite Earths to the year 1985, where he remains. His teenaged partner Tiger (Tetsuro Tanaka) retires. Note: In 1953, eight years after Judomaster's disappearance, a grown-up Tetsuro Tanaka becomes the Tiger, Japan's first costumed crime-fighter. In 1958, Tiger trains a 14-year-old Eve Eden in martial arts; she grows up to become Nightshade in 1966. Tiger himself becomes Judomaster II for a brief period in 1965 and trains another young man to become Tiger II. Finally, sometime in the late 1970s, Tiger completes the training of his last student, a young woman who becomes the Japanese action hero, Tyger. [“Judomaster: Mozambique: Situation Critical”]

  • Rocket Kelly battles his arch-nemesis Diablo again, saving the mystical Flame of Democracy from him and becoming the new Keeper of the Flame after the old keeper – a man of ancient Rome or Greece – dies. Note: The home of the Flame of Democracy is apparently a small planetoid with an artificial gravity field that looks much like Earth on its surface. It seems to exist in real space, despite the fact that the Flame of Democracy is also a symbolic concept. It is probable that the home of the Flame only exists in physical space whenever the Keeper of the Flame is replaced. [Rocket Kelly #1]

Note: Although the Martian nation of Zenoba is not identified as such, it is most likely this nation because all of its men are bald or balding, just like Zeltan Zamba, the Zenoban ruler of the year 2016 as seen in Space Adventures #30.

  • Fangs' last case. [Sparkling Stars #33]

  • On January 13, Mars seemingly explodes, causing widespread panic on Earth. In Rocket Kelly's last case, Kelly and his companions Sue Andrews and “Punchy” Waclawski return to the planet Selura and free it once more from Dr. Malik, who was thought long dead. Afterwards, Mars is visible once more, the explosion having been an optical illusion caused by Malik to extort money from Earth. Note: The supposed explosion of Mars and Malik's involvement is probably also connected with the Martian invasion of Earth on June 22, 1948, later this year. Probably Malik conspires with the Martian invaders. Sometime after this story, Kelly and Sue Andrews are married, and they have a daughter named Patricia Kelly who becomes a secret space explorer herself in the 1960s. Presumably, Rocket Kelly himself as the Keeper of the Flame of Democracy retires to the home of the Flame to live for centuries until a new keeper is chosen. [Tegra, Jungle Empress #1]

  • Prof. Dana Freidberg and writer Keith Roberts visit the site of a meteor crash in Helena, Montana, and discover that it was an extraterrestrial space ship. They then learn from Jason DeKoven, a Martian already living on Earth, that 411 atomic rocket ships from Mars have secretly landed in the same place on Earth since 1931, leaving over 40,000 Martians (who look human but are ten times as strong as humans) on Earth, with 7,000 in the United States and the rest scattered all over the world. The two learn that Mars will invade Earth on June 22. Note: The Martian invasion does begin on June 22, but the story of how it was repelled has yet to be told. The hostile Martian nation of Luravia (one of three Martian nations) is behind the invasion, and it is probable that the ruler of Luravia (which has existed since at least 1931) is overthrown at this time by the other two Martian nations, Zenoba (led by Zeltan Zamba) and Cloland (led by Queen Thula) and assisted by Montague Dexter (father of Rex Dexter of Mars). The actual invasion fleet is likely stopped by a large team of super-powered mystery men, with assistance by Rocket Kelly.

  • During an experiment, a physicist named Dr. Eustus Riko transports an ape into Dimension 2-K-31, resulting in the Creature from Dimension 2-K-31 (a genetically engineered, shape-changing, telepathic monster from that dimension) crossing into this world. The Creature appears on the battlefields of the Korean War and battles both American and North Korean soldiers before being trapped in a Russian tank within an air-sealed crate. Note: The Creature was created by the otherdimensional Katu of the world of Erehwon (“nowhere” spelled backwards) to be an unstoppable force to end all war. The fact that it was captured fairly simply on Earth simply means that it is still young and is still learning and adapting; it is possible that the Creature cannot be destroyed at all but only detained or transported away. Its only weakness seems to be steel, which draws the Creature magnetically to it and can trap it. [The Thing! (Charlton) #1]

  • A scientist named Dr. Lazarus creates a growth solution that can enlarge someone for a brief time, and he uses it to defeat his muscular bullying assistant in the wrestling ring. He plans to keep using the solution to become the most powerful man in the world, but instead one of his white rats ingests the solution and possibly him as well. Note: Although the story implies that Dr. Lazarus is eaten by the giant white rat, he may have somehow escaped that fate. [The Thing! (Charlton) #2]
  • Associate Prof. Steve Reynolds of State University creates Formula 87, a chemical that can rapidly accelerate plant growth. It inadvertently causes not only rapid plant growth but also causes plants to grow to monstrous size. Note: This story does not explain the fact that the simultaneous appearance of a new small planet entering Earth's orbit is the reason for the rapid plant (and fungus) growth caused by Formula 87. [“Green Death,” The Mysterious Traveler (1943 Mutual Broadcasting System radio series)]
  • A boy named Freddy stops the extraterrestrial invasion of a traveling gas planet populated by gaseous humanoids, who planned to poison the Earth and kill all its inhabitants. Note: Although the gas planet is strangely called Mars, other depictions of Mars contradict this story, so it must be another planet entirely. This planet is likely the same one destroyed by the Creature from Dimension 2-K-31. [“The Sentinel,” Tales of the Mysterious Traveler #2]
  • Several places across the world are afflicted by strange funguslike growths, although the effects are mostly localized. During this fungus epidemic, the Creature from Dimension 2-K-31 escapes from captivity as the Russian tank it is imprisoned within is taken apart by military scientists at the Pentagon in Washington, DC (which has been particularly afflicted by the fungus growths). The military hunts the Creature while the public mistakenly believes it to be the cause of the fungus growths, and several people try to hunt it down, leading to the biggest search the nation has ever known. After the Creature is cornered and forced to flee into a forest of fungus growths, it encounters a scientist named Dr. Zupa and learns by reading his mind that the cause of the fungus growths is the gravity pull of a small new planet entering Earth's orbit. The Creature takes action by changing into a gaseous form and rising into the outer atmosphere and into space, where it surrounded the small planet in the form of a cloud formation and struck the planet with lightning all across its surface, burning and sterilizing it for three days. The Creature finally succeeds in pulverizing the small planet into dust. It then returns to Earth in a small gaseous form but becomes magnetically drawn into a molten iron meteor and is entrapped within it as the meteor buries itself into a desert, where it presumably still lies entrapped. Meanwhile, the fungus growths around the world all disappear with the destruction of the small planet. Note: The cause of the strange growths is undoubtedly Formula 87, which was created by Prof. Steve Reynolds (see “Green Death”). It is probable that the simultaneous appearance of a new small planet in Earth's orbit somehow creates a hothouse effect enabling extreme plant growth. Although it is not depicted in this story, there is also a great deal of plant growth in addition to fungus growth. [The Thing! (Charlton) #2]

When the Martians bring Jackson, along with a horse and his ranch hands Hank Roper and Strong Bow, back to Mars with them, Jackson learns that Queen Thula must give up her rulership over Mars because Korok claims to have conquered the Earth. Jackson wins Thula's throne back for her and ends up becoming prime minister of Mars. Becoming known as the Space Vigilantes, and equipped with a Martian spaceship and armed with six-guns that fire miniature atomic bombs,“ they fight various menaces on both Earth and Mars, including outlaws, evil Martians, and Nazis in space.

After defeating the crooks and freeing the scientists, Jackson returns to Venus on a robotic winged horse, then flies the rocketship back to Earth. Note: The robotic winged horses are never explained, but they must have been built by a spacefaring race and equipped with force-fields to keep breathable air during space voyages.

A criminal scientist named Marko murders Dr. Karasz and seizes his robots and attunes the thought-control device to his own brainwaves. Marko then tries to use the robots to take over the city but is not taken seriously. After giving the order to destroy all humanity, the robots first turn on him and then stop working.

On the way to a planned Moon landing as part of a secret space program, Gord reveals himself as a Martian and hijacks the ship in order to return to Mars. He explains that flying saucers are from Mars, and he and his crew crashed in the Himalayas, and he has sought to return to Mars ever since. Back on Earth, the four people on the rocketship are believed to have died in space in a failed mission. Note: The rocketship and space flight, as part of a secret space program, are classified and unknown to the public. It is probable that the Martian from this story was part of the failed Martian Invasion of June 22, 1948. [Space Adventures #7]

  • A middle-aged man identified only as the Teller of Tales begins telling stories of horror from his personal library. He keeps company with monsters who also act as storytellers called Freddie Demon, Garry Ghoul, Victor Vampire, and Walter Werewolf, although it should be noted that these are not their real names, since the Teller admits to making up these comical aliases for his own amusement. The Teller's true name is Walker, a former scientist who was caught in an explosion while experimenting with radioactive isotopes and through the accident gained amazing mental powers and the ability to see through walls and read anyone's mind. While he originally attempted to use his powers to help people, he soon found that he could not change fate and became an observer. [Horrific #8]

November, 1953

  • A morally bankrupt scientist named Herman Lindsay creates a formula that enables his dog Fido to speak and have human intelligence. After teaching him English and how to read, Lindsay uses Fido to case his friends' houses and find out combinations to safes and other information that enables him to steal from them. Unfortunately for him, Fido is an honest dog and turns him in to the police. Presumably Fido retains his intelligence and ability to speak and finds another home. [“The Day Fido Sang,” Space Adventures #9]
  • A criminal scientist named Max Murphy invents a substance in pill form that vastly increases his metabolism and enables him to move at a speed up to a thousand miles per hour. Using his super-speed, Murphy robs a bank but only ends up with decoy money. When he attempts to rob a bank in another city, he is instantly killed when he crashes into metal doors at high speed. [“Screaming Shoes,” Voodoo (Ajax-Farrell) #13]
  • Dr. James Boyle invents a drug called muiclac, which is meant to treat people with brittle bones by softening them. Taking muiclac, his patient Lawrence Dawson gains the ability to stretch his body and manipulate it like rubber, and he realizes he can become rich and famous because of this ability. Dawson, fearing Dr. Boyle will give the drug to another who will gain the same ability, kills him. Fleeing from the law, he finds that his stretched body is becoming loose and won't return to his original appearance. He seeks the help of scientist Dr. Harrell, a friend of Dr. Boyle, but murders Harrell out of fear before receiving a treatment. When the police track him down at his apartment, he takes the rest of the bottle of muiclac, and his body liquifies, apparently killing him. [“Stretching Things,” Fantastic Fears #5]

  • Death itself appears in the form of Doctor Death for the first time. [This Magazine Is Haunted (Charlton) #15]
  • The mummy of Rah Kamsis, an ancient Egyptian sorceress and witch of the dead, is briefly brought back to life by a ray invented by the famous scientist Prof. Vincent Huntley, who happens to be a direct descendant of Tutankhamun, the Pharaoh who entombed Rah Kamsis. After Prof. Huntley brings the mummy of Rah Kamsis back to his estate to display his revival ray, the mummy murders Huntley and drains his life force, then kills several other scientists there. The mummy then attempts to place Rah Kamsis' soul into Huntley's daughter Karen, Tutankhamun's last descendant. Huntley's assistant Steve Drake uses the black book entombed with the mummy to summon the spirit of Tutankhamun, who finally defeats Rah Kamsis once and for all. Note: Rah Kamsis is likely a protege of the Egyptian sorceress Hatshepsut II, known as Princess Evila, sorceress of the Nile, who rose to power some 50 years before Rah Kamsis' own rise to power in ancient Egypt. Steve Drake and Karen Huntley survive and probably marry and reproduce sometime after this story, allowing the descended line of good King Tut to continue. [The Thing! (Charlton) #12]

  • Three members of the U.S. Navy – Capt. Small, Robert Crane, and Huey – are rescued during the destruction of submarine R-93 and brought to an underwater, domed city of Atlantis by fish-men (also known as gill-men) ruled by air-breathing humans. There, they meet Queen Shar-La who asks for their help to restore their light source with a repaired atomic engine. Unfortunately, after Crane and Shar-La fall in love and she chooses him as her royal consort, the Atlanteans led by elder Valyon rebel. Then the weight of the atomic engine causes the destruction of the city's dome and kills the entire population, along with Shar-La and Crane. Only Capt. Small and Huey survive to tell the tale. Note: This city of Atlantis is only one of several, and it is the only one in which the survivors have not become water-breathers, instead allying themselves with the frog-men who act as their underwater messengers and servants.

  • After a few years of special classified work overseas for the Central Intelligence Department, Dan Garret returns to the U.S. Still a CID agent, he rejoins the New York Police Department as his cover and resumes his Blue Beetle mystery man career, marking the beginning of a new (although brief) era of mystery men, which finally ends with the disappearance of Nature Boy at the end of the 1950s. Note: This story is a reprint, and the first new Blue Beetle story is not until Blue Beetle (Charlton) #20, but this issue can be marked as Blue Beetle's return. Although Joan Mason (now a redhead) and Mike Mannigan call Dan Garret a rookie, they mean it as a friendly jibe aimed at him after his return to the NYPD after his third absence from the police force (the first was from 1942-1944, the second was from 1948-1950, and the third was from 1950-1954). As part of his cover as a secret CID agent, Dan also acts much less competent than he really is. [Space Adventures #13]
  • The Black Cobra resumes his mystery man career as a communist spy smasher. An office boy at the FBI becomes his teenaged crime-fighting partner, the Cobra Kid II. [Black Cobra (Ajax-Farrell) #1]

November, 1954

  • Crime Smasher, a man who is considered America's number one private detective and who owns and operates Crime Smasher, Inc., has a single known case. He is assisted by his girl friday, Eve Corby. Note: The individual known as Crime Smasher may or may not be Sam Spolo, known in the 1960s by the nickname of the Spy Smasher. In any case, this Crime Smasher is the Earth-4 counterpart of the Crime Smasher of Earth-S, while Eve Corby is the Earth-4 version of the Earth-S Eve Corby. [Badge of Justice #22]

1955

January, 1955

  • Yarko the Great, mightiest magician of all time, returns for a single case in which he combats a group of Viking warriors that had been preserved in the ice for a thousand years and thawed out by a criminal. Note: This story is actually an Ibis the Invincible story reprinted from Whiz Comics #45, with the year updated from 1943 to 1955. Since this is merely a reprint and not an original Ibis story, we conclude that there is no Ibis the Invincible on Earth-4. Rather, Yarko the Great acted as a substitution in this story, assisted by an unnamed wife (in place of Ibis' wife Taia) whose identity has not yet been revealed. [Danger and Adventure #22]
  • Wonder Boy, an alien boy with super-strength, begins adventures. Note: This is the Earth-4 version of Wonder Boy and is not the same character as the original version published by Quality Comics, as this version is a boy in the 1950s, while the original was a boy in the 1940s. The Quality version of Wonder Boy exists on Earth-X. [Terrific Comics (Ajax-Farrell) #16]

  • Samson resumes his mystery man career. [Samson (Ajax-Farrell) #12]
  • Donning a power-suit slightly boosting his agility, speed, and strength, Rip Regan becomes the globetrotting mystery man known as the Red Rocket and has a single case. Note: This story is edited and slightly redrawn from a Power-Man story from Fight Comics #14, published by Fiction House. Because of this, the Red Rocket can be considered the Earth-4 version of Power-Man. Although the Red Rocket's identity is never stated in this story, he probably has the name Rip Regan, which is Power-Man's identity. This Red Rocket is not the same character as the Red Rocket of the year 2042 AD, published in Captain Flight Comics by Four Star Publications. The 2042 Red Rocket (Rod Page) is probably a descendant of Rip Regan. [Phantom Lady (Ajax-Farrell) #3]

Note: The 1940s Sherlock Holmes series featuring Basil Rathbone – beginning with Sherlock Holmes and the Voice of Terror (1942) and ending with Dressed to Kill (1946) – may feature the same character, a Sherlock Holmes who operates in contemporary times (in that case World War II) without having aged at all since the Victorian Era.

Protto plays along but secretly conspires with the U.S. Army to put in place a real defense plan in Washington, D.C., since the so-called Texas billionaire is actually a Martian named Egro. The U.S. Army successfully defeats this entire small Martian fleet as it attacks the city. Note: Egro and his servant Sporo are both bald, short, human-looking men who look similar to the inhabitants of the nation of Zenoba on Mars. It is likely that the public was told that this invasion was actually staged as part of the flying saucer film production. [“Paul Protto Productions,” Unusual Tales #3]
